与相关技术相比，本实用新型的移动终端将所述激励器的所述螺旋弹簧由其基座向电路板方向延伸，且所述螺旋弹簧抵接于所述电路板时呈压缩状态并使得所述基座抵接于所述屏幕模组，即所述电路板限位压缩所述螺旋弹簧以提供一定的预压力，将所述激励器抵接至所述屏幕模组以形成卡设固定，同时在所述螺旋弹簧由导电材料制成，实现将所述激励器的所述线圈与所述电路板电连接以获取电信号，因所述螺旋弹簧由基座底部沿垂直于所述电路板方向延伸，使得所述线圈的压缩方向为垂直于所述屏幕模组，节省了所述移动终端沿其长度方向的空间尺寸；而所述螺旋弹簧因受到所述电路板的预压力处理压缩状态，具有一定幅动的范围，固定效果好，提高了跌落时的可靠性，且装配简单，确保了所述移动终端的发声效果一致性好。
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。
