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.
