Abstract:
The present application discloses a method for reprocessing a vibrating diaphragm, a vibrating diaphragm and a telephone receiver. The method for reprocessing a vibrating diaphragm involves the use of a vibrating diaphragm that includes a plane portion located at a center, a corrugated rim portion disposed at an edge of the plane portion, and a fixing portion connected to a periphery of the corrugated rim portion to bond a housing. The method includes, but is not limited to performing surface sputtering on part of an area of the corrugated rim portion by using a magnetron sputtering technology.
