An eyeglass headphone with a frame that is constructed and arranged to be carried by the head of a wearer, the frame comprising a bridge that is adapted to be supported by the wearer's nose, and a left temple and a right temple that extend rearwardly from the bridge, toward the left and right ears of the wearer, respectively, and a dipole loudspeaker built into the frame, where the dipole loudspeaker comprises a driver that emits front-side acoustic radiation from its front side, and emits rear-side acoustic radiation from its rear side. The frame comprises at least first and second sound-emitting openings, wherein the first sound-emitting opening is constructed and arranged to emit front-side acoustic radiation and the second sound-emitting opening is constructed and arranged to emit rear-side acoustic radiation.

A speaker cover enabling directivity control of soundwave radiation, containing a cover body having a truncated pyramid shape; the cover body is adapted to be provided with a speaker inside; the cover body is hollow, and is provided with an opening; the cover body has a base board and a plurality of side boards extending out from edges of the base board; a fixing unit is provided on the base board to fix the speaker; the side boards are made of hard board material; at least part of an inner side wall of each of the side boards is provided with sound absorption material.

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.

Various implementations include loudspeakers and related waveguides. The loudspeakers can include an adjustable waveguide for modifying the coverage pattern of the audio output. In some particular aspects, a loudspeaker includes: a single speaker box with at least one driver; a waveguide having: a pair of opposing walls that are fixed with respect to the at least one driver; and at least one adjustable wall that is adjustable relative to the at least one driver; and at least one fin coupled to the waveguide for accommodating a gap between the pair of opposing walls and the at least one adjustable wall.

The present invention discloses an endpoint mixing product having a control module and a speaker system. The speaker system includes speakers in which each speaker is with a 3D coordinate. The speakers communicate with the control module respectively. The control module is configured to deliver sound fragments to the speakers. The sound fragments contain 3D coordinates and correspond to the speakers respectively through the 3D coordinates. The speakers are configured to receive and play the corresponding sound fragments respectively to form an endpoint mixing sound.

Disclosed is a display apparatus capable of improving a sound quality through an accurate sound transmission, wherein the display apparatus may include a backlight module connected with a rear surface of a display panel, a rear structure for surrounding the backlight module, and a vibration generating device for vibrating the display panel through the backlight module, wherein the vibration generating device is fixed to the rear structure.

A mobile music store assembly includes a housing base; a first housing member that is selectively movable relative to the housing base between a first position wherein the mobile music store assembly is in a closed configuration, and a second position wherein the mobile music store assembly is in an open configuration; and a second housing member that is selectively movable relative to the first housing member and the housing base between a first position wherein the mobile music store assembly is in the closed configuration, and a second position wherein the mobile music store assembly is in the open configuration. The mobile music store assembly can further include a music player that is positioned substantially within the housing assembly. The music player is only accessible when the mobile music store assembly is in the open configuration.

A speaker system is disclosed with user-selectable output modes including controlled directivity output modes (e.g. selectable monopole, dipole, or cardioid radiation patterns), that may be implemented with adjustable electronic delay of out-of-phase driver elements, and that provides for both even-orderharmonic distortion reduction and driver force cancellation in a compact assembly suitable for home or studio use.

The present subject matter provides a technical solution to the technical problems facing sound localization by separating sounds and reproducing the separated sounds using a set of loudspeakers and a set of headphones. A general soundtrack that is meant to be experienced throughout the room would play through the loudspeakers, and specific sounds that are meant to be experienced near the listener would be played through a binaural representation in the headphones. The headphones may be selected to avoid occluding the ear, allowing sound produced at the loudspeakers to be heard clearly. This separation and reproduction of sounds using a combination of a loudspeaker and headphone provides a technical solution to the technical problem facing typical surround sound systems by localizing sounds for listeners in any location within a room. This improves reproduction accuracy of location-specific audio objects, including audio objects above or below a coplanar speaker configuration.
