Earphone cord

Abstract

The invention provides an earphone cord comprising an anti-elastic wire, an insulating conducting wire and an earphone cord skin. The earphone cord is characterized by also comprising conductive bodies, the insulating conducting wire is spirally wound on the anti-elastic wire; the earphone cord skin is adhered to and wraps on the surface of the insulating conducting wire to form an ultrathin, flexible and abrasion-resistant skin; and the conductive bodies are positioned on both end parts of the earphone cord and respectively connected with output and input terminals of electronic products and earphones. The invention also provides a method for manufacturing the novel earphone cord. Compared with the traditional earphone cord which is bulky and rigid and is easy to break when bent hundreds of times, the novel earphone cord is very fine and flexible, can not be broken when bent for tens of thousands of times and completely meet the requirements for the service life of built-in telescopic earphones.

Description

technical field [0001] The invention relates to a new type of earphone cable with "built-in telescopic earphone". Background technique [0002] At present, in the known technology and actual products, there is no earphone cable that can be stretched and curled into a narrow device, and there is no earphone cable that can be curled tens of thousands of times without breaking. However, with the advent of the 3G era, as earphones become more and more widely used, such as video calls, watching mobile TV, listening to music, etc., a new type of "built-in retractable earphones" will surely become a major demand in people's lives , and become an essential component of audio electronic products such as mobile phones, computers, and Walkmans. This new type of "built-in retractable earphone" is built into all electronic products with audio-visual audio, such as mobile phones, computers, and walkmans. Return it to the product. However, the "built-in retractable earphone" has not bee...

AI Technical Summary

Problems solved by technology

The headphone cable made by this construction process cannot be rolled back and forth thousands of times. During the process, because the radius of the earphone wire reel is very small, there will be mutual friction, gaps and looseness between several groups of conductors. After such a process continues hundreds of times, the insulating layer on the insulated conductive wire will be Electricity channeling caused by wear and tear leads to short circuit. After gaps are generated between several groups of conductors, it is easier to cause the skin of the earphone cable to expand and rupture under force. The insulated and conductive wires are also more likely to break. Therefore, the earphone wires produced by the known technology can only be damaged or broken after being crimped hundreds or thousands of times. No damage and no fracture service life requirements
