Embodiment 1

As shown in Figs. 1-2, the utility model provides a kind of earphone cable, including earphone cable 1, and one end of earphone cable 1 is provided with Plug 2, the other end of earphone cable 1 are provided with middle part mould 3, and plug 2 is to being disposed with ferrite coil 4, slow between middle part mould 3 It breasts the tape circle 5, earphone cable 1 passes through middle part mould 3 and divides for left tramline 6 and auris dextra line 7, and left and right line 6 is socketed with 7 outer end face of auris dextra line Separated time pitches mould 8, and for auris dextra line 7 through there is wire-controlled apparatus 9, left and right line 6 and one end of auris dextra line 7 are provided with earplug 10, earphone cable 1 Be internally provided with several conducting wires 12 and reinforced-core 11, the outer end face of conducting wire 12 is coated with inner insulating layer 13, insulating layer 13 Outer end face be coated with shielded layer 14, reinforced-core 11 is located at 12 two sides of conducting wire and is parallel to each other, the outer end of shielded layer 14 packet It is covered with external insulation layer 15, the outer end of external insulation layer 15 is coated with antistatic layer 16.

Further, earphone cable 1 is flat structure, and flat structure can make wire rod be not easy to wind clot.

The quantity of conducting wire 12 is six, and the quantity of reinforced-core 13 is two, and six conductors 12 are respectively L channel line, right channel Line, L channel ground wire, right channel ground wire, common ground line, microphone lines, reinforced-core 13 are located at two sides and are able to ascend earphone cable 1 anti-pull property.

External insulation layer 15 is TPU material, and the entitled thermoplastic polyurethane elastomer rubber of TPU, this material can be certain Soften under temperature, and can remain unchanged at normal temperature, while there is good wearability.

Buffer coil 5 is ring-like coil structure, when buffer coil 5 is stretched because elastic type becomes, after external applied load removal Elastic recovery is generated, the variation for making the shape of buffer coil 5 and size all occur and change in the opposite direction when load, to make to delay Circle 5 of breasting the tape restores as former state.

Shielded layer 14 is mainly that metallic film is made, and has ego resilience effect, while having function of shielding.

Reinforced-core 11 is mainly that alkali-resistant glass fibre is made, and alkali-resistant glass fibre has stronger crack resistance and tension Property, can be good at that earphone cable is protected not to be torn.

Antistatic layer 16 be polyester filament weaved with high-performance permanent conductive fiber, with excellent antistatic, Anti-dust performance, antistatic efficiently, persistently have the characteristics that soft, thin cunning, weavy grain are clear.

Specifically, plug 2, which is inserted into audio frequency apparatus, carries out signal transmission, earplug 10 is transmitted a signal to by earphone cable 1, To realize the function of listening to music, separated time, which pitches mould 8, to carry out beam conjunction for left and right line 6 and auris dextra line 7, so as to according to user's Demand is adjusted, and buffer coil 5 is ring-like coil structure, stretches buffer coil 5 when user shakes to pull because of head, from Without causing to pull sense to ear, high-frequency signal is filtered loss by ferrite coil 4, and low frequency signal is lost It is then less, to prevent from wearing when earphone listens song when charging to mobile phone and generating current sound, influences to wear, have inside earphone cable 1 Six conductors, respectively L channel line, right channel line, L channel ground wire, right channel ground wire, common ground line, microphone lines, from And audio signal can preferably be exported, be parsed, so that the sound for hearing earphone is more pleasing to the ear, at the same the outer end of conducting wire 12 according to Secondary to be enclosed with shielded layer 14 and inner insulating layer 13, shielded layer 14 is mainly that metallic film is made, and is filtered by hash Prevent the electric leakage of conducting wire 12 from earphone being caused to damage while shielding, while external insulation layer 15 is TPU material, is able to ascend earphone cable 1 Whole wearability, extends the service life of earphone, and the antistatic layer 16 of outer layer is that polyester filament and high-performance permanent are conductive Fiber weaving forms, and so that 1 outer layer of earphone cable is had excellent antistatic, anti-dust performance, prevents earphone from generating during wearing Electrostatic influence uses, while the generally flat structure of earphone cable 1, and earphone cable will not generate winding when carrying out earphone to receive whole, with Anti- needs, which often solve earphone cable 1 and bring inconvenience, to be influenced to use.

Finally, it should be noted that the above is only the preferred embodiment of the utility model, it is not limited to practical It is novel, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art, It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc. With replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all include It is within the protection scope of the utility model.
