In the Figure, B is the electret condenser microphone which can pick up the the sonic signal and output corresponding electrical signals, then it is amplified by VT1 and sent to Manifold HL3034 ⑤ feet by RP1, and it can control internal voltage controlled oscillator VCO after being amplified, the oscillation frequency changes with audio signal strength. Therefore, changing Q1 ~ Q4 output pulse conversion rate can make the four groups lantern E1 ~ E4 cycle rate change with the strength of the sound waves. Adjusting the RP1 can change the voice sensitivity Lantern circulation rate of the circuit.
