The 220V AC mains power is bridge-rectified by VD1~VD4, and outputs a DC voltage of about 3V through the voltage stabilizing circuit composed of R1, R2, VD5 and cl , which is used for integrated block The beat signal output by the beat output terminal Ps of the integrated block is controlled by
the delay link composed of C3 and R5 to control the on and off of the thyristor vs. Adjusting the values ​​of C3 and R5 can change the duration of the flash
. The music signal output by the integrated is amplified by the triode VT through the OUT output, pushing the piezoelectric ceramic piece B to emit pleasant electronic music sounds.
