Products are widely used in many fields such as ultrasonic cleaning, welding, detection, medical B-ultrasound, beauty equipment, hydro-acoustic transducer, micro-drive, ultrasonic flowmeter and so on.

The principle of the piezoelectric ceramic transducer is that when pressure or tension is applied to the ceramic chip, charges of opposite polarity are generated at the two ends of the ceramic chip, and a current is generated through the circuit. This effect is called the piezoelectric effect. Therefore, in the design of ultrasonic transducers, various factors should be considered, such as acoustic impedance, frequency response, impedance matching, acoustic structure, vibration mode and conversion materials, and how to design and coordinate these factors to achieve electro-acoustic conversion. best value. As a kind of energy transmission network, piezoelectric ceramic transducer has the problem of energy conversion efficiency.
The conversion efficiency is related to the selection of the transducer material, the form of vibration, the structure of the mechanical vibration system (including the support mechanism), and the operating frequency. Therefore, the problem of the ultrasonic transmitter is solved. There are two materials for piezoelectric ceramic transducers: magnetostrictive metal and piezoelectric ceramics. Piezoelectric ceramic transducer is an electronic ceramic material with piezoelectric characteristics. The main difference from a typical piezoelectric quartz crystal that does not contain ferroelectric components is that the main component of the crystal phase is all ferroelectric crystal grains. Ceramics are polycrystalline aggregates with randomly oriented grains, so the spontaneous polarization vector of each ferroelectric grain is also disoriented.
If a transducer made of such piezoelectric ceramics is put into water, then under the action of sound waves, charges will be induced at both ends of the transducer, which is a sound wave receiver. In addition, the piezoelectric effect is reversible. If an alternating electric field is applied to a piezoelectric ceramic sheet, the ceramic sheet will become thinner and thicker from time to time, and it will vibrate and emit sound waves. In order to make the ceramic exhibit macroscopic piezoelectric properties, the piezoelectric ceramic must be polarized in a strong DC electric field after firing, and the end face is subjected to multiple electrodes, so that the polarization vector of the original disordered orientation is preferentially oriented in the direction of the electric field, and after the electric field is eliminated , The piezoelectric ceramic after polarization treatment will maintain a certain macroscopic residual polarization strength, so that the ceramic has a certain pressure.

Piezoelectric ceramics is a kind of information functional ceramic material that can convert mechanical energy and electrical energy to each other-piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics also have dielectric and elastic properties. It has been widely used in medical imaging and acoustic sensors. , Sound transducer, ultrasonic motor, etc. Piezoelectric ceramics are made by using their materials to cause the relative displacement of the positive and negative charge centers inside the material under the action of mechanical stress to be polarized, which leads to the occurrence of bound charges with opposite signs on both ends of the material, that is, the piezoelectric effect. It has sensitive characteristics. Ceramics are mainly used to manufacture ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic discriminators, high-voltage generators, infrared detectors, surface acoustic wave devices, electro-optical devices, In addition to being used in high-tech fields, ignition and detonation and piezoelectric gyroscopes are used to serve people in daily life and work hard to create a better life for people.
