Manufacture method for earphone wires

Abstract

The invention discloses a manufacture method for earphone wires. The manufacture method comprises the following steps: a, a wire is cut according to dimension requirement, and one end of the wire is welded on an earphone plug; b, the welded earphone plug is sequentially subjected to inner mould injection and outer mould injection; c, stripping is performed from the middle part of the wire to an end which is far away from the earphone plug, and a core wire is divided into two strands according to requirement; e, the two strands of the core wires are separately inserted into a sleeve pipe; then the sleeve pipe and the stripped part of the middle part of the wire are sequentially subjected to middle buckle inner mould injection and middle buckle outer mould injection; and before the core wires are inserted in the sleeve pipe, a step d is performed, namely a tail baffle is injected at one end of the sleeve pipe, and then the sleeve pipe is cut from the tail baffle according to a required dimension. By adopting the manufacture method, operation difficulty of workers can be lowered; the length of the earphone wire is conveniently controlled; the production efficiency and qualification rate of earphones are improved; cost is lowered; and the like.

Description

technical field [0001] The invention relates to the technical field of earphone production, in particular to a method for manufacturing and processing earphone wires. Background technique [0002] In recent years, with the development of smart phones, the screens of mobile phones have become bigger and bigger, and the sound quality of mobile phones has become better and better, making more and more people choose to use smart phones to watch movies and TV programs or enjoy songs, and earphones have become a travel option. An essential companion. In addition to watching movies and TV programs or enjoying songs, smart phones are mainly used for calls. For the convenience of people to answer calls normally, a microphone and an answering switch are also provided on the common mobile phone earphone line. The microphone and the answering switch of the earphone are integrated on the circuit board, and one end of the circuit board is welded and fixed with the earphone wire, and at t...

Problems solved by technology

When the tail gear is injected, it is necessary to use a measuring tool to determine the injection position of the tail gear, and then carry out injection molding. Since the overall diameter of the sleeve is linear, the sleeve will move in the injection mold, making the injection position of the tail gear prone to deviation. , eventually causing the length of the headphone cable to fail to meet the size requirements and the entire headphone is scrapped
