CAPACITIVE ULTRASONIC TRANSDUCER

摘要

According to an embodiment of the present invention, a capacitive ultrasonic transducer generates a resonant frequency thereof by receiving an electrical pulse. The capacitive ultrasonic transducer comprises: an ultrasonic vibration part which is vibrated according to generation of the resonant frequency to send an ultrasonic wave; and an elastic support part which is formed in a lower portion of the ultrasonic vibration part to provide an elastic force to the ultrasonic vibration part.
