compared with the old products, what are the improvements（structure, material, technology, process, performance and use function）
with the increasing mobile phone camera pixel camera, auto focus motor dynamic axis tilt angle requirements increasingly strict, consider upgrading the camera autofocus motor can meet the high pixel application, the new products of high pixel camera autofocus motor has the following improvement:

hall sensor helps to focus more procisely by feeding back the position and forming a close loop |
small posture difference, be able to focus if it is matched with such controlling software as pdaf and be applied in dual camera |
| design |

in addition to the fixed magnet and the movable coil, it is also necessary to move the magnet and the hall for design simulation analysis, design and analysis of resonance suppression is also needed. |
closed loop control can be performed without vibration problems |
| technology |

use damping glue to control resonance frequnce |
reduce frequency resonance |
| performance |
/ |
posture difference≤8um |
provide easy control and adjustment for ccm |
| use function |
