It should be noted that：Similar label and letter represents similar terms in following accompanying drawing, therefore, once a certain Xiang Yi
It is defined, then it need not be further discussed in subsequent accompanying drawing in individual accompanying drawing.
The utility model provides a kind of earphone of this earphone rear shell of earphone rear shell and application.Earphone of the present utility model
In addition to including above-mentioned earphone rear shell, in addition to phonation unit, earphone fore shell, the earphone rear shell are fastened on earphone fore shell
After together, the cavity volume for accommodating sounding monomer is formd.
Sounding monomer can also use DYN dynamic sounding monomer with the sounding monomer of moving-iron type, or moving-iron type+dynamic
The sounding monomer of ring type.This belongs to the common knowledge of those skilled in the art, no longer illustrates herein.
After the sounding monomer is arranged in the cavity volume of earphone, the cavity volume is divided into the preceding operatic tunes isolated from one another, rear sound
Chamber, wherein, it is described after the operatic tunes towards the direction of earphone rear shell, the preceding operatic tunes is towards the direction of earphone fore shell.In order that earphone
The sound outflow sent, is additionally provided with sender etc., the structure of this earphone belongs to this area on the earphone fore shell
The common knowledge of technical staff, is no longer illustrated herein.
Referring to figs. 1 to Fig. 4, earphone rear shell of the present utility model includes rear shell body 1, and rear shell body 1 can use ability
Hemispherical known to field technique personnel or the cylindrical structural with one end open etc..The rear end of shell body 1 in the rear
Face sets fluted 3, and the first through hole 4, second for being separately provided for connecting the inner chamber of rear shell body 1 in the groove 3 is logical
Hole 5.It is provided with the screen cloth (view does not provide) for covering second through hole 5 in the position of second through hole 5, the screen cloth can be with
(inner side end of the second through hole 5) is arranged on the inwall of rear shell body 1, can also be arranged in groove 3 (the second through hole 5
End face outside) so that second through hole 5 can use as the sound regulating hole of earphone.The principle of sound regulating hole and the method for regulation are equal
Belong to the common knowledge of those skilled in the art, no longer illustrate herein.
In one preferred embodiment of the utility model, the rear end of the rear shell body 1 has the flange 2 heaved,
With reference to figure 2.Rear shell body 1 shown in Fig. 2 is in hemispherical, therefore for the ease of setting groove 3, each through hole, in rear shell body 1
Rear end forms the structure of a flange 2, and the flange 2 can be integrally formed with rear shell body 1 by way of injection.
The groove 3 is arranged on the end face of flange 2, and the first through hole 4, the second through hole 5 form the groove in flange 2
In 3, and it is connected together with the inner chamber of rear shell body 1.After the earphone rear shell is applied in earphone so that the rear operatic tunes of earphone
It can be connected together respectively by first through hole 4, the second through hole 5 with groove 3.Above-mentioned flange 2, groove 3, first through hole 4,
Second through hole 5 is formed when rear shell body 1 is molded, and is no longer illustrated herein.
End cap 7, the shape of the end cap 7 and the form fit of the end face of flange 2 are additionally provided with the rear end of rear shell body 1,
The two can be connected together by gluing.After the end face of the end cap 7 and flange 2 fits together, so as to by the groove 3 with
And first through hole 4, the second through hole 5 cover.The end cap 7 defines passage with the groove 3 on flange 2, and the passage leads to
Cross first through hole 4, the inner chamber of the second through hole 5 and rear shell body 1 is connected together.
Earphone rear shell of the present utility model, in addition to the connection groove 3 and extraneous third through-hole 6, with reference to figure 2, figure
3, the third through-hole 6 can be arranged in the side wall of flange 2, can also be arranged on end cap 7, so as to by groove 3 with it is extraneous
It is connected together.
Thus, the first through hole 4, groove 3, third through-hole 6 constitute bass tube passage；Second through hole 5, groove
3rd, third through-hole 6 constitutes tuning passage.That is, a sound wave part for the rear operatic tunes can pass through by first through hole 4, groove
3rd, the bass tube passage that third through-hole 6 is formed, so as to so that earphone has preferable low-frequency effect.Sound wave another part can be through
The tuning passage being made up of the second through hole 5, groove 3, the third through-hole 6 for being covered with screen cloth is crossed, so as to adjust in earphone
Yupin effect.
That is, the utility model earphone rear shell, third through-hole may act as the use of back cavity sound regulating hole, can also make
Used for bass pore so that back cavity sound regulating hole, bass pore can share a through hole.For the surface structure of earphone,
An only exposed through hole, makes the design of earphone more succinct, but tonequality does not reduce but in earphone rear shell.
In addition, for two exposed through holes are set in conventional earphone rear shell, earphone rear shell of the present utility model
An only exposed through hole, the waterproof effect of earphone can be improved.
First through hole 4 of the present utility model, the second through hole 5 can be separately positioned on the both ends of groove 3.With reference to figure 2, Fig. 3,
First through hole 4 is arranged on one end of groove 3, and the second through hole 5 can be arranged on the other end of groove 3, can so make full use of
The passage that groove 3 surrounds with end cap 7.
Further, the third through-hole 6 can be positioned adjacent to the position of the second through hole 5 so that third through-hole 6 and
The path of two through holes 5 is shorter.Such as the third through-hole 6 can be arranged on end cap 7 with the position of the face of the second through hole 5, or
Person is arranged on the position intersected in the side wall of flange 2 with the second through hole 5.Using such structure design so that tuning passage accounts for
Groove 3 is less, that is to say, that makes tuning passage short as far as possible, the sound wave of the rear operatic tunes can pass through the second through hole 5, the
Three through holes 6 are radiate.
In the utility model another preferred embodiment, the third through-hole 6 is positioned away from the second through hole 5
Position.Here, term " deviation " and above-mentioned " neighbouring " are comparatively, third through-hole 6 to be positioned away from into the second through hole 5
Position, this allow for tuning passage need take major part groove 3.Such as the third through-hole 6 can be arranged on end cap 7
On the upper position for deviateing the second through hole 5, or it is arranged on the position for deviateing the second through hole 5 in the side wall of flange 2.It should be noted
It is that third through-hole 6 can not be too near from first through hole 4, thus can ensure the length requirement of bass tube passage.
Earphone rear shell of the present utility model, because there is provided bass tube passage, it is no longer necessary to the bassoon in conventional earphone
Structure (earphone SR), therefore the structural volume of earphone can be reduced.
In order to ensure the bass effect of the utility model earphone, it is necessary to ensure the bass tube passage of sufficient length.When this reality
With new earphone rear shell volume it is larger when, the groove 3 can be on the end face of flange 2 along linear extension so that groove 3 is
The groove of one linear pattern extension.When earphone rear shell volume of the present utility model is smaller, the groove 3 can be at the end of flange 2
Extend on face along curve so that the groove that groove 3 extends for a shaped form, such as the those skilled in the art such as S-shaped, C-shaped institute are ripe
The regularly or irregularly curve shape known.
Although some specific embodiments of the present utility model are described in detail by example, this area
It is to be understood by the skilled artisans that above example merely to illustrate, rather than in order to limit the scope of the utility model.This
Field it is to be understood by the skilled artisans that can not depart from the scope of the utility model and spirit in the case of, to above example
Modify.The scope of the utility model is defined by the following claims.
