【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.

Please refer to Fig. 1-3, wherein, Fig. 1 is the dimensional structure diagram of the utility model loudspeaker enclosure；Fig. 2 is this Another view stereo structure diagram of utility model loudspeaker enclosure；Fig. 3 is the part isometric structure decomposition figure of Fig. 1.

The utility model provides a kind of loudspeaker enclosure 100, including upper cover 1, lower cover 2, sounding monomer 3, FPC 4 and at the same time Connect the seal (not shown) of upper cover, lower cover and FPC.

The upper cover 1 is equipped with and is connected to the one of the lower cover 2 by it and is laterally away from the concave recessing groove in 2 direction of lower cover 11 and the filling slot 12 that is formed by 1 side-facing depressions of upper cover.The recessing groove 11 and 12 face of filling slot set and The filling slot 12 is located at the side of the remote lower cover 2 of the recessing groove 11.

The lower cover 2 is equipped with the upper surface 21 for accepting the FPC 4, the lower surface 22 opposite with the upper surface 21 and passes through Wear the filling hole 23 that the lower cover 2 is set.The position that the filling hole 23 corresponds to the recessing groove 11 is set.

The upper cover 1 surrounds receiving space 10 jointly with the lower cover 2.

The sounding monomer 3 is fixed on the upper cover 1 and is contained in the receiving space 10, the sounding monomer 3 with The upper cover surrounds ante-chamber (non-label), and the sounding monomer 3 surrounds back cavity with the lower cover 2 and the upper cover 1 and (do not mark jointly Number).Certainly, the sounding monomer 3 is also securable to the lower cover 2.

The receiving space 10 is separated into the ante-chamber and the back cavity by i.e. described sounding monomer 3.The ante-chamber is used for Sounding, the back cavity are used to improve frequency acoustic performance.

The FPC 4 is fixed on the lower cover 2, for example the upper surface 21 of the lower cover 2 is arranged on by double faced adhesive tape Formed and fixed.

Specifically, the FPC 4 is welded including the first weld part 41 in the receiving space 10, by described first The extension 42 and be located at the receiving space by what the extension 42 extended that portion 41 extends to outside the receiving space 10 The second weld part 43 outside 10.

First weld part 41 is used for the positive and negative electrode lead (not shown) for connecting the sounding monomer 3.

Second weld part 43 is used to connect with the positive and negative electrode of external power supply (not shown).

The extension 42 is through the recessing groove 11 by being extended in the receiving space 10 outside the receiving space 10.

The extension 42 exposes to the lower surface 22 of the lower cover 2 by the filling hole 23.Meanwhile the extension 42 also expose to the upper cover 1.

The seal is put by the filling hole 23 from the lower surface 22 of the lower cover 2 to the upper surface 21 Enter so that the upper cover 1, the extension 42 and the lower cover, which are formed, to be tightly connected.

Certainly, the seal is put also through the filling hole 23 from the upper surface 21 of the lower cover 2 to its lower surface 22 Enter.It is two-way to insert so that the sealing effect of the upper cover 1 and the lower cover 2 is more excellent.

In present embodiment, the seal selects silica gel, its mobility makes the two be easier to merge.Certainly, it is not limited to This.

In present embodiment, the seal inserts fusion by the filling hole 23, and formation is surrounded on the extension 42 Cushion rubber, the upper cover 1 and the lower cover 2 are formed into sealing, the position extended especially for the extension 42, i.e. institute State recessing groove 11 and form sealing, and then realize the sealing of the receiving space 10 of the loudspeaker enclosure 100.And the seal Through it is described filling hole 23 from the lower surface 22 of the lower cover 2 to the upper surface 21 insert when will not the FPC 4 with The binding face of the lower cover 2 produces offset step, and the sealing effect of formation is good.

In present embodiment, the filling slot 12 is set with filling 23 face of hole.The structure causes the seal It can be more convenient to insert.

In present embodiment, the width in the filling hole 23 is set to be more than the width of the extension 42, the filling slot 12 Width be also configured as width more than the extension 42.The setting of the structure make it that the seal is easier to insert and close It is more preferable to seal effect.

It should be noted that so-called width, in the present embodiment, refers to the extension perpendicular to the extension 42 The direction in direction.

In present embodiment, because the FPC 4 is arranged on the lower cover 2, then actually described recessing groove 11 and the back cavity 102 connections, that is to say, that also the back cavity forms sealing even if seal fusion makes the recessing groove 11 form sealing.

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.
