请参阅图1、图2和图3，进一步地，发声单体2还包括设置于盆架21远离磁路系统23一侧的上盖24、以及两端分别固定连接于盆架21和球顶骨架222的柔性电路板224，上盖24与盆架21相适配，第二折环设于盆架21和上盖24之间，及振膜221通过盆架21和上盖24夹持固定；柔性电路板224设于盆架21远离上盖24的一侧，柔性电路板224设有两个且分布在磁路系统23的两侧，有利于振动系统22对称设置，从而提升振动系统22的振动效果。应当理解，音圈223与线圈4所在电路相互独立设置，使音圈223与线圈4可以分开工作也可以同时工作，便于满足不同的应用场景对线圈4和音圈223工作与否的需求。
以上的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
