In some embodiments, the system includes waterproof earphones for generating audio signals to a user's ear while the ear is underwater. In some embodiments, the system includes methods for waterproofing an audio device that generates signals that are convertible to audio signals. Current technology does not allow for the reliable submersion of audio devices into aquatic environments or for the use of such audio devices in environments where they will be exposed to water. Furthermore, there exists only limited technology for the transmission of audio waves to a user submerged in such an aquatic environment.
- Underwater submersion of earphones and audio devices require consideration of the effects of water and pressure on sensitive electronic components. In addition to the mechanical effects of pressure underwater, water pressure also promotes seepage of water into sensitive areas. Thus, in some embodiments, the devices disclosed herein are adapted to resist pressures encountered under water. In some embodiments, the devices are waterproof and pressure resistant to depths of up to 3 feet. In other embodiments, the devices are waterproof and pressure resistant to depths of up to 10 feet. In other embodiments, the devices are waterproof and pressure resistant to depths of up to 20 feet. In other embodiments, the devices are waterproof and pressure resistant to depths of up to 50 feet. In other embodiments, the devices are waterproof and pressure resistant to depths of up to 100 feet. In other embodiments, the devices are waterproof and pressure resistant to depths of up to 300 feet. In some embodiments, the devices are adapted to withstand the pressure experienced by a SCUBA diver.
- As used herein, “waterproof” means that the device referred to as “waterproof” is capable of being completely submerged under water for a substantial period of time without water penetrating a “waterproof” barrier. The substantial period of time may include 30 seconds, 1 minute, 1 hour, or greater than 1 hour.
- As used herein “aquatic environment” refers to an environment that is at least partially exposed to water. The exposure to water may come from being submerged or partially submerged in water or may come from exposure to droplets or streams of water, such as caused by splashing.
- As used herein “aquatic activity” or “watersports” refers to any activity in which the participant is exposed to an aquatic environment as defined above.
- In other embodiments, housings are provided that are not waterproof but are water resistant, providing protection for an audio device when used in applications where contact with water is incidental (e.g., snow related activities and exposure to rain). In still other embodiments, housings are provided that are not waterproof but are shock resistant, allowing the audio device to be used in rugged environments and activities.
- The advent of miniaturized electronic devices such as audio players and communication equipment has made feasible the individual use of such devices during recreational and educational activities. Herein is disclosed a system for using a personal portable audio device while being submerged into an aquatic environment. Although some embodiments of the systems described herein may be waterproof under submersible conditions, such waterproof systems may also find application in activities where contact with water is incidental. Non-limiting examples include boating, jet skiing, winter sports such as downhill and cross-country skiing, snowboarding, and sledding, and activities where the user will encounter mud such as off-road motorcycling or ATV use.
- In one embodiment, a rigid container capable of withstanding the pressure encountered while submerged into an aquatic environment is provided. Such a container can be made from any material capable of withstanding pressure, including but not limited to metal, ceramics, glass, rubber or plastic compositions.
- One embodiment includes providing the rigid container with a removable lid, for easy removal or service of the device contained within. In one embodiment, at least one waterproof seal is positioned between the lid and container to prevent entry of water into the closed container. One skilled in the art is aware of multiple ways of providing a waterproof seal between a lid and a container. Without intent to limit the scope of the invention disclosed herein, such seals may consist of one or more of the following: an o-ring, rubber lining, or a silicon-based gel. In a preferred embodiment, at least one o-ring seal is positioned within a recessed grove along the perimeter of the lid's underside. In a more preferred embodiment, the lid is provided with two levels. Level two is positioned within the step provided by the container box and above the device, adding horizontal strength to the housing. The first level contains at least one o-ring seal in a recessed grove positioned between level two and the outer perimeter of the lid. The lid may further be removable, or attached to the housing using hinges or similar devices.
- One embodiment includes the use of components to secure the lid to the container and to close the seal between the lid and container. A person skilled in the art is aware of multiple devices with which to secure a lid to a container, including buckles straps or clips. Such locking devices may be positioned on the lid, on the container, or may be positioned on both the lid and the container. In a preferred embodiment, the locking components comprise safety features preventing accidental opening of the lid during its use. Such safety features include any design with the intended purpose of preventing accidental opening of the lock, for example catches, push pins and rotary dials. In a most preferred embodiment, a buckle is specially designed to lock when snapped shut. In some embodiments, to unlock the device at least two fingers are required: one for holding down a safety latch and one for lifting the buckle.
- Without limiting the scope of the invention disclosed herein, one preferred embodiment of the disclosure is depicted in FIGS. 1 to 3. The submersible housing system of
FIG. 1 is a container unit with a bottom, front, back, left, and right side designed to snugly contain an electronic device. Thelid 7 is made of a rigid material, preferably clear, that fits over the top 19 left, right, front, and back edges of the container. In the face down side of the lid is an o-ring 8 that sits in a recessed grove along the perimeter of the underside of the lid. The compression contact between the o-ring and thetop edge 19 of the housing provides the hydrostatic seal. The lid has two levels as seen inFIGS. 1 and 3 . Level two is designed to sit above the device and within the step provided in the container box. This will serve the function of adding horizontal strength to the housing and ensuring the prevention of a change in structure, which could result in a break of the hydrostatic seal, causing a leak. The first level is designed to contain an o-ring 18 in a recessed grove located between level one and the outer perimeter of the lid on the face down side. This o-ring 18 will be compressed on the perimeter of the top 19 of the container box to make a seal that is not only water resistant and waterproof, but also submersible to one or more pressures absolute while maintaining a hydrostatic seal against the environment. - In order to secure the seal, the preferred embodiment will contain
buckles 15 located on the peripheral exterior that will snap and lock the lid to the container. Such a buckle is manufactured by NEILSEN/SESSIONS® and is specially designed to lock when snapped shut, thus preventing accidental unsnapping of the buckle that could potentially release the lid from the container breaking the hydrostatic seal. To unlock the device, two fingers are required: one to hold down the safety latch down while the second finger lifts the buckle.FIG. 6 shows anexemplary latch 60 that may be alternatively used to perform the functions ofbuckles 15.Latch 60 may be, for example, a compression spring catch such as that manufactured by NIELSEN/SESSIONS® under product number I-HC83314-42LALBSS. In order to completely releaselatch 60, an operator must actuate aprimary catch 62 as well as a spring loaded mechanism 64 (i.e., a secondary catch). If both catches 62 and 64 are not released, thelatch 60 will not open. Hence, the design oflatch 60 both ensures that the lid remains securely attached to the housing, and that thelatch 60 will not be accidentally released. - In some embodiments, devices are provided that comprise one or more components that prevent water from reaching and damaging the audio device. Such components may act to prevent a leakage from occurring, or to reduce the damage of water should a leak have occurred. Such components may include external shock-absorbing structures, pressure release valves, multiple seals, internal walls creating waterproof compartments or chambers, and water-absorbing materials within the container.
-
FIGS. 7A-7D show alternative ways to adapt thelid 7 and the container shown inFIG. 1 to protect the audio device from water damage.FIG. 7A shows a cross-section of the container depicted inFIG. 1 having asurface 70 in the form ofmultiple peaks 72 andtroughs 74. In this example, thesurface 70 would be part of the housing itself, i.e., manufactured as one integral unit. An audio device would rest upon thepeaks 72, thereby being isolated from any leaked water, which would pool in thetroughs 74.FIG. 7B shows a cross-section of the housing having aprotective surface 76 which resembles the structure shown inFIG. 7A . In this embodiment, however, theprotective surface 76 would be a removable lining, i.e., not necessarily built into the housing. Such aprotective surface 76 may be attached to the housing with an adhesive, for example.Protective surface 76 may be made of a water absorbing and resilient material in order to protect the device from both water damage and mechanical shocks. Similarly to thesurface 70 described above,surface 76 would allow for the device to sit atop thepeaks 78 while the water is collected and absorbed at thetroughs 80. -
FIG. 7C shows yet another embodiment of the housing depicted inFIG. 1 having aprotective surface 82. In this example,protective surface 82 is a lining of water absorbing material. Such water-absorbing materials include all compounds with desiccant or hydrophilic properties or any material with water-absorbing capacity, for example provided in the form of fabrics, sponges, foams, powders, pellets or similar. The material may be of synthetic or organic origin, or a combination thereof. - It should be noted that while the examples discussed above show only one surface of the container having the
respective protecting structure protective structures -
FIG. 7D shows yet another embodiment of the housing having features to protect the internal unit from water damage in case of a water leak. In this embodiment, a one-way valve 84 is affixed to an inner surface of the housing unit. The one-way valve 84 allows water to pass from the inside of the housing to awater storage chamber 86. Since the one-way valve 84 allows passage of water in only one direction, the audio device is protected from water leakage in that the leaked water is removed to and stored in thechamber 86. A person of ordinary skill in the art will recognize that a variety of commercially available one-way valves may be used, and that the size, shape, and location of thechamber 86 may vary according to the desired design of the housing. - Some embodiments may further include the use of safety devices designed to increase the internal gaseous pressure of the container in case of a water leak. Without intent to limit the scope of the invention, such devices may include pressurized gas released upon leakage or chemical compounds, such as carbides, that produce gases upon exposure to water. In some embodiments, the invention comprises the use of one-way valves to reduce or increase the gaseous pressure within the container. Some embodiments include the use of any waterproof contrivance capable of conveying a one-direction flow of gas including, but not limited to, pressure release valves and vacuum release valves. In one embodiment the one-way valve is capable of withstanding the aquatic pressure exceeding one atmosphere.
- In some embodiments, the invention comprises a moisture sensor within the container to detect water leakage into the container. One skilled in the art is aware of multiple types of sensors designed to detect an increase in humidity or moisture. The invention embodies any electrical moisture detection device including but not limited to led sensors or conductivity meters, and any chemical means of detecting moisture including, but not limited to, chromophoric substances.
- In some embodiments, the invention comprises an internal lighting source to illuminate the device contained within. The invention is not limited to any particular source of light waves, but embodies any device that would achieve the intended purpose. For example, lighting sources include any electrical, chemical or biological process of producing light within the visible range. Such lighting sources may be mounted either on the outside or the inside of the container, or both. In some embodiments, fluorescently or similarly labeled components are used within or outside of the container to illuminate the device or to make one or more components of the device, for example the control knobs, visible under conditions of limited light.
- In some embodiments, the device includes components for monitoring the operation of the audio device within the container. Such systems include, but are not limited to, visual, chemical and electrical. In one preferred embodiment, the container is partially manufactured from a transparent material. Such materials include, for example, glass, plexiglass or plastic. In another preferred embodiment, the container harbors circuitry that is capable of monitoring the electrical operation of the audio device. Such circuitry includes, but is not limited to, power meter, voltage meter, resistance meter and thermometer. For example, the circuitry may indicate whether a battery used to power the audio device is running low or to monitor other aspects of the operation of the audio device. In some embodiments, the device comprises components for communicating information on the operation of the electrical device to the user. Without limiting the scope of the invention claimed herein, such means include generation of audio signals and light signals, and visualization of instrument readings on a LED or similar display.
- The invention embodies use of the container with any conceivable device capable of producing an audio signal or an audible sound. The invention embodies the use of any audio device including, but not limited to an audio player, iPod® device, MP3 player, CD player, cassette player, DVD player, communication device, telephone, cellular telephone, radio receiver, radio transmitter, computer, laptop computer, palm pilot, personal digital assistant, pager, measuring device, geiger counter, sonar, pH meter, thermometer, luminometer, magnetometer, or personal gaming device. In one embodiment, the audio device produces information on underwater sightings and points of interest relating to a specific underwater location. Such information may be stored on the audio device, or be received by the device from a source outside of the housing. For example, the information provided to the audio device or stored on the audio device may be used to provide an underwater tour of a specific location. In some embodiments, the device of the present invention comprises internal circuitry capable of receiving information from external devices such as a dive computer. In a preferred embodiment, the information received is communicated through the circuit to the user by, for example, light signals or audio signals.
- In some embodiments, the device comprises components for attaching the container to the user's body or equipment. Such attachment features include, for example, straps, clips, hooks and various materials with adherent properties such as glue or tape. In one preferred embodiment, the container is provided with external features facilitating attachment to the user's body, for instance providing the container with an outer surface shaped to fit an appendage or other area of the body to which it is desired to affix the device. The container may be adapted to fit a leg, an arm or the thorax.
FIG. 8A shows an example of acontainer 800 having a contouredsurface 801 designed to fit over a thigh of a user. Thecontoured surface 801 may be pre-molded into the housing, or may be provided as a detachable piece that can be attached or removed depending on the type of use. In some embodiments, the features for attaching the device to the user's body may comprise a rigid surface configured to comfortably fit on the desired portion of the body or the features for attaching the device to the user's body may comprise flexible components which conform to the desired portion of the user's body. In the example ofFIG. 8A , anelastic strap 803 is used to attach the container to the thigh of a user. - With reference to
FIGS. 8A-8C , an embodiment of the housing is shown having a round shape, as opposed to the rectangular shape of the housing shown inFIG. 1 . In some embodiments, theround container 800 may have a threadedsurface 804 to engage a threadedsurface 805 on thelid 802. This embodiment allows for the storage of anaudio device 806 inside thecontainer 800 andlid 802 without the need for external latches or buckles.FIG. 8A also shows aspeaker system assembly 807 to be used in conjunction with the housing and thedevice 806.FIGS. 8B and 8C show, respectively, the top and side views of the housing shown inFIG. 8A . - In some embodiments, the device of the present invention comprises components for manually controlling the device within the closed container. Such control devices may comprise components external to the container, components internal to the container, or both external and internal components. In some embodiments, the components are waterproof and/or capable of withstanding activation by water pressures encountered while submersed to depths including 3 feet, 10 feet, 30 feet, 50 feet, 100 feet, or 300 feet. Without limiting the scope of the invention, control components suitable for manipulating the device within the container include knobs, camshafts, push pins, soft rubber moldings and electronic control devices. In one embodiment the container or lid harbors one such external control device. In a preferred embodiment the container or lid harbors multiple external control devices. In a most preferred embodiment, the container or lid harbors a number of control devices spatially arranged so as to optimally operate the controls of a specific audio device within the container. In one preferred embodiment, the external control components are capable of horizontal and vertical movement, and capable of generating both horizontal and vertical movement of the internal components of the controlling device. In a more preferred embodiment visualized in
FIGS. 1-3 , acontrol knob 4 allows the user's to rotate an internalpressing device 11 so that a push button controller on the entertainment device can be activated externally while maintaining a hydrostatic seal against the environment. In an arbitrarily located position, relevant to the device sitting in the housing system, acontrol knob 4 made of a rigid material is placed through thelid 7 to allow exterior manipulation of the activation devices of the device. The control knob system is a comprised of acamshaft 13 surrounded by an o-ring housing 33 with aknob 4 on the exterior end, and ahex screw 10caddy 12 and apresser 11, on the interior end. Thus, thepresser structure 11 can be positioned anywhere along a 360 degree location on a horizontal axis by turning theknob 4 in therotation chamber 32. The vertical position can be manipulated from the exterior by pressing theknob 4. In order to deal with the constant inward pressure, anexterior spring 5 pushes the knob back up to its original position. The result is a vertical and horizontal movement control of thecaddy 12 andpresser 11 used to control the interior device. - A person of ordinary skill in the art will recognize that the shape of the
control knob 4 need not be limited to that already described. For example,FIG. 9 shows an embodiment of the housingunit having controls control 901 may interact with the analogous “rewind” control of the audio device. Similarly,control 902 may actuate the “forward” button of the internal control device. While the external configuration of the controls of the housing may adopt any of a variety of shapes, the actuating mechanism that allows for waterproof operation may be the same as already described above.FIG. 9 also shows aspeaker system assembly 905.FIG. 9 also depicts an embodiment of the housing having asurface 906 that is adaptable to be worn on an appendage, e.g., a thigh, of a user. - In some embodiments, the invention further embodies components for connecting the internal audio device to an audio output adapter. The audio output adapter may include, but is not limited to, an audio jack including RCA jacks or a 3.5 mm stereo jack, USB port, Ethernet RJ45 port, Firewire, phone jack, multipin serial connection, wireless transmitter.

The audio communication link provides for communication between the audio output adapter and a sound generating device, such as an earphone. The audio communication link may include a wired link or a wireless link.
- Positioning of an audio jack may be on the inside of, on the outside of, or within the housing. In some embodiments, the invention also comprises components that are waterproof and components that can withstand water pressures. In some embodiments, the invention comprises the use of any coupling mechanism capable of achieving the purpose of connecting the audio device to an audio communication link including, but not limited to, pneumatic coupling, threaded coupling, snap-in, push-in, lock-in and permanent. In a preferred embodiment, the wires from the stereo jack make a connection to a stereo jack adapter located in the body wall of the housing. The stereo jack adapter sits within the bore of a male hydraulic nipple that lies flush with exterior end. An o-ring between the body wall and the male hydraulic nipple establishes a hydrostatic seal.
- In a further embodiment of the invention, components connecting the audio jack to an audio communication link are provided. In some embodiments, the invention also comprises components that are waterproof and components that can withstand water pressures. The invention further comprises the use of any coupling mechanism capable of achieving the purpose of connecting the audio jack to an audio communication link including, but not limited to, pneumatic coupling, threaded coupling, snap-in, push-in, lock-in and permanent. In one preferred embodiment disclosed in FIGS. 1 to 3, a
stereo jack 20 plugs into the device so that the sound is transmitted from the device through a short flexible slack ofcable 16. This will allow the electronic device to be easily connected, and inserted in the housing. This also allows the flexibility and adaptability function by using any type of device that is equipped with an audio jack. The wires from thestereo jack 20 make aconnection 17 to astereo jack adapter 30 located in thebody wall 18 of the housing. This stereo jack adapter sits within the bore of a malehydraulic nipple 31 that lies flush with exterior end. There is an o-ring 29 between thebody wall 18 and the malehydraulic nipple 31 that establishes a hydrostatic seal. This entire stereo jack adapter is designed to screw into the body wall and serves as a means of providing an easily replaceable, and fixed, pressure resistant audio jack adapter that can withstand water pressures while maintaining a hydrostatic seal against the water environment, and, that plugs into a stereo device. Coupling to the malehydraulic nipple 31 is the female hydraulic couplerFIG. 3 that has a built-instereo jack 21. The female coupler is snapped over the male hydraulic nipple with a lockingbearing 24 mechanism to establish a hydrostatic audio connection by means of a locking mechanism to the male coupler. This operates by sliding theouter shell 22 away from the port. This action allows theinternal ball bearing 24 to slide out from the interior through the holes in the interior shell when inserting themale nipple 31 into thefemale coupler 21. As such, a secure connection is established. This occurs because thejack 21 that is inside the female coupler fits into theadapter 30 within the male coupler. Releasing the slidingshell 22 causes theinternal spring 34 to push theouter shell 22 towards the port whereby theball bearings 24 are once again pushed through the holes in theinterior shell 23. Theball bearing 24 then fit into thegroove 28 of the male coupler, preventing the two units from separating. A hydrostatic seal is established by this juncture. The female coupler contains an o-ring 35 inside to provide a hydrostatic seal capable of withstanding one or more pressure absolute. The flat, front edge, of the male coupler makes contact with the o-ring. When the slidingshell 22 is released and the ball bearings fit in thegroove 28, it initiates a small degree of compression on the juncture that drives the front edge of the male couple deeper into the internal o-ring 35 of the female couple. Thus, a hydrostatic seal is established that provides for a pressure resistant and waterproof juncture between the male and female adapters. This unit has the benefit that it can rotate around the axis without breaking the seal. In addition, this unit will allow the user to completely disengage and reestablish the connection underwater without flooding and damaging the interior of the housing because the male and female hydraulic couplers are completely internally sealed components. The male coupler contains a solid flexible filling 29 such as silicone or rubber, which prevents water from entering. The female coupler contains a thick o-ring 35 internally. This is important because if for any reason the cable pulls apart from the housing then the housing unit will not flood and destroy the electronic device. - In some embodiments, the device of the present invention comprises an audio communication link between the housing and a device capable of generating audible sound.

- Some embodiments are disclosed in FIGS. 4 to 5. The headset utilizes a
frame 39 to which thespeaker arm 44 is mounted. The frame is rigid and comprises aswivel 43 and a hollow chamber through which a mask strap feeds. This will allow for horizontal adjustment by sliding, and for vertical adjustment by rotating the arm of the swivel. Thus, a user can position the speaker to personal and custom coordinates. Thespeaker arm 44 is a concave frame withspeakers 46 mounted on the ends. Angular adjustments allow the user to specifically orient the speakers in three-dimensional space to suit personal coordinates. In this embodiment, the user can position the speakers near the ears, directing the sound waves into the ear canal but not restricting the canal passageways. This feature is particularly useful for divers such as SCUBA or skin divers, allowing the diver the ability to equalize pressure of the sinus and ear canals with the ambient pressure of the environment. -
FIG. 10 shows two views of aframe 1002 which may be utilized with the speaker system assembly ofFIG. 5 . In this embodiment, theframe 1002 consists of aportion 1004 for attaching theframe 1002 to the mask strap of a user wearing an underwater mask, such as a snorkeling mask, diving mask, or swimming goggles. Theframe 1002 further consists of aportion 1006 to which the speaker housing may be affixed using, for example, a screw-hole 1008. Theframe 1002 may be further provided with throughholes FIG. 1 .Frame 1002 may be made from a rubber material to provide both firmness and elasticity, as well as a soft feel. Alternatively,frame 1002 may be made of suitable plastic or aluminum materials. - The wire cable runs through the
membrane 46 of the securely sealed speaker housing to the piezoelectric 52, 53, 55 ceramic speaker elements with a 20 Hz to 25 kHz frequency range. This range is advantageous in the design of the speakers because they can work with an amplifier to correct for aquatic dampening effect. The three speakers are designed to operate at fidelity levels heard out of water, while underwater. Due to the dampening effect of water, the frequency ranges for the dampened wavelengths are compensated. Thus, out of water, the audio may not sound normal. However being underwater, they provide fidelity without loss of clarity. A rigid yetnondense diaphragm 51 comprising of such materials as fiber-reinforced epoxy, vinyl, mylar, polyester, ABS resin or the like, covers the speakers covers the outside. This will allow the sound to travel through the diagram with the least resistance and serve to move the diaphragm for increased sound fidelity. It is a permanent structure and should be sealed and fixed. - In another embodiment shown in
FIG. 4 , a wireless receiver system is equipped into the mask strap system. Awireless receiver 49 is connected to ananalog converter 50, which then send the audio signal to the speakers viacables 42 a, 42 b. Aswitch 47 allows the user to control the power. The switch is covered with a flexible nonpermeable membrane that can toggle to an on or off position. Abattery 48 provides the power to wireless receiver system. The battery is secured from the environment within the receiver system and can be easily replaced by unscrewing a side port lid and sliding the battery out for replacement. Theinterior circuitry 56 of thespeakers FIG. 5 the mid-range frequency speaker provides greater signal amplification than thelow range 55 andhigh range 52 speakers. Thus, in effect, the audio fidelity heard underwater is maintained by over amplification of dampened frequency ranges. For those seeking to use a system that maintains the highest audio fidelity while underwater, this device provides enhancements over other systems. -

The controls include ajoystick interface assembly 2200 for controlling a joystick feature on the electronic audio device andbuttons 2115 for controlling push buttons on the electronic audio device.Lid 2101 features a substantiallytransparent window section 2103 where the display of the electronic audio device disposed within can be observed.Lid 2101 andbase 2102 are attached via ahinge 2120.Base 2102 andlid 2101 may be secured together to form a waterproof seal using a latch made up of anupper latch 2104 and alower latch 2105 that feature alocking mechanism 2106. The inside of the housing features amale audio jack 2107 that is electrically connected to a femaleaudio communication link 2109. The femaleaudio communication link 2109 is surrounded by afastener 2108 that may be used to create a waterproof seal around thecommunication link 2109. For example, earphones or speakers may be provided having a male plug surrounded by a flexible skirt. The skirt may be secured around thefastener 2108 when the male plug is plugged into thecommunication link 2109 such that a connection free of water ingress is created. Those of skill in the art will recognize that multiple ways to create a seal around the audio communication link exist, such as internal sealing, male and female coupling, gaskets, and co-molding techniques. - The
joystick interface assembly 2200 is shown in greater detail inFIGS. 22A, 22B , and 22C.FIG. 22A shows the joystick interface assembled into the housing, complete with afunction pad 2204 and adecoration sheet 2201 to indicate which direction the control interface may be moved to get the desired effect of the electronic device.FIGS. 22B and 22C shows exploded views of thejoystick interface assembly 2200. Thedecoration sheet 2201 covers clampingpiece 2202, which is held into thehousing lid 2101 usingfasteners 2103. One skilled the art would recognize many different methods of fastening a control feature into the housing, such as, but not limited to, screw, bolts, snap fit components, adhesives, press fits, co-molded components, overmolded components, ultrasonically welded components, rotational fits, wedge fits, and other manufacturing means of effecting the assembly of components. The clamping piece forces thefunction pad 2204 against thehousing lid 2101. The function pad may be made of a flexible waterproof material such as silicone rubber. Thus, thefunction pad 2204 may also serve the function of creating a waterproof seal about the control opening in thelid 2101. Those of skill in the art will recognize that many different materials could be used to create a waterproof seal between thefunction pad 2204 and the opening in thehousing lid 2101. The material and design geometry chosen provides not only a waterproof seal, but also an elasticity that allows manipulations of the electronic audio device, and enough rigidity to return to a neutral position after each use. Ajoystick contact device 2210 is provided for contacting the top of a joystick on the electronic audio device. When a user manipulates thefunction pad 2204, thejoystick contact device 2210 will push the joystick in the desired direction. - The
button assembly 2115 is shown inFIGS. 22D and 22E .FIG. 22D depicts the assembledbutton assembly 2115 andFIG. 22E shows an exploded view. Adecoration sheet 2151 covers aclamping piece 2152, which is held into thehousing base 2102 usingfasteners 2153. One skilled the art would recognize many different methods of fastening a control feature into the housing, such as, but not limited to, screw, bolts, snap fit components, adhesives, press fits, co-molded components, overmolded components, ultrasonically welded components, rotational fits, wedge fits, and other manufacturing means of effecting the assembly of components. Aunitary button pad 2155 is held against thehousing base 2102 by clampingpiece 2152. Thebutton pad 2155 may be constructed of a waterproof flexible material such as silicone rubber. Thus, thebutton pad 2155 may also serve the function of creating a waterproof seal about the control opening in thebase 2102. The material and design geometry chosen provides not only a waterproof seal, but also an elasticity that allows manipulations of the electronic audio device, and enough rigidity to return to a neutral position after each use. - In some embodiments, a protective housing is provided that contains features that allow control of electronic audio devices that have touch sensitive surfaces. As used herein, a “touch sensitive surface” includes any electronic device interface feature that includes a surface that responds to touch by a human finger. Touch sensitive surfaces can include capacitive sensitive surfaces that respond to the conductive properties of human touch as well as pressure sensitive surfaces that respond to applied pressure. One series of devices utilizing a touch sensitive surface are the iPod® line of portable audio players manufactured by Apple Computer, Inc, Cupertino, Calif. These devices contain a static circular wheel structure that features a capacitive sensitive surface that responds to the conductive properties of human touch, measuring the position of the finger on the touch pad. In order to control such a feature through a protective housing (e.g., a waterproof, water resistant, or shock resistant housing), a control mechanism can be provided that will transfer or contain an electric charge from the user's finger that replicates the position of the control on the device as if the user were directly touching the touch pad. Such a control mechanism can utilize conductive material to transfer charge from a human finger to the proximity of the touch sensitive surface.

FIGS. 23A and 23B show one embodiment of a housing utilizing a control mechanism for controlling a touch sensitive surface.FIG. 23A shows the system in perspective view with the lid open andFIG. 23B shows a cross-sectional view with the lid closed. Anaudio device 2350, with a touchsensitive control feature 2351, clicking push-button button 2353, anddisplay screen 2352 is shown. The protective housing contains alid 2301,base 2302, and for waterproof versions, awaterproof seal 2320 located between the two. Thelid 2301 is connected tobase 2302 via ahinge 2310. Alatch mechanism 2312 may be provided to secure thelid 2301 to thebase 2302 so as to form a waterproof seal there between. Thedisplay screen 2352 can be viewed through adisplay window 2303 in the lid. The touchsensitive control 2351 of theelectronic audio device 2350 is controlled through thelid 2301 using arotating control mechanism 2400. For capacitive touch sensitive controls, therotating control mechanism 2400 may include conductive materials to transmit charge to the proximity of the control. For pressure sensitive controls, therotating control mechanism 2400 need not include conductive materials. - On the inside of the
lid 2301, therotating control mechanism 2400 contains anarm 2408 coupled to a touch sensitive surface actuating member, such as touchwheel contact pad 2423 for contacting thetouch control 2351. For capacitive controls, thearm 2408 andcontact pad 2423 may be conductive. As thecontrol mechanism 2400 is rotated, thearm 2408 rotates, moving thecontact pad 2423 over the touchsensitive control 2351 on theelectronic audio device 2350. In some embodiments, the shape and size of thepad 2423 may approximate the contact surface of a finger touching thecontrol 2351. For example, thepad 2423 may be a metallic disk approximately 1 cm in diameter. In other embodiments,pad 2423 may be selective conductive plastics or a combination of materials that hold and transmit a charge, such as an electroplated plastic material. In embodiments where thetouch control 2351 is pressure sensitive, non-conductive materials such as non-conductive plastics may be used forpad 2423. - In some embodiments where the electronic device contains a capacitive control feature, the touch sensitive surface actuating member such as
pad 2423 may be positioned close to the touchsensitive control 2351, but not in physical contact with the touchsensitive control 2351. The charge provided by the touch sensitive surface actuating member (e.g., pad 2423) may be developed so that a predetermined proximity, such as 0.1 mm, 0.5 mm, 1 mm, or more will allow the touchsensitive control 2351 to react to the motion of the touch sensitive surface actuating member. In some embodiments, this distance may be variable, and controlled by the user from outside thehousing lid 2301 or thehousing base 2302. In some embodiments, a thin non-conductive material, such as an adhesive tape, may be placed over the touch sensitive surface actuating member (e.g., pad 2423) so as to electrically insulate the touch sensitive surface actuating member from the touchsensitive control 2351. A change in charge on the touch sensitive surface actuating member can then be detected by the touchsensitive control 2351 by detecting the change in capacitance between thecontrol feature 2351 and the touch sensitive surface actuating member, provided the non-conductive material in between is not too thick. Other methods for adjusting the charge of the touch sensitive surface actuating member include selecting materials in theconductive wheel assembly 2402 that hold the desired charge amount to activate thecontrol 2351 and utilizing batteries or other portable power sources in the assembly. - On the outside of the lid, the
control mechanism 2400 contains arotatable wheel 2402 configured such that the user can rotate thewheel 2402 with a finger. For capacitive controls, therotatable wheel 2402 may include conductive material that is electrically connected to thearm 2408. Electric charge can then be conducted from the user's finger, through theconductive rotatable wheel 2402, through thecontrol mechanism 2400, and into the touch sensitive surface actuating member (e.g., pad 2423). Accordingly, the change in the charge caused by contact of the user's finger can be sensed by the touchsensitive control 2351. In some embodiments, the rotatableconductive wheel 2402 comprises a feature such as anindentation 2360 for interfacing with a user's finger to facilitate the user rotating thewheel 2402. In some embodiments, a non-conductive mask is provided that covers all portions of thewheel 2402 except theindentation 2360 to minimize the chance of false sensing by the touchsensitive control feature 2351 on theelectronic audio device 2350. - In embodiments where the touch
sensitive control feature 2351 is pressure sensitive, the touch sensitive surface actuating member (e.g., pad 2423) may provide the required amount of pressure against thecontrol feature 2351 such that as therotatable wheel 2402 is rotated, movement of the touch sensitive surface actuating member over thecontrol feature 2351 simulates the pressure of a human finger moving over thecontrol feature 2351. In some embodiments, the touch sensitive surface actuating member may only transmit pressure to thecontrol feature 2351 when downward pressure is applied by a user to therotatable wheel 2402. - In some embodiments, the
audio device 2350 may feature atouch wheel 2351 that additionally allows for activation by pressing pushbuttons at various locations about thewheel 2351. The pushbuttons may be activated through the housing using pushbutton assemblies. Additionally, a central button control mechanism may be provided for controlling abutton 2353 in the middle of thewheel 2351 on theelectronic audio device 2350. Thecentral button 2353 on theelectronic audio device 2350 may either be a capacitive touch sensitive button or a push button. On the inside of the lid, the push button assemblies comprisebutton contact pads 2415 for pressing the buttons on theelectronic audio device 2350. On the outside of the lid, the push button assemblies containfinger pads 2411 for a user's finger to press the assemblies. In one embodiment, the pads are constructed of non-conductive plastic. When thecentral button 2353 on theelectronic audio device 2350 is a capacitive touch sensitive button, the centralbutton control mechanism 2350 may contain conductive elements for transferring charge from the user's finger. Themechanism 2350 may be configured such that electrical contact between the finger pad and the button contact pad is only made when the finger pad is pressed by the user. - The housing may also features an audio communication link such as described above with respect to
FIGS. 22A, 22B , and 22C including afastener 2308 to provide a waterproof connection with earphones or speakers. In some configurations, a wireless transmitter may be used for transmitting the signal to earphones or speakers. - One embodiment of the
rotatable control mechanism 2400 is shown in exploded view inFIG. 24 . In one embodiment, therotatable control mechanism 2400 consists of anon-conductive mask 2401 affixed about aconductive wheel 2402. Themask 2401 contains one ormore apertures 2460 for allowing a user's finger to contact thewheel 2402. Themask 2401 prevents the dielectric charge of water particles from inadvertently activating the controls of theaudio device 2350 by transferring a charge to the capacitivesensitive surface 2351 of the electronic audio device. Furthermore, themask 2401 reduces accidental contact of theconductive wheel 2402 when thecentral button assembly 2410 is pressed. In other embodiments, nomask 2401 is provided. Thewheel 2402 is seated atop an o-ring seal 2403 to prevent fluids from passing into the opening of the housing. The center of therotatable control mechanism 2400 features apushbutton assembly 2410 that consists of abutton finger pad 2411, apushbutton spring 2412, ashaft 2413 for transferring vertical force through the housing tobutton contact pad 2415, which is held toshaft 2413 usingfastener 2416. There is also ashaft seal 2414 to prevent water flowing in the cavity of the housing through the hole inlid 2301 for thebutton assembly 2410.Wheel 2402 is connected throughhousing lid 2301 to awheel arm 2408 using a clamping device that protectslid 2301 from water ingress using o-ring 2406 held in place bywashers Wheel arm 2408 connects to an assembly that features afastener 2421, aspring 2422, and atouch pad 2423. Thespring 2422 presses thetouch pad 2423 against the touchsensitive control feature 2351 on theelectronic audio device 2350. In some embodiments, a thin non-conductive material is coated on the bottom of thetouch pad 2423. While these components effectively comprise a conductive scroll wheel assembly, one skilled in the art can find an alternate assembly of parts to generate the same effect. This rotatable assembly can be made entirely of electrically conductive parts, such as, but not limited to, metals, conductive plastics, metal coated plastics, co-molded assemblies, ceramics, and other conductive materials convenient for the manufacture of components. In alternative embodiments, devices that hold charge, such as a capacitor or battery, may be used in conjunction with the assembly to generate a positive or negative charge on the assembly in order to enhance the change in capacitance sensed by the touch wheel. - Although circular control features have been described, it will be appreciated that other shapes are also possible. For example, in some embodiments, a control mechanism is provided that allows a user to move a touch sensitive surface actuating member (e.g., pad 2423) in unrestricted directions over a touch sensitive control surface.
- Although an electronic audio device has been described having a separate touch
sensitive control feature 2351 anddisplay screen 2352, it will be appreciated that other configurations are possible. For example, in some embodiments, thedisplay screen 2352 itself is touch sensitive. In such embodiments, control mechanisms may be provided to position and maneuver a control pad (e.g., pad 2351) over thedisplay screen 2352. In some of these embodiments, the control pad and other control features may be constructed of a transparent material so as to permit unobstructed viewing of the display screen. In some embodiments, the touch sensitive surface actuating member is positioned such that it does not directly contact the screen, for example, as described above, so as to prevent scratching of the screen. - The control mechanisms described above for use with touch sensitive controls may be used in any protective housings for electronic audio devices. For example, the mechanisms may be incorporated into a waterproof housing. The rigid control mechanisms may prevent the device control features from activating as a result of underwater pressures. The mechanisms may also be incorporated into water resistant and/or shock or impact resistant housings. For example, rugged housings designed to withstand mechanical shock and stress may be provided that are not waterproof The rigid control mechanisms described herein provide protection of the audio device in such environments. The protective housing may also be designed to protect against dust, dirt, heat, cold, or other harsh environments.
- Other control features that can be manipulated using mechanisms described herein include but are not limited to buttons, levers, switches, capacitive touch screens, capacitive surfaces, slides, latches, joysticks, and button pads.
- In one embodiment, a set of waterproof headphones are provided for use in conjunction with any of the housings described above. In particular, the headphones depicted in
FIG. 25 may be configured to connect to the housings depicted inFIGS. 21A and B and 23A andB. Headphones 2500 features left channelwaterproof speaker assembly 2550 and right channelwaterproof speaker assembly 2551, which transmit audio signals into the left and/or right ear canals of the user. Theleft speaker assembly 2550 is held in place on the left ear using anear clip frame 2503, while theright speaker assembly 2551 is held on using rightear clip frame 2504. These ear clip frames provide added stability for the user to maintain correct positioning of the speakers in the ears during active water sports. Additionally a tension providingneck frame 2505 secures the ear clips 2503 and 2504 by connecting them around the head of the user. As shown,neck frame 2505 wraps around the base of the skull of a user which is optimal for securing the headset on the user during water sports, particularly when water flows over the head of the user.Neck frame 2505 also provides a mechanism forspeaker wire 2506 to connect towaterproof speaker assemblies speaker wire 2506 is split into the left channel and right channel signals at the base of theneck frame 2505.Speaker wire 2506 features a strain relief area that leads to a maleelectrical connector 2509, such as a 3.5 mm stereo plug, found commonly on portable audio devices. One method of providing a waterproof environment for the electrical connection between the audio device and thewaterproof speaker connector 2509, is to use a flexible overmold assembly 2510 that attaches tofastener mold 2510 securing to the outside of the fastener of the audio communication link of the housing. Those will skill in the art will recognize that this design may alternatively provide a waterproof connection using internal features of a fastener. - While the speaker headset described above uses electrically conductive wires for the transmission of audio output, there may be configurations where the audio communication link is wireless. Such wireless systems are described in more detail in U.S. application Ser. No. 11/123,878, filed on May 6, 2005, which is incorporated herein by reference in its entirety and specifically for the purpose of describing systems and methods for providing audio to the ears of a user in an aquatic environment using wireless transmission of signals to headphones.
- Embodiments of the present invention have been shown and described with a degree of particularity to enable their complete and full understanding. It should be understood, however, that the present invention embodies the inventive concepts as defined by the claims, and is not limited by any detailed description herein.
