Abstract: Disclosed is a sound production device including a housing and a vibration assembly, the vibration assembly comprising a vibration diaphragm and a voice coil combined to one side of the vibration diaphragm; wherein the sound production device further comprises a system stabilization component connected with the voice coil; the system stabilization component is of a line-like structure formed by winding a metal wire, and comprises a first connection part connected to the voice coil, a deformation part, and a second connection part connected to the housing. By adopting the sound production device of this structure, the voice coil will not be polarized under the condition of large displacement, and the system stabilization component having a novel structure does not hinder the free vibration of the voice coil either.

Abstract: The present disclosure discloses a silica gel vibrating diaphragm and a method for fabricating the same. The method comprises: forming a composite material belt by using two layers of a base material and liquid silica gel in a calendering manner, wherein the liquid silica gel is between the two layers of the base material; wholly hot-press molding the composite material belt by a vibrating diaphragm die holder, a temperature of the hot-press molding being higher than a vulcanization temperature of the liquid silica gel; removing the two layers of the base material to obtain a whole sheet of silica gel vibrating diaphragm; and blanking the whole sheet of silica gel vibrating diaphragm that has been removed of the two layers of the base material to fabricate a required silica gel vibrating diaphragm. As compared with conventional solutions, the technical solution of the present disclosure has the advantages of simple molding manner, low cost, various styles of the vibrating diaphragm, and small thickness of the vibrating diaphragm.

Abstract: A silica gel diaphragm, a receiver module, and a method for processing a silica gel diaphragm. Two metal pieces are integrally injection-molded on the diaphragm, and symmetrically embedded into the diaphragm, and either end of each of the metal pieces is provided with first and second soldering portions; each of the first soldering portions is embedded into a planar portion of the diaphragm, and is used for soldering a winding tap of a voice coil on an inner side of the voice coil; each of the second soldering portions protrudes from or is embedded into the fixing portion of the diaphragm, and is used for soldering a bonding pad on a housing; and middle portions connecting the first soldering portions and the second soldering portions are embedded into the diaphragm to form an electrically conductive path. This technical solution increases the product stability.

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.

Abstract: A silica gel diaphragm, a speaker module, and a method for reprocessing a silica gel diaphragm. Two symmetrical wire grooves are etched on a surface of the silica gel diaphragm by laser etching technique, an electrically conductive metal layer is deposited in each of the grooves, and either end of each of the metal layers includes a first and second soldering portions. Each of the first soldering portions is deposited on a planar portion of the silica gel diaphragm, and is used for soldering a winding tap of a voice coil on an inner side of the voice coil. Each of the second soldering portions is deposited on a fixing portion of the silica gel diaphragm, and is used for soldering a bonding pad on a housing. Middle portions connecting the first soldering portions and the second soldering portions are deposited in the diaphragm to form an electrically conductive path.
