Title:
SILICA GEL DIAPHRAGM, RECEIVER MODULE, AND METHOD FOR PROCESSING SILICA GEL DIAPHRAGM
Document Type and Number:
WIPO Patent Application WO/2016/169283
Kind Code:
A1
Abstract:
Disclosed are a silica gel diaphragm, a receiver module, and a method for processing a silica gel diaphragm. Two metal pieces are integrally injection moulded and formed on the silica gel diaphragm, the two metal pieces are symmetrically embedded within the silica gel diaphragm, and two ends of each metal piece are provided with a first solder portion and a second solder portion. Each first solder portion is embedded in a planar portion of the silica gel diaphragm, said planar portion being near to a folding ring portion, and is used for soldering a winding tap of a voice coil at an inner side of the voice coil. Each second solder portion extends out from a fixing portion of the silica gel diaphragm or is embedded in said fixing portion, and is used for soldering a solder pad on a housing. Central portions connecting the first solder portions and the second solder portions are embedded within the silica gel diaphragm to form a conductive path. Via the technical solution wherein the two metal pieces of the silica gel diaphragm replace voice coil lead wires, the present invention completely solves the problem of poor listening caused by voice coil lead wire collision, and the metal pieces injection moulded within the silica gel diaphragm also prevent the risk of voice coil lead wire breakage, increasing product stability.
