COMPOSITE DIAPHRAGM

摘要

A composite diaphragm is provided to include a base layer and a micro-nanometer ceramic layer disposed on the surface of the base layer. The micro-nanometer ceramic is a structural material that has great stiffness and toughness, such that the composite diaphragm made of micro-nanometer ceramic manifests characteristics of high stiffness, high toughness, and great ductility. Thus, the composite diaphragm allows large deformation at room temperature to achieve high capability of producing high-definition tone.
