Official abstract text for this publication.
There is provided an output apparatus that includes one or more display panels, a support member, and an actuator section. The one or more display panels are capable of displaying an image. The support member includes a support portion for supporting the respective one or more display panels. The actuator section is disposed between the one or more display panels and the support portion and vibrates the respective one or more display panels. In this output apparatus, an image is output by the one or more display panels. Further, the actuator section is disposed between the display panels and the support portion of the support member, and the display panels are vibrated.
