Siren diaphragm piezoelectric material protection device

摘要

This study is about diene, forming an elastic protective film (53) on one side of the piezoelectric material (52) equipped with a vibration plate (50), and providing a piezoelectric material protection device made of diene.Moreover, the material of the elastic protective film (53) includes rubber, synthetic rubber, soft synthetic resin, etc.This study considers that since the piezoelectric material of the vibration plate is protected by the elastic protective film, it will not be damaged due to the overload of the piezoelectric material, it has the advantages of prolonging the service life of the product, improving the reliability, reducing the incidence of after-sales service, so as to make the product management more convenient.
