Description

Technical Field

[0001] This utility model relates to the field of speaker mesh technology, and in particular to a dustproof and waterproof speaker mesh for speakers. Background Technology

[0002] Speaker grilles, also known as speaker covers or enclosure grilles, are an important component of a speaker enclosure. They primarily cover the front of the speaker and serve multiple functions: First, speaker grilles prevent dust, small insects, or other foreign objects from entering the speaker enclosure and damaging it. They also help prevent accidental physical damage from users or external objects touching the speaker. Second, while the primary design of speaker grilles is to protect the speaker, they can also affect sound quality. A well-designed grille can minimize obstruction of sound transmission while ensuring protection, thus preserving the speaker's sound quality. Some high-quality speaker grilles even utilize special acoustic materials or structures to further optimize sound quality. Third, as part of the speaker enclosure's appearance, the design and material selection of the speaker grille affect the overall aesthetics. Many speaker manufacturers pay attention to the design of the grille to ensure it harmonizes with the overall style of the speaker, enhancing the product's overall quality. Finally, during prolonged high-power use, the speaker may generate heat; the speaker grille design can also help dissipate heat, ensuring stable speaker operation.

[0003] Currently, conventional speaker grilles are generally formed from metal sheets through stamping. However, the mesh openings in these existing speaker grilles extend directly into the interior of the speaker, allowing external moisture to easily enter and resulting in poor waterproofing. Furthermore, dust easily accumulates on the outer surface of these conventional speaker grilles, offering poor dust protection. In addition, these conventional speaker grilles cannot be integrated with the speaker's control panel; the control panel and speaker grille are installed in different locations on the speaker, resulting in an unsatisfactory integrated design that fails to meet user needs. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a dustproof and waterproof speaker grille, which can effectively solve the problems of poor waterproof and dustproof performance of existing speaker grilles and the inability to be integrated with the control panel for installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dustproof and waterproof speaker grille includes a mesh body with an outer concave and inner convex surface. A cavity for housing a control panel is formed on the outer surface of the mesh body, and a wire-passing hole is formed on the bottom surface of the cavity, extending to the inner surface of the mesh body. The mesh body includes an outer main body layer, an inner main body layer, a middle support layer, a waterproof and breathable membrane layer, and an antistatic coating. Multiple first mesh holes are formed through the inner and outer surfaces of the outer main body layer. The inner main body layer is located inside the outer main body layer, and its periphery is fixedly connected to the periphery of the outer main body layer. Multiple second mesh holes are formed through the inner and outer surfaces of the inner main body layer. The middle support layer is sandwiched between the outer main body layer and the outer main body layer. Between the inner main body layers, an external air passage is formed between the outer side of the middle support layer and the inner side of the outer main body layer, and an internal air passage is formed between the inner side of the middle support layer and the outer side of the inner main body layer. Multiple third mesh openings are formed through the inner and outer sides of the middle support layer, each connecting to the external and internal air passages. These third mesh openings are completely offset from and separated from multiple first mesh openings in the orthographic projection direction, and are also completely offset from and separated from multiple second mesh openings in the orthographic projection direction. A waterproof and breathable membrane layer is applied to the inner main body layer and completely covers the multiple second mesh openings. An antistatic coating is applied, molded, and fixed to the outer surface of the outer main body layer.

[0007] As a preferred embodiment, both the outer and inner main body layers are formed by stamping metal sheets. The periphery of the outer main body layer is bent inward to form a limiting ring, which presses against the periphery of the inner side of the inner main body layer.

[0008] As a preferred embodiment, the middle support layer is made of carbon fiber, and multiple inner support protrusions extend from the inner side of the middle support layer. These multiple inner support protrusions abut against the outer surface of the waterproof and breathable membrane layer, and multiple outer support protrusions extend from the outer side of the middle support layer. These multiple outer support protrusions abut against the inner surface of the outer main body layer.

[0009] As a preferred embodiment, a fixing ring is inlaid and fixed on the inner periphery of the mesh body, and the fixing ring is made of plastic.

[0010] As a preferred embodiment, a sealing ring is fixed on the inner end face of the fixing ring.

[0011] As a preferred embodiment, a fixing hole is provided on the inner end face of the fixing ring.

[0012] As a preferred embodiment, the waterproof and breathable membrane layer is attached to the outer surface of the inner main body layer and abuts against the middle support layer.

[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0014] This product's mesh body consists of an outer main body layer, an inner main body layer, a middle support layer, a waterproof and breathable membrane layer, and an antistatic coating. Its overall structure has good strength. The waterproof and breathable membrane layer provides excellent waterproof performance, effectively preventing external moisture from entering the speaker equipment through the mesh. The antistatic coating provides antistatic properties, preventing dust from adhering to the outer surface of the product, thus achieving dustproof functionality. Furthermore, the inclusion of recessed cavities and cable routing holes allows this product to be integrated with a control panel, effectively improving the integrated look of the speaker equipment and meeting user needs.

[0029] Please refer to Figure 1 and Figure 2 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a mesh body 10.

[0030] The mesh body 10 has an outer concave and inner convex shape, forming a cavity 101 on its outer surface for mounting a control panel. A wire-passing hole 102 is formed on the bottom surface of the cavity 101, extending through to the inner surface of the mesh body 10. In this embodiment, the cavity 101 is square, and the wire-passing hole 102 is round, located at the center of the cavity 101.

[0031] The mesh body 10 includes an outer main body layer 11, an inner main body layer 12, a middle support layer 13, a waterproof and breathable membrane layer 14, and an antistatic coating 15. The outer main body layer 11 has multiple first mesh openings 111 formed through its inner and outer surfaces. The inner main body layer 12 is located inside the outer main body layer 11, and its periphery is fixedly connected to the periphery of the outer main body layer 11. The inner and outer surfaces of the inner main body layer 12 have multiple second mesh openings 121 formed through its inner and outer surfaces. The middle support layer 13 is sandwiched between the outer main body layer 11 and the inner main body layer 12. An external air passage 103 is formed between the outer side of the middle support layer 13 and the inner side of the outer main body layer 11. An inner air passage 104 is formed between the inner side and the outer side of the inner main body layer 12, and a plurality of third mesh holes 131 are formed through the inner and outer sides of the middle support layer 13. The plurality of third mesh holes 131 are all connected between the outer air passage 103 and the inner air passage 104. The plurality of third mesh holes 131 are completely misaligned and separated from the plurality of first mesh holes 111 in the orthographic projection direction, and the plurality of third mesh holes 131 are completely misaligned and separated from the plurality of second mesh holes 121 in the orthographic projection direction. The waterproof and breathable membrane layer 14 is attached to the inner main body layer 12 and completely covers the plurality of second mesh holes 21. The antistatic coating 15 is coated and fixed on the outer side of the outer main body layer 11.

[0032] In this embodiment, both the outer main body layer 11 and the inner main body layer 12 are formed by stamping metal sheets. The periphery of the outer main body layer 11 is bent inward to form a limiting ring 112, which presses against the periphery of the inner side surface of the inner main body layer 12, thereby fixing the outer main body layer 11 and the inner main body layer 12 together. The plurality of first mesh holes 111 and the plurality of second mesh holes 121 are all circular holes, but they can also be through holes of other shapes, without limitation.

[0033] The waterproof and breathable membrane layer 14 is attached to the outer surface of the inner main body layer 12 and abuts against the middle support layer 13. Of course, the waterproof and breathable membrane layer 14 can also be attached to the inner surface of the inner main body layer 12, without limitation. Furthermore, the middle support layer 13 is made of carbon fiber, and multiple inner support protrusions 132 extend from the inner side of the middle support layer 13. The multiple inner support protrusions 132 are arranged at intervals and abut against the outer surface of the waterproof and breathable membrane layer 14 to better form the inner air channel 104. Multiple outer support protrusions 133 extend from the outer side of the middle support layer 13. The multiple outer support protrusions 133 are arranged at intervals and abut against the inner surface of the outer main body layer 11 to better form the outer air channel 103.

[0034] Furthermore, a fixing ring 20, made of plastic, is inlaid and fixed to the inner periphery of the mesh body 10. In this embodiment, a sealing ring 30 is fixed to the inner end face of the fixing ring 20 for waterproof sealing installation with the speaker device. Additionally, a fixing hole 21, which is a screw hole, is provided on the inner end face of the fixing ring 20 for fixed connection with the speaker device.

[0035] When in use, this product is installed on the speaker equipment and covers the speaker. The control panel of the speaker equipment is embedded in the cavity 101 and fixed. At the same time, the connecting wire of the control panel passes through the wire hole 102 and extends into the speaker equipment to connect with the control system inside the speaker equipment. A waterproof ring is sandwiched between the connecting wire and the wire hole 102 to achieve waterproof installation.

[0036] During operation, the sound generated by the speaker propagates outward sequentially through the second mesh 121, the waterproof and breathable membrane layer 14, the inner air channel 104, the third mesh 131, the outer air channel 103, and the first mesh 111. External moisture cannot penetrate the waterproof and breathable membrane layer 14 to enter the speaker enclosure, thus achieving waterproofing. Simultaneously, the antistatic coating 15 provides antistatic protection, preventing dust from adhering to the outer surface of the product, thus achieving dustproofing. Furthermore, because the first mesh 111 and the second mesh 121 are separated by the middle support layer 13, they are not directly connected, effectively protecting the waterproof and breathable membrane layer 14 and preventing sharp objects from piercing it from the outside, thus ensuring long-lasting and effective waterproofing.

[0037] The key design features of this invention are as follows: the mesh body of this product is composed of an outer main body layer, an inner main body layer, a middle support layer, a waterproof and breathable membrane layer, and an antistatic coating. Its overall structure has good strength. The waterproof and breathable membrane layer provides excellent waterproof performance, effectively preventing external moisture from entering the speaker equipment through the mesh. The antistatic coating provides antistatic properties, preventing dust from adhering to the outer surface of the product, thus achieving dustproof functionality. Furthermore, the inclusion of recessed cavities and wire holes allows the product to be integrated with a control panel, effectively improving the integrated effect of the speaker equipment and meeting user needs.

[0038] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
