`CELLULAR PHONE WITH EXPANSION
`MEMORY FOR AUDIO AND VIDEO
`STORAGE
`
`FIELD OF THE INVENTION
`
`The present invention relates generally to mobile com-
`munication devices, and more particularly to portable radio
`communication devices having an integral entertainment
`module including RAM or ROM for storing audio, video
`and/or 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 par-
`ticular, portable electronic devices such as audio CD players,
`FM/AM radio receivers, and even television or video tape/
`disc players have become increasingly popular among con-
`sumers 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 tape/disc) typically suffer
`from motion induced distortion otherwise known as bounc-
`
`ing 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 manner
`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 45
`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 entertainment/security services to the athletically
`active consumer, the need to carry multiple pieces of equip- 50
`ment is generally viewed as inhibiting or impairing to their
`athletic endeavors.
`
`there is and continues to be a need for a
`Therefore,
`practical and efficient technique for incorporating the func-
`tionality of audio and/or video playing devices within wire- 55
`less communications devices such as cellular telephones.
`
`SUMMARY OF THE INVENTION
`
`The present invention is a cellular telephone particularly 60
`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 trans-
`ceiver unit includes a fully functional transceiver capable of 65
`sending and receiving voice and data signals via an RF
`carrier. The transceiver unit has an integral digital entertain-
`
`2
`
`ment 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 does 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 and/or an expansion RAM. In those embodiments
`having an 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 microproces-
`sor, 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 con-
`nected to the phone by a wired or wireless link. Because of
`its integration into the cellular phone, the digital entertain-
`ment 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 commu-
`nications 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. Locat-
`ing 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.

`The cellular phone 10 of the present invention is particularly
`adapted for use during leisure activities such as jogging,
`hiking, gardening, etc.
`The cellular phone 10 includes a transceiver unit 12 and
`a headset 40 which can be worn on the head by the user. The
`transceiver unit 12 includes a main 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 and/or 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 accord-
`ing 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 trans-
`ceiver unit 12 of the present invention does not include an
`internal microphone and speaker, though such is within the
`scope of the contemplated invention.
`The headset 40 includes stereo speakers 42 and micro-
`phone 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 trans-
`ceiver 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 micro-
`processor 20. The jack could also connect 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
`carrier or magnetic link.
`invention
`The portable telephone 10 of the present
`includes a built-in digital entertainment module 50 (DEM)
`which allows music or other audio signals to be “played-
`back through the cellular telephone’s headset 40. The enter-
`tainment module 50 includes extended RAM and/or remov-
`able 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 FIG. 3, a schematic diagram of the
`digital entertainment module 50 is shown. The digital enter-
`tainment 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. Digi-
`tized 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 “intemet-
`enabled” phone 10. The removable ROM 56 is preferably in
`the form of a cartridge which fits 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
`to the belt or other article of clothing worn by the user. The
`headset 40 is placed on the user’s 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 activi-
`ties. 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 termi-
`nated. 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 com-
`munication 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 entertain-
`ment module 10 to share components with the cellular phone
`10 to take advantage of the phone’s communication capa-
`bility 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 FIGS. 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 compo-
`nents. As shown in FIGS. 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 embodi-
`ment 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.
`FIGS. 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 num-
`bers will be used to identify similar components. As shown
`in FIGS. 6 and 7, the third embodiment includes a trans-
`ceiver unit 12, headset 40, and adapter 70. The transceiver
`unit 12 includes a transceiver 18, microprocessor 20, pro-
`gram memory 22, audio processing circuits 24, keypad 30,
`and display 32. In addition, the transceiver unit 12 in the

`includes an internal microphone and
`third embodiment
`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 70 is plugged into the transceiver unit 12.
`An input/output 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 control of the micro-
`processor 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 FIGS. 6 and
`7 is advantageous in that it allows the transceiver unit 12 to
`be sold without the digital entertainment module 50 and later
`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 entertain-
`ment module 50 could include a broadcast receiver for
`receiving conventional radio and TV broadcasts in addition
`to its entertainment memory.
`The present invention may, of course, be carried out in
`other specific ways than those herein set forth without
`departing from the spirit and essential characteristics of the
`invention. The present embodiments are, therefore, to be
`considered in all respects as illustrative and not restrictive,
`and all changes coming within the meaning and equivalency
`range of the appended claims are intended to be embraced
