Claims48
An apparatus, comprising:
- a display panel configured to display an image;
- a vibration apparatus disposed at a rear surface of the display panel to vibrate the display panel, the vibration apparatus including a plurality of vibration structures, and at least one of the plurality of vibration structures including a plurality of layers stacked on each other;
- and
- a pad member disposed outside or inside the vibration apparatus, the pad member having a different shape from the plurality of vibration structures in a plan view and including a plurality of layers stacked on each other,
- wherein each of the plurality of layers of the pad member comprises a same material as a material comprised in a respective one of the plurality of layers of the at least one of the plurality of vibration structures,
- wherein the pad member is spaced apart from the plurality of vibration structures, overlaps a region between the plurality of vibration structures, and has a same shape as the region between the plurality of vibration structures,
- wherein the pad member has a smaller size than the vibration apparatus, and
- wherein the pad member is a resonance control pad configured to adjust a resonance of the vibration apparatus and to prevent a resonance frequency in the region between the plurality of vibration structures.
