A home appliance includes an electrical equipment compartment disposed in an upper portion of the home appliance, and including an upper side that is open, an electrical equipment compartment cover to cover the open upper side of the electrical equipment compartment, and including a speaker hole, a microphone accommodating portion which protrudes upward from an upper side of the electrical equipment compartment cover and including an accommodating space and a front portion that includes microphone holes laterally spaced apart from each other and which face toward a front of the home appliance, a microphone unit including a printed circuit board (PCB) disposed in the accommodation space behind the microphone holes and including microphone chips mounted on the PCB, and a speaker unit disposed in the electrical equipment compartment to correspond to the speaker hole.

A terminal speaker includes an enclosure with accommodating space with an affixed sound production monomer. The sound production monomer has a diaphragm configured to vibrate to produce sound. The enclosure includes a first inner bottom wall and an inner sidewall fastened to the first inner bottom wall. The diaphragm is fastened to the inner sidewall, dividing the accommodating space into front and rear cavities. The first inner bottom wall is in the front cavity. A sound outlet hole penetrates the inner sidewall. The front cavity is in communication with the sound outlet hole by a front cavity channel. The diaphragm is tilted relative to the first inner bottom wall. The perimeter of the end of the front cavity in communication with the sound outlet hole is greater than the perimeter of the end of the front cavity remote from the sound outlet hole.

The disclosure relates to a microphone device. The microphone device comprises a closed housing with a sidewall, a microphone arranged within the closed housing, and a membrane at an outer surface of the sidewall wherein a first part of the sidewall has a first thickness and wherein the membrane is comprised by, in particular is formed by, a second part of the sidewall having a second thickness smaller than the first thickness. The disclosure further relates to a method for generating the microphone device. The microphone device protects the microphone from water or particles at high protection level.

A sound reproduction device includes a cabinet and a loudspeaker disposed inside the cabinet, the cabinet includes a baffle including a plurality of through holes provided in a ringshaped area, and the loudspeaker is disposed in an orientation in which sound is emitted toward the plurality of through holes.

Disclosed is a voice input apparatus including: a speaker having a diaphragm for outputting sound downward; a speaker room in which the diaphragm is accommodated; and a microphone disposed outside the speaker room, wherein the speaker room includes: a room base disposed below the diaphragm; a sound guide which is protruded upward from the room base, positioned below the diaphragm, and reflects the sound outputted from the diaphragm outward in a radial direction; and a room sidewall which is extended upward from a circumference of the room base to surround the sound guide, and has a sound discharge port for emitting the sound reflected by the sound guide to the outside of the speaker room.

A loudspeaker system includes a loudspeaker base and a loudspeaker peripheral that is independent of the loudspeaker base. The loudspeaker peripheral is shaped as a role figure. The loudspeaker base and the loudspeaker peripheral connect through a contact connection or a non-contact connection, and provide personalized voice data corresponding to the role figure when connected.

A speaker device includes a frame, a vibration unit and a magnetic circuit unit. The vibration unit includes a diaphragm fixed to the frame and a voice coil. The magnetic circuit unit includes a yoke and a magnet assembly that is accommodated and fixed in the yoke and is spaced apart from the yoke to form a magnetic gap. The voice coil is inserted in the magnetic gap. The yoke includes a yoke bottom wall, a yoke side wall and flanges. The flange includes a first section and a second section extending from the first section. A side of the first section close to the second section and the second section enclose a fixing step. The second section is fixed to the frame. The speaker device of the present disclosure has better reliability.

A display device includes: a display panel including a substrate and a pixel array layer disposed on a surface of the substrate; a sound generation device disposed on an opposing surface opposite to the surface of the substrate; and a set cover including a plurality of ribs which overlap the sound generation device in a thickness direction of the display panel. The sound generation device vibrates the display panel to output a sound.

A polycarbonate speaker basket with a plurality of slots positioned circumferentially about an opening on a perimeter of a rear surface and a polypropylene splash shield that attaches to the rear surface of the speaker basket. The splash shield has a perimeter wall having a predetermined height. A plurality of tabs on a first surface of the perimeter wall aligns with and are inserted into the plurality of slots, and a plurality of guards extend across the opening of the splash shield.

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.
