所述第二振膜22包括第二球顶221及环绕所述第二球顶211设置的第二折环222。
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，此时，第一音圈31与第一电路板51胶合时多余的胶水会渗入所述收容槽5113中，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，且定位镶件穿过第一电路板上51上的断口部5114支撑所述第一音圈31，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系统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，所述第一电路板包括与所述第一音圈固定的内固定端、与所述盆架固定的外固定端以及连接所述内固定端与所述外固定端的连接臂，所述内固定端包括与所述第一音圈抵接的第一表面，所述第一表面自其内侧凹陷形成收容槽，以在所述第一音圈与所述第一电路板胶合时收容多余的胶，所述收容槽上设有断口部以便组装所述扬声器时避让所述第一音圈的定位镶件。本实用新型的第一电路板的内固定端局部减薄形成收容槽，可以在第一音圈与第一电路板的第一表面胶合时存胶，可防止胶水下渗至第一电路板的第二表面，从而保证了第二表面与第一振膜结合的平整度，避免了胶水污染；同时，收容槽上的断口部让位第一音圈的定位镶件，保证了第一电路板、第一音圈与第一振膜胶合可靠性。
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。
