所述第二电路板52与所述第二音圈32电性连接。
组装所述扬声器100时，所述盆架1与所述磁碗41、第二极芯45注塑固定，磁碗41的延伸部413注塑固定于盆架1的短轴方向上，第二极芯45注塑固定于盆架1的长轴方向上，将所述第一磁钢42、第一极芯43固定于所述磁碗41的平板部411，同时，所述第一音圈31与所述第一电路板51胶合固定，将盆架1翻转到音圈的定位镶件上，此处使用的是同一定位工装，通过第一电路板51的外固定端514与盆架1贴合固定，从而将第一音圈31与盆架1固定，使得第一音圈31与盆架1的同心度得到了保证，最后将第一振膜21与第一电路板51固定从而完成部分扬声器的组装。需要注意的是，在第一振膜21与第一电路板51的固定过程中，工装会通过磁碗41上的第一缺口414对第一电路板51与第一振膜21、通过第二缺口415对第一音圈31与第一振膜21进行压合，从而保证了第一音圈31、第一振膜21、第一电路板51三者之间的胶合固定。然后再从盆架1的另一面对第二电路板52、第二磁钢44、框架6、第三极芯46、第二音圈32、第二振膜22进行组装，最终完成对扬声器100的组装。
与相关技术相比，本实用新型的扬声器，其包括盆架、支撑于所述盆架的第一振膜、驱动所述第一振膜振动发声的第一音圈、具有第一磁间隙的磁路***以及设置于所述第一振膜与所述第一音圈之间的第一电路板，所述磁路***包括磁碗以及固定于所述磁碗的第一磁钢，所述第一电路板包括与所述第一音圈固定的内固定端、自所述内固定端延伸出来的焊盘、自所述焊盘延伸出来的连接臂以及与所述连接臂连接且固定于所述盆架的外固定端，所述磁碗包括承载所述第一磁钢的平板部及自所述平板部的两侧弯折延伸的弯折部，所述弯折部与所述第一磁钢之间形成所述第一磁间隙，所述磁碗的弯折部于所述焊盘处设有第一缺口，所述焊盘暴露于所述第一缺口以便组装所述扬声器时工装便于定位所述第一电路板与所述第一振膜。本实用新型的磁碗正面位置设置了缺口作为避让，装配顺序可调整为：磁碗通过注塑与盆架结合，第一磁钢与磁碗组装，第一音圈与第一电路板组装后，将盆架翻转到第一音圈的定位镶件上，此时使用的是同一定位工装，保证盆架与第一音圈的同心度，最后将第一振膜胶合件与盆架、第一音圈胶合件组装，通过缺口的位置压合，保证第一电路板与振膜胶合可靠性，此种方案下磁间隙可以进一步做小，提升SPL。
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。
