 本发明的实施方式
下面结合附图和实施方式对本实用新型作进一步说明。
实施例：
请参阅图1和图2，是本实用新型提供的一种扬声器箱100及终端设备，终端设备具有支撑并固定扬声器箱100的支撑件200。请一同参阅图3和图6，扬声器箱100包括具有容置空间4的壳体1以及收容于容置空间4内的发声单体3，壳体1与发声单体3之间形成有前声腔6，壳体1开设有与前声腔6连通的出声孔1121。
壳体1包括固定于支撑件200的底壳11、以及盖设于底壳11并与底壳11围成容置空间4的金属顶板12，底壳11包括与金属顶板12相对且间隔设置的底壁111以及自底壁111周缘朝金属顶板12弯折延伸的侧壁112，金属顶板12包括盖设于侧壁112远离底壁111一端的主体部121以及自主体部121向外延伸的定位臂122，定位臂122远离侧壁112的一端对应嵌设于支撑件200。
本实用新型的扬声器箱100装配在终端设备时，扬声器箱100的定位臂122可以与终端设备上的支撑件200嵌设固定，从而使得扬声器箱100与终端设备的支撑件200之间实现稳定可靠的定位和紧固，降低了扬声器箱100在终端设备整机中应用的局限性。
具体地，支撑件200上设有与定位臂122固定的定位块5，定位块5上设有与定位臂122匹配的定位槽孔51，定位臂122嵌设于定位块5并与定位槽孔51插接固定。
本实施例中，如图4和图5所示，定位臂122包括自主体部121朝底壁111方向弯折延伸的弯折部1221以及自弯折部1221的远离主体部121的一端朝远离侧壁112方向延伸的延伸部1222。而为了方便定位臂122与定位槽孔51插接固定，并且不易脱落，弯折部1221的延伸方向和延伸部1222的延伸方向形成一个钝角，相应地，定位槽孔51也应设置为与弯折部1221和延伸部1222适配的分段结构。可以理解的是，在其他可能的实施方式中，弯折部1221的延伸方向和延伸部1222的延伸方向可以形成一个180°角，即定位臂122不具有弯折结构，同样可以与终端设备的定位槽孔51插接固定。具体地，延伸部1222的延伸方向与侧壁112垂直，更加便于定位臂122与定位槽孔51插接。
另外，为了使得定位臂122插入定位槽孔51时更为顺畅，没有卡顿感，弯折部1221和延伸部1222之间采用圆弧过渡，并且弯折部1221和延伸部1222的长度相等，这样设置也可以避免尖锐结构损坏终端设备。当然，在其他可能的实施方式中，弯折部1221和延伸部1222之间也可以采用斜面过渡。
如图3和图4所示，出声孔1121开设于侧壁112，主体部121呈矩形，定位臂122至少形成于主体部121的相邻两侧。本实施例中，定位臂122的数量为两个且主体部121的相邻两侧各设有一个定位臂122，相应地，定位块5的数量也为两个，位于两个不同方向的定位臂122的设置可以使得扬声器箱100与支撑件200的连接更加稳固。在其他可能的实施方式中，定位臂122的数量可以为三个、四个或五个等，可以在主体部121的各个侧面都设置一个定位臂122，还可以在主体部121一侧设置多个定位臂122，本实施例对定位臂122的数量和设置方位不做限制，可根据具体情况调整。为了避免对扬声器箱100的出声造成影响，定位臂122均位于主体部121远离出声孔1121的一侧。
本实施例中，发声单体3与金属顶板12间隔形成前声腔6，底壳11为金属底壳11，底壳11和金属顶板12的连接方式可以为焊接，也可以通过螺丝等紧固件固定连接。扬声器箱100还包括安装于壳体1内的导声支架2，导声支架2自金属顶板12延伸至出声孔1121并形成有连通前声腔6与出声孔1121的导声通道21。
综上所述，本实用新型的扬声器箱100装配在终端设备时，扬声器箱100的定位臂122可以与终端设备上的支撑件200嵌设固定，从而使得扬声器箱100与终端设备的支撑件200之间实现稳定可靠的定位和紧固，降低了扬声器箱100在终端设备整机中应用的局限性。
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。
