Piezoelectric ceramic disc is an acoustic element, divided into single-sided plate (only one side has ceramic layer) and bimorphe (both sides have ceramic layer). Single-sided disc contains double electrodes and three electrodes. Among the piezoelectric buzzers we produce, the piezo element is the most important sound element. It is widely used in piezoelectric buzzer, alarm siren, tweeter. The normal frequency range is 2000Hz to 4000Hz. Of course, we can also customize it according to customer requirements.

The key point of purchasing piezoelectric ceramic disc is to clearly know its frequency, copper thickness, and ceramic layer thickness. With this information, we can quickly match you with the appropriate piezo transducer .
