Description

一种线性振动马达 技术领域

现有的线性振动马达通常包括壳体、振动组件和定子组件，其中，振动组件通常由质量块、永磁体以及弹片组成，定子组件通常由FPCB、阻尼件、限位块以及线圈组成，阻尼件起到控制线性振动马达的振动幅度和振动响应速度的作用。具体地，壳体上有密闭的收容空间，振动组件和定子组件均位于上述收容空间中，线圈通电后永磁体在电磁推力的作用下带动弹片和质量块一起作往复有规律的振动，从而实现线性振动马达的振动功能。
现有的阻尼件通常为设于质量块上的磁液，由于磁液起到的阻尼作用受到磁液量和磁液分布状态的影响较大，而生产过程中难以有效控制流动性强的磁液，因此以磁液为阻尼件时的线性振动马达良品率低。而且线性振动马达在经过例如是碰撞试验或跌落试验等可靠性试验后，磁液易失效，严重影响影响线性振动马达的振动响应性能。

  3. 根据权利要求1或2所述的线性振动马达，其特征在于，所述质量块上设有与至少部分所述主体相配合的定位凹槽。
  4. 根据权利要求1至3任一项中所述的线性振动马达，其特征在于，所述弹性臂沿着远离所述质量块的方向延伸，且所述弹性臂远离所述质量块的表面与所述中间臂邻近所述质量块的表面相贴。
  5. 根据权利要求1至4任一项中所述的线性振动马达，其特征在于，所述阻尼件为两个，且两个所述阻尼件分别设于所述质量块的长度方向上的两端。
  6. 根据权利要求1至5任一项中所述的线性振动马达，其特征在于，所述壳体包括上壳和下壳，所述线圈固定在所述下壳上，所述第一连接臂与所述上壳固定连接。
  7. 根据权利要求6所述的线性振动马达，其特征在于，所述定子组件还包括与所述下壳固定连接的限位块，以限制所述振动组件的振动行程。
  8. 根据权利要求7所述的线性振动马达，其特征在于，所述中间臂与所述限位块相对应的表面为斜坡面，以避免所述弹片在振动过程中与所述限位块碰撞。
  9. 根据权利要求1至8任一项中所述的线性振动马达，其特征在于，所述振动组件还包括设于所述质量块嵌设有所述永磁体一侧的华司板，所 述华司板与所述壳体和/或所述质量块固定连接。
  10. 根据权利要求1至9任一项中所述的线性振动马达，其特征在于，所述阻尼件的材质为硅胶。
