Manufacturing technique for double-core shielding small-signal transmission wire for audio equipment

Abstract

The invention discloses a manufacturing technique for a double-core shielding small-signal transmission wire for audio equipment. The manufacturing technique comprises the following steps: S1, stranding purchased copper wires into a plurality of strands of bare copper wires according to requirements of a customer order; S2, carrying out extrusion molding on the strands of the bare copper wires obtained through the stranding according to the requirements of the customer order, so that single signal wires are obtained; S3, stranding two of the single signal wires, which are obtained through theextrusion molding in S2, with cotter fibers; S4, adding a step after S3 to invert the two single signal wires stranded with the cotton fibers; and S5, adding tin foil paper and a copper wire woven netto a plurality of strands of cotton-containing fibers obtained through stranding in S4. The manufacturing technique disclosed by the invention has the advantages that through the direction change ofthe signal wire, the audio transmission direction characteristic of the double-core small-signal wire is right opposite to the audio transmission direction characteristic of a ground wire when the double-core small-signal wire is applied in an audio product, so that the characteristic that sounds come from the nature and return to the nature can be better reflected, the fidelity of the audio product can be greatly improved, and better use effects, lower cost and a long service life can be achieved.

Description

technical field [0001] The invention relates to the technical field of audio wires, in particular to a manufacturing process of a double-core tape-shielded small-signal transmission line for audio. Background technique [0002] Sound is a simplified everyday word, which is the abbreviation of sound system. That is to say, it refers to a complete set of equipment that can restore and play audio signals. With the progress of society, people yearn for more colorful life. As a form of entertainment that has been passed down for thousands of years, singing and dancing has penetrated into the lives of people of all ethnic groups. However, with the development and progress of science and technology, people have more and more requirements for the performance forms and venues of singing and dancing. The sound system is constantly improved and perfected according to people's needs. It is large enough to meet the live sound reinforcement needs of tens of thousands of concerts, and s...

Problems solved by technology

[0005] At present, the shielded small-signal dual-core produced in China generally has unsatisfactory sound quality. We have carefully analyzed more than a dozen domestic manufacturers of similar wires, and compared them with international brands such as Canai and American Monster. Through a large number of The experimental certification of the domestic audio wire factory found that the process flow of similar dual-core shielded small signal transmission lines in our domestic audio wire factory was not standardized, which seriously affected the development of the audio industry, resulting in poor fidelity and unsatisfactory effect of the audio cables produced, which eventually caused The effect of the audio system we matched is greatly reduced, and it is easy to mislead the audio engineer to misunderstand and misoperate during operation and use, resulting in easy damage to the equipment. Therefore, we propose a dual-core tape shielded small signal transmission line for audio production process to solve the above problems
