如图8所示，在一种可能的实施例中，盆架2包括多个沿第二主体部22周向间隔设置的连接件23，连接件23的一端与第一主体部21连接，另一端与第二主体部22连接。
连接件23能够连接第一主体部21和第二主体部22，多个连接件23沿第二主体部22的周向间隔设置能够提高第一主体部21和第二主体部22之间的连接强度，进而提高盆架2的使用寿命。
如图3所示，在一种可能的实施例中，沿移动件45的周向设置多个通过孔451，通过孔451与连接件23对应设置，使连接件23的至少部分能够穿过通过孔451。

如图6和图7所示，在一种可能的实施例中，第二音圈42包括相互连接的第一本体部421和第二本体部422，第一本体部421位于第一导磁件112对应的磁间隙内，第二本体部422沿第三导磁件114的周向设置于第三导磁件114的外表面与移动件45连接。
导磁组件11和磁体组件12形成图7中箭头所示的磁路，在第二线圈421a内通入电流能够使位于第一导磁件112对应的磁间隙内的第一本体部421沿扬声器的高度方向Z运动，第二本体部422与第一本体部421连接，使第一本体部421能够带动第二本体部422运动，第二本体部422设置于第三导磁件114的外表面便于与移动件45连接，进而带动移动件45和第二振膜41运动，以使第二发声单元4发声。
如图6和图7所示，在一种可能的实施例中，第二本体部422设置有沿靠近第一本体部421的方向延伸的凸起部422a，凸起部422a的至少部分能够穿过限位槽114a，且能够沿限位槽114a的延伸方向Z运动，第一本体部421和第二本体部422通过凸起部422a连接。
凸起部422a的至少部分能够穿过限位槽114a，且能够沿限位槽114a的延伸方向运动，使第一本体部421能够带动第二本体部422运动。

由于第一本体部421与第二本体部422连接，柔性基板46与第二本体部422连接，能够通过第二本体部422将电流通入第一本体部421，使第一本体部421在磁路的作用下沿扬声器的高度方向Z运动。
第一本体部421包括相互连接的第二线圈421a和第二线圈支架421b，第二线圈421a与第二本体部422连接，使柔性基板46通过第二本体部422将电流通入第二线圈421a，第二线圈支架421b位于第二线圈421a靠近第二导磁件113的一侧。
