Electronic sound imitation rodent repeller
Cats are predators of rats, it's an effective method which utilizing electronic devices to simulate meows to flood mouse. As it's an electronic device, the voice of meows could be fast or slow, the interval time may be long or short, and circuit structure is simple, cheap. It's suitable for electronic enthusiasts for homemade and applied in family. The working principleis shown in 1. It is composed of time control circuit, meow generation circuit, power amplifier circuit.etc. Time control circuit is composed of time-base circuit IC1 NE555 and Peripheral RC components, diodes and other components. It is a duty ratio adjustable pulse oscillator, the duty ratio is controlled by the R2 and R3. Meow circuit is a type of CMOS integrated circuit IC2 KD-5605, it uses storage technology to solidify meows in the interior of circuit. Power amplifier utilizes cheap and low-power audio amplifier integrated circuit IC3 LM386. Its features are few external components, wide voltage range, small distortion, simple assembly. (View)
