Abstract: A lens driving device includes a fixed member including a base member; a lens holder including a cylindrical portion configured to hold a lens body; and a plurality of shape memory alloy wires configured to move the lens holder with respect to the fixed member. The fixed member includes a fixed contact that forms a stopper configured to restrict movement of the lens holder. The lens holder includes an elastic portion formed of a material that is softer than that of a synthetic resin material forming the cylindrical portion of the lens holder. The elastic portion includes a movable contact that faces the fixed contact of the stopper so as to be able to contact the fixed contact of the stopper.

Abstract: A vibration generator includes a housing, a first vibrator, and a second vibrator. The first vibrator includes a hollow yoke having a through hole, a magnet disposed within the through hole of the yoke, and a first elastic support member. The second vibrator includes a coil disposed above or below the magnet within the through hole of the yoke, and a second elastic support member to which the coil is fixed and that is disposed to extend from the inside to the outside of the through hole of the yoke and that is fixed to the housing. The first vibrator vibrates at a first natural frequency in a direction connecting both side portions of the yoke. The second vibrator vibrates at a second natural frequency that is different from the first natural frequency, in the direction connecting the both side portions of the yoke.

Abstract: A vibration generating device includes a housing, a vibrator including a magnet, and a resilient member between the housing and the vibrator. The vibration generating device includes a coil configured to generate a magnetic field that causes the vibrator to vibrate. The vibration generating device includes a bracket including a coil-mounting portion on which the coil is mounted. The housing includes bracket supports provided at ends of two opposing side surfaces among the four side surfaces of the housing, the ends being situated opposite ends, of the two opposing side surfaces, to which the bottom of the housing is connected. The bracket includes connection portions bonded to the respective bracket supports. The bracket supports of the housing and the connection portions of the bracket are connected together in a state in which the bracket is inserted into a space of the housing.
