The basic principle of ultrasonic transducer?

A brief introduction of ultrasonic transducer

Ultrasonictransducer, named as Ultrasonictransducer, is an energy conversion device that converts high frequency electric energy into mechanical energy. It is often used in ultrasonic cleaning machine, ultrasonic welding machine, trichlorination machine, gas camera and other equipment, in agriculture, industry, life, transportation, military, medical and other fields have been widely used.

Two, ultrasonic transducer structure

Ultrasonic transducer mainly consists of shell, sound window (matching layer), piezoelectric ceramic disk transducer, backing, lead cable, Cymbal array receiver and so on. Among them, the piezoelectric ceramic disc transducer plays the same role as the general transducer, mainly used for transmitting and receiving ultrasonic waves; And above the piezoelectric ceramic disk transducer is the Cymbal array receiver, which is mainly composed of the lead cable, the Cymbal transducer, the metal ring and the rubber washer, used as an ultrasonic receiver, to accept the Doppler callback signal generated outside the frequency band of the piezoelectric ceramic disk transducer.

Three, the principle of ultrasonic transducer

Ultrasonic transducers, which are piezoelectric ceramics at the same frequency as their resonance, use the material's piezoelectric effect to convert electrical energy into mechanical vibration. In general, the ultrasonic wave is first produced by the ultrasonic generator, which is converted into mechanical vibration by the ultrasonic transducer, and then produced by the ultrasonic export device and the ultrasonic receiving device.
