Description

The built-in backguy Headphone device of handheld mobile device

Technical field

The utility model relates to the built-in backguy Headphone device of a kind of handheld mobile device, belongs to family expenses electrical appliance accessory technical field.

Background technology

Along with the raising of people's material and cultural life, mobile electronic products such as mobile phone, mobile TV, MP3, MP4, cordless telephone, hand held television, learning machine have become the family life necessity.But these products are furnished with earphone, and conventional earphone is external, connect the hole by earphone and connect, and realize answering.

But earphone cord often all is rolled into one, and earphone cord is very difficult to make in order, uses pretty troublesome.But along with the use of products such as mobile phone, people realize symptoms such as the radiation meeting of electronic products such as mobile phone causes headache, and whole body is uncomfortable sometimes, but electronic products such as mobile phone are again the articles for use that be unable to do without in people's modern life.

Therefore wish to design a kind of earphone and use not messyly, do not bother, electromagnetic radiation is to the influence of brain in the time of can helping people to solve direct use receiver again.Earphone is built-in, adopt backguy to pull out, the method for withdrawal, the angle from using has at first made things convenient for and has carried, and has saved and has gone out all will carry a rough-and-tumble earphone cord at every turn, reduces belongings quantity in the pocket; Secondly, when using earphone at every turn, rough-and-tumble earphone cord be made in order is a very thing of trouble, built-in earphone is very convenient to use along the backguy groove by the mode of backguy, using up the back easily regains earphone cord by the retraction mechanism of earphone cord rear end exquisiteness, made loaded down with trivial details in the past line operation become and lift a finger, use free and relaxed.Simple to operate clear.

Summary of the invention

The purpose of this utility model is to provide a kind of handheld mobile device built-in backguy Headphone device, and this Headphone device has Portability, and is easy to use, conserve space on the structure.

For achieving the above object, the technical solution of the utility model is: this built-in backguy Headphone device comprises external earphone cord (3), shell (1), movement wiring board (2), also comprises trunking (4) in, card wiretap (5), spool and earphone cord (6); Interior trunking (4) places shell (1) one side, and earphone cord (3) is built in interior trunking (4), and card wiretap (5) is positioned at trunking (4) lower end, and spool and earphone cord (6) are positioned at trunking (4) end.By an embedded wire casing, the earphone heads of outside and the ball of string of machine bottom are coupled together, fixed the trend of earphone cord simultaneously, avoid occurring the phenomenon of earphone cord knotting.The earphone cord of machine bottom all twists in the rolling spring regularly, has saved the space, and the effect of spring simultaneously can guarantee that the earphone cord of pulling out can regain smoothly; The design of card wiretap guarantees the user when using earphone, and earphone cord is without automatic drawing back; When the user uses earphone, dial the lower card line switch, earphone cord uses very convenient with regard to automatic drawing back.

The beneficial effects of the utility model: built-in earphone, strengthen Portability, the withdrawal of stay-supported, conserve space, built-in earphone, save the use of connector, reduce the cost of whole hardware system,, avoid people to use the receiver of products such as mobile phone for a long time applicable to as mobile electronic products such as mobile phone, mobile TV, MP3, MP4, cordless telephone, hand held television, learning machine etc., and bring the electromagnetic radiation of human body, have tangible Jing Economic benefit and social benefit.

Below in conjunction with drawings and Examples to the technical scheme of the present utility model detailed explanation of making comparisons.

Description of drawings

Fig. 1. be the external Headphone structure schematic diagram of tradition;

Fig. 2. be the built-in earphone structural representation;

Fig. 3. be built-in Scroll spring and the backguy schematic diagram in the built-in earphone structure.

Embodiment
