请参阅图9和图10，振动马达还包括设置在弹性件6远离连接部213的一侧的第一焊点60，连接部213和弹性件6通过在第一焊点60处焊接的方式固定连接，具体为在连接部213和弹性件6相接触之后，在弹性件6的第一焊点60处进行焊接以将连接部213和弹性件6固定在一起，实现支架组件2和弹性件6的固定连接。
请参阅图11至图14，在本实用新型的第三实施例中，骨架21还包括一端固定于支撑部212且另一端固定于弹性件6的立柱214，胶层22还包覆在立柱214的周侧和支撑部212的外侧。具体的，骨架21由主体部211、支撑部212和立柱214组成，立柱214和主体部211的形状相同，且立柱214由金属材料制成，立柱214和支撑部212通过焊接固定在一起。优选地，支撑部212设有定位槽，立柱214设有定位部，通过定位部和定位槽之间的配合，可以实现立柱214和支撑部212的快速定位，提升装配效率。根据实际需要，可以在支撑部212设置定位部，在立柱214设置定位槽；立柱214和支撑部212之间也可以通过胶粘固定。其中，立柱214与弹性件6之间的固定方式包括铆接固定、螺钉固定和焊接固定中的任一种，即支架组件2与弹性件6之间可以通过铆接固定、螺钉固定和焊接固定等方式固定连接。
请参阅图11，立柱214开设第三安装孔，振动马达还包括穿过弹性件6并固定于第三安装孔的第三铆钉70，使得立柱214与弹性件6之间铆接固定，即第三铆钉70可以锁紧胶层22和弹性件6，实现支架组件2和弹性件6的固定连接。
请参阅图12和图14，立柱214开设第三螺纹孔，振动马达还包括穿过弹性件6并与第三螺纹孔螺纹连接的第三螺钉80，使得立柱214与弹性件6之间螺钉固定，即第三螺钉80可以锁紧立柱214和弹性件6，实现支架组件2和弹性件6的固定连接，而且，为了避免第三螺钉80挤压损伤弹性件6，可以在第三螺钉80的螺帽和弹性件6之间设置第三垫片801。
请参阅图13，振动马达还包括设置在弹性件6远离立柱214的一侧的第二焊点90，立柱214和弹性件6通过在第二焊点90处焊接的方式固定连接，具体为在立柱214和弹性件6相接触之后，在弹性件6的第二焊点90处进行焊接以将立柱214和弹性件6固定在一起，实现支架组件2和弹性件6的固定连接。
请参阅图1，在一个实施例中，壳体1包括具有通腔的外壳12和盖合装配于外壳12的两端以形成收容空间11的两盖板13，弹性件6与外壳12之间通过烫点的方式固定，且弹性件6的两端分别抵接于外壳12和盖板13。具体的，弹性件6可以由在弹性片上开设若干通槽形成，弹性件6的边缘固定在外壳12，支架组件2固定连接于弹性件6的中部区域，以使弹性件6可以提供振子组件复原的回复力和保证振子组件能够相对壳体1上下振动；弹性件6的边缘开设若干通孔，外壳12的端部设有若干凸起，外壳12的凸起伸入弹性件6的通孔内，以实现弹性件6与外壳12之间的烫点固定。应当理解，由于弹性件6的两侧分别抵接于外壳12和盖板13，在弹性件6与外壳12通过烫点固定的方式进行初步固定后，还可以通过盖板13将弹性件6压紧在外壳12上。
请参阅图1至图14，在一个实施例中，胶层22朝壳体1的内壁延伸形成接触部222，振动马达还包括一端固定于壳体1的侧壁且另一端固定于接触部222的柔性电路板8，柔性电路板8电连接于线圈7。具体的，包覆在支撑部212外侧的胶层22朝壳体1的内壁延伸形成接触部222，接触部222与壳体1的内壁之间具有间隙；柔性电路板8固定于接触部222靠近线圈7的一侧，便于线圈7与柔性电路板8连接。应当理解，由于将柔性电路板8固定在胶层22，且柔性电路板8具有柔性，使得柔性电路板8与胶层22的连接端可以跟随支架组件2振动，以避免线圈7与电路板之间的连接因发生相对移动而断裂。振子组件还包括套设固定于胶层22外侧且间隔线圈7设置的两质量块3，质量块3与壳体1的内壁之间具有间隙。具体的，质量块3设置在支撑部212远离线圈7的一侧，以使质量块3被支撑部212支撑固定；质量块3可以跟随支架组件2振动以提供振动量，从而提升振子组件的振动效果。定子组件包括固定于壳体1的极芯4和固定于极芯4靠近支架组件2的一侧的磁钢5，磁钢5位于两质量块3之间，磁钢5用于提供磁场。具体的，壳体1内设有两定子组件，两定子组件设置在线圈7的两侧，且两定子组件相对设置，即两块磁钢5设置在线圈7的两侧且相对设置，以保证磁钢5可以提供线圈7切割的磁场。应当理解，振子组件设置在壳体1的中部区域，定子组件分布在振子组件的两侧，使得振动马达的零件排布紧密，空间利用率较高。
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。
