1. A vibration generating device comprising:
a housing;
a diaphragm supported by the housing, and configured to generate sound by vibrating in a first direction; and
a vibration providing part attached to the housing, and configured to vibrate the housing,
wherein the vibration providing part vibrates the housing in the first direction at a first frequency, and vibrates the housing in a second direction at a second frequency lower than the first frequency,
wherein the vibration providing part includes
an inside housing,
a vibrator contained in the inside housing,
an elastic supporter configured to support the vibrator to be capable of vibrating along the first direction and along the second direction, and
a magnetic drive part configured to drive the vibrator along the first direction and along the second direction by using magnetic forces,
wherein the magnetic drive part includes
a first magnetic field generating part arranged on a vibrator side, and
a second magnetic field generating part arranged on an inside housing side, as to be positioned on an extended line of the vibrator in a third direction orthogonal to the first direction and to the second direction,
wherein the elastic supporter is formed with a plate spring that includes
a plurality of folded parts each having a fold folded along the third direction, and
a flat part extending from one of the folded parts to another of the folded parts.
