请参阅图7及图8，所述电路板5呈“T”型结构，其包括两端分别与两个所述焊盘433连接的第一部分51、与所述第一部分51相对设置的第二部分52及连接所述第一部分51和所述第二部分52的第三部分53。所述第一部分51对应收容于所述第二凹槽3132，所述第三部分53对应收容于所述第一凹槽3131，所述第二部分52自所述第三部分53延伸至所述扬声器100外侧用于与外界电路电连接。
优选的，所述第一部分51与所述焊盘433通过热压熔锡焊接固定连接，连接牢靠，同时可以减少软板连接器的数量，节约成本。
与相关技术相比，本实用新型提供的扬声器100，通过在磁轭31的下表面3111开设凹槽313，并将电路板5收容于所述凹槽313内，所述电路板5用于所述电连接件4和外界电路的电连接，实现了空间的合理利用，保证了所述扬声器100较小的成品高度，满足微小化的需求。
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。
