Piezo Siren Waterproof IP67 with Square Brackets

Piezoelectric alarm is a device that works on the principle of piezoelectric effect. It mainly converts electrical energy into mechanical vibration to generate sound. Piezoelectric effect refers to the fact that some materials will generate electric charge when subjected to mechanical pressure or stretching. Conversely, when these materials are subjected to electric field, they will also produce corresponding mechanical deformation.In addition to alarm, receiver、 buzzer、 speaker and other electroacoustic devices are our main products.
