TECHNICAL FIELD

[0001] The utility model relates to signal transmission wire technical field, concretely is a kind of magnetic interference-resistant audio cable. BACKGROUND

[0002] With the continuous progress of science and technology and the increasing demand of society for high-quality audio transmission, the importance of anti-interference audio cable is increasingly prominent. In modern audio transmission systems, especially in the fields of high-fidelity sound, professional recording studio, stage performance, broadcast television and security monitoring, the cable not only needs to bear the task of stable signal transmission, but also needs to have excellent anti-interference ability to ensure the purity and clarity of audio signals.

[0003] During the transmission process of traditional audio cable, it is often susceptible to various electromagnetic interferences from external environment, such as radio waves, power line radiation, and mutual interference between devices. These interferences not only cause distortion of audio signals and increase of noise, but also may cause signal attenuation and transmission delay, which seriously affect the sound quality and listening experience of audio. At the same time, the storage problem of audio cable is also a common trouble encountered by users during use. Traditional audio cable lacks convenient storage method and is easy to entangle and knot, which not only is inconvenient to carry, but also may be damaged during the process of arranging. Therefore, in order to solve this problem, the inventor proposes a magnetic interference-resistant audio cable. SUMMARY

[0004] In view of the deficiencies in the above-mentioned technology, the utility model provides a magnetic interference-resistant audio cable.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a magnetic interference-resistant audio cable, comprising a core and a first conductive PE, the first conductive PE is wrapped around the outer peripheral wall of the core, further comprising a foamed insulation layer, a second conductive PE, a composite braided layer and a magnetic attraction layer, the foamed insulation layer is arranged on the outer peripheral wall of the first conductive PE, the second conductive PE is arranged on the outer peripheral wall of the foamed insulation layer, the composite braided layer is arranged on the outer peripheral wall of the second conductive PE, and the magnetic attraction layer is arranged on the outer peripheral wall of the composite braided layer, for storing the audio cable.

[0006] As a further elaboration, the magnetic attraction layer extends outwardly and is provided with a protective sleeve, and the protective sleeve (which can be a braided layer or a plastic layer) is wrapped around the outer peripheral wall of the magnetic attraction layer.

[0007] As a further elaboration, the composite braided layer is made of high-elastic wire and copper wire, which is woven along an "8" shaped curve track in a circular motion.

[0008] As a further explanation, the first conductive PE and the second conductive PE are made of highly conductive polyethylene material.

[0009] As a further illustration, the protective cover is made of PVC, TPU or TPE.

[0010] As a further illustration, the foamed insulation layer is made of a low-density, high-elasticity foamed material.

[0011] To sum up, the utility model has the following beneficial effects: the utility model is a magnetic anti-interference audio cable, which adopts a double-layer conductive PE (first conductive PE and second conductive PE) design, combined with the multi-layer shielding effect achieved by the composite braided layer, effectively isolates external electromagnetic interference, and at the same time prevents the leakage of the signal within the line, ensuring the purity and transmission stability of the audio signal. The composite braided layer is woven by high-elastic wire and copper wire in an "8"-shaped curved track, which not only provides strong tensile strength and wear resistance, but also further improves the flexibility and durability of the audio cable, effectively preventing the cable from being damaged by bending or stretching during use.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figures 1-4The utility model discloses a kind of magnetic interference-resistant audio frequency lines, including wire core 1 and first conductive PE 11, the first conductive PE 11 is wrapped in the outer peripheral wall of wire core 1, further including foamed insulation layer 12, second conductive PE 13, composite braided layer 14 and magnetic attraction layer 2, the foamed insulation layer 12 is set on the outer peripheral wall of first conductive PE 11, the second conductive PE 13 is set on the outer peripheral wall of foamed insulation layer 12, the composite braided layer 14 is set on the outer peripheral wall of second conductive PE 13, the magnetic attraction layer 2 is set on the outer peripheral wall of composite braided layer 14.

[0018] Specifically, audio signals are transmitted through the central wire core 1. The wire core 1 serves as the main carrier of the signals, responsible for transmitting the audio signals from one end to the other. The first conductive PE 11 wrapped around the outer peripheral wall of the wire core 1 plays a preliminary shielding role. Since the first conductive PE 11 has high conductivity, it can effectively isolate the external electromagnetic field from interfering with the audio signals transmitted in the wire core 1, while preventing signal leakage, ensuring the purity and stability of the signal transmission.

[0019] On the outer layer of the first conductive PE 11, there is a foamed insulation layer 12. This layer not only provides electrical insulation to prevent short circuits or electrical leakage during signal transmission, but also absorbs and buffers external physical impacts to some extent due to its low density and high elasticity, protecting the internal wire core 1 and conductive PE from damage.

[0020] The outer peripheral wall of the foamed insulation layer 12 is covered with a second conductive PE 13. The second conductive PE 13 is tightly connected with the foamed insulation layer 12, further enhancing the shielding effect. Together with the first conductive PE 11, it forms a double-layer shielding structure, more effectively isolating external electromagnetic interference and ensuring high-quality transmission of audio signals.

[0021] The outer peripheral wall of the composite braided layer 14 is provided with a magnetic attraction layer 2, which is attached to the outer peripheral wall of the composite braided layer 14 for storing the audio frequency line. The magnetic attraction layer 2 extends outwardly and is provided with a protective sleeve 3, which (the protective sleeve 3 can be a braided layer or a plastic layer) wraps around the outer peripheral wall of the magnetic attraction layer 2.

[0022] Specifically, the magnetic attraction layer 2 allows the audio frequency line to be easily fixed and stored when not in use, making it convenient to carry. The protective sleeve 3 as the outermost protective layer further enhances the impact resistance, scratch resistance and corrosion resistance of the audio frequency line, ensuring its long service life.

[0023] The composite braided layer 14 is braided by high elastic line and copper wire along the "8" shaped curve track, the first conductive PE 11 and the second conductive PE 13 are made of high conductive polyethylene material, the protective sleeve 3 is made of PVC, TPU or TPE material, and the foamed insulation layer 12 is made of low density and high elasticity foamed material.

[0024] Specifically, the composite braided layer 14 is braided by high elastic line and copper wire along the "8" shaped curve track, and has very high tensile strength and wear resistance. It can not only protect the internal core 1 and the shielding layer from physical damage from the outside, but also can enhance the flexibility and durability of the audio cable to a certain extent.

[0025] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application.
