The principle of piezoelectric ceramic transducer is that when pressure or tension is applied to the ceramic plate, opposite polarity charges will be generated at both ends of the ceramic plate, and current will be generated through the circuit. This effect is called piezoelectric effect. Therefore, in the design of ultrasonic transducers, various factors, such as acoustic impedance, frequency response, impedance matching, acoustic structure, vibration mode and conversion materials, should be considered, as well as how to design and coordinate these factors to achieve the optimal value of electroacoustic conversion. As an energy transmission network, piezoelectric ceramic transducer has the problem of energy conversion efficiency.

The conversion efficiency is related to the selection of transducer material, vibration form, structure of mechanical vibration system (including support mechanism) and working frequency. Therefore, the problem of ultrasonic transmitter is solved. Piezoelectric ceramic transducer has two materials: magnetostrictive metal and piezoelectric ceramic. Piezoelectric ceramic transducer is a kind of electronic ceramic material with piezoelectric characteristics. The main difference between the piezoelectric ceramic transducer and the typical piezoelectric quartz crystal without ferroelectric component is that the crystal phase of its main component is ferroelectric crystal Because ceramics are polycrystalline aggregates with randomly oriented grains, the spontaneous polarization vector of each ferroelectric grain is also disoriented.

If the transducer made of this piezoelectric ceramic is put into water, then under the action of sound wave, charges will be induced at both ends of the transducer, which is a sound wave receiver. In addition, the piezoelectric effect is reversible If the alternating electric field is applied to the piezoelectric ceramic sheet, the ceramic sheet will become thinner and thicker from time to time, and generate vibration and sound waves. In order to make the ceramics show macroscopic piezoelectric characteristics, the piezoelectric ceramics must be polarized in a strong DC electric field after firing, and the end faces are subjected to multiple electrodes, so that the polarization vector of the original disordered orientation is preferentially oriented in the direction of the electric field. After the electric field is eliminated, the piezoelectric ceramics after polarization treatment will maintain a certain macroscopic residual polarization strength, so that the ceramics will have a certain pressure.
