Description

Technical Field

[0001] The utility model relates to a speaker module. Background Art

[0002] For a speaker module (hereinafter referred to as a module), due to the diverse functions of terminal electronic devices, various electronic modules are correspondingly increased, so that the space reserved for the module on the whole machine side is getting smaller and smaller, and miniaturization is the development trend. However, to meet the corresponding acoustic performance of the module, the module must have a corresponding cavity volume support. The smaller the module, the smaller the cavity volume and the higher the F0, which cannot meet the module performance requirements.

[0003] Existing technical solutions: Filling BASS powder can directly reduce the F0 of the module, which is an effective method to solve the insufficient cavity volume after the current module is miniaturized.

[0004] However, the existing technical solutions have the following disadvantages: After the BASS powder is filled into the module, it is required not to enter the inner core sound holes in the module, otherwise it will cause poor performance. Therefore, the inner core sound holes in the module must be isolated from the cavity filled with BASS powder; In order to prevent the BASS powder from entering the inner core sound holes and affecting the acoustic performance, the current common method is to cover a three-dimensional steel mesh or a mesh on the inner core. The three-dimensional steel mesh or the mesh separates the inner core of the module from the space filled with BASS powder. The three-dimensional steel mesh or the mesh is fixed on the module by glue. The added three-dimensional steel mesh or mesh makes it difficult to load automatically and affects the assembly efficiency; And additional glue fixation is required, which will make the product process complicated and the product yield will also decrease accordingly.
