Tactile presentation device

A tactile presentation device comprising:

• a panel including a region touchable by a user;
• a plurality of vibrators disposed outside the touchable region on the panel;
• and
• a driving controller configured to supply driving signals to the plurality of vibrators,
• wherein at least a part of the entire outer end of the panel is an absorber end region,
• wherein each point closest to one of the plurality of vibrators on the entire outer end of the panel is included in the absorber end region,
• wherein the driving controller is configured to supply driving signals to the plurality of vibrators to generate a standing wave on the touchable region,
• wherein each of the driving signals is a synthetic wave of a carrier and a modulating wave at a frequency lower than a frequency of the carrier, and
• wherein the driving controller is configured to control location of a node of the standing wave in the touchable region with phase differences among carriers of the driving signals for the plurality of vibrators.
