defect mark, and it is emitted as a radio wave, so it is% k in another ll0vll book. The present
invention is economical and intended to provide a letter of affirmation Kt et al.-Wireless
earphone with Sat> device, and an embodiment of the present invention will be described
together with the cylindrical surface. As shown on 1st @, switch 2 to the audio output cabler 1 of
audio equipment such as a television receiver. It is set to switch whether the speaker 3 is
connected or the series-path or the light source # 4 of the light-emitting body 4 such as a light
bulb and the like # 1 is switched. The light bulb 4 is exposed and attached to the front of the
cabinet of the audio device. The light modulated by the audio output should go out of the audio
equipment. The light emitting unit 6 of FIG. 2 is provided with the fill / 7 in the circuit 11 of FIG.
1 and 100 # i 100, and the receiving unit is provided with the photoelectric conversion @ 110
via the fill 71a and the lens. The output of the O photoelectric II III unit 100 is amplified by the
amplifier 511, and the speaker 12). As shown in the figure, the light adjusted in quality by the
sound output of the audio equipment is photoelectrically converted on the receiving side, and the
output is increased and broadened, and the speaker 2 is released. As described above, according
to the present invention, it is not necessary to use a KFM modulator and a light modulator as in
the prior art, as long as a light emitter such as a light bulb and a photoelectric converter II may
be provided. Since light is used as a medium, no letter is given to other devices.
