[Brief description of the drawings]

[0018] In order to more clearly describe the technical solutions in the embodiments of the present invention, the following briefly introduces the necessary drawings used in the description of the embodiments. Obviously, the drawings described below are only some embodiments of the present invention, and those skilled in the art can further obtain other drawings based on these drawings without any creative work. [Figure 1] 1 is a schematic diagram showing a three-dimensional structure of a speaker box according to the present invention; [Diagram 2] 2 is an exploded schematic view showing the three-dimensional structure of the speaker box shown in FIG. [Diagram 3] FIG. 2 is a cross-sectional view taken along line A-A in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] The technical solutions in the embodiments of the present invention will be described below clearly and completely with reference to the drawings in the embodiments of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained based on the embodiments of the present invention without creative labor by those skilled in the art in the field of the present invention are all within the protection scope of the present invention.

[0020] As shown in Figures 1 to 3, the present invention provides a speaker box 100, which includes a housing 10, a speaker unit 20 accommodated in the housing 10, and a ventilation isolation member 30, which surrounds the housing 10 and forms an accommodation space 102 filled with sound-absorbing powder.

[0021] The housing 10 is rectangular and includes a bottom wall 121 away from the speaker unit 20 and a side wall 122 that is bent and extends from the bottom wall 121 toward the speaker unit 20, and the ventilation isolation member 30 is surrounded by the bottom wall 121 and the side wall 122 to form an accommodating space 102 filled with sound absorbing powder. A plurality of bosses 120 are provided on an inner surface 1220 of the side wall 122 and are spaced apart from each other to support the ventilation isolation member 30, and the ventilation isolation member 30 is fixedly connected to the bosses 120. In this embodiment, the bosses 120 are fixed to the ventilation isolation member 30 by an adhesive, thereby fixing the ventilation isolation member 30 to the housing 10. Compared with the prior art in which an adhesive is applied all around the ventilation isolation member to fix it to the housing, the ventilation isolation member 30 of the present invention only requires that an adhesive be applied locally to the connection point with the boss 120 to seal it, thereby saving space and making the ventilation isolation member 30 stronger and more stable in structure.

[0022] Specifically, the inner surface 1220 of the side wall 122 includes a first inner surface 1221 located at the long axis end and a second inner surface 1222 located at the short axis end, and four bosses 120 are provided, the four bosses 120 are provided on two opposing second inner surfaces 1222, and two bosses 120 are provided on each side of the second inner surface 1222. In other embodiments, the number of bosses does not need to be four as long as they can serve to fix the ventilation isolation member.

[0023] In this embodiment, the boss 120 is recessed from the outer surface of the side wall 122 of the housing 10 toward the inner surface, i.e., the boss 120 is integrally formed with the side wall 122 of the housing 10, and in other embodiments, the boss may be a separate member fixed to the inner surface of the housing. The boss 120 is located on the side of the ventilation isolation member 30 that is away from the speaker unit 20. Specifically, the ventilation isolation member 30 has a flat plate-like structure and includes a main body portion 31 and a fixing portion 32 that extends from the outer periphery of the main body portion 31 in a direction away from the speaker unit 20, and the fixing portion 32 has a continuous annular structure and abuts against the boss 120. The installation of the fixing portion 32 makes it easier for the boss 120 to be assembled and fixed to the ventilation isolation member 30, and in this embodiment, the ventilation isolation member 30 is fixed to the boss 120 by an adhesive at a position of the fixing portion 32 that corresponds to the boss 120.

[0024] The housing 10 further includes an upper housing 11 and a lower housing 12 which are connected to each other as covers, the speaker unit 20 is fixed to the upper housing 11, and the ventilation isolation member 30 is fixed to the lower housing 12. The upper housing 11 and the lower housing 12 are fixedly connected by an adhesive 40. The speaker box 100 further includes a circuit board 50 which supplies power to the speaker unit 20, and the circuit board 50 is fixed to the upper housing 11.

[0025] Compared with the prior art, the ventilation isolation member 30 provided by the present invention has a flat plate structure, and is fixed and supported by bosses 120 fixed to the inner surface 1220 of the side wall 122 of the housing 10, and a plurality of bosses 120 are installed at intervals. In this way, the ventilation isolation member 30 only needs to be sealed with the bosses 120 by adhesive, which saves space, improves the filling amount of the sound absorbing powder, and makes the ventilation isolation member 30 stronger and more stable in structure.

[0026] The above are only the embodiments of the present invention, and what should be pointed out here can be further improved by those skilled in the art without departing from the creative concept of the present invention, all of which belong to the protection scope of the present invention.
