[0025] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are given in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure content of the present utility model more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0028] Please refer to Figures 1 to 6 , which is a sound column modular housing structure according to an embodiment of the present utility model, including a rear shell 10 and a plurality of panel fittings 20 arrayed and installed on the front surface of the rear shell 10; the plurality of panel fittings 20 are spliced with each other to form a speaker panel, and the speaker panel is used for positioning and installing a speaker 30.

[0029] The rear shell 10 includes a rear shell base body 11 arranged in a substantially "n" shape, support parts 12 extending inward from the inner walls of opposite sides of the rear shell base body 11, and positioning parts 13 extending inward from the inner sides of the respective support parts 12; the positioning parts 13 are arranged in a substantially "n" shape. Among them, accommodation recesses 110 are formed between the opposite sides of the rear shell base body 11 and the support parts 12; an assembly groove 130 is provided along the length direction of the positioning part 13, and the assembly groove 130 is located inside the accommodation recess 110.

[0030] In this embodiment, the length direction of the assembly groove 130 is the same as that of the receiving recess 110.

[0031] The panel fitting 20 is embedded and installed on the front surface of the back shell base 11. The opposite sides of the panel fitting 20 are respectively disposed in the receiving recesses 110. At this time, the opposite sides of the panel fitting 20 respectively abut against the supporting portions 12.

[0032] On the back surfaces of the opposite sides of one end of the panel fitting 20, there are inserted recesses 21. On the back surfaces of the opposite sides of the other end of the panel fitting 20, there are connected insertion feet 22, and the ends of the insertion feet 22 protrude beyond the end surface of the panel 20. The opposite sides of the panel fitting 20 are respectively provided with openings 23 arranged in a semicircular shape, so that the panel fitting 20 is generally arranged in an "H" shape.

[0033] When adjacent panel fittings 20 are spliced, the insertion feet 22 of one panel fitting 20 are fitted and inserted into the inserted recesses 21 of the other panel fitting 20. At this time, the openings 23 of the adjacent two panel fittings 20 are matched to form a complete circular through hole, and the bottom end of the speaker 30 is passed through the circular through hole.

[0034] In this embodiment, as Figure 6 shown, on the back surfaces of the opposite sides of the panel fitting 20, there are respectively convex ribs 24 protruding. The convex ribs 24 are used for inserting into the assembly groove 130 to improve the assembly accuracy between the panel fitting 20 and the back shell 10, and effectively improve the convenience during assembly. Compared with the integral speaker panel of the traditional sound column, the present utility model has a spliceable panel fitting 20. Multiple panel fittings 20 are spliced with each other to form a speaker panel, and the length and width can be easily adjusted by changing the number of panel fittings 20 to adapt to different environments and applications; at the same time, each panel fitting 20 can also be separately packaged and transported, reducing the overall size and weight, and facilitating handling and movement.

[0035] Further, in this embodiment, through holes 25 are respectively provided on the opposite sides of the panel fitting 20. The through holes 25 are arranged opposite to the assembly groove 130. By passing a screw through the through hole 25 and screwing it into the interior of the assembly groove 130, the fixed connection between the panel fitting 20 and the back shell 10 can be realized. During this process, since the opposite side walls of the assembly groove 130 have sufficient rigidity and clamping force, they will clamp the screw rod portion, thereby preventing the screw from further rotating or moving; when the screw is completely tightened and fixed in the assembly groove 130, a firm connection is formed between the panel fitting 20 and the back shell 10.

[0036] Further, in this embodiment, connection holes 26 are respectively provided on the opposite sides of the panel fitting 20. The connection holes 26 are used for mating connection with the speaker 30.

[0037] The above-mentioned modular housing structure of the sound column has a simple structure and is convenient for assembly. The panel fittings 20 of a unified specification are adopted, and multiple panel fittings 30 are spliced with each other to form a speaker panel. The length and width can be easily adjusted by changing the number of panel fittings 20 to adapt to different environments and applications. At the same time, each panel fitting 20 can also be individually packaged and transported, reducing the overall size and weight and facilitating handling and movement.

[0038] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0039] The above-described embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
