Embodiment

In order to illustrate more clearly of the utility model, the utility model is done into one with reference to preferred embodiments and drawings The explanation of step.Similar component is indicated with identical reference numeral in attached drawing.It will be appreciated by those skilled in the art that below Specifically described content is illustrative and be not restrictive, and should not limit the scope of protection of the utility model with this.

The utility model provides a kind of headphone, and as shown in Figs 1-4, which includes：Headband 1 and ear Shell 2, it is generally the case that headphone includes two auricular conchas 2, and two auricular conchas 2 are fixedly connected on the both ends of headband 1.City at present Also there is a kind of headphone that an auricular concha 2 is fixedly connected with one end of headband 1 on field, the utility model does not limit this Fixed, those skilled in the art can make choice according to actual needs.

As shown in Figs. 1-2, the end of headband 1 stretches out to form plug division 11, and plug division 11 is hollow cylinder, its End surface convexes to form the bayonet 12 of annular shape, offers escape groove 13 along the axial direction of plug division 11, the end face of bayonet 12 is set The first chamfering 14 is equipped with, the side end face of bayonet 12 is provided with the second chamfering 15.Escape groove 13 is by 12 equipartition of bayonet into two Point.As shown in Figure 3-4, auricular concha 2 is the cylindrical form with accommodating chamber, and loudspeaker is fixed in accommodating chamber.Auricular concha 2 Side wall on offer spliced eye 21, the inner surface of spliced eye 21 convexes to form the boss 22 of annular.Using the above structure Headphone, headband 1 and auricular concha 2 are two independent structures, it is necessary to when being assembled into finished product, it is only necessary to are inserted into plug division 11 Spliced eye 21 can be completed to assemble.When spliced eye 21 is inserted into plug division 11, plug division 11 is in the first chamfering 14 and boss 22 Interaction under, in gradual necking deformation insertion spliced eye 21, escape groove 13 provides the deformation space of plug division 11, and second falls Angle 15 can avoid two parts interference and collision of buckle 12 so that plug division 11 is easily inserted into spliced eye 21, so that headband 1 It is simple for assembly process with auricular concha 2.Further, auricular concha 2 includes the upper shell and lower housing shell for being collectively forming accommodating chamber, upper shell Mutually fasten and be fixed by screw with lower housing shell.Spliced eye 21 is opened on lower housing shell, improves the company of headband 1 and auricular concha 2 Connect reliability.

Further, the end face outside of boss 22 is additionally provided with the 3rd chamfering so that plug division 11 can be from spliced eye 21 Extract, so that headband 1 becomes detachable structure with auricular concha 2.

As shown in Figure 1, the end of headband 1 is additionally provided with damping ring 16, the material of damping ring 16 is soft rubber material, resistance Buddhist nun's ring 16 is integrally formed with headband 1, and in the present embodiment, the material of damping ring 16 is silicon rubber.When plug division 11 and spliced eye 21 After grafting combines, auricular concha 21 is in close contact with damping ring 16, after damping ring 16 is deformed, increases auricular concha 21 and damping ring 16 Between frictional force, increase rotation auricular concha 21 when damping, improve feel.

As shown in Figure 1, the outer surface of plug division 11 convexes to form rotation prevention portion 17.As shown in figure 4, the inner side of spliced eye 21 Surface bulge forms block 23, the relative rotation angle caused between auricular concha 2 and headband 1 corresponding with the matching of block 23 of rotation prevention portion 17 Less than or equal to 90 degree.It can rotate against between headband 1 and auricular concha 2, be adjusted easy to the head dummy according to user, meanwhile, Auricular concha 2 can also be avoided excessively to be rotated with headband 1, the connecting line for making it internal is damaged.

Further, fluted 18 are opened up on plug division 11, when plug division 11 is inserted into spliced eye 21, boss 22 In groove 18, the connection reliability of headband 1 and auricular concha 2 is improved.

Obviously, above-described embodiment of the utility model is only intended to clearly illustrate the utility model example, and It is not the restriction to the embodiment of the utility model, for those of ordinary skill in the field, in described above On the basis of can also make other variations or changes in different ways, all embodiments can not be exhaustive here, It is every to belong to obvious changes or variations that the technical solution of the utility model is extended out still in the utility model The row of protection domain.
