其中，第二振动系统3的弹性连接件31的一端与振子组件32连接，弹性连接件31的另一端与固定组件连接。也就是说，弹性连接件31的另一端可以与支架4连接，也可以与磁路系统1连接。需要进行说明的是，支架4可以为独立于磁路系统1设置的单独部件，支架还可以由磁路系统1的一部分延伸形成，即支架还可以与磁路系统1形成为一体成型件，再或者，支架4是由磁路系统1延伸出的一部分以及注塑到磁路系统上的塑胶材料件(盆架5)共同形成，可以根据实际的设计和使用需求选择设置，本发明对此不做具体限制。
例如，如图16所示，磁路系统1可以包括边磁部12，边磁部12的边导磁板122包括沿第二方向延伸的第一板体1221和沿第一方向延伸的第二板体1222，振动发声单体100的盆架5为塑胶材料件，盆架5与边导磁板122一体注塑成型，盆架5与第二板体1222连接，振动发声单体100的盆架5形成为支架4。其中，弹性连接件31的一端与振子组件32连接，弹性连接件31的另一端与振动发声单体100的支架4一体注塑成型。
可以理解的是，通常扬声器的磁路系统1的一部分磁场用于驱动音圈22振动发声，本发明通过在磁路系统1中设置与第一振动系统2对应的磁间隙1a，且磁路系统1还与第二振动系统3的驱动线圈322对应设置，节省一套磁路系统1，降低生产成本，此外还可以节省一套磁路系统1占用的装配空间，从而可以满足振动发声单体100的小型化和轻薄化设计。
而且，第二振动系统3中的弹性连接件31的两端分别与振子组件32和固定组件相连，振子组件32和固定组件均为振动发声单体100的零部件，由此，振动发声单体100可以形成为一个独立的功能单元，即，当振动发声单体100可以作为一个完整且独立的功能单元固定于振动发声模组200的壳体201内，当振动发声模组200的型号发生变化时，仅通过调整其壳体201的尺寸和外形即可，无需对振动发声单体100进行改变，由此可以实现振动发声单体100的模块化和标准化设计，大大提升了振动发声单体100的适用性。

在图12-图13所示的具体示例中，支撑架133可以形成为板状结构，支撑架133的一端与本体部131连接，支撑架133的另一端沿第一方向朝向远离本体部131的方向延伸，由此，支撑架133可以限定出与弹性连接件31的安装空间，方便弹性连接件31的安装和固定。可选地，支撑架133与本体部131可以形成为一体成型结构，例如一体冲压件等，支撑架133与本体部131还可以形成为分体结构，支撑架133与本体部131可以通过焊接连接的方式固定在一起。可选地，支撑架133与本体部131可以由相同的材质组成，支撑架133与本体部131还可以由不同材质形成。例如，本体部131可以由高导磁材料(例如钴合金材料)制成，支撑架133可以由金属材质、塑料材质等组成。
在本发明的一个具体实施例中，本体部131可以形成为方形结构，支撑架133为两个且分别设于本体部131的对角位置，由此可以使两个弹性连接件31形成为对应安装结构，使得振子组件32的受力更加平衡，提升第二振动系统3的运行平稳性。
如图12-图13所示，在本发明的一个实施例中，弹性连接件31设有沿第二方向延伸的第一弹性连接部311和沿第三方向延伸的第二弹性连接部312，第三方向分别与第一方向和第二方向垂直，其中，第一弹性连接部311和第二弹性连接部312中的一个与支撑架133连接，第一弹性连接部311和第二弹性连接部312中的另一个与配重块321连接。

如图5-图6所示，在本发明的一些实施例中，第一子中心磁铁111至少为三个，相邻的两个第一子中心磁铁111间隔设置可以形成间隔部1b，驱动线圈322的数量与间隔部1b的数量相同，且驱动线圈322的中心孔与间隔部1b一一对应设置。具体而言，驱动线圈322可以形成为扁平状，驱动线圈322的两个长边3221设于中心孔的相对两侧，驱动线圈322的数量与间隔部1b的数量相同，即可以确保相邻的两个第一子中心磁铁111之间均设有一个驱动线圈322。由此，通过上述设置，每个驱动线圈322对应于一对间隔设置的第一子中心磁铁111，第一长边3221和第二长边3221可以充分切割磁感线，由此可以提升振子组件32的振动效果。
在本发明的一个具体示例中，驱动线圈322还可以包括相对设置的两个短边3222，两个短边3222设于长边3221的长度方向的两侧，每个短边3222的两端分别与长边3221连接，由此，两个短边3222和两个长边3221共同配合限定出中心孔，沿第一方向，每个中心孔与每个间隔部1b一一对应设置。

可选地，驱动线圈322可以为多个，镂空孔132为一个，镂空孔132与多个驱动线圈322对应设置，由此可以简化镂空孔132的加工程序，提升加工效率。可选地，驱动线圈322可以为多个，镂空孔132也可以设置多个，多个镂空孔132与多个驱动线圈322一一对应设置，由此可以相对减小导磁轭13的开孔面积，从而可以不仅提升导磁轭13的结构强度，还可以提升导磁轭13的聚磁效果。
在本发明的一些实施例中，位于两端位置的第一子中心磁铁111之间的其他第一子中心磁铁111沿第一方向的投影均位于镂空孔132的边缘内侧，由此可以确保穿过镂空孔132的磁感线的数量，从而可以确保第二振动系统3的振动效果。

在本发明的一些实施例中，中心磁部11还包括中心导磁板113，多个第一子中心磁铁111和第二子中心磁铁112远离第二振动系统3的一侧均与中心导磁板113连接，导磁轭13包括本体部131和设于本体部131的镂空孔132，边磁铁121和第二子中心磁铁112均设于本体部131，沿第一方向，镂空孔132与驱动线圈322至少部分相对设置。
具体而言，中心导磁板113不仅可以起到聚集磁感线的作用，还可以将多个第一子中心磁铁111和第二子中心磁铁112装配在一起。其中，边磁铁121和第二子中心磁铁112均可固定于导磁轭13的本体部131，由此可以通过导磁轭13对中心磁部11和边磁部12进行支撑，而且还可以起到聚磁的效果，可以确保对应第一振动系统2的磁场强度。导磁轭13的本体部131上设置镂空孔132，镂空孔132可以与部分驱动线圈322相对，也可以与整个驱动线圈322相对，由此可以确保驱动线圈322能够顺利地切割磁感线，从而可以确保第二振动系统3的振动效果。
在本发明的一些实施例中，多个第一子中心磁铁111沿第一方向的投影均可以位于镂空孔132的边缘内侧，由此可以确保穿过镂空孔132的磁感线的数量，从而可以确保第二振动系统3的振动效果。
进一步地，沿第一方向，多个第一子中心磁铁111均延伸至镂空孔132中，由此可以减小中心磁部11与驱动线圈322的间距，从而可以增大作用于驱动线圈322的磁感线强度，进而可以提升第二振动系统3的振动效果。
进一步地，驱动线圈322可以为多个，镂空孔132为一个，镂空孔132与多个驱动线圈322对应设置，由此可以简化镂空孔132的加工程序，提升加工效率。当然，驱动线圈322可以为多个，镂空孔132也可以设置多个，多个镂空孔132与多个驱动线圈322一一对应设置，由此可以相对减小导磁轭13的开孔面积，从而可以提升导磁轭13的聚磁效果和结构强度。

如图1、图5和图9所示，振动发声单体100包括：磁路系统1、第一振动系统2和第二振动系统3。
其中，第一振动系统2和第二振动系统3分别设于磁路系统1的相对两侧。磁路系统1包括导磁轭13和设于导磁轭13的中心磁部11和边磁部12，边磁部12设于中心磁部11的外侧且中心磁部11和边磁部12间隔设置限定出磁间隙1a。
中心磁部11包括三个第一子中心磁铁111、两个第二子中心磁铁112和中心导磁板113，三个第一子中心磁铁111沿第二方向(水平x方向)间隔分布，两个第二子中心磁铁112设于三个第一子中心磁铁111的第三方向(水平y方向)的两侧，每个第一子中心磁铁111和第二子中心磁铁112远离第二振动系统3的一端均与中心导磁板113连接，相邻的两个第一子中心磁铁111间隔设置形成间隔部1b。边磁部12包括边磁铁121和设于边磁铁121远离第二振动系统3一侧的边导磁板122，导磁轭13包括本体部131和设于本体部131的镂空孔132，边磁铁121和第二子中心磁铁112均设于本体部131。沿第一方向(竖直z方向)，多个第一子中心磁铁111与镂空孔132相对。其中，边磁铁121、第一子中心磁铁111和第二子中心磁铁112均沿第一方向充磁，沿第二方向，相邻的边磁铁121与第一子中心磁铁111之间以及相邻的两个第一子中心磁铁111之间的充磁方向均相反，沿第三方向，相邻的边磁铁121与第二子中心磁铁112之间充磁方向均相反。

第二振动系统3沿第二方向振动，第二振动系统3包括弹性连接件31和振子组件32，导磁轭13的本体部131形成方形结构，本体部131的一对对角位置设有支撑架133，支撑架133形成为板状结构，支撑架133的一端与本体部131连接，支撑架133的另一端沿第一方向朝向远离本体部131的方向延伸，弹性连接件31的两端分别与振子组件32和支撑架133连接，由此磁路系统1可以将振子组件32进行悬置，振子组件32包括配重块321和设于配重块321的两个驱动线圈322，每个驱动线圈322均具有相对设置的两个长边3221和相对设置的两个短边3222，两个短边3222设于长边3221的长度方向的两侧，每个短边3222的两端分别与长边3221连接，由此，两个短边3222和两个长边3221共同配合限定出中心孔，沿第一方向，每个中心孔与每个间隔部1b一一对应设置，两个长边3221分别与相邻的两个第一子中心磁铁111相对设置。
如图1-图3所示，根据本发明的一些实施例，配重块321靠近磁路系统1的一侧设有装配槽321a，驱动线圈322嵌设于装配槽321a内，由此可以使得振子组件32的结构更加紧凑。可选地，装配槽321a内可以设置固定胶，驱动线圈322可以通过固定胶固定于装配槽321a内。需要进行说明的是，配重块321的结构设计并不仅限于此。例如，配重块321也可以不设置装配槽321a，驱动线圈322可以粘接在配重块321的外表面。
如图4和图7所示，根据本发明的一些实施例，磁间隙1a可以为多个，多个磁间隙1a同轴设置且由内向外依次间隔分布，音圈22也可以为多个，多个音圈22与多个磁间隙1a一一对应设置，由此，第一振动系统2可以形成为多个音圈22同步驱动振膜组件21的结构，从而可以提升第一振动系统2的发声灵敏度和响度，提升振动发声单体100的发声效果。
在图7所示的具体实施例中，磁路系统1包括中心磁部11和边磁部12，中心磁部11包括第一子中心磁部11a和第二子中心磁部11b，第二子中心磁部11b设于第一子中心磁部11a的外侧并与第一子中心磁部11a间隔设置形成第一子磁间隙1c，边磁部12设于第二子中心磁部11b的外侧并与第二子中心磁部11b间隔设置形成第二子磁间隙1d，第一振动系统2包括振膜组件21、第一子音圈22a和第二子音圈22b，第一子音圈22a和第二子音圈22b的一端分别与振膜组件21连接，第一子音圈22a的另一端插设于第一子磁间隙1c，第二子音圈22b的另一端插设于第二子磁间隙1d。由此，第一振动系统2可以形成为双音圈22同步驱动一个振膜组件21的结构，由此可以提升磁路系统1的磁场利用率，进而可以提升振动发声单体100的发声灵敏度。驱动线圈322具有相对设置的两个连接边，沿第一方向，两个连接边分别与第一子中心磁部11a和第二子中心磁部11b相对设置。当然，两个连接边沿第一方向也可以分别与第二子中心磁部11b和边磁部12相对设置。
需要进行说明的是，上述多个音圈22同步驱动振膜组件21的结构中，音圈22的设置数量可以根据实际的使用需求选择设置，本发明对此不作限定。
如图7所示，在本发明的一些实施例中，第一子中心磁部11a可以包括第一中心磁铁114，第二子中心磁部11b可以包括设于第一中心磁铁114外周的第二中心磁铁115，边磁部12可以包括设于第二子中心磁部11b外周的边磁铁121，第一中心磁铁114、第二中心磁铁115和边磁铁121均沿第一方向(竖直z方向)充磁，沿第二方向(水平x方向)，相邻的第一中心磁铁114与第二中心磁铁115之间以及相邻的第二中心磁铁115与边磁铁121之间的充磁方向相反。由此，通过上述设置，可以使得第一子音圈22a和第二子音圈22b充分切割第一子磁间隙1c和第二子磁间隙1d内的磁感线，还可以使得驱动线圈322充分切割相邻的第一子中心磁部11a和第二子中心磁部11b之间的磁感线，可以确保振动发声单体100的发声和振动效果。
可选地，如图4所示，第一中心磁铁114可以设置为一块，第二中心磁铁115包括四块且设于第一中心磁铁114的四周，边磁铁121也包括四块并设于第二子中心磁部11b的外侧，四个第二中心磁铁115与四个边磁铁121一一对应设置。
如图15所示，在本发明的一些实施例中，第一中心磁铁114的第二方向(例如水平x方向)两端的第二中心磁铁115为第一磁铁115a，第一中心磁铁114的第三方向(例如水平y方向)两端的第二中心磁铁115为第二磁铁115b，第三方向分别垂直于第一方向(例如竖直z方向)和第二方向，第一磁铁115a的体积大于第二磁铁115b的体积。可以理解的是，由于驱动线圈322的长边3221沿第三方向延伸，因此，作用于驱动线圈322的磁场主要来自第一中心磁铁114和位于第一中心磁铁114的第二方向两侧的第二中心磁铁115(第一磁铁115a)，通过设置第一磁铁115a的体积大于第二磁铁115b的体积，由此可以增大作用于驱动线圈322的磁场强度，从而可以提升振动发声单体100的振感。
进一步的，如图7、图11和图14所示，第二子中心磁部11a还包括设于第二中心磁铁115靠近振膜组件211一侧的第二中心导磁板113b，第二中心导磁板113b形成封闭环形结构，由此可以方便对第一磁铁和第二磁铁进行集中装配，提升装配效率。
如图7和图14所示，在本发明的一些实施例中，导磁轭13可以包括本体部131和设于本体部131的镂空孔132，沿第一方向(例如竖直z方向)，镂空孔132与驱动线圈322至少部分相对设置，边磁部12和第二子中心磁部11b均设于本体部131，第一子中心磁部11a包括第一中心磁铁114和第一中心导磁板113a，第一中心导磁板113a可以包括支撑板1131a和设于支撑板外侧的延伸板1132a，延伸板1132a的至少部分沿第一方向延伸，延伸板1132a的两端分别与支撑板1131a和本体部131连接，支撑板1131a与镂空孔132相对设置，第一中心磁铁114设于支撑板1131a。
具体而言，导磁轭13可以用于支撑第一子中心磁部11a、第二子中心磁部11b和边磁部12。其中，第二子中心磁部11b和边磁部12设于导磁轭13的本体部131，由于第一中心导磁板113a的延伸板1132a与本体部131连接，因此，导磁轭13通过延伸板1132a支撑第一子中心磁部11a。可以理解的是，由于导磁轭13沿第一方向设有与驱动线圈322相对的镂空孔132，其中，镂空孔132可以与部分驱动线圈322相对，也可以与整个驱动线圈322相对，由此可以确保驱动线圈322能够顺利地切割磁感线，从而可以确保第二振动系统3的振动效果。
可选地，支撑板1131a可以水平延伸，第一中心磁铁114设于支撑板1131a靠近镂空孔132的一侧，延伸板1132a可以竖直延伸，延伸板1132a的两端分别连接于支撑板1131a和本体部131。
如图11所示，在本发明的一些实施例中，沿分别垂直于第一方向和第二方向的第三方向，延伸板1132a位于支撑板1131a的相对两侧，第二子中心磁部11b与支撑板1131a间隔设置限定出部分第一子磁间隙1c。具体而言，第二方向和第三方向可以位于同一个水平面内，例如，第一方向可以为竖直z方向，第二方向可以为水平x方向，第三方向可以为水平y方向。其中，延伸板1132a可以为两个，两个延伸板1132a可以设于支撑板1131a的第三方向的两侧，由此可以将支撑板1131a与导磁轭13连接在一起，结构设计比较简单。其中，第二子中心磁部11b可以与支撑板1131a间隔设置限定出一部分第一子磁间隙1c，第二子中心磁部11b还可以与第一中心磁铁114的第二方向的两侧间隔设置限定出另一部分第一子磁间隙1c。
如图15所示，在本发明的一些实施例中，第二子中心磁部11b可以包括设于第一中心磁铁114外周的第二中心磁铁115，第一子中心磁部11a的第三方向(例如水平y方向)两侧的第二中心磁铁115设于本体部131，第一子中心磁部11a的第二方向(例如水平x方向)两侧的第二中心磁铁115沿第一方向与镂空孔132相对，由此可以增大与镂空孔132相对设置的第二中心磁铁115的面积，从而可以确保作用于驱动线圈322上的磁感线的数量，确保第二振动系统3的振动效果。
如图14所示，在本发明的一些实施例中，第二子中心磁部11b可以包括设于第二中心磁铁115远离本体部131一侧的第二中心导磁板113b，第二中心导磁板113b形成为环状结构并套设于支撑板1131a的外侧，由此，位于第一中心磁铁114外周的第二中心磁铁115均与第二中心导磁板113b远离振膜组件21的一侧连接，位于第一子中心磁部11a第三方向两侧的第二中心磁铁115设于本体部131，位于第一子中心磁部11a第二方向两侧的第二中心磁铁115底部与镂空孔132沿第一方向相对，通过上述设置，第二中心导磁板113b可以将位于第一子中心磁部11a第二方向两侧的第二中心磁铁115悬空设置，结构设计简单巧妙，不仅可以满足第一子音圈22a的磁场力要求，还可以确保作用于驱动线圈322上的磁感线数量，确保第二振动系统3的振动效果。
在本发明的一些实施例中，第一中心磁铁114和位于第一子中心磁部11a的第二方向(例如水平x方向)两侧的第二中心磁铁115沿第一方向(例如竖直z方向)的投影位于镂空孔132的边缘内侧，由此可以确保穿过镂空孔132的磁感线的数量，从而可以确保第二振动系统3的振动效果。
进一步地，沿第一方向，第一中心磁铁114和位于第一子中心磁部11a的第二方向两侧的第二中心磁铁115均延伸至镂空孔132中，由此可以减小第一子中心磁部11a和第二子中心磁部11b与驱动线圈322之间的间距，从而可以增大作用于驱动线圈322的磁场强度，进而可以提升第二振动系统3的振动效果。
在本发明的一个具体实施例中，第一中心导磁板113a与导磁轭13形成为一体成型结构，由此可以简化磁路系统1的结构设计，简化装配流程。例如，第一中心导磁板113a与导磁轭13可以形成为一体冲压件。当然可以理解的是，第一中心导磁板113a与导磁轭13也可以形成为分体件，第一中心导磁板113a的延伸板1132a与导磁轭13的本体部131可以通过激光焊接的方式装配在一起。

可以理解的是，在一些实施例中，在第一振动系统2的振膜211固定在固定组件的第一端端面的情况下，固定组件第一端的端面固定振膜211后再与壳体201的内壁连接。或者，在一些其他的实施例中，固定组件第一端的端面依次连接有振膜211、前盖，前盖作为防护件，在此情况下，固定组件的第一端固定振膜211和前盖后再与壳体201的内壁连接。
通常情况下，振动发声单体设于振动发声模组200的壳体201内，将壳体201内部空间分隔为前声腔和后声腔，前声腔与壳体201上的出声口连通以将声音导出，后声腔与振膜211背面的空间连通用于调整产品低频性能。
