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:
| |
old products |
new product |
utility |
| material quality |
voice coil type electromagnetic drive motor |
the piezoelectric material drives the motor with a stroke of 1200μm |
the moving range of the old product is limited, and the stroke is usually less than 350 m. the new product can travel 1200μm |
| structure |
shrapnel suspension moving lens |
the piezoelectric material pushes the drive rod and drives the lens to move |
when the lens moves, the optical axis of the lens is stable, and the optical axis variation is small. |
| design |
electromagnetic drive force and suspension wire suspension force design |
design of corresponding structure for piezoelectric material drive |
no magnetic interference, large thrust, can promote large-scale lens, improve the quality of photography, and provide long travel to support high optical rate lens focus |
| technology |

the trip is usually less than 350μm. |
itinerary 1200μm.the optical axis of the lens tilt variation 0.14 |
driving 150mm optical lens, providing 5 times optical zoom function |
| use function |
general camera autofocus |
high optical rate lens long stroke focusing |
provides high optical zoom ratio |
