Loud and compact ,Plastic House materials,A slight and thin brass Element which plays an important role in the producing sound can be seen through the hole.This kind of self-drive type buzzer operates at DC voltage.

This buzzer can produce the sound for panel mount buzzers, household goods, medical devices and even very loud sirens. When a lower frequency is required an electromagnetic buzzer can fill the need.

This piezo transducer contains no electronics but will transform Ac voltages to sound pressure waves Ear-shaped with lead type.It has ear-like shape, black plastic housing, mono lead type. When subjected to an alternating electric field they stretch or co
