close loop AF actuator CSO01 (spring-type)MP

function:
quick AF
pixels:
48M
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 / / /
structure / 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 / 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
Technology / use damping glue to control resonance frequnce reduce frequency resonance
performance / posture difference≤8um 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
