Ultrasonic transducer is a device that can convert high-frequency electrical energy into mechanical energy. It is generally magnetostrictive and piezoelectric ceramic. The power output is sent to the ultrasonic generator, and then to the ultrasonic transducer. The ultrasonic derivation device can generate ultrasonic waves.
The ultrasonic transducer consists of a central piezoceramic component, a front and rear metal cover, a pre-stressed screw, an electrode pad and an insulating tube. This sandwich transducer (also known as a bolt-on transducer) produces a load change. Stable ultrasonic is the most basic and most important method to obtain power ultrasonic drive source.
According to different designs, the shape of the ultrasonic transducer mainly has a column type (the front and rear metal cover plates have the same diameter) and a horn type (the front cover plate diameter is excessively reduced by the arc shape).

Application fields of piezoelectric ceramics:
Piezoelectric ceramics is a functional ceramic material that can convert information between mechanical energy and electrical energy. Piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics also have dielectric properties, elasticity, etc., and have been widely used in medical imaging. Acoustic sensors, acoustic transducers, ultrasonic motors, etc. Piezoelectric ceramics are made by the relative stress of the internal positive and negative charge centers under the action of mechanical stress, which causes the opposite ends of the material to have oppositely bound trapped charges, ie piezoelectric effect, and has sensitive characteristics. Ceramics are mainly used in the manufacture of ultrasonic transducers, hydroacoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optic devices, In addition to being used in high-tech fields, it is used to serve people in daily life and to create a better life for people.
