Abstract: A sound output apparatus outputs sound from a side of the apparatus on which a display is located. The sound output apparatus includes: a display element that includes the display; a driven element that is driven in accordance with a drive signal; a transmission panel that transmits vibrations of the driven element to the side of the apparatus on which the display of the display element is located; and a cover panel that is placed on an opposite side of the display element than the driven element. The transmission panel is placed between the display element and the driven element, and is joined at least to a portion of a periphery region of the cover panel. The cover panel has the periphery region that extends around an outer periphery of the cover panel as viewed from the side of the apparatus on which the display is located.

Abstract: An input apparatus includes an operation panel, a vibrator, and a holding part. The operation panel includes an operation surface. The vibrator is attached to the operation panel, and vibrates the operation panel in a plurality of modes having different vibration frequencies. The holding part holds the operation panel. The holding part includes a first holding part, and a second holding part that has a higher hardness than the first holding part, and is arranged to be laminated on the first holding part.

Abstract: There is provided a control device. An operation detector configured to detect a user's operation on an operation surface of a panel. A driving unit configured to vibrate the panel by driving a vibration element attached to the panel. Wherein when the operation is detected by the operation detector, the driving unit combines a sound signal of sound, which is to be generated from the panel by vibration of the panel, with a drive signal for generating, in the panel, haptic vibration to provide the user with vibration of a haptic sense, and outputs a combined signal to the vibration element, thereby generating the haptic vibration and the sound in the panel.

Abstract: An input device according to an embodiment includes an operation panel, a selection unit, a detector, a vibration element, a setting unit, and a vibration control unit. The selection unit selects a to-be-controlled object using the operation panel in accordance with the user's action. The detector detects touch operation on the operation panel. The vibration element vibrates the operation panel. The setting unit sets a vibration pattern of the vibration element appropriate to the touch operation detected by the detector, depending on the to-be-controlled object selected by the selection unit. The vibration control unit controls the vibration element to generate the vibration pattern set by the setting unit.
