Abstract
A speaker device according to an embodiment includes a panel, a plurality of vibration elements, and a driving unit. The plurality of vibration elements vibrate the panel. The driving unit applies, to a first vibration element, a first driving signal that includes a modulated wave provided in such a manner that a carrier wave in an ultrasonic wave band is modulated by a sound signal in an audible wave band and applies, to a second vibration element, a second driving signal that includes the carrier wave and is different from the first driving signal, so that a vibrational region is formed on the panel.
