    • A lens actuation device for an optical system includes a housing, a carrier at least partially installed in the housing, and a plurality of transducers arranged around the carrier in the housing. All the transducers are coupled with the mount, and at least one transducer includes at least one magnet and at least one coil. At least one transducer includes at least one yoke. All the transducers when powered on may generate independent or consistent movement to cause the mount to make linear movement, rotation, or both relative to the housing. An optical system adopting the lens actuation device and a camera using the same are also presented. The device of the present invention uses the transducers to drive the carrier, such that the lens set is driven to make linear movement, rotation, or both, thereby achieving the flexible manipulation of the lens.
    • 用于光学系统的透镜致动装置包括壳体,至少部分地安装在壳体中的托架以及围绕壳体中的托架布置的多个换能器。 所有传感器与安装座相连,至少一个传感器包括至少一个磁体和至少一个线圈。 至少一个换能器包括至少一个轭。 所有传感器上电时可能会产生独立或一致的运动,使安装座相对于外壳进行线性运动,旋转或两者。 还提出了采用透镜致动装置的光学系统和使用其的照相机。 本发明的装置使用换能器驱动载体,使得透镜组被驱动以进行线性运动,旋转或两者,从而实现透镜的灵活操作。
