此处的附图被并入说明书中并构成本说明书的一部分，示出了符合本申请的实施例，并与说明书一起用于解释本申请的原理。
具体实施方式
为了更好的理解本申请的技术方案，下面结合附图对本申请实施例进行详细描述。
应当明确，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
应当理解，本文中使用的术语“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
需要注意的是，本申请实施例所描述的“上”、“下”、“左”、“右”等方位词是以附图所示的角度来进行描述的，不应理解为对本申请实施例的限定。此外，在上下文中，还需要理解的是，当提到一个元件连接在另一个元件“上”或者“下”时，其不仅能够直接连接在另一个元件“上”或者“下”，也可以通过中间元件间接连接在另一个元件“上”或者“下”。
随着便携式电子设备技术的发展，人们对便携式电子设备(例如笔记本电脑)的外放音效要求越来越高。为了提升笔记本电脑的低频频响，笔记本电脑的微型扬声器的振幅设计越来越大。然而，在微型扬声器大振幅应用下，微型扬声器音圈和振膜的震动会激励键盘震动，影响用户使用键盘的体验，而且会产生杂音影响外放的音质。相关技术中，通常是通过降低扬声器音圈振幅的方法来降低键盘的震动，但是会同时降低了低频响度，牺牲音效。
如图1所示，为了解决上述技术问题，本申请实施例提供了一种便携式电子设备。在一些实施方式中，该电子设备可以是笔记本电脑200，当然还可以是其它电子设备，例如平板电脑、手机等，在此本申请对其不进行穷举。
在本实施方式中，该笔记本电脑200包括主体210、屏幕220和设置于主体210上的键盘230，扬声器模组100设置于主体210的内部。主体210内设置有电路板(图中未示出)，扬声器模组100与电路板电连接，以使电路板向扬声器模组100传递电信号，进而通过扬声器模组100发出声音。
在一些实施方式中，扬声器模组100可以设置于主体210上键盘230的一侧任意位置，例如可以是如图1所示的键盘230上部(如虚线所示)。相关技术中，扬声器模组通常包括壳体和收容在壳体内的一个扬声器单体，扬声器单体的振膜在震动时所产生的反作用力会导致扬声器单体的震感明显， 进而带动震动，具有该扬声器模组的电子设备出现异响杂音，影响用户的使用体验，本申请实施例提供的扬声器模组100能够较好地解决上述技术问题。
如图2所示，本申请实施例提供了一种扬声器模组100，该扬声器模组100包括第一扬声器单体21和第二扬声器单体22(可参见图2)，第一扬声器单体21和第二扬声器单体22工作时振膜震动的方向相反，如此可使扬声器模组100的动量变化Δ(mv)相互抵消，从而可以保证对笔记本电脑200的震动激励较小甚至无震动激励。如此设置，在扬声器模组100播放声音且用户使用键盘230时，扬声器模组100对主体210和键盘230的震动影响会大大减小，进而不仅可以提高用户的使用体验，还能提高笔记本电脑200外放的音效质量。
下面对扬声器模组100进行描述。
实施例一
如图2所示，其为本申请实施例一提供的扬声器模组100的分解示意图。如图3所示，其为本申请实施例一提供的扬声器模组100的剖面示意图。请参阅图2和图3，该扬声器模组100包括第一扬声器模组10和第二扬声器模组20，第一扬声器模组10包括第一壳体11和收容于第一壳体11内的第一扬声器单体21，第一扬声器单体21具有第一振膜211，第二扬声器模组20包括第二壳体12和收容于第二壳体12内的第二扬声器单体22，第二扬声器单体22具有第二振膜221。
第一扬声器模组10和第二扬声器模组20沿竖直方向Y依次设置，例如可以是第一扬声器模组10设置于第二扬声器模组20的上方。可以理解的是，第一扬声器模组10可以设置于第二扬声器模组20的正上方(例如图4)，第一扬声器模组10还可以设置于第二扬声器模组20的斜上方(例如图3、图5和图6)。
在本实施方式中，第一扬声器模组10和第二扬声器模组20反向设置，具体可以是第一振膜211和第二振膜221反向设置，即第一振膜211震动的方向F1和第二振膜221震动的方向F2相反，如此可使扬声器模组100的动量变化Δ(mv)相互抵消，从而可以保证对具有该扬声器模组100的便携式电子设备的震动激励较小甚至无震动激励。
如图7所示，其为本申请实施例一、三和四提供的扬声器模组100的力分析示意图。当第一扬声器模组10设置于第二扬声器模组20的斜上方时，扬声器模组100沿振膜震动的方向的力相抵消，只残留旋转方向的应力，经过验证，对具有该扬声器模组100的便携式电子设备的震动激励明显改善。
在一些实施方式中，第一壳体11设置有第一安装部111，第一扬声器单体21设置于第一安装部111内，第二壳体12设置有第二安装部121，第二扬声器单体22设置于第二安装部121内。例如，第一安装部111和第二安装部121分别设置有安装台阶面，第一振膜211可以通过点胶的方式固定于第一安装部111的安装台阶面上，第二振膜221也可以通过点胶的方式固定于第二安装部121的安装台阶面上，如此实现了第一扬声器单体21和第二扬声器单体22的安装固定。
在一些实施方式中，第一安装部111具有第一开口111a，第一振膜211与第一开口111a相对，如此可使第一振膜211通过第一开口111a发生声音，例如第一振膜211发出的声音方向与其震动方向F1同向。
在一些实施方式中，第二安装部121具有第二开口121a，第二振膜221与第二开口121a相对，如此可使第二振膜221通过第二开口121a发生声音，例如第二振膜221发出的声音方向与其震动方向F2同向。由于第二壳体12的设置方式，使得第二振膜221发出的声音方向可以改变，其声音传输的路径可以参见图3中的虚线部分。
在一些实施方式中，第一壳体11还设置有第二出声部112，第二壳体12还设置有第一出声部122，第二开口121a、第一出声部122和第二出声部112依次连通，如此可使得第二扬声器单体22发出的声音能够通过第二出声部112发出，从而增大了扬声器模组100的出声面积，进而提高了声音的响度。所以说，本实施例提供的扬声器模组100不仅能够达到两个扬声器单体(即第一扬声器单体21和第二扬声器单体22)的声音的响度，还能保证对具有该扬声器模组100的便携式电子设备的震动激励较小甚至无震动激励。
在一些实施方式中，第二出声部112的横截面积不小于第一出声部122的横截面积，如此可使得第二扬声器单体22发出的声音更容易顺畅地发出。例如，如图3、图5和图6所示，第二出声部112的横截面积大于第一出声 部122的横截面积；如图4所示，第二出声部112的横截面积等于第一出声部122的横截面积。
需要指出的是，当第二出声部112的横截面积大于第一出声部122的横截面积时，第二出声部112具有由第一壳体11的表面向内凹陷形成的台阶112a，从而使得第二出声部112的横截面积增大。
在一些实施方式中，第一安装部111和第二出声部112设置于第一壳体11的同一侧，如此可以保证由第二扬声器单体22发出的声音和第一扬声器单体21发出的声音同向，从而更方便地提高扬声器模组100的声音响度。
可以理解的是，第一安装部111和第二出声部112还可以设置于第一壳体11的不同侧，例如第一扬声器单体21发出的可以是由第一电信号激励产生的声音，第二扬声器单体22发出的可以是由第二电信号激励产生的声音，由此扬声器模组100可以发出不同的声音，但仍能保证对具有该扬声器模组100的便携式电子设备的震动激励较小甚至无震动激励。其中，第一电信号和第二电信号可以是由不同电路板驱动，也可以是由相同电路板不同的驱动模块驱动。
在一些实施方式中，第一壳体11和第二壳体12为分体成型结构。组装时，可以分别将第一扬声器单体21和第二扬声器单体22固定到第一壳体11和第二壳体12上，以分别形成第一扬声器模组10和第二扬声器模组20；再将第一壳体11和第二壳体12扣合形成扬声器模组100。在本实施方式中，第一扬声器单体21与第一壳体11形成第一后腔21a，第二扬声器单体22与所述第二壳体12形成第二后腔22a，第一后腔21a和第二后腔22a连通，即共后腔，如此可使形成的扬声器模组100结构更加紧凑。
在一些实施方式中，第一扬声器单体21与第二扬声器单体22的结构相同，如此可方便电路板对第一扬声器单体21与第二扬声器单体22的驱动控制。当然，第一扬声器单体21与第二扬声器单体22的结构也可以不相同，例如其中一个可以是动圈式扬声器，另一个可以是动圈式扬声器、电容式扬声器、压电式扬声器或其它类型的扬声器。
可以理解的是，第一扬声器单体21和第二扬声器单体22的结构可以相同也可以不同，只要保证第一扬声器单体21和第二扬声器单体22的振膜震动的方向相反即可。
在本实施方式中，第一扬声器单体21可以是具有第一振膜211的动圈式扬声器，第二扬声器单体22也可以是具有第二振膜221的动圈式扬声器，且二者的结构和大小均相同，以方便电路板的驱动控制。第一扬声器单体21与第二扬声器单体22分别包括驱动第一振膜211和第二振膜221震动的音圈，在工作状态下，振膜震动发声并推动气体压缩产生声波。
当第一扬声器单体21与第二扬声器单体22均为动圈式扬声器时，在一些实施方式中，第一扬声器单体21和第二扬声器单体22沿水平方向X错位设置，如此可大大降低二者之间的斥力(这是因为动圈式扬声器中包括磁铁，正对时二者之间的斥力最大)，从而方便扬声器模组100的组装。
下面以第一扬声器单体21为例，对其具体的结构进行说明。
如图8所示，第一扬声器单体21包括震动组件和磁路组件，震动组件和磁路组件通过支架213固定连接，磁路组件用于形成永磁场。震动组件包括第一振膜211和音圈212。第一振膜211可以为折环振膜或者平面振膜，在本实施方式中，第一振膜211以折环振膜为例进行说明。
第一振膜211悬置在磁路组件的上方，例如第一振膜211的边缘直接或者间接地固定在磁路系统的上方。音圈212的两个线端首尾连接，以形成闭合回路。通过形成闭合回路，在受到激励线圈(图中未示出，其中电路板与激励线圈电连接)激励时，音圈212能够形成感应电流。
音圈212的一端与第一振膜211连接，音圈212的另一端插入由磁路系统形成的永磁场中。根据法拉第电磁感应定律，闭合的音圈212产生感应电流，通电的音圈212在永磁场中受到安培力的作用而发生震动。音圈212震动带动第一振膜211震动，以发出声音。
磁路系统包括导磁轭214以及设置于导磁轭214上的中心磁体和边磁铁216，边磁铁216围绕中心磁铁215设置。在中心磁铁215和边磁铁216之间形成永磁场，边磁铁216为环形磁铁。
例如，导磁轭214可以为截面是矩形的片状结构，中心磁铁215也可以为截面是矩形的片状结构，边磁铁216可以为截面是矩形的环状结构。中心磁铁215和边磁铁216为轴向充磁，中心磁铁215和边磁铁216被固定在导磁轭214上。
导磁轭214起到导磁作用，导磁轭214使磁路组件形成闭合磁路，并且能聚拢中心磁铁215和边磁铁216的磁感线，提高永磁场的磁感强度。永磁场形成在中心磁铁215和边磁铁216之间的磁间隙219中，通过中心磁铁215和边磁铁216的设置，永磁场的磁感强度更高，使得扬声器单体的震动灵敏度更高。
此外，环形磁铁具有更大的面积，使得BL(B：永磁场的磁感强度；L：音圈212的有效长度)的值更大，感应电流更大，从而使得扬声器单体的震动灵敏度更高。当然，边磁铁216也可以由多个条形磁铁或者弧形磁铁围合形成，这种结构同样能与中心磁铁215一起形成永磁场。
第一扬声器单体21还包括中心导磁板217和边导磁板218，中心导磁板217设置于中心磁铁215的上方，边导磁板218设置于边磁铁216的上方。永磁场形成于中心导磁板217与边导磁板218之间，边导磁板218为环形结构。中心导磁板217和边导磁板218能起到聚拢磁感线的作用，从而使永磁场的磁感强度更高。通过这种方式，能够提高扬声器单体的震动灵敏度。
实施例二
如图4所示，其为本申请实施例二提供的扬声器模组100的剖面示意图。实施例二提供的扬声器模组100与实施例一不同点在于：第一扬声器模组10可以设置于第二扬声器模组20的正上方，第二出声部112的横截面积等于第一出声部122的横截面积。上述不同点在描述实施例一的方案中已经陈述清楚，在此不再进行赘述。
实施例三
如图5所示，其为本申请实施例三提供的扬声器模组100的剖面示意图。实施例三提供的扬声器模组100与实施例一不同点在于：第一后腔21a和第二后腔22a不连通。也就是说，实施例一提供的扬声器模组100实则为一个扬声器，而实施例三提供的扬声器模组100实则为两个扬声器。
可以理解的是，扬声器模组100具有一个扬声器还是两个扬声器，是由壳体是否独立设置而决定的。例如，实施例一提供的扬声器模组100中，第一壳体11和第二壳体12固定后形成一个整体，即为一个扬声器；实施例三 提供的扬声器模组100中，第一壳体11和第二壳体12本身各自为一个整体，只不过通过固定将两个扬声器集成在一起。
实施例四
如图6所示，其为本申请实施例四提供的扬声器模组100的剖面示意图。实施例四提供的扬声器模组100与实施例一不同点在于：第一壳体11和第二壳体12为一体成型结构。例如，第一壳体11和第二壳体12可以是一体注塑成型，如此可减少组装扬声器模组100的安装工序，即不用再将第一壳体11和第二壳体12进行固定。
综上所述，本申请提供的扬声器模组100通过将第一扬声器单体21和第二扬声器单体22沿竖直方向Y依次设置，且使第一振膜211震动的方向和第二振膜221震动的方向相反，实现了扬声器模组100的动量变化Δ(mv)相互抵消，从而可以保证对具有该扬声器模组100的便携式电子设备的震动激励较小甚至无震动激励。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
