[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figure 1-3As shown, a loudspeaker includes a loudspeaker body 1 and a loudspeaker grille 2. The loudspeaker body 1 has a slot 2 11 at one end. The loudspeaker grille 2 is located in front of the slot 2 11, and two magnets 2 6 are fixedly embedded in the inner wall of the slot 2 11. Two magnets 1 4 corresponding to the magnets 2 6 are fixedly connected to the inner wall of the loudspeaker grille 2 on the side close to the magnets 2 6. The two magnets 2 6 are a first movable magnetic strip and a second movable magnetic strip, and the two magnets 1 4 are a first fixed magnetic strip and a second fixed magnetic strip, respectively. The first movable magnetic strip and the first fixed magnetic strip are magnetically attracted to each other, and the first movable magnetic strip and the second fixed magnetic strip are magnetically repelled. The second movable magnetic strip and the second fixed magnetic strip are magnetically attracted to each other, and the second movable magnetic strip and the first fixed magnetic strip are magnetically repelled.

[0023] When the speaker grille 2 is installed on the front side of the amplifier body 1, the magnet 4 is located inside the slot 11. The cooperation between the magnet 4 and the slot 11 can greatly improve the stability of the speaker grille 2 after installation and reduce the phenomenon of vertical and horizontal displacement of the speaker grille 2 on the front side of the amplifier body 1.

[0024] The speaker is fixedly connected inside the main body 1 of the loudspeaker. The speaker grille 2 is located on the front side of the speaker. During installation, the user moves the speaker grille 2 so that the magnet 4 on the speaker grille 2 is inside the slot 11. Then, the user rotates the speaker grille 2 so that the first movable magnetic strip and the first fixed magnetic strip attract each other magnetically, and the second movable magnetic strip and the second fixed magnetic strip attract each other magnetically. The speaker grille 2 is quickly installed on the front side of the main body 1 of the loudspeaker by using the attraction between the magnet 4 and the magnet 6.

[0025] During disassembly, rotating the speaker grille 2 causes the first movable magnetic strip and the second fixed magnetic strip to repel each other magnetically, and the second movable magnetic strip and the first fixed magnetic strip to repel each other magnetically. Utilizing the repulsive force between magnet 4 and magnet 6, the speaker grille 2 can be directly pushed out, thus enabling the speaker grille 2 to be disassembled simply and quickly.

[0026] like Figure 3 As shown, a sealing gasket 5 is fixedly connected to the side of the speaker grille 2 near the amplifier body 1. When the magnet 4 and magnet 6 are attracted by magnetism during use, the sealing gasket 5 can improve the sealing between the speaker grille 2 and the amplifier body 1.

[0027] like Figure 2-3 As shown, a tight ring 10 is fixedly connected to the side of the speaker grille 2. The outer diameter of the tight ring 10 is larger than the outer diameter of the slot 11. In use, when the speaker grille 2 is magnetically connected to the inside of the slot 11 by magnet 4 and magnet 6, the tight ring 10 can improve the sealing between the speaker grille 2 and the surface of the amplifier body 1, thereby reducing the amount of dust entering the inside of the device through the gap between the amplifier body 1 and the speaker grille 2.

[0028] like Figure 2-3 As shown, the speaker grille 2 has at least one rotating groove 3 on the side away from the amplifier body 1. In use, the user can easily remove the speaker grille 2 by rotating the rotating groove 3 to clean or replace it, which greatly saves time and effort and improves maintenance efficiency.

[0029] like Figure 4 As shown, the sealing gasket 5 has a groove 9 inside. A locking block 8 is slidably connected inside the groove 9 on the side facing the amplifier body 1. A spring 12 is installed inside the groove 9 and is connected to the locking block 8. The locking slot 11 has a locking slot 7 corresponding to the locking block 8 inside. The side of the locking block 8 near the locking slot 7 has a first inclined surface. The inside of the locking slot 7 has a second inclined surface corresponding to the locking block 8. When in use, the sealing gasket 5 rotates, causing the locking block 8 to move inside the locking slot 11. When the locking block 8 moves to the inside of the locking slot 7, the spring 12 located inside the groove 9 stores elastic force, causing the locking block 8 to be ejected into the locking slot 7. At that time, the locking block 8 and the locking slot 7 cooperate to play a limiting role. When the locking block 8 enters the inside of the locking slot 7, the magnet 26 and the magnet 14 are aligned, so that the magnet 14 and the magnet 26 can be easily and accurately aligned.

[0030] like Figure 3 As shown, magnet 26 and magnet 14 have an arc-shaped structure. By setting magnet 26 and magnet 14 into an arc-shaped structure, magnet 26 and magnet 14 can have a larger area inside the slot 211. When in use, magnet 26 and magnet 14 have a larger contact area when adsorbing, which makes the adsorption force stronger and more stable, while reducing loosening or displacement caused by uneven adsorption force.

[0031] The working principle of this utility model is as follows: During installation, the user moves the speaker grille 2 so that the magnet 4 on the speaker grille 2 is located inside the slot 11. Then, the speaker grille 2 is rotated so that the first movable magnetic strip and the first fixed magnetic strip are magnetically attracted to each other, and the second movable magnetic strip and the second fixed magnetic strip are magnetically attracted to each other. The speaker grille 2 is quickly installed on the front side of the amplifier body 1 by using the attraction between the magnet 4 and the magnet 6.

[0032] During disassembly, rotating the speaker grille 2 causes the first movable magnetic strip and the second fixed magnetic strip to repel each other magnetically, and the second movable magnetic strip and the first fixed magnetic strip to repel each other magnetically. Utilizing the repulsive force between magnet 4 and magnet 6, the speaker grille 2 can be directly pushed out, thus enabling the speaker grille 2 to be disassembled simply and quickly.

[0033] In summary, this technical solution allows for the simple and quick replacement of the speaker grille 2 by adjusting the attraction and repulsion between magnet 4 and magnet 6 by rotating the speaker grille 2, thus facilitating the cleaning or maintenance of the speaker grille 2.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
