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 |

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 |
