请参阅图1-7，本发明实施例提供的一种扬声器100，包括盆架10、安装在盆架10上的振动系统20和安装在盆架10上以用于驱动振动系统20振动发声的磁路系统30。
盆架10包括用于收容磁路系统30的底框11和固定于磁路系统30上的顶盖12，底框11包括底板111和凸设于底板111边缘的第一侧板112，顶盖12包括顶板121、凸设于顶板边缘的第二侧板122和凸设于顶板121中间的凸块123，凸块123之远离顶板121的一侧与磁路系统30连接。优选地，底板111和顶板121平行设置，第一侧板112从底板111的边缘朝向顶板121所在侧延伸，第二侧板122从顶板121的边缘朝向底板111所在侧延伸。
振动系统20包括第一环形振膜21、第二环形振膜22、环形球顶23、音圈24、环形骨架25以及连接骨架26，第一环形振膜21的外侧与底框11连接，具体与第一侧板112连接，第一环形振膜21的内侧与环形骨架25的环形底部连接，环形骨架25的环形顶部与环形球顶23的外侧连接，第二环形振膜22的外侧与环形球顶23的内侧连接，第二环形振膜22的外侧与顶盖12连接，具体与第二侧板122连接，连接骨架26的一端与音圈24连接、另一端与环形球顶23连接。通过设置振动系统20包括第一环形振膜21和第二环形振膜22的双振膜结构，可以使得振动系统20的振动更为平衡，有效减少因振动不平衡产生的杂音，有效提升音质；此外，通过上述的连接方式，第一环形振膜21、第二环形振膜22、环形球顶23、环形骨架25、底框11以及顶盖12整体可以围合形成一个密封的空间，保证密封性。

磁路系统30位于第二环形振膜122的内侧。通过将磁路系统30设置成位于第二环形振膜122的内侧，振动系统20在音圈24的振动方向上不会对音圈24造成阻碍，可以大幅提高音圈24的有效振动空间，提升扬声器100的功率，且便于磁路系统30的优化设计。
磁路系统30包括安装于底框111中间的导磁板31、设置于导磁板31中间的主磁钢32、四个设置于导磁板31上并环绕主磁钢32设置的副磁钢33、贴附于主磁钢32之远离导磁板31一侧的主极芯34和四个分别贴附于四个副磁钢33之远离导磁板31一侧的副极芯35，主磁钢32和副磁钢33间隔设置，音圈24可活动套设于主磁钢32外。可以理解地，副磁钢33不局限于设有四个，例如副磁钢33设有两个，两个副磁钢33分别设置于主磁钢32的两相对侧也是可以的。
底板111的中间开设有通孔113，导磁板31嵌设于通孔113中。由于扬声器100尺寸的限制，底板111到环形球顶23的距离有限，通过在底板111上开设通孔113，将导磁板31嵌设于通孔113中，可以减小导磁板31占用底板111到环形球顶23的距离，从而可以增大音圈24的有效振动空间，提高了扬声器100的功率。
以上所述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。
