Description

Technical Field

[0001] This utility model relates to the field of audio cables, and more particularly to a highly protective audio cable. Background Technology

[0002] A high-protection speaker cable is an audio transmission cable that can transmit signals with high quality during audio signal transmission and has multiple protection functions to cope with complex usage environments. With the continuous advancement of audio technology, the application of high-fidelity audio systems is becoming more and more widespread. For example, in the field of home theater, from traditional stereo systems to today's multi-channel surround sound systems, the requirements for the quality of audio signal transmission are increasing day by day. As a key component for audio signal transmission, speaker cables need to be able to accurately and losslessly transmit rich audio signals from low frequencies to high frequencies.

[0003] Most existing speaker wires use single or multiple insulation layers to provide simple protection. In today's environment with a high density of electronic devices, electromagnetic radiation from devices such as mobile phones, wireless routers, and televisions can easily penetrate the insulation layer and interfere with audio signals, resulting in noise or distortion in the audio. During use, speaker wires may be squeezed by furniture or bent excessively at corners. Without a good protective structure, the internal conductors may be damaged, affecting the performance and lifespan of the speaker wire.

[0004] Therefore, given that existing speaker wires rely on simple single or multiple insulation layers for protection, electromagnetic radiation from electronic devices such as mobile phones, routers, and televisions can easily penetrate the insulation layer in environments with a high density of electronic devices, interfering with audio signals and causing noise or distortion, and that speaker wires may be subjected to excessive pressure from furniture or bending at corners during use, the internal conductors can be easily damaged if the protection is inadequate, affecting performance and lifespan, a highly protective speaker wire can be designed to achieve multiple layers of comprehensive protection through a primary insulation tube, a secondary insulation tube, a metal braided shielding tube, an aluminum foil shielding layer, and a nylon sheath. Utility Model Content

[0005] To overcome the problem that existing speaker wires rely on simple single or multiple insulation layers for protection, electromagnetic radiation from electronic devices such as mobile phones, routers, and televisions can easily penetrate the insulation layer in environments with dense electronic devices, interfering with audio signals and causing noise or distortion. During use, speaker wires may be squeezed by furniture or bent excessively at corners. If the protection is inadequate, the internal conductors are easily damaged, affecting performance and lifespan.

[0006] The technical solution of this utility model is as follows: a high-protection audio cable, including a main oxygen-free copper wire, a connecting platform, an audio connector plug, and a load-bearing outer shell; both ends of the main oxygen-free copper wire are equipped with connecting platforms for quick replacement of the audio connector plug, and the top of each connecting platform is equipped with an audio connector plug for connecting and transmitting audio signals; the main oxygen-free copper wire is externally fitted with a load-bearing outer shell to resist compression; the main oxygen-free copper wire and the auxiliary oxygen-free copper wire are arranged in multiple sets of vertically wound loops; the outer ends of the main oxygen-free copper wire and the auxiliary oxygen-free copper wire are fitted with a primary insulating tube, and the primary insulating tube is externally fitted with a secondary insulating tube.

[0007] Preferably, both ends of the main oxygen-free copper wire are equipped with connectors, which greatly facilitates the quick replacement of audio connector plugs. In the actual construction or use of audio systems, it is often necessary to replace different types of plugs to adapt to different audio equipment. The main oxygen-free copper wire and the auxiliary oxygen-free copper wire are arranged in multiple vertical surrounds. The main oxygen-free copper wire, as the main signal transmission carrier, has the excellent conductivity of high-purity oxygen-free copper and can effectively transmit audio signals. The auxiliary oxygen-free copper wire plays an auxiliary and optimization role in the signal transmission process. The multiple vertical surrounds design makes the magnetic field distribution more uniform. The electromagnetic coupling effect between adjacent copper wires is effectively utilized. The main oxygen-free copper wire and the auxiliary oxygen-free copper wire are fitted with a primary insulating tube at their outer ends. A secondary insulating tube is then fitted outside the primary insulating tube, forming a double-layer insulation protection system. The primary insulating tube is directly wrapped around the copper wire. It is made of a material with good insulation properties and flexibility, which can play a basic role in insulating the copper wire. It is tightly attached to the surface of the copper wire, effectively preventing short circuits caused by accidental contact between the copper wires. It also avoids contact between the copper wire and any conductive objects that may exist in the outside world, ensuring the independence and stability of signal transmission.

[0008] Preferably, a metal braided shielding tube is fitted over the outer end of the secondary insulating tube, and an aluminum foil shielding layer is fitted over the outer end of the metal braided shielding tube.

[0009] Preferably, the outer end of the aluminum foil shielding layer is fitted with a nylon sheath, and the surface of the nylon sheath is coated with a fire-retardant coating.

[0010] Preferably, the rear end of the connecting platform is provided with a contact block mounting groove, and a gold-plated contact block is installed in the contact block mounting groove at the rear end of the connecting platform. The gold-plated contact block is hollow.

[0011] Preferably, the front end of the connector is provided with a plug mounting slot, a sealing ring is installed inside the plug mounting slot, and a plug mounting platform is installed at the center of the plug mounting slot.

[0012] Preferably, the bottom of the audio connector has a connection hole for connecting the connector mounting plate, and the surface of the audio connector is nickel-plated.

[0013] As a preferred embodiment, multiple sets of fixing plates are linearly installed on both sides of the load-bearing outer shell, and threaded fixing holes are drilled through the center of the fixing plates.

[0014] The beneficial effects of this utility model are:

[0015] 1. The main and auxiliary oxygen-free copper wires are arranged in multiple vertical loops. Compared with the traditional single-strand or simply twisted copper wire structure, this effectively reduces electromagnetic interference and optimizes signal transmission. This structure makes the magnetic field distribution more uniform, reducing signal loss and distortion during transmission and ensuring high fidelity of audio signals. The combination of metal braided shielding tube and aluminum foil shielding layer forms a highly efficient full-band electromagnetic shielding system. In today's environments with dense electronic devices, such as home theater systems surrounded by multiple electromagnetic radiation sources such as mobile phones, wireless routers, and televisions, this shielding system can effectively block external electromagnetic interference compared to existing systems that are easily... This invention ensures that the audio signal is not interfered with by electromagnetic radiation penetrating the insulation layer, avoiding noise or distortion in the audio. The nylon sheath and the fire-retardant coating on the surface provide comprehensive external protection for the audio cable. The nylon sheath has high wear resistance and tensile strength. In daily use, when the audio cable is squeezed by furniture or bent excessively at a corner, it can effectively protect the internal structure and prevent conductor damage. In case of fire or other emergencies, the fire-retardant coating can quickly expand to form a heat insulation layer, protecting the audio cable from flames and high temperatures, improving the audio cable's survivability in special environments and extending its service life.

In the actual construction or use of audio systems, it is often necessary to replace different types of plugs to adapt to different audio equipment. The main oxygen-free copper wire 1 and the auxiliary oxygen-free copper wire 102 are arranged in multiple vertical surround configurations. The main oxygen-free copper wire 1, as the primary signal transmission carrier, possesses the excellent conductivity of high-purity oxygen-free copper, effectively transmitting audio signals. The auxiliary oxygen-free copper wire 102 plays an auxiliary and optimizing role in signal transmission. The multiple vertical surround design makes the magnetic field distribution more uniform, and the electromagnetic coupling effect between adjacent copper wires is effectively utilized. The outer ends of the copper wire 1 and the auxiliary oxygen-free copper wire 102 are fitted with a primary insulating tube 103, and a secondary insulating tube 104 is fitted outside the primary insulating tube 103, forming a double-layer insulation protection system. The primary insulating tube 103 is directly wrapped around the copper wire. It is made of a material with good insulation properties and flexibility, which can play a basic role in insulating the copper wire. It is tightly attached to the surface of the copper wire, effectively preventing short circuits caused by accidental contact between the copper wires. It also avoids contact between the copper wire and any conductive objects that may exist in the outside world, ensuring the independence and stability of signal transmission.

[0023] Please see Figure 2In this embodiment, a metal braided shielding tube 105 is fitted over the outer end of the secondary insulating tube 104, and an aluminum foil shielding layer 106 is fitted over the outer end of the metal braided shielding tube 105. The metal braided shielding tube 105 is fitted over the outer end of the secondary insulating tube 104, and its metal braided structure forms a continuous conductive network. This structure has excellent shielding ability against external electromagnetic interference. The aluminum foil shielding layer 106 is located at the outer end of the metal braided shielding tube 105, and it has excellent shielding effect against high-frequency electromagnetic interference. The aluminum foil has good conductivity and continuity, and can reflect and absorb high-frequency electromagnetic waves. A nylon sheath 101 is fitted over the outer end of the aluminum foil shielding layer 106. The surface of the nylon sheath 101 is coated with a fire-retardant coating. The nylon sheath 101 is fitted over the aluminum foil shielding layer 106, providing strong physical protection for the speaker wire. The nylon material has high wear resistance. During the daily use, installation and movement of the speaker wire, even if it is frequently rubbed against rough surfaces or other objects, it can effectively protect the internal shielding layer, insulation layer and copper wire from wear.

[0024] Please see Figures 3-4 In this embodiment, the rear end of the connecting platform 2 is provided with a contact block mounting groove 205, and a gold-plated contact block 201 is installed in the contact block mounting groove 205 at the rear end of the connecting platform 2. The gold-plated contact block 201 is hollow, which provides convenient space for the conductor inside the speaker wire. During the installation process, the conductor of the speaker wire can be directly inserted into the hollow part, and then electrically connected to the gold-plated contact block 201 through a suitable connection method. This design simplifies the connection process, improves production efficiency, and also makes the connection more firm and stable, reducing signal problems caused by improper connection. The front end of the connecting platform 2 is provided with a plug mounting groove 204, and a sealing ring 202 is installed inside the plug mounting groove 204. A plug mounting platform 203 is installed at the center of the plug mounting groove 204. Installing the sealing ring 202 in the plug mounting groove 204 can effectively prevent dust, debris and other small particulate impurities from entering the interior of the connecting platform 2.

[0025] Please see Figures 3-4In this embodiment, the surface of the audio connector 3 is nickel-plated, which provides excellent corrosion and oxidation resistance. Multiple sets of fixing plates 401 are linearly installed on both sides of the load-bearing housing 4. A threaded fixing hole 402 is opened through the center of the fixing plate 401. The stable installation structure formed by the multiple sets of fixing plates 401 and the threaded fixing hole 402 enables the load-bearing housing 4 to provide reliable physical protection for the audio wires. By fixing the load-bearing housing 4 in a suitable position using the fixing plates 401 and the threaded fixing hole 402, the audio wires can be neatly routed. In large-scale audio system installations, such as theaters and concert venues, a large number of audio wires can easily become messy if not effectively managed. The load-bearing housing 4 can be installed along a predetermined route to store the audio wires, making the wiring more standardized and aesthetically pleasing, and also facilitating later maintenance and repair.

[0026] During operation, multiple sets of fixing plates 401 are linearly installed on both sides of the load-bearing outer shell 4, and threaded fixing holes 402 are drilled through the center of the fixing plates 401 for installation and fixing. When installing speaker wires, bolts or other fasteners can be passed through the threaded fixing holes 402 to fix the load-bearing outer shell 4 in a suitable position, such as a wall, bracket, or other fixed structure. This fixing method can make the speaker wires neat and orderly arranged, avoiding messiness. At the same time, when it is necessary to adjust the position of the speaker wires or perform maintenance, it can be easily disassembled and reinstalled. In the fixed state, the load-bearing outer shell 4 can better perform its protective function, maintain the stability of the speaker wires, and reduce the impact of shaking. This design minimizes the risk of damage from movement or displacement. Throughout its use, the speaker cable operates efficiently and stably in complex environments, ensuring efficient signal transmission, protection, and secure installation. The main oxygen-free copper wire 1 serves as the primary audio signal transmission path, and its multiple vertically wound structures with the auxiliary oxygen-free copper wires 102 effectively reduce electromagnetic interference. During transmission, the audio signal travels from the main oxygen-free copper wire 1 to the connector 2. The hollow gold-plated contact block 201, located in the contact block mounting groove 205 at the rear of the connector 2, receives the signal. Thanks to its excellent conductivity and oxidation resistance, the gold-plated contact block 201 continues to transmit the signal with almost no loss. The hollow structure not only facilitates connection with the main oxygen-free copper wire 1 but also buffers the impact of external forces on the connection point, ensuring connection stability. The signal reaches the plug mounting groove 204 area at the front of the connector 2. Here, the sealing ring 202 prevents dust, moisture, and other impurities from affecting the electrical connection. The plug mounting platform 203 at the center of the plug mounting groove 204 tightly engages with the connection hole at the bottom of the speaker connector plug 3, achieving a stable connection and precise positioning between the plug and the connector 2. The nickel plating on the surface of the audio connector 3 ensures good conductivity and wear resistance during long-term plugging and unplugging, ensuring that the signal is accurately transmitted to the audio equipment through the audio connector 3.

[0027] Through the above steps, connectors 2 are installed at both ends of the main oxygen-free copper wire 1, which greatly facilitates the quick replacement of audio connector plugs 3. In the actual construction or use of audio systems, it is often necessary to replace different types of plugs to adapt to different audio equipment. The main oxygen-free copper wire 1 and the auxiliary oxygen-free copper wire 102 are arranged in multiple vertical surrounds. The main oxygen-free copper wire 1, as the main signal transmission carrier, has the excellent conductivity of high-purity oxygen-free copper and can effectively transmit audio signals. The auxiliary oxygen-free copper wire 102 plays an auxiliary and optimization role in the signal transmission process. The design of multiple vertical surrounds makes the magnetic field distribution more uniform. The electromagnetic coupling effect between adjacent copper wires is effectively utilized. The outer ends of the main oxygen-free copper wire 1 and the auxiliary oxygen-free copper wire 102 are fitted with a primary insulating tube 103, and a secondary insulating tube 104 is fitted outside the primary insulating tube 103, forming a double-layer insulation protection system. The primary insulating tube 103 is directly wrapped around the copper wire. It is made of a material with good insulation performance and flexibility, which can play a basic role in insulation of the copper wire. It is tightly attached to the surface of the copper wire, effectively preventing short circuits caused by accidental contact between copper wires. It also avoids contact between the copper wire and any conductive objects that may exist in the outside world, ensuring the independence and stability of signal transmission.
