What are the main characteristics of piezoelectric ceramic buzzer? Piezoelectric ceramic buzzer is a kind of device used in piezoelectric ceramic chip. Titanium and piezoelectric ceramic sheets (PZT) made of zirconium and lead oxides are commonly sintered. In order to improve the low-frequency response, double diaphragm structure is generally used.

Piezoelectric ceramic buzzer is widely used and matched in electronic clocks and watches, car horns, sound, communication, remote sensing, calculators, electronic toys and other products.
1. High sensitivity and low energy consumption;
2. Good reliability and stability;
3. High and low temperature resistance and long service life;
4. Thin thickness and light weight;
5. Small size, high pressure resistance.
