Embodiment

Embodiment 1: as shown in Figures 1 to 4, a kind of headphone of the present utility model, comprise elasticity headband 1, earmuff 2, supporting 3 and control device 4, earmuff 2 is established two two ends that are connected to elasticity headband 1, control device 4 is fixed on the earmuff 2, supporting 3 one ends links to each other with control device 4, the other end acts on postauricular head place, when the user puts on earphone, should support 3 forward auricle to after, and be bearing in postauricular head place, thereby the chucking power that elasticity headband 1 produces is transferred on the head, avoid the cartilaginous tissue of ear to be pushed for a long time, improve the comfortable wearing sense of earphone, even ear is not felt well or pain.The rotation and the location of control device 4 control supportings 3, it comprises housing 40, button 41 and is installed in elastic compression mechanism 5 in the housing 40, housing 40 is provided with button installing hole 401 and supporting installing hole 402, button 41 is set in the button installing hole 401, the one end places outside the housing 40, and the other end places in the housing 40; Supporting 3 ends that link to each other with control device 4 are set in the supporting installing hole 402 and extend to housing 40 inside, and the supporting 3 partial fixings that are positioned at housing 40 gear 31 is arranged, supporting 3 is passed gear 31 and is supported in the areole 42 of housing 40, is equiped with space washer 32 between another sidewall of housing 40 and the gear 31; Elastic compression mechanism 5 comprises pressing plate 51, spring housing 52, be sheathed on the back-moving spring 53 in the spring housing 52 and be located at back-moving spring positioning seat 55 on the earmuff 2, the middle part of pressing plate 51 is articulated on the housing 40 by jointed shaft 54, the one end is provided with the positioning tooth 511 that cooperates with gear 31, the other end is located between button 41 and the spring housing 52, back-moving spring 53 1 end bearings are in spring housing 52, the other end is bearing on the earmuff 2 and by back-moving spring positioning seat 55 location, button 41 is ball-type with spring housing 52 with the position that pressing plate 51 contacts.

Operation principle: when the user wears this earphone, to support 3 places behind the auricle and makes it be bearing in postauricular head place, therefore the chucking power that makes elasticity headband 1 act on the auricle is transferred to the head place via supporting 3, so both improve the comfortable wearing sense of earphone, do not influenced the audibility of earphone again.Because different user is variant on shape, size and the position of ear, therefore different users is also different to supporting 3 status requirement.For this reason, supporting 3 of the present utility model has increased the function that rotation is regulated.If the user thinks that comfort level is not enough after putting on earphone, can press the button 41, this moment, housing 40 interior pressing plates 51 changeed its jointed shaft 54 rotations, pressing plate 51 promotes spring housing 52 compression reseting springs 53 with button 41 contacted ends, positioning tooth 511 disengagings of pressing plate 51 other ends and cooperating of gear 31, but rotate so that support 3 driven gears 31, when the user thinks that earphone is worn in supporting 3 positions with can allowing own the most comfortable, release button 41, pressing plate 51 in the housing 40 is automatically reset under back-moving spring 53 effects, and make the positioning tooth 511 on the pressing plate 51 form engagement with gear 31, thereby gear 31 and the supporting that is connected with gear 31 3 is fixing, the part chucking power that elasticity headband 1 is produced can be transferred to postauricular head place to guarantee supporting 3.If the user does not want to use supporting 3 o'clock, can will support 3 opposite sides that forward earmuff 2 to by above method, make and support 3 and be not bearing on the head and get final product.

Embodiment 2: as shown in Figure 5, another kind of headphone of the present utility model, the control device 4 of this earphone are arranged on the elasticity headband 1 and by the housing 40 of control device 4 and fix with elasticity headband 1; Back-moving spring 53 1 end bearings in the elastic compression mechanism 5 in spring housing 52 and the other end be bearing on the elasticity headband 1, and by back-moving spring positioning seat 55 location of being located on the elasticity headband 1, in addition the internal structure of the concrete connected mode of the supporting in the present embodiment 3 and control device 4, control device 4 with and operation principle all identical with technique effect with embodiment 1.

In addition, used gear 31 also can be replaced with ratchet-gear wheel or friction pulley in the utility model, when using ratchet-gear wheel, the characteristic that can utilize ratchet-gear wheel is carried out automatic monodirectional locking to supporting 3 rotation, the user need adjust supporting 3 when the inboard rotation of earphone, does not need to press the button 41, directly stirs supporting 3 rotating side in earphone and gets final product,, when rotate in the earphone outside, press the button 41 earlier and adjust again in needs adjustment supporting 3; When using friction pulley, only need positioning tooth 511 changes of pressing plate 51 1 ends are got final product for forming the locating friction face that cooperates with friction pulley, this type of conversion all should be considered as the replacement that is equal to of the present utility model, all should drop within the protection range of the present utility model.
