Vibration transducer with piezoelectric element

Abstract

Claims of piezoelectric element, and voltage signal transmitting the electric signal and back conversion, wherein with porous isotropic ceramic body and at least two connecting the electrode the ceramic body. The porous ceramic body with filling hole, and easiest is elastic layer and sealed in the whole surface. In addition, further claims for with a arranged in the shell piezoelectric element the vibration converter. The ear rigid connection of piezoelectric element on shell substrate. The other end face pressure-sensitive chip the surface, and better transversely symmetrically distributed cover of the shell. The volume of the shell is of the composite of tubular, piezoelectric element and are parallel and mechanical.
