图3是图1中的扬声器箱的结构示意图；
图4是图2中的壳体和第一凸台的结构示意图；
图5是图2中的定位块的结构示意图；
图6是本实用新型另一种实施方式提供的扬声器箱的结构示意图；
图7是本实用新型另一种实施方式提供的定位块的结构示意图。
 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终端设备，包括框架200以及固定于框架200的扬声器箱100，请一同参阅图4，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，框架200包括与扬声器箱100固定的连接面51，壳体1为金属壳体1，壳体1的侧壁与连接面51相互扣合固定。
本实用新型的终端设备在装配扬声器箱100时，壳体1的侧壁可以与终端设备框架200上的连接面51相互扣合固定，从而使得扬声器箱100与终端设备框架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。
于本实用新型的其中一种可能的实施方式中，如图3至图5所示，壳体1的侧壁设有第一凸台60，连接面51上开设有与第一凸台60适配的第一凹槽70，第一凸台60和第一凹槽70相互扣合。具体地，第一凸台60包括与连接面51正对的顶面61以及连接顶面61和壳体1的侧壁的第一导向面62，第一凹槽70包括与第一凸台60正对的底面71以及连接底面71和连接面51的第二导向面72，在第一凸台60和第一凹槽70扣合时，第一导向面62先与第二导向面72相互抵顶配合，从而能够起导向作用，实现顺畅的扣合连接。
可选的，第一导向面62可以是斜面或者弧面，第二导向面72则是与第一导向面62相适配的斜面或弧面，当然，第一导向面62和第二导向面72也可为除斜面和弧面以外的其他结构，只要能够保证实现顺畅的扣合连接即可，本实施例对第一导向面62和第二导向面72的具体结构不做限制。
于本实用新型的另一种可能的实施方式中，如图6和图7所示，连接面51上设有第二凸台90，壳体1的侧壁上开设有与第二凸台90适配的第二凹槽80，第二凸台90和第二凹槽80相互扣合。第二凸台90和第二凹槽80的表面均为圆弧面，这样设置可以避免尖锐结构损坏第二凸台90或第二凹槽80。
本实施例中，框架200对应壳体1侧面的位置设置有至少一个定位块5，连接面51设置在定位块5上。具体地，壳体1的相邻两个侧面分别设置有定位块5，从而能够在两个不同方向实现壳体1和定位块5的扣合连接，使得扬声器箱100与终端设备的连接更加稳固。在其他可能的实施方式中，可以在壳体1的各个侧面都设置一个定位块5，还可以在壳体1的一个侧面上设置多个第一凸台60或第二凹槽80，具体可根据实际情况调整。
进一步地，如图2和图4所示，壳体1包括底板11以及盖合于底板11上的顶壳12，底板11和顶壳12合围形成容置空间4，顶壳12的侧壁开设有将容置空间4与外界连通的通孔121。底板11和顶壳12均由金属材料制成，底板11和顶壳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。
另外，本实施例的扬声器箱100还包括部分收容于容置空间4内且外露于通孔121的机壳2，机壳2对应于通孔121的位置开设有出声孔21。
综上所述，本实用新型的终端设备在装配扬声器箱100时，壳体1的侧壁可以与终端设备框架200上的连接面51相互扣合固定，从而使得扬声器箱100与终端设备框架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。
