1. If the piezoelectric ceramic piece has been bonded to the copper , what should I do? In addition, about the capsulation, how to choose? For the first problem, the processing method of piezoelectric discs crystal is very simple. Just test whether the curie temperature of the piezoel

1. What are the specific applications of piezoelectric ceramics?(1) The piezoelectric discs transducer is sensitive to this characteristic, and it can convert mechanical vibration into an electrical signal. Therefore, it can be used well in such fields as sonar systems, weather detection, and teleme

Piezoelectric diaphram buzzer has small size, no contact, no noise, high reliability, low power consumption, low cost and good frequency characteristics. Therefore, it is widely used in alarm and vocal use of various electrical products. The most common ones are sounding devices on the small electro

Piezo element film buzzer In general, a human's audio range is between approximately 20 Hz and 20 kHz. The most audible audio is 2kHz to 4kHz.Therefore, most piezoelectric sound elements are used in this audio range. At the same time, the buzzer resonance frequency (f0) is generally selected to be

The sound source of the piezoelectric element buzzer sound element mainly comes from the piezoelectric diaphragm. The piezoelectric vibrating plate is composed of a piezoelectric ceramic plate on which electrodes are printed on both sides, and a metal plate (brass or stainless steel, etc.). The adhe
