Description

A kind of earphone with scalable wire rod

Technical field:

The utility model relates to technical field of electronic products, refers in particular to a kind of earphone with scalable wire rod.

Background technology:

Along with improving constantly of people's living standard, various stereo sets are widely used.At present, in people's life, study, work, the user of a people one machine is very general, and for when many people use different acoustic equipment simultaneously, the sound of generation can not cause interference to other people, and listening device just must adopt earphone.Traditional wired earphone all needs to connect long earphone cord, use inconvenience if earphone cord is short, if but earphone cord is long, then earphone cord in use can form yoke to user or the people who walks about by it, and brings puzzlement and trouble.And the earphone cord long term exposure in outside, dirty by the environment easily or situation that meets accident and damage.

Summary of the invention:

The purpose of this utility model is intended to overcome the deficiency of the said goods, provides a kind of and uses convenient, operation to carry more convenient a kind of earphone with scalable wire rod than present wired earphone.

The utility model is achieved by the following technical solution: it comprises the auricular concha that constitutes headset main body and disc, be fixed on loudspeaker on the disc, be installed in the main body drawing mechanism be connected and earphone wire rod on drawing mechanism, wherein drawing mechanism comprises that mainly a wind spring, reel are fixed on the support plate on the disc, wherein reel is set on the fixed leg on the support plate, and the two ends of wind spring are individually fixed on fixed leg and the reel, wire rod one end is fixed on the reel, and the other end that is provided with plug passes the hole slot offered on the auricular concha to main body.

Above-mentioned a kind of earphone with scalable wire rod also comprises a positioner.This positioner comprises that one is hinged on grab and on the disc and is connected spring between grab and the disc upper pin, and the position of corresponding grab offers the through hole that resets on auricular concha in addition; On reel, offer the location notch corresponding with grab.

The utility model adopts this mode, integrated the advantage of wired earphone and wireless headset, telescopic wire rod is built in the earphone case, no matter the utility model is used for stereo sets such as MP3, CD, computer, radio-cassette player, mobile phone, and the user can go out wire stretching suitable length and use.Because wire rod can freely stretch, and does not have unnecessary sensation fully, make troubles can for user or its people by the side of.After wire rod is drawn out, touch built-in grab by the through hole of offering on the earphone case that resets wire rod is regained, make wire rod in earphone case, obtain pollution and damage that better protection is avoided external environment.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is a perspective exploded view of the present utility model;

Fig. 3 is an audio signal transmission flow chart of the present utility model.

Embodiment:

The following stated only is a specific embodiment of the present utility model, does not therefore limit protection range of the present utility model.

See accompanying drawing 1,2, the utility model comprises: headset main body 1, loudspeaker 2, drawing mechanism 3, earphone wire rod 4, positioner 5, microphone 6, double-sided PCB 7 and contact flat spring 8.Wherein headset main body 1 is made of auricular concha 11 and disc 12, and disc 12 is affixed on user's ear in use, and loudspeaker 2 are fixed on the disc 12 by grab.Described drawing mechanism 3 mainly comprises a wind spring 31, reel 32 and is fixed on support plate 33 on the disc 12, and wherein reel 32 is set on the fixed leg 331 on the support plate 33, and promptly reel 32 can rotate around fixed leg 331.Support plate 33 is fixed by the bearing pin that is provided with on the disc 12, and promptly support plate 33 connects with disc 12 fixing by the hole axle.The two ends of wind spring 31 are separately fixed on fixed leg 331 and the reel 32, and wire rod 4 one ends are fixed on the reel 32, and the other end that is provided with plug 41 passes the hole slot 111 offered on the auricular concha 11 to main body 1.Contact flat spring 7 is fixed on the reel 32, and the lead in this contact flat spring 7 and the wire rod 4 is communicated with, and also is provided with double-sided PCB 8 between reel 32 and support plate 33, and contact flat spring 7 just in time presses on the surface of double-sided PCB 8, with the connection of realization circuit.

Positioner 5 is the purposes that realize the location of reel 32, so that wire rod 4 can not withdrawn.Wherein positioner 5 comprises that one is hinged on grab 51 and on the disc 12 and is connected spring 52 between grab 51 and disc 12 upper pins, and the position of corresponding grab 51 offers the through hole 112 that resets on auricular concha 11 in addition; On reel 32, offer location notch.Grab 51 is close on the reel 32 under spring 52 elastic force effects, and can realize with reel 32 on the inlay card effect of location notch, prevent that reel 32 from rotating under the effect of wind spring 31.In addition can steady operation in order to ensure wind spring 31, on wind spring 31, also fix a wind spring compressing tablet 34.

In addition, the utility model also can be provided with a microphone 6 on auricular concha 11.

When using the utility model, at first pull out plug 41, wire rod 4 will drive reel 32 rotations, can reel 32 be automatically locked by grab 51 in rotary course, prevent reel 32 counter-rotatings.In the time of rotation, the fixed leg 331 of wind spring 31 on support plate 33 oppositely curls, and promptly the elastic potential energy of wind spring 31 increases.When wire rod 4 stops to stretch, reel 32 stops operating, under the wind spring 31 elastic force effects and under spring 52 effects, location notch on grab 51 inlay cards and the reel 32, with reel 32 lockings, wire rod 4 with reel 32 stop motions, can not bounce back yet, this moment, the length of wire rod 4 was fixed, and suitably adjusted to make wire rod 4 stretch out ideal length.When not using the utility model, plug 41 can be inserted in the through hole 112 that reset, promote grab 51 afterbodys by plug 41 tops, make it overcome spring 52 pulling force and rotate the location notch that grab 51 is broken away from the reels 32.Reel 32 drives reel 32 reverse rotations under wind spring 31 reaction forces, wire rod is rewound on the reel 32.Thus, the utility model has been realized the flexible purpose of earphone wire rod 4.

See accompanying drawing 3, this is the utility model audio signal transmission flow chart, and concrete workflow is as follows:

1, external audio frequency signal right horn plug 41 and wire rod 4 be through the contact flat spring 7 on the reels, by double-sided PCB 8 audio signal transmission given to be installed on the disc 12 loudspeaker 2, to realize sounding.

2, the microphone 6 that is contained on the earphone auricular concha 11 converts tones into audio signal, is transferred out through wire rod 4 and phono connector 41 signal with microphone 6 by contact flat spring 7 by double-sided PCB 8.

The utility model does not have unnecessary sensation fully because wire rod 4 can freely stretch, and makes troubles can for user or its people by the side of.After wire rod 4 is drawn out, touch built-in grab 51 by the through hole of offering on the earphone case 11 112 that resets wire rod 4 is regained, make wire rod 4 in earphone case, obtain pollution and damage that better protection is avoided external environment.
