A cavity.The moving member is set in the side cavity of the horn single body sounding.Through-hole is offered in the rear shell,
The regulating part passes through the through-hole and drives moving member close to or far from the horn single body.
Preferably, connection is closed between the moving member and the shell.
Preferably, the moving member and the horn single body and the shell surround back cavity, are filled in the back cavity
Foam.
Preferably, the back cavity volume range is 50-300mm3。
Preferably, the foam is compressible foam.
Preferably, internal screw thread is equipped in the through-hole, the regulating part is equipped with outer spiral shell corresponding with the internal screw thread
Line.
Preferably, the through-hole is embedded with damping piece, and the damping piece, which encloses, is placed on the regulating part.
Preferably, the regulating part is abutted against or is fixedly connected with the moving member.
Preferably, one end of the front cover is fixedly connected with the horn single body, is provided in the other end of the front cover
Sound tube is provided with the pleasant gum cover of adaptation connection on the sound tube.
The beneficial effects of the utility model are: a kind of earphone provided by the utility model, opens up through-hole in earphone rear shell,
Regulating part passes through through-hole and drives moving member close to or far from horn single body, to change the size of back cavity, is emulated by vibration frequency
The size that curve graph can be seen that change back cavity can change the intensity of sound.It is big that user can adjust according to actual needs back cavity
It is small, switch the sound quality oneself liked at any time.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1 is the utility model Headphone structure explosive view；Fig. 2 is that the utility model earphone compresses when foam is uncompressed
Sectional view；Fig. 3 is that the utility model earphone compression foam is in the sectional view under compressive state；Fig. 4 is the utility model earphone

Specific embodiment:
As shown in Figure 1 to Figure 3, a kind of earphone provided by the utility model, including shell, horn single body 3, moving member 11,
Regulating part 12, shell are divided into front housing 4 and rear shell 1.In the receiving of horn single body 3 and shell, and the inner cavity of shell is divided into two
Cavity, the side that wherein horn single body 3 is spoken are ante-chamber.Moving member 11 is set in the side cavity of horn single body sounding,
It is connect with housings close, the moving member and horn single body and shell surround back cavity.The volume range of back cavity is 50-
300mm3, compressible foam 2 is filled in back cavity.
One end of front housing 4 is fixedly connected with horn single body 3, the other end of front housing 4 is provided with sound tube 41, in sound tube
The pleasant gum cover 5 of adaptation connection is provided on 41.
It is equipped with through-hole 13 in rear shell 1, internal screw thread is equipped in through-hole 13, regulating part 12 is equipped with opposite with 13 screw thread of through-hole
The external screw thread answered.Regulating part 12 is assemblied in through-hole 13, one end be equipped with revolving part, the other end drive moving member 11 close to or far from
Horn single body 3, when moving member 11 is close to horn single body 3, earphone back cavity becomes smaller；When moving member 11 is far from horn single body 3, after earphone
Chamber becomes larger.
In another embodiment, moving member 11 is set in the side cavity of 3 sounding of horn single body, and and shell
Body closing connection, is equipped with through-hole 13, through-hole 13 is embedded with damping piece, and damping piece, which encloses, is placed on regulating part 12 in rear shell 1.Regulating part
12 under damping action, can arbitrarily adjust the position of moving member 11, to adjust the size of back cavity, realizes the variation of sound quality.
It can be fixedly connected, can abut between moving member 11 and regulating part 12, revolving part can also be set on the two contact surface
Carry out assembly connection.
When regulating part 12 is fixedly connected with moving member 11, the revolving part on regulating part 12, the moving member in back cavity are rotated
11 rotate together.
When regulating part 12 abuts together with moving member 11, the pressure of the filling in horn single body 3, back cavity of moving member 11
Contracting foam 2 is compressed, and volume becomes smaller；When mobile toward the direction far from horn single body 3 when regulating part 12, moving member 11 is steeped by compression
The bounce of cotton 2 acts on, and is connected to always on regulating part 12.
The rotatable structure of bearing class can also be installed on moving member 11, when rotating the revolving part on regulating part 12,
Moving member 11 is not rotated with regulating part 12.
It can be seen that a kind of earphone provided by the utility model by all of above embodiment, by the way that regulating part band is arranged
Dynamic moving member is separate or close to horn single body, to control the size of adjustment earphone back cavity, as shown in figure 4, changing the size of back cavity
It can change being affected for the Mid Frequency of the intensity of sound, especially 1000-3000Hz.Therefore, user can according to oneself
Different demands are voluntarily adjusted, more convenient comfortable.
