Abstract
The present disclosure provides diaphragm, which includes a dome part, a suspension part supporting the dome part, an adhesive layer located between the dome part and the suspension part. The suspension part includes a supporting portion for supporting the dome part and a periphery extending from and surrounding the supporting portion. The dome part further includes a first ceramic layer, a damping layer attaching to the supporting portion via the adhesive layer. By virtue of the configuration of the dome part, the diaphragm has better damping performance and greater stiffness. In addition, by virtue of the ceramic layer, the diaphragm is provided with better heat-stability.
