Description

A kind of graphene earphone cord for being difficult winding

Technical field

The utility model is related to a kind of earphone cord, and in particular to a kind of graphene earphone cord for being difficult winding.

Background technology

Earphone is one of indispensable accessory of current various video and audio electronic products (such as computer, phone, MP3 etc.), For listening to audio file, its structure includes the earphone contact pin for being used to receive electronic signal, and electronic signal is converted into acoustical signal Loudspeaker, and transmission signal earphone cord.The common earphone cord of in the market by inner conductor and it is outer constituted by flexible glue, wherein Inner conductor is generally copper cash, outer to be generally PVC, TPU and TPE material by flexible glue.

Relative and wireless headset, wired earphone is also because the transmission of its signal is more excellent and continues prevalence, and people are to ear The requirement more and more higher of machine tonequality audio.But, the earphone cord of wired earphone can not bear larger pulling force, so as to reduce whole The service life of individual wired earphone.In the case of Radiationproof screening apparatus for back-located antenna mobile telephone being connected particularly in earphone cord, Radiationproof screening apparatus for back-located antenna mobile telephone and earphone The pulling force that line is born is smaller, can only typically bear 1 to 2KG tensile test, and find the cored wire inside earphone cord relative to Earphone cord epidermal glide is damaged；In addition, the wire rod of earphone is to influence the important portion of earphone quality and usage experience in wired earphone Part, the cross section of the wire rod of majority earphone is circular or platypelloid type at present, and diameter is thinner, although carrying convenient, it has Have and easily occur winding, knotting phenomenon, not easily contained, the shortcomings of reducing the experience of user.

Accordingly, it would be desirable to which a kind of signal transmission and electric conductivity are more preferably, tensile capacity is stronger, and is difficult the earphone of tangled up and knotted Line, to avoid drawbacks described above.

Utility model content

In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of graphene for being difficult winding Earphone cord.The technical problems to be solved in the utility model is achieved through the following technical solutions：

A kind of graphene earphone cord for being difficult winding, including core and serving, the core are located at the inside of serving, The section of the serving is triangle；The core includes the conductor of inside and the screen layer of conductor outer wrapping；The core There are 3 groups, in equilateral triangle arrangement；There is packed layer between serving and core；The conductor is graphene material, described outer Tegillum is TPE materials.

Further illustrated as of the present utility model, the earphone cord is set with the plug end and use for being used to connect plug In the earphone end of connection earphone, the plug end is respectively provided with wired shelves with the earphone end.

Further illustrated as of the present utility model, the section of the line shelves is triangle.

Further illustrated as of the present utility model, the serving is SBS or SEBS styrenic elastomers.

Further illustrated as of the present utility model, the screen layer is worked out by wire netting.

Further illustrated as of the present utility model, the packed layer is nylon yarn or Huang Dansi.

Further illustrated as of the present utility model, the earphone cord is the earphone cord of built-in earplug machine.

Compared with prior art, the beneficial effects of the utility model are：

1. due to earphone cord serving be triangular-section, and the cylinder of triangular-section have stronger stability and Self-recovery ability, effectively prevent earphone cord and mutually winds and knot, both facilitated and used, and effectively extend earphone Life-span.

2. the utility model is using conductor of the graphene as earphone cord, compared with common copper wire conductor, signal transmission With electric conductivity more preferably, tensile capacity is stronger.

The utility model is described in further details below with reference to drawings and Examples.
