Provided is a signal processing device including a control unit configured to control each of a plurality of actuators configured to drive a display unit on the basis of an acoustic signal, in which the plurality of the actuators is provided for respective regions of the display unit, and the control unit executes low band component reduction processing of reducing a low band component of an acoustic signal of the region for driving the actuator on the basis of luminance of an image to be displayed in the region of the display unit.

Signal processing device, signal processing method, and image display device

A display apparatus according to an embodiment of the present disclosure includes: a thin plate-like display cell that displays an image; M exciters that are disposed on a back surface side of the display cell, and vibrate the display cell; and a driving section that drives the display cell and the M exciters.

Display apparatus and signal generation apparatus

A display apparatus according to an embodiment of the present disclosure includes: a display cell that displays an image and has a thin-plate shape; one or more vibration exciters that are disposed on rear-surface side of the display cell and cause the display cell to vibrate; and an opposing plate opposed to the display cell with an air gap in between. The display apparatus further includes a sound-spreading adjustment member that is disposed between the display cell and the two or more vibration exciters, and controls spreading of a sound generated by vibration caused by the two or more vibration exciters.

Display apparatus

Provided is a display device that includes a display on which an image is displayed on a display surface, a rear cover arranged on a back surface side of the display, and an upper speaker and a lower speaker arranged between the display and the rear cover and located so as to be separated vertically from each other, in which an upper slit functioning as a passage hole for sound output from the upper speaker is located above the display, a lower slit functioning as a passage hole for sound output from the lower speaker is located below the display, and a vertical width of the lower slit is larger than a vertical width of the upper slit.
