VCM autofocus motor is realized by locking the camera into the voice coil motor. voice coil motor (VCM) is mainly composed of a coil, a magnet group and a shrapnel. The coil is fixed in the magnet group by the upper and lower shrapnel. When the coil is energized, the coil will move upward, and the camera locked in the coil will move together. When the power is off, the coil will return under the elastic force of the shrapnel, thus realizing the automatic focusing function.
