  • Sound capability of piezoelectric elements: Piezoelectric buzzer is designed to enable product manufacturers to produce sound in their own shell and shell design, FBelec has special professional knowledge and more than 20 years of production experience in the production of piezoelectric components, ranging from 10mm size for sensors to very large units for alarms. The specially formulated piezoelectric ceramic disc is suitable for various base disc materials to adapt to most applications. Piezoelectric disc is a low-cost and low-power solution, which can produce good sound output in specific medium and high frequency band. When combined with a plastic cone or layered in a bimorph structure, the piezoelectric sheet can become a very powerful sound generator. Our catalogue of special piezoelectric components contains more information about piezoelectric components and piezoelectric technology. For more information, please contact the technical and sales personnel of FBelec!
