Touch panel apparatus and touch panel control method

A touch panel apparatus provided on a display surface of a display part and having a touch panel receiving an operation, the touch panel apparatus comprising:

• a plurality of piezoelectric elements that vibrate the touch panel;
• a vibration control part that drives the plural piezoelectric elements based on a set parameter value of a first parameter, a set parameter value of a second parameter, and a set parameter value of a third parameter;
• a first parameter table that stores a plurality of the parameter values of the first parameter;
• a second parameter table that stores a plurality of the parameter values of the second parameter;
• a third parameter table that stores a plurality of the parameter values of the third parameter;
• a touch sense pattern table that stores a plurality of touch sense pattern values made up of a combination of the plurality of the parameter values of the first parameter, the plurality of the parameter values of the second parameter, and the plurality of the parameter values of the third parameter;
• and
• a setting part that sets the parameter value of the first parameter, the parameter value of the second parameter, and the parameter value of the third parameter based on the plurality of the touch sense pattern values stored in the touch sense pattern table.
