China Manufacture 20K PZT8 Piezoelectric Ceramic Ultrasonic Transducer For Non-woven Ultrasonic Welding

The ultrasonic vibrator is also called the ultrasonic vibrator, and the whole after connecting the transducer and the horn is called the vibrator. It is a device that realizes the mutual conversion between electrical energy and mechanical energy (acoustic vibration) by the piezoelectric effect of piezoelectric ceramics, and is amplified by the front and rear radiation cover blocks that match the acoustic impedance.
Since the horn is a passive device, it does not produce vibration itself, but transmits the input vibration after changing the amplitude, completing the impedance transformation.
Ultrasonic transducers can produce regular vibration under electric field excitation, but the amplitude is generally about 10μm. Such amplitude is not enough to directly complete the welding and processing procedures.
Therefore, after the transducer is connected to a reasonably designed horn, the amplitude of the ultrasonic wave can be changed in a large range, as long as the material strength is sufficient, the amplitude can exceed 100 μm.
