参阅图5、图7和图10所示，在本实施例中，第一磁部151与第二磁部152一体成型。具体地，第一磁部151和第二磁部152可以通过焊接形成。在其他实施例中，第一磁部151和第二磁部152也可以通过可拆卸的连接方式进行连接固定。
具体地，第一磁路组件132包括环绕第一磁部151设置的外磁部组，外磁部组与第一磁部151间隔设置以形成第一磁间隙1325，且外磁部组设于支撑部111靠近第一振动组件131的一侧，第一振动组件131至少部分可活动地设于第一磁间隙1325内。
参阅图6和图10所示，在一实施例中，外磁部组包括两个第一外磁部1322和两个第二外磁部1323，两个第一外磁部1322对称设于第一磁部151的其中相对的两个侧边，两个第二外磁部1323对称设于第一磁部151的另外两个相对的侧边，两个第一外磁部1322和两个第二外磁部1323围合形成大致为矩形的结构，并与第一磁部151间隔设置，从而形成环形的第一磁间隙1325，以实现驱动第一振动组件131的功能。
在其他实施例中，第一外磁部1322和第二外磁部1323也可以首尾相连并形成闭合的环形结构，并与第一磁部151相配合以形成第一磁间隙1325。在一些实施例中，第一磁部151也可以设置为例如多边形或弧形的结构，通过设置与第一磁部151相对应的外磁部组，以形成对应于第一振动组件131的第一磁间隙1325。
进一步地，第一磁路组件132还包括盖设在外磁部组远离支撑部111一侧的第一副极芯1321，主磁体150包括盖设于第一磁部151的第一主极芯153，第一主极芯153与第一副极芯1321相对且间隔设置。
参阅图6所示，第一主极芯153与第一副极芯1321间隔设置以形成第一极芯间隙1326，第一磁间隙1325和第一极芯间隙1326沿第二磁部152至第一磁部151的方向依次设置并连通，且第一主极芯153和第一副极芯1321为导磁材料制成，由此设置，在第一磁路组件131驱动第一振动组件131振动的过程中，以使第一振动组件131位于第一磁间隙1325和第一极芯间隙1326中的部分能够稳定地移动。
具体地，第二磁路组件142包括固定在第一磁部151上并环绕设第二磁部152设置的中磁部组，中磁部组与第二磁部152间隔设置以形成第二磁间隙1426，且中磁部组设于第一磁部151靠近第二振动组件141的一侧，且第二振动组件141至少部分可活动地设于第二磁间隙1426内。
参阅图7和图10所示，在一实施例中，中磁部组包括两个第一中磁部1422和两个第二中磁部1423，第二磁部152在第一磁部151上的投影大致为矩形，两个第一中磁部1422对称设于第二磁部152的其中相对的两个侧边，两个第二中磁部1423对称设于第二磁部152的另外两个相对的侧边，两个第一中磁部1422和两个第二中磁部1423围合形成大致为矩形的结构，并与第二磁部152间隔设置，从而形成环形的第二磁间隙1426，以实现驱动第二振动组件141的功能。
在其他实施例中，第一中磁部1422和第二中磁部1423也可以首尾相连并形成闭合的环形结构，并与第二磁部152相配合以形成第二磁间隙1426。在一些实施例中，第二磁部152也可以设置为例如多边形或弧形的结构，通过设置与第二磁部152相对应的中磁部组，以形成对应于第二振动组件141的第二磁间隙1426。
进一步地，第二磁路组件142还包括盖设在中磁部组远离第一磁部151一侧的第二副极芯1421；主磁体150还包括盖设于第二磁部152的第二主极芯154，第二主极芯154与第二副极芯1421相对且间隔设置。
参阅图7所示，第二磁间隙1426和第二极芯间隙1427沿第一磁部151至第二磁部152的方向依次设置并连通，且第二主极芯154和第二副极芯1421为导磁材料制成，由此设置，在第二磁路组件142驱动第二振动组件141振动的过程中，以使第二振动组件141位于第二磁间隙1426和第二极芯间隙1427中的部分能够稳定地移动。
参阅图6、图10和图13所示，第一振动组件131包括相接的第一振膜1311和第一音圈1312，第一振膜1311与盆架120围合并覆盖盆架120远离上夹板110的一侧，第一音圈1312固定于第一振膜1311靠近第二振动组件141的一侧，且第一音圈1312至少部分悬置于第一磁间隙1325内。
请继续参阅图7、图10和图14所示，第二振动组件141包括相接的第二振膜1411和第二音圈1412，第二振膜1411盖设于上夹板110并与第二磁部152相对且间隔设置，第二振膜1411的周缘与支撑部111固定，第二音圈1412固定于第二振膜1411靠近第二磁部152的一侧，且第二音圈1412至少部分悬置于第二磁间隙1426内。
进一步地，参阅图10和图13所示，第一振动组件131还包括第一球顶1313，第一球顶1313的相对两侧分别连接于第一音圈1312和第一振膜1311。
由此设置，当第一磁路组件132驱动第一音圈1312移动的过程中，第一音圈1312的驱动力作用于第一球顶1313上，并进而驱动第一振膜1311移动，通过设置第一球顶1313连接第一振膜1311和第一音圈1312，可以增大第一振膜1311与第一球顶1313之间的接触面积，从而避免第一音圈1312驱动第一振膜1311的过程中损坏第一振膜1311。
进一步地，参阅图10和图14所示，第二振动组件141还包括第二球顶1413，第二球顶1413的相对两侧分别连接于第二音圈1412和第二振膜1411。
由此设置，当第二磁路组件142驱动第二音圈1412移动的过程中，第二音圈1412的驱动力作用于第二球顶1413上，并进而驱动第二振膜1411移动，通过设置第二球顶1413连接第二振膜1411和第二音圈1412，可以增大第二振膜1411与第二球顶1413之间的接触面积，从而避免第二音圈1412驱动第二振膜1411的过程中损坏第二振膜1411。
进一步地，参阅图4、图9和图10所示，延伸部112上还贯穿开设有分别连通于第一磁间隙1325和第二磁间隙1426的泄压槽1121。
可以理解地是，第一振膜1311盖设于盆架120上并围合形成第一后腔121，第二振膜1411盖设于上夹板110上并围合形成第二后腔122。当第一振动组件131和第二振动组件141振动的过程中，第一后腔121和第二后腔122内的气压便会发生改变，通过在上夹板110上开设泄压槽1121，当第一振膜1311和第二振膜1411发生振动时，第一后腔121和第二后腔122内的气体便可以通过泄压槽1121与进行气体交换，从而平衡扬声器单体100内的气压。
进一步地，参阅图4和图10所示，延伸部112开设有多个泄压槽1121，且多个泄压槽1121沿环绕延伸部112等间距设置。
参阅图10所示，延伸部112的轮廓大致为矩形，泄压槽1121设置有四个，且分别位于延伸部112的四个顶角处；当第一发声机构130和第二发声机构140运行的过程中，第一后腔121和第二后腔122内的气体可以通过位于延伸部112的四个顶角处的泄压槽1121进行气体交换。
参阅图11所示，在一实施例中，延伸部112环绕第一磁部151设置，且延伸部112远离支撑部111的一端抵接并固定于第一主极芯153。
组装本实施例的扬声器单体100时，可以首先将延伸部112远离支撑部111的一端与第一磁部151固定连接，延伸部112与第一磁部151固定之后，可以在延伸部112内部形成的空间内安装第二发声机构140，参阅图11所示的摆放状态，主磁体150可以在第二发声机构140的底部承托第二发声机构140；之后将上夹板110与主磁体150一同与盆架120连接，进而安装第一发声机构130。具体地，上夹板110与主磁体150的固定方式包括但不限于粘接、销钉连接、卡接、螺钉连接等，优选为焊接连接，采用焊接连接的上夹板110和主磁体150加工便捷，固定牢固。
参阅图12所示，在另一实施例中，延伸部112抵接并固定于第一磁部151远离第一主极芯153的一侧。
组装本实施例的扬声器单体100时，可以首先将延伸部112远离支撑部111的一端与第一主极芯153固定连接，参阅图12的摆放状态，第一主极芯153可以承托在主磁体150的底部，从而便于安装第一发声机构130和第二发声机构140，安装便捷。具体地，上夹板110与第一主极芯153的固定方式包括但不限于粘接、销钉连接、卡接、螺钉连接等，优选为焊接连接，采用焊接连接的上夹板110和第一主极芯153加工便捷，固定牢固。
参阅图3所示，在一实施例中，箱体200包括与相对且间隔设置的底壁210与顶壁220、以及环绕扬声器单体100的围壁230，请继续参阅图6和图8，底壁210与第一振动组件131之间间隔形成第一前声腔260，顶壁220与第二振动组件141之间间隔形成第二前声腔270；围壁230贯穿开设有出声孔，出声孔包括间隔设置的第一出声孔280和第二出声孔290，第一出声孔280与第一前声腔260连通，第二出声孔290与第二前声腔270连通，第一出声孔280与第二出声孔290位于扬声器单体100的同一侧。
可以理解地是，在本实施例的扬声器模组10中，扬声器单体100设置有朝向不同的第一发声机构130和第二发声机构140，由此能够朝向不同的方向发出声音，通过在箱体200上开设有与第一发声机构130对应的第一出声孔280和对应于第二发声机构140的第二出声孔290，第一发声机构130和第二发声机构140发出的声音可以由不同的出声孔发出，由此避免第一发声机构130和第二发声机构140发出的声音互相影响，扬声器模组10的发声效果得以进一步提高。
具体地，参阅图3和图8所示，围壁230包括环绕盆架120的内围壁231、与内围壁231间隔设置且绕设在内围壁231外周的外围壁232、以及连接在内围壁231与外围壁232之间的连接壁233；内围壁231与顶壁220及底壁210连接并将箱体200的内部空间分隔成收容扬声器单体100的容纳腔240以及位于外围壁232与内围壁231之间的辅助声腔250；出声孔依次贯穿外围壁232、连接壁233及内围壁231，内围壁231还开设有连接容纳腔240与辅助声腔250的通孔2311，通孔2311与出声孔间隔设置。
可以理解地是，使用本实施例的扬声器模组10时，扬声器单体100的第一后腔121和第二后腔122可以通过泄压槽1121和通孔2311与辅助声腔250进行气体交换，从而实现泄压的效果。同时，内围壁231内形成的容纳腔240也可以对扬声器单体100的安装进行定位，从而对扬声器单体100进行固定。
进一步地，通孔2311的数目有多个，且多个通孔2311均匀设于内围壁231上；泄压槽1121的数目有多个，且每一个泄压槽1121对应于一个通孔2311。可以理解地是，当扬声器单体100开设有多个泄压槽1121时，箱体200上开设有多个与泄压槽1121相对应的通孔2311，通过设置多个通孔2311对应于多个泄压槽1121，可以提高扬声器单体100泄压过程中的气体输送平稳性，从而提高扬声器模组10的泄压效果。
进一步地，参阅图8所示，第一出声孔280的孔径和/或第二出声孔290的孔径朝远离扬声器单体100的方向增大。
具体地，第一出声孔280在第一出声路径300上的横截面的面积逐渐增大，第二出声孔290在第二出声路径400上的横截面的面积逐渐增大，由此在第一出声孔280和第二出声孔290处形成类似“喇叭型”的结构，当声音在第一出声孔280和第二出声孔290内传输的过程中，由此结构可以提高扬声器模组10的发声响度，结构简单，发声效果得以进一步提高。
参阅图8所示，在本实施例中，第一出声孔280和第二出声孔290互不连通。由此设置，第一发声机构130发出的声音经由第一出声路径300从第一出声孔280输出，第二发声机构140发出的声音经由第二出声路径400从第二出声孔290输出，由此避免第一发声机构130和第二发声机构140发出的声音互相影响，从而提高扬声器模组10的发声效果。
在其他实施例中，第一出声孔280和第二出声孔290之间也可以互相连接，也就是说，第一出声孔280和第二出声孔290可以连接形成一个出声孔，也可以部分连通，由此可以优化出声孔的开口结构。
参阅图9和图10所示，在一实施例中，上夹板110开设有泄压槽1121，盆架120开设有第一外通路123，外磁部组开设有分别连通于泄压槽1121和第一外通路123的第二外通路1324；第一副极芯1321开设有第一内通路1424，中磁部组开设有分别连通于第一内通路1424和泄压槽1121的第二内通路1425；第二主极芯154开设有第三内通路1531，第二磁部152开设有连通于第三内通路1531和泄压槽1121的第四内通路1511；泄压通道160包括第一内通路1424、第二内通路1425、第三内通路1531、第四内通路1511、第一外通路123、第二外通路1324以及泄压槽1121。
具体地，本实施例的扬声器单体100在运行的过程中，第一振膜1311产生振动并使第一后腔121内产生气压变化，位于第一后腔121内的气体受到压力之后依次经由第三内通路1531和第四内通路1511输送至泄压槽1121，第二振膜1411产生振动并使第二后腔122内产生气压变化，位于第二后腔122内的气体受到压力之后依次经由第一内通路1424和第二内通路1425输送至泄压槽1121；输送至泄压槽1121的气体并经由第二外通路1324和第一外通路123排出扬声器单体100外，上述气体的输送路径组成泄压通道160；当第一振膜1311和第二振膜1411反向移动时，气体便沿泄压通道160进入第一后腔121和第二后腔122内以平衡气压。
进一步地，泄压通道160设置有多个，且沿环绕第一音圈1312的方向均匀设置在扬声器单体100上。参阅图10所示，第一磁部151大致为矩形，泄压通道160设置有四个，且分别位于第一磁部151的四个顶角处；当第一发声机构130和第二发声机构140运行的过程中，第一后腔121和第二后腔122内的气体可以通过位于扬声器单体100的四个顶角处的泄压通道160进行气体交换，从而实现泄压的作用，泄压效果好。
在其他实施例中，泄压通道160的具体数量也可以根据扬声器单体100的实际形状设置，具体数量可以为两个、三个或四个以上，设置有多个泄压通道160时，优选将多个泄压通道160沿扬声器单体100的外轮廓均匀设置，由此达到最优的泄压效果。
以上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。
