The micro audio component system of the present invention includes a compact disc playback unit 10, an audio tape deck unit 12, and a tuner unit 14 integrally with the main body 100, and includes left and right speakers (L-SP, R-SP). It is connected with the computer 200 and the communication cable 300 through. The computer 200 includes a keyboard 210, a mouse 220, a main body 230, and a monitor 240. The audio output terminal of the computer is connected to the auxiliary audio input terminal of the main body 100.

2 shows a circuit configuration of a computer controllable micro audio component system according to the present invention. In FIG. 2, the system includes a tuner unit 14 capable of receiving radio broadcasts, an audio tape recording and reproducing unit 14, an optical disc reproducing unit 10 for reproducing an audio signal from a compact disc, and the respective units. A signal selector 16 for selecting one of the output audio signals, a mixing unit 18 for mixing the selected audio signal and a microphone input signal, and an amplification for amplifying the mixed audio signal and outputting the amplified audio signal to the audio output terminal 22. The unit 20, a speaker 24 connected to the output terminal 22, a power supply unit 26 for supplying a power voltage to the respective sections in response to a control signal, and a display unit 28 for displaying an operation mode, time, and the like. ), An operation unit 30 for processing a key signal for inputting a command, a remote control input unit 32 for inputting a remote control command, a computer interface unit 34 for inputting a command supplied from a computer, and Control panel 30, remote control input unit 32 And a control unit 36 which checks the command input from the computer interface unit 34 and controls each unit according to the input command, and is integrally formed in the main body 100.

The computer interface 34 is connected to the computer 200 through a communication cable 300 connected to the connector 40. The computer interface 34 preferably uses a serial communication port such as RS-442 or 232C.

The auxiliary input terminal AUX1 is connected to the signal selector 16, and the audio output terminal of the computer is connected to the auxiliary input terminal.
