Ultrasonic transducer is a device that converts electrical energy into mechanical energy (ultrasonic wave). The most mature and reliable one is the device that realizes the mutual conversion of electrical energy and acoustic energy based on the piezoelectric effect, which is called piezoelectric transducer. It consists of a central piezoelectric ceramic element, front and rear metal covers, pre-stressed screws, electrode plates and insulating tubes. This kind of sandwich transducer (bolt-fastened transducer) generates stable ultrasonic waves when the load changes, and it is the most basic and main method to obtain a power ultrasonic drive source. According to different designs, they are mainly in the form of pillars (the diameter of the front and rear metal covers are the same), inverted trumpet (the diameter of the front cover is excessively reduced by the arc), the steel back cover of the pillar, and the joint in the middle of the pillar.
