Abstract

The content of sound leakage from a vibrating plate that vibrates due to a piezoelectric element is made difficult to recognize. An electronic device (1) according to the present invention includes a piezoelectric element (30) and a vibrating plate (10) that vibrates due to the piezoelectric element (30), the electronic device (1) causing the vibrating plate (10) to generate air-conducted sound and vibration sound that is transmitted by vibrating a part of a human body. The electronic device (1) also includes an air-conducted sound reducing unit that makes a portion or all of the air-conducted sound difficult to hear.
