Abstract

The utility model discloses a novel twist tension rupture prevention earplug type earphone, comprising an earphone; an electronic component arranged in the earphone shell and connected with an earphone conduction wire; a conduction pipe arranged on the end of the earphone shell and capable of forming an annular angle when the conduction pipe bends and telescopes and through which the earphone conduction wire passes; a spring arranged in the earphone shell and through which the earphone conduction wire passes and a projection node arranged on one end of the spring far away from the end of the earphone shell. The damage on the earphone due to impact tension, bending and twisting is effectively reduced, the service life of the earphone is prolonged and the use cost of the consumer is reduced.

Description

A kind of PlayGear Stealth of novel anti-distortion tensile failure
Technical field
The utility model relates to a kind of new earplug formula earphone, relates in particular to a kind of PlayGear Stealth of novel anti-distortion tensile failure.
Background technology
At present; PlayGear Stealth structure on the market generally comprises the earphone outer covering that is used to hold the earphone electronic unit; Earphone cord passes earphone outer covering and is connected with the earphone electronic unit; The phenomenon damaged very easily appears in the earphone of this structure, especially earphone outer covering terminal with the earphone cord contact position, and loudspeaker and earphone cord welding position are that the position artificially damaged very easily takes place.
The user is in long-term use; Appear at the situation that the user pulled at, dragged earphone cord unintentionally through regular meeting; Make earphone cord and loudspeaker welding position be very easy to fracture, simultaneously earphone outer covering terminal with the earphone cord contact site because user's long-term bending, distortion make the earphone cord of this contact portion very easily rupture.Above-mentioned two kinds of situation very easily produce damaging influence to earphone, and it can not be played sound, and causes users need be bought new earphone.
This shows that prior art needs further improvement and develops.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of PlayGear Stealth of novel anti-distortion tensile failure.
Its technical solution is:
A kind of PlayGear Stealth of novel anti-distortion tensile failure; Comprise earphone outer covering, in earphone outer covering, be provided with electronic unit, electronic unit links to each other with the earphone lead; At the earphone outer covering end conduit that forms fillet when one bending is stretched is set, the earphone lead passes from conduit.
At earphone outer covering set inside one spring, the earphone lead passes from spring, and makes a call to a projection node at spring away from the terminal end of earphone outer covering.
The useful technique effect of the utility model is:
The utility model can effectively reduce impact tension and the injury to earphone is twisted in bending, has prolonged the useful life of earphone, has reduced consumer's use cost.
Description of drawings
Fig. 1 is the structural principle sketch map of the utility model.
Embodiment
The utility model relates to a kind of PlayGear Stealth of novel anti-distortion tensile failure.For the purpose, technical scheme and the advantage that make the utility model is clearer, clear and definite, below will combine accompanying drawing and embodiment, to the utility model further explain.
A kind of PlayGear Stealth of novel anti-distortion tensile failure comprises earphone outer covering 1, in the set inside of earphone outer covering 1 electronic unit is arranged, and electronic unit is connected with an end of earphone lead 2, the other end attachment plug of earphone lead 2.End at earphone outer covering 1 is provided with a conduit 3; Conduit 3 is bent flexible and be provided with many not only thin but also close folds on the surface; When passing the earphone lead 2 here when crooked, conduit 3 can form fillet, has so just reduced to bend the damage to earphone lead 2 greatly.What this need particularly point out be, the diameter that is used to produce the conduit 3 of fillet can not be thick excessively, lead is passed get final product, the fold on conduit 3 surfaces must be not only thin but also close and diameter should be slightly larger than other parts of conduit 3.Conduit 3 usefulness glue also can take other fixed forms to fix at the end of earphone outer covering 1 certainly.At set inside one spring 4 of earphone outer covering 1, the earphone lead passes from spring 4, and makes a call to a projection node 5 at spring away from the terminal end of earphone outer covering, and the body footpath of projection node 5 is greater than the internal diameter of spring 4.When the earphone lead received the external shock pulling force, projection node 5 made spring 4 compressions like this, can cushion certain-length after spring 4 compressions, had reduced external shock power greatly to the earphone infringement of structure everywhere.Further; When spring 4 in the raw the time; Should be in the natural length under the tight state greater than the earphone lead from projection node 5 to this section earphone conductor length with the electronic unit junction; The earphone lead that is to say this part is in very lax state, the infringement that can protect earphone to avoid pulling to greatest extent like this.
Need to prove that under the instruction of this specification, any equivalents that those skilled in the art have done, or obvious variant all should be within the protection ranges of the utility model.

Claims (2)

1. the PlayGear Stealth of a novel anti-distortion tensile failure; Comprise earphone outer covering, in earphone outer covering, be provided with electronic unit, electronic unit links to each other with the earphone lead; It is characterized in that: at the earphone outer covering end conduit that forms fillet when one bending is stretched is set, the earphone lead passes from conduit.
2. the PlayGear Stealth of a kind of novel anti-distortion tensile failure according to claim 1 is characterized in that: at earphone outer covering set inside one spring, the earphone lead passes from spring, and makes a call to a projection node at spring away from the terminal end of earphone outer covering.
