当两片X方向弹片4用于连接对焦马达组件3和光学防抖框2时所述两片Y 方向弹片5用于连接底座1与光学防抖框2；并且在X轴驱动下使得对焦马达组件3在垂直于光轴a1的水平面内沿X轴单向平移；或者在Y轴驱动下使得对焦马达组件3在垂直于光轴a1的水平面内沿Y轴单向平移。
即，X轴单向平移和Y轴单向平移是择一方向单向平移，即，通过光学防抖框架悬挂的X-Y弹片，得到更优于其它光学防抖机构的单向性能，且能极大简化生产工艺，降低成本。
其次，实现光学部件(例如透镜)垂直光轴的平移运动，光学部件配置在对焦马达组件上，X轴驱动机构6和Y轴驱动机构7驱动对焦马达组件实现垂直光轴的平移运动，达到光学部件平移运动的光学防抖目的。
通过光学防抖框，分别悬挂X方向弹片和Y方向弹片，当对焦马达组件在X向运动时，仅X方向弹片作用相反力，Y方向弹片零作用，保证了X向实现高精度运动；同理，Y向也能实现高精度运动。如此实现的对焦马达组件在X-Y复合的高精度运动。
相邻的X方向弹片4和Y方向弹片5呈垂直分布。
具体地，如图1-3所示，本实施例的X方向弹片4结构和Y方向弹片5的结构相同，均包括中间固定部40和两个端部固定部41，以及两个腕部42，在中间固定部40的两端分别连接有一腕部42，在每个腕部42远离中间固定部40的一端连接有一端部固定部41。

利用中部和两端的固定连接，同时协同腕部的构造，其可以确保光学部件在X方向或Y轴单向平移的稳定性，以X轴单向平移为例：当X方向的两片X方向弹片其腕部受到X轴驱动力时，由于是相对分布，此时其可以确保承载光学部件的对焦马达组件3在垂直于光轴的X轴单向平移。
具体地，如图1所示，在底座1的四个角部分别设有第一弹片固定部10，两个第一弹片固定部10为一组。每片Y方向弹片5的两个端部固定部41分别固定在同一组的两个第一弹片固定部10上。

具体地，如图4-6所示，X轴驱动机构6包括固定在底座1上的两个X轴驱动线圈60，在对焦马达组件3的外框30下端其中两个相对侧分别设有与所述的X轴驱动线圈60一一相对的X轴驱动磁石61。本实施例的X轴驱动磁石61为双块磁石，即，两块磁石处于同一个与光轴垂直的水平面上，以提高磁力驱动 力。
X轴驱动磁石61位于X轴驱动线圈60上方。
Y轴驱动机构7包括固定在底座1上的两个Y轴驱动线圈70，在对焦马达组件3的外框30下端另外两个相对侧分别设有与所述的Y轴驱动线圈70一一相对的Y轴驱动磁石71。本实施例的Y轴驱动磁石71为双块磁石，即，两块磁石处于同一个与光轴垂直的水平面上，以提高磁力驱动力。
Y轴驱动磁石71位于Y轴驱动线圈70上方。
优选地，上述的X轴驱动磁石61和Y轴驱动磁石71处于同一个与光轴垂直的水平面上，这种结构其便于加工设计组装，以及确保重心平衡。
优选方案，如图4所示，在外框30内壁的四壁面上分别设有磁石定位槽300，双块磁石其中内侧的一块X轴驱动磁石61伸入相应的磁石定位槽300，以及双块磁石其中内侧的一块Y轴驱动磁石71伸入相应的磁石定位槽300，在外框30外壁的四外壁面上的每一外壁面两端分别设有外凸部301，同一外壁面上的两根外凸部301之间形成磁石固定空间，所述双块磁石另外一块X轴驱动磁石61固定在相应的磁石固定空间中，以及设置在外框30下端四端面上并且与所述磁石固定空间连通的定位槽体302，所述双块磁石另外一块Y轴驱动磁石71固定在相应的定位槽体和磁石固定空间中，并且双块磁石的两块Y轴驱动磁石71其下表面齐平。
其次，如图8-9所示，为了能够进一步减薄装置沿着光轴方向上的厚度，本实施例的光学防抖框2套在对焦马达组件3的外框30上端外侧，并且光学防抖框2和外框30之间留有间隙。避免了光学防抖框2位于外框30上方而增大厚度尺寸，即，本实施例的这种结构其可以被应用于更小的安装空间。
另外，在底座1上连接有外壳8，所述的对焦马达组件3、光学防抖框2和光学防抖弹性支撑机构内置于底座1与外壳8形成的腔室中。在外框30的四个角部分别设有避让缺口303，以供与避让槽相对的内凸起避让，避免干涉。
