 本发明的实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本实用新型的一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，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它实施例，都属于本实用新型保护的范围。
请同时参阅图1-5，本实用新型提供了一种移动终端100，包括外壳1、屏幕2、扬声器箱3、出声部4以及驱动电机5。所述屏幕2盖设于所述外壳1并与所述外壳1共同围成收容空间10。
具体的，所述外壳1包括底壁11、由所述底壁11周缘弯折延伸的侧壁12、贯穿所述侧壁12设置的开口13以及由所述底壁11延伸并形成于所述收容空间10内的出声滑道14。
所述屏幕2盖设支撑于所述侧壁12，图2中仅示屏幕2的部分结构。
所述扬声器箱3安装于所述收容空间10内。所述扬声器箱3设有侧面出声的出声口31，所述出声口31朝向所述侧壁12开设。
所述出声部4包括呈中空状的壳体41和贯穿所述壳体41的声口42。所述壳体41固定于所述扬声器箱3的侧面且使得所述扬声器箱3的所述出声口31与所述壳体41的内部连通，所述声口42朝向所述屏幕2开设，从而形成屏幕侧发声结构。
具体的，所述壳体41包括靠近所述屏幕2的上表壁411、与所述上表壁411相对设置的下表壁412以及连接所述上表壁411与所述下表壁412的侧表壁413，所述声口42开设于所述上表壁411，所述扬声器箱3与所述侧表壁413固定连接。

与相关技术相比，本实用新型的移动终端中通过设置与所述扬声器箱的出声口连通的出声部，并在出声部开设朝向屏幕的声口，通过驱动电机驱动扬声器箱直线运动以带动所述出声部伸出至所述收容空间外或缩回至所述收容空间内，从而实现了全屏结构的同时实现屏幕侧发声结构，不再受整机窄缝尺寸的限制，提升了立体声效果的同时避免了窄缝出声的立体声钢琴音杂音问题，整体性能更优。
以上所述的仅是本实用新型的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出改进，但这些均属于本实用新型的保护范围。
