Patent ID: 8174495

Claim:
An electronic apparatus, comprising: A display section a contact detection section for detecting contact from a user; the contact detection section including a touch panel, a vibration output section for outputting an acoustic vibration that can be sensed by the user as a sound and a haptic vibration for stimulating the haptic sense of the user, wherein the vibration output section includes a stacked piezoelectric actuator having a central electrode covered with an insulator, wherein the central electrode is in-between a plurality of piezoelectric elements; a pattern generation section for generating an output vibration pattern including the acoustic vibration and the haptic vibration in response to the contact detection section detecting the contact from the user; and a drive section for driving the vibration output section in accordance with the output vibration pattern to make the vibration output section output the acoustic vibration and the haptic vibration, wherein the drive section includes an acoustic drive section and a haptic drive section integrated into a single circuit.
