【Embodiment】

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.

Fig. 1 is please referred to Fig. 4, wherein, Fig. 1 is the stereochemical structure decomposing schematic representation of the utility model loudspeaker enclosure； Fig. 2 is the structural representation after loudspeaker enclosure shown in Fig. 1 is assembled, and Fig. 3 is the cross-sectional view along line A-A shown in Fig. 2, figure 4 be part A enlarged drawing shown in Fig. 3.The loudspeaker enclosure 100 includes the housing 1 with receiving space and is contained in the collecting Loudspeaker monomer 5 in space.

The housing 1 includes upper lid 11 and the upper lid 11 cooperatively forms the lower cover 13 of the receiving space.

The loudspeaker monomer 5 include frame 51, be fixedly arranged in the frame 51 and for vibrate occur vibrating diaphragm 53 with And through the leak holes 55 of the frame 51.

The frame 51 includes with the vibrating diaphragm 53 is affixed upper surface 511 and the following table relative with the upper surface 511 Face 513.

After the receiving space to be separated into the ante-chamber 7 that is in communication with the outside and be relative with the ante-chamber 7 for the vibrating diaphragm 53 Chamber 8.

The leak holes 55 run through the upper surface 511 with the lower surface 513 to connect the ante-chamber 7 and the back cavity 8.In the present embodiment, the quantity of the leak holes 55 is two, and leak holes 55 described in two are respectively positioned at the vibrating diaphragm 53 Two opposite ends, but the quantity of the leak holes 55 is not limited to two.It is appreciated that in other embodiments, it is described to let out Dew hole 55 is not limited to above-mentioned set-up mode, for example, the leak holes 55 can be arranged to sequentially pass through the vibrating diaphragm 53, The leak holes 55 can also be disposed through the vibrating diaphragm 53 by the upper surface 511 and the lower surface 513.By institute State leak holes 55 and connect the ante-chamber 7 and the back cavity 8, leak holes 55 destroy ante-chamber 7 and closed, destroy the resonant bars of ante-chamber 7 Part, reduces the resonance of ante-chamber 7, reduces distortion, and leak holes 55 can also balance the air pressure inside loudspeaker enclosure 100.

In order to prevent dust or current from entering the inside of the loudspeaker monomer 5, the loudspeaker enclosure 100 also includes setting In in the frame 51 and covering the breathable barriers 9 of the leak holes 55.The breathable barrier 9 is made up of waterproof material, For example, PET net film.
