VIBRATING DIAPHRAGM AND SOUNDER USING THE SAME

---

Abstract

---

A diaphragm and a sounder using the same are disclosed in the present disclosure. The diaphragm includes a suspension portion and a dome assembled with the suspension portion. The dome includes a polyethylene terephthalate (PET) layer, a middle layer and an adhesive layer, with the middle layer sandwiched between the PET layer and the adhesive layer. The middle layer is formed with a first through hole for adjusting the deformation amount of the diaphragm. The present disclosure can improve the flatness of the dome and prevent deformation of the dome after the vibration.
