Embodiment Construction

[0036] Considering the forming method of the traditional diaphragm, it is only possible to connect the voice coil and the pad with the lead wire in a straight line, so the problem of the collision of the voice coil lead wire cannot be completely solved. The invention creatively injects the metal sheet into the silicone diaphragm, and replaces the lead wire of the traditional voice coil with the metal sheet to connect the welding pad along the line.

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] figure 1 It is the front view of the silicone diaphragm provided by the embodiment of the present invention. The silicone diaphragm includes a planar part 1 in the center, a ring part 2 arranged on the edge of the planar part 1, and a ring part connected to the periphery of the ring...

Abstract

The invention discloses a silicone vibrating diaphragm, a receiver module and a method for processing the silicone vibrating diaphragm. Two blocks of sheet metal are integrally formed on the silicone vibrating diaphragm through injection molding, the two blocks of sheet metal are embedded in the silicone vibrating diaphragm symmetrically, and both ends of each sheet metal are provided with a first welding part and a second welding part; each first welding part is embedded in a plane part, close to a folded ring part, of the silicone vibrating diaphragm, and is used for welding a coiling tap of a voice coil on the inner side of the voice coil; each second welding part extends out of or is embedded in a fixing part of the silicone vibrating diaphragm, and is used for welding a welding pad on an outer shell; and a connecting part connecting each first welding part and the corresponding second welding part is embedded in the silicone vibrating diaphragm to form a conductive path. By adopting the technical scheme of replacing lead wires of the voice coils with the two blocks of sheet metal of the silicone vibrating diaphragm, the problem of poor listening effect caused by collision of lead wires of the voice coils can be solved thoroughly, a wire-break risk of the lead wires of the voice coils can be avoided through the sheet metal embedded in the silicone vibrating diaphragm, and the product stability is improved.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a silicone diaphragm, a receiver module and a method for processing the silica gel diaphragm. Background technique [0002] The voice coil of the existing receiver module must be connected to the pad to be connected to an external conductor to receive signals and generate current to drive the diaphragm to vibrate to produce sound. Therefore, the voice coil must be connected to the pad with lead wires on both sides, and this lead wire is only used for electrical conduction, which will not only generate additional resistance, but also cause collisions in vibration and noise. [0003] The noise of the receiver module is mainly generated by the collision between the voice coil lead wire and the diaphragm or casing. In order to reduce collision with the diaphragm or housing, it is necessary to improve the control of the in-line trajectory of the lead wire and provide...
