The present invention relates to field of mobile phones more particularly to a kind of earpiece and its use the mobile phone of the earpiece.
Background technique
With the rapid development of electronic technology, mobile phone has become the essential articles for daily use of people.For current
Mobile phone also has both other many additional functions other than with traditional communication function, one as mobile phone of earpiece
The height of important devices, quality directly affects the selection of user.
The mobile phone of the prior art has generally included earpiece and pcb board, the earpiece and pcb board be separately mounted to front housing with
In rear shell, which is fixed on front housing by double-sided adhesive.The earpiece has elastic slice, and the contact jaw of the elastic slice is Gold plated Layer, when
When flip lid, if there is opposite movement between front housing and rear shell, also there is opposite movement between such earpiece and pcb board.Therefore
The elastic slice of earpiece will lead to the Gold plated Layer abrasion that pcb board is contacted with earpiece, this mill in the pad friction with PCB many times
Damage to a certain extent, will directly result in pcb board and earpiece poor contact, not have sound so as to cause earpiece, reduce sound quality,
Functional influence is caused on the use of user；And and general clamshell phone require flip lid service life to reach 150,000 times, and
The clamshell phone of the prior art, which earpiece would generally occur after doing flip lid test tens of thousands of times, does not have the case where sound.
Therefore, the existing technology needs to be improved and developed.
Summary of the invention
The technical problem to be solved in the present invention is that in view of the above drawbacks of the prior art, provide a kind of earpiece and
It uses the mobile phone of the earpiece, can fundamentally avoid the friction between earpiece and pcb board, increase the reliable of clamshell phone
Property, effectively increase the acoustical quality of earpiece；And structure is simple, design is reasonable.
The technical proposal for solving the technical problem of the invention is as follows:
A kind of earpiece includes the headphone body in electrical contact with pcb board, be provided on the headphone body for
The positioning bar of locating slot cooperation fixation on pcb board.
As a preferred embodiment, the thickness of the positioning bar is smaller than the thickness of pcb board.

As a preferred embodiment, the gap size is 0.05mm.
As a preferred embodiment, the layers of two-sided for contacting with handset front case is provided on the headphone body.
It as a preferred embodiment, further comprise having foam, which is set between headphone body and layers of two-sided.
As a preferred embodiment, it is provided with the elastic slice being electrically connected with pcb board on the headphone body, is set on the elastic slice
It is equipped with strip salient point.
A kind of mobile phone includes front housing, rear shell, pcb board and earpiece, is provided with locating slot on the pcb board, the hand
The front end face of machine earpiece is connect with front housing, and the rear end face of the earpiece is connect with pcb board, which is inserted into fixed in locating slot
Position, the pcb board are fixed in rear shell.
It as a preferred embodiment, further comprise having display screen, the display screen and pcb board are electrically connected.
A kind of earpiece provided by the present invention, since which employs be provided with to be used for and pcb board on headphone body
On the fixed positioning bar of locating slot cooperation, the relative motion of headphone body and pcb board can be effectively prevent, to fundamentally keep away
Exempt from the friction between earpiece and pcb board, increases the reliability of clamshell phone, effectively increase acoustical quality；And it is arranged on elastic slice
There is strip salient point, instead of the round salient point on traditional technology, is more advantageous to the friction reduced between earpiece and pcb board, mentions
High tone quality, and the strip salient point can be molded with by mould punching, need to only be modified the shape of mold, will not be generated cost
Rising；In addition, having additional foam between headphone body and layers of two-sided, when front housing and rear shell generation relative motion, then
Foam meeting relative motion so that its connection is more stable, and is steeped so that headphone body will not move easily with pcb board
Cotton can also reduce impact of the front housing to earpiece when renovating test.

Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, right as follows in conjunction with drawings and embodiments
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
It please refers to shown in Fig. 1, a kind of earpiece, includes headphone body 1, which is electrically connected with pcb board 2
Touching.It is provided with positioning bar 3 on the headphone body 1, locating slot (showing in figure), the positioning bar 3 insertion are provided on the pcb board 2
It is positioned in locating slot, the relative motion of headphone body 1 Yu pcb board 2 can be effectively prevent.Locating slot on the positioning bar and pcb board 2
Between be formed with gap.Preferably, the gap size is 0.05mm.
