具体的，本申请公开了一种升降扬声器机构，如图1至图4所示，所述升降扬声器机构包括安装支架1、外壳2、扬声器3和驱动组件4，所述 安装支架1容设在所述外壳2内，所述安装支架1一端用于支撑所述扬声器3，所述安装支架1的另一端与所述驱动组件4连接，所述驱动组件4驱动所述安装支架1在所述外壳2内上下运动；
所述安装支架1上设置有至少两个第一导向单元11，所述外壳2上对应设置有至少两个第二导向单元21，所述第一导向单元11沿所述安装支架1的周向布置，所述第二导向单元21沿所述外壳2的周向布置，所述第一导向单元11被设置为，当所述驱动组件4驱动所述安装支架1在所述外壳2内上下运动时，所述第一导向单元11相对于所述第二导向单元21上下运动。通过在安装支架1和外壳2上分别设置相互配合的导向单元，实现扬声器3升降过程中的导向，减弱扬声器3升降过程中的抖动现象，降低噪音，并且，直接在安装支架1和外壳2上形成导向单元，不需要额外配置导向件，使得扬声器3机构的整体结构更加紧凑，空间占用更少。
