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 |
metal case |
non-metal case |
to reduce the interference caused by the motor magnet coil to the antenna signal |
| structure |
to achieve case impact strength by metal material |
to achieve case impact strength by structure upgrading |
having passed through mechanical reliability tests such as drop, roller, mechanical impact and short distance drop |
| design |
the motor magnet coils being evenly arranged on the four sides and four corners of the motor. |
1/3 area of the motor being free of magnet coil for the special design of the motor magnet coil |
to reduce the interference caused by the motor magnet coil to the antenna signal |
| technology |
single-sided unipolar magnetic polarization |
single-sided multipolar magnetic polarization |
to narrow coil-covered area to reduce the interference caused by the motor magnet coil to the antenna signal |
| performance |
ordinary linearity: 10um～15um |
10um～15um: ≤5μm |
fast and precise focus |
| use function |
easily interfered antenna signals due to closely arrangement |
reduced antenna signal interference for upgraded antenna arrangement |
contributing to narrow the top border of the phone, maintain communication quality and clear front camera focus |
