请同时参阅图1-4所示，本实用新型提供了一种移动终端100，其包括框架1以及扬声器箱2。
所述框架1凹陷形成收容部10，该收容部10为所述扬声器箱2提供了安装空间，所述收容部10包括底面101以及连接于所述底面101并环绕所述底面101的侧面102。
所述扬声器箱2收容于所述收容部10内并与所述框架1固定。
在本实施方式中，所述扬声器箱2包括具有出声孔2110的壳体21和收容固定于所述壳体21内的发声单体22。

所述壳体21包括主体部211以及由所述主体部211向外弯折延伸的弹性固定臂212，所述弹性固定臂212的末端与所述主体部211间隔；当将所述扬声器箱2装设于终端的安装空间时，所述弹性固定臂212用于弹性压缩卡设于该安装空间内以使所述扬声器箱2与该终端形成固定。
进一步的，所述主体部211包括相对间隔设置的底壁2111和顶壁2112以及连接所述底壁2111和所述顶壁2112的侧壁2113，所述侧壁2113平行于所述振膜221的振动方向，所述弹性固定臂212由所述侧壁2113向远离所述底壁2111的方向弯折延伸形成，所述振膜221固定于所述底壁2111，所述出声孔2110沿所述振膜221的振动方向贯穿所述底壁2111设置，所述振膜221朝向所述出声孔2110设置，以形成正面发声结构。
而在本实施方式中，将所述扬声器箱2装配到所述移动终端100时，只需将所述扬声器箱2直接插入所述收容部10内即可，使得装配更加方便，有效地提高装配效率，此时，所述扬声器箱2固定收容于所述收容部10内，并通过所述弹性固定臂212压缩抵接于所述侧面102以使所述扬声器箱2与所述框架1形成固定，在弹力的作用下，使得所述扬声器箱2始终与所述框架1固定，保证所述扬声器箱2不易从所述框架1中掉落，从而提高所述扬声器箱2的安装固定的可靠性。
需要说明的是，所述移动终端100的框架1设有贯穿所述底面101并与外界连通的导声通道1010，所述出声孔2110与所述导声通道1010连通，从而实现发声，因此，为了避免外界的水或水汽通过所述壳体21和所述框架1之间的间隙进入到所述移动终端100的内部，在本实施方式中，将所述主体部211抵接固定于所述底面101以形成所述主体部211和所述底面101之间的密封，所述弹性固定臂212压缩夹紧于所述主体部211与所述侧面102之间以使所述主体部211与所述底面101之间保持压紧状态。
将所述扬声器箱2装配于所述移动终端100时，所述底壁2111朝向所述底面101装配，此时所述底壁2111抵接固定于所述底面101以形成所述底壁2111与所述底面101之间的密封，所述弹性固定臂212由所述侧壁2113向远离所述底面101的方向弯折延伸形成，所述弹性固定臂212压缩夹紧于所述侧壁2113与所述侧面102之间。

值得一提的是，所述弹性固定臂212设置在相对间隔的两个所述侧壁2113上，其具体的数量是不限，其可以根据实际使用的需要进行具体的设置。
进一步的，比如，在本实施方式中，所述弹性固定臂212包括四个，以所述壳体21呈矩形为例展开说明，四个所述弹性固定臂212环绕所述壳体21设置，所述侧壁2113包括位于所述壳体21长轴的相对两侧的两个长侧壁以及位于所述壳体21短轴的相对两侧的两个短侧壁，其中，两个所述弹性固定臂212分别设置在的两个所述长侧壁上，另外两个所述弹性固定臂212分别设置在两个所述短侧壁上，通过上述设置，使得所述壳体21四周的受力更加均匀，提高所述壳体21与所述侧面102之间固定的可靠性。
更优的，所述第一段2121和所述第二段2122的连接处设置呈倒圆角结构2123，在装配过程中，所述侧面102先与所述第一段2121抵接，然后所述侧面102再通过两者之间的连接处过渡到与所述第二段2122抵接，由于该倒圆角结构2123具有一定弧度，使得所述侧面102能够平稳地过渡到与所述第二段2122抵接，同时使得所述倒圆角结构2123与所述侧面102之间不产生刚性碰撞或摩擦，从而有效地保护了所述侧面102，有效地提高了装配可靠性；另外，由于该倒圆角结构2123，使得所述弹性固定臂212被压缩夹紧时，该倒圆角结构2123有效地使得所述第一段2121和所述第二段2122的连接处所受到的应力均匀地分布，避免了由于应力过于集中而损坏所述弹性固定臂212，提高了所述扬声器箱2与所述框架1之间的固定可靠性。
与相关技术相比，本实用新型的扬声器箱，其包括具有出声孔的壳体和收容固定于所述壳体内的发声单体，所述发声单体包括用于振动发声的振膜，所述振膜与所述出声孔连通；所述壳体包括主体部和由所述主体部向外弯折延伸的弹性固定臂，所述弹性固定臂的末端与所述主体部间隔，上述结构中，当将所述扬声器箱装设于终端的安装空间时，所述弹性固定臂用于弹性压缩卡设于该安装空间内以使所述扬声器箱与该终端形成固定，在弹力的作用下，使得扬声器箱始终与终端固定，保证扬声器箱不易从终端中掉落，从而提高扬声器箱的安装固定的可靠性。
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。
