Abstract
A microphone senses a sound generated by the user clapping his hands and converts the sound into an electric signal which is applied to a flip-flop circuit to set the latter. The output of the flip-flop circuit is supplied through a time constant circuit to a drive and control circuit for operating a sound generating device having a reproducing stylus and a recorded disk. A reset signal producing circuit is provided to produce a reset signal for the flip-flop circuit when a second sound is sensed by the microphone within a predetermined time period set by the time constant circuit, thereby stopping the operation of the sound generating device.
