具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例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他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的 电子设备进行详细地说明。
如图1所示，本申请实施例提供一种电子设备，所述电子设备包括：
屏幕11；
壳体12，所述壳体12形成有收容空间，所述收容空间内收容有声学元件13，所述屏幕11设于所述壳体12一侧，所述壳体12和/或所述屏幕11形成有出音孔14，所述声学元件13与所述出音孔14之间形成前腔15；
其中，所述收容空间内设有滤波管道16，如图2所示，所述滤波管道16与所述前腔15连通，且所述滤波管道16的长度与待滤波声波的波长呈预设比例关系。
其中，所述滤波管道16的长度可以为待滤波声波的波长的1/4，或者，所述滤波管道16的长度可以为待滤波声波的波长的1/3，或者，所述滤波管道16的长度可以为待滤波声波的波长的1/5，等等，本实施例对预设比例不进行限定。
一种实施方式中，所述滤波管道16的长度由待滤波声波的波长决定，本实施例中以滤波管道的长度是待滤波声波的波长的1/4为例。在确定了带滤波声波的波长之后，滤波管道的长度可以精确到1/4，也可以是有一点点偏差区间(即波长的1/4附近)，这对于滤波管道的滤波性能也不会有太大的影响。本实施例对此不进行限定。
另外，声学元件13可以包括扬声器或受话器等。声学元件13、出音孔14及前腔15配合，使得声学元件13发出的声波经过前腔15，从出音孔14传出电子设备。与前腔15连通的滤波管道16具有滤波的功能，并且能够降低声学元件13的总谐波失真。如图3所示，滤波管道16的长度可以为从滤波管道16的起点161到滤波管道的末端162经过的路径。作为一种具体的实施方式，所述滤波管道16的长度可以为待滤波声波的波长的1/4，当滤波管道16的长度为待滤波声波的波长的四分之一时，滤波管道16可以较好地对该待滤波声波进行滤波，降低其声波能量。
如图4所示，声波经过前腔15时，从滤波管道的起点161传输至滤波管道的末端162，反射回滤波管道的起点161，声波反向叠加，能够降低声波的噪声。如图5所示，a1为声波到达滤波管道的起点161时的波形，a2为继续 向前传播半个波长的波形，a3为经过滤波管道后反射回起点161的波形，a2和a3反相叠加，能够削弱原始噪声。示例地，若需要对4200Hz的声波进行滤波，以声波速度按340m/s计算，4200Hz对应的声波的波长约为80.95mm，可以设计滤波管道16的长度为20.23mm。采用设计有该滤波声波的电子设备以及未设计该滤波声波的电子设备进行试验，如图6所示，声波在4200Hz频率时，设计有该滤波声波的电子设备比未设计该滤波声波的电子设备的声压级降低10dB左右，其中，图6中虚线部分为设计有该滤波声波的电子设备的声压级曲线，实线部分为未设计该滤波声波的电子设备的声压级曲线。从而能够有效改善声音尖锐问题，改善听感，使得声音更柔和。如图7所示，总谐波失真在4200Hz时有小幅降低，在1000～2000Hz时的总谐波失真(Total Harmonic Distortion，THD)改善明显，其中，图7中虚线部分为设计有该滤波声波的电子设备的THD曲线，实线部分为未设计该滤波声波的电子设备的THD曲线。
需要说明的是，所述壳体12可以包括框体121，所述框体121上可以收容有声学元件13。所述滤波管道16可以成型于所述框体121上。框体121可以通过双面胶与屏幕11粘结，屏幕11与框体121之间可以形成声学元件13的前腔15。
