[0002] With the advancement of science and technology, more and more electronic products are shifting from physical transmission media to wireless transmission. This includes the shift from wired headphones to Bluetooth headsets. Since headphones offer the same functionality as telephone handsets, but with hands-free operation, they have many applications, including in call centers and other call-intensive jobs, and for anyone who prefers to talk hands-free. However, traditional wired headphones remain popular due to their superior interference immunity and low latency compared to wireless transmission, providing clearer and lossless sound quality that meets the needs of most consumers. Headphone cable quality often impacts product performance. To ensure that wired headphones remain competitive in the market and meet the high-fidelity listening demands of more music lovers, improvements to traditional headphone cables are needed. This paper proposes a novel solution that not only improves audio transmission performance and interference immunity, but also enhances damage resistance, thereby increasing durability and extending the lifespan of wired headphones.

From the content disclosed in the two retrieved patent documents, it can be seen that each provides a headphone cable that meets the use requirements from different perspectives. In order to provide clearer and lossless sound quality, while meeting the audio transmission performance and anti-interference capabilities, in order to improve its damage resistance and enhance its tensile strength to extend its service life, a headphone cable different from the prior art is provided to meet the use needs of most consumers. Utility Model Content

[0004] The technical problem to be solved by the present invention is to address the problems existing in the background technology, thereby providing a high-fidelity, tensile-resistant and wear-resistant headphone cable. On the premise of meeting the audio transmission performance and anti-interference ability, it also has the advantages of high tensile strength, wear resistance, long service life, and good use effect, so as to meet the usage needs of most consumers. Specifically, it is a high-fidelity, tensile-resistant and wear-resistant headphone cable.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a high-fidelity, tensile-resistant and wear-resistant headphone cable, comprising a wire core, the wire core comprising multiple conductors and multiple reinforcing ropes, and a tape layer arranged on the outside of the wire core, an outer shielding layer is provided on the outside of the tape layer, an outer insulating layer is provided on the outer shielding layer, and a braided sheath layer is provided on the outer insulating layer, and a filling layer is filled between the wire cores in the tape layer.

[0006] Furthermore, a high-fidelity, tensile-resistant, and wear-resistant headphone cable as described in the utility model is used, wherein five conductors are provided and six reinforcing ropes are provided, a reinforcing rope is provided in the center of the wire core, and the five conductors are evenly arranged in a ring shape on the outside of the reinforcing rope located in the middle, and a reinforcing rope is provided on each of the two adjacent conductors, and the five reinforcing ropes are evenly arranged in a ring shape on the outside of the reinforcing rope located in the middle.

[0007] Furthermore, a high-fidelity, tensile-resistant, and wear-resistant headphone cable as described in the utility model is used, wherein the conductor includes a copper core and an inner insulating layer extruded on the copper core, and an inner shielding layer is provided on the inner insulating layer; wherein the copper core is a Category VI tinned copper conductor, the inner insulating layer is extruded with EPDM rubber, and the inner shielding layer is woven with tinned copper wire, and its braiding density is controlled to be above 85%.

[0008] Furthermore, the high-fidelity, tensile-resistant, and wear-resistant headphone cable described in the utility model is adopted, and the reinforcement rope is formed by twisting polyimide fibers.

[0009] Furthermore, the high-fidelity, tensile-resistant, and wear-resistant headphone cable described in the utility model is used, and the filling layer is filled with cotton fibers.

[0010] Furthermore, the high-fidelity, tensile-resistant, and wear-resistant headphone cable described in the utility model is adopted, and the wrapping layer is formed by wrapping an aluminum foil composite film.

[0011] Furthermore, the high-fidelity, tensile-resistant, and wear-resistant headphone cable described in the utility model is adopted, and the outer shielding layer is woven with tinned copper wire, and its braiding density is controlled to be above 85%.

[0012] Furthermore, the high-fidelity, tensile-resistant, and wear-resistant headphone cable of the present invention is used, wherein the outer insulating layer is formed by extruding a polyurethane insulating material.

[0013] Furthermore, the high-fidelity, tensile-resistant, and wear-resistant headphone cable described in the utility model is adopted, and the braided sheath layer is a nylon braided sheath structure.

[0014] The high-fidelity, tensile-resistant, and wear-resistant headphone cable described in the utility model adopts a five-core Category VI tinned copper conductor in the cable core. While maintaining flexibility, different transmission configurations can be set according to different needs. At the same time, each conductor is first insulated and shielded, and then a secondary insulation and shielding treatment is performed outside the cable core. This effectively isolates signal interference between conductors. Furthermore, because the tape layer is wrapped with an aluminum foil composite film, and the outer shielding layer is woven with tinned copper wire, this effectively isolates external signal interference, prevents noise from affecting the listening experience and sound quality, and achieves high fidelity.

[0015] Secondly, a reinforcement rope is installed in the center of the filling layer filled with cotton fiber and between two adjacent conductors. The reinforcement rope is made of twisted polyimide fiber. Since polyimide fiber is a new type of specialty fiber, which refers to fibers containing aromatic imide rings in the molecular chain, polyimide fiber has the advantages of high strength, high modulus, high temperature resistance, flame retardancy, radiation protection, and chemical corrosion resistance. The reinforcement rope is made of six twisted polyimide fibers. This can ensure uniform load distribution, enhance cross-sectional stability, and prevent wire breakage caused by excessive extension, thereby enhancing its tensile performance.

[0016] Finally, since there is a braided sheath layer outside the outer insulation layer, the outer insulation layer is made of extruded polyurethane insulation material, and the braided sheath layer is a nylon braided sheath structure. Since both polyurethane and nylon have good flexibility and durability, and polyurethane insulation has good sealing performance, it ensures that the copper wire and conductor are not oxidized, and the protection of the nylon braided sheath makes its application range wider and its service life longer.

[0017] It can be seen that the headphone cable described in the present invention adopts a double-layer insulation and double-layer shielding structure, which enhances the shielding effect, improves the anti-interference ability of the headphone cable, and achieves the purpose of high fidelity. The six reinforcing ropes are provided to enhance its tensile strength. On the premise of meeting the audio transmission performance and anti-interference ability, it also has the advantages of high tensile strength, wear resistance, extended service life of the headphone cable, and good use effect. It can meet the use needs of most consumers. Its overall structure is simple and the design is reasonable, and it is worthy of promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS
