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.

Vibration generating device

An input device which is capable of imparting a magnetic operational reaction force, includes a stationary member, a magnetic member fixed to the stationary member, a movable member at least partially housed in the stationary member to which the magnetic member is fixed, and a driving device including a magnet fixed to the movable member and coils fixed to the stationary member, configured to move the movable member in a first direction relative to the stationary member, wherein the magnet is magnetized along a second direction perpendicular to the first direction, wherein the coils have bundles of turns constituted by conductive wires, and the conductive wires in the bundles of turns extend along a third direction perpendicular to each of the first direction and the second direction, and the conducting wires are juxtaposed along the first direction.

Input device

A vibration generating device includes a coil and a magnetic flux source. The magnetic flux source includes a left-hand magnet, a first middle magnet, a second middle magnet, and a right-hand magnet. The coil includes a left-hand coil and a right-hand coil. The left-hand coil and the right-hand coil each include a left-hand wire bundle and a right-hand wire bundle. Magnetic fluxes from the middle magnet passing through, in an up-and-down direction, a space between the right-hand wire bundle of the left-hand coil and the first middle magnet are less than magnetic fluxes from the left-hand magnet that pass through, in the up-and-down direction, a space between the left-hand wire bundle of the left-hand coil and the left-hand magnet.
