Who invented the voice control light?

Voice-activated lamp is a kind of voice-activated electronic lighting device, which consists of audio amplifier, frequency selection circuit, delay start circuit and SCR circuit. It provides a sound control lamp with simple operation, flexibility, strong anti-interference ability and sensitive control. It sends out a control signal "hiss" of about 1 s through the human mouth, which can conveniently turn on and off the voice-activated lighting device in time, and has the function of automatic time-delay closing to prevent false triggering, and is equipped with a manual switch, which makes its application more convenient. The voice control lamp consists of a microphone, an audio amplifier, a frequency selection circuit, a voltage doubler rectifier circuit, an amplitude discrimination circuit, a constant voltage source circuit, a delay start circuit, a controllable delay switch circuit and a silicon controlled rectifier circuit.
