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:

be composed of an ois and an close loop vcm |
ois |
| design |
/ |
using closed-loop hall to sense the focus position for precise focus; using sma energized deformation characteristics combined with the clamping mechanism to achieve ois |
closed loop improves focus accuracy and saves focus time significantly |
| technology |
/ |
add closed-loop induction components; assembly of sma components; assembly of vcm sma ois components |
separate assembly can improve assembly efficiency, and final assembly reduces assembly failure |
| performance |
