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.

Device comprising a panel and piezoelectric element

A portable terminal device includes a first body having an operation section on a main surface thereof, a second body having a display section on a main surface thereof, a connection device for connecting the first body and the second body so that the portable terminal device is openable and closable, a memory storage section having an opening section openable to another main surface of the second body, a lid for opening and closing the opening section and retaining a removable memory in the memory storage section, wherein the operation section is covered by the second body when the portable terminal device is in a closed state, and is exposed to the outside when the portable terminal device is in an open state, and the display section is exposed to the outside in either the closed or opened state.
