【具体实施方式】
下面结合附图和实施方式对本发明作进一步说明。
如图1至图4所示，依照本发明一实施例提供一种应用于便携式电子设备100的扬声器箱200，便携式电子设备100包括壳体50，壳体50内形成有用于容置扬声器箱200的腔体1，具体地，壳体50包括第一壳体51和第二壳体52，第一壳体51设有用于安装扬声器箱200的安装槽511，第二壳体52盖合在第一壳体51上，从而形成用于容置扬声器箱200的腔体 1。
请参阅图5至图8，扬声器箱200包括具有收容空间2的箱体10和收容于箱体10内的具有出声口的扬声器单体20，具体地，箱体10包括第一盖体11和第二盖体12，第一盖体11和第二盖体12组合形成有用于收容扬声器单体20的收容空间2，扬声器单体20将收容空间2分隔为与出声口连通的前腔3和与前腔3相对的后腔4(见图6)，第一盖体11上设有连通前腔3的第一出声孔111，第一壳体51靠近扬声器第一出声孔111(见图5)的位置对应设有第二出声孔512。箱体10设有用于连通后腔4和便携式电子设备100腔体1的通孔30，该通孔30设置有若干个，各个通孔30具有不同的朝向，在各个通孔30处均设置有透气隔离件40，用于实现扬声器箱200后腔4和便携式电子设备100腔体1的连通，从而扩大扬声器箱200后腔4。
优选地，透气隔离件40为无纺布或无尘网布，粘贴在通孔30处；或者透气隔离件40为金属网，焊接在通孔30处。
参考图5至图8所示，优选地，通孔30设于第一盖体11上，在本实施例中，设有两个通孔30，第一通孔31设于第一盖体11的前表面，朝向与第一出声孔111的朝向一致，第二通孔32设于第一盖体11的底面，朝向与第一通孔30相互垂直。
参考图1至图3所示，本发明还提供一种便携式电子设备100，包括壳体50和如上所述的扬声器箱200。优选地，便携式电子设备100包括四个角，扬声器箱200可以安装在便携式电子设备100的一个角上，或者多个角上，或者每一个角均安装有扬声器箱200，以达到更好的声学效果。
优选地，便携式电子设备100为手机或平板电脑或者其他需要应用到扬声器箱200的便携式电子设备100。
随着市场上的便携式电子设备都开始倾向于防水设计，便携式电子设备整体的密封效果进一步提升，在此前提下，可以对扬声器箱做出具有创造性的改进，在不带入灰尘等杂质从而影响扬声器单体工作的情况下，连通扬声器箱的后腔和便携式电子设备的腔体，充分利用便携式电子设备的 腔体空间，满足扬声器箱后腔大空间的需求。依据本发明一实施例概述如下：在扬声器箱200箱体10上设置通孔30，用于连通扬声器箱200的后腔与应用该扬声器箱200的便携式电子设备100的腔体1，并在通孔30处设置透气隔离件40，在确保外界的灰尘等杂质不能进入扬声器箱200内部进而影响扬声器单体工作的情况下，可有效增加扬声器箱200后腔4的空间，如此设置，则扬声器箱200箱体10可以制作得更小，在一定程度上减小了扬声器箱200的体积，随着扬声器箱200的体积减小，需要在便携式电子设备100上预留安装扬声器箱200的空间减小，从而能在便携式电子设备100的多个角或全部角都安装扬声器箱200，以达到更好的声学效果。
需要说明的是，本发明实施例中所有方向性指示(诸如上、下、左、右、前、后、内、外、顶部、底部……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
还需要说明的是，当元件被称为“固定于”或“设置于”另一个元件上时，该元件可以直接在另一个元件上或者可能同时存在居中元件。当一个元件被称为“连接”另一个元件，它可以是直接连接另一个元件或者可能同时存在居中元件。
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
