Information processing apparatus and electronic device

An information processing device comprising:

• a memory;
• a processor coupled to the memory and configured to:
• drive a first vibrating element of a vibrating element of an electronic device, which includes a top panel that has an operation surface, a position detection circuit that detects a position of an operational input performed on the operation surface, the first vibrating element that generates vibration on the operation surface, and a second vibrating element that generates vibration on the operation surface, with a first drive signal that generates a first natural vibration in an ultrasonic band on the operation surface when the operational input is performed on the operation surface;
• and
• drive the second vibrating element with a second drive signal that generates vibration in a frequency band perceivable by a human sensory organ on the operation surface when the first vibrating element is driven for a predetermined time.
