A headset cup having a front cavity and a rear cavity separated by a driver, with a mass port tube connected to the rear port to present a reactive acoustic impedance to the rear cavity, in parallel with a resistive port, the total acoustic response of the rear cavity remaining linear at high power levels. In some embodiments, the mass port tube is made of metal, while the headset cup is otherwise made of plastic.

Ear cushion assemblies, and headphones incorporating ear cushion assemblies, the ear cushion assembly including an ear cushion coupled to a mounting plate, where the mounting plate defines plural openings for a passage of sound, and defines plural openings for fasteners; and where the ear cushion grips an outer circumference of the mounting plate to form an annular, circumferentially-fixed, and substantially airtight sealing surface.

The present disclosure relates to an earpiece for an ear. The ear comprises a concha cavity at least partially delimited by a concha floor, a concha side wall and a concha ceiling. The earpiece comprises a peripheral skirt comprising a positioning skirt portion which in turn comprises an outer skirt surface and an inner skirt surface, wherein a transition from the outer skirt surface to the inner skirt surface occurs at a skirt edge. The skirt edge extends at least partially circumferentially around a central axis of the earpiece, wherein the earpiece is adapted to be moved to a use position, at least partially within the concha cavity, in a direction parallel to the central axis, during insertion of the earpiece into the ear. When the peripheral skirt is in a non-influenced condition, at least a portion of the inner skirt surface faces the central axis.

An earphone charging box includes a box body, a cover body, and a connecting component. The box body includes a bottom shell and a middle shell mounted in the bottom shell. The cover body is used for opening or closing the box body. The connecting component includes a connecting piece arranged on the cover body in a protruding manner and faces a surface of the middle shell, and a rotating shaft connected to the connecting piece and extends outwards. The rotating shaft is spaced from the cover body. The middle shell is provided with an accommodating space. A side surface of the accommodating space and a side wall of the bottom shell form a rotating space. The rotating shaft is rotatably accommodated in the rotating space. The cover body is rotatably connected to the box body through the rotating shaft.

An audio output device is provided. The audio output device includes a buffering member including a biometric sensor and a first terminal connected to the biometric sensor, a housing including a portion to which the buffering member is mounted, a second terminal disposed in the portion of the housing and electrically connected to the first terminal of the buffering member, and a control circuit positioned inside the housing and operatively connected to the biometric sensor, the first terminal, and the second terminal, wherein the control circuit may be configured to supply power to the biometric sensor through the second terminal if the first terminal and the second terminal are connected, and to receive at least one piece of biometric signal data obtained from the biometric sensor of the buffering member through the second terminal.

At least one exemplary embodiment is directed to an earpiece having a swappable inflatable tip.

An acoustic device with an open audio device structure that is configured to be carried on the head or upper torso of a user, a housing carried by the open audio device structure, the housing having opposed first and second ends, a flat diaphragm in the housing and comprising a front face and a rear face, the diaphragm configured to radiate front acoustic radiation from its front face and rear acoustic radiation from its rear face, wherein the front and rear acoustic radiations are out of phase, structure that supports the diaphragm such that the diaphragm can move relative to the housing, a primary magnet adjacent to the rear face of the diaphragm, a magnetic circuit that defines a path for magnetic flux of the primary magnet, a voice coil that is exposed to the magnetic flux and is configured to move the diaphragm up and down along a radiation axis that is normal to the front face of the diaphragm, and first and second sound- emitting outlets in the housing, wherein the first sound-emitting outlet is in or proximate the first end of the housing and is acoustically coupled to the front face of the diaphragm so as to emit front acoustic radiation into an acoustic space, and wherein the second sound-emitting outlet is in or proximate the second end of the housing and is acoustically coupled to the rear face of the diaphragm so as to emit rear acoustic radiation into the same acoustic space.

Various implementations include sleep aiding in-ear audio devices. Certain implementations include sleep aiding in-ear audio devices with a noise-reduction finish, along with methods of applying a noise reduction finish to an in-ear audio device. In some cases, a sleep aiding in-ear audio device includes: a set of earbuds, each earbud having: an eartip for mating with an ear of a user; and a housing coupled with the eartip, the housing containing an electro-acoustic transducer for providing an audio output to the user via the eartip, where when inserted in the ear of the user, substantially all of an exposed surface of the earbud is finished with a matte coating.

A method and a device for reducing noise of a wireless-earphone, a wireless-earphone and a computer-readable storage medium are provided. In the method, a first electromagnetic signal from a slave earphone is received, and the first electromagnetic signal is converted to an audio signal. The first electromagnetic signal is obtained by a coil inducing an audio signal acquired by a microphone in the slave earphone. A to-be-denoised earphone is determined based on audio signals acquired by microphones in the earphones. It is determined whether an audio signal acquired by a microphone in the to-be-denoised earphone has a voice feature. Noise reduction processing is performed on the audio signal acquired by the microphone in the to-be-denoised earphone by using a filter in a case that the audio signal acquired by the microphone in the to-be-denoise earphone has the voice feature.
