Accompanying drawing explanation
Fig. 1 is the profile of the earpiece module according to the utility model first execution mode;
Fig. 2 is according to the schematic internal view of listening cylinder shell in the utility model first execution mode.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, each execution mode of the present utility model is explained in detail.But, persons of ordinary skill in the art may appreciate that in each execution mode of the utility model, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following execution mode and amendment, each claim of the application technical scheme required for protection also can be realized.
First execution mode of the present utility model relates to a kind of earpiece module, is applied to mobile terminal, such as mobile phone.As shown in Figure 1, 2, earpiece module 1 at least comprises and listens cylinder shell 10, headphone body 11, circuit board 12 and sealant 13.
Listen cylinder shell 10 to be formed with cavity 101, headphone body 11 is installed on the circuit board 12 and is positioned at cavity 101.Listen cylinder shell 10 to have the first sender 102 corresponding to headphone body 11, this first sender 102 runs through this listens cylinder shell 10.That is, headphone body 11 is positioned at cavity 101, and sound is passed on away from the first sender 102.Wherein, headphone body 11 such as can utilize reference column 103 to be positioned circuit board 12.
In present embodiment, listen cylinder shell 11 to have the cavity wall forming cavity 101, be respectively upper side wall 101-1, lower wall 101-2 and the left side wall 101-3 and right side wall 101-4 of cavity 101.Wherein, upper side wall 101-1, left side wall 101-3, right side wall 101-4 have phase co-altitude (due to technique, also may have small difference in height, but can think be in sustained height level); And lower wall 101-2 is lower compared with other three side.Therefore, when circuit board 12 be arranged on listen on cylinder shell 11 time, one side surface of circuit board 12 is held in upper side wall 101-1, left side wall 101-3 and right side wall 101-4 substantially, and the lower wall 101-2 of cavity 101 is away from the surface of circuit board 12, namely cavity 101 is communicated in circuit board 12 and the underlying space listening cylinder shell 10 to be formed by its lower wall 101-2, thus make the rear sound chamber of receiver infinitely great, with the needs of satisfied reception and registration sound (if do not have rear sound chamber to lack low frequency, sound effect becomes sharp-pointed).It should be noted that, because circuit board and cavity wall are all be made up of hard material (such as plastics), therefore, although a side surface of circuit board 12 is held in upper side wall 101-1, left side wall 101-3 and right side wall 101-4 substantially, this side surface of circuit board and also blow-by between upper side wall 101-1, left side wall 101-3 and right side wall 101-4.
Sealant 13 is arranged between part cavity wall and circuit board 12, and in present embodiment, part cavity wall is upper side wall 101-1, left side wall 101-3 and right side wall 101-4.That is, part cavity wall and circuit board 12 are tightly connected by sealant 13; Wherein, sealant 13 be "
" foamed cotton layer of type structure.But the concrete shape of present embodiment to sealant 13 does not impose any restrictions, sealant can design according to the concrete shape of part cavity wall.Further, sealant also can be other elastic material.
Specifically, first, incite somebody to action "
" type foam is fixed on three cavity walls (i.e. upper side wall 101-1, left side wall 101-3 and right side wall 101-4), such as, the mode pasted can be adopted to fix; Or, also can by "
" type foam fixes the region of these three sidewalls corresponding to cavity on circuit boards.Then, be assembled in by the circuit board 12 being provided with headphone body 11 and listen cylinder shell 10, now, headphone body 11 is positioned at cavity, the surface of circuit board 12 by should "
" type foam and three cavity walls combine closely.That is, headphone body 11 by semitight in cavity 101 (except the lower wall 101-2 of cavity 101 is in communication with the outside).Thus, can prevent by listening on the upside of cylinder shell 10, dust that left side and right side enter or moisture or salt fog invade headphone body 11.
Preferably, the earpiece module 1 in present embodiment also comprises Air Filter 14, and Air Filter 14 is arranged on the outer surface and covering the first sender 102 of listening cylinder shell 10.Thus, can prevent the dust entered from the first sender 102 from invading headphone body 11.
Preferably, earpiece module 1 in present embodiment also comprises the eyeglass 15 being arranged on the outer surface listening cylinder shell 10, eyeglass 15 is provided with the second sender 151 in the position corresponding with the first sender 102, and the area of the second sender 151 is less than the area of the first sender 101.Eyeglass 15 can make earpiece module 1 have larger intensity and better sense of touch.Further, eyeglass 15 can cover the edge of Air Filter, to make to be fixed on Air Filter 14 difficult drop-off listening cylinder shell 10.
Second execution mode of the present utility model relates to a kind of earpiece module.Second execution mode is roughly the same with the first execution mode, and main distinction part is: in the first embodiment, and sealant is foamed cotton layer.And in the utility model second execution mode, sealant is sealant layer.Specifically, circuit board is fixed on after listening cylinder shell, sealant layer is applied at these three sidewalls (upper side wall, left side wall, right side wall) of cavity and the contact position of circuit board, thus, dust, moisture and salt fog can be stoped to invade headphone body from these three sidewalls of cavity.
The utility model the 3rd execution mode relates to a kind of mobile terminal, and mobile terminal is such as mobile phone.Mobile terminal comprises: procapsid, back casing and the earpiece module described in the first or second execution mode.Please refer in the first execution mode as Fig. 2, in present embodiment, the cylinder shell 10 of listening of earpiece module is the procapsid of mobile phone, the back casing of mobile phone (not shown) can be covered on procapsid to form a complete phone housing, wherein, headphone body and circuit board are all positioned at this phone housing.Wherein, the procapsid bossed housing position of bone of tool in fact of mobile phone, cavity 101 is the space formed by the housing position of bone, that is, the housing position of bone of handset front case body defines cavity wall.
Persons of ordinary skill in the art may appreciate that the respective embodiments described above realize specific embodiment of the utility model, and in actual applications, various change can be done to it in the form and details, and do not depart from spirit and scope of the present utility model.
