A voice-activated lights control circuit

22W by Ct and R, RC Buck, rectified by n. c, filtering. vz 3V DC regulated output power, before U, V2 and MIC power supply. When the audio signal to the beam, the microphone MI

C acoustic energy into electrical energy, and then the general discharge tube T and after coupling, can be entrusted to two-way silicon v dispatch a trigger voltage control, use audio to control thyristor conduction and cut u :, D generated so lights sparkle.
