Abstract
A diaphragm, including: a metal dome, a non-metallic diaphragm portion, and a flexible rim. The non-metallic diaphragm portion is bonded to a metal dome outer periphery, and a non-metallic diaphragm portion outer periphery extends corresponding to a convex direction of the metal dome and expands radially away from the metal dome. The flexible rim is bonded to the non-metallic diaphragm portion outer periphery. The diaphragm of the present application adopts the combination of the metal dome, the non-metallic diaphragm portion, and the flexible rim, the overall rigidity of the diaphragm is enhanced, and the internal damping property of the diaphragm and the compliance of the vibration of the diaphragm can be adjusted, which can effectively reduce segmentation vibration of the diaphragm during high-frequency vibration and reduce the segmentation distortion of the diaphragm at high frequencies, thereby extending the bandwidth of the diaphragm.
