Disclosed in the present application is a display device, comprising a display body and an electromagnetic vibration apparatus; the display body comprises a housing, a display screen mounted at a front end of the housing, and an optical module mounted within the housing, the housing comprising a back plate; the electromagnetic vibration apparatus is mounted on the back plate and emits sound by means of vibrating the back plate, the optical module, and the display screen.

A display device is disclosed. The display device may comprise a display panel; a frame disposed behind the display panel and coupled to the display panel; a stand configured to support the frame at a lower part of the display panel; a bottom accommodation portion fixed to a lower part of the stand, the bottom accommodation portion having an inner space that is opened rearward; and a box slidably inserted into the inner space, the box having an accommodation space provided inside the box.

A display apparatus includes a display module having a display panel configured to display an image; a sound generating device on a rear surface of the display panel and including a first side and a second side perpendicular to the first side and an adhesive member in a partial region of the sound generating device, the adhesive member having a size smaller than one of the first side and the second side of the sound generating device.

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 device comprises a display, a rear side member, and a plurality of speaker units. The speaker units each have a speaker main body having first and second surfaces that are attachable to the rear side member and are parallel to each other and a side surface that connects the first surface and the second surface, and at least one sound emitting portion displaced from a center of the side surface on the side surface. When the speaker main body is inverted from a first state in which the first surface is fixed to the rear side member to a second state in which the second surface is fixed to the rear side member, the at least one sound emitting portion in the first state and the at least one sound emitting portion in the second state are arranged to be symmetrical with respect to an axis of inversion.

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 sound output apparatus includes a display panel for displaying video content; one or more first sound output driving units for vibrating the display panel on the basis of a first sound signal which is a sound signal of the video content displayed on the display panel and for executing sound reproduction; a plurality of second sound output driving units for vibrating the display panel on the basis of a second sound signal different from the first sound signal and for executing the sound reproduction; and a localization processing unit for setting a constant location of a sound output by the plurality of second sound output driving units by signal processing of the second sound signal.

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.

In an example implementation according to aspects of the present disclosure, a speaker includes an enclosure having a first cavity, a second cavity separate from the first cavity, and a third cavity connecting the first cavity to the second cavity. As an example, a speaker driver is disposed in the first cavity, and a passive radiator disposed in the second cavity.

A display device comprises: a motor; a display; a plurality of speakers provided in a plurality of regions of the display; and at least one processor. The at least one processor being configured to output a plurality of audio signals corresponding to a plurality of audio channels to the plurality of speakers, control the motor to rotate the display, based on an input of a user command for rotating the display, and control the plurality of speakers to output the plurality of audio signals in response to a change in positions of the plurality of speakers based on a rotation of the display.
