    • PROBLEM TO BE SOLVED: To provide a type of electronic apparatus that vibrates a panel thereby generating air conduction sounds and vibration sounds, and operates well.SOLUTION: An electronic apparatus is provided with: a housing; a piezoelectric element; and a panel attached to the housing and provided with a contact region contacting with a part of a human body, the panel which is vibrated by the piezoelectric element thereby generating air conduction sounds and vibration sounds transmitted by vibrating the part of the human body. A pressure from the interior of the housing in the contact region of the panel is set so as to be smaller than a pressure from the interior of the housing in another region different from the contact region to improve the sound pressure characteristics.
    • 要解决的问题:提供一种振动面板的电子设备,从而产生空气传导声和振动声,并且运转良好。电子设备设有:壳体; 压电元件; 以及安装在壳体上并具有与人体的一部分接触的接触区域的面板,该面板由压电元件振动,从而产生通过振动人体的部分而传递的空气传导声和振动声。 在面板的接触区域中,壳体内部的压力被设定为小于在与接触区域不同的另一区域中的壳体内部的压力,以提高声压特性。
