 Piezoelectric Ceramic
 

When the voltage is applied to the piezoelectric ceramics, the mechanical deformation will occur with the change of the voltage and frequency. On the other hand, when vibrating piezoelectric ceramics, will produce a charge. According to this principle, when the vibrator is composed of two piezoelectric ceramic or a form of piezoelectric ceramic and a metal sheet, called bimorph element, applying a signal, it will emit ultrasonic vibration due to bending. In contrast, when an ultrasonic vibration is applied to the bimorph element, an electrical signal is generated. Based on the above, the piezoelectric ceramics can be used as ultrasonic sensors.
 
 The piezoelectric ceramic wafer is electrical devices with a simple structure and light, with high sensitivity, no magnetic field spread without spillover, copper wire and magnets, low power consumption, less cost, easy mass production and the advantages of widely used. Suitable for ultrasonic and acoustic wave transmitting and receiving, piezoelectric ceramics is relatively large area and can also be used to detect pressure and vibration. The working principle is to use the reversible piezoelectric effect, applied voltage in the audio, and voice.

Descriptio Piezoelectric Ceramic:
 
◊ High efficiency: high mechanical parameter Q, the transduction efficient between electricity and sound above 95%.
◊ High amplitude: the transducer strength is improved by fixing the high speed vibrator directly on the base of washing groove with bolt. Compare with a magnetic expansion vibrator, its amplitude can be improved above 50%.
◊ Good heat resistance: a large range of working temperature, low resonance impedance and heat productivity.
◊ Good construction: fastened by bolt, easy for assembling, high reliability.
