Aspects of the present disclosure provide methods and apparatuses for determining a nozzle of an audio device is, at least partially blocked. More specifically, based on a measured transfer function between the driver and a microphone and an expected transfer function between the driver and the microphone, a blockage is detected. In response to the detected blockage, the user is notified.

A device and method for wireless charging user a speaker coil. In one embodiment, a device may include a processor, memory, at least one speaker coil configured to reproduce audio signals and receive wireless power from a wireless power source, and a switch configured to switch the at least one speaker coil between reproducing the audio signals and receiving the wireless power from the wireless power source. A method may include identifying a device that includes at least one speaker coil, receiving, via the at least one speaker coil, audio signals, and receiving, via the at least one speaker coil, wireless power. Various other methods, systems, and computer-readable media are also disclosed.

An auxiliary device charging case is used to facilitate translation features of a mobile computing device or auxiliary device. A first user, who may be a foreign language speaker, holds the charging case and speaks into the charging case. The charging case communicates the received speech to the mobile computing device, either directly or through the auxiliary device, which translates the received speech into a second language for a second user, who is the owner of the mobile computing device and auxiliary device. The second user may provide input in the second language, such as by speaking or typing into the auxiliary or mobile computing device. The mobile computing device may translate this second input to the first language, and transmit the translated input to the charging case either directly or through the auxiliary device. The charging case may output the translated second input to the first user, such as through a speaker or display screen.

There is presented a hearing aid configured to be arranged at least partly in the ear canal of a specific person, the hearing aid comprising a faceplate, a custom ear shell, adapted to fit or match with the ear canal of a specific person, the custom ear shell connected to the faceplate, a rechargeable battery, an induction coil for wireless charging of the rechargeable battery, wherein the induction coil is fixed to the ear shell and furthermore a method for providing a hearing aid, said method comprising obtaining data representative of a shape and/or size of an ear canal of a specific person, establishing a digital model of the custom shell of the hearing aid for said ear canal based on said data, wherein said providing includes determining a position and/or orientation of an induction coil in an inner space of said ear shell, which position and/or orientation increases or maximizes a distance from the outer ear to the faceplate.

Embodiments describe an eartip including an eartip body having an attachment end and an interfacing end opposite from the attachment end. The eartip body can include an inner eartip body having a sidewall extending between the interfacing end and the attachment end, the sidewall defining a channel and having a first thickness near the attachment end and a second thickness different from the first thickness at the interfacing end. The eartip can also include an attachment structure coupled to the inner eartip body at the attachment end, the attachment structure having an inner surface and an outer surface. The attachment structure can include an upper region interfacing with the sidewall and defining discrete through-holes, a lower region below the upper region where the inner surface defines a plurality of recesses positioned around the lower region, and a mesh extending across the channel and into the upper region.

A three-proof earbuds box protective case includes a bottom housing and a top cover mounted at the upper end of the bottom housing and can be opened or closed. One side of the bottom housing and one side of the top cover are hinged. A waterproof and dustproof ring is provided between the bottom housing and the top cover. The lower end of the bottom housing has a first shockproof flexible rubber having a first shockproof part fixed to the lower end surface of the bottom housing, and a second shockproof part fixed to the inner wall of the bottom housing. The upper end of the top cover has a second shockproof flexible rubber having a third shockproof part fixed to the upper end surface of the top cover, and a fourth shockproof part fixed to the inner wall of the top cover.

An earphone charger includes an earphone seat fixedly disposed with two charging resilient pieces for respectively abutting against positive and negative conductive strips of a BLUETOOTH earphone, and with an anti-disengagement component preventing the earphone from disengaging from the charging resilient pieces during charging. The charging resilient pieces extend obliquely thereby a distance therebetween gradually decreases along an insertion direction of the earphone. The charger can charge BLUETOOTH earphones of various generations and a working process is that: the earphone is moved to the earphone seat, the charging resilient pieces are deformed laterally under the pressing of the earphone, and then the positive and negative conductive strips abut against the two charging resilient pieces, and moreover, the earphone is tightly attached to the charging resilient pieces through the anti-disengagement component to achieve continuous charging. After the charging, the earphone is removed and the charging resilient pieces can rapidly rebound.

The present disclosure relates to an acoustic output apparatus. The acoustic output apparatus comprising: at least one low-frequency acoustic driver that outputs sound from at least two first sound guiding holes; at least one high-frequency acoustic driver that outputs sound from at least two second sound guiding holes; and a controller configured to cause the low-frequency acoustic driver to output sound in a first frequency range, and cause the high-frequency acoustic driver to output sound in a second frequency range, wherein the second frequency range includes frequencies higher than the first frequency range.

An ear-wearable electronic device includes one or more processors configured to detect presence of first and second hearing devices in a charging case, and to initiate a self-check protocol by at least one of the first and second hearing devices. The self-check protocol comprises wirelessly coupling the first and second hearing devices, selectively activating at least one electronic component of the first hearing device, and assessing performance of the second hearing device using an output or a response of the at least one electronic component of the first hearing device. The self-check protocol also comprises selectively activating at least one electronic component of the second hearing device, assessing performance of the first hearing device using an output or a response of the at least one electronic component of the second device, and storing results of the performance assessment in a memory.

A case for an electronic device. The case includes a lower housing having a cavity to receive the electronic device, and an electrical connector configured to couple to the electronic device. A lid is attached to the lower housing with a pivotable joint allowing the lid to rotate between a closed position where the lid is aligned over the cavity and an open position where the lid is angularly displaced allowing the electronic device to be removed from the cavity. The case also includes a hinge that provides the pivotable joint. The hinge is configured such that, when the lid is in the closed position, it is biased to remain closed via a detent, and, such that the lid has one or more stable positions between the fully open and fully closed positions.
