Abstract: Various embodiments of an ear-wearable electronic device are disclosed. The device includes a shell, a faceplate connected to a second end of the shell to form an enclosure, and an electromechanical package disposed at least partially within the enclosure. The package includes a flexible printed circuit board assembly (PCBA) disposed within the enclosure proximate to a first end of the shell and extending along an assembly axis, where the PCBA includes a concave inner surface and a convex outer surface; and a micro-mechanical systems (MEMS) receiver disposed on or at least partially in the concave inner surface of the PCBA. The device further includes an acoustic path disposed at least partially within the enclosure and extending between an inlet that is acoustically coupled to a receiver port of the MEMS receiver and an outlet that is disposed at the first end of the shell.

Abstract: A system includes a hearing device comprising a rechargeable power source, power management circuitry, and a first charging interface comprising a first cathode contact and a first anode contact spaced apart from the first cathode contact. A charging module comprises a second charging interface configured to detachably couple with the first charging interface of the hearing device. The second charging interface comprises a second anode contact having a contact surface and a displaceable second cathode contact. An arrangement is configured to displace at least a portion of the second cathode contact above the contact surface to facilitate electrical contact between the first and second cathode contacts prior to electrical contact between the first and second anode contacts. Charging circuitry of the charging module is coupled to the second charging interface and configured to charge the rechargeable power source of the hearing device.

Abstract: A device includes a housing, a first cover coupled to the housing, a second cover coupled to the housing, and a microphone assembly. The first cover includes a first channel. The microphone assembly includes a printed circuit board (PCB) having a microphone and a second channel, and a seal. The seal has a third channel configured to align with the first channel and the second channel, and a cavity. The seal is configured to transition between an unfolded state in which the PCB is insertable into the cavity, and a folded state in which the PCB is at least partially enclosed within the cavity and the microphone is enclosed within the cavity.

Abstract: Various embodiments of a superamphiphobic filter and an ear-wearable electronic device including such filter are disclosed. The filter includes a microparticle layer formed from microparticles. The microparticle layer includes a first major surface, a second major surface, and microstructures disposed in the layer that extend from the first major surface. The filter further includes at least one acoustic passageway disposed through the layer between the first and second major surfaces, and nanoparticles disposed on the first major surface of the layer and one or more of the microstructures.

Abstract: Various embodiments of a hearing device system are disclosed. The system includes a first hearing device, a second hearing device, and a receiver operatively coupled to one or both of the first hearing device and the second hearing device. The system further includes a controller configured to provide a receiver signal to the receiver based on at least one of a first audio signal received from the first hearing device or a second audio signal received from the second hearing device, determine a first signal to noise ratio of the first audio signal, and determine a second signal to noise ratio of the second audio signal. The controller is further configured to compare the first signal to noise ratio and the second signal to noise ratio, and modify the receiver signal based on a difference between the first signal to noise ratio and the second signal to noise ratio.

Abstract: An ear-wearable device includes a receiver that produces sound into an ear canal and an inward-facing microphone determining sound pressure resulting from: the sound reproduced by the receiver into the ear canal; and acoustical noise leaking into the ear canal. A structural vibration sensor is coupled to detect at least one of body-induced vibrations and receiver-induced vibrations and produce a sensed vibration signal in response. A sound processor of the ear-wearable device is operable to determine an error signal from the inward-facing microphone and determine an active noise cancellation (ANC) signal based on the error signal. The vibration signal is used to reduce the impacts of vibrations on ANC processing within the ear-wearable device.
