The circuit is as shown. It consists of audio pich-up and amplifier circuit, light control circuit and AC depressurization rectifier circuit. BM is CRZ2 electret condenser microphone, it can change picked up sound singal into electrical signal, it is amplified by VT1 amplifier then added to emitter follower VT2, and added to input UIN terminal 5-foot of LC181 rectifier amplifier, to voltage control and modulate the internal VCO.
