摘要： Provided is an electronic device 1, including: a piezoelectric element 30; a panel 10 configured to support the piezoelectric element 30; and a housing 60 configured to hold the panel 10 and conduct a vibration through the panel 10, the panel 10 generating air-conduction sound and vibration sound that is transmitted by vibrating a part of a human body. The housing 60 includes a first housing portion 62 and a second housing portion 61 located inward of the first housing portion 62, and rigidity-reinforcing portions (63, 150; 64, 160; 65, 66, 170) are disposed between the first housing portion 62 and the second housing portion 61 for improving rigidity of the housing 60.

摘要： Provided is an electronic device including a housing and an acoustic device configured to generate vibration sound that is transmitted through vibration of a part of a human body. The acoustic device includes a panel configured to be joined to the housing; a piezoelectric element configured to be joined to the panel for vibrating the panel; and a vibration adjusting unit configured to be joined to the panel and vibrated together with the panel by the piezoelectric element. With the above configuration, a frequency characteristic is improved.

摘要： Provided is an electronic device that can be appropriately used as a type of electronic device that vibrates a panel attached to a housing. The electronic device includes a piezoelectric element, a panel, to which the piezoelectric element is attached, that vibrates due to the piezoelectric element to generate a vibration sound transmitted by vibrating a part of a human body, a housing supporting the panel with a first face, a microphone contained within the housing and disposed on a second face, and a buffer that damps vibration transmitted from the panel to the microphone through the first face and/or the second face, thereby reducing noise picked up by the microphone.
