When the switch of AN is pressed, CIC2851 is triggered to work, the output terminal (3-pin) launches music signals. After the music signals are BG1 and BG2 is magnified, the loudspeaker makes music. In the meantime, the dual controllable silicon SCR is conducting and the fancy lantern is glowing with the change of the music. By adjusting W, the performing time of the circuit is changed, i.e the flashing time of the fancy lantern is changed.
