Abstract
The present invention provides an earphone line, an earphone line take-up apparatus, an earphone assembly and a mobile terminal. The earphone line comprises a bullet-proof fiber, insulated conductive wires and an earphone line skin, wherein: the earphone line further comprises conductors; the insulated conductive wires are wound around the bullet-proof fiber in a spiral fashion; the earphone line skin is attached to and wrapped on a surface of the insulated conductive wires to form a layer of super-thin, flexible and wear-resistant earphone line skin; and the conductors are at two ends of the earphone line and are to be connected to output and input ends of a signal connecting apparatus and of the earphone respectively during use. The present invention further provides a method for manufacturing the earphone line. Contrary to the traditional earphone line which is bulky and stiff and easy to be broken after hundreds of times of coiling, the new type earphone line of the present invention is very fine and flexible and possible to be coiled tens of thousands of times without being broken and can meet the life time requirement for the “built-in retractable earphone”.
