According to a second aspect of the present invention, in the audio device using the portable telephone terminal according to the first aspect, an instruction of a control procedure of the external audio device is issued by operating an operation key of the portable telephone terminal. It is characterized by being possible.

[0007] According to the above configuration, it is possible to play and listen to music data and the like stored and saved in the portable radio telephone terminal with an existing external audio device while charging.

[0008]

Embodiments of the present invention will be described below 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, a portable radio telephone 1 is configured to be wirelessly connectable to a center 3 having music sources and related character information bases via a public base station 2, and an antenna 1 a of the portable radio telephone 1 and a public base station 2 are connected. Wireless data communication is performed between the antennas 2a. By operating the operation key 1b of the portable wireless telephone 1, a desired music is transmitted from the music source in the center 3 to the portable wireless telephone 1, and the received music is received and stored in a built-in memory. The related character data is displayed on the LCD 1c of the portable wireless telephone 1.

FIG. 2 is an external view showing the configuration of an audio device using the portable radio telephone terminal of the present invention. At home or the like, the portable 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 to the portable wireless telephone terminal 1 so that the portable wireless telephone terminal 1 can store the music. Music and the like stored in the terminal 1 can be output from an external audio device while the telephone terminal 1 is being charged, and can be heard without using headphones or the like. here,
The charger 5 includes an external power cord 6 and a cable 7 for transmitting an output from the portable wireless telephone terminal 1 to the external audio device 10.

FIG. 3 is a block diagram showing the 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 D / A
A converter 14 is a CODEC (voice compression / decompression logic),
15 is a flash memory (ROM), 16 is a buffer R
AM and 17 are demodulators, 18 is an RF unit, 19 is an antenna, 20 is a CPU, 21 is MMI control, 2
2 is an operation key, 23 is a liquid crystal display (LCD), 24 is a charger interface, 25 is a power supply, and 26 is a charging terminal.

The charger includes a terminal interface 53 connected to the charger interface 24 of the mobile phone terminal.
And an external audio device interface 54.

The music source received by the antenna 19 is R
The data is received by the F unit 18, demodulated by the demodulator 17, and temporarily stored in the buffer RAM 16. Here, in the case of a normal wireless call, the voice information is CODEC.
The audio is output to the speaker 11 or headphones through the audio signal 14. The temporarily stored data is stored in a flash memory (ROM) 15 for storing 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 user operates the operation keys 22 to select desired music data from the flash memory 15 and to use the D / A converter 1.
3. The music reproduced via the amplifier 12 is output from the speaker 11 or headphones.

Next, the portable wireless telephone terminal 1 is
, The music data stored in the internal flash memory 15 is transferred from the portable wireless telephone terminal 1 to the charger 5 by the charger interface 24 and the terminal interface 53.
, And further input to the external audio device 10 via the external audio device interface 54.

At this time, controls such as reproduction, fast-forward, and pause of music data are operated by the operation keys 22 of the portable radio telephone terminal 1.

[0015]

As described above, according to the audio apparatus using the portable telephone terminal of the present invention, the sound data can be transmitted between the telephone terminal, the charger, and the external acoustic device only by setting the portable telephone terminal in the charger. Interface is connected, so that voice and music data stored in the mobile phone
It can be played on external sound equipment such as a component player and a radio-controlled cassette player, and can be enjoyed freely. In addition, the mobile phone terminal can be charged at the same time, and an extra connector becomes unnecessary.
