Acoustic aperture, 7, main acoustic aperture screen cloth, the 8, first groove, the 9, second groove.
Identical label indicates similar or corresponding feature or function in all of the figs.
Embodiment
The problem of sealing uniformity is bad be present for the component sealing means of the existing earphone fore shell of foregoing proposition, from
And causing headphone acoustic performance bad, the utility model provides a kind of new earphone fore shell, by between inner cap and protecgulum
Increase foam reaches the purpose of inner sealing lid and protecgulum, and ensure main acoustic aperture and before let out acoustic aperture will not be by inner cap and protecgulum
Gap gang up, so as to reach the consistent purpose of acoustical behavior.
Specific embodiment of the utility model is described in detail below with reference to accompanying drawing.
In order to illustrate earphone front casing structure provided by the utility model, Fig. 1 is shown according to the utility model embodiment
Earphone front casing structure schematic diagram.
As shown in figure 1, the utility model proposes earphone fore shell, including protecgulum 1 and with the dispensing of protecgulum 1 fix inner cap 2；
Wherein, on protecgulum 1 and inner cap 2 it is corresponding be provided with before let out acoustic aperture 4, be disposed with from outside to inside on acoustic aperture 4 is preceding let out
Acoustic aperture screen cloth 5 and foam 3 are let out, and lets out acoustic aperture screen cloth 5 and foam 3 between protecgulum 1 and inner cap 2；Wherein, acoustic aperture screen cloth is let out
4 between protecgulum 1 and inner cap 2 close to the side of protecgulum 1, foam 3 positioned at protecgulum 1 and inner cap 2 between close inner cap 2 one
Side.
Specifically, it is preceding let out acoustic aperture 4 be used for balance ante-chamber (i.e.：The loudspeaker monomer of earphone fore shell and earphone forms earphone
Ante-chamber) inner and outer air pressure, prevent vibrating diaphragm because front and rear air pressure not etc. caused by vibrating diaphragm bulging or recessed contracting.Set on acoustic aperture 4 is preceding let out
Let out acoustic aperture screen cloth 5 be used for prevent the external world dust or particle enter ante-chamber inside.
In embodiment of the present utility model, let out acoustic aperture screen cloth 5 and foam 3 is arranged between protecgulum 1 and inner cap 2, i.e.,：Let out
Acoustic aperture screen cloth 5 and foam 3 are located at the intersection that protecgulum 1 interfixes with inner cap 2.That is, it is provided with first on protecgulum 1
Groove 8, let out acoustic aperture screen cloth 5 and be housed in the first groove 8；The dispensing in the first groove 8, let out before the dispensing of acoustic aperture screen cloth 5 is fixed on
On lid 1.
Wherein, in embodiment of the present utility model, it is recessed that second corresponding with the first groove 8 is provided with inner cap 2
Groove 9, foam 3 are housed in the second groove 9；In the second groove 9 and the dispensing of acoustic aperture screen cloth 5 is being let out, the dispensing of foam 3 is fixed on interior
Second groove 9 of lid 2 and let out between acoustic aperture screen cloth 5.
, wherein it is desired to explanation, the first groove 8 in protecgulum 1, is housed in letting out on acoustic aperture screen cloth 5 in first groove 8
Dispensing, and the dispensing in the second groove 9 of inner cap 2, foam 3 are tightly fixed to the first groove 8 and by glue for dispensing glue
In two grooves 9, i.e.,：Together with protecgulum 1 is fixed by foam 3 with inner cap 2, that is to say, that protecgulum 1 can by foam 3
Reach the effect of sealing with inner cap 2.
In addition, in embodiment of the present utility model, it is corresponding on protecgulum 1 and inner cap 2 to be provided with main acoustic aperture 6,
Main acoustic aperture screen cloth 7 is provided with main acoustic aperture 6, and main acoustic aperture screen cloth 7 is between protecgulum 1 and inner cap 2.Wherein, main acoustic aperture 6 is used
It is connected in ante-chamber with the external world, before the main acoustic aperture screen cloth 7 that main acoustic aperture 6 is set is used to avoid extraneous dust or particle entrance
Intracavitary portion.
Sealed and fixed by the dispensing of foam 3 in embodiment of the present utility model, between protecgulum 1 and inner cap 2, can avoided
Main acoustic aperture 6 and preceding acoustic aperture 4 of letting out are ganged up by the gap between protecgulum 1 and inner cap 2, so as to reach the consistent of headphone acoustic performance
Property.
Earphone fore shell provided by the utility model can be seen that by above-mentioned embodiment, by protecgulum and inner cap it
Between foam enhancing cotton, strengthen the sealing between protecgulum and inner cap, and main acoustic aperture can be ensured and before let out acoustic aperture will not pass through inner cap
Ganged up with the gap of protecgulum, so as to improve headphone acoustic performance and uniformity.
Described in an illustrative manner above with reference to accompanying drawing according to the utility model proposes earphone fore shell.But ability
Field technique personnel should be appreciated that the earphone fore shell proposed for above-mentioned the utility model, can also not depart from this practicality newly
Various improvement are made on the basis of type content.Therefore, the scope of protection of the utility model should be by appended claims
Content determines.
