FIG. 1 is a block diagram of a device for simultaneously processing a plurality of sound sources of an audio device according to the present invention, which is selected when a user wants to simultaneously listen to a plurality of sound sources processed through the first and second sound source processors 110 and 120. The user selector 200 and the sound source processed through the first sound processor 110 intermittently intercept any channel among the left channel L and the right channel R outputted to the signal reproducer 500. A second channel intermittent for intermittently intercepting another channel between the L channel and the R channel outputted through the first channel intermitter 310 and the second sound source processor 120 to the signal reproducer 500 The control unit 400 controls the channel by outputting a control signal to the first and second channel control units 310 and 320 according to a user's selection input through the unit 320 and the user selection unit 200. It is composed.

FIG. 2 is a detailed circuit diagram of a multiple sound source processing simultaneous output device applied to a headphone stereo according to an embodiment of the present invention, and receives a radio wave containing a sound broadcast from a broadcasting station as an antenna and restores a voice signal. ), A tape recorder 102, which is a magnetic recording and playback device using a synthetic resin tape coated with magnetic material, and a user who wants to simultaneously listen to a plurality of sound sources processed through the radio tuner 101 and the tape recorder 102. The simultaneous listening switch 201 for selective input, the microcomputer 401 for selectively outputting the control signal according to the user's input by the operation of the simultaneous listening switch 201, and the control signal of the microcomputer 401. The sound source processed through the radio tuner 101 controls an arbitrary channel among the left channel L and the right channel R output to the earphone 501. According to the first transistor 301 and the control signal of the microcomputer 401, the sound source processed through the tape recorder 102 is interrupted by the first transistor 301 among the L channel and the R channel output to the earphone 501. It consists of the 2nd transistor 302 which interrupts another channel which is not.

In the figure, reference numeral A1 is a preamplifier, A2 is a power amplifier, and VOL is a volume controller.

Referring to Figure 3 attached to the operation and effect of the present invention configured as described above is as follows.

First, when the user operates the simultaneous listening switch 201 to simultaneously listen to a plurality of sound sources processed through the radio tuner 101 and the tape recorder 102, the microcomputer 401 has a DC power supply (Vcc). By the "high" signal is input.

Then, the microcomputer 401 determines that the user wants to listen to a plurality of sound sources at the same time to control the power supply unit (not shown) so that the operating power is supplied to the radio tuner 101 and the tape recorder 102. The channel interrupt control signal is output to the first transistor 301 and the second transistor 302.

As the operating power is supplied, the radio tuner 101 receives a radio wave containing a broadcast signal from a broadcasting station through an antenna, restores a voice signal, and outputs the audio signal to the left channel L and the right channel R, and the tape recorder 102. ), The residual magnet on the recorded tape is taken out as electromotive force by the reproducing head, amplified and output to the L channel and the R channel.

However, at this time, the control signal of the microcomputer 401 is applied to the base terminal, and the first transistor 301 and the second transistor 302 acting as bias voltages are in a conductive state.

Accordingly, the L channel of the left channel L and the right channel R, which is output through the radio tuner 101 to the earphone 501, is blocked, and the sound source processed through the tape recorder 102 is blocked. The R channel of the L channel and the R channel output to the earphone 501 is blocked.

Therefore, the sound source processed through the radio tuner 101 is output only to the R channel of the earphone 501, and the sound source processed through the tape recorder 102 is output only to the L channel of the earphone 501.

Accordingly, the user can listen to the radio broadcast on the left side of the earphone 501 and the tape play sound on the right side of the earphone 501.

As described above, the present invention simultaneously outputs a plurality of sound sources processed through a plurality of sound source processors to a single signal reproducer having a stereo function, but independently processes the plurality of sound sources to the left channel and the right channel of the signal reproducer. By a plurality of sound sources are separated and output in correspondence with each other, it is possible to simultaneously listen to different sound sources with a single audio set.

In particular, when the present invention is applied to a headphone stereo which is easy to carry due to its small size and light weight, and the demand is rapidly increasing, two users can use the left and right earphones separately to listen to different sound sources simultaneously without mutual interference. It can be effective.
