Provided is an electronic device that is capable of reducing sound leakage from a vibration plate vibrated by a piezoelectric element. An electronic deviceof the present invention includes: a piezoelectric element; and a vibration plateconfigured to be vibrated by the piezoelectric element. Vibration sound is transmitted by the vibration plate vibrating a part of a human body. The piezoelectric elementis vibrated using a processed sound signal in which at least a part of frequency components of a sound reproduction signal that are higher than a predetermined threshold value is cut or attenuated.
