Ultrasonic piezoelectric ceramic transducer is an energy conversion device. Its function is to convert input power into mechanical power (i.e. ultrasound) and then transmit it, while its power consumption is very low. Ultrasonic transducer is a device that produces sound beyond the range of human hearing, typically starting at 20 kHz, also known as ultrasonic vibration.
The ultrasonic generator converts 110VAC or 220VAC power current into high-frequency current and transmits it to the piezoelectric ceramic. Piezoelectric ceramics resonate at ultrasonic frequencies. The piezoelectric effect of materials converts electrical signals into linear mechanical vibrations. Then amplify (reduce) the amplitude through an ultrasonic horn, and finally transmit it to the tool head for operation.

Ultrasonic digital generators work by converting electrical energy into high-frequency sound waves through a process called piezoelectricity. The generator consists of a transducer, a power source, and a control unit. The transducer is a small device that converts electrical energy into mechanical vibrations. The power source provides the electrical energy to the transducer, and the control unit regulates the frequency and intensity of the sound waves.
When the electrical energy is applied to the transducer, it undergoes deformation, which creates mechanical vibrations. These vibrations are then transmitted to a cleaning solution, which creates microscopic bubbles that implode, producing a powerful cleaning action. The high-frequency sound waves also create heat, which can be used for welding or cutting materials.
Ultrasonic digital generators are powerful devices that have become an essential tool in many industries. They provide a cost-effective and eco-friendly solution for various applications, from cleaning to cutting and welding. Understanding how these devices work can help us appreciate their power and potential to improve our daily lives.
The ultrasonic transducer is mainly composed of a central piezoelectric ceramic element, front and rear metal cover plates, prestressed screws, electrode plates, and insulating tubes.
Back (rear) driver: a thick cylindrical component located on the back of the piezoelectric transducer. The driver at the back is adjacent to the ceramic at the back and is usually preloaded with a stacked bolt.
Electrode pad: a thin conductive disk placed between adjacent piezoelectric ceramics of a transducer. The driving voltage of the transducer is applied between these electrodes.
Front driver: transfers the ultrasonic energy of the transducer to the horn or tool head, and the front driver device usually includes a mounting flange for connecting the housing.
Stacked bolt: a bolt used to clamp ceramics between the front and rear drivers, forming a resonant unit. When the bolt is tightened, it applies a compressive prestress to the ceramic.
Piezoelectric ceramics: Piezoelectric ceramics are the core of transducers. A component that converts the electrical signal of an ultrasonic generator into linear mechanical vibration.
