Ultrasonic transducers are widely used. According to the application industries, they are divided into industry, agriculture, transportation, life, medical treatment and military. According to the realized functions, it is divided into ultrasonic processing, ultrasonic cleaning, ultrasonic detection, detection, monitoring, telemetry, remote control, etc.; according to the working environment, it is divided into liquid, gas, biological body, etc.; according to the nature, it is divided into power ultrasonic, detection ultrasonic, ultrasonic imaging, etc. .

Ultrasonic transducers are piezoelectric ceramics that resonate at ultrasonic frequencies. The piezoelectric effect of the material converts electrical signals into mechanical vibrations. The working principle of medical ultrasonic transducers (ultrasound probes) is basically the same, and its interior usually contains an electrical energy storage element and a mechanical vibration system. When the transducer is used as a transmitter, the electric oscillation signal sent from the excitation power supply will cause the electric field or magnetic field in the electric energy storage element of the transducer to change. This change will affect the mechanical vibration system of the transducer through a certain effect. A driving force is generated to enter the vibration state, thereby driving the medium in contact with the mechanical vibration system of the transducer to vibrate, and radiate sound waves into the medium. The process of receiving sound waves is just the opposite. External sound waves act on the vibrating surface of the transducer, thereby causing the mechanical vibration system of the transducer to vibrate. With the help of a certain physical effect, it causes the electric field or the energy storage element of the transducer. The magnetic field changes accordingly, causing the electrical output of the transducer to generate a voltage and current corresponding to the acoustic signal.

Ultrasonic vibrators (ultrasonic transducers) such as 28KHZ/40KHZ/25KHZ/68KHZ/80KHZ/120KHZ/200KHZ are widely used in the electronics industry, machinery industry, automobile, electroplating, chemical fiber,
Optical, bearing and other industries. For example, cleaning magnetic cores, oil nozzles, auto parts, electroplating hardware tools, chemical fiber spinnerets, optical lenses, bearings, tools, tableware, medical equipment, precision hardware, watch parts, gold and silver jewelry, electronic components. The frequency vibration is strong and the density is uniform. It can quickly achieve the purpose of degreasing, sodium removal, decontamination, and descaling. In addition, it can also be used in chemical experiments to achieve catalysis, stirring, and rapid generator chemical reactions.
