Description
本发明涉及摄像镜头的技术领域，特别涉及一种连续变焦光学镜头驱动装置。The invention relates to the technical field of camera lenses, in particular to a continuous zoom optical lens driving device.
在诸如数字照相机、可互换镜头***和摄像机拍摄设备中，用户要求高分辨率、大光圈等。由于拍摄设备适于小型化，因此拍摄设备最近也已被应用于紧凑型信息终端，如移动电话。此外，消费者在拍摄设备方面的专业知识已经提高，并且紧凑且高变焦系数的镜头的发展已经根据这样的市场需求也加强。目前，手持式摄像装置—尤其是手机的摄像头的自动调焦基本全部使用音圈电机(Voice Coil Motor，VCM)来完成，虽然音圈电机具有技术成熟、成本低、噪音低等优点，但是随着摄像装置对摄像要求的增加，如实现多镜头组可大范围变焦的效果等，音圈电机在存在磁干扰、推力不足、位移量不足等方面的劣势越来越明显，为此急需开发出音圈技术以外驱动技术的驱动器来解决摄像头驱动遇到的以上问题。In photographing devices such as digital still cameras, interchangeable lens systems, and video cameras, users demand high resolution, large aperture, and the like. Since the photographing device is suitable for miniaturization, the photographing device has also recently been applied to a compact information terminal such as a mobile phone. In addition, consumers' expertise in photographing equipment has increased, and the development of lenses that are compact and have a high zoom factor has also been strengthened in accordance with such market demands. At present, the automatic focus of handheld camera devices—especially the camera of mobile phones is basically completed by voice coil motor (Voice Coil Motor, VCM). With the increase of camera requirements for camera devices, such as realizing the effect of multi-lens group zooming in a wide range, etc., the disadvantages of voice coil motors in terms of magnetic interference, insufficient thrust, and insufficient displacement are becoming more and more obvious. Therefore, it is urgent to develop Drivers with driver technologies other than voice coil technology can solve the above problems encountered by camera drivers.
