The description only actually at least one exemplary embodiment is illustrative below, never as to this practicality
New and its application or any limitation for using.
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 a part for specification.
In all examples shown here and discussion, 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 in individual accompanying drawing, then it need not be further discussed in subsequent accompanying drawing.
The utility model provides a kind of loudspeaker module, the housing injection casing and and metallic plate of the loudspeaker module.
The utility model connects stiffened region by being formed on a metal plate, so as to improve the combination between metallic plate and injection casing
Power, reduces the possibility that gap is produced between metallic plate and injection casing.It is possible to further improve the acoustics of loudspeaker module
Performance.
Fig. 1 shows the structure of the metallic plate 12 provided in a kind of implementation method of the utility model, the part of metallic plate 12
Region can be attached to the combination reliability on metallic plate 12, this reality for raising injection casing 11 with the directly contact of injection casing 11
Stiffened region 121 is connected with new being provided with the region on the basis of injection casing 11 on metallic plate 12.The connection stiffened region 121
Injection casing 11 can be molded into by the combination power between several forms raising injection casing 11 and metallic plate 12
The surface of the metallic plate 12 is closely attached to during type, the possibility for producing gap is reduced.
The side, sectional structure that Fig. 2,3 show the loudspeaker module that the utility model is provided, loudspeaker module includes
Module casing and loudspeaker assembly 2, have accommodating chamber in the module casing, the loudspeaker assembly 2 is arranged on the receiving
In chamber.The loudspeaker assembly 2 can include vibration component, magnetic circuit component and other portions for producing sound of loudspeaker
Part.The module casing then includes injection casing 11 and metallic plate 12, and the injection of the metallic plate 12 is fixed on the injection casing
In 11.The subregion of metallic plate 12 or part surface are directly contacted with the injection casing 11, the connection stiffened region 121
In the part contacted with injection casing 11 on metallic plate 12.
Specific constructive form of the utility model not to the connection stiffened region is limited, at least following several tools
Body structure can realize the functional effect of the connection stiffened region, the utility model explanation in herein below.
In one embodiment, the surface of the connection stiffened region 121 can be rough, rough table
Face increased the surface area of connection stiffened region 121, also cause that the surface of connection stiffened region 121 is prolonged in part to different directions
Stretch.So, when the injection molding material of injection casing 11 is moulded on the metallic plate 12, both combination areas are bigger, and
And combination power is towards different directions.When the trend that there is disengaging, generation gap between injection casing 11 and metallic plate 12
When, larger overall combination power, and the combination power in opposite direction with disengaging trend can be prevented between the two
Produce gap.
Alternatively, rough surface can be made with stamped moulding process on connection stiffened region, can in stamping mold
So that with raised and depression dot matrix, so, punching press effect can form rough structure, i.e. shape on connection stiffened region
Into the connection stiffened region.Alternatively, rough surface can be in the concavo-convex array of uniform round dot on connection stiffened region
Form, the concave-convex surface region of this form is uniformly distributed, and is not likely to produce structural defect, it is easy to obtain by Sheet Metal Forming Technology
Arrive.
Alternatively, except processing outer by punch forming process, can also be formed by way of strong acid corrosion it is concavo-convex not
Flat connection stiffened region surface.For example, pickling corruption first can be carried out to the surface for connecting stiffened region using strong acid such as sulfuric acid, hydrochloric acid
Erosion, produces rough corrosion surface, and surface is cleaned with weak base and clear water successively again afterwards, washes corrosive liquid.
It is this by corrode produce rough surface, with more complicated, irregular concaveconvex structure, can for injection casing with
Good conjugation condition is provided between metallic plate.
In another embodiment, the connection stiffened region can be have good combination active force with injection casing
Coating.In order to ensure the structural reliability of metallic plate, metallic plate is generally made of materials such as steel or aluminium alloys, but these materials
Combination power between material and injection casing is relatively poor, so, one layer of coating can be formed on the connection stiffened region,
The material of coating uses the material and injection casing between with good combination active force.For example, alternatively, the coating can be with
It is nickel zinc coating, this kind of material has relatively porous microstructure, in injection moulding, the injection molding material of injection casing can one
The infiltration coating of degree is determined, so that the combination power significantly between reinforcing injection casing and the metallic plate.This practicality
New to be not intended to limit the coating can only be nickel zinc coating, can also form coating using other materials.
In another embodiment, the connection stiffened region can also be bonding layer, and the bonding layer is in injection molding
Certain bonding effect can be produced to injection molding material, during shell so that the combination improved between the injection casing of formation and metallic plate is made
Firmly.
In addition, the overlapping region in order to reduce injection casing and metallic plate as far as possible, the thickness overall to reduce loudspeaker module
Degree, alternatively, the metallic plate only has fringe region and is contacted with the injection casing, the zone line of metallic plate not with the note
Modeling shell contact.Correspondingly, as shown in figure 1, the connection stiffened region 121 also is located at the fringe region of the metallic plate 12.It is special
Not, in some embodiments, require that the edge of the metallic plate 12 can to meet the overall structure of loudspeaker module
So that with bending edge, these bending edges generally require to be embedded into the injection casing 11.So, the connection stiffened region 121
Extend on the bending edge.Especially, on the bending edge, connection reinforcing is can be formed with two surface
Area, the utility model is limited not to this.
Although being described in detail to some specific embodiments of the present utility model by example, this area
It is to be understood by the skilled artisans that above example is merely to illustrate, rather than in order to limit scope of the present utility model.This
Field it is to be understood by the skilled artisans that can be in the case where scope and spirit of the present utility model not be departed from, to above example
Modify.Scope of the present utility model is defined by the following claims.
