Abstract
The utility model discloses a kind of loudspeaker module shell and the attachment structure of steel disc, including module upper casing and steel disc, upper casing brace rod is provided with the outside of module upper casing, the surface that steel disc coordinates with upper casing brace rod is pulled up forming boss, and boss is overlapped on upper casing brace rod and is bonded together by gluing.The utility model has following technique effect using above-mentioned technical proposal：The adhesion strength of gluing between steel disc and module upper casing can be increased；Do not influence acoustical behavior simultaneously.
Description
Technical field
The utility model is related to technical field of electronic products, more particularly to a kind of loudspeaker module shell and steel disc
Attachment structure.
Background technology
With light, the thin development trend of mobile phone, the requirement to loudspeaker module thickness is also more and more thinner, in order to reach more
Acoustical behavior high and monomer can smoothly be loaded module, it is common in the industry at present to do while limited by module short transverse
Method is injection molding steel disc mode, and some module shell structures can not meet injection molding steel disc technique, can only take painting glue sticking steel disc knot
Structure mode, module is spoken for side.
As shown in Figure 1 and Figure 2, the attachment structure of a kind of existing module shell and steel disc, on module
There is acoustic aperture 3, one end that module upper casing 5 is located at out the side of acoustic aperture 3 is hanging, steel disc 1 between shell 5 and module lower casing 6
Hanging near the position for going out the side of acoustic aperture 3, steel disc 1 is weak with the gluing adhesive strength of module shell 2, reduces module intensity.
As shown in figure 3, existing another module shell and the attachment structure of steel disc, reinforcement is set in the outside of module upper casing 5
Support bar 4, strengthens support bar 4 and is arranged on out outside acoustic aperture 3, and position of the steel disc 1 on the inside of acoustic aperture is by strengthening brace rod 4
Support, is bonded on module shell 2, it is necessary to reduce the height of acoustic aperture to ensure that the outside of steel disc 1 is smooth, makes reinforcement brace rod 4
Upper surface is smooth with steel disc 1 to fit, and this mode can solve the adhesion strength of steel disc 4 and the gluing of module upper casing 5, but reduce
Acoustical behavior.
Utility model content
The technical problems to be solved in the utility model is directed to the deficiencies in the prior art and provides a kind of loudspeaker module
The attachment structure of shell and steel disc, the structure can increase the adhesion strength of gluing between steel disc and module upper casing, together
When do not influence acoustical behavior.
Following technical scheme is used to solve above-mentioned technical problem the utility model：A kind of loudspeaker module shell and steel disc
Attachment structure, including module upper casing and steel disc be provided with upper casing brace rod on the outside of module upper casing, steel disc is matched somebody with somebody with upper casing brace rod
The surface of conjunction is pulled up forming boss, and boss is overlapped on upper casing brace rod and is bonded together by gluing.
The utility model has following technique effect using above-mentioned technical proposal：Can increase applied between steel disc and module upper casing
The adhesion strength of glue；Do not influence acoustical behavior simultaneously.
Above-mentioned technical proposal is described further with reference to the accompanying drawings and examples：
Brief description of the drawings：
Structural representation when accompanying drawing 1 is the connection of module shell and steel disc in background technology；
Sectional view when accompanying drawing 2 is the connection of one of which module shell and steel disc in background technology；
Sectional view when accompanying drawing 3 is the connection of another assembly housing and steel disc in background technology；
Accompanying drawing 4 is the structural representation of steel disc in the utility model；

Specific embodiment
Embodiment, as Figure 4-Figure 6, the attachment structure of a kind of loudspeaker module shell and steel disc, including module upper casing 5 and
Steel disc 1, the outside of module upper casing 5 is provided with upper casing brace rod 7, and the surface that steel disc 1 coordinates with upper casing brace rod 7 is pulled up being formed
There is boss 8, boss 8 is overlapped on upper casing brace rod 7 and is bonded together by gluing.Steel can both be ensured using this structure
Piece 1 is smooth to be fitted on module shell 2, while not influenceing acoustical behavior.
Upper casing brace rod 7 is going out the outside of acoustic aperture 3, steel disc boss 8 and the cooperation gluing mode of upper casing brace rod 2, this structure
Without reducing out the height of acoustic aperture 3, while increased the adhesion strength of steel disc 1 and the gluing of module upper casing 5, and acoustics is not influenceed
Performance.
