Abstract:
1. An electromagnetic vibrator, comprising: an electromagnetic provider for generating a magnetic field; and a vibration unit coupled with said electromagnetic provider, comprising: a diaphragm unit which comprises a diaphragm layer and a vibration layer integrally affixed at a center portion of said diaphragm layer; and an induction coil unit which is affixed to an inner side of said diaphragm unit, wherein said induction coil unit is electromagnetically inducted with said magnetic field of said electromagnetic provider to drive said induction coil unit to move in an axially movable manner so as to generate a vibration force in an axially movable manner at said diaphragm unit, wherein said diaphragm layer has a suspension edge portion, wherein said vibration layer is integrally affixed to said diaphragm layer within said suspension edge portion thereof, wherein an outer surface of said vibration layer is integrally affixed to said center portion of said diaphragm layer to match a curvature of said vibration layer with a curvature of said diaphragm layer at said center portion thereof.
