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 |
/ |
the inducive magnets should be moved to have design and simulation analysis together with the driver. |
closed loop control is possible |
| technology |
/ |
use damping glue to control resonance frequnce |
reduce frequency resonance |
| performance |
/ |
dt≦8分，high precision |
provide easy control and adjustment for ccm |
| use function |
/ |
close loop provides higher precision and faster response |
be able to focus if it is matched with such controlling software as pdaf and be applied in dual camera |
