Description

Technical Field

[0001] This utility model relates to the field of automotive fabric technology, specifically to a 3D-MESH fabric for car audio systems. Background Technology

[0002] The passenger compartment of a car is where the car and its occupants interact frequently. Occupants interact with the interior components of the passenger compartment through sight, hearing, touch, and smell.

[0003] Traditional car audio systems have many shortcomings in terms of sound propagation, structural stability, anti-interference ability, and compatibility with interior design. Ordinary fabric materials are difficult to effectively suppress reflection and distortion during sound propagation, resulting in muddy sound quality. Vibrations generated during vehicle operation can easily loosen audio components, causing resonance noise and affecting the listening experience. At the same time, external electromagnetic interference can also interfere with audio signal transmission and reduce the purity of sound quality. Utility Model Content

[0004] Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, the present invention provides a 3D-MESH fabric for car audio, which can effectively solve the problems in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a 3D-MESH fabric for car audio, including a bottom cover, a top cover, and a fabric material disposed between the two. The fabric material includes a MESH layer and a metal mesh fabric, which are bonded and fixed together by PA mesh hot melt adhesive. The metal mesh fabric includes memory foam fabric, metal mesh, and carbon fiber fabric. The upper and lower ends of the metal mesh are bonded and fixed to the memory foam fabric and carbon fiber fabric by adhesive.

[0006] Furthermore, both the top cover and the bottom cover have through slots in the middle, and the top of both the top cover and the bottom cover have concave structures. The outer edge of the top cover is rolled inward toward the bottom, and the internal dimensions of the rolled part are the same as the thickness of the bottom cover.

[0007] Furthermore, the MESH layer is a three-dimensional mesh fabric, and its material is woven from polyester single-hole filaments and ordinary polyester fibers.

[0008] Furthermore, the metal mesh consists of multiple sets of zigzag metal wires as warp and spirally wound metal wires as weft, with two adjacent warp strands wound and connected on both sides of the weft.

[0009] Furthermore, both sides of the fabric material are curled inwards towards the bottom.

[0010] The technical solution provided by this utility model has the following advantages compared with the known public technology: This invention features a combination structure of a top cover, fabric material, and bottom cover. Users can cover the outside of the speaker with this combination structure. The top cover and bottom cover not only serve to fix the internal fabric material, but also improve the sound effect and expand the range of influence through their concave structure.

[0011] In this device, the fabric material is composed of three components. The outer mesh layer, with its unique porous structure and excellent breathability, allows sound to propagate more naturally and smoothly, reducing sound reflection and distortion. This provides passengers with a purer, clearer music experience and can, to some extent, suppress resonance during audio system operation. Its special material and structure absorb and disperse vibrational energy, preventing noise caused by resonance and improving sound quality stability. The addition of a metal mesh fabric provides better protection against damage to internal audio components from external objects. Its electromagnetic shielding properties help reduce external electromagnetic interference, improving the audio system's anti-interference capabilities and ensuring the purity of the sound signal. Memory foam fabric improves the fit and stability of the audio system installation, reducing speaker vibration and friction noise caused by vehicle bumps. Finally, carbon fiber fabric enhances the structural stability of the audio system, reducing deformation caused by vibration and helping to maintain accurate sound quality. Its good thermal conductivity also helps dissipate heat, improving system reliability and lifespan. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0017] Example: A 3D-MESH fabric for car audio systems, see attached diagram. Figure 1 - Appendix Figure 7 The system includes a bottom cover 2, a top cover 1, and a fabric material 3 disposed between the two. The fabric material 3 includes a MESH layer 31 and a metal mesh fabric 32, which are bonded and fixed together by PA mesh hot melt adhesive. The metal mesh fabric 32 includes a memory foam fabric 321, a metal mesh 322, and a carbon fiber fabric 323. The upper and lower ends of the metal mesh 322 are bonded and fixed to the memory foam fabric 321 and the carbon fiber fabric 323. The memory foam fabric can improve the fit and stability of the speaker installation and reduce speaker shaking and friction noise caused by vehicle bumps.

[0018] Both the top cover 1 and the bottom cover 2 have through slots in the middle, and the tops of both the top cover 1 and the bottom cover 2 are concave structures. The outer edge of the top cover 1 is rolled inwards towards the bottom, and the internal dimensions of the rolled part are the same as the thickness of the bottom cover 2. The combination structure of the top cover 1, fabric material 3, and bottom cover 2 allows the user to cover the outside of the speaker. The top cover 1 and the bottom cover 2 not only serve to fix the internal fabric material 3, but also improve the sound effect and expand the range of influence through the concave structure.

[0019] The MESH layer 31 is a three-dimensional mesh fabric woven from single-hole polyester filaments and ordinary polyester fibers. The fabric material is composed of three materials. The outer MESH layer 31 has a unique porous structure and good breathability, allowing sound to propagate more naturally and smoothly, reducing sound reflection and distortion. This allows passengers to enjoy purer, clearer music and can, to some extent, suppress resonance phenomena generated during audio system operation. Through its special material and structure, it absorbs and disperses vibrational energy, avoiding noise caused by resonance and improving the stability of sound quality. The metal mesh 322 consists of multiple sets of zigzag metal wires as warp and spirally wound metal wires as weft, with the weft wires wound and connected to adjacent warp strands on both sides. The inclusion of the metal mesh 322 fabric material provides better protection, preventing damage to the internal components of the speaker from external objects. Its electromagnetic shielding properties help reduce external electromagnetic interference, improve the speaker's anti-interference ability, and ensure the purity of the sound signal.

[0020] Both sides of the fabric material 3 are curled inwards towards the bottom.
