摘要 |
Provided is an electronic device that is capable of reducing sound leakage from a vibration plate vibrated by a piezoelectric element. An electronic device 1 of the present invention includes: a piezoelectric element 30; and a vibration plate 10 configured to be vibrated by the piezoelectric element 30. Vibration sound is transmitted by the vibration plate vibrating a part of a human body. The piezoelectric element 30 is 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. |
