An illustrative hearing device may be at least partially inserted into an ear canal and may include an acoustic transducer having a membrane configured to generate sound waves, a housing enclosing a first chamber and a second chamber acoustically coupled by the membrane, a sound outlet configured to release sound waves from the first chamber into the ear canal, an acoustic port acoustically coupling the second chamber to an ambient environment outside the ear canal, and a mechanical resonator configured to resonate with sound waves at a resonance frequency. The second chamber may be acoustically coupled to the mechanical resonator.

The present application provides a sounding device. The sounding device includes a front surface with a sound outlet hole; a back surface; a sounding component and an outer casing. The outer casing is covered outside the sounding component. A cavity is formed between the outer casing and the end of the sounding component close to the back side. A sound guiding channel is arranged in the outer casing. One end of the sound guiding channel is communicated with the sound outlet hole, and the other end of the sound guiding channel is communicated with the cavity. The sounding device of the present application provides a smooth transmission channel for the sound from the back side by arranging the sound guiding channel in the outer casing, thereby strengthening the frontal sound of the sounding device and greatly improving the loudness of the sounding device.

A speaker module relates to the technical field of electroacoustic products, and comprises a lower module casing, an upper module casing and a steel sheet which are successively combined together. A speaker monomer is contained in a space enclosed by the lower module casing, the upper module casing and the steel sheet. The speaker monomer, the upper module casing and the steel sheet together enclose a front sound cavity of the module. The front sound cavity is in communication with a sound outlet hole of the module, and the sound outlet hole is located on a side part of the speaker monomer. A sheet is adhered inside the steel sheet, the thickness of the sheet being about 0.1 mm˜0.2 mm and the material of the sheet being a soundproof material. The present speaker module solves the technical problem of the poor intermediate and high frequency performance of the speaker module in the prior art. The speaker module has a good intermediate and high frequency performance, a high overall acoustic performance, a thin thickness, and also a good stability, and a long service life.

A hexagonal speaker with six edges (sides) and four drivers. A pair of drivers is embedded on adjacent edges and another pair of drivers is embedded on the opposite edges, while two opposing edges in between each pair of drivers do not have a driver. A down-firing subwoofer is located on the bottom of the speaker. The speaker is raised off the ground so that the subwoofer can output sound without touching the ground. An air vent tube is also located on the bottom of the speaker adjacent to the subwoofer.

A speaker device includes a first cabinet, a speaker unit, a second cabinet and a tube cabinet. The first cabinet is disposed in a casing and with a first chamber formed therein. The speaker unit is disposed in the first chamber. The second cabinet is connected to the casing and with an opening formed on the casing. The second cabinet has a second chamber formed therein and communicating with the opening. The tube cabinet connects the first cabinet and the second cabinet. The tube cabinet has a tube chamber formed therein and communicating with the first chamber and the second chamber. A sound generated by the speaker unit is enhanced in the first chamber, transmitted to the second chamber via the tube chamber and emitted out via the opening.

A display apparatus and a computing apparatus including the same are provided. A display apparatus includes: a display module including a display panel configured to display an image, a system rear cover covering a rear surface of the display module, a vibration plate between the system rear cover and the rear surface of the display module, and a vibration module configured to vibrate the vibration plate, wherein the display panel is further configured to vibrate based on a vibration of the vibration plate to output sound.

A stiffening part (25) arranged to be integrated into the interior of a casing (12) of an audio speaker (11) in order to stiffen said casing, the audio speaker also being capable of comprising at least one loudspeaker (18a) mounted on a first face (14) of the casing, the stiffening part comprising a connecting portion, at least one damping support defining a receiving space arranged to receive a damping device (40a) for intended to limit vibrations of the loudspeaker, wherein the damping support comprises a plurality of ribs (34) distributed around the receiving space (31), each rib extending in a distinct plane parallel to a depth of the receiving space, the stiffening part being arranged such that, when the enclosure (11) is assembled, the connecting portion interconnects inner walls of a second (15) of the casing and a third face (16) of the casing opposite each other and both perpendicular to the first face (14), the damping device being positioned in the receiving space, and a rear portion of the loudspeaker abutting the damping device.

The present disclosure generally relates to acoustic assemblies. One acoustic assembly includes a base and a first die disposed on the base. The first die comprises a microelectromechanical system (MEMS) microphone that includes a first diaphragm and a first back plate. The MEMS microphone has a barometric release. The acoustic assembly also includes a second die disposed on the base. The second die comprises a pressure sensor. The acoustic assembly further includes a cover coupled to the base and enclosing the first dies and the second die. A back volume is formed between the base, the first die, the second die, and the cover. The pressure sensor is configured to sense a pressure of the back volume.

Headphones include at least one headphone unit each having a speaker unit, a chamber that covers a back surface of the speaker unit, a housing that is disposed on a side of the back surface of the speaker unit, in which the chamber is disposed, and that covers the chamber, and a vibration damper that connects the chamber and the speaker unit.

Disclosed is a user terminal employing a 2-in-1 audio output structure which combines a speaker and a receiver. The said user terminal comprises a receiver sound outlet configured on a first side of the said user terminal, and a receiver leakage aperture configured, on a second side of the said user terminal, as a passage for releasing concentrated energy which cannot be released by the said receiver sound outlet in time, wherein the said second side is different from the said first side.
