 本发明的实施方式
下面结合附图和实施方式对本发明作进一步说明。
请参阅图1和图2，为本发明实施例提供的一种振动马达，包括：壳体1、振动件2、固定件3和弹性支撑件4。壳体1具有收容空间10，振动件2、固定件3和弹性支撑件4均收容于收容空间10内，弹性支撑件4将振动件2悬置支撑于收容空间10中。请参阅图4，弹性支撑件4包括：第一固定部41、第二固定部42以及弹力臂43，第一固定部41固定于壳体1，第二固定部42固定于壳体1并与第一固定部41间隔设置，弹力臂43连接在第一固定部41与第二固定部42之间。弹力臂43包括：第一连接臂431、第二连接臂432以及延伸臂433，第一连接臂431与第一固定部41连接，第二连接臂432与第二固定部42连接，延伸臂433连接在第一连接臂431与第二连接臂432之间，并与振动件2连接固定，弹力臂43悬置于收容空间10内并提供振动件2的回复力。
该弹性支撑件通过第一固定部和第二固定部与壳体固定，通过延伸臂与振动件固定，在振动时能够稳定的将振动件悬置支撑于收容空间，不易脱落，不需要额外在弹性支撑件与振动件之间加阻尼片，以及在壳体的底部设置跌落保护片，减少了振动马达所需的元件，提高了振动马达的生产效率，节约了生产成本。
请参阅图3和图4，第一固定部41与第二固定部42固定于壳体1的不同侧。弹力臂43还包括自延伸臂433朝振动件2方向延伸的凸块434，延伸臂433经由凸块434实现与振动件2的固定。振动件2对应延伸臂433设有连接块211，连接块211与凸块434一体成型，使振动件2与弹性支撑件4的连接更加稳固。弹性支撑件4由高分子材料制成，该高分子材料可以是高分子硅胶材料或者高分子橡胶材料。由于该高分子材料不是金属材料，即使发生跌落也不会与外壳碰撞产生噪音，甚至损坏外壳，因此能给客户带来更好的使用体验。
请参阅图2和图3，壳体1包括：底壁11、顶壁12以及侧壁13，底壁11用于固定固定件3，顶壁12与底壁11相对且间隔设置，侧壁13自顶壁12弯折延伸至底壁11。侧壁13包括：设置在振动件2沿振动方向的相对两端的第一侧壁131以及连接第一侧壁131的第二侧壁132。第一固定部41与第二固定部42相互正对设置且分别固定在第二侧壁132。第一连接臂431沿振动方向的厚度朝远离第一固定部41的方向逐渐减小，第二连接臂432与第一连接臂431对称设置在延伸臂433的两侧。第一固定部41及第二固定部42远离振动件2的一侧与第一侧壁131抵接，使振动传导的效果更加明显。于本发明另一实施例中，第一固定部41固定在顶壁12，第二固定部42固定在底壁11。
仍请参阅图2和图3，振动件2包括：配重块21和磁体22，配重块21对应延伸臂433的位置设有连接块211，连接块211与凸块434一体成型，使振动件2与弹性支撑件4的连接更加稳固。配重块21中设有容置腔212，磁体22收容于容置腔212中且由配重块21承托。固定件3包括：电路板31和线圈32，电路板31安装在底壁11上，线圈32与电路板31电连接。磁体22与线圈32正对且间隔设置。
具体地，磁体22包括第一子磁体221、两个分别设置在第一子磁体221两侧的第二子磁体222以及分别设置在两个第二子磁体222外侧的第三子磁体223，五个磁体依次相接组装，五个磁体与通电后的线圈32相互作用，从而使得振动件3整体产生振动效果。可以采用磁性相同的5个子磁体，也可采用磁性不同的5个子磁体。当5个子磁体磁性不同时，根据通电后线圈32所产生的磁通分布情况对五个磁体的磁性强弱进行合理排布，如此，当线圈32通电后，五个磁体能够较好地与线圈32产生的磁通配合而达到更加平衡的振动效果。于本发明又一实施例中，振动件2包括：配重块和线圈，固定件3包括：电路板和磁体。
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
