进一步地，振动组件200还包括柔性连接件240以及平衡件250，柔性连接件240分别连接于盆架100以及骨架220，柔性连接件240具有电连接于音圈210的焊盘部244，焊盘部244固定于骨架220上，并位于音圈210的一侧；平衡件250设于骨架220上，并位于音圈210远离焊盘部244的一侧。
在本实施例的扬声器模组10中，柔性连接件240上的焊盘部244与音圈210电连接以建立电流通路，且焊盘部244位于振动组件200的音圈210的一侧，骨架220上位于音圈210的另一侧设置有平衡件250，通过设置的平衡件250可以平衡焊盘部244的重量，以使骨架220在音圈210的相对两侧具有平衡的质量。本实施例的扬声器模组10通过在音圈210远离焊盘部244的一侧设置平衡件250，平衡件250可以平衡焊盘部244的重量，从而提高骨架220的运动稳定性。
可以理解地是，音圈210上具有伸出的第一电连接端和第二电连接端，且第一电连接端和第二电连接端分别连接于焊盘部244，柔性连接件240与外部电源连接，并通过焊盘部244对音圈210进行供电，通过振动组件200与磁路组件300的配合实现扬声器模组10的发声功能。具体在一实施例中，柔性连接件240至少包括部分柔性电路板的结构。
参阅图2所示，定义图中X方向为音圈210的移动方向，具体参阅图3和图4所示的实施例中，沿X方向，骨架220具有相对设置的第一安装面221和第二安装面222，第一安装面221上设有凹槽2211，焊盘部244至少部分设于凹槽2211内；第二安装面222连接于主振膜230。
通过在骨架220上设置的凹槽2211，在组装本扬声器模组10时，可以将焊盘部244置于该凹槽2211内，并将焊盘部244与骨架220固定连接，既可以对焊盘部244进行定位，同时也可以充分利用骨架220在X方向上的空间，以使振动组件200具有紧凑的结构。具体地，焊盘部244与骨架220可以采用例如粘接、焊接、铆接等固定连接方式进行连接。
请继续参阅图4所示，凹槽2211的数目为两个，两个凹槽2211分别设于音圈210的相对两侧，如图3所示的摆放状态，两个凹槽2211分别设于音圈210在水平方向上的相对两侧；焊盘部244与其中一种凹槽2211相配合，平衡件250至少部分设于另一个凹槽2211内。
可以理解地是，通过在骨架220上设置两个凹槽2211，在组装振动组件200的过程中，通过设置的两个凹槽2211可以分别对焊盘部244和平衡件250进行定位，同时也可以使振动组件200在X方向上具有紧凑的结构。
进一步地，两个凹槽2211对称设于音圈210的相对两侧，也就是说，两个凹槽2211与音圈210之间的间距相等，由此设置，在组装本扬声器模组10的过程中无需对骨架220进行定向，设于骨架220上的两个凹槽2211任意一个对应于焊盘部244即可，安装便捷性得以提高。
在其他实施例中，两个凹槽2211也可以设置为与音圈210之间的间距不相等，由此设置，便需要根据两个凹槽2211与音圈210之间的间距调整平衡件250的对应重量。
参阅图1和图4所示，在一实施例中，第二安装面222上形成有与凹槽2211相对应的凸部2221；主振膜230设有第一安装槽2311，凸部2221与第一安装槽2311相适配。
在本实施例中，骨架220使用例如冲压等不去除材料的方法进行加工，通过在骨架220的第一安装面221的形成凹槽2211，与第一安装面221相对的第二安装面222上即形成凸出第二安装面222的凸部2221，主振膜230上开设的第一安装槽2311与凸部2221对应，凸部2221的外表面至少部分抵接于第一安装槽2311的内壁，由此即可对主振膜230的安装进行定位。在其他实施例中，也可以使用切削等去除材料的方式加工形成凹槽2211，由此即可在第二安装面222与凹槽2211对应的部位形成平面，即取消设置的凸部2221，从而使振动组件200具有更为紧凑的结构。
具体地，在本实施例中，柔性连接件240为两个，且分别为第一柔性连接件240a和第二柔性连接件240b，焊盘部244设于第一柔性连接件240a上，参阅图6所示的摆放状态，第一柔性连接件240a设于音圈210的左侧，第二柔性连接件240b设于音圈210的右侧。
在本实施例的扬声器模组10中，焊盘部244与骨架220连接，并使骨架220处于重量不平衡的状态，此时通过在音圈210的右侧设置平衡件250，平衡件250可以对音圈210远离焊盘部244的一侧进行配重，以使骨架220的整体重量处于平衡的状态，也就是左右对称，此时音圈210驱动骨架220振动时，骨架220便具有更为稳定的振动效果，扬声器模组10的发声效果也得以提高。
进一步地，柔性连接件240具有固定部241、柔性部242以及连接部243，柔性部242分别连接于固定部241和连接部243，连接部243与骨架220固定连接，固定部241与盆架100固定连接，且连接部243可相对于固定部241移动。
参阅图6所示，在一实施例中，第一安装槽2311的数目为两个，且对称设于音圈210的相对两侧。由此设置，当骨架220上形成有一个凸部2221时，主振膜230上总有一个第一安装槽2311能够与凸部2221配合，从而便于主振膜230的定位安装。在其他实施例中，骨架220上对称设有两个凸部2221，两个第一安装槽2311即可分别对应于两个凸部2221。
具体地，参阅图6所示，主振膜230具有振膜连接部231、振膜折环部232以及振膜固定部233，振膜折环部232分别连接于振膜连接部231和振膜折环部232，振膜连接部231连接于骨架220；振膜固定部233开设有第二安装槽2331，盆架100至少部分嵌设于第二安装槽2331内。
由此设置，在组装主振膜230和盆架100时，可以将盆架100的部分结构插设于第二安装槽2331内，从而实现盆架100与主振膜230之间的定位。进一步地，振膜固定部233大致为矩形，且振膜固定部233的四角各设置有一个第二安装槽2331，在主振膜230与盆架100连接时，盆架100与四个第二安装槽2331相配合，从而实现盆架100与主振膜230的安装定位。在其他实施例中，第二安装槽2331也可以设置多个，例如两个、三个或四个以上，且多个第二安装槽2331沿振膜固定部233的外轮廓均匀设置。
进一步地，参阅图5和图6所示，磁路组件300包括磁部组、极芯组以及底板350，磁部组固定于底板350上，极芯组设于磁部组远离底板350的一侧；极芯组包括主极芯330以及环绕主极芯330设置的副极芯340，副极芯340自其边缘向外凸设有定位部341，盆架100的外壁上开设有定位槽110，定位部341与定位槽110相适配。
具体参阅图7所示，在本实施例中，副极芯340具有极芯本体342以及凸设与极芯本体342外壁的定位部341，极芯本体342与主极芯330相配合形成极芯间隙，磁部组包括主磁部310以及环绕主磁部310设置的副磁部320，且主磁部310与副磁部320间隔设置形成连通于极芯间隙的磁部间隙，音圈210可动地设于磁部间隙和极芯间隙内；组装本实施例的扬声器模组10时，副极芯340可以通过定位部341与盆架100的定位槽110相适配，同时使扬声器模组10具有更为紧凑的结构。
可以理解地是，在本实施例中，副磁部320设置有多个，主磁部310大致为矩形，多个副磁部320分别沿主磁部310的轮廓环绕主磁部310设置，在其他实施例中，副磁部320也可以为整体结构，并环绕主磁部310设置。在本实施例中，副极芯340为整体结构，并环绕主极芯330设置，在其他实施例中，副极芯340也可以设置为分体结构。
进一步地，在一实施例中，定位槽110的数目为两个，且两个定位槽110对称设于盆架100的相对两侧。
由此设置，当副极芯340具有一个定位部341时，总有一个定位部341可以对应于定位槽110，从而便于副极芯340的安装定位；当副极芯340具有两个定位部341，且两个定位部341对称设于极芯本体342的相对两侧时，盆架100与副极芯340可以通过两组定位槽110和定位部341进行定位。
参阅图5和图6所示，在一实施例中，振动组件200还包括副振膜260，副振膜260设于骨架220远离主振膜230的一侧，且副振膜260至少部分罩设于柔性连接件240远离主振膜230的一侧。
在本实施例的扬声器模组10中，通过在骨架220远离主振膜230的一侧设置副振膜260，副振膜260可以与主振膜230相配合，以提高骨架220的移动平稳性，振动组件200的振动稳定性得以提高。
具体在一实施例中，平衡件250为可固化粘合剂或可固化胶。在组装本扬声器模组10时，根据焊盘部244的具体质量在远离焊盘部244一侧设置对应质量的平衡件250，待平衡件250固化之后，平衡件250可以平衡焊盘部244的重量，平衡件250可以根据实际情况使用对应密度的胶，以满足扬声器模组10的配重需求，操作便捷。
在其他实施例中，平衡件250也可以由固体材料制成，并可拆卸连接于骨架220，在组装扬声器模组10时，可以根据焊盘部244的实际重量安装对应的平衡件250，从而满足扬声器模组10的配重需求；具体地，平衡件250与骨架220可以采用例如粘接、卡接、焊接、螺钉连接、插接等可拆卸连接方式进行连接，从而便于平衡件250的拆装。
