Abstract
Disclosed is a display device that includes a display panel, sound generating actuators including a first sound generating actuator in a first area of the display panel and a second sound generating actuator in a second area of the display panel, the first and second sound generating actuators configured to vibrate the display panel to generate sound, and a partition between the first sound generating actuator and the second sound generating actuator.
Claims23
A display device, comprising:
- a display panel to emit light;
- sound generating actuators including a first sound generating actuator in a first area of the display panel and a second sound generating actuator in a second area of the display panel, the first and second sound generating actuators configured to vibrate the display panel to generate sound;
- a partition between the first sound generating actuator and the second sound generating actuator;
- and
- a support portion configured to support a rear portion of the display panel,
- wherein the first or second sound generating actuator is inserted into a support hole provided in the support portion to be fixed to the support portion, and
- wherein the first or second sound generating actuator includes at least one of a lower plate inserted into the support hole, a magnet on the lower plate, a center pole at a center of the lower plate, a bobbin to surround a periphery of the center pole and having a tip end in contact with the display panel, and a coil wound around an outer periphery of the bobbin.
