Abstract
The present invention provides a device with a piezoelectric element disposed at a location other than near an edge of a panel. A device includes a panel and a piezoelectric element disposed in a predetermined region on a planar surface of the panel. The panel vibrates in response to vibration of the piezoelectric element so as to transmit sound to a human body contacting the panel. By the piezoelectric element being disposed in the predetermined region of the panel, the center of the piezoelectric element is located within a range of 40% to 60% of the distance from one edge to the other edge of the panel in a first direction and within a range of 40% to 60% of the distance from one edge to the other edge of the panel in a second direction perpendicular to the first direction.
