摘要： A voice coil motor includes a holder, a metal yoke, a carrier, a plurality of magnets, a coil and at least two spring plates. The magnets are disposed in the metal yoke. The coil is wound around the carrier and adjacent to the magnets. The spring plates are coupled to the carrier. The holder includes a first opening, a cylindrical sidewall and at least two radial protrusions. The cylindrical sidewall is disposed around the first opening. The radial protrusions protrude from the cylindrical sidewall. The metal yoke is coupled to the holder and includes a second opening and a plurality of inner walls. The carrier is movably disposed in the metal yoke and includes at least two radial enlarged portions and a plurality of notches. Each of the radial enlarged portions is disposed correspondingly to each of the radial protrusions.
