  • Piezo element with diaphragm: The alarm uses a piezoelectric element with a conical diaphragm. The size of the diaphragm can be selected from a variety of options, and the color can also be transparent or black. The piezoelectric ceramic plate can also be corrugated and ordinary. Among them, 31.8mm buzzer Sheet and 48MMPVC membrane high-pitched piezoelectric ceramic disks is the most common, we can also customize the diaphragm and Piezoelectric Diaphragms , and the diaphragm can also be made of high temperature resistance and flame retardant. The cost of customized molds is not high. If the order quantity is relatively large in the future, the mold fee can be refunded! The Piezoelectric sound components with diaphragm should be passive, and it also needs to be connected to the driving power to work. For more information of Piezoelectric Ceramic Chips with PVC, please consult FBelec engineers or sales managers.
