Piezoelectric Element piezo ceramic disc in Beauty Equipment , Vibration Componets

When the voltage is applied to the piezoelectric ceramic, it will produce mechanical deformation with the change of the voltage and frequency. On the other hand, when the vibration piezoelectric ceramic, it 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. On the contrary, when ultrasonic vibration is applied to the piezoelectric element, an electrical signal is generated. Based on the above function, the piezoelectric ceramic can be used as an ultrasonic sensor.

Description 

◊ 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.
