Abstract: A vibration generating device includes a movable body in a housing, supported to vibrate along a first direction; a bracket attached to the housing, including a body plate extending in a second direction and a first reinforcing plate extending in a third direction from one end of the body plate in the second direction; a coil attached to the body plate, including main-bundle-wire-parts in the second direction connected by a sub-bundle-wire-part; and a magnet attached to the movable body on another side of the coil in the third direction, generating a magnetic flux toward the main-bundle-wire-part. One end of the magnet in the second direction is inside one end of the sub-bundle-wire-part in the second direction. The first reinforcing plate extends from inside one end of the sub-bundle-wire-part in the second direction and outside one end of the magnet in the second direction, toward another side in the third direction.

Abstract: A vibration generating device includes a stationary body including a bottom surface, a movable body disposed in an upper space of the bottom surface, and an elastic support disposed between the stationary and movable bodies and configured to support the movable body to be vibratable forward and backward to the stationary body. The elastic support includes a fixed portion fixed to the bottom surface, an upright portion extending upward from the fixed portion, an elastically deformable portion extending from the upright portion leftward and rightward, and a movable-body-attaching portion that extends from the elastically deformable portion and to which the movable body is attached. The elastic support includes a projection extending from the upright portion leftward and rightward at a position different from a position at which the elastically deformable portion extends from the upright portion leftward and rightward. A buffer is included between the projection and the stationary body.
