Description

CLOSEABLE RADIO COMMUNICATIONS DEVICE AND METHOD THEREREOF
FIELD OF THE INVENTION
This invention relates a closeable communications device with a two part housing movable from a closed to an opened position. The invention is particularly useful for, but not necessarily limited to, selective activation and deactivation of outer and inner audio transducers of closeable communications devices depending of whether or not the device's housing is in the closed or opened position.
BACKGROUND OF THE INVENTION
Communication devices, such as radio or cellular telephones, that are easy to transport and support desirable features are becoming commonplace. One communication device that is easy to transport is a closeable cellular telephone having a two part housing movable from an opened position to a closed position and vice versa. In the opened position, a conventional cellular telephone user interface includes a speaker, a microphone, a display, and a keypad, that are fully exposed. Also, the cellular telephone has a length that is sufficient to allow the ear and mouth of the user to align with the speaker and microphone, respectively.
In the closed position the cellular telephone is shorter in length. Also, when most closable cellular telephones are in the closed position either the speaker or microphone or both the speaker and microphone are audibly inaccessible and inoperable. Hence, when a user wishes to make a typical call, they first adjust the telephone to the opened position so that the required speaker and microphone (audio transducers) are both audibly accessible and operable. This may be inconvenient and thus closeable telephones have been proposed that have a microphone and speaker operable when in the closed position and they do not necessarily require the telephone housing to be opened when dialling a number and making a call. However, it would be useful to have a closeable telephone that can maintain a communications call whilst a user moves or flips the housing between the opened and closed position, or vice versa, and selectively activate and inactivate the audio transducers.
In this specification, including the claims, the terms 'comprises', 'comprising' or similar terms are intended to mean a non-exclusive inclusion, such that a method or apparatus that comprises a list of elements does not include those elements solely, but may well include other elements not listed. Also, the terms inactivating and inoperable have the same meaning and can be used interchangeably throughout this specification. Similarly, the terms activating and operable have the same meaning and can be used interchangeably throughout this specification

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE
INVENTION
In the drawings, like numerals on different Figs are used to indicate like elements throughout. With reference to Fig. 1, there is illustrated a closeable radio communications device 1 comprising a radio frequency communications unit 2 coupled to be in communication with a processor 3. The device 1 also has an outer user interface 5a with a screen 5c and a keypad 5b and an inner user interface 6a with a screen 6c and a keypad 6b. The respective screens 5c, 6c and keypads 5b, 6b of interfaces 5a, 6a are coupled to be in communication with the processor 3. Also, as will be apparent to a person skilled in the art screens 5c, 6c may be touch screens thereby making the keypads 5b, 6b optional. A housing position detector 19 is also coupled to the processor 3 to provide one or more housing position signals (PS) , the position detector 19 typically being a mechanically actuated push button switch, however, the position detector 19 can comprise any suitable detector such as a magnetic sensor (reed switch) , a capacitance sensor, an inductance sensors, a potentiometer or a photo sensor.
The processor 3 includes an encoder/decoder 11 with an associated Read Only Memory (ROM) 12 storing data for encoding and decoding voice or other signals that may be transmitted or received by the device 1. The processor 3 also includes a micro-processor 13 coupled, by a common data and address bus
17, to the encoder/decoder 11, a character Read Only Memory
(ROM) 14, a Random Access Memory (RAM) 4, static programmable memory 16 and a SIM module 18 for operatively coupling to a removable Subscriber Identity Module (SIM) card. The static programmable memory 16 and SIM module 18 when coupled to a SIM card each can store, amongst other things, selected incoming text messages and a Telephone Number Database TND (phonebook) comprising a number field for telephone numbers and name field for identifiers associated with one the numbers in the name field. For instance, one entry in the Telephone Number
Database TND may be 91999111111 (entered in the number field) with an associated identifier xvSteven C at work" in the name field.
The micro-processor 13 has ports for coupling to the interfaces 5a, 5b, and an alert module 15 that typically contains a speaker, vibrator motor and associated drivers. Also, micro-processor 13 has ports for coupling to two outer audio transducers in the form of an outer microphone 5e and an outer speaker 5d; and two inner audio transducers in the form of an inner microphone 6e and an inner speaker 6d. The character Read only memory 14 stores code for decoding or encoding text messages that may be received by the communication unit 2. In this embodiment the character Read Only Memory 14 also stores operating code (OC) for micro¬ processor 13 and code for performing functions associated with the device 1.
The radio frequency communications unit 2 is a combined receiver and transmitter having a common antenna 7. The communications unit 2 has a transceiver 8 coupled to antenna 7 via a radio frequency amplifier 9. The transceiver 8 is also coupled to a combined modulator/demodulator 10 that couples the communications unit 2 to the processor 3.
Referring to Figs. 2 and 3 there is illustrated a first embodiment of the closeable radio communications device 1 that has a housing 21 with two portions 22, 23 movably mounted to each other to allow relative movement of the portions 22,23 between a closed position of Fig 2 and an opened position of Fig 3. Disposed, or partially disposed, in the housing 21 are the components of Fig.l including the transceiver 8 and processor 3.
The relative movement, as shown in this embodiment, is achieved by the portions 22,23 being pivotally mounted to each other about a pivotal axis A. In the closed position of Fig 2 the outer user interface 5a of the screen 5c and the keypad 5b are visible and accessible by a user, the screen 5c and a keypad 5b being disposed in portion 22. Also, the outer microphone 5e and outer speaker 5d are audibly accessible and operable when the housing 21 is in the closed position. In contrast, the inner user interface 6a of the screen 6c and the keypad 6b are totally hidden (sandwiched between portions 22,23) when the housing 21 is in the closed position; and the two inner audio transducers namely the inner microphone 6e and inner speaker 6d are audibly inaccessible (sandwiched between portions 22,23) and inoperable when the housing 21 is in the closed position.
In other embodiments the inner user interface 6a may be only partially hidden or partially accessible when the housing 21 is in the closed position. Also, as clearly shown in Fig. 2 the closeable radio communications device 1 has a protrusion 24, on the housing 21, for co-acting with the housing position detector 19 to generate the position signal (PS) when the housing 21 is moved to the opened position as shown in Fig. 3. Shown in the opened position of Fig. 3 is the inner user interface 6a of the screen 6c and the keypad 6b that are accessible and visible. Furthermore, the two inner audio transducers namely the inner microphone 6e and inner speaker 6d are audibly accessible and operable when the housing 21 is in the opened position. In addition, the protrusion 24 is shown co-acting with the housing position detector 19 thereby generating the position signal (PS) sent to microprocessor 13 that results in the inner microphone 6e and inner speaker 6d becoming operable and the two outer audio transducers, namely outer microphone 6e and outer speaker 6d, becoming inoperable when the housing 21 is moved to the opened position.
As shown in Figs 2 and 3, the inner microphone 6e is mounted in one of the two portions 23 and the inner speaker 6d is mounted in the other one of the two portions 22. Also, outer microphone 5e and the outer speaker 5d are mounted on the same one of the two portions 22. In use, when the housing 21 is in the closed position a user can initiate an outgoing communication call through the transceiver 8 by actuation of the outer user interface 5a. In addition during the communication call, when the housing is in the closed position, the outer speaker 5d and outer microphone 5e are operable. In this regard, the speaker 5d and outer microphone 5e may operate as a hands-free speakerphone in which a user may place the device 1 on a table or desk whilst communicating in the call via the speaker 5d and outer microphone 5e.
Referring to Figs 4 and 5 there is illustrated a second embodiment of the closeable radio communications device 1 that has a housing 41 with two portions 42, 43 movably mounted to each other to allow relative movement of the portions 42,43 between the closed position of Fig 4 and the opened position of Fig 5. The relative movement, as shown in this embodiment, is achieved by the portions 42,43 being pivotally mounted about a pivotal axis. In the closed position of Fig 4 an outer user interface 45a (in the form of a keypad) is visible and accessible by a user, and is disposed in portion 42. Also, an outer speaker 45d and outer microphone 45e are audibly accessible and operable when the housing 41 is in the closed position. In contrast, an inner user interface 46a (in the form of a touch screen) is viewable through a screen 48 but not physically accessible when the housing 41 is in the closed position. In addition, an inner speaker 46d is audibly inaccessible (sandwiched between portions 42,43) and inoperable when the housing 41 is in the closed position. Also, as clearly shown in Fig. 5 housing position detector 19 is mounted in portion 43 and as will be apparent to a person skilled in the art, generates the position signal (PS) when the housing 41 is moved from the closed position.
As illustrated, the outer microphone 45e is mounted in one of the two portions 43 and the outer speaker 45d is mounted in the other one of the two portions 42. As shown in the opened position of Fig. 5 is the inner user interface 46a in the form of a touch screen that is accessible and completely visible. Furtheremore, the outer microphone 45e and inner speaker 46d are audibly accessible and operable when the housing 21 is in the opened position and the and outer speaker 45d being inoperable when the housing 21 is moved to the opened position.
Referring to Figs 6 and 7 there is illustrated a third embodiment of the closeable radio communications device 1 that has a housing 61 with two portions 62, 63 movably mounted to each other to allow relative movement of the portions 62,63 between the closed position of Fig 6 and the opened position of Fig 7. The relative movement, as shown in this embodiment, is achieved by the portions 62,63 being pivotally mounted about a pivotal axis. In the closed position of Fig 6 an outer user interface 65a (in the form of a keypad) is visible and accessible by a user, and is disposed in portion 62. Also, an outer speaker 65d and outer microphone 65e are audibly accessible and operable when the housing 61 is in the closed position. In contrast, an inner user interface 66a (in the form of a touch screen) is viewable through a screen 68 but not physically accessible when the housing 61 is in the closed position. In addition, an inner speaker 66d is audibly inaccessible and inoperable when the housing 61 is in the closed position. Also, as clearly shown in Fig. 7 housing position detector 19 is mounted in portion 63 and generates the position signal (PS) when the housing 61 is moved from the closed position toward the opened position.
As illustrated, the outer microphone 65e and the outer speaker 65d are mounted in the same portion 63. As shown in the opened position of Fig. 7 is the inner user interface 66a in the form of a touch screen that is accessible and completely visible. Furthermore, the outer microphone 65e and inner speaker 66d are audibly accessible and operable when the housing 21 is in the opened position and the outer speaker 65d being inoperable when the housing 21 is moved to the opened position.
Referring to Figs 8 and 9 there is illustrated a fourth embodiment of the closeable radio communications device 1 that has a housing 81 with two portions 82, 83 movably mounted to each other to allow relative movement of the portions 82,83 between the closed position of Fig 8 and the opened position of Fig 9. The relative movement, as shown in this embodiment, is achieved by the portions 82,83 being pivotally mounted about a pivotal axis. In the closed position of Fig 8 an outer user interface 85a (in the form of a keypad) is visible and accessible by a user, and is disposed in portion 82. Also, an outer speaker 85d and outer microphone 85e are audibly accessible and operable when the housing 81 is in the closed position. In contrast, an inner user interface 86a (in the form of a touch screen) is viewable through a screen 88 but not physically accessible when the housing 81 is in the closed position. In addition, an inner microphone 86e is audibly inaccessible and inoperable when the housing 81 is in the closed position. Also, as clearly shown in Fig. 9 housing position detector 19 is mounted in portion 83 and generates the position signal (PS) when the housing 81 is moved from the closed position toward the opened position.
As illustrated, the outer microphone 85e and the outer speaker 85d are mounted in the same portion 83. As shown in the opened position of Fig. 9 is the inner user interface 86a in the form of a touch screen that is accessible and completely visible. Also, the outer speaker 85d and inner microphone 86e are audibly accessible and operable when the housing 21 is in the opened position and the outer microphone 85e being inoperable when the housing 21 is moved to the opened position. In Fig. 10 there is illustrated a method 100 for selective operation of the audio transducers of a closeable radio communications device 1. The method 100 provides for selective operation of audio transducers such a the outer speaker 5d, outer microphone 5e, inner speaker 6d and inner microphone 6e. The method 100 includes effecting 105 a communications call through a transceiver 8 of the device 1. This communications call (communication) is effected by suitable actuation of either of the user interfaces 5a or 6a depending on an initial position of the housing 21 (e.g. depending on whether the housing is in the opened or closed position) . Such a communications call can be effected by dialling a telephone number whilst the housing 21 is in the closed or opened position. Also, the communications call can be effected by accepting an incoming call whilst the housing 21 is in the closed or opened position.
Next a detecting test 110 provides for detecting movement of the two portions 22,23 between the closed position and the opened position. If the detecting test 110 detects, by reading the positions signals (PS) from the position detector 19, that the housing 21 moves from the closed to the opened position then a selectively inactivating step 115 provides for selectively inactivating operation of at least one of the audio transducers. More specifically, the selectively inactivating step 115 provides for selectively inactivating at least one of the outer audio transducers, typically the outer speaker 5d when the detecting determines the movement of the two portions 22,23 between the closed position to the opened position. However, both the outer speaker 5d and outer microphone 5e can be inactivated at step
115. Next, at a selectively activating step 120 provides for selectively activating operation of at least one of the transducers when the detecting 110 determines the movement of the two portions 22,23 between the closed position to the opened position. Again more specifically, the selectively activating step 120 provides for selectively activating at least one of the inner audio transducers, typically the inner speaker 6d. However, both, or either, the inner speaker 6d and inner microphone 6e can be inactivated at step 115.
If at the detecting test 110, by reading the positions signals (PS) from the position detector 19, it is determined that the housing 21 has moved to the closed position then a selectively inactivating step 125 provides for selectively inactivating operation of at least one of the audio transducers. This detecting test 110 again determines the movement of the two portions 22,23 between the opened position to the closed position or vice versa. The selectively inactivating step 125 provides for selectively inactivating at least one of the inner audio transducers, typically the inner speaker 6d. However, both the inner speaker 6d and inner microphone 6e can be inactivated at step 125.
Next, a selectively activating step 130 provides for selectively activating operation of at least one of the transducers when the detecting 110 determines the movement of the two portions 22,23 between the opened position to the closed position. The selectively activating step 130 provides for selectively activating at least one of the outer audio transducers, typically the outer speaker 6d. However, both, or either, the inner speaker 5d and inner microphone 5e can be inactivated at step 125. After either steps 120 or 130 a test 140 is effected to determine if the communications call has ended. If the call has ended then the method 100 terminates at an end step 150.
Alternatively, if the call is still in progress then the method returns to the detecting test 110.
Advantageously, the present invention provides selectively inactivating and activating audio transducers during a communication call. In his regard, the outer audio transducers are operable when the housing is in the closed position and when the housing is moved to the opened position at least one of the outer audio transducers becomes inoperable. Typically, the invention provides for selectively inactivating the outer speaker so that privacy of a call can be effected so that the outer speaker (perhaps performing as a speakerphone speaker) does not emit part of a communications call. Thus, it will be apparent to a person skilled in the art that a communications call can be maintained whilst a user can flip the housing 21 between the opened and closed position, and vice versa, to selectively activate and inactivate the audio transducers. For instance, when in the closed position the device operates in a similar manner to a candy bar telephone during a communications call and when the sensor 19 detects that the housing 21 moves to the opened position the communications calls continues and selective inactivation of at least one outer audio transducer and selective activation of at least one inner audio transducer typically results. Also, if the housing is in the closed position and the device 100 receives an incoming call, a user can quickly answer the call by actuating the outer user interface 5a and effect communications through the outer audio transducers. This feature can be advantageous when a user cannot readily or immediately move the device 100 to the opened position to effect communications or use an earpiece accessory.
The detailed description provides preferred exemplary embodiments only, and is not intended to limit the scope, applicability, or configuration of the invention. Rather, the detailed description of the preferred exemplary embodiments provides those skilled in the art with an enabling description for implementing preferred exemplary embodiments of the invention. It should be understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the invention as set forth in the appended claims. For instance, although a clamshell type device has been illustrated, other closeable devices may be used such as flip telephones or rotatable two part telephones typical examples of which are the Motorola™ V70™ and V80™ cellphones.
