This information is modulated by the telephone control means3, and transmitted from the antenna2by radio to the base station (or the parent unit), and when it is connected to the called party, the apparatus enters a busy mode. A voice of the user in busy mode is input from the microphone4, modulated by the telephone control means3and transmitted to the base station by radio. Conversely, a voice of the other party is inputted to the antenna2by radio from the base station, demodulated by the telephone control means3and outputted from the speaker5. Upon termination of the busy mode, the apparatus is turned on-hook state by the operating means6thereby to disconnect the channel.

Also, in the case where the battery7is so consumed that it requires charging in busy mode, the charger9sets the portable telephone apparatus1, and charges the battery7through the power supply means8from the power supply unit10. The power supply means8may be an electrode-contacting type, but the contactless type using an induction coil is in current mainstay.

DESCRIPTION OF THE EMBODIMENTS

A portable telephone apparatus according to an embodiment of the invention will be described with reference to the drawings.FIG. 1is a block diagram showing a portable telephone apparatus and peripheral devices according to a first embodiment of the invention. InFIG. 1, numerals1to10designate components parts having the same function as the corresponding parts of the conventional apparatus, which with the same reference numerals attached thereto, will not be described. Numeral11designates a memory such as a flush ROM constituting storage means for storing the compressed music data, numeral12data restoration means for reading and expanding the music data stored in the storage means, converting them into an analog signal, and reproducing them as a music signal, numeral13switching means for switching between the voice signal demodulated by the telephone control means3and the music signal reproduced by the data restoration means12in response to a switching signal from music control means14and outputting the selected signal to the speaker5, numeral14the music control means for controlling the storage means11and the data restoration means12by the control signal from the operating means6or the telephone control means14, numeral15communication means for downloading the compressed music data from an external source, numeral16an audio apparatus having the function of reproducing the music source and compressing it as data, numeral17a player unit for reproducing various media such as CD, MD or cassette tape, processing the signal in a way corresponding to each type of medium, and outputting the signal in a predetermined digital format, and numeral18data compression means for compressing the output of the player into a format that can be restored by the data restoration means12.

An operation of the portable telephone apparatus having the aforementioned configuration will be described.

The operation of the telephone set using the portable telephone apparatus1is substantially the same as the operation in the prior art. The exception is that the switching means13is inserted before the speaker5for selecting the voice signal or the music signal according to whether the telephone set is in off-hook or not and outputs the resulting signal to the speaker5. Specifically, in response to the control signal from the operating means6and the telephone control means3, the music control means14determines whether the telephone set is in off-hook or not and notifies the result of determination to the switching means13. In the case where the telephone set is in off-hook, the switching means13selects the voice signal, and otherwise, selects the music signal from the data restoration means12. Now, the music reproducing operation by the portable telephone apparatus1according to this embodiment will be described.

First, the compressed music data input through the downloading communication means15are accumulated in the storage means11. The user selects a desired musical number through the operating means6, and the result is notified to the music control means14. The music control means14causes outputs the storage means11to output the data of the corresponding portion, and expanding and converting it into an analog signal in the data restoration means12, reproduces it as a music signal. In the process, the switching means13selects the music signal and the music begins to pour out from the speaker5. In the case where the earphone of headphone type which begins to be widely used is employed, the user can enjoy the music more. Even in the case where the speaker5is monaural, the communication means15, the storage means11and the data restoration means12are desirably configured as stereophonic means in case of hearing the music through the earphone of headphone type.

In the case where the need arises of sending a call or a call arrives during the reproduction of the music, the user turns the phone into off-hook by the operating means6. As a result, the switching means13selects the voice signal as described above, and thus the speech can be started. Upon complete speech and when the telephone set turns on-hook, the switching means13selects the music signal again so that the music can be reproduced from the speaker5.

During this interruption due to the busy mode, the following choices are available for reproducing the music.

(1) While the telephone set is in off-hook, the storage means11and the data restoration means12are reset to an initial state, and when the telephone set turns on-hook, a number is selected anew.

(2) As soon as the telephone set turns off-hook, the operation of the storage means11and the data restoration means12are suspended, while when the telephone set turns on-hook, the operation is continued.

(3) Also during the off-hook state, the operation of the storage means11and the data restoration means12is continued, but the switching means13is switched.

Each of the choices has an advantage and disadvantage, and any one of them may be used. Desirably, the apparatus is so configured that the user can set his choice.

The storage means11is configured to read/write the telephone data such as the abbreviated dial and the data such as memo data produced by the operating means6as well as the music data.

The operation of compressing and downloading the music data according to this embodiment will be described.

The audio apparatus16is assumed to include a player unit17corresponding to at least one of a plurality of media including the CD, MD, cassette tape and the DAT. The player unit17converts the output of any type of the medium into a predetermined digital format such as WAVE which can be compressed by the data compression means18. For this purpose, the digitizing operation such as sampling is performed for the analog medium including the cassette tape. For other digital media, too, the output thereof is converted into the predetermined digital format described above by manipulating the format of the music data recorded.

In the data compression means18, the input music data is compressed and the data amount reduced in order to reduce the time required for downloading or the capacity of the storage means11.

Any method of compressing the music data can be employed as far as it matches the data restoration means12.

MP3 (MPEG1 Audio Layer 3), for example, is desirable as the data amount can be compressed to about one tenth with the sound quality maintained at a level equivalent to CD. Other appropriate compression methods can also be selected in relation to the capacity of the storage means11. With the increase in the capacity and reduction in a price of the storage means11, a method may become available in which the data is downloaded directly to the storage means11without any compression or expansion in the data restoration means12.

The music data compressed in the manner described above is downloaded to the storage means11in the portable telephone apparatus1by the communication means15. The communication means15may be of any type including wired, radio or optical, as far as it has an interface matching the portable telephone apparatus1such as RS232 or IrDA.

The charging operation according to this embodiment is similar to that in the prior art.

FIG. 2is a block diagram showing a portable telephone apparatus and peripheral devices according to a second embodiment of the invention. InFIG. 2, the points different from the first embodiment will be described.

InFIG. 2, the audio apparatus16is integrated with the charger9shown inFIG. 1. Specifically, with the portable telephone apparatus1set in the charger9, the downloading communication means15is connected. This configuration is more functional than that ofFIG. 1as the peripheral devices required for the charging and the downloading of the music data can be grouped into a single set. Also, when arrangement is made to start the charge operation as soon as the downloading is started, the charging time can be reduced while at the same time compensating for the power consumption of the portable telephone apparatus due to the downloading operation.

FIG. 3is a block diagram showing a portable telephone apparatus and peripheral devices according to a third embodiment of the invention. The different points inFIG. 3from the first embodiment will be described.

InFIG. 3, the method of downloading the music data is different from that ofFIG. 1. Specifically, assume that the music data arrives by radio from the base station and is inputted from the antenna. The signal inputted to the antenna2is demodulated by the telephone control means3, and extracted as digital data and accumulated in the storage means11through the music control means14. The user registers a request for a number beforehand in the base station through the operating means6. The radio wave arriving from the base station carries both the voice signal and the music signal.

FIG. 4is a block diagram showing a portable telephone apparatus and peripheral devices according to a fourth embodiment of the invention. The difference of the configuration shown inFIG. 4from the first embodiment will be described below.

InFIG. 4, the switching means13ofFIG. 1is replaced by mixing means19arranged at two points. The mixing means19amixes the voice picked up by the microphone4with the music signal, and outputs it to the telephone control means. The mixing means19b, on the other hand, mixes the voice of the other party outputted from the telephone control means3with the music signal and outputs it to the speaker. The mixing ratio is variable according to the control signal from the music control means14, whereby the two mixing means perform the same function as the switching means of the first embodiment.

The operation of the mixing means19apermits a voice of the user to be carried with the music to the other party. Also, the operation of the mixing means19bmakes it possible to mix the voice of the other party outputted from the telephone control means3with the music and to output it to the speaker. Thus, the conversation with a background music can be enjoyed.

Also, when the speech, i.e. the busy mode is suspended, the music can be furnished to the other party as a waiting message by controlling the mixing means19a.

FIG. 5is a block diagram showing a portable telephone apparatus and peripheral devices according to a fifth embodiment of the invention. The points different inFIG. 5from the first embodiment will be described.

InFIG. 5, the communication means15is capable of bidirectional communication, and the information inputted by the operating means6can be transmitted to the audio apparatus16unlike inFIG. 1. As a result, the retransmission is facilitated in case of communication error which may occur during the downloading operation. Also, the selection of a number to be downloaded and a setting of timing of starting the downloading are also made possible by the operating means6of the portable telephone apparatus1.

FIG. 6is a block diagram showing a portable telephone apparatus and peripheral devices according to a sixth embodiment of the invention. The points inFIG. 6different from the first embodiment will be described below.

InFIG. 6, the storage means11is assumed to be a device in the form of removable card such as a smart card. The built-in data can be inputted/outputted through the card interface20. In this case, the music data read from the storage means11by the card interface20ais outputted to the data restoration means12.

In this case, the music data is written in the storage means11by purchasing a prewritten medium and exchanging it to permit the user to enjoy various numbers, or as shown inFIG. 6, the audio apparatus16is equipped with the card interface20bfor the user to write by himself.

FIG. 7is a block diagram showing a portable telephone apparatus and peripheral devices according to a seventh embodiment. The different points ofFIG. 7from the first embodiment will be described below.

InFIG. 7, numeral21designates a headphone jack, through which the music signal reproduced by the data restoration means12can be heard through the headphone. The voice signal outputted from the telephone control means3, on the other hand, is directly outputted from the speaker5. This double system of the voice output means can realize a similar function to the first embodiment with a simple circuit configuration. At the same time, the sound quality can be improved by separating the circuits. Also, in the case where the telephone set is in off-hook, judging from the key operation of the operating means6or the busy mode of the telephone set, the music control means14may suspend the operation of the data restoration means12and mutes the music signal.

The aforementioned configuration provides a portable telephone apparatus capable of music reproduction.

With the portable telephone apparatus according to this invention, unlike the conventional portable telephone apparatus, the user wanting to use both the phone and music functions is not required to carry both the portable telephone apparatus and the portable audio apparatus at the same time, but a single portable telephone apparatus can realize both the phone function and the music reproduction function also very conveniently.

Also, in view of the fact that the audio player having the function of compressing the music data for various media and downloading it to the portable telephone apparatus is integrated with the charger, the peripheral devices required for charging the battery and downloading the music data can be integrated into a single device for an improved functionality. As a result, the time for charging is saved thereby to compensate for the power consumption of the portable telephone apparatus due to the downloading operation.

Also, the configuration is such that the music data can be downloaded over the radio wave from the base station, and therefore the audio apparatus for compression and downloading is eliminated.

Further, since the voice signal is mixed with the music signal and outputted from the speaker or transmitted to the other party of speech, the conversation with a background music can be enjoyed or the music can be furnished to the other party as a waiting message while the busy state is suspended.

Furthermore, the communication means for compression and downloading between the audio apparatus and the portable telephone apparatus is capable of bidirectional communication, and therefore the retransmission is facilitated in case of a communication error which may occur during the download operation. Also, the selection of a number to be downloaded or the timing of starting downloading can be set by the operation of the portable telephone apparatus.

In addition, since the storage means is removable, the block for downloading is eliminated, and the user can enjoy various numbers simply by replacing the storage means.

Further, the voice signal is outputted from the speaker and the music signal is outputted from the headphone jack, and therefore a similar function can be realized with a simple circuit configuration. Also, the sound quality is improved by separating the circuits.
