The principle of the piezoelectric ceramic transducer is that when pressure or tension is applied to the ceramic chip, charges of opposite polarity will be 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 material, 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 components of the crystal phase are 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 this piezoelectric ceramic 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. , The piezoelectric ceramic after
polarization treatment will maintain a certain macroscopic residual
polarization strength, so that the ceramic has a certain pressure.
