When the power is connected, the astable multivibrator begins to work. IC1’s 7 pin will output 11Hz oscillator signal. After the signal is transformed into sawtooth wave by V, it will output 18-30kHz sweep frequency signal from IC2’s 4 pin after IC2’s control and process. The signal will force HA to emit ultrasonic beam of 100dB after TWH68’s amplification and boost. The ultrasonic beam can then drive awaymice or pests in a certain area.
