function:
Auto-Focus Actuator
pixels:
8M
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 shell Non-metallic shell Reduce the interference of metal enclosure to antenna signal
structure With metal material to achieve shell impact resistance, structural strength By strengthening the structure design, the strength of the shell structure is achieved Mechanical reliability tests such as dropping, rolling, mechanical impact, short fall, etc.
design The motor magnet coil is equally arranged inside the motor with four corners and four corners The motor magnet coil is specially designed so that the motor 1/3 region does not contain a magnet coil Reduce the interference of motor magnet coil to antenna signal
Technology Magnet, single sided monopole, magnetic polarization Magnet single side multipole magnetic polarization Reduce the coil configuration area and reduce the motor coil interference to the antenna signal
performance General linearity in 10um~15um Linearity:≤5μm Fast and accurate focus
Use function The proximity antenna configuration is prone to interference with antenna signals Proximity antenna configuration reduces interference to antenna signals Help to narrow the mobile phone frame, maintain good mobile communications quality, and with pre focus, clear video quality
