POWER SWITCHING APPARATUS USING BIOLOGICAL ENERGY FOR TAPE CASSETTE PLAYER

摘要

The present invention provides a cassette capable of controlling the power supply to the internal circuit using the bioenergy, off. The cassette of the present invention includes a conductive touch plate installed at the body contact portion of the earphone, an amplification unit 4 for amplifying the bioenergy flowing through the touch plate 1, and an output of the amplification unit 4. Responsively controlling the power supply of the cassette. According to the present invention, since the operation of the cassette is stopped while the earphone is separated from the body, the life of the battery and the cassette can be greatly extended.
