在本实施例中，立柱包括第一立柱231和第二立柱232，第一立柱231和第二立柱232分别固定连接于骨架21的两固定部212，第一立柱231和第二立柱232与骨架21共同支撑线圈22缠绕，同时使得振动激励器的整体结构更加稳定。在一些其他实施例中，也可以采用一组立柱或多组立柱与骨架21共同工作，在此不做限定，只要能达成稳定支撑线圈22并保障振动激励器正常运作即可。此外，在本申请的其他实施例中也可以设置多个线圈22，相应的设置对应数量的骨架21以及立柱等组件。
振动激励器还包括固定于立柱的远离固定部212的一端的弹簧片4，弹簧片4的边缘固定于壳体1。
具体的，弹簧片4包括若干定位孔，立柱远离固定部212的一端设置有若干定位凸块，弹簧片4与立柱通过定位孔和定位凸块扣合连接；和/或，弹簧片4包括固定孔43，立柱远离固定部212的一端设置有固定凹槽，螺栓44或铆钉穿过固定孔43并卡嵌至固定凹槽，振动激励器还包括穿过固定孔43并与固定凹槽固定连接的螺栓44或铆钉；和/或，弹簧片4和立柱通过焊接或粘接固定。在本实施例中，当弹簧片4与立柱通过螺栓44或铆钉连接时，分别在螺栓和立柱之间设置一个螺栓垫片441，用于保护弹簧片4和立柱结构，同时增大弹簧片4与立柱之间的接触面积，提高固定连接的稳定性，螺栓垫片441可以采用橡胶或与螺栓44或铆钉材质相同的金属制成。
在本实施例中，弹簧片4包括第一弹簧片41和第二弹簧片42，分别与两立柱远离固定部212的一端固定连接。弹簧片4采用镂空的螺旋片状设计，一方面，当弹簧片4和立柱采用铆钉连接或螺纹连接的方式固定连接时，铆钉或螺栓44也可以穿过弹簧片4的中心镂空部与立柱连接，不用额外开设固定孔43，使生产过程更加简便；另一方面可以减轻振动激励器的重量，使得振动激励器的整体结构更加轻便。在线圈22通电的情况下，定子组件3通过弹簧片4带动壳体1沿轴向方向同步振动。在本申请的其他实施例中，也可以采用其他类型的弹性件代替弹簧片4。
振动激励器还包括设置于收容腔14内且与外壳12间隔的配重块24，配重块24上开设有供立柱组23穿过的穿孔241，立柱嵌置于穿孔241并与配重块24固定连接。配重块24可以设置为与外壳12相适应的圆柱状，同时配重块24上设置有方便装配的凹陷部。
具体的，可以根据不同的使用需要，通过设置配重块24的重量来控制振动的强度，此外，配重块24一般使用密度较大的，例如铜、钨或其他合金等金属材质。通过线圈22通电后产生交变电流，切割磁钢32磁感线产生感应电动势，使得线圈22骨架21和立柱组23以及与骨架21和立柱组23固定连接的两配重块24产生上下往复振动，提供振感。
请参阅图4，外壳12的内侧朝向收容腔14内突出形成凸缘122，所述凸缘122的背离所述外壳12的一侧设置用于装配所述极芯31的装配槽123。
在本实施例中，设置两组分布在收容腔14内相对两侧壁的定子组件3，产生的磁场密度更高，振动效率也更高。在本实施例中，极芯31的一面和磁钢32采用粘接或焊接的方式固定连接，极芯31的另一面与凸缘122粘接或焊接固定连接。在极芯31和磁钢32、以及极芯31和凸缘122之间采用粘接的方式进行固定时，可以采用磁胶作为粘接工具，减少在振动过程中造成的磁介质损耗。凸缘122也为配重块24在振动时，在收容腔14内提供一定的缓冲空间。
在本实施例中，配重块24为振动过程提供振动量，壳体1用来固定定子组件3，以此保证震动***受到竖直方向往复驱动力。此外，两配重块24产生的振动方向和频率相同。
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。
