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.
