Vibration stimulation device

A vibration stimulation device comprising:

• a box having a cavity;
• vibrators disposed in the cavity;
• light emitting elements disposed between the vibrators or disposed on the vibrators;
• an upper vibration layer configured to connect the vibrators and the light emitting elements to edges of the box on the cavity;
• bumps disposed on the vibrators;
• and
• thermoelectric elements disposed on the vibrators and disposed in the bumps,
• wherein each of the bumps surrounds a side of a corresponding one of the thermoelectric elements, and
• wherein each of the thermoelectric elements comprises:
• a lower substrate disposed on a corresponding one of the vibrators;
• lower electrodes disposed on the lower substrate;
• first type semiconductors disposed on the lower electrodes;
• second type semiconductors disposed on the lower electrodes adjacent to the first type semiconductors, the second type semiconductors connected in series to the first type semiconductors through the lower electrodes;
• upper electrodes disposed on the first and second type semiconductors, the upper electrodes connecting the first type semiconductors to the second type semiconductors in series;
• and
• an upper substrate disposed on the upper electrodes
• wherein the upper substrate is exposed at a central portion of each of the bumps.
