A display device includes: a display panel including a first substrate, a second substrate, and a light emitting element layer disposed between the first substrate and the second substrate, where the light emitting element outputs light to the second substrate; a first sound generator disposed on a surface of the first substrate, where the first sound generator vibrates the display panel to output a sound; and a first buffer member disposed on the surface of the first substrate, where a height of the first buffer member is less than a height of the first sound generator.

Embodiments of the present invention provide for systems and methods for submitting speech queries to one or more voice assistant devices, and retrieving the responses, in a soundproof environment. The systems and methods provide for sound-dampening voice boxes that are configured to house the respective voice assistant devices, in which the sound-dampening voice boxes submit speech queries to the respective voice assistant devices, and retrieve the responses therefrom.

Disclosed are a tweeter and an automobile audio system. The tweeter comprises: a bracket; a diaphragm comprising a top portion and an edge ring; a magnetic motor system; and a voice coil. A first cavity is formed between the top portion of the diaphragm, an inner wall of the voice coil, and the magnetic motor system. The bracket has an annular inner flange and an annular outer flange, the edge ring of the diaphragm is connected to the outer flange of the bracket, and the magnetic motor system is connected to the inner flange of the bracket, so that a second cavity is formed between the edge ring of the diaphragm, an outer wall of the voice coil, and the bracket. A through hole is opened on the voice coil, and the first cavity is in communication with the second cavity by the through hole.

Disclosed is a micro loudspeaker, which comprises a magnetic circuit system, a vibration system and a support system. The magnetic circuit system comprises a yoke, and a magnet and a washer accommodated within the yoke. The vibration system comprises a diaphragm and a voice coil adhesively fixed to the diaphragm. The support system comprises a front cover, and a housing matched and combined with the front cover. The housing comprises a bottom wall and a side wall. The bottom wall is provided with a mounting portion accommodating the magnetic circuit system, and is also provided with an assembly plane for assembly with a terminal. A height difference is provided between a position of the bottom wall of the housing corresponding to the assembly plane and a position of the side wall of the housing corresponding to the assembly plane, so as to cooperatively form an avoidance inclined surface.

A speaker device is disclosed. The speaker device includes a speaker enclosure structure including a speaker. The speaker is an electro-mechanical component, which in operation generates sound waves by deflection of a speaker membrane and in collaboration with the speaker enclosure structure. The speaker device further includes a speaker device housing. The speaker device housing is an outer shell of the speaker device and may accommodate additional electronic components required for operation of the speaker or for other purposes. The speaker enclosure structure is mechanically coupled to the speaker device housing. The speaker device further includes at least one coupling element, wherein the speaker enclosure structure is mechanically coupled to the speaker device housing by the at least one coupling element, the coupling element having a vibration damping structure configured to inhibit mechanical vibrations being transmitted through the coupling element.

The present disclosure relates to a display apparatus, and more particularly, to a display apparatus having a display panel capable of generating sound. A display apparatus according to the present disclosure includes: a display module; a guide panel disposed at circumferences of a rear surface of the display module; a back cover attached to the guide panel; a sound generating unit disposed between the display module and the back cover; and an adhesive fixing element and a vibration absorber disposed between the guide panel and the rear surface of the display module, wherein the adhesive fixing element fasten the guide panel to the rear surface of the display module, and wherein the vibration absorber is disposed at the guide panel as facing to inner portions of the display module.

A speaker device includes: a housing provided with an accommodating space, and a sounding member accommodated in the accommodating space. The sounding member includes a magnetic circuit unit and a vibration unit provided with a diaphragm. The housing includes an upper housing and a lower housing. The lower housing includes: a metal bottom wall, lower metal side walls, and, and sealing connectors respectively provided between two adjacent lower metal side walls of the plurality of lower metal side walls. An end of the lower metal side wall close to the upper housing bends and extends in a direction perpendicular to a vibrating direction of the diaphragm to form a bending edge. The bending edge and a bottom surface of the sealing connectors jointly form a sealing surface. The sealing surface is connected to the upper housing to seal. The speaker device can increase the powder filling space.

A system can improve the performance of an electroacoustic absorber. The system includes a loudspeaker and an absorber operatively positioned relative to the loudspeaker. The absorber can be configured to absorb sound waves. A control circuit can be operatively connected to the loudspeaker. The control circuit can be configured to tune the resonance of the loudspeaker and therefore cause one or more acoustic characteristics, such as acoustic impedance, of the loudspeaker to be adjusted.
