Title:
ULTRASONIC TRANSDUCER AND METHOD FOR PRODUCING ULTRASONIC TRANSDUCER
Document Type and Number:
WIPO Patent Application WO/2018/061199
Kind Code:
A1
Abstract:
An ultrasonic transducer provided with a drive unit attached to the outer circumference of a bolt in a state of being sandwiched between a block on the front-end side and a block on the base-end side in a direction along the longitudinal axis, the drive unit being provided with a piezoelectric element that generates ultrasonic vibration by being supplied with electric energy. A single unit of the ultrasonic transducer is caused to vibrate with a prescribed resonant frequency by a pressing force from the front-end-side block to the base-end-side block and/or the shape of a block extension part of the base-end-side block that is extended from the base end of the bolt to the base-end side.
