Embodiment

In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model is further introduced and explanation, but be not limited to this.

To shown in Figure 5, a kind of Supra-aural headphone structure of the utility model comprises headband 10 and two ear casings 20 that connect with headband 10 two ends such as Fig. 1, and ear casing 20 and headband 10 are for being actively coupled.

Headband 10 comprises headband body 11, and be located at the travelling arm 12 at headband body 11 two ends, what the outer end of travelling arm 12 was provided with the cuboid lug boss 13 that is embedded in the ear casing 20 and was used for linkage rectangle body lug boss 13 and travelling arm 12 connects neck 14, consists of being actively coupled of ear casing 20 and headband 10 with this.The advantage of cuboid lug boss is to have enough linking intensities, and can be complementary with the ear casing of flat, can not increase the physical dimension of ear casing.

Headband 10, its two ends are provided be used to the chute 15 that holds travelling arm 12.What headband 10 adopted in the present embodiment is split-type structural, and namely the two ends of headband body 11 are fixed with chute box 16, and chute box 16 inboards are provided with described chute 15.Travelling arm 12 is split-type structural also, comprises travelling arm shell 121 and the steel band 122 of being located in the travelling arm shell 121.Travelling arm shell 121 inboards are provided with positioning convex section 123; Chute 15 bottoms are provided with several projections 151, and projection 151 is two rows and distributes (position of positioning convex section design in the middle of two row's projections can be conducive to reduce the deflection when sliding like this, reduce thus the strength of required use when sliding); When use procedure, positioning convex section 123 can only place between the projection 151, can make positioning convex section 123 slip over the surface of projection 151 by larger external force, realize the adjusting of band size, and without External Force Acting the time, maintain static between travelling arm and the headband body, be difficult for sliding.Travelling arm adopts split-type structural, helps to guarantee that it has certain structural strength, helps it to have certain surface toughness, helps to realize that the button type orientation assemble with chute concerns.

Ear casing 20, its limit, upper end is provided be used to the cavity 21 that holds cuboid lug boss 13, and the upper end of cavity 21 is provided with and the flange part 22 that connects neck 14 and cooperate; Be provided with the space for 13 deflections of cuboid lug boss in the cavity 21, flange part 22 is provided with for the space that connects neck 14 deflections.In the present embodiment, ear casing 20 adopts split-type structural, it comprises shell body 20A and the inner housing 20B that is fixedly connected with shell body 20A, the upper end of shell body 20A is provided with outer half 21A of of cavity and outer half 22A of of flange, and the upper end of inner housing 20B is provided with half 21B of and interior half 22B of of flange in the cavity.In the present embodiment, the leading portion of outer half 22A of of flange partly is provided with triangular open space 221A, the back segment of half 22B of partly is provided with triangular open space 221B in the flange, (and cavity adopts larger size to consist of the space of aforesaid flange part, give the cuboid lug boss enough activity spaces), realize connecting the deflection of neck 14 with this, also be that ear casing can be realized the deflection with headband, but except having deflectable gap, the fit-up gap that does not have other, giving the good experience of user, use and the process such as transportation in all can not produce loosening or abnormal sound.Wherein, inner housing 20B is provided with several senders 29.(being between shell body 20A and the inner housing 20B) is provided with loud speaker 30(and is fixed on the shell body 20A in ear casing 20).

In other embodiment, headband also can adopt the single formula structure that does not have travelling arm.

In other embodiment, travelling arm also can adopt monolithic construction.

In sum, the utility model adopts has the cuboid in space and the connecting mode of cavity, its space can make about 15 °～20 ° of ear casing deflections, head is upper just to solve the angle of automatically regulating ear casing as long as be applied to, make itself and human body ear properer, do not have the sensation of pressing ear yet, promoted the comfortableness of wearing.The utility model has also further adopted the travelling arm structure, can be according to the direct manual adjustments of head of different sizes.The utility model adopts has cuboid and the connecting mode of cavity and the structure of travelling arm in space, simple in structure, easily processing, and production cost is low.

Above-mentionedly only further specify technology contents of the present utility model with embodiment; so that the reader is more readily understood; but do not represent execution mode of the present utility model and only limit to this, any technology of doing according to the utility model is extended or recreation, all is subjected to protection of the present utility model.Protection range of the present utility model is as the criterion with claims.
