DC voltage of about 3V, the manifold A supply of electricity. Manifold output of the beat the beat signal Ps output from C3, R5 configured to control a part of the delay of the SCR vs turned on and off. C3 and R5 values can be adjusted to change the duration of the flashing between. Manifold music signal output from the OUT output by the transistor VT zoom, push the piezoelectric ceramic sheet B makes a musical movement listening to electronic music sound.
