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 mobile terminal.Mobile terminal in present embodiment is described for smart mobile phone, but present embodiment does not impose any restrictions mobile terminal particular type.As shown in Figure 1, 2, 3, this mobile terminal comprises: housing 1, sound chamber support 2, speaker body 3, circuit board 4 and radome 10.Housing in present embodiment is the back cover of mobile terminal.Sound chamber support 2 is fixed on housing 1, and a part 20 and the housing 1 of sound chamber support 2 form the first cavity, and speaker body 3 is positioned at the first cavity and speaker body 3 is installed on circuit board 4.21 another part of sound chamber support 2 and housing 1 form the rear sound chamber 5 of speaker body 3.Radome 10 is arranged at circuit board 4, and at least partly, the outside wall surface in sound chamber 5 is to radome 10.That is, this outer wall in rear sound chamber 5 and circuit board have predeterminable range, and this predeterminable range is not less than the height of this radome.
Sound chamber support 2 by gluing housing 1 or the ultra-sonic welded of being connected to of point in housing 1, can be sealedly and fixedly connected between the annular surface that namely sound chamber support contacts with housing.Thus, make, between sound chamber support and housing, there is good sealing, prevent loudspeaker from leaking sound.But present embodiment does not impose any restrictions for the fixed form of sound chamber support and housing.Mobile terminal also comprises first, second and the 3rd seal, and first, second and the 3rd seal all can adopt foam.Wherein, the first seal 7 is held between speaker body 3 and housing 1, and be surrounded on speaker body go out sound face.Second seal 6 is held between circuit board 4 and sound chamber support 2.Mobile terminal also comprises battery cover 9, housing 1 has opening, and opening goes out sound face corresponding to speaker body 3, and battery cover 9 has the sender 11 corresponding to opening, battery cover 9 is installed on housing 1, and the 3rd seal 8 to be held between housing 1 and battery cover 9 and to be surrounded on opening.Mobile terminal also comprises Air Filter, and what speaker body was located at by Air Filter goes out sound face.Thus going out between sound face, back cover and battery cover of speaker body forms front sound chamber, and front sound chamber and rear sound chamber keep apart by the first seal, prevent from, between forward and backward sound chamber, cross-talk occurs.Second seal prevents rear sound chamber from leaking sound, and the 3rd seal prevents front sound chamber from leaking sound.
Therefore, present embodiment in terms of existing technologies, due to the rear sound chamber by adopting sound chamber support the space between radome and back cover to be surrounded loudspeaker, makes the rear sound chamber of loudspeaker and radome be separated from each other, non-interference, further, after making loudspeaker, sound chamber and circuit board are separated.Thus, not only make the stack design after loudspeaker between sound chamber and radome very flexible, further increase the utilance of mobile terminal inner space, and reduce the complexity of mobile terminal indoor design, and circuit board can be reduced further, be conducive to reducing costs.
Second execution mode of the present utility model relates to a kind of mobile terminal.Second execution mode slightly improves on the basis of the first execution mode, and main improvements are: in this second embodiment, and mobile terminal also comprises detent mechanism, and sound chamber support is positioned housing by detent mechanism.
As shown in Figure 4, detent mechanism comprises the reference column (not shown) being located at housing, and sound chamber support 2 is provided with the location hole 22 corresponding to reference column.Reference column and location hole 22 can select suitable quantity according to actual needs, and in present embodiment, reference column and location hole 22 are respectively two.Thus, by location hole is sheathed on reference column, realizes sound chamber support and be accurately surely fixed on housing, not only easy to process, and can ensure between sound chamber and fixation between housing, good airproof performance.But only illustrate, the detent mechanism in present embodiment should as limit herein.
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.
