Abstract
A display device unit includes: a display device; and a sound element disposed at a side surface or a rear surface of the display device, where the sound element includes a vibration material layer which provides a sound based on an electric field applied therein, and a pair of electrodes which generates the electric field in the vibration material layer.
Claims8
A display device unit comprising:
- a display device;
- a sound element disposed at a side surface or a rear surface of the display device;
- a vibration plate disposed between the display device and the sound element;
- and
- a back chassis disposed at a rear surface of the display device, and comprising a fixing protrusion which protrudes toward the rear surface of the display device,
- wherein the sound element comprises:
- a vibration material layer which generates a sound based on an electric field applied therein, and
- a pair of electrodes which generate the electric field in the vibration material layer, and
- wherein the fixing protrusion is formed integrally with the back chassis and of the same material as that of the back chassis, and
- wherein the sound element is disposed between the fixing protrusion and the vibration plate and the fixing protrusion overlaps a center of the sound element and contacts one of the electrodes of the sound element such that the fixing protrusion effectively prevents the sound element from being displaced by vibration.
