Abstract: Disclosed is a linear vibration motor, comprising a vibrator and a stator, the vibrator comprises a counterweight block and a vibration block, the vibration block includes at least two magnets adjacently arranged and a magnetic conductive yoke disposed between any two adjacent magnets, and polarities of adjacent ends of two adjacent magnets are the same. The magnets are any combination of a permanent magnet and/or an electromagnet. The stator includes a stator coil disposed at one side, or upper and lower sides of the vibrator, and a magnetic conductive core disposed in the stator coil, and the axis direction of the stator coil is perpendicular to the magnetization direction of the magnets. The linear vibration motor adopts free combinations of permanent magnets and electromagnets to constitute the vibration block, and thus expands the implementation manners of the linear vibration motor so as to improve the flexibility in the production process.

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.
