随着技术的发展，市面上已经出现内置有多个振膜的扬声器，在设置有多个振膜的扬声器中，通常使用骨架与多个振膜分别胶合并将多个振膜分隔开。
 技术问题
而骨架一般采用冲压加工制成，但是冲压加工会使骨架在弯折部位形成一定的折弯角，骨架在其弯折部位便无法与振膜有效地接合，从而导致振膜无法与骨架紧密贴合，进而影响振膜的安装牢固程度，扬声器的可靠性随之受到影响。

 本发明的实施方式
下面结合附图和实施方式对本申请作进一步说明。
参阅图1所示，本申请实施例提供了一种电子设备1，包括壳体20以及设于壳体20内的扬声器模组10。具体参阅图2所示，扬声器模组10包括盆架组件100、磁路组件200以及振动组件300，磁路组件200固定于盆架组件100上，磁路组件200至少部分穿设于振动组件300内；参阅图3所示，振动组件300包括音圈310以及第一振膜320，音圈310相对于磁路组件200是可活动的，磁路组件200用于驱动音圈310移动以使第一振膜320振动发声。
进一步地，振动组件300还包括柔性连接件330、骨架340以及第二振膜350：柔性连接件330与第一振膜320沿音圈310的移动方向依次间隔设置；请继续参阅图4和图5，柔性连接件330包括第一固定板331、第二固定板333以及分别连接于第一固定板331和第二固定板333的柔性部332；第一固定板331连接于盆架组件100，第二固定板333相对于第一固定板331是可活动的，且第二固定板333上开设有安装槽3331；骨架340连接于音圈310，且磁路组件200至少部分插设于骨架340内；请继续参阅图6，骨架340包括第一支撑部341、第二支撑部343以及分别连接于第一支撑部341和第二支撑部343的弯折部342，第一支撑部341连接于第一振膜320，第二支撑部343连接于第二固定板333；第二振膜350包括第一连接部351、第一固定部353以及分别连接于第一连接部351和第一固定部353的第一折环部352，且第一连接部351至少部分固定于安装槽3331内，并连接于第二支撑部343，第一固定部353连接于盆架组件100。
在本实施例的扬声器模组10中，柔性连接件330的第二固定板333连接于骨架340，第二固定板333上开设有用于连接第二振膜350的安装槽3331；在组装本实施例的扬声器模组10时，第二振膜350的第一连接部351与安装槽3331固定连接，并将第二振膜350的第一固定部353与盆架组件100固定连接，之后再将第二固定板333固定于骨架340上。相较于现有扬声器模组10的结构，本实施例的扬声器模组10通过在柔性连接件330上开设有安装槽3331以安装第二振膜350，第二振膜350可以通过安装槽3331与柔性连接件330固定连接，在保证扬声器模组10具有紧凑结构的前提下，进一步提高第一连接部351的结合面积，从而提高第二振膜350的牢固程度，扬声器模组10的可靠性得以提高。参阅图3所示，定义X方向为音圈310的移动方向。
在一实施例中，第一连接部351与安装槽3331的内壁粘接固定。组装本实施例的扬声器模组10时，可以在第一连接部351的外壁或安装槽3331的内壁涂布粘合胶，之后将第一连接部351与安装槽3331的内壁贴合，以使第二振膜350与柔性连接件330固定连接，再将柔性连接件330的第二固定板333与骨架340的第二支撑部343固定，从而保证第二振膜350与柔性连接件330之间的接合牢固度；相较于传统的扬声器模组，第二振膜350在与柔性连接件330连接之后再与骨架340接合，可以避免由于第二振膜350对应于骨架340在冲压加工中形成的弯折结构而导致第二振膜350与骨架340的重合程度降低，从而影响第二振膜350的牢固程度，使用效果好。
请继续参阅图7和图8，在一实施例中，第二固定板333具有第一连接面3332、第二连接面3334以及分别连接于第一连接面3332和第二连接面3334的中间面3333，第一连接面3332与第二支撑部343粘接固定，安装槽3331设于第二连接面3334上并贯穿中间面3333。
可以理解地是，组装本实施例的扬声器模组10时，参阅图8所示的摆放状态，将第二振膜350的第一连接部351自下而上与安装槽3331贴合，此时第一连接部351的顶面抵接于安装槽3331的内壁，并将第一连接部351固定于安装槽3331内，之后将第二固定板333的第一连接面3332与骨架340的第二支撑部343贴合，即可将第二振膜350的第一连接部351固定。
参阅图8中所示，在传统的扬声器模组中，第一连接部351设置的宽度尺寸有限，当第一连接部351直接与骨架340的第二支撑部343贴合时，弯折部342与第二支撑部343之间形成的弯折结构不能与第一连接部351紧密贴合，而在本实施例中的扬声器模组10中，通过在柔性连接件330的第二固定板333上开设安装槽3331，在不影响第二固定板333与骨架340之间的接合效果以及柔性连接件330外部尺寸的前提下，尽可能提高第一连接部351与第二固定板333之间的接触面积，从而提高第二振膜350与柔性连接件330之间的连接牢固程度。
具体在一实施例中，在音圈310的移动方向上，第一连接部351与第一连接面3332的间距为0.03mm。请继续参阅图9，定义L为第一连接部351与第一连接面3332之间的间距。由此设置，以使本扬声器模组10中的第二振膜350与柔性连接件330具有良好的连接牢固度的前提下，可以使柔性连接件330的第二固定板333具有紧凑的结构。在其他实施例中，L也可以根据实际情况设置对应的尺寸，在此不做唯一限定。
参阅图10所示的另一实施例，第二固定板333具有第一连接面3332、第二连接面3334以及分别连接于第一连接面3332和第二连接面3334的中间面3333，第一连接面3332与第二支撑部343胶合固定，安装槽3331设于第一连接面3332上并贯穿中间面3333，第一连接部351与第二支撑部343粘接固定。
参阅图10所示的摆放状态，在本实施例中，第一连接部351的下侧面以及第一连接部351远离第一折环部352一端的外侧面与安装槽3331的内壁贴合并固定连接，第二振膜350的上侧面可以与第二支撑部343贴合，并可以通过粘接固定连接，由此设置，可以进一步提高第二振膜350的连接牢固程度。
参阅图11所示，在又一实施例中，第二固定板333具有第一连接面3332、第二连接面3334以及分别连接于第一连接面3332和第二连接面3334的中间面3333，第一连接面3332与第二支撑部343粘接固定，安装槽3331开设于中间面3333上，第一连接部351插设于安装槽3331内。
可以理解地是，相较于上述实施例，本实施例中第二振膜350的第一连接部351插设于安装槽3331内，第一连接部351远离第一折环部352一侧的外侧面均与安装槽3331的内侧壁相贴合，从而使第二振膜350与第二固定板333之间具有更高的连接牢固度。
具体在一实施例中，第一振膜320包括第一膜体321、第二膜体323以及分别连接于第一膜体321以及第二膜体323的球顶322，球顶322连接于第一支撑部341，第一膜体321远离球顶322的一侧连接于磁路组件200，第二膜体323远离球顶322的一侧连接于盆架组件100。
参阅图3、图7和图8所示，磁路组件200驱动音圈310移动时，音圈310可以带动骨架340一同移动并进而带动球顶322振动，球顶322振动之后带动与其连接的第一振膜320和第二膜体323振动，从而实现扬声器模组10的发声。在其他实施例中，也可以取消设置的球顶322，并将第一膜体321、第二膜体323与第一支撑部341连接，从而实现第一振膜320的振动功能。
进一步地，参阅图12所示，球顶322上开设有第一连接槽3221和第二连接槽3222，第一膜体321至少部分设于第一连接槽3221内，第二膜体323至少部分设于第二连接槽3222内。
组装本实施例的第一振膜320时，第一膜体321通过第一连接槽3221于球顶322进行定位，第二膜体323通过第二连接槽3222与球顶322进行定位。
具体参阅图12所示的实施例，第一膜体321包括第二折环部3212以及分别连接于第二折环部3212的第二连接部3211以及第二固定部3213，第二连接部3211至少部分设于第一连接槽3221内，第二固定部3213与盆架组件100固定连接，第二连接部3211可相对于第二固定部3213活动；第二膜体323包括第三折环部3232以及分别连接于第三折环部3232的第三连接部3231以及第三固定部3233，第三连接部3231至少部分设于第二连接槽3222内，第三固定部3233与磁路组件200固定连接，第三连接部3231可相对于第三固定部3233活动。
参阅图2、图7和图8所示，具体在一实施例中，盆架组件100包括底板110、支板120以及外盆架130，底板110与外盆架130围合形成用于容纳磁路组件200和振动组件300的安装腔111，磁路组件200固定于底板110上，支板120连接于外盆架130并位于安装腔111内；第一振膜320和柔性连接件330分别设于支板120的相对两侧，第一固定板331以及第一固定部353均连接于支板120，第二膜体323远离球顶322的一侧连接于外盆架130。
参阅图6和图8所示，在一实施例中，第一支撑部341平行于第二支撑部343，且弯折部342垂直于第一支撑部341和第二支撑部343。参阅图8所示，骨架340的截面大致为“之”字型，由此设置，可以降低骨架340在支撑第一振膜320和第二振膜350时，在弯折部342与第一支撑部341和第二支撑部343连接部位的应力，从而提高骨架340的耐用性。
进一步地，参阅图6，弯折部342环绕磁路组件200设置，沿弯折部342的轮廓路径间隔且均匀开设有多个通孔3421。由此设置，在不改变骨架340整体结构的前提下，可以减轻骨架340的质量。
请继续参阅图4，在一实施例中，柔性连接件330还包括连接于第二固定板333的焊盘部334，第二支撑部343上开设有对应于焊盘部334的连接孔3432，音圈310具有引线（图中未标识），引线穿设于连接孔3432并与焊盘部334焊接。由此设置，可以实现音圈310的电路连接，从而实现扬声器模组10的发声作用。
具体在一实施例中，柔性连接件330的数目为两组，且两组柔性连接件330以磁路组件200为中心对称设置，每一组的柔性连接件330的第一固定板331均连接于盆架组件100，每一组的柔性连接件330的第二固定板333均连接于第二支撑部343。通过设置两组柔性连接件330，可以为骨架340和第二振膜350提供更为平衡的支撑效果。在其他实施例中，柔性连接件330也可以设置为四组，且四组柔性连接件330分别设于磁路组件200在水平面的四个方向上。
进一步地，参阅图3所示，骨架340内开设有容纳空间3431，磁路组件200包括磁部组、极芯组以及上磁轭250，磁部组固定于底板110上，极芯组沿X方向的相对两端分别连接于磁部组以及上磁轭250；磁部组包括主磁部210以及环绕主磁部210设置的外磁部，主磁部与外磁部之间形成磁部间隙，极芯组包括主极芯230以及环绕主极芯230设置的外极芯，主极芯与外极芯之间形成连通于磁部间隙的极芯间隙，音圈310可动地设于磁部间隙和/或极芯间隙内。
参阅图3所示，具体在一实施例中，主磁部210大致为矩形，外磁部包括两组第一外磁部221以及两组第二外磁部222，两组第一外磁部221分别设于主磁部210的相对两侧，两组第二外磁部222设于主磁部210另外的两侧。在其他实施例中，外磁部也可以设置为环形磁体。
在本实施例中，主极芯230大致为矩形，外极芯包括两组第一外极芯241以及两组第二外极芯242，两组第一外极芯241分别设于主极芯230的相对两侧，两组第二外极芯242设于主极芯230另外的两侧。在其他实施例中，外极芯也可以设置为环形磁体。
参阅图3所示的实施例中，第一外磁部221和第一外极芯241分别插设于骨架340内，主磁部210、第二外磁部222、主极芯230以及第二外极芯242设于容纳空间3431内。由此设置，可以使本扬声器模组10具有紧凑的结构，便于扬声器模组10在壳体20内的安装布置。
进一步地，磁路组件200还包括副磁部270，副磁部270设于主极芯230远离主磁部210的一侧；外磁部组还包括两组第三外磁部223和两组第四外磁部224，第三外磁部223设于第二外极芯242远离第二外磁部222的一侧，第四外磁部224设于第二外极芯242远离第一外磁部221的一侧。
在本实施例中，主磁部210、第一外磁部221以及第二外磁部222形成主磁部组，副磁部270、第三外磁部223以及第四外磁部224形成副磁部组，并且在X方向上，主磁部组和副磁部组分别设于主极芯230的两侧，通过主磁部组和副磁部组的配合，可以提升磁路组件200的磁场强度，从而提高扬声器模组10的性能。
进一步地，参阅图3和图12所示，磁路组件200还包括垫圈260，第二固定部3213、垫圈260以及上磁轭250沿X方向依次设置，且垫圈260分别抵接于第二固定部3213和上磁轭250。
由此设置，在本实施例的扬声器模组10中，垫圈260分别支撑上磁轭250和第二折环部3212，从而避免上磁轭250直接接触第二固定部3213而对第二固定部3213造成损伤。在一些实施例中，垫圈260可以选用橡胶、硅胶等柔性材料制成。在其他实施例中，垫圈260可以采用硬度低于第二固定部3213的材料制成，也可以避免损伤垫圈260。以上所述的仅是本申请的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本申请创造构思的前提下，还可以做出改进，但这些均属于本申请的保护范围。
