Nowadays, the image quality of mobile phone photography has become a marketing highlight of major mobile phone manufacturers, and the focus motor that can drive the movement of the mobile phone camera module lens has naturally become the core product of mobile phone manufacturers' competition.
BTJX Micro Motor Technology Co., Ltd. independently researches and develops a miniature closed-loop voice coil motor with rare earth neodymium iron boron permanent magnet materials. Through position feedback, the closed-loop system can control the shaking time and speed up the focusing speed, thereby improving the quality of photo shooting. The production of this miniature closed-loop voice coil motor has accelerated the transformation and upgrading speed of domestic substitution of imports. It has now passed the certification of Huawei, Samsung and other brands, and its technology has reached the international leading level.
