Piezoelectric ceramic rings

What is a piezo ceramic disc?Piezoelectric ceramic disc, commonly known as buzzer chip, is an electronic sound element. A piezoelectric ceramic dielectric material is placed between two round copper electrodes. When an AC audio signal is connected to the two electrodes, the piezoelectric plate will

Piezoelectric ceramics refer to ferroelectric ceramics made of mixed oxides (zirconia, lead oxide, titanium oxide, etc.) after high-temperature sintering and solid-phase reaction, and through DC high-voltage polarization treatment to make it have piezoelectric effect Collectively. It is a functional

The piezoelectric effect is reversible. If an audio voltage is applied to the piezoelectric ceramic discs, mechanical vibration and sound can be generated. On the contrary, when the piezo ceramic disc is subjected to mechanical vibration (or pressure), a certain amount of charge Q is generated on th
