ULTRASONIC TRANSDUCER, ULTRASONIC TRANSDUCER ARRAY, AND ULTRASONIC DEVICE
摘要:
An ultrasonic transducer is configured to transmit and receive ultrasonic waves. The ultrasonic transducer includes a vibrating member and a piezoelectric member coupled to the vibrating member. The piezoelectric member includes a first piezoelectric part configured and arranged to be deformed by applied voltage to vibrate the vibrating member or configured and arranged to be deformed by vibration of the vibrating member to produce a potential difference, and a second piezoelectric part configured and arranged to be deformed by applied voltage to statically deflect the vibrating member.
