The utility model relates to a modified VCM motor magnet is applied to a VCM motor, VCM motor magnet is constituteed with half one second by first half one, first half one do not is located the field axis both sides of VCM motor magnet with half part of second, and is close to the both ends of the coil movement track line of VCM motor respectively, first half one with the configuration asymmetry of half one second, half first magnetic line of force with half formation of second distributes asymmetricly. Adopt the utility model provides a modified VCM motor magnet can let distribution magnetic line of force distribution density and orientation of different positions on coil movement track line change, further makes the coil more even at the magnetic field intensity that different stroke positions received, has reduced the thrust difference of different strokes, reaches the purpose of improving stroke linearity degree.
