Description

Technical Field

[0001] This utility model relates to the field of acoustic device protective mesh technology, and in particular to an acoustic device protective mesh. Background Technology

[0002] Acoustic device protective nets serve to protect acoustic devices from dust and water. They are commonly used as the outer layer of protection for loudspeakers such as headphones, effectively preventing dust and water droplets from affecting the lifespan of high-end equipment like headphones. Existing acoustic protective nets mainly include rigid shell types and mesh fabric types. Rigid shell types achieve sound transmission and protection through perforation, and the mesh structure is relatively stable, but the dust and water protection effect is poor. Mesh fabric types are mostly textile products, with fine mesh holes and better dust and water protection effects. When the structure is loose, the mesh hole structure becomes unstable and easily altered by external stretching forces, leading to increased deformation of local mesh holes, uneven distribution of mesh holes, and inconsistent hole sizes, affecting its waterproof and dustproof effects. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides an acoustic device protective mesh that stabilizes the mesh structure and ensures stable mesh size and uniform mesh distribution.

[0004] Technical solution: To achieve the above objectives, the present invention provides an acoustic device protective mesh, comprising crisscrossed warp and weft threads, wherein uniformly distributed mesh openings are formed between the warp and weft threads;

[0005] The meridian includes a plurality of first meridians and a plurality of second meridians, with the plurality of first meridians and the plurality of second meridians arranged alternately.

[0006] The parallels of latitude include a plurality of first parallels of latitude and a plurality of second parallels of latitude, with the plurality of first parallels of latitude and the plurality of second parallels of latitude arranged alternately.

[0007] The first warp and the plurality of weft threads are interwoven alternately in a series of vertical and horizontal alternations. The second warp passes under the weft thread once after passing over a fixed number of weft threads.

[0008] The first weft thread and the plurality of warp threads are interwoven alternately in sequence, and the second weft thread passes under the warp thread once after passing over a fixed number of warp threads.

[0009] Furthermore, several second meridians are arranged between two adjacent first meridians, and several second parallels are arranged between two adjacent first parallels.

[0010] Furthermore, the number of second meridians between adjacent first meridians is the same as the number of second parallels between adjacent first parallels.

[0011] Furthermore, the two first meridians are arranged close to each other, and the two first meridians respectively pass over the upper and lower sides of the same latitude line.

[0012] Furthermore, the two first parallels of latitude are arranged close to each other, and the two first parallels of latitude respectively pass over the upper and lower sides of the same meridian.

[0013] Furthermore, the warp and weft threads are single filaments of the same diameter.

[0014] Beneficial Effects: This utility model provides an acoustic device protective mesh. A first mesh structure, woven from first warp and first weft threads, forms a robust and stable structure. A second mesh structure, woven from second warp and second weft threads, forms a smooth and flat surface with good sound transmission. These two types of mesh are woven together to form a composite, interwoven mesh structure. The overall mesh is primarily composed of the smooth, flat second mesh with good sound transmission, while the internal composite interwoven first mesh provides restraint, fixation, and increased strength. This enhances the overall protective mesh's tensile and deformation resistance, stabilizes the mesh structure, and ensures uniform mesh size and distribution, guaranteeing excellent dustproof and waterproof performance as well as sound transmission. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of one embodiment of the protective wire mesh of the acoustic device of this utility model. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] As attached Figure 1 The acoustic device protective mesh includes crisscrossed warp and weft threads, with uniformly distributed mesh openings 1 formed between the warp and weft threads; theoretically, the formed mesh openings are uniformly distributed and of the same size.

[0018] The warp includes a plurality of first warp 2 and a plurality of second warp 3, arranged alternately. The weft includes a plurality of first weft 4 and a plurality of second weft 5, arranged alternately. The first warp 2 and the plurality of wefts are interwoven vertically, with the second warp 3 passing under a fixed number of wefts once. The first weft 4 and the plurality of warp are interwoven vertically, with the second weft 5 passing under a fixed number of warps once. That is, the first mesh structure is formed by the weaving of the first warp 2 and the first weft 4 (gray area in the figure), and the second mesh structure is formed by the weaving of the second warp 3 and the second weft 5 (white area in the figure), with both weaving simultaneously to form a composite interwoven mesh structure. The first warp 2, through its interlacing with all the wefts, strengthens the connection with the wefts and improves its positional stability in the weft direction. Similarly, the first weft thread 4 enhances its positional stability in the warp direction, making the first wire mesh structure woven from both strong and stable. Its composite weaving acts as a skeletal mesh within the entire protective wire mesh, constraining the movement range of the second warp thread 3 and the second weft thread 5, thereby limiting variations in mesh size. Meanwhile, the second warp thread 3 and the second weft thread 5, by reducing the number of interlacing passes, improve the smoothness and flatness of the wire mesh surface, ensuring good sound transmission. This results in the overall wire mesh primarily composed of a smooth, flat second wire mesh with good sound transmission, while the internal composite weaving of the first wire mesh provides positioning, fixation, and increased strength. This enhances the overall tensile and deformation resistance of the protective wire mesh, stabilizes the mesh structure, and ensures uniform mesh size and distribution, guaranteeing excellent dustproof and waterproof performance as well as sound transmission.

[0019] A plurality of second meridians 3 are arranged between two adjacent first meridians 2, and a plurality of second latitudes 5 are arranged between two adjacent first latitudes 4. Preferably, the number of second meridians 3 between adjacent first meridians 2 is the same as the number of second latitudes 5 between adjacent first latitudes 4. This results in the first wire mesh forming a large square mesh, inside which a second wire mesh forms a uniform and fine smaller square mesh. The larger external square mesh constrains and fixes the internal smaller square mesh structure, achieving the fixation of the partitioned mesh on the wire mesh surface. The stable, uniformly sized, evenly distributed, and relatively dense mesh structure can reduce the reflection and scattering phenomena caused by changes in mesh size during sound wave propagation, thus improving sound transmission.

[0020] Example: Two first warp threads 2 are arranged close together, and each first warp thread 2 passes over the upper and lower sides of the same weft thread. Two first weft threads 4 are arranged close together, and each first weft thread 4 passes over the upper and lower sides of the same warp thread. Through double-sided interlacing and locking, the stability of the first wire mesh structure is further enhanced, thereby further strengthening the overall stability of the protective wire mesh structure.

[0021] Preferably, the warp and weft threads are monofilaments of the same diameter. Polyester monofilaments are preferred, as they possess high strength and abrasion resistance.

[0022] Prioritize weaving similar first warp threads 2 close together and similar first weft threads 4 close together. Correspondingly, the diameter of the first warp thread 2 is half the diameter of the second warp thread 3, the diameter of the first weft thread 4 is half the diameter of the second weft thread 5, and the diameter of the second warp thread 3 is the same as the diameter of the second weft thread 5.

[0023] Based on the double-sided interlacing and locking mechanism, at the cross-shaped node where the double first warp 2 and double first weft 4 intertwine, four fine filaments are tightly interwoven, leaving no gaps at the center of the interlacing point, thus forming a stable node. By enhancing the stability of the first wire mesh structure node, the stability of the first wire mesh structure is further enhanced, thereby further strengthening the overall stability of the protective wire mesh structure. Using single filaments of half the wire diameter effectively ensures that the size and spacing of the mesh openings at the boundaries between the first and second wire meshes are consistent with the size and spacing of the mesh openings within the second wire mesh, thus ensuring consistent mesh size and spacing throughout the overall protective wire mesh.

[0024] To further enhance antistatic capabilities, an antistatic agent can be added to the threads used to weave the overall protective mesh, or the threads forming the first mesh section can be replaced with conductive, flexible monofilaments to prevent the accumulation of static charge.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
