DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] Example

[0022] like Figure 1 As shown, Figure 1 Shown is a schematic diagram of a front view of a loudspeaker in an embodiment;

[0023] The device comprises a housing 10 in which a speaker body is arranged. A dustproof net 20 is detachably arranged on the housing 10 .

[0024] The dustproof net 20 has a dustproof effect on the speaker, preventing dust from affecting the sound of the speaker. The detachable setting makes it easy to remove and install the dustproof net 20 from the housing 10 when cleaning it, and the operation is convenient and quick without disassembling the entire speaker.

[0025] like Figure 2 As shown, Figure 2 Shown is a side cross-sectional schematic diagram of a loudspeaker in an embodiment;

[0026] The housing 10 includes a main cavity 11 in which the speaker body is installed and a heat dissipation cavity 12 located at the upper and lower ends of the main cavity 11. A through hole 13 connected to the outside is opened on the corresponding side wall of the heat dissipation cavity 12, and a plurality of through holes 14 connected to the heat dissipation cavity 12 are opened on the side wall of the main cavity 11 close to the heat dissipation cavity 12.

[0027] A fan 15 is also disposed in the heat dissipation cavity 12 .

[0028] The heat dissipation cavity 12 is used to dissipate heat from the speaker body to ensure the service life of the speaker body. The connected through hole 13 and through hole 2 14 are used to exchange air between the main cavity 11 and the outside, thereby dissipating heat.

[0029] The fan 15 can be arranged in the heat dissipation cavity 12 at the upper end, or in the heat dissipation cavity 12 at the lower end, or in both heat dissipation cavities 12. The fan 15 serves to increase the speed of air exchange and quickly dissipate heat.

[0030] like Figure 2 , Figure 3 As shown, Figure 2 FIG. 1 is a schematic side cross-sectional view of a loudspeaker in an embodiment. Figure 3 It is shown that Figure 2 A schematic diagram of the enlarged structure in FIG.

[0031] The dustproof net 20 can be detachably installed on a side wall of the shell 10. The side wall of the shell 10 is symmetrically provided with a mounting portion 21, and the mounting portion 21 includes a slot formed by an L-shaped plate. The upper and lower ends of the dustproof net 20 are provided with extension sections 22 that match the slot and are snap-fitted to the position of the mounting portion 21.

[0032] It also includes a connecting structure 30, which includes a rectangular hole 1 opened on the extension section 22 of the dustproof net 20, and a rectangular block 31 movably inserted into the rectangular hole 1. A rectangular hole 2 is opened at the mounting portion 21 of the shell 10 at a position corresponding to the rectangular hole 1 for the rectangular block 31 to slide up and down. The rectangular block 31 can be pushed into the rectangular hole 1 to connect the shell 10 and the dustproof net 20 through a driving member connected thereto, or detached from the rectangular hole 1 to realize the disassembly of the dustproof net 20.

[0033] The extension section 22 of the dustproof net 20 is matched and engaged with the slot of the shell 10 to achieve the initial connection and engagement between the dustproof net 20 and the shell 10, and the engagement state is fixed or released by setting a connecting structure 30, thereby achieving the installation and removal of the dustproof net 20.

[0034] When the driving member drives the rectangular block 31 into the rectangular hole one, the connection between the shell 10 and the dustproof net 20 is realized. When the driving member drives the rectangular block 31 out of the rectangular hole one, the dustproof net 20 is disassembled. Specifically, by manually adjusting the driving member, the rectangular block 31 can be driven to move up and down inside the rectangular hole two, so that the rectangular block 31 enters or leaves the rectangular hole one, thereby achieving the purpose of quick disassembly.

[0035] The connection structure 30 also includes a threaded rod 32 and a threaded sleeve 33. The threaded rod 32 is arranged in the rectangular hole 2, and the threaded sleeve 33 is arranged inside the heat dissipation cavity 12. The bottom end of the threaded rod 32 is fixedly connected to the rectangular block 31, and the threaded sleeve 33 is threadedly sleeved on the outside of the threaded rod 32. The heat dissipation cavity 12 is also provided with a bevel gear 1 34 and a bevel gear 2 35 that mesh with each other. The vertically arranged bevel gear 1 34 is fixedly connected to the threaded sleeve 33, and the horizontally arranged bevel gear 2 35 is rotatably connected to the side wall of the heat dissipation cavity 12, and the shaft end extends to the outside and is provided with a handle 36.

[0036] By rotating the handle 36, the bevel gear 2 35 is driven to rotate, and the bevel gear 2 35 drives the bevel gear 1 34 meshing with it to rotate, thereby driving the threaded sleeve 33 to rotate, and causing the threaded rod 32 threadedly connected to the threaded sleeve 33 to move up and down, and the threaded rod 32 drives the rectangular block 31 connected to it to move up and down.

[0037] The rectangular block 31 having a rectangular shape can prevent the threaded rod 32 from rotating together with the threaded sleeve 33 when the threaded sleeve 33 rotates, thereby realizing the up and down movement of the threaded rod 32 , that is, the up and down movement of the rectangular block 31 .

[0038] Working principle: When the dust screen 20 needs to be cleaned, the device first disassembles it, and the disassembly steps are as follows: turn the handle 36 to drive the bevel gear 2 35 to rotate, and the bevel gear 2 35 drives the bevel gear 1 34 meshing with it to rotate, thereby driving the threaded sleeve 33 to rotate, and the threaded rod 32 threadedly connected to the threaded sleeve 33 moves upward, and the threaded rod 32 drives the rectangular block 31 connected to it to move upward, so that the rectangular block 31 is completely disengaged from the rectangular hole 1, and then the dust screen 20 is pulled outward until the extension section 22 of the dust screen 20 is disengaged from the slot of the mounting portion 21.

[0039] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
