Abstract

The utility model discloses a pair of clip type earphones which can be folded, comprising the earphones, a length adjustment bar, and a clip steel bar. The utility model is characterized in that the clip steel bar is formed by that a plurality of arced steel bars are connected by hinges. The outside of the connection position of the hinges has a block to cause the steel bars only to turn towards inner side. Therefore, the clip steel bar is opened and the earphones are put on. The clip steel bar of the utility model likewise has a definite elastic force. The clip steel bar is folded towards inner side when the earphones are not used. The compact form can be gotten, which is convenient for collection and taking.

Description

Folding earphone

The present invention relates to the hanging earphone of a kind of improved folder, particularly a kind of earphone that can be folded into compact form.

The hanging earphone of existing folder is mainly hung steel bar, length adjustment bar and earphone by folder and is formed.The effect that folder is hung steel bar is: 1, earphone is linked with on head.2, utilize the elastic deformation force of steel bar that earphone is close on two ears, and make whole pair of earphone be difficult for landing.This earphone is linked with comfortable, and acoustics is good, and is popular to people deeply, is the good companion who travels at home.Blemish in an otherwise perfect thing be that folder is hung steel bar and taken up space very much, be not easy to collection and carry.

Task of the present invention is to provide a kind of improved folder hanging earphone.During use, it is linked with effect and the hanging earphone of existing folder without any difference.When not using, but can fold up easily to be convenient to collect and carry.

Task of the present invention is finished as follows: it is to be formed by connecting with hinge by several sections arc-shaped steel bars that the folder of circular arc is hung steel bar.Per two steel bars can only be turned back and can not turn back to the circular arc outside to the circular arc inboard each other around hinge.Therefore, when being with earphone, the folder of being made up of several sections arc-shaped steel bars is hung steel bar like this, owing to can not turn back to the circular arc outside, two auricles force the whole sub-folder of earphone drive to hang steel bar and expand outwardly, and the deformation force of steel bar just makes earphone be close on two ears.When taking off earphone, it is folding to the inside to press from both sides the extension steel bar, just can make earphone be folded into very compact form.

Below with reference to accompanying drawing invention is done further to refer in detail state.

Fig. 1 is a kind of concrete structure schematic diagram of the present invention.

Fig. 2 and Fig. 3 are the hinge assemblies schematic diagrames of this structure.

Fig. 4, Fig. 5 and Fig. 6 are folding principle schematic of the present invention.

Referring to Fig. 1, it is to be formed by connecting by 4 sections arc-shaped steel bars, 1,2,3,4 usefulness, 3

secondary hinges

5,6,7 that the folder of this structure is hung steel bar.Hinge is design and installation like this: every secondary hinge is connected and composed by pin 10 with paying limit 9 by positive limit 8, referring to Fig. 2.Paying has hinge hole portion 11 and connecting portion 12 on the limit 9, then singly there are not pan portion 13 connecting portions 14 on positive limit 8, and a block 15 is arranged.Two steel bars, 3,2 ends that need to connect are just being paid the connecting portion 12,14 affixed (what draw on Fig. 2 is welding, and also available screw connects) on limit respectively with hinge.The pan on positive limit is neat with the hinge borehole jack of paying the limit then, penetrates pin 10 two steel bars are coupled together.Referring to Fig. 2, because block 15 restrictions on positive limit are paid limit 9 and can only be turned back to a side.Block is the outside that hangs steel bar at folder, then pays limit 9 and can only turn back to the inside.Therefore when being with earphone, owing to can not turn back laterally between per two sections steel bars, two auricles force earphone and whole folder to hang steel bar and expand outwardly, and the deformation force of steel bar just makes earphone be close on two ears, and the comparatively firm area of whole set of headphones is hung on the head.

When time spent not, will press from both sides and hang steel bar and turn up to the inside, referring to folding schematic diagram 4, Fig. 5 and Fig. 6.Just can get very compact form shown in Figure 6 after folding.Again it is packed in the box or in the sack, just very be easy to collection or go out to have carried.

Claims

1, the hanging earphone of being made up of earphone, length adjustment bar, folder extension steel bar of folder is characterized in that it is to be connected by several sections arc-shaped steel bars to form that folder is hung steel bar.

2, by the hanging earphone of folder of claim 1 regulation, it is characterized in that adopting between the arc-shaped steel bar hinge-coupled.

3, by the hanging earphone of folder of claim 1 or 2 regulations, it is characterized in that the hinge connection of two arc-shaped steel bars has a block, so that can only turn back to a side between two steel bars.
