The "catalyst" ring motor(ring motor) for mobile phone photo function. Since 1986, China has introduced nine-year compulsory education. Under the influence of this policy, the educational level of the broad masses of the people has been continuously raised and the number of illiterate people has been gradually reduced. Comrades who have received nine-year compulsory education should all know the existence of catalysts. Catalysts are substances that change the reaction rate but do not change the general standard of the reaction. Catalysts play a catalytic role in chemical reactions and accelerate chemical reactions so that the reaction can be achieved as soon as possible. Chemical balance. The ring motor(ring motor) is similar to the presence of a catalyst in the mobile phone's photo function.
So where does the loop motor act as a catalyst in the camera function of the phone? Answer: autofocus. Automatic loop Motors(coil motors) in the Jiaomada market are well suited to the needs of the mobile phone market due to their simple structure and small size, and are currently the mainstream technology used by smart phone cameras. With the continuous improvement of the performance of the coil motor, it gradually occupies a larger market share.
The automatic focus function of the mobile phone is achieved by locking the camera into the ring motor(ring motor), the ring motor(ring motor) abbreviation(VCM), its main cable ring, magnet group and shrapnel composition, The coil is fixed in the magnet group by the upper and lower shrapnel. When the coil is energized, the coil generates a magnetic field. The coil magnetic field interacts with the magnet group. The coil moves upwards, and the camera locked in the coil moves together. When the power is off, The coil returns under the elastic force of the shrapnel so that the autofocus function is achieved.
