[0015] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0016] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate directions or positional relationships based on the attached Figure 1 The directions or positional relationships shown are only for the convenience of describing the present invention, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0017] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0018] In order to solve the above technical problems, Figure 1-4As shown, the utility model designs a dust cover for a vehicle-mounted speaker, comprising a supporting body 1, a positioning ring 2, and a dustproof net 3. The supporting body 1 is in a circular ring shape and can be adaptively adjusted to fit the shape of the speaker cover. An annular mounting groove 4 is provided on the front side of the supporting body 1. The positioning ring 2 is fixedly installed in the annular mounting groove 4 and is used to fix the dustproof net 3 so that it covers the inner hole of the supporting body 1. The dustproof net 3 is provided with a plurality of mesh holes. Specifically, a bolt connection hole 5 is provided on the annular mounting groove 4 of the supporting body 1, and the four bolt connection holes 5 are evenly spaced around the circumferential direction. The positioning ring 2 is provided with four bolt insertion holes 6 corresponding to the bolt connection holes 5. During assembly, the dustproof net 3 is fitted on the annular mounting groove 4 so that the small holes on its four sides correspond to the bolt connection holes 5. The bolt insertion holes 6 are step holes. After the bolts are inserted, they pass through the mounting small holes of the dustproof net 3 and are threadedly connected with the bolt connection holes 5 on the annular mounting groove 4 to fix the positioning ring 2. The positioning ring 2 restricts the dustproof net 3 on the inside so that it cannot be detached. The bolt connection method is stable and makes the disassembly and assembly of the positioning ring 2 more convenient, so that the dustproof net 3 can be disassembled and replaced.

[0019] Furthermore, a limiting protrusion 7 is also provided in the annular mounting groove 4 of the support body 1, and the dustproof net 3 is provided with a limiting hole adapted to the limiting protrusion 7. When the dustproof net 3 is placed before installing the positioning ring 2, the limiting hole is first aligned with the limiting protrusion 7 to achieve pre-positioning, which is convenient for subsequent bolt installation.

[0020] Furthermore, a magnetic connection layer 8 is provided at the rear of the support body 1. The magnetic connection layer 8 is in a circular ring shape and coaxially corresponds to the support body 1. The support body 1 can be fixedly connected to the outer cover shell of the speaker through the magnetic connection layer 8, so that the dust cover can be directly fitted and installed on the outside of the speaker cover of the adaptable vehicle. The magnetic connection method is convenient for disassembly and assembly, making it easier to clean the dust net 3.

[0021] Furthermore, it also includes a decorative ring 9, which is installed on the front side of the positioning ring 2 by magnetic connection. The decorative ring 9 and the supporting body 1 are integrated into one, and preferably made of metal, which has a good metal texture and high structural strength. The installation of the decorative ring 9 can hide the positioning ring 2 and the bolts, making the overall design simple, beautiful and practical.

[0022] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made by technicians in the relevant technical field based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
