Technical field

Acoustics component is the utility model is related to, more specifically, the utility model is related to loudspeaker module upper case structure, raising Sound device module and acoustic element.

Background technology

At present, in loudspeaker module, steel disc is molded with upper shell.When using loudspeaker, steel disc can be by certain Pressure, for a long time with the deformation of housing, recessed phenomenon occurs in steel disc, at leisure can state in a concave shape.Such that The distance of steel disc and vibrating diaphragm dome reduces, and so as to cause the ante-chamber of loudspeaker module to diminish, oscillation space reduces on vibrating diaphragm, and then Influence the acoustical behavior of loudspeaker module.

Utility model content

A purpose of the present utility model, which is to maintain on vibrating diaphragm, shakes space invariance, ensure that the good sound of loudspeaker module Learn performance.

According to one side of the present utility model, there is provided a kind of loudspeaker module upper case structure, including upper shell and inserts, The inserts is embedded to be arranged in the upper shell, and with the upper shell integrated injection molding, the inserts and loudspeaker The position of vibrating diaphragm in module is corresponding, and the inserts is provided with the lug boss gradually to be raised up from periphery to center, The protrusion direction of the lug boss is set along away from the direction of the vibrating diaphragm.

Preferably, a lateral edges of the inserts are provided with acclivitous first joint portion, the side of the inserts opposite side Edge is provided with the second joint portion tilted down, and first joint portion and second joint portion are embedded in the upper shell.

Preferably, the inserts is as made by metal material.

Preferably, the inserts is steel disc.

According to second aspect of the present utility model, there is provided a kind of loudspeaker module, including above-mentioned upper case structure, and The lower shell structure being fixed together with the upper case structure.

According to second aspect of the present utility model, there is provided a kind of acoustic element, including above-mentioned loudspeaker module.

One of the present utility model has technical effect that inserts is centrally formed lug boss, is under pressure deformation in inserts When, being maintained to the distance between vibrating diaphragm and inserts will not reduce, and keep on vibrating diaphragm that oscillation space is constant, ensure that and raise one's voice The good acoustic performance of device module.In addition, loudspeaker module upper casing of the present utility model, its inserts is that gradual change is convex, outward appearance Estimate as plane, without any impression, do not influence the overall appearance of product.

It is of the present utility model other by referring to the drawings to the detailed description of exemplary embodiment of the present utility model Feature and its advantage will be made apparent from.

Brief description of the drawings

The accompanying drawing of a part for constitution instruction describes embodiment of the present utility model, and uses together with the description In explanation principle of the present utility model.

Fig. 1 is the schematic diagram of loudspeaker module upper case structure of the present utility model.

Fig. 2 is that schematic diagram is cutd open in the side of loudspeaker module upper case structure of the present utility model.

Embodiment

Various exemplary embodiments of the present utility model are described in detail now with reference to accompanying drawing.It should be noted that：It is unless another Illustrate outside, the part and the positioned opposite of step, numerical expression and numerical value otherwise illustrated in these embodiments is unlimited The scope of the utility model processed.

The description only actually at least one exemplary embodiment is illustrative to be never used as to this practicality below New and its application or any restrictions used.

It may be not discussed in detail for technology and equipment known to person of ordinary skill in the relevant, but in appropriate situation Under, the technology and equipment should be considered as part for specification.

In shown here and discussion all examples, any occurrence should be construed as merely exemplary, without It is as limitation.Therefore, other examples of exemplary embodiment can have different values.

It should be noted that：Similar label and letter represents similar terms in following accompanying drawing, therefore, once a certain Xiang Yi It is defined, then it need not be further discussed in subsequent accompanying drawing in individual accompanying drawing.

It refer to shown in Fig. 1 and Fig. 2, loudspeaker module upper case structure of the present utility model, including upper shell 1 and inserts 2. Inserts 2 is embedded to be arranged in upper shell 1, and with the integrated injection molding of upper shell 1, using integrated injection molding, be simple to manufacture, reduce The step of inserts 2 assembles with upper shell 1, the time of the manufacturing is saved, improve the efficiency of the manufacturing.Inserts 2 with The position of vibrating diaphragm 3 in loudspeaker module is corresponding, is shaken in the oscillation space 4 that vibrating diaphragm 3 can be formed at it between inserts 2 It is dynamic.Inserts 2 is provided with and is gradually raised up from periphery to center and form lug boss 21, and the protrusion direction edge of lug boss 21 deviates from The direction of vibrating diaphragm is set.The setting of lug boss 21 can cause oscillation space 4 under most initial state, i.e. inserts 2 is in non-stress State, raise up a part.The space that this part in oscillation space 4 raises up, retaining space can be used as, embedding , can be downwardly concave sunken in this retaining space when part 2 is deformed by external force effect, so as to ensure that the oscillation space of vibrating diaphragm 4 is constant, and then ensure that the good acoustic performance of loudspeaker module.

Preferably, a lateral edges of inserts 2 are provided with acclivitous first joint portion 22, and the edge of the opposite side of inserts 2 is set There is the second joint portion 23 tilted down, and the first joint portion 22 and the second joint portion 23 are moulded in upper shell 1.Pass through Inserts 2 is moulded in upper shell 1 by one joint portion 22 and the second joint portion 23, forms a kind of internal grasp so that injection jail Lean on；Moreover, the incline direction of the first joint portion 22 and the second joint portion 23 is on the contrary, branch can be provided to inserts 2 in both direction Support force, it ensure that the stability that inserts 2 is connected with upper shell 1.

It refer to shown in Fig. 1 and Fig. 2, inserts 2 as made by metal material, be easy to process and mould, and is easy to by metal material Process by four circumferential center flexible transition and raise up and form lug boss 21.Preferably, inserts 2 is steel disc, material into This is low, is readily available, reduces the cost of the manufacturing.

Loudspeaker module of the present utility model, including above-mentioned upper shell structure, and be fixed together with upper case structure Lower shell structure.By setting above-mentioned upper shell structure, the good acoustic performance of loudspeaker module can be ensure that.Certainly, In the specific implementation, loudspeaker module can also set shell in module simultaneously, now, in module upper casing, module under shell and module Shell assembles together jointly, forms a cavity that can accommodate loudspeaker monomer.

Acoustic element of the present utility model, including above-mentioned loudspeaker module.Include above-mentioned upper shell knot by setting The loudspeaker module of structure, the good acoustic performance of acoustic element can be ensure that.

Although some specific embodiments of the present utility model are described in detail by example, this area It is to be understood by the skilled artisans that above example merely to illustrate, rather than in order to limit the scope of the utility model.This Field it is to be understood by the skilled artisans that can not depart from the scope of the utility model and spirit in the case of, to above example Modify.The scope of the utility model is defined by the following claims.
