Description
Technical field
The utility model relates to a kind of earphone cord, more specifically to a kind of earphone cord that can avoid earphone cord generation winding effectively.
Background technology
At present, the earphone cord that earphone adopts generally includes the rounded rubber sleeve of profile and at least one lead (the simplest lead only comprises a copper wire) that is located in the rubber sleeve.
Because the length of earphone cord and the ratio of diameter are extremely lacked of proper care, and have caused it very easily to be bent.Add rubber sleeve under external force, reversing around its axis (being wire) easily taken place.This has just caused the unsteadiness that has at least 3 dimensions (bend right and left, front and back are crooked and reversing around axis) on the earphone cord structure, and intensity is big when axially pullling, and other direction almost can be thought no intensity.
In addition, the wire rod of earphone is owing to the reason of wearing, be designed to front end and must be branched into two strands, finally become the structure of " Y " font, we can think roughly, earphone cord is shape conversion each time, all involves the variation of the individual different dimensions of 9 (per share dimension is independently), just nine dimensional vectors being combined into of 3 three-dimensional vectors (a bar earphone has 3 lines).
Earphone cord twines, and is exactly the reason that Water seeks its own level frankly speaking in fact.This is the embodiment of minimum energy principle.Draw an analogy: in a single day breach appears in the pond of eminence, is exactly a labile state, must shift to stable state (lower).
After we just put earphone into pocket without arrangement, earphone cord can be considered as being forced to motion under the external force effect at random.So, earphone cord similarly is water, and it will certainly " push oneself " to a stable status, to overcome the effect of external force.Final result just becomes: self the twining of earphone cord, i.e. our skein tangle up of seeing.
In order to solve the problem that earphone cord twines easily, people have carried out various improvement to the structure of earphone, but this method is by earphone cord being wrapped on the structures such as twining frame, replacing the rambling winding of earphone cord with orderly winding.Though this method can be dealt with problems, each winding all needs to expend a large amount of time of user, very trouble.
In order better to solve the problem that earphone cord twines easily, there is the people that the rubber sleeve configuration design of earphone cord is become flat, adopt the earphone cord of this flat rubber cover because therefore the earphone cord of the similar noodles of its profile is commonly called the noodles earphone cord.Therefore the noodles earphone cord has effectively solved the problem that earphone cord twines easily because the width of flat rubber cover is far longer than thickness.
But the applicant finds that excessive stretcher strain takes place the flat rubber cover easily under the pulling force effect, and excessive stretcher strain meeting damages lead.If the material to the flat rubber cover improves, and in the flat rubber cover, increase the stretch-proof structure, then can significantly increase the production cost of earphone cord, cause earphone cord can't be applicable to the highstrung low and middle-grade earphones of price.
The utility model content
Technical problem to be solved in the utility model is to be enclosed within easy deformation under the pulling force effect at the prior art flat rubber, the shortcoming that meeting damages lead, a kind of earphone cord is provided, this earphone cord can be avoided flat rubber cover excessive deformation effectively, and it is simple in structure, be easy to realize, cost is low.The technical scheme that adopts is as follows:
A kind of earphone cord comprises flat rubber cover and at least one lead that is located in the flat rubber cover, it is characterized in that: described earphone cord comprises that also litzendraht wire prevent the stretching overcoat, and described litzendraht wire prevents that the stretching overcoat is enclosed within flat rubber and overlaps on the outer surface.The anti-stretching overcoat of described litzendraht wire is formed by braid, because litzendraht wire can bear bigger pulling force and distortion is very little, therefore earphone cord is done the time spent being subjected to pulling force, the anti-stretching overcoat of litzendraht wire and flat rubber cover bear pulling force jointly, because the anti-stretching overcoat distortion of litzendraht wire is little, it has limited the deformation extent of flat rubber cover, allows the flat rubber cover can not produce excessive deformation, thereby avoid lead is damaged, the tensile property of earphone cord is significantly improved.
A kind of preferable scheme, described flat rubber are overlapped the rectangle that is shaped as of cross section.
Another kind of preferable scheme, described flat rubber are overlapped the ellipse that is shaped as of cross section.
The scheme that the third is preferable, described flat rubber are overlapped the prismatic that is shaped as of cross section.
Better scheme, described lead outer surface is provided with insulating barrier.
The utility model beneficial effect against existing technologies is, because the outer surface at the flat rubber cover has put the anti-stretching overcoat of litzendraht wire, therefore when earphone cord is subjected to pulling force, can avoid the flat rubber cover that excessive deformation takes place effectively, thereby avoid lead to come to harm, it is simple in structure, result of use is very good, be easy to make, cost is low, is particularly useful for the highstrung low and middle-grade earphones of price.
