FIELD OF INVENTION

This invention relates to a smart musical instrument and smart singing system coupling music equipment, singing, and a computer. More particularly, this invention relates to a system wherein musical instruments and singers communicate wirelessly to a computer and thereby, if desired, to a remote participant or group via the internet.

BACKGROUND OF THE INVENTION

A number of patented drum and singing devices embody sensing components and software. Typically, these devices display music information that relates to drummer's stroke, and singing style. The information is displayed or signaled by the drum and smart singing systems or simulations of drum and smart singing systems via interactive software and electronics. None of these cooperates with drum strokes and singing styles that sense each actual drum stroke or strokes and singing styles for local and or remote interactive drum and singing musical interaction.
It is desirable to remotely communicate the actual performance location and music of the singing musician, whereby more sophisticated analysis and prediction possibilities are realizable via computer technology and state-of-the-art display music techniques. Further, it is also desirable to use such performance information in an expanded capacity to provide interactive music and singing competition amongst numerous music and singing musicians in locations remote from each other.

SUMMARY OF INVENTION

This invention relates to a system that interconnects real music musical instruments or other music instruments and or singers to a computer. In a preferred embodiment the computer is coupled wirelessly to one or more musical instruments and singers. Further, the invention, summarized below, allows one or more musicians and singers to enter into a competition against each other. Each musician and or singer logs-in to ask the computer who is available to practice or play music in a musical and or singing contest. Once a musician and or singer pairs up against another musician and or singer anywhere in the world and musical play and or singers sing and play ensues, the computer and display show each musical and singing participant's score via animation or graphics that preferably relate to a musician's and singer's individual performance statistics. A single singer and or musician may practice singing, or play music without a musician or singing opponent and improve basic musical rhythm and singing skills using the computer and music to track their performance. The system application is unlimited and much of this system can be used not only for music and singing competition on the Internet, but for other musical instruments and singers as well. Musical implements and singers with sensors attached according to this invention are used for training purposes, for interactive musical and singing internet competition. The technology can be used for training, competition, and the improvement of music response related reflexes and coordination. With little or no modification, the technology also has applications in medicine, particularly musical physical therapy.

1. Smart Drum Instrument

A wireless drum instrument is constructed to contain or alternatively, a standard drum instrument is modified to contain, a multiple drum triggers, sensors or transducer array located on the drum head or face or hitting surface. Upon impact of the head of the drum with a drum stick the impacted sensors produce detectable variances representing the magnitude and duration of the drum-drum stick impact force and the proximate location of such contact relative to the preferred location, on the face of the drum head. The variances are electronically processed into digitally coded information and remotely transmitted by an electrical communication circuit either contained within or attached to the drum head or face.
In each of the drum instrument device according to this invention, in a preferred embodiment the transducer are or include piezoactive elements and or drum triggers. As used herein “piezoactive” includes piezoelectric and piezoresistive components. Piezoactive components are defined as components the electrical properties of which, when the component is subjected to physical force, vary. A drum trigger converts energy produced by stick attack into electrical impulses. The impulses are then supplied to the drum module (brain of the system).
The smart drum instrument system uses biofeedback to create an intelligent drum training and entertainment system. The smart drum instrument system is a diagnostic and analysis tool used to improve a drummers skills by instantaneous by visual and acoustic feedback and cue's with little or no human intervention. The smart drum instrument system takes the generated data and reconstructs it into a useful visual format which can be presented in a variety of ways including 3-dimensional animation. The smart drum instrument system integrated circuit or circuits can be designed anywhere within the drum including the head and or drum stick.
The smart drum instruments has the means via its built in microcontroller to process, analyze, store, stick hitting pattern data and transmit it to the computer and or the Internet for further analysis. In playback mode the smart drum instrument system memorizes how many times each sensor was hit. This allows the drummer to know his or her hitting pattern. Using a computer algorithm, we can analyze and calculate a drum stroke pattern and having a musical personalized drum hitting detection system for each musician.

2. Smart Singing System

A smart singing system has a microphone attached or is detachable to a singer. The smart microphone can be held in the hand of a singer or worn on the singer's chess area. The smart microphone that is hand held or worn on the singer has a transducer built-in, when touched by the singer or impacted by the singer's hand, the sensor produces a detectable variance representing impact with the hand. The variance is electronically processed into display coded information and remotely transmitted by an electrical communication circuit. In one preferred embodiment the communication circuit is contained within the smart microphone. Preferably, the communication circuit for the smart microphone is located inside the stem.
The singing system uses biofeedback to create an intelligent sing training entertainment system. The smart singing system is a diagnostic and analysis tool used to improve a singer's skills by visual and acoustic feedback cues with little or no human intervention. The singing system takes the generated data and reconstructs it into a useful visual format which can be presented in a variety of ways including 3-dimensional animation.
In each of the drum set device and smart microphone device according to this invention, in a preferred embodiment the transducers are or include piezoactive elements. As used herein, “piezoactive” includes piezoelectric and piezoresistive components. Piezoactive components are defined as components the electrical properties of which, when the component is subjected to physical force, vary.

3. Wireless Signal Receiver and Computer

At each remote player site, wireless radio frequency equipment receives the digitally coded transmitted signals from the drum set, the microphone, and the drum swing motion sensing device and audio feedback. The signals are demodulated and processed into serial binary data suitable for communications to the computer via either serial or parallel ports. As the game progresses, the computer under the control of the musical software, monitors and directs the flow of communications between the musicians and singers via the internet and displays the music and singing game simulations and performance information.

4. Computer Drumming Software System

At each remote player site, a computer under the control of the drumming and singing software, monitors and controls the sequential play of the musical and singing game and interacts with the musical game and or singing player game at the site and also competing musical and singing players at the other remote sites via the internet. The software system generates the musical and singing game simulations for display and tracks each musical player's and singing player's performance as the musical and or singing game progresses.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

As shown in FIG. 1, a preferred embodiment of the invention includes a wireless smart drum system 20, a wireless audio detection system 22, a wireless drum motion sensing plate 24, a wireless receiver 26 connected to a computer 28, and a display or monitor 30 with speakers 31 operated under the control of drum system software 32, and connected via the internet to an internet drum game server 34 (called herein the GGC server)

1. Smart Drum System

The smart drum system 20 has a head 40 and a stick 42. As shown in FIGS. 2 and 3, the head 40 has a drum stick opening 42, a plurality of embedded contact sensors 46 (three are illustrated in the preferred embodiment), and the internal electronics circuitry 48 including a wireless radio frequency transmitter (58 in FIG. 5). As shown, at least one of the sensors 46 is located at or proximate to the optimal location on a drum face 47 for contact with the drum stick. The contact sensors may be, but are not limited to sensors employing piezoactive type transducers or drum triggers, specifically, either piezo-electric or piezo-resistive transducers (similar, but is not limited to the Cooper Instruments LPM 562).
In an alternative embodiment, FIG. 2, three sensors 46 are applied to the face of an adapted drum by a mylar tape or other means 49. Again, the electronic circuitry is internal to the drum head 40 and connects to the sensors 46 by leads 27.
In a second alternative embodiment, to retrofit a standard drum, contact sensors 46 are part of an adapter 40 attached to an ordinary drum head as seen in FIG. 4 and wire connected to an electronic circuitry 48 attached to the drum stick 42 or elsewhere on the drum. A drum stick contacting any sensor 46 produces a detectable variance indication the magnitude and duration of sensor-ball impact. The variance may be a change in resistance of a piezo-resistive transducer or a voltage change in the case of a piezo-electric transducer. As shown in FIG. 5, the variance is detected and amplified by an associated amplifier 52 and is the input to an associated integration circuit 54, the output of which represents the energy of the ball-drum contact event. Connected to the integration circuit 54, a microprocessor 56 is a multi-input signal processing circuit (similar, but not limited to a Motorola #68HCO5) having analog to digital signal converting circuits (ADCs), one for each input channel, and a sequential digital signal encoding circuit connected so as to convert the ADC outputs into a time multiplexed serial digital data stream containing a binary-coded word for each channel indicating the energy of the associated sensor-ball impact event.
A radio frequency transmitting circuit 58 receives the serial digital data from the microprocessor 56 and wirelessly transmits the information via an internal antenna 60 to a receiver 26 (FIG. 1) for subsequent processing by the computer 28. Using programming as contained in the accompanying microfiche appendix, one skilled in the art can readily accomplish the game programming described. Alternative programming too will be apparent from the foregoing functional description and the illustrations contained in the appended drawings.

2. Smart Microphone

The smart microphone uses 22 in FIG. 1, to allow voice inputs, as shown in FIG. 3. The smart microphone has a contact sensor pad 64, shown in FIG. 6, containing at least one contact sensor (three different activation areas 65, 66, and 67 are illustrated in the preferred embodiment). The internal circuitry includes a wireless radio frequency transmitter (as shown in FIG. 5). Additional sensor activation area 65 and 67 are adjacent, one on either side of the center area 66. In the preferred embodiment of FIGS. 1, 2, and 3, and like the sensor used at the face of the drum and smart microphone, the sensors may be, but are not limited to, sensors employing piezo-active type transducers, specifically, either piezo-electric or piezo-transducers.
A hand touching the smart microphone 60 and containing the sensor pad 65, 66, or 67 produces a detectable variance indicating the hand-sensor smart microphone event. The variance may be a change in resistance in the case of a piezo-resistive transducer (similar, but not limited to Cooper Instruments LPM 562) or a voltage change in the case of a piezo-electric transducer. As illustrated in FIG. 7, the variance is detected and amplified by an associated amplifier 71. The amplified signal then is input to a microprocessor 72 having an analog to digital signal converting circuit (ADC) and a digital signal encoding circuit connected so as to convert the ADC output representing the sensors signals into a serial digital data stream containing a binary coded word indicating the sensor-hand contact event. The microprocessor 72 may be the same or similar to the microprocessor 56 of the drum system electronics.
A radio frequency transmitter circuit 74 receives the serial digital data from the microprocessor 72 and wirelessly transmits the information via an internal antenna 76 to the receiver 26 (FIG. 1) for subsequent processing by the computer 28. The smart microphone configuration is susceptible to much variation. The smart microphone illustrated and described above is well suited to indoor use, on carpet for example.

3. Wireless Signal Receiver and Computer

At each player site, a wireless radio frequency signal receiver 26 is connected to the computer 28 by either the serial (USB) or parallel computer ports, as shown in the functional block diagram, FIG. 8. The wireless signal receiver 26 detects digitally coded radio frequency transmissions from the communication circuit associated with any of a smart drum system 20, a smart microphone 22, as shown in FIG. 1. The received transmission are demodulated by the RF receiver circuitry 122 (FIG. 10) connected to a microprocessor 124, which converts the demodulated data signal to serial binary coded data suitable for communications to a computer 28. The computer 28, under the control of the internally installed golf system software program, monitors and directs the flow of communications between remotely located players via the internet and displays the game simulations and performance information. In appropriate installations the wireless electromagnetic signals that communicate with the receiver may be infrared communications.

5. Computer Drumming Software

At each remote player site, the computer 28 (FIG. 1) under the control of the drumming software program (shown in the drumming software system functional block diagram, FIG. 9) monitors and control initialization and the sequential play of the drumming and singing game, or alternatively, the individual musician and or singer player practice session. Upon start up by a musician and or singer player at a particular site, the system input parameters are set and the system internet and music and or singer player port interfaces are initialized 130 as indicated by the arrows 130 a and 130 b. For internet communications, the serial port listener of the computer 28 is enabled in the preferred embodiment. A remote player event listener is initialized. It will communicate events from one or more of the smart drum system, the smart microphone and the motion sensor plate. The main operational software (program) thread is run 130, and the system awaits data input from the appropriate computer communications ports at 132 (port), 133 (Remote player Socket Event Listener).
If the competitive play mode has been selected, the program generates a player participation request and sends 134 the request to the GGC game internet server (GGC server) 34 (FIG. 1). Upon identification of a player opponent at 150 (FIG. 12) by the GGC server, the program initiates the player identification sequence 152 and sequential play begins 154 (This software sequence and control routine occurs at each remote site where play has been initiated. During the game play sequences 154, the program generates the appropriate animation, display, and audio data and commands 136 and 138 (FIG. 9), and communicates with the associated display and speaker devices 30 and 31 (FIG. 1). Upon the occurrence of a local player event, detected at 133, the main operating program at 130, displays the event at 136, and communicates the event at 132 by causing a device transmission at 137 to be send at 134 via the internet GGC server 135 which displays the event for the opposing player and alerts the opposing player it is his/her turn to play. The local player event may be, but is not limited to the smart drum system impacting a ball, the swing of a club across the sensing plate or the balls entry into the receptacle. The program contains time delay limits for the player action, and delays of play beyond these limits generate play quit and disconnect signals. The event at 133 also has the effect of indicating at 139 that it is no longer the local players turn and enables (as indicated by line 139) the serial port listener at 132 to detect an event from the remote player, again via the internet.
If the single music and or singer player practice mode is selected, the internet communications sequences are disabled, other software sequential operating routines continue as above described and the players drum system stroke, hand-smart microphone contact, and audio feedback information are communicated only to the computer located at the players site and the performance information analyzed and displayer only at the local players site.
When a game is won, lost, or terminated, the drum software system generates the appropriate output signals 156 (FIG. 10, displays the player performance information, and resets to initial pre-game conditions. If one player opponent quits the game or is “timed out” (due to excessive delay in play) and the remaining player wishes to continue play, the software resumes an internet search for another opponent 152 and 153.
Using programming as contained in the accompanying microfiche appendix, one skilled in the art can readily accomplish the game programming described. Alternative programming too will be apparent from the foregoing functional description and the illustrations contained in the appended drawings.
While a preferred embodiment has been described, it will be appreciated that many variations and modifications in the system, its operation, and its various components may be made without departure from the spirit and scope of invention as set forth in the appended claims.
