Abstract
An apparatus can include a display member configured to display an image and a vibration apparatus disposed at a rear surface of the display member. Also, the vibration apparatus is configured to vibrate the display member using a driving signal based on a driving mode, and vibrate the display member using a vibration signal based on a vibration mode.
Claims19
An apparatus, comprising:
- a display member configured to display an image;
- a vibration apparatus disposed at a rear surface of the display member;
- and
- a driving circuit part connected to the vibration apparatus,
- wherein the vibration apparatus is configured to:
- vibrate the display member using a driving signal based on a driving mode,
- vibrate the display member using a vibration signal based on a vibration mode,
- wherein the driving signal includes a sound signal,
- wherein the vibration signal has a single frequency,
- wherein the driving circuit part is configured to:
- supply the driving signal based on the driving mode to the vibration apparatus;
- and
- supply the vibration signal based on the vibration mode to the vibration apparatus,
- wherein the vibration mode includes a first vibration mode and a second vibration mode,
- wherein the driving circuit part is further configured to:
- generate a first vibration signal based on the first vibration mode and supply the first vibration signal to the vibration apparatus;
- and
- generate a second vibration signal based on the second vibration mode and supply the second vibration signal to the vibration apparatus,
- wherein the first vibration signal is different than the second vibration signal,
- wherein the first vibration signal and the second vibration signal have a same frequency, and
- wherein a voltage level of the first vibration signal is higher than a voltage level of the second vibration signal.
