Ultrasonic transducer is an energy device that realizes the conversion of electrical energy, mechanical energy or sound energy from one form of energy to another. It is also called an ultrasonic transducer, or an active sensor. Among them, the more mature and reliable device is the piezoelectric effect to realize the mutual conversion of electric energy and sound energy, also known as piezoelectric transducer.

Ultrasonic transducer, including housing , matching layer or acoustic window , piezoelectric ceramic disc transducer , backing , lead cable , characterized in that it also includes Cymbal array receiver, which is composed of lead-out cable , 8-16 Cymbal transducers , metal rings , and rubber gasket ; Cymbal array receiver is located on the disc The piezoelectric ceramic disc transducer is used as the basic ultrasonic transducer, which transmits and receives ultrasonic signals; the Cymbal array receiver is located on the disc piezoelectric transducer, As an ultrasonic receiver, it is used to receive Doppler echo signals outside the frequency band of the disc transducer.

The role of the transducer is to convert electrical signals into mechanical vibration signals. There are two physical effects in converting electrical signals into mechanical vibration signals. a: Magnetostrictive effect. b: The reverse effect of the piezoelectric effect. Magnetostrictive effect is often used in early ultrasonic applications. Its advantage is large achievable power capacity, but its disadvantage is low conversion efficiency, difficulty in manufacturing, and difficulty in mass industrial production. Since the invention of the piezoelectric ceramic transducer, the application of the inverse effect of the piezoelectric effect has been widely adopted. Piezoelectric ceramic transducers have the advantages of high conversion efficiency and mass production, but the disadvantage is that the power capacity is small. Existing ultrasonic machines usually use piezoelectric ceramic transducers. Piezoelectric ceramic transducers are made by sandwiching piezoelectric ceramics between two metal front and rear load blocks and tightly connecting them with screws. The output amplitude of a typical sensor is about 10μm.
