A sound-generating device, a display device, a sound-generating controlling method, and a sound-generating controlling device are provided. The sound-generating device includes: a reflection plate which includes a first sound wave reflection face arranged towards a first direction; a plurality of main loudspeakers, the plurality of main loudspeakers are distributed in an array in a preset three-dimensional space, and the preset three-dimensional space is located at one side of the first sound wave reflection face towards a first direction; the plurality of main loudspeakers include first main loudspeakers with a sound-generating direction towards the first direction, and second main loudspeakers with a sound-generating direction towards a second direction, the second direction is an opposite direction of the first direction; and the sound waves emitted by the second main loudspeakers are transmitted to the first sound wave reflection face and can be reflected by the first sound wave reflection face.

A compression driver for an omnidirectional loudspeaker having an inverted dome diaphragm, a phasing plug having a top portion facing a convex surface of the inverted dome diaphragm and a plurality of concentric apertures that cooperate with the convex surface of the inverted dome diaphragm. Each aperture has a predetermined radial width and is spaced a predetermined concentric distance from an adjacent aperture converging at an exit of the phasing plug. The compression driver has a dispersion control assembly mounted to the bottom portion of the phasing plug along the central axis.

Provided is a speaker box, including housing and sounding unit having diaphragm including vibration portion and suspension portion. The housing includes holder, lower and upper covers. The holder includes holder body, holder extension portion and holder fixing portion. The sounding unit is fixed to the holder fixing portion. Orthographic projection of the vibration portion completely falls into the holder body. The suspension portion is arc-shaped formed by recessing away from the holder body. The lower cover includes lower cover plate and lower cover sidewall. The sounding unit, the holder and the lower cover sidewall define front sound cavity. The sounding unit and the lower cover define rear sound cavity. The lower cover sidewall, the holder fixing portion, the holder extension portion and the upper cover define auxiliary rear sound cavity communicated with the rear sound cavity. The speaker box has large cavity volume and good acoustic performance.

An information handling system to wirelessly transmit and receive data at an antenna may include a processor; a memory; a power management unit; a bottom metal chassis of a base housing containing components of the information handling system; a vent formed into the bottom metal chassis; a slot formed between the vent and a terminal edge of the bottom metal chassis; and an antenna located within the bottom metal chassis and behind the vent to, upon execution of the processor, create radiating radio frequency (RF) bands along an edge of the vent.

In a display assistant device, a speaker is mounted in a waveguide structure which is at least partially disposed beneath a display screen. The waveguide structure is mounted in an exterior housing which includes speaker grills distributed on a plurality of surfaces of the exterior housing, permitting sound waves from the speaker to be projected outside the exterior housing. A cover structure is disposed on top of the waveguide structure to conceal the waveguide structure and speaker within the exterior housing. The cover structure has a tilted bottom surface configured to be suspended above the waveguide structure and to be separated by a first space. Sound waves projected from an upper portion of the speaker are reflected by the tilted bottom surface and are guided through the first space to exit the device from a speaker grill portion located on a rear side of the exterior housing.

The present invention discloses a speaker device. The speaker device comprises a speaker box, a heat source, and a heat conducting member; the speaker box comprises a housing, a speaker, a sound-guiding channel, and a heat conducting plate; the speaker includes a diaphragm, the first receiving space is divided into a front sounding chamber and a back chamber, and the sound-guiding channel communicates the front sounding chamber with the outside and forms a front chamber together with the front sounding chamber; the housing having an opening penetrating therethrough, the opening communicates with the front chamber, and the heat conducting plate covers on the opening, an adjusting hole penetrates through the housing and communicates with the back chamber; an valve covers on the adjusting hole and a controller for outputting a control signal to control the valve to open or to close.

This application is directed to a display assistant device that acts as a voice-activated user interface device. The display assistant device includes a base, a screen and a speaker. The base is configured for sitting on a surface. The screen has a rear surface and is supported by the base at the rear surface. A bottom edge of the screen is configured to be held above the surface by a predefined height, and the base is substantially hidden behind the screen from a front view of the display assistant device. The speaker is concealed inside the base and configured to project sound substantially towards the front view of the display assistant device.
