Title:
ULTRASONIC TRANSDUCER AND METHOD FOR MANUFACTURING ULTRASONIC TRANSDUCER
Document Type and Number:
WIPO Patent Application WO/2018/061198
Kind Code:
A1
Abstract:
An ultrasonic transducer comprises a drive unit attached to an outer periphery of a bolt in a state of being sandwiched between a front-end side block and a base-end side block with respect to a direction along a longitudinal axis. The drive unit comprises a piezoelectric element which generates ultrasonic vibrations by being supplied with electric energy. The ultrasonic transducer transmits the ultrasonic vibrations generated by the piezoelectric elements, and thereby vibrates in a state in which a mutual deviation between a first vibration node occurring in the drive unit and a second vibration node occurring in the bolt is suppressed along the longitudinal axis.
