The sound source of the piezoelectric buzzer sound element mainly comes from the piezoelectric diaphragm. The piezoelectric vibrating plate is composed of a piezoelectric ceramic plate on which electrodes are printed on both sides, and a metal plate (brass or stainless steel, etc.). Using a bonding

The piezoelectric diaphragm works on the principle of piezoelectric effect, which generates mechanical vibration when an alternating voltage is applied thereto; on the contrary, it also generates a voltage signal when a mechanical force is applied thereto. Therefore, the piezoelectric ceramic buzzer

Piezoelectric diaphram buzzer has small size, no contact, no noise, high reliability, low power consumption, low cost and good frequency characteristics. Therefore, it is widely used in alarm and vocal use of various electrical products. The most common ones are sounding devices on the small electro

1. Check the piezoelectric diaphragm: Selecting a piezo diaphragm for buzzer with good appearance and no oxidized substrate for the substrate and silver plating.2. Piezo diaphragm with tin: First, the copper/steel substrate of the piezo alarm element is tinned. Because the copper/steel substrate dis
