Description

Technical Field

[0001] This utility model relates to the field of speaker grille technology, and in particular to a replaceable dustproof speaker grille. Background Technology

[0002] With technological advancements, audio equipment is widely used in homes, cars, and outdoors. However, dust, hair, and other debris can easily penetrate the speaker, affecting sound quality and lifespan. As a key component for speaker protection, the performance and ease of use of dustproof speaker grilles are becoming increasingly important. Replaceable dustproof speaker grilles, with their flexible maintenance advantages, represent an innovative direction for improving the durability of audio equipment and enhancing the user experience.

[0003] A search revealed Chinese patent publication number CN213960320U, which discloses a polycarbonate sheet for speaker grilles. The speaker grille body comprises a polycarbonate sheet, an annular rubber pad, a sponge pad, and a dustproof mesh. An annular groove is formed on the inner wall of the annular rubber pad, and the polycarbonate sheet and dustproof mesh are disposed inside the annular rubber pad. This invention uses a polycarbonate sheet instead of the traditional metal stamping process for speaker grille panels, reducing costs and making it easier to create openings on the polycarbonate sheet. The edges of the polycarbonate sheet are then snapped into the annular groove on the inner wall of the annular rubber pad for adhesive fixation, thus providing auxiliary fixation and protection for the edges of the polycarbonate sheet and improving its service life. Furthermore, the dustproof mesh below the polycarbonate sheet effectively prevents dust from entering the speaker and affecting the internal electrical components.

[0004] The aforementioned patent specification mentions "auxiliary adhesive fixing, which can provide auxiliary fixing and protection for the edges and corners of the polycarbonate sheet, thereby improving the service life of the polycarbonate sheet. Furthermore, a dustproof mesh is provided under the polycarbonate sheet to effectively prevent airborne dust from entering the speaker through the polycarbonate sheet and affecting the electrical components inside the speaker." While this provides auxiliary fixing and protection for the edges and corners of the polycarbonate sheet and improves its service life, and the dustproof mesh under the polycarbonate sheet effectively prevents airborne dust from entering the speaker and affecting the electrical components inside the speaker, the use of an adhesive-bonded mesh makes it impossible to replace, reducing maintenance efficiency. Therefore, a replaceable dustproof speaker mesh is proposed to solve the above problems. Utility Model Content

[0017] The outer surface of the coarse filter protective layer is slidably connected to the outside of the opening and closing ring, and the outer surface of the support and fixing layer is slidably connected to the outside of the connecting ring.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the linkage design of sliding block, locking block and buffer spring allows disassembly to be completed with one click, improving replacement efficiency.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1 to 3 This utility model provides an embodiment of a replaceable dustproof speaker grille, including a fixing ring 1. The fixing ring 1 is the basic frame of the grille, providing overall support. Its outer contour is adapted to the edge of the speaker to ensure that the grille is firmly fitted after installation and to prevent the grille from shifting due to external force collision or vibration. The fixing ring 1 is provided with a quick-release mechanism 2. The quick-release mechanism 2 can realize the quick disassembly and installation of the protective mechanism 3 through simple operation, which significantly improves maintenance efficiency. The quick-release mechanism 2 is provided with a protective mechanism 3 inside. The protective mechanism 3 is used to undertake core functions such as dust prevention and sound quality optimization, protecting the speaker from dust damage.

[0030] The quick-release mechanism 2 includes a sliding block 21. The user can activate the unlocking function of the quick-release mechanism 2 by pressing the sliding block 21. The external sliding connection of the sliding block 21 is inside the fixed ring 1. The external fixed connection of the sliding block 21 is a limit post 24. The limit post 24 is used to limit the movement of the sliding block 21 to prevent it from moving too much and causing damage to the mechanism. At the same time, it is a support point for the buffer spring 23. The buffer spring 23 is sleeved on the outside of the limit post 24. The buffer spring 23 is used to absorb and release elastic potential energy during the disassembly process, assist the sliding block 21, and provide thrust outside the connecting ring 251. The external fixed connection of the sliding block 21 is a locking block 22. The locking block 22 is used to lock the opening and closing component 25 to prevent the protective mechanism 3 from loosening and falling off during use. The external opening and closing component 25 is provided on the locking block 22. The opening and closing component 25 is responsible for clamping and releasing the protective mechanism 3 through the cooperation of the connecting ring 251 to achieve stable clamping and quick release of the protective mechanism 3.

[0031] The opening and closing assembly 25 includes a connecting ring 251, which is movably connected to the fixed ring 1. Under the buffer spring 23, it can move radially along the fixed ring 1, driving the opening and closing ring 252. The outside of the connecting ring 251 is slidably connected to the outside of the locking block 22, and the outside of the connecting ring 251 is slidably connected to the outside of the fixed ring 1. The inside of the connecting ring 251 is provided with a hole, and the outside of the hole is slidably connected to the opening and closing ring 252. The opening and closing ring 252 is used to directly contact the protective mechanism 3. By sliding the connecting ring 251, the coarse filter protective layer 31 can be tightened and loosened. The operation is flexible and the clamping force is stable.

[0032] The buffer spring 23 is fixedly connected to the outside of the connecting ring 251, and the other end of the buffer spring 23 is fixedly connected to the outside of the sliding block 21. The limiting post 24 is slidably connected to the inside of the sliding block 21.

[0033] Reference Figure 1 , Figure 4 and Figure 5The protective mechanism 3 includes a coarse filter protective layer 31, which is used to block larger particles of debris such as dust, hair, and debris, reducing the filtration burden on subsequent filter layers and extending the service life of the entire protective mechanism 3. The coarse filter protective layer 31 is externally slidably connected to the outside of the quick-release mechanism 2. A fine filter dustproof layer 32 is fixedly connected to the outside of the coarse filter protective layer 31. The fine filter dustproof layer 32 is used to filter fine dust particles, improving the dustproof effect and protecting the precision components inside the speaker. An acoustic optimization layer 33 is fixedly connected to the outside of the fine filter dustproof layer 32. 33 adopts special materials and structural design to reduce attenuation and distortion during sound propagation, ensuring clear and full sound quality without affecting the speaker's sound output. The external fixed connection of the acoustic optimization layer 33 is a support fixing layer 34, which is used to provide structural support for the protective mechanism 3, maintain the relative position stability of each layer, ensure the tight fit of the multi-layer protective structure, and facilitate the fixing with the quick-release mechanism 2. The external sliding connection of the coarse filter protective layer 31 is on the outside of the opening and closing ring 252, and the external sliding connection of the support fixing layer 34 is on the outside of the connecting ring 251.

[0034] Working principle: The fixed ring 1 serves as the basic frame of the mesh cover. The protective mechanism 3 is aligned with the fixed ring 1, causing the supporting fixing layer 34 to adhere to the outside of the connecting ring 251. The coarse filter protective layer 31 is aligned with the opening and closing ring 252. Pushing the opening and closing ring 252 allows it to slide along the internal holes of the connecting ring 251 until the opening and closing ring 252 clamps the coarse filter protective layer 31. At this point, the protective mechanism 3 is initially fixed to the quick-release mechanism 2. The connecting ring 251 and the opening and closing ring 252 together constitute an external constraint on the protective mechanism 3. Pressing the sliding block 21 causes it to slide inside the fixed ring 1, driving the limiting post 24 and the locking mechanism. When block 22 moves synchronously, and sliding block 21 is pressed, buffer spring 23 is compressed, accumulating elastic potential energy. During the movement of locking block 22, the limit on opening and closing ring 252 is released, allowing opening and closing ring 252 to slide freely in the hole of connecting ring 251. At the same time, under the elastic action of buffer spring 23, connecting ring 251 moves away from the center of fixed ring 1, causing opening and closing ring 252 to move together. When this happens, the protective mechanism 3 can be directly removed from fixed ring 1, completing the disassembly of the mesh cover. The opening and closing ring 252 and connecting ring 251 can be pried apart to clean or replace the protective mechanism 3.

[0035] During normal use, the coarse filter protective layer 31 first blocks larger particles of debris such as dust and hair; the fine filter dustproof layer 32 further filters out tiny dust particles; the acoustic optimization layer 33 ensures that the sound quality is not affected during sound propagation and reduces sound wave attenuation; and the support and fixing layer 34 maintains the structural stability of the entire protective mechanism 3 and ensures that each layer works closely together.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
