The circuit is shown as the chart. It consists of multivibrator, graphics driver circuit, AC solid-state relay control circuit, music sound circuit, audio amplifier circuit and the AC voltage regulator rectifier circuit. It can produce changing patterns lantern and accompanied by beautiful music. Time-base circuit 555 and R1, RP1, RP2, C1 form a non-steady-state multivibrator, as the VD1, VD2 are added, the charging and discharging circuits are different, and changing the RP2 and RP1 can adjust its charging and discharging loop, which can change the charging and discharging rate.
