Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a dustproof mechanism for a loudspeaker. Background Art

[0002] When the speaker is in use, in order to prevent the speaker from being affected by external dust, a dustproof net is installed on the speaker to block the dust. For example, the authorization publication number CN219960830U, a speaker with a dustproof mechanism, can block most of the dust through the dustproof cloth on the cover, so that the structure can prevent dust from falling into the speaker opening when in use.

[0003] Since the dustproof net or dustproof cloth is exposed as a whole, although it provides convenience for replacing the dustproof net or dustproof cloth, when the speaker is not in use, external dust will still fall on the surface of the dustproof net or dustproof cloth, thereby accelerating the speed at which the surface of the dustproof net or dustproof cloth becomes dirty. Repeated disassembly and cleaning of the dustproof net or dustproof cloth can easily lead to wear of the dustproof net or dustproof cloth, thereby reducing the service life of the dustproof net or dustproof cloth.

[0004] Therefore, a loudspeaker dustproof mechanism is urgently needed to solve the above problems. Utility Model Content

[0023] The protection mechanism includes a protection ring 201 arranged on the side of the edge 102 away from the speaker body 101, the protection ring 201 is provided with a connection component for connecting with the edge 102, a plurality of rotating shafts 202 are rotatably connected to the protection ring 201, and a protection plate 203 is provided at one end of each rotating shaft 202 close to each other, a fixing column 205 is connected to the side of the protection ring 201 away from the edge 102 through an L-shaped fixing plate 204, and one end of each protection plate 203 close to each other is rotatably connected to the fixing column 205, and a driving mechanism for driving each protection plate 203 is provided on the protection ring 201;

[0024] It should be noted here that: through the setting of the protective mechanism, under the driving action of the driving mechanism, the protective plate 203 is used to protect the dustproof plate 103. When the speaker body 101 is not in use, the probability of external dust falling onto the dustproof plate 103 is reduced, thereby reducing the speed at which the surface of the dustproof plate 103 becomes dirty, and reducing the number of times the dustproof plate 103 is disassembled and cleaned, thereby further reducing the wear of the dustproof plate 103 and ensuring the service life of the dustproof plate 103.

[0025] It is worth noting that: as a prior art, the specific structure and working principle of the speaker body 101 have been mastered by those skilled in the art, and will not be elaborated here.

[0026] See also Figure 1 , the protective plates 203 shown in the figure are arranged in a ring array, and each protective plate 203 forms a circle when placed horizontally;

[0027] It should be noted here that: by arranging the protection plates 203 in a ring array, structural support is provided for the protection plates 203 to form a circle when placed horizontally.

[0028] See also Figure 1 , each protective plate 203 shown in the figure has an arc surface at one end away from each other, and each arc surface is matched with the inner wall of the protective ring 201;

[0029] It should be noted here that: by setting the arc surface, one end of the protection plate 203 is fitted with the inner wall of the protection ring 201, thereby improving the protection effect of the dustproof plate 103.

[0030] See also Figure 1 The connection assembly includes a plurality of countersunk holes 301 formed on a side of the protection ring 201 away from the edge 102, each countersunk hole 301 is rotatably connected with a screw 302, and one end of each screw 302 is connected to the edge 102;

[0031] It should be noted here that: by setting the connecting assembly, it is easy to install and disassemble the protective ring 201, thereby ensuring the convenience of disassembling and cleaning the dustproof plate 103.

[0032] Working principle: When the speaker body 101 is not in use, the driving mechanism drives the rotating shaft 202 to rotate. During the rotation of the rotating shaft 202, the protective plate 203 will be driven to rotate synchronously. When each protective plate 203 rotates to a horizontal state and is limited by the limiting assembly, each protective plate 203 will form a circle, thereby protecting the dustproof plate 103 and preventing external dust from falling onto the dustproof plate 103 when the speaker body 101 is not in use, thereby reducing the speed at which the surface of the dustproof plate 103 is dirty, reducing the number of times the dustproof plate 103 is disassembled and cleaned, further reducing the wear of the dustproof plate 103 and ensuring the service life of the dustproof plate 103;

[0033] When the speaker body 101 needs to be used, each protective plate 203 is rotated to be placed vertically through the driving mechanism, thereby releasing the protection of the dustproof plate 103 and ensuring the normal use of the speaker body 101.

[0034] Example 2

[0035] See also Figure 4 , this embodiment further explains Example 1, the driving mechanism in the figure includes a driving ring 401 rotatably connected to the side wall of the protective ring 201, an arc-shaped gear ring 402 is provided on the side of the driving ring 401 close to the edge 102, an end of the rotating shaft 202 away from the protective plate 203 penetrates the protective ring 201 and is fixedly connected with a gear 403, the gear 403 and the arc-shaped gear ring 402 are meshed with each other, and a limiting component for limiting the driving ring 401 is provided on the protective ring 201;

[0036] It should be noted that: through the setting of the driving mechanism, during the rotation of the driving ring 401, the arc-shaped gear ring 402 will be synchronously driven to rotate, and under the mutual meshing transmission action of the arc-shaped gear ring 402 and the gear 403, the rotating shaft 202 will be driven to rotate.

The limiting assembly shown in the figure includes an L-shaped limiting plate 501 fixedly connected to the side of the driving ring 401 away from the edge 102. A threaded rod 502 is threadedly connected to the L-shaped limiting plate 501. One end of the threaded rod 502 abuts against the protective ring 201, and the other end of the threaded rod 502 is fixedly connected to the limiting plate 503.

[0039] It should be noted here that: through the setting of the limit assembly, the threaded rod 502 is used to press the end face of the protective ring 201, thereby achieving the limitation of the drive ring 401, thereby providing a limit for the horizontal or vertical placement of each protective plate 203, further ensuring the stability of the dustproof plate 103 during protection.
