Description

High tensile strength enameled stranded wire for earphone

Technical Field

The utility model relates to a wire and cable correlation technique field, specifically speaking relates to an adopt high tensile material to add the enameled wire that special transposition structure made, and this stranded conductor has the advantage that tensile strength is higher than ordinary enameled wire, is particularly suitable for application occasions such as earphone cord.

Background

With the popularization of mobile electronic devices, the demand of earphones, particularly high-end earphones, in the market is increasing. Although the wireless earphone has the characteristic of convenient use, the wireless earphone still cannot be compared with the wired earphone in the aspects of high power and low noise. Therefore, wired headphones remain the mainstream of the market. In order to improve the high-frequency performance of earphones, the industries increasingly adopt the earphone wires with enameled stranded wires as core wires in recent years. The enameled stranded wire is used as an earphone wire core wire, the single wire of the enameled stranded wire is usually in a small specification, and the wire diameter is generally between 0.04 and 0.08. Such a thin wire diameter makes it the most challenging how to improve the tensile strength in the earphone-like application.

In order to improve the tensile property of the core wire of the enameled stranded wire of the earphone, the stranded wire can be made into a structure with a thick paint film and a small lay length, but the tensile property of the enameled stranded wire is limited by the material property, and the improvement of the tensile property of the enameled stranded wire brought by the improvement of the existing structure is also limited. Therefore, a new stranded wire structure is formed by adding a material with high tensile strength on the basis of the existing stranded wire structure, so that the tensile property of the enameled stranded wire is greatly improved.
