Abstract: A sound apparatus includes a first vibration member, a first vibration device having a rectangular shape including a first main surface and a second main surface opposite to each other and configured to vibrate based on a driving signal input thereto, the first main surface being connected to the first vibration member, a second vibration member having a rectangular shape including a first main surface and a second main surface opposite to each other, a portion of the first main surface being connected to the first vibration member and a portion of the second main surface of the first vibration device by an elastic member, and a second vibration device having a rectangular shape including a first main surface and a second main surface opposite to each other and configured to vibrate based on a driving signal input thereto, the first main surface being connected to the second main surface of the second vibration member. The first vibration device may be disposed in a direction in which rotation has been performed by a certain angular degree with respect to an axis perpendicular to the first main surface of the second vibration device and the second main surface of the second vibration device.

Abstract: A sound apparatus includes a vibration member having a plate shape; and a first vibration device, a plurality of second vibration devices, and a third vibration device configured to each have a plate shape including a first main surface and a second main surface opposite to each other and configured to vibrate based on a driving signal input thereto. The first main surface of the first vibration device may be connected to the vibration member, a portion of the second main surface of the first vibration device and a portion of the first main surface of the third vibration device may be connected to each other by an elastic member so that the first main surface of the third vibration device is spaced apart from and opposite to the second main surface of the first vibration device by a certain distance. A portion of each of the plurality of second vibration devices may be connected to a portion of the third vibration device and a portion of the first main surface of each of the plurality of second vibration devices may be connected to a portion of the vibration member by an elastic member, so that the plurality of second vibration devices extend radially from the third vibration device in a plane. A driving signal input to the first vibration device may have a phase opposite to a phase of a driving signal input to the third vibration device.
