NATURAL ULTRASONIC WAVES GENERATOR

摘要

An ultrasonic generator is provided, which generates the audio frequency and the high frequency and low frequency which are in a range except the audio frequency. An ultrasonic generator comprises: a signal generator(410) generating the ultrasonic signal and low frequency signal; a modulator(420) for modulating the sound wave signal generated in the signal generator; an amplifier(430) for amplifying the sound wave signal outputted in the modulator; a sound wave generating unit(200) generating the sound wave; and a receiving member receiving the sound wave generating unit and the signal generator.
