【0004】

An object of the present invention is to listen to music output from an external audio device while charging by setting a mobile radiotelephone terminal capable of storing music or the like in a charger connected to the external audio device at home or the like. The purpose is to provide an audio device using a portable radiotelephone terminal capable of providing an audio device.

【0005】

[Means for solving problems]

In order to achieve the above-described object, the invention according to claim 1 of the present invention is a receiving means for receiving distribution information distributed from a center database and receiving the distribution information distributed from the center database in a mobile radiotelephone terminal for transmitting and receiving voice information. A mobile radiotelephone terminal having a memory means for downloading and storing the distributed information, a selection means for selecting information from the memory means, and an output means for reading and outputting the selected information from the memory means, and the mobile phone. A charger for charging a radiotelephone terminal, which has a connecting means for connecting to the output means of the mobile phone terminal and a transmitting means for transmitting an output signal from the output means to an external acoustic device. It is characterized in that it is composed of the external acoustic device that reproduces the output signal and outputs it acoustically.

【0006】

Further, in the invention according to claim 2, in the acoustic device using the portable telephone terminal according to claim 1, it is possible to instruct the control procedure of the external acoustic device by operating the operation keys of the portable telephone terminal. It is characterized by that.

【0007】

According to the above configuration, it is possible to play and listen to music data stored and stored in a mobile wireless telephone terminal with an existing external audio device while charging the music data and the like.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram for explaining a communication system in which the mobile phone terminal of the present invention is used. In the figure, the mobile radiotelephone 1 is configured to be wirelessly connectable via a center 3 having a music source and a related text information base and a public base station 2, and the antenna 1a of the mobile phone 1 and the public base station 2 Data communication is performed wirelessly between the antennas 2a. By operating the operation key 1b of the mobile radiotelephone 1, a desired song is transmitted to the mobile phone 1 from the music source in the center 3, and the desired song is received and stored in the built-in memory. The related character data is displayed on the LCD1c of the mobile radiotelephone 1.

FIG. 2 is an external view showing the configuration of an audio device using the mobile radiotelephone terminal of the present invention. In a home or the like, the mobile wireless telephone terminal 1 capable of storing music or the like is set in a charger 5 connected to an external audio device (audio device) 10 so that the output of the terminal 1 is transmitted. While charging the telephone terminal 1, the music stored in the terminal 1 can be output from an external audio device and listened to without using headphones or the like. Here, the charger 5 includes an external power cord 6 and a cable 7 that transmits the output from the mobile wireless telephone terminal 1 to the external audio device 10.

【0010】

FIG. 3 is a block diagram showing a configuration of an audio device using the mobile phone terminal of the present invention. First, the configuration of the mobile phone terminal will be described. In the figure, 11 is a speaker (headphone), 12 is an amplifier, 13 is a D / A converter, 14 is a CODEC (audio compression / expansion logic), 15 is a flash memory (ROM), 16 is a buffer RAM, and 17 is a demodulator. 18 is the RF section, 19 is the antenna, 20 is the CPU, 21 is the MMI control, 22 is the operation key, 23 is the liquid crystal display (LCD), 24 is the charger interface, 25 is the power supply, and 26 is the charging terminal.

【0011】

The charger includes a terminal interface 53 for connecting to the charger interface 24 of the mobile phone terminal and an interface 54 for an external audio device.

【0012】

The music source received by the antenna 19 is received by the RF unit 18, demodrated by the demodulator 17, and then temporarily stored in the buffer RAM 16. Here, in the case of a normal wireless call, voice information is output as voice to the speaker 11 or headphones via CODEC14. The temporarily saved data is saved in the flash memory (ROM) 15 for saving the music source data. The flash memory 15 has a capacity for recording music sources for several songs. When the user wants to listen to the music, the operation key 22 is operated to select the desired music data from the flash memory 15, and the speaker 11 or the speaker 11 or the music is played as music played via the D / A converter 13 and the amplifier 12. It is output from headphones.

【0013】

Next, when the mobile wireless telephone terminal 1 is set in the charger 5, the music data stored in the internal flash memory 15 is transferred from the mobile wireless telephone terminal 1 to the charger 5 via the charger interface 24 and the terminal interface 53. Is output, and is further input to the external acoustic device 10 via the external acoustic device interface 54.

【0014】

At that time, control such as playback, fast forward, and pause of music data is operated by the operation key 22 of the mobile wireless telephone terminal 1.

【0015】

[Effect of the invention]

As described above, according to the audio device using the mobile phone terminal of the present invention, the voice data interface is connected between the telephone terminal, the charger, and the external audio device simply by setting the mobile phone terminal in the charger. Therefore, the voice and music data stored in the mobile phone terminal can be played back by an external audio device such as a stereo, a component, or a radio cassette player, and can be freely enjoyed. At the same time, the mobile phone terminal can be charged, eliminating the need for an extra connector.
