A display apparatus includes a display panel including first, second, and third areas; a first rear cover on a rear surface of the display panel; a second rear cover covering at least a portion of the first rear cover; a first partition between the rear surface of the display panel and the first rear cover to partition the first area, the second area and the third area from one another; a first sound generating module in the first area and the second area to contact the rear surface of the display panel; a second sound generating module in the third area to be spaced apart from the rear surface of the display panel, and a port hole provided in the third area by removing a portion of the first rear cover to allow the second sound generating module to face the rear surface of the display panel.

A display apparatus includes a display module including a display panel configured to display an image, a supporting member on a rear surface of the display module, and a first vibration generating module including two or more vibration generating devices on the rear surface of the display module to output sounds of different sound bands.

A display apparatus is provided. The display apparatus includes a display; a main body on which the display is mounted; a cover; a mounting member configured to separably mount the main body to the mounting member; and a guide member disposed at a back surface of the main body, the guide member including a plate member and side-surface members extending from opposite side surfaces of the plate member, wherein each of the side-surface members has an inclined shape.

A display apparatus includes a display panel including a display area configured to display an image, and a non-display area, at least one first sound generator in the display area, and at least one second sound generator in the non-display area, wherein each of the at least one first sound generator and the at least one second sound generator is configured to vibrate the display panel to generate sound toward a front of the display panel.

A terminal device includes: a housing; an audio output module; and a driving module, connected to the audio output module to drive the audio output module to move between a first position and a second position. The first position is located inside the housing, and the second position is located outside the housing. When the audio output module is in an audio output state, the audio output module is driven to move to the second position. When the audio output module exits the audio output state, the audio output module is driven to move to the first position.

User equipment (UE) includes a housing, an audio output module, and a drive module connected to the audio output module. The drive module is configured to drive the audio output module to move along a straight line between a first location and a second location. The first location is inside the housing. The second location is outside the housing. When the audio output module is in an audio output state, the drive module is configured to drive the audio output module to move along the straight line to the second location. When the audio output module exits the audio output state, the drive module is configured to drive the audio output module to move along the straight line to the first location.

A display apparatus is provided. The display apparatus according to the disclosure includes a display, a plurality of speakers, a sensor, and a processor configured to control the display apparatus to: display an image and generate a sound corresponding to the image and output the sound through the plurality of speakers, and based on a user being sensed by the sensor, determine a location of the user, and based on the determined location of the user, change a first weight of a high band sound and a second weight of a low band sound of the sound, and output the changed sounds through the plurality of speakers.

An audio-visual system may include a housing comprising an open upper end and a storage space, an audio-visual device installed inside the housing and exposable through the open upper end, and a lifting device configured to expose or store the audio-visual device inside the housing through the open upper end. The audio-visual device may include a display, a speaker, and a processor configured to control the audio-visual system to operate in a first mode for outputting media art content while the display is stored in the housing according to a first event, operate in a second mode for outputting audio content through the speaker while part of the display is exposed through the open upper end according to a second event, and operate in a third mode for outputting a visual content while the entire display is exposed through the open upper end according to a third event.

A loudspeaker fixing structure and a display device are provided. The loudspeaker fixing structure includes: a fixing frame configured to be connected to a back plate of the display device; a pair of fixing side plates, opposite to each other and configured to be connected to a loudspeaker body; fixing members, fixed on the fixing frame and arranged in a one-to-one correspondence with the fixing side plates, and in each pair of the fixing side plate and the fixing member, the fixing member is at a side of one fixing side plate away from the other fixing side plate, the fixing member is fixed to the fixing side plate through a curved protrusion and a curved groove, and a protrusive direction of the curved protrusion is perpendicular to the fixing side plate.

A display apparatus includes a display panel, a back cover accommodating the display panel, and a sound output unit including at least one sound output module disposed to overlap the display panel. The at least one sound output module includes a support plate including an uneven surface and a piezoelectric element attached on the uneven surface of the support plate and has a shape corresponding to the uneven surface of the support plate. Accordingly, a sound having a straight characteristic within an audible frequency domain may be output, thereby enhancing a sense of reality and an immersion of a viewer watching an image displayed by the display apparatus.
