ABSTRACT:
An electronic rodent repelling device includes a housing electrically coupled to an existing power supply source of the vehicle, a power conditioning circuit for receiving an input voltage signal from the existing power supply source, and a signal generator electrically coupled directly to the power conditioning circuit. The device further includes an amplifier electrically coupled directly to the signal generator for receiving the output signal and thereafter transmitting an amplified signal, and an ultrasonic transducer electrically coupled directly to the amplifier for emitting an ultrasonic output signal based upon receipt of the amplified signal.
