Preferably, the extension is included towards the upper surface of the upper cover and the lower surface towards the lower cover, institute State encapsulated holes and run through the upper surface and the lower surface, the liquid sealant is coated on the upper surface and by the envelope Dress hole spills over the lower surface from the upper surface, is tightly connected the lower surface of the extension and the lower cover.

Preferably, the shape of the encapsulated holes is at least one of circular, ellipse or polygon.

The beneficial effects of the utility model：

The loudspeaker enclosure of the utility model, when being assembled, can be towards on described in the front of circuit board The one side of lid, coats above-mentioned seal, due to being provided with the encapsulated holes on the extension of circuit board, seal energy The back side of extension, that is, the surface that circuit board is contacted with the lower cover are enough spilt over by the encapsulated holes, it is thus possible in electricity The front and back of road plate is covered with the seal, can make it that sealing effect is good, avoids the loudspeaker enclosure gas leakage Risk, and then improve the acoustical behavior of the loudspeaker enclosure.

【Brief description of the drawings】

It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the utility model Example is applied, for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Other attached drawings are obtained, wherein：

Fig. 1 is the stereochemical structure exploded view of the utility model loudspeaker enclosure；

Fig. 2 is the stereochemical structure exploded view at another visual angle of the utility model loudspeaker enclosure；

Fig. 3 is the dimensional structure diagram of the utility model loudspeaker enclosure；

Fig. 4 is the structure diagram of the circuit board in the utility model loudspeaker enclosure.

【Embodiment】

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the part of the embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work The all other embodiment obtained, shall fall within the protection scope of the present invention.

As shown in Figures 1 to 4, the utility model provides a kind of loudspeaker enclosure 100.The loudspeaker enclosure 100 includes upper cover 110th, the lower cover 120 of receiving space 111, the sounding list being contained in the receiving space 111 are surrounded jointly with the upper cover 110 Body 130 and the electrical connection sounding monomer 130 and the circuit board 140 being located between the upper cover 110 and the lower cover 120.

Wherein, the circuit board 140 includes the connecting portion 141 being located in the receiving space 111 and by the connecting portion 141 extend to the extension 142 outside the receiving space 111.The circuit board 140 is preferably flexible PCB.

Wherein, the encapsulated holes of its thickness are provided through on the extension 142 close to the position of the connecting portion 141 142a。

The loudspeaker enclosure 100 further includes seal (not showed that in figure), and the seal can pass through the encapsulation The direction of hole 142a towards the lower cover 120 is inserted, to be tightly connected the extension 142 and the lower cover 120.

When assembling the loudspeaker enclosure 100 of the structure, the upper cover can be towards in the front of circuit board 140 110 surface, coats above-mentioned seal, due to being provided with the encapsulated holes 142a on the extension 142 of circuit board 140, because This, seal can reach the back side of extension 142, that is, circuit board 140 and the lower cover 120 by encapsulated holes 142a The surface of contact, it is thus possible to which the front and back in circuit board 140 is covered with the seal, and then can cause sealing to imitate Fruit is good, improves the acoustical behavior of the loudspeaker enclosure 100.

Further, since only in the above-mentioned seal of the front surface coated of circuit board 140, it is not necessary to single again on lower cover 120 Filling hole is solely opened up, to insert above-mentioned seal from filling hole, therefore, the loudspeaker enclosure 100 of the structure can also simplify making Technique, reduces cost of manufacture.

It should be noted that the concrete shape of encapsulated holes 142a and specific size for being formed on extension 142 Do not define, for example, the shape of encapsulated holes 142a can be circular, ellipse or polygon, certainly, the encapsulated holes 142a can also its other regular figure or irregular figure, certainly, in order to from simplify manufacture craft from the point of view of, the encapsulation Hole 142a is preferably by circle.As for the size of encapsulated holes 142a, it can be set according to actual needs, not limited herein It is fixed.

Explanation is needed further exist for, is not defined for the specific species of seal, the seal is preferably Liquid sealant can be used.In this way, seal can be caused to reach circuit board 140 better by above-mentioned encapsulated holes 142a The back side and lower cover 120 upper surface, realize sealing.

As shown in Figure 1 and Figure 4, the extension 142 is included towards the upper surface 142b of the upper cover 110 and towards institute The lower surface 142c of lower cover 120 is stated, the encapsulated holes 142a runs through the upper surface 142b and lower surface 142c, the liquid State seal spills over the following table of the extension 142 by the upper surface 142b of the encapsulated holes 142a from the extension 142 Face 142c, to be tightly connected the lower surface 142c of the extension 142 and the lower cover 120.

It should be appreciated that above-mentioned loudspeaker enclosure 100 can be applied to the electronic products such as mobile phone, tablet, notebook In.

Above-described is only the embodiment of the utility model, it should be noted here that the ordinary skill for this area For personnel, on the premise of not departing from the utility model and creating design, improvement can also be made, but these belong to this practicality New protection domain.
