An electronic device is provided with a housing, a piezoelectric element, and a panel, which is attached to the housing and has a contact area contacting a part of human body, configured to vibrate by the piezoelectric element to generate a vibration sound to be transmitted by vibrating the part of human body, such that pressure from inside of the housing at the contact area of the panel is smaller than pressure from inside of the housing at different area from the contact area. Thereby the sound pressure property is improved, and thus the electronic device preferably transmits air conduction sound and vibration sound.
