The piezo diaphragm film, also called piezoelectric ceramic buzzer,which is one of the most widely used products in piezo alarm element. The piezo diaphragm buzzer is the main component of the piezo disc benders. The piezoelectric buzzer is made of lead zirconate titanate or lead magnesium niobate p

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
