Abstract
According to an aspect, an electronic device includes: a piezoelectric element; a sound generating unit that is vibrated by the piezoelectric element and generates a vibration sound to be transmitted while vibrating part of a human body; and a detection unit that detects contact of the part of the human body with the sound generating unit. A volume of the vibration sound is changed corresponding to a detection result of the detection unit.
