Specific embodiment

To describe various exemplary embodiment of the present utility model now with reference to accompanying drawing in detail.It should be noted that：Unless it is another Illustrate outward, the positioned opposite, numerical expression of the part otherwise illustrating in these embodiments and step and numerical value do not limit Make scope of the present utility model.

Description only actually at least one exemplary embodiment is illustrative below, never as to this practicality Any restriction that is new and its applying or use.

May be not discussed in detail for technology and equipment known to person of ordinary skill in the relevant, but in suitable situation Under, described technology and equipment should be considered a part for specification.

In all examples with discussion shown here, any occurrence should be construed as merely exemplary, and not It is as restriction.Therefore, other examples of exemplary embodiment can have different values.

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

The utility model is in order to solve problems of the prior art, there is provided a kind of connection knot of loudspeaker monomer Structure, this structure can effectively improve injection shell fragment and resist the ability that mould pushes and leads to deformation, effectively prevent injection molding material and spill over The pad locations on injection shell fragment surface.

With reference to Fig. 1, Fig. 3, a kind of attachment structure of loudspeaker monomer that the utility model provides, it include housing 1 and It is moulded in the injection shell fragment 2 in housing 1.Wherein, described injection shell fragment 2 include exposing housing 1 upper surface the first extension 20, Expose the second extension 21 of housing 1 lower surface, and connect described first extension 20, the kink of the second extension 21 22.

Injection shell fragment 2 of the present utility model can be integrally formed, for example can be in injection shell fragment 2 by way of bending Upper formation the first extension 20, the second extension 21 and kink 22, the first extension 20 with the second extension 11 can be It is parallel to each other, under injection shell fragment 2 elastic reaction of itself, between leaving between the first extension 20 and the second extension 21 Gap 23 is so that this injection shell fragment 2 entirety is in C font.

Injection shell fragment 2 of the present utility model, the one of described first extension 20 free termination direction the second extension 21 Side blow is pressed with the arc-shaped lug boss 24 for contacting with the second extension 21 surface.Punching press is carried out to the first extension 20, The upper surface of the first extension 20 forms stamped groove, and forms the lug boss 24 of arc-shaped in its lower surface, this lug boss 24 with Second extension 21 contacts so that the free termination of the first extension 20 is supported on the second extension 21, thus Improve the first extension 20 and resist the ability deforming towards the second extension 21 leading to due to mould pressing；Corresponding Ground, also improves the ability deforming towards the first extension 20 that the second extension 21 is resisted mould pressing and led to.

This lug boss is naturally it can also arranged on the second extension 21, equally can achieve above-mentioned effect.For example described Lug boss is arranged on the side towards the first extension 20 for the free termination of described second extension 21.Second extension 21 can be entered Row punching press, forms stamped groove in the lower surface of the second extension 21, and end face forms the lug boss of arc-shaped, this lug boss thereon Contact with the first extension 20 so that the free termination of the first extension 20 is supported on the second extension 21, by This is improve the first extension 20 and resists the ability deforming towards the second extension 21 being led to due to mould pressing；Right Ying Di, also improves the ability deforming towards the first extension 20 that the second extension 21 is resisted mould pressing and led to.

Certainly, for a person skilled in the art, can also set respectively in the first extension 20, the second extension 21 Put an above-mentioned lug boss, here no longer illustrates.

Injection shell fragment 2 of the present utility model for example can be moulded in shell by inserts mode well-known to those skilled in the art In body 1.The position of described injection shell fragment 2 first extension 20, the edge of the second extension 21 and kink 22 for example can be made Injection within the case 1, realizes the combination of injection shell fragment 2 and housing 1.In order to improve the binding ability of injection shell fragment 2 and housing 1, At least one bending also can be arranged on described injection shell fragment 2 grabs glue portion 25, with reference to Fig. 4.After injection completes, described grab glue Portion 25 can stretch in housing 1 in a longitudinal direction, which thereby enhances the bond strength of injection shell fragment 2 and housing 1.

In one specific embodiment of the utility model, also include voice coil loudspeaker voice coil 3, after shoot piece 4, with reference to Fig. 1, Fig. 2, institute State the upper end that voice coil loudspeaker voice coil 3 can be arranged on housing 1 by mode well-known to those skilled in the art；Shoot piece 4 afterwards and be located at housing 1 Lower end, for example, can arrange mounting groove 10 in the lower surface of housing 1, the shape of this mounting groove 10 and size with after shoot the peace of piece 4 Dress face matches.Injection shell fragment 2, after shoot piece 4 and can be respectively arranged with two, be separately positioned on the two ends of housing 1, to ensure The stability of electrical connection between them.

Wherein, the solderable upper surface in injection shell fragment 2 first extension 20 of the lead of described voice coil loudspeaker voice coil 3 is it is achieved that voice coil loudspeaker voice coil 3 Electrical connection with injection shell fragment 2；Then shoot the lower surface that piece 4 can be directly welded at described injection shell fragment 2 second extension 21 Upper it is achieved that after shoot electrical connection and the mechanical connection of piece 4 and injection shell fragment 2.By this connected mode, can be by voice coil loudspeaker voice coil 3 By be molded shell fragment 2 with after shoot together with piece 4 turns on.

When being assembled, it is welded on shooting piece 4 after this on the circuit board of exterior terminal, thus by voice coil loudspeaker voice coil 3 Electric signal communication is to above exterior terminal.The lower surface shooting piece 4 after described is preferably provided with elastic deformation portion 40.Install When, pad corresponding with exterior terminal circuit board extruding in this elastic deformation portion 40 is combined together, and shoots piece 4 with after ensureing The stability electrically connecting with exterior terminal.

Attachment structure of the present utility model, in order to the electric signal of inside configuration is guided to structural outer, is provided with and has One extension, the injection shell fragment of the second extension, the first extension of this injection shell fragment exposes from the upper surface of housing, to be electrically connected Connect the lead of voice coil loudspeaker voice coil, the second extension exposes from the lower surface of housing, shoot piece with after electrically connecting；In the first extension and/or The free termination of the second extension is provided for contacting lug boss each other, is greatly improved the first extension by this lug boss Portion, the second extension opposing lead to the ability deforming because mould pushes, such that it is able to prevent injection molding material from spilling over injection shell fragment Surface it is ensured that pad locations and voice coil loudspeaker voice coil on injection shell fragment, after shoot the stability that piece is connected.

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 of without departing from scope and spirit of the present utility model, to above example Modify.Scope of the present utility model is defined by the following claims.
