Piezo Buzzer
Piezo Buzzer
The piezoelectric ceramic buzzer is a device of the application of piezoelectric ceramics. Titanium and piezoelectric ceramics (pzt) are commonly made by sintering zirconium and lead oxides. Because human ears are most sensitive to 3kHz audio signals, the resonant frequency of buzzer is usually designed at about 3kHz in production. In order to improve the low frequency response, the double diaphragm structure is generally used. Widely used and matched in electronic clocks, car horns, audio, communications, remote sensing, calculators, electronic toys and other products.
