Single channel music lantern control circuit principle

As shown in the figure, the circuit lantern control circuit can use the music beat output signal to control the flashing of the lantern with the music beat. Circuit principle: The core component of this flashing light control circuit is the music integrated block HFC160. In addition to the music output function, this chip also has a music beat output function. Figure a is a pin function diagram of this chip.
The AC power source is bridge-rectified to generate a DC power supply for the music circuit and the lantern circuit. The beat signal PS output controls the on and off of the unidirectional thyristor SCR through a delay link composed of C2 and R5. Adjusting C3 and R5 adjusts the duration of the light. R6 is the release resistor, and the music signal output OUT is amplified by the triode T to push the buzzer BZ to emit music. Single channel music light control circuit
