技术领域
本公开涉及移动终端设计技术领域，尤其涉及一种移动终端。
背景技术
移动终端(例如手机)已经成为人们生活中不可或缺的一部分，目前的移动终端功能较多，而通话功能则是移动终端的基本功能之一。受话器是实现通话功能的基本构件。受话器安装在移动终端的内腔之中，受话器包括电线圈和固定在电线圈上的振膜，在工作的过程中，电线圈在磁场中受到洛伦兹力时会带动振膜振动，振膜的振动会推动空气振动，进而产生声音。
通常情况下，受话器布设在移动终端内腔的顶部，受话器的振膜正面朝向移动终端的受话器前腔，背面朝向受话器后腔。受话器前腔与受话器后腔密封隔离。在振膜振动的过程中，振膜的正面会推动受话器前腔中的空气，进入从移动终端的出声孔中传出声音。振膜的背面同样会推动受话器后腔中的空气。受话器后腔中的空气受到振动后会提高受话器的低频效果，受话器的低频效果会对受话器的听感产生较大影响，低频的缺失会使得受话器发出的声音听起来刺耳而不柔和。
我们知道，受话器后腔的等效声容越大，受话器的低频效果就越好，而受话器后腔的等效声容会受到受话器后腔体积的影响。但是，目前的移动终端普遍向着轻薄化的方向发展，这使得受话器后腔的体积变得越来越小，进而会导致受话器后腔的等效声容越来越小。很显然，这无疑会影响移动终端的受话器的低频性能。
发明内容
本公开公开一种移动终端，以解决目前的移动终端的受话器的低频效果较差的问题。
为了解决上述问题，本公开采用下述技术方案：
一种移动终端，包括具有内腔的外壳和设置在所述内腔中的受话器，所述内腔包括相互隔离的受话器前腔和受话器后腔，所述受话器前腔和所述受话器后腔在所述受话器的振膜振动方向上分别位于所述受话器前后两侧，所述外壳上开设有与所述受话器前腔连通的第一出音孔，所述外壳上开设有与所述受话器后腔连通的第二出音孔。
本公开采用的技术方案能够达到以下有益效果：
本公开公开的移动终端中，外壳上开设有第二出音孔，第二出音孔能够连通受话器后腔与外界环境，进而能增加受话器后腔内空气的流动性，最终能提高受话器后腔的等效声容，达到优化其低频效果的目的。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合本公开具体 实施例及相应的附图对本公开技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
以下结合附图，详细说明本公开各个实施例公开的技术方案。
请参考图1-图4，本公开实施例公开一种移动终端，所公开的移动终端包括外壳100和受话器200。
外壳100是移动终端的外围壳体，外壳100具有内腔110，内腔110用于为移动终端的其它组成部分提供安装空间。受话器200设置在外壳100的内腔110中。通常，受话器200通过连接结构或连接件固定在外壳100的内腔110中。
内腔110包括受话器前腔111和受话器后腔112，受话器前腔111和受话器后腔112相互隔离。受话器前腔111和受话器后腔112在受话器200的振膜振动方向上分别位于受话器200的前后两侧。受话器前腔111和受话器后腔112通过安装在内腔110中的其它构件实现密封隔离。
需要说明的是，所述的受话器前腔111指的是受话器200的正面(设置振膜的一侧表面)面对的空腔，受话器后腔112指的是受话器200的背面面对的空腔。当然，受话器的振膜的振动能够实现受话器前腔111和受话器后腔112内的空气发生扰动。
外壳100上开设有第一出音孔，第一出音孔连通受话器前腔111与外界环境。外壳100上还开设有第二出音孔，第二出音孔连通受话器后腔112与外界环境。
在移动终端越来越轻薄化的当前，受话器后腔112的体积越来越小，这会导致受话器后腔112的等效声容变小，进而会导致受话器200的低频效果较差，本公开实施例公开的移动终端中，外壳100上开设有第二出音孔，第二出音孔能够连通受话器后腔112与外界环境，进而能增加受话器后腔112内空气的流动性，最终能提高受话器后腔112的等效声容，达到优化其低频效果的目的。
本公开实施例公开的移动终端绕开通过增加受话器后腔112的体积来增 加等效声容的方法，通过提高受话器后腔112内空气的流动性来提升等效声容，能够确保受话器后腔112维持较小的体积，在不影响低频效果的基础上，更有利于移动终端的轻薄化设计。
当然，在实际的工作过程中，受话器200工作产生的声音通过第一出音孔传出，同时，第二出音孔也能传出声音，很显然，这能够使得移动终端的两侧都成为出音侧，这无疑会更方便用户的使用。
为了提高受话器后腔112内空气受驱动后的流动效果，可选的方案中，第二出音孔可以设置在外壳100上与受话器200的背侧相对的部位上。此种情况下，受话器200的振膜振动时能够更有利于受话器后腔112内空气从第二出音孔流出。具体地，第二出音孔的数量可以为至少两个，至少两个第二出音孔均匀分布，进而能更优化空气流动效果。
在实际的工作过程中，第一出音孔和第二出音孔分别需要与受话器前腔111和受话器后腔112连通，而受话器前腔111和受话器后腔112则位于移动终端中，为了避免对内腔110内其它部件的影响，第一出音孔和第二出音孔均设置有防尘部件。具体地，防尘部件可以为防尘网或防水透气膜。
如上文所述，形成受话器前腔111和受话器后腔112的方式有多种。本公开实施例中，外壳100可以包括中框120和设置在中框120的顶端的第一屏幕盖板130，内腔110中安装有主板上盖160，主板上盖160用于安装移动终端的主板，当然也可以为安装移动终端的其它部件。受话器200安装在主板上盖160上，受话器200、主板上盖160、中框120和第一屏幕盖板130围成受话器前腔111，第一屏幕盖板130上开设有第一出音孔。上述结构能够充分利用移动终端已有的部件实现受话器前腔111的形成。
第一屏幕盖板130通常为玻璃盖板。为了提高装饰效果，第一屏幕盖板130可以包括第一受话器装饰罩131，第一受话器装饰罩131开设有第一出音孔。此种第一出音孔开设在第一受话器装饰罩131上，能够较好地确保移动终端的外观性能。
在上述结构外壳100的基础之上，外壳100还可以包括电池盖140，电池盖140、中框120、主板上盖160和受话器200围成受话器后腔112，电池盖140上开设有第二出音孔141。
当然，移动终端的结构不同，形成受话器后腔112的部件有所差异，外壳100还可以包括第二屏幕盖板150，第二屏幕盖板150、中框120、主板上盖160和受话器200围成受话器后腔112，第二屏幕盖板150上开设有第二出音孔152。此种情况下，移动终端通常为双屏移动终端，而且上述第二出音孔152的布设，能够更适应双面操控设备的通话。
同理，第二屏幕盖板150上可以包括第二受话器装饰罩151，第二受话器装饰罩151开设有所述第二出音孔152。
为了实现防水，电池盖140或第二屏幕盖板150与受话器200之间可以设置有防尘网300，防尘网300可以覆盖在第二出音孔141或第二出音孔152上。
受话器200为相关技术中的零部件，其前侧的防水性能较好，但是后侧的防水性能较弱，因此需要为受话器200的后侧提供更好的防水件。基于此，可选的方案中，电池盖140或第二屏幕盖板150与受话器200之间可以设置有防水透气膜，防水透气膜不允许水通过，但是可以透气，确保发声过程中空气的流动不受影响。防尘网300和防水透气膜可以直接通过胶水粘接在电池盖140或第二屏幕盖板150上。
本公开实施例公开的移动终端还可以包括弹性垫400，弹性垫400布设在受话器200的背侧边缘、且与防尘网300或防水透气膜固定连接，防尘网300或防水透气膜与弹性垫400夹固在电池盖140或第二屏幕盖板150与受话器200之间。弹性垫400具备较好的弹性，在移动终端组装完成之后，弹性垫400被压紧，进而间接实现防尘网300得到更稳定地安装。
在具体的实施过程中，弹性垫400与防尘网300或防水透气膜可以通过胶水粘接形成整体，所形成的整体被夹紧固定在电池盖140或第二屏幕盖板150与受话器200之间。当然，弹性垫400与防尘网300或防水透气膜形成的整体的一侧可以预先与受话器200粘接固定，另一侧被电池盖140或第二屏幕盖板150压紧。或者，弹性垫400与防尘网300或防水透气膜形成的整体的一侧可以预先与电池盖140或第二屏幕盖板150粘接固定，另一侧被受话器200压紧。
如图4所示，本公开实施例公开的移动终端还可以包括密封圈500(或 密封圈500’)，密封圈500设置在受话器后腔112中、且环绕设置在受话器200之外。密封圈500环绕在受话器200之外，能够减小受话器后腔112的空间，使得受话器后腔112中的空气在振膜振动时全部被排出，该方案同样能够减小从第一出音孔出来的声音与从第二出音孔出来的声音的差异，进而使得移动终端的两侧的听感一致。当然，密封圈500的设置还能起到密封防护受话器200的作用，避免从中框120与电池盖140对接处进入到受话器后腔112内的水、灰尘对受话器200的影响。
一种具体的实施方式中，弹性垫400和密封圈500均可以是泡棉件，弹性垫400无需密封，密封圈500则起到密封的作用。弹性垫400主要起到安装防尘网300或防水透气膜的作用，弹性垫400的布设不会阻隔其与弹性垫400之间的空间与第二出音孔的连通。
本公开实施例公开的移动终端可以是手机、平板电脑、可穿戴设备等，本公开实施例不限制移动终端的具体种类。
本公开上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本公开的实施例而已，并不用于限制本公开。对于本领域技术人员来说，本公开可以有各种更改和变化。凡在本公开的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本公开的权利要求范围之内。
