Ultrasonic welding machine piezoelectric ceramic chips 15khz

Description:

When voltage is applied to piezoelectric ceramics, mechanical deformation will occur with changes in voltage and frequency. On the other hand, when the piezoelectric ceramic is vibrated, an electric charge is generated. Using this principle, when an electrical signal is applied to a vibrator composed of two piezoelectric ceramics or a piezoelectric ceramic and a metal sheet, so-called bimorph element, ultrasonic waves will be emitted due to bending vibration. On the contrary, when ultrasonic vibration is applied to the piezoelectric bimorph element, an electrical signal is generated. Based on the above effects, piezoelectric ceramics can be used as ultrasonic sensors.

Applications:

Piezoelectric ceramic chip is an electronic sound element. Piezoelectric ceramic dielectric material is placed between two copper circular electrodes. When an AC audio signal is connected to the two electrodes, the piezoelectric chip will frequency according to the size of the signal. When vibration occurs, a corresponding sound is produced. Piezoelectric ceramic sheets are widely used in electronic appliances such as toys, pronunciation electronic watches, electronic instruments, electronic clocks, timers, etc. due to their simple structure and low cost.
