The electronic rodent repeller circuit is composed of the high voltage generating circuit and music alarm circuit, and the circuit is shown as the chart. High-voltage generating circuit is composed of the power switch S, light EL, indicator light HL, power transformer T, relay K and high voltage power grid. Music alarm circuit is composed of the music integrated circuit IC, transistor V, capacitors C1, C2, diodes VD1 ~ VD4 and speaker BL. Turning on the power switch S will make AC 220V voltage be limited by EL, transformed by T. And then it will generate 2kV high AC voltage on the winding W2 of T, and the voltage is added on high voltage electrified wire netting by the relay K; W3 winding generates 3.5V AC voltage and rectified by the VD1 ~ VD4, filtered by C1 to provide operating voltage for the IC at the same time of HL being lit.
