A speaker device according to an embodiment includes a vibration element, a driving unit, and a panel. The driving unit applies, to the vibration element, a driving signal where a carrier wave in an ultrasonic wave band is modulated by a sound signal in an audible wave band. The panel is provided with the vibration element and arranged in such a manner that a driving signal is applied to such a vibration element by the driving unit to form a vibration region and first and second ultrasonic waves that are generated from such a vibration region and travel in mutually different directions travel toward respectively different users.
