Technical Field

[0001] This utility model relates to the field of dustproof mesh technology, specifically a dustproof mesh for loudspeakers. Background Technology

[0002] Speaker dust filters are crucial components that protect speaker units from dust and foreign objects. To improve acoustic performance and mechanical stability, foam sealing gaskets are typically added to the edges of the dust filter frame.

[0003] Existing foam is directly pasted onto the outside of the dustproof mesh frame. Over time, the foam will age. When it needs to be replaced, it can only be removed by force. This process not only damages the surface of the dustproof mesh frame, but is also time-consuming and laborious. To address this problem, the inventor designed a dustproof mesh for loudspeakers.

[0025] Please see Figures 1 to 4The present invention provides an embodiment of a dustproof mesh for a loudspeaker, the dustproof mesh comprising a mounting frame 1, a limiting ring 2, a dustproof mesh body 3, a lifting member 4, a limiting member 5, and a mounting member 6; the limiting ring 2 is fixed inside the mounting frame 1, the dustproof mesh body 3 is attached to the surface of the limiting ring 2, the lifting member 4 is located outside the mounting frame 1, the limiting member 5 is snapped onto the outside of the mounting frame 1, and the mounting member 6 connects the mounting frame 1 and the lifting member 4;

[0026] Mounting frame 1 is the basic support frame for the dustproof net. The limiting ring 2 is used to accurately position and support the dustproof net body 3. The dustproof net body 3 is used to block dust and foreign objects from entering the speaker, while allowing sound to pass through.

[0027] Mounting component 6 includes positioning posts 61, mounting posts 62, limiting posts 66, and movable plates 65. Positioning posts 61 are fixed on the surface of mounting frame 1 away from the limiting ring 2. Positioning posts 61 are arranged in a circular array on the surface of mounting frame 1 with the center of mounting frame 1 as the reference point. There are four sets of positioning posts 61. Mounting posts 62 are sleeved on the outside of positioning posts 61. Limiting posts 66 are inserted into the inside of positioning posts 61 and mounting posts 62. Movable plates 65 are fixed on the outer surface of limiting posts 66.

[0028] The positioning post 61 provides insertion guidance and positioning for the mounting post 62, which is used to place the protective sleeve 41 outside the mounting frame 1. The limiting post 66 is used to connect the positioning post 61 and the mounting post 62 together, and the movable plate 65 facilitates changing the position of the limiting post 66.

[0029] The lifting component 4 includes a protective sleeve 41 and foam 42; the protective sleeve 41 is wrapped around the outside of the foam 42, and the surface of the protective sleeve 41 is glued and fixed to the surface of the mounting post 62.

[0030] Foam 42 is used to absorb vibration and cushion impact, while protective sleeve 41 is used to wrap foam 42 to prevent wear and extend the service life of foam 42.

[0031] The limiting component 5 includes a fixing plate 51 and a first connecting post 52; the fixing plate 51 is attached to the surface of the mounting frame 1, and the first connecting post 52 is fixed to the lower surface of the fixing plate 51 located on the outside, and the bottom surface of the first connecting post 52 is attached to the surface of the mounting frame 1.

[0032] The fixing plate 51 is used to support and install the first connecting post 52 and the second connecting post 53, thereby forming a clamp structure. The first connecting post 52 is used to support and install the mounting plate 54.

[0033] A second connecting post 53 is fixed on the lower inner surface of the fixing plate 51. The height of the second connecting post 53 is higher than that of the first connecting post 52, and the lower surface of the second connecting post 53 is in contact with the surface of the dustproof net body 3.

[0034] The second connecting post 53 presses against the surface of the dustproof net body 3, thereby confining the dustproof net body 3 inside the mounting frame 1;

[0035] A mounting plate 54 is fixed to the outer surface of the bottom end of the first connecting column 52, and screws 55 are threadedly connected to the mounting plate 54 and the mounting frame 1.

[0036] Mounting plate 54 is used to connect with screw 55, thereby fixing the limiting member 5 to the outside of mounting frame 1;

[0037] The mounting column 62 has a mounting groove 63 inside, and a spring 64 is fixed inside the mounting groove 63. The spring 64 is fixed to the surface of the movable plate 65.

[0038] Mounting slot 63 is used to receive and install spring 64. Spring 64 provides elastic force to movable plate 65, which can quickly drive limit post 66 to move to the required position.

[0039] The movable plate 65 is rotatably connected to the inner side of the rotating column 67, and the positioning column 61 has a limit hole 68 inside.

[0040] The rotating column 67 is used to insert into the limiting hole 68, thereby limiting the movable plate 65 to the desired position;

[0041] Working principle: When foam 42 needs to be replaced, a pushing force is applied to the movable plate 65, causing the limiting post 66 to disengage from the interior of the positioning post 61. Then, a rotational force is applied to the rotating post 67, causing it to align with the limiting hole 68. The force applied to the movable plate 65 is then released, and the rotating post 67 is now locked inside the positioning post 61. Using the above method, all the limiting posts 66 are disengaged from the interior of the positioning post 61 in sequence. Then, a pulling force is applied to the foam 42, causing the mounting post 62 to disengage from the exterior of the positioning post 61. The mounting post 62 with the new protective sleeve 41 is then inserted into the interior of the positioning post 61. A pulling force is then applied to the movable plate 65, and a rotational force is applied to the rotating post 67, causing it to retract back into the interior of the movable plate 65. The force applied to the movable plate 65 is then released, and under the elastic force of the spring 64, the limiting post 66 is inserted into the interior of the positioning post 61 and the mounting post 62.

[0042] When it is necessary to replace the dustproof net body 3, turn the screw 55 from inside the mounting plate 54, and then apply an upward pulling force to the first connecting post 52 and the second connecting post 53 to make the limiting member 5 disengage from the outside of the mounting frame 1. After removing the dustproof net body 3 from inside the mounting frame 1, put the new dustproof net body 3 into the inside of the mounting frame 1. Under the restriction of the limiting ring 2, the dustproof net body 3 can be quickly installed in the required position. Then insert the first connecting post 52 and the second connecting post 53 into the outside of the mounting frame 1, and turn the screw 55 into the mounting plate 54 and the inside of the mounting frame 1.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
