Abstract
An apparatus comprises a display panel configured to display an image, a vibration apparatus disposed at a rear surface of the display panel and configured to vibrate the display panel, a supporting member disposed at the rear surface of the display panel and including a first member and a second member, and the first member and the second member are disposed on a same surface as the supporting member.
Claims38
An apparatus, comprising:
- a display panel displaying an image;
- a vibration apparatus disposed at a rear surface of the display panel and configured to vibrate the display panel;
- and
- a supporting member separated from the vibration apparatus by an air gap and including a first member and a second member,
- wherein the first member and the second member are disposed on a rear planar surface of the supporting member and the second member is disposed at least on two lateral sides of the first member to dampen vibrations of the first member,
- wherein the first member and the second member are disposed to be co-planar on the rear planar surface of the supporting member, and
- wherein the vibration apparatus is disposed between the display panel and the first member, and the vibration apparatus is disposed between the display panel and the second member.

An apparatus, comprising:
- a vibration member;
- a vibration apparatus interfacing with the vibration member and configured to generate a sound in a forward direction of the vibration member;
- and
- a supporting member separated from a rear surface of the vibration apparatus by an air gap,
- wherein the supporting member comprises a first member overlapping with the vibration apparatus and configured to generate a sound in a reverse direction opposite to the forward direction and a second member is disposed on at least on two lateral sides of the first member to dampen vibrations of the first member,
- wherein the first member and the second member are disposed to be co-planar on the rear planar surface of the supporting member, and
- wherein the vibration apparatus is disposed between the display panel and the first member, and the vibration apparatus is disposed between the display panel and the second member.

An apparatus, comprising:
- a display panel displaying an image;
- a vibration apparatus including a piezoelectric portion and a ductile portion, and configured to generate a first vibration from a front surface of the apparatus;
- a first member disposed on and planar with a rear surface of the vibration apparatus and separated from a rear surface of the display panel by an air gap and configured to generate a second vibration;
- and
- a second member that borders the first member on the rear surface of the vibration apparatus to dampen the second vibration of the first member,
- wherein the first member and the second member are disposed to be co-planar on the rear planar surface of the supporting member, and
- wherein the vibration apparatus is disposed between the display panel and the first member, and the vibration apparatus is disposed between the display panel and the second member.
