Abstract
In an embodiments, an electronic device 1 has a panel 20 of roughly rectangular shape, a housing 10 that holds the panel 20, and a piezoelectric element 30 installed on the rear face side of the panel 20, wherein the panel 20 is bonded to the housing 10 with its edges supported on the housing 10, and it also has at least one side 21 not bonded to the housing 10 (non-bonded side). The electronic device is capable of causing an entire panel to vibrate in a stable manner.
Claims9
An electronic device having a panel of roughly rectangular shape having a pair of long sides and a pair of short sides, a housing that holds the panel, and a piezoelectric element installed on a rear face side of the panel, wherein the panel is bonded to the housing with its edges supported on the housing, wherein:
- at least one of the pair of short sides is not bonded to the housing in its entirety (non-bonded side), and
- the pair of long sides are bonded to the housing (bonded side) along their edges wherein each bonded side has, along its edge, at least one non-bonded region which is not bonded to the housing, wherein the at least one non-bonded region is formed at a center of the bonded side in a longitudinal direction in a manner displacing a peak of vibration amplitude of the panel toward a center of the panel from an installed position of the piezoelectric element in the longitudinal direction when the piezoelectric element is driven.
