发明名称 電子機器
摘要 Provided is an electronic device including: a piezoelectric element; a vibration plate to which the piezoelectric element is joined for vibration; and a housing to which the vibration plate is joined. Vibration sound, which is transmitted by vibrating a part of a human body, is generated by the vibration plate. The vibration plate includes, in a plan view thereof, a first area including a joining portion with the piezoelectric element and a second area located further away from the joining portion than the first area is, and rigidity in a first area is lower than rigidity in the second area. With the above configuration, sound leakage or the like is reduced, and usability of the electronic device is improved.
