具体地，所述线圈组件2还包括铁芯23；所述第一线圈21绕设于所述铁芯23，所述第二线圈22绕设于所述第一线圈21与所述铁芯23。为聚集所述第一线圈21与所述第二线圈22在通电时产生的磁场，以增大与所述第一磁体31之间相互作用的驱动力，进而提升所述振动装置100的振动力度，提升用户使用体验，本申请中所述线圈组件2还包括所述铁芯23，所述第一线圈21与所述第二线圈22均绕设于所述铁芯23。
此外，所述第一弹性件12包括两个第一固定部121以及第一弹性连接部122，两个所述第一固定部121分别连接于所述内壳体13与所述外壳体11，所述第一弹性连接部122与所述第一固定部121呈折弯设置，以连接两个所述第一固定部121。所述第一弹性件12的具体结构形式可以为多种，包括不限于弹簧、弹片等，能够实现弹性复位功能即可，在此不作限定。本实施例中，所述第一弹性件12设置为弹片结构，其结构简单性能稳定使用效果好，具体地，所述第一弹性件12包括两个所述第一固定部121，两个所述第一固定部121分别与所述内壳体13以及所述外壳体11连接，以保障所述第一弹性件12连接的稳定性，再通过所述第一弹性连接部122连接两个所述第一固定部121，所述第一弹性连接部122在第一方向上弹性伸缩，即可实现所述内壳体13在所述外壳体11内沿第一方向上的弹性活动，满足使用需求。
此外，所述磁体结构3还包括配重块32，所述第一磁体31安装于所述配重块32；所述第二弹性件4连接所述配重块32与所述内壳体13。一方面为增强所述振动装置100的振动效果，另一方面为安装固定所述磁体结构3，所述第二弹性件4连接所述配重块32与所述内壳体13，以使得所述第二线圈22通电时，驱动所述第一磁体31带动所述配重块32在所述内壳体13内沿第二方向活动，而在所述第一线圈21通电时，驱动所述第一磁体31带动所述配重块32以及所述内壳体13在所述外壳体11内沿第一方向活动，满足使用需求。
具体地，所述内壳体13内在第二方向上的一侧通过所述第二弹性件4与所述配重块32连接，其在第二方向上的另一侧与所述配重块32之间设置有第一阻尼件123。在所述第二弹性件4驱动所述配重块32沿第二方向振动时，可能存在共振情况，影响振动体验，故本实施例中所述配重块32在第二方向上的两侧与所述内壳体13之间分别设置有所述第一阻尼件123与所述第二弹性件4，以通过所述第一阻尼件123在所述配重块32沿第二方向活动时，被压缩而起到缓冲效果，进而抑制共振，提升所述振动装置100的振动效果。
具体地，所述配重块32上开设有容置槽321，所述第一阻尼件123容置于所述容置槽321内。一方面便于所述第一阻尼件123安装放置，另一方面避免使用过程中所述第一阻尼件123与所述配重块32脱离影响正常功能，本实施例在所述配重块32上开设有所述容置槽321，以用于容置所述第一阻尼件123，满足上述需求。
此外，与所述第一弹性件12的设置方式相同，所述第二弹性件4也设置为弹片结构，结构简单性能稳定使用效果好，具体地，所述第二弹性件4包括两个第二固定部41以及第二弹性连接部42，两个所述第二固定部41分设于所述内壳体13与所述配重块32，所述第二弹性连接部42与所述第二固定部41呈折弯设置，以连接两个所述第二固定部41。两个所述第二固定部41分别与所述内壳体13以及所述配重块32连接，以保障所述第二弹性件4连接的稳定性，再通过所述第二弹性连接部42连接两个所述第二固定部41，所述第二弹性连接部42在第二方向上弹性伸缩，即可实现所述配重块32在所述内壳体13内沿第二方向上的弹性活动，满足使用需求。
此外，所述外壳体11与所述内壳体13在第一方向上的间隔处设置有第二阻尼件43。同样的，在所述第一弹性件12驱动所述内壳体13沿第一方向振动时，也可能存在共振情况，影响振动体验，故本实施例中所述内壳体13在第一方向上的两侧与所述外壳体11之间分别设置有一所述第二阻尼件43，以通过所述第二阻尼件43在所述内壳体13沿第一方向活动时，被压缩而起到缓冲效果，进而抑制共振，提升所述振动装置100的振动效果。
此外，位于所述线圈组件2在第三方向上的两侧均设置有一所述第一磁体31，且两个所述第一磁体31相对的一侧磁极相同。两个所述第一磁体31相对的一侧磁极相同，以使得所述线圈组件2通电时，两个所述第一磁体31能够产生相同方向的驱动力，进而提升所述振动装置100的振动力度，提升用户的使用体验。
此外，所述磁体结构3还包括沿第一方向设置于所述第一磁体31的两侧的第二磁体33，所述第二磁体33靠近所述第一磁体31一方的磁极与所述第一磁体31靠近所述线圈组件2一方的磁极相同。使得所述第二磁体33的磁场可顺着所述第一磁体31的磁场发散，如此，使得所述第一磁体31的磁场与所述第二磁体33的磁场融合后比所述第一磁体31自身的磁场强度强，进而提升所述线圈组件2通电后的磁驱动力，从而提升所述振动装置100的振动力度，提升振动体验。
具体地，每一所述第一磁体31在第一方向上的两侧分别设置有一所述第二磁体33。所述第二磁体33可绕所述第一磁体31的周侧布设，具体布设位置以及布设数量可不作限定，能够实现上述增强所述第一磁体31的磁场的作用即可，但普遍的，磁体一般为方形结构，故本申请中在所述第一磁体31沿第一方向上的两侧分别设置一所述第二磁体33，以形成一长形磁体组，便于结构布设。
此外，所述磁体结构3还包括导磁板34，在所述线圈组件2同侧的所述第一磁体31与所述第二磁体33固定于一所述导磁板34。一方面为固定上述长形磁体组，避免所述第一磁体31与所述第二磁体33之间磁力作用影响原有结构布置，进而避免影响所述振动装置100的功能，另一方面为进一步聚焦增强上述长形磁体组的磁场，以提升所述振动装置100的振动性能，本申请采用所述导磁板34对所述第一磁体31与所述第二磁体33进行固定，结构简单效果好。
