Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 12, the present invention provides a sound box, which is applied to a display and assembled with a housing 100 of the display (as shown in fig. 12); as shown in fig. 1-3, the sound box includes an extension portion 1, and a sound box assembly 2 and a bracket 3 arranged in parallel; the extension part 1 is arranged on the bracket 3 and is positioned on one side of the bracket 3 close to the sound box assembly 2; specifically, one end of the extension part 1 is connected with the bracket 3, and the other end of the extension part extends towards the sound box assembly 2; according to the invention, the extension part 1 is detachably connected with the sound box component 2, and the support 3 is installed and detached on the sound box component 2 through the installation and the detachment of the extension part 1 and the sound box component 2.

Further, the loudspeaker box further comprises a binding mesh 4, the binding mesh 4 is provided with an opening, the binding mesh 4 is provided with a drawstring passage 5 along the circumferential direction of the opening, a drawstring 6 is arranged in the drawstring passage 5, and when the drawstring 6 is drawn tightly, as shown in fig. 10, the binding mesh 4 slides and contracts along the drawstring 6, so that the opening of the binding mesh 4 is reduced, and the function of containing articles by the binding mesh 4 is realized. In the present invention, the drawstring passage 5 is directed toward the side of the support 3 where the extension portion 1 is disposed, then the binding mesh 4 is sleeved on the support 3, and then the drawstring 6 is tightened to reduce the opening of the binding mesh 4, so that the support 3 can be accommodated in the binding mesh 4, as shown in fig. 9, the binding mesh 4 is fixed to the support 3 by tightening the drawstring 6.

After the extension part 1 is detached from the sound box assembly 2, the drawstring 6 is loosened to enlarge the opening of the binding net cloth 4, so that the binding net cloth 4 can be separated from the support 3, and the binding net cloth 4 is replaced or cleaned.

According to the invention, the binding net cloth 4 is mounted or dismounted on the support 3 through the tightening or loosening of the drawstring 6, the binding net cloth 4 does not need to be glued, and the binding net cloth 4 and the support 3 cannot be damaged when the binding net cloth 4 is dismounted.

Preferably, as shown in fig. 9, when the drawstring 6 is drawn tight, the end of the extension portion 1 not connected to the bracket 3 can pass through the opening of the binding mesh 4, so as to be detachably connected to the sound box assembly 2; when the drawstring 6 is drawn tightly, the fold volume at the opening of the binding mesh 4 does not interfere the connection between the extension part 1 and the sound box component 2.

As shown in fig. 7, the bunched port mesh 4 includes a mesh body 41 and a folded portion 42, the folded portion 42 is disposed around the mesh body 41 in a circumferential direction, the folded portion 42 is located on one side of the mesh body 41, an inner side of the folded portion 42 is connected to the mesh body 41, and an outer side of the folded portion 42 is also connected to the mesh body 41, so that the folded portion 42 and the mesh body 41 form the drawstring passage 5, and an accommodating space is provided for the drawstring 6 through the drawstring passage 5.

Further, in order to facilitate the user to adjust the opening size of the bunched mesh 4 by tightening or loosening the drawstring 6, the drawstring 6 can only be partially positioned in the drawstring passage 5, and the other part is positioned outside the drawstring passage 5, so that the user can hold the drawstring 6 outside the drawstring passage 5. In a preferred embodiment, two through holes are arranged at intervals on the side wall of the drawstring channel 5, and the through holes are communicated with the drawstring channel 5, one end of the drawstring 6 passes through one through hole into the drawstring channel 5 and then passes through the other through hole, namely, two free ends of the drawstring 6 are positioned outside the drawstring channel 5. The distance between the two through holes is small, so that after the drawstring 6 penetrates into the drawstring passage 5 from one through hole, the drawstring 6 can surround the drawstring passage 5 for a length greater than a half of the length of the drawstring passage and then penetrates out from the other through hole, so as to ensure that when the drawstring 6 is drawn tightly through the two free ends of the drawstring 6, the opening reduction amount of the bunching mesh 4 is large, the opening area of the bunching mesh 4 is smaller than the area of the bracket 3 facing the loudspeaker box assembly 2, and ensure that the bracket 3 cannot be separated from the opening of the bunching mesh 4.

As shown in fig. 2, 8 and 9, the bracket 3 is provided with a plurality of positioning pins 7, the positioning pins 7 and the extension portion 1 are both located on the same side of the bracket 3, the plurality of positioning pins 7 are sequentially arranged along the circumferential direction of the bracket 3, and when the binding opening of the binding opening mesh cloth 4 on the bracket 3 is in a binding opening state (the drawstring 6 is pulled tightly), the area where the positioning pins 7 are located overlaps with the shielding area of the binding opening mesh cloth 4 on the bracket 3. The folding part 42 and the mesh cloth body 41 are made of the same material and are elastic mesh cloth, when the drawstring 6 is tightly pulled, the folding part 42 and the mesh cloth body 41 which are overlapped are sleeved with the positioning pin 7, so that the positioning pin 7 sequentially penetrates through the mesh cloth body 41 and the folding part 42, the mesh cloth body 41 and the folding part 42 are positioned synchronously, and the opening binding mesh cloth 4 after binding is prevented from slipping on the support 3. Because the folded part 42 and the mesh body 41 are both elastic meshes, even if the mesh body 41, the folded part 42 and the positioning pin 7 are sleeved and disassembled for many times, the mesh body 41 and the folded part 42 can also recover elastic deformation as soon as possible, and the structure of the mesh body 41 and the folded part 42 cannot be greatly influenced.

As shown in fig. 11, the support 3 has a plurality of sound emitting holes 8, and the sound emitting holes 8 penetrate through the support 3 along the thickness direction of the support 3; in a first preferred embodiment, as shown in fig. 1, the support 3 is covered by the tying mesh 4, and the sound outlet hole 8 is protected by the tying mesh 4, so as to reduce dust or foreign matter from gathering in the sound outlet hole 8.
