Ultrasonic transducer:

A device that converts high-frequency electrical energy into mechanical energy, typically magnetostrictive and piezoceramic. Power output to the ultrasonic generator, and then to the ultrasonic transducer, the general also go through the ultrasound export, the receiving device can produce ultrasound.

Composition of ultrasonic transducers:

The utility model comprises an outer shell, a matching layer that is an acoustic window, a piezoelectric ceramic disc transducer, a backing and a lead cable. The utility model is characterized in that the utility model also comprises an array receiver which is composed of a lead cable, a transducer, a metal ring and a rubber washer .

Ultrasonic transducer principle and role:

An ultrasonic transducer is a piezoelectric ceramic that resonates at an ultrasonic frequency and converts an electric signal into a mechanical vibration by the piezoelectric effect of the material. The ultrasonic transducer is an energy conversion device whose function is to convert the input electric power into The mechanical power (ie, ultrasound) is passed out again, which itself consumes a small fraction of the power. Ultrasonic transducer types: can be divided into piezoelectric transducer, sandwich transducer, cylindrical transducer, inverted horn transducer and so on.
