Abstract
A voice coil motor includes a base, a lens housing, a voice coil, a magnet, a first elastic sheet, and a yoke member. The lens housing has a first margin wall, and a first protrusion and a second protrusion extend from the first margin wall. The height of the second protrusion is lower than the height of the first protrusion. The yoke member has a first wall, a connection wall, a second wall, and a side wall. The first wall, the connection wall, and the second wall together form a stepped structure. The first wall is disposed on the first protrusion, and the second wall is disposed on the second protrusion. The lens housing has a deflectable angle relative to a horizontal reference line. When the lens housing deflects to a maximum value of the deflectable angle, the second protrusion abuts against the second wall.
