Abstract:
A magnetic interference-resistant translation-type optical image stabilization voice coil motor includes a base, a spring plate, a lens carrier, at least three groups of magnets, and a housing. The base, the housing, and the groups of magnets are connected together to form a fixed structure. The groups of magnets are disposed inside the housing. Each group of magnets includes a first magnet and a second magnet stacked on the first magnet. The first magnet and the second magnet have opposite magnetic field directions. The lens carrier includes a body and coils disposed on the body. The number of the coils is the same as the number of the groups of magnets. Each of the coils is disposed opposite to one of the groups of magnets. The spring plate is connected to the lens carrier and one of the first magnet and the second magnet.
