Description

Technical Field

[0001] This utility model relates to the field of audio cables, and in particular to a high-fidelity audio cable. Background Technology

[0002] Traditional audio cables, whether positive or negative, consist of one or several thin copper wires. This uniform structure leads to high distortion, poor musicality, insufficient clarity, and unclear bass and treble separation. To address this, the inventor designed and patented an audio cable (patent publication number CN206506123U) that transmits better sound signals with higher fidelity. However, sound is transmitted via constantly changing electrical signals. Since audio cables contain multiple wire bundles, the constantly changing current signals generate a magnetic field around the bundles. This results in interference between the magnetic fields generated by the power and signal lines, causing sound signal distortion. Current audio cables cannot solve this problem. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide an audio cable that delivers higher fidelity audio signals, thereby increasing the quality of the transmitted audio signal.

[0004] The technical solution adopted by this utility model to solve the problem is: a high-fidelity audio cable, comprising a cable body and two connectors disposed at both ends of the cable body.

[0005] The cable includes a positive power supply line, a negative power supply line, a positive signal line, and a negative signal line. Both ends of the cable are arranged in the order of positive power supply line, negative signal line, positive signal line, and negative power supply line and are respectively connected to two connectors.

[0006] The positive signal line is composed of segments A1, A2, A3, and A4 connected sequentially, and the negative signal line is composed of segments B1, B2, B3, and B4 connected sequentially. Segments A1 and B1 are single-strand thick copper wires; segments A2 and B2 are composed of several single copper wires without an insulating layer between them; segment A3 is a positive coil formed by winding a single thick copper wire. This positive coil is divided into a first positive coil segment and a second positive coil segment, which are interconnected and rotate in the same direction. A first intermediate separating layer is formed between the first and second positive coil segments. The front end of the first positive coil segment is connected to segment A2, and the rear end of the second positive coil segment is connected to segment A4. Segment B3 is a negative coil formed by winding a single thick copper wire. The negative coil is divided into a first negative coil segment and a second negative coil segment that are connected to each other and rotate in the same direction. A second intermediate separating layer is formed between the first negative coil segment and the second negative coil segment. The front end of the first negative coil segment is connected to segment B2, and the rear end of the second negative coil segment is connected to segment B4. The positive and negative coils are arranged in parallel and are insulated from each other. The positive and negative coils rotate in the same direction. Segment A4 and segment B4 are composed of several single copper wires with insulating layers between them.

[0007] Both the positive and negative power supply lines are composed of several copper wires. The positive power supply line includes a positive winding segment in the middle, with its front end located at the front end of the first negative coil segment. The positive winding segment winds around the outer periphery of the first negative coil segment to the inner side of the top of the first negative coil segment and then extends downward to the second intermediate separator layer, extending along the second intermediate separator layer towards the bottom of the negative coil to form a U-shape. The negative power supply line includes a negative winding segment in the middle, with its front end located at the front end of the first positive coil segment. The negative winding segment winds around the outer periphery of the first positive coil segment to the inner side of the top of the first positive coil segment and then extends downward to the first intermediate separator layer, extending along the first intermediate separator layer towards the bottom of the positive coil to form a U-shape. The positive and negative winding segments overlap in the middle, with the positive winding segment pressing on the outer side of the negative winding segment.

[0008] As a further improvement to the above technical solution, the rear section of the positive electrode winding segment is located at the bottom of the second negative coil segment, and the rear section of the negative electrode winding segment is located at the bottom of the second positive segment.

[0009] As a further improvement to the above technical solution, the length of segment A4 is greater than the total length of segments A1, A2 and A3, and the length of segment B4 is greater than the total length of segments B1, B2 and B3.

[0010] As a further improvement to the above technical solution, both the positive and negative power supply lines are composed of more than 20 copper wires.

[0011] The beneficial effects of this utility model are as follows: The positive and negative power supply wires are wound around the positive and negative power supply coils. The positive coil includes a first positive coil segment and a second positive coil segment, and the negative coil includes a first negative coil segment and a second negative coil segment. The middle of the positive and negative power supply wires includes a positive winding segment and a negative winding segment. The positive winding segment winds around the outer periphery of the first negative coil segment to the inner top of the first negative coil segment and then extends downwards to the second intermediate separating layer, extending along the second intermediate separating layer towards the bottom of the negative coil to form a U-shape. The negative winding segment winds around the outer periphery of the first positive coil segment to the inner top of the first positive coil segment and then extends downwards to the first intermediate separating layer. The circuit extends along the first intermediate separator towards the bottom of the positive coil, forming a U-shape. The positive and negative winding segments overlap in the middle, with the positive winding segment pressing against the outside of the negative winding segment. This causes the current signals of the power supply positive line, negative signal line, positive signal line, and power supply negative line to overlap at this point. Furthermore, the current flow directions of each wire bundle are regularly intersecting and opposite, causing the opposite magnetic fields generated by their respective currents to superimpose and cancel each other out. This avoids mutual interference between the power supply positive line, power supply negative line, positive signal line, and negative signal line, making the current signal more faithful and thus the transmitted sound signal more accurate.

A second intermediate separator layer 533 is formed between the first negative coil segment 531 and the second negative coil segment 532. The front end of the first negative coil segment 531 is connected to segment B2 52, and the rear end of the second negative coil segment 532 is connected to segment B4 54. The positive and negative coils are arranged in parallel and insulated from each other, and the positive and negative coils rotate in the same direction; segment A4 44 and segment B4 54 are composed of several single copper wires with an insulating layer between them.

[0021] Both the positive power supply line 20 and the negative power supply line 30 are composed of several copper wires. The positive power supply line 20 includes a positive winding segment 21 in the middle. The front end of the positive winding segment 21 is located at the front end of the first negative coil segment 531. The positive winding segment 21 winds around the outer periphery of the first negative coil segment 531 to the inner side of the top of the first negative coil, then extends downwards to the second intermediate separating layer 533, and extends along the second intermediate separating layer 533 towards the bottom of the negative coil, thus forming a U-shape. The negative power supply line 30... The middle part includes a negative electrode winding segment 31. The front end of the negative electrode winding segment 31 is located at the front end of the first positive coil segment 431. The negative electrode winding segment 31 is wound around the outer periphery of the first positive coil segment 431 to the inner side of the top of the first positive coil segment 431 and then extends downward to the first intermediate partition layer 433. It extends along the first intermediate partition layer 433 toward the bottom of the positive coil to form a U-shape. The positive electrode winding segment 21 and the negative electrode winding segment 31 overlap in the middle and the positive electrode winding segment 21 is pressed on the outside of the negative electrode winding segment 31.

The positive winding segment 21 and the negative winding segment 31 overlap in the middle and the positive winding segment 21 is pressed on the outside of the negative winding segment 31. This causes the current signals of the power supply positive line 20, the negative signal line 50, the positive signal line 40 and the power supply negative line 30 to overlap at this point. The current flow directions of each wire bundle are regularly intersecting and opposite in direction. The opposite magnetic fields generated by their respective currents during the flow process are superimposed and canceled out, thereby avoiding mutual interference between the power supply positive line 20, the power supply negative line 30, the positive signal line 40 and the negative signal line 50. This makes the current signal more faithful and the transmitted sound signal more accurate.

[0023] In this scheme, the rear section of the positive winding segment 21 can be located outside the second negative coil segment 532, and the rear section of the negative winding segment 31 can be located outside the second positive coil segment 432.

[0024] In this scheme, preferably, the length of segment A4 44 is greater than the total length of segment A1 41, segment A2 42 and segment A3 43, and the length of segment B4 54 is greater than the total length of segment B1 51, segment B2 52 and segment B3 53.
