One side according to the present utility model provides a kind of earphone, including forms shell and the receiving of accommodation space
Accommodation space is separated into the preceding operatic tunes and the rear operatic tunes, institute by the loudspeaker monomer in the accommodation space, the loudspeaker monomer
Case inside surface before stating at the operatic tunes, which combines, is fixed with inner cover, and the loudspeaker monomer is fixed by inner cover and the shell to be connected
It connects, the inner cover is provided with operatic tunes internal protrusion forward with the protrusion of operatic tunes volume before reducing.
Preferably, the protrusion is set as integrally formed with inner cover side wall.
Preferably, operatic tunes internal bend convexes to form protrusion to the inner cover side wall forward.
Preferably, the inner cover side wall thickening convexes to form protrusion.
Preferably, the protrusion is in conjunction with the inner surface for being fixed on the inner cover.
Preferably, the protrusion is set as thin wall type structure, and surrounds cavity with the inner cover.
Preferably, the shell includes the front housing and rear shell of secure bond, and the inner cover is in conjunction with being fixed on the front housing
Inner surface, the loudspeaker monomer are fixedly connected by inner cover with the front housing.
Preferably, the front housing and it is interior cover corresponding section and be provided with let out acoustic aperture, described let out is covered with damping screen in acoustic aperture
Cloth.
Preferably, the damping screen cloth is arranged between the front housing and inner cover, and in conjunction with being fixed on the outer of the inner cover
Side surface.
The beneficial effects of the utility model are as follows:
The earphone of the utility model by being arranged the protrusion of operatic tunes internal protrusion forward in inner cover, to reduce the preceding operatic tunes
Volume improve the high frequency sound quality of earphone to make the high-frequency resonant point of earphone frequency response curve be in ideal interval.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 shows the sectional view of the utility model embodiment 1.
Fig. 2 shows the sectional views of the utility model embodiment 2.

Fig. 4 shows the sectional view of the utility model embodiment 4.
Specific implementation mode
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.
Embodiment 1:
In order to which the volume for solving the operatic tunes before earphone in the prior art is excessive, cause the high frequency sound quality of earphone is poor to ask
Topic, the utility model provides a kind of earphone, as shown in Figure 1, the earphone include secure bond front housing 1 together and rear shell 2,
And it is housed in the loudspeaker monomer 3 in the accommodation space that front housing 1 and rear shell 2 are collectively formed, loudspeaker monomer 3 is by accommodation space
It is separated into the preceding operatic tunes isolated from one another and the rear operatic tunes, wherein the preceding operatic tunes is towards the direction of front housing, and the rear operatic tunes is towards the side of rear shell
To.For the sound outflow for making earphone send out, sound outlet hole is additionally provided on front housing, this Headphone structure belongs to this field skill
The common knowledge of art personnel, no longer illustrates herein.The earphone of the utility model further includes combining to be fixed on 1 inside table of front housing
The inner cover 4 in face, loudspeaker monomer 3 are fixedly connected by inner cover 4 with front housing 1.Inner cover 4 is provided with towards protrusion inside the preceding operatic tunes
Protrusion 41, protrusion 41 can play the role of operatic tunes volume before reducing, pass through under the premise of not changing original earphone shape
The volume of the operatic tunes makes the high-frequency resonant point of earphone frequency response curve be in ideal interval before reducing, to improve the high frequency audio of earphone
Matter.
