`
`CELLULAR PHONE WITH EXPANSION MEMORY
`FOR AUDIO AND VIDEO STORAGE
`
`FIELD OF THE INVENTION
`
`The present invention relates generally to mobile communication devices, and
`
`more particularly to portable radio communication devices having an integral
`
`entertainment module including RAM or ROM for storing audio, video andfor still
`
`images.
`
`BACKGROUND OF THE INVENTION
`
`In the past two decades. advances in digital electronic technology have led to
`
`a rapid growth in the area of entertainment oriented consumer electronic devices.
`
`in
`
`particular. portable electronic devices such as audio CD players, FIWAM radio
`
`receivers, and even television or video tapeldisc players have become increasingly
`
`popular among consumers as they have become small, lightweight, and easy for an
`
`individual to carry.
`
`While quite popular with consumers, the mass storage type devices (audio
`
`CD, video tapeldisc) typicaily suffer from motion induced distortion othenrvise known
`
`as bouncing or skipping. These problems arise, in part, as a result of the required
`
`motion of the mass storage medium during normal operation. That is, in the case of
`
`an audio CD or a video disc, the disc which comprises the storage medium is
`
`typically spun or rotated at a relatively high speed while the information stored on the
`
`disc is read by an associated read head. Proper and precise alignment of the read
`
`head with respect to the spinning storage medium must be maintained at all times in
`
`order to insure error free reading of the stored data. Such precise alignment is often
`
`difficult to maintain when the audio or video player is being used in mariner which is
`
`conducive to extreme vibration or mechanical shock.
`
`in practice. mechanically harsh

`
`activities such as jogging or running are common among users of portable
`
`electronics, particularly with regard to the use of portable audio CD players.
`
`In such
`
`cases, skipping or bouncing artifacts induced in the CD player can seriously impair
`
`the overall performance of the player.
`
`With further regard to the recreational athletic activities of portable electronics
`
`consumers. it is often the case such consumers will carry not only an audio CD
`
`player for entertainment purposes. but also a cellular telephone for safety and
`
`security. Although such equipment provides the desired entertainmentisecurity
`
`services to the athletically active consumer, the need to carry multiple pieces of
`
`equipment is generally viewed as inhibiting or impairing to their athletic endeavors.
`
`Therefore, there is and continues to be a need for a practical and efficient
`
`technique for incorporating the functionality of audio andior video playing devices
`
`within wireless communications devices such as cellular telephones.
`
`SUMMARY OF THE INVENTION
`
`The present invention is a cellular telephone particularly adapted for leisure
`
`activities. The cellular telephone of the present invention includes a portable
`
`transceiver unit and a headset which can be worn by the user during leisure activities
`
`such as jogging, biking, gardening. etc. The transceiver unit includes a fully
`
`functional transceiver capable of sending and receiving voice and data signals via an
`
`RF carrier. The transceiver unit has an integral digital entertainment module
`
`including a memory for storing music or other audio signals for playback through the
`
`headset. For purposes of this application, memory means all forms of computer
`
`memory but dies not include disk storage. tape storage or other memory requiring
`
`electromechanical read systems. The memory may be in the form of a removable
`
`ROM cartridge andior an expansion RAM.

`
`expansion RAM, an input port is provided for loading music or other audio signals
`
`into the expansion RAM from a CD player, computer, or other source of digitized
`
`audio.
`
`Under the control of the transceiver unit's microprocessor, the digitally stored
`
`audio signal is played out through the telephone's headset, which in the preferred
`
`embodiment comprises stereo headphones. The headset may be connected to the
`
`phone by a wired or wireless link. Because of its integration into the cellular phone.
`
`the digital entertainment module can share components already present in the
`
`cellular phone. Such savings would not be available if a CD player were simply
`
`aggregated with the phone. Further. the use of solid state RAM or ROM, as
`
`opposed to disc storage, eliminates the need for bounce control circuitry. This
`
`enables the disclosed invention to provide cellular communications and
`
`entertainment during leisure activities.
`
`In another aspect of the present invention, the digital entertainment module
`
`could be located in a removable battery pack which attaches to the transceiver unit,
`
`or in a separate adapter which plugs into the transceiver unit. Locating the digital
`
`entertainment module in either a battery pack or separate adapter allows the
`
`manufacturer to offer the digital entertainment module as an optional accessory
`
`which does not need to be purchased at the same time the cellular phone is
`
`purchased. This allows consumers who purchase a phone without the digital
`
`entertainment module to later purchase the battery pack or adapter as an upgrade to
`
`the existing phone.

`
`housing 14 and a removable battery pack 16 containing a rechargeable battery 28.
`
`Housing 14 of the transceiver unit 12 contains an RF transceiver 18, control logic 20.
`
`program memory 22. and audio processing unit 24 which are operatively connected
`
`by a system bus 26. The RF transceiver 18 may be, for example, a class 1 mobile
`
`phone transceiver capable of transmitting and receiving radio signals containing
`
`voice andlor data. Audio processing unit 24 processes voice and data signals that
`
`are transmitted and received by the transceiver 18. Audio processing unit 24 may
`
`include voice recognition circuitry to enable activation and use of the phone 10 by
`
`voice commands for truly hands-free operation. The control logic 20 controls the
`
`operation of the transceiver 18 according to instructions stored in program memory
`
`22. A keypad 30 and display 32 provide a user interface. Keypad 30 enables the
`
`user to enter dialing instructions and commands to initiate a call. and to select
`
`options. The display 32 displays the number dialed and call status information to the
`
`user. Display 32 may also display instructions or options to the user. Unlike a
`
`conventional cellular phone, the transceiver unit 12 of the present invention does not
`
`include an lntemal microphone and speaker, though such is within the scope of the
`
`contemplated invention.
`
`The headset 40 includes stereo speakers 42 and microphone 44 that are
`
`connected to the transceiver unit 12 by a cable 46. Cable 46 may include a plug (not
`
`shown) which removably mates with a corresponding jack on the transceiver unit 12.
`
`The cable 46 connects to the system bus 26 which routes audio signals from the
`
`audio processing unit 24 to and from the headset 40 under the control of the
`
`microprocessor 20. The jack could also oonnect directly to audio processing circuit
`
`24. Alternatively, the headset 40 could communicate wirelessly with the transceiver

`
`unit 12, for example, by means of an infrared carrier, low power RF can'ier or
`
`magnetic link.
`
`The portable telephone 10 of the present invention includes a built-in digital
`
`entertainment module 50 (DEM) which allows music or other audio signals to be
`
`“played-back through the cellular teiephone's headset 40. The entertainment
`
`module 50 includes extended RAM andior removable memory cartridges for storing
`
`music or other audio signals which can be played back through the headset 40 of the
`
`phone 10.
`
`Referring now to Figure 3, a schematic diagram of the digital entertainment
`
`module 50 is shown. The digital entertainment module 50 includes a secondary bus
`
`52, extended random access memory (RAM) 54, removable ROM 56, and an input
`
`58. The extended RAM 54 may, for example, be a flash EPROM chip capable of
`
`storing digitized audio. Digitized audio is loaded into the flash EPROM via input 58.
`
`The input 58 may be a serial port, parallel port, infra~red data port, modem, or any
`
`other type of input device capable of interfacing with a source of digitized audio, such
`
`as a CD player, or computer.
`
`It is also contemplated that audio may be obtained
`
`from the transceiver unit 12 in an "internet-enabled" phone 10. The removable ROM
`
`56 is preferably in the form of a cartridge whichfits into a slot in the transceiver unit
`
`12. The ROM cartridge 54 would contain pre-recorded music which could be
`
`purchased by the user.
`
`in the preferred embodiment, the data format of both the
`
`extended RAM 54 and removable ROM 56 would be organized according to CD-
`
`ROM standards, which is 14 bits per sample and 44.1 k samples per second.
`
`in operation, the user would insert a removable ROM cartridge 56 into the
`
`transceiver unit 12 or load audio into the extended RAM 54 from a CD player,
`
`computer, or other source of digitized audio. The transceiver unit 12 is attached the

`
`belt or other article of clothing wom by the user. The headset 40 is placed on the
`
`users head and connected to the transceiver unit 12. Playback of audio in the
`
`extended RAM 54 or removable ROM 56 could be activated via the keypad 30, or
`
`alternately, by voice command. The audio would be played back through the
`
`headset 40 under control of the microprocessor 20 while the user engages in leisure
`
`activities. When an incoming call is received, the microprocessor 20 automatically
`
`mutes or stops the playback of audio from the digital entertainment module 50 until
`
`the call is terminated. Preferably, the transceiver unit 12 includes a preferred caller
`
`list stored in a screening memory which may be part of program memory 22 or
`
`separate therefrom but in communication with the control logic 20. This preferred
`
`caller list is used to screen incoming calls such that only calls from callers on the
`
`preferred caller list cause the playback of audio from the digital entertainment
`
`module 50 to be muted or stopped; calls from callers not on the preferred caller list
`
`preferably do not cause such response. Upon termination of the call, the
`
`microprocessor 20 would unmute or restart the playback of audio from the digital
`
`entertainment module 50.
`
`A significant advantage of the present invention is that audio is played back
`
`from solid state RAM or ROM memory thus eliminating the need for bounce control
`
`circuitry which is commonly used in portable CD players. Further, because of its
`
`integration into the cellular phone 10, there is no need for the user to carry both a
`
`portable audio player and a cellular phone. Moreover, integration of the
`
`entertainment module 50 into the cellular phone 10 allows the entertainment module
`
`10 to share components with the cellular phone 10 to take advantage of the phone's
`
`communication capability to load the RAM 54. Thus, the present invention could

`
`replace both a conventional cellular phone and portable audio player at lower cost
`
`than a conventional walk-man and telephone.
`
`Referring now to Figures 4 and 5. a second embodiment of the present
`
`invention is shown. The second embodiment is similar to the first embodiment and.
`
`therefore. the same reference numerals will be used to identify similar components.
`
`As shown in Figures 4 and 5. the second embodiment of the phone 10 includes a
`
`transceiver unit 12 with a removable battery pack 14, and a headset 40 connected to
`
`the transceiver unit 12. The transceiver unit 12 includes a transceiver 18,
`
`microprocessor 20, program memory 22, audio processing circuits 24. keypad 30
`
`and display 32 as previously described. Similarly, the headset 40 includes stereo
`
`speakers 42 and microphone 44. The second embodiment differs from the first in
`
`that the digital entertainment module 50 is contained within the removable battery
`
`pack 14. The entertainment module 50 connects to a secondary bus in the battery
`
`pack 14. When the battery pack 14 is attached to the transceiver unit 12, a
`
`connection is made between the secondary bus in the battery pack 14 and the main
`
`bus 26 of the transceiver unit 12. The main bus 26 and secondary bus enable the
`
`routing of audio signals between the entertainment module 50 and audio processing
`
`circuits 24 under the control of the microprocessor 20.
`
`Figures 6 and 7 show a third embodiment of the present invention. The third
`
`embodiment is similar to the first and second embodiments and therefore the same
`
`reference numbers will be used to identify similar components. As shown in Figures
`
`6 and 7, the third embodiment includes a transceiver unit 12, headset 40. and
`
`adapter 70. The transceiver unit 12 includes a transceiver 18, microprocessor 20.
`
`program memory 22, audio processing circuits 24, keypad 30, and display 32.
`
`In
`
`addition, the transceiver unit 12 in the third embodiment includes an internal

`
`microphone and speaker 34 and 36 respectively. Thus. the transceiver unit 12 can
`
`be used without the headset 40.
`
`The headset 40 includes a pair of stereo speakers 42 and microphone 44.
`
`The headset 40 is connected by a cable 46 to the adapter 70. The entertainment
`
`module 50 is contained in the adapter 70. The adapter 70 includes a secondary bus
`
`72 which connects to the main bus 26 on the transceiver unit when the adapter ‘I0 is
`
`plugged into the transceiver unit 12. An inputloutput circuit 74 routes audio signals
`
`to and from the headset 40.
`
`When the transceiver unit 12 is used without the adapter 70, audio signals are
`
`routed under the contro! of the microprocessor from the audio processing circuits 24
`
`to the internal microphone and speaker 34 and 36. When the adapter 70 is plugged
`
`into the transceiver unit 12, the audio signals are routed to the microphone 44 and
`
`speakers 42 on the headset 40.
`
`The configuration of the phone 10 shown in Figures 6 and 7 is advantageous
`
`in that it allows the transceiver unit 12 to be sold without the digital entertainment
`
`module 50 and Eater upgraded by the consumer. The adapter 70 and headset 40
`
`could be sold separately as an accessory or at a later time as an upgrade. Thus. a
`
`single phone could be manufactured for use both with and without the digital
`
`entertainment module 50.
`
`it will be apparent to those skilled in the art that the digital entertainment
`
`module 50 could also be used to store video or still images which could be output to
`
`the display 32 of the transceiver unit 12. Any sound accompanying the video would
`
`be played back through the headset 40 or internal speaker.
`
`It should also be
`
`apparent that the digital entertainment module 50 could include a broadcast receiver
