Abstract: 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.

Abstract: 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.

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.
