Abstract
A vibration generating device includes: a stationary body; a movable body housed in the stationary body; a guide member configured to guide the movable body so that the movable body is reciprocally movable in the stationary body along a left-and-right direction; a magnetic flux-generating member fixed to the movable body and configured to generate a magnetic flux along an up-and-down direction; a coil fixed to the stationary body to cross the magnetic flux and includes electrically conductive wires extending along a front-and-back direction and being juxtaposed along the left-and-right direction; and a magnetic member fixed to the stationary body and disposed at an outer side of the coil. The magnetic member is disposed to generate an attractive force to attract the movable body located at a position off a center of a movable range of the movable body, to the center of the movable range of the movable body.
