In certain implementations, the in-ear audio devices include an eartip with a body having first and second ends, an inner wall extending between the first and second ends defining a hollow passage to conduct acoustic energy, and a deformable outer wall connected to the inner wall of the body at the first end and tapering away from the inner wall toward the second end, where the deformable outer wall is functionally graded from the first end to the second end to comply with an entrance of an ear canal of a user. In additional implementations, the eartip includes a retaining structure, and at least one of the inner wall or the outer wall of the body, or the retaining structure, has an integral electronic component and/or an electronic component signal trace.

Abstract: A wind noise reduction system including a beamformer, a comparator, and a voice mixer is provided. The beamformer may be an MVDR beamformer, and generates a beamformed signal based on a first microphone signal and a second microphone signal. The comparator generates a comparison signal based on the beamformed signal and a wind microphone signal. The comparison signal may be further based on a beamformed energy level of the beamformed signal and a wind energy level of the wind microphone signal. The voice mixer generates an output voice signal based on the beamformed signal, the wind microphone signal, and the comparison signal. The wind noise reduction system may further include a wind microphone corresponding to the wind microphone signal. The wind microphone may be arranged on a portion of a wearable audio device configured to be seated in a concha of a wearer.

Abstract: An audio device with a body configured to be worn on or abutting an outer ear of a user, wherein the body is configured to contact at least one of the outer ear and the portion of the head that abuts the outer ear, at two separate spaced contact locations, and wherein the body is compliant at a body portion that defines one of the contact locations. The device also has an acoustic module carried by the body and configured to locate a sound-emitting opening anteriorly of and proximate the user's ear canal opening when the body is worn on or abutting the ear of the user.

Abstract: A system and method for managing simultaneous data streams from multiple sources is provided. At least one paired audio device within the system, is a managing device and coordinates the audio playback presented in each paired audio device. In this way, each device can produce an audio playback associated with different streams simultaneously. In some examples, the managing device is one of the two devices or a peripheral device, e.g., a smartphone. In some examples, each data stream contains data used to generate a priority level for each data stream. The managing device can allow a data stream having a higher priority level or the data stream with a detected change to “barge-in” causing the playbacks of each device to be associated with a different data stream. Additionally, each device is capable of assuming the role of “stream scanner” to prevent uneven power consumption between the devices within the system.

Abstract: An active noise reduction earbud includes a housing and a first feedforward microphone disposed in the housing. A first sound inlet opening extends through the housing and is configured to conduct external sound to the first feedforward microphone. The first sound inlet opening is configured to sit within a concha cavum of a user's ear and faces toward an auricle of the user's ear when the earbud is worn.

Abstract: An audio system that is configured to convert a plurality of audio input channels to object-based audio, and a related computer program product. Correlation between input channels and energy balance between the input channels are determined. The determined correlation and energy balance are mapped to output three-dimensional spatial locations.

Abstract: An audio system including a wearable audio device having a sensor to determine a first motion of the first wearable device from a first orientation to a second orientation, a first peripheral device, a first input arranged on, in, or in communication with the wearable audio device or the first peripheral device, and circuitry connected to the wearable audio device or the first peripheral device. The circuitry is arranged to: receive the first input while the first wearable audio device is in the first orientation; receive the first input while the first wearable audio device is moved via the first motion to the second orientation; determine that the first input has been released during or after the first motion; and, adjust a setting of the wearable audio device or the first peripheral device based at least in part on the first motion from the first orientation to the second orientation.

Abstract: A voice capture system including a first and second voice beamformer, a voice mixer, a voice rejected noise beamformer, a noise beamformer adjustor, a jammer suppressor, and a speech enhancer is provided. The first and second voice beamformer and the voice mixer generate a voice enhanced reference signal based on a first and second frequency domain microphone signal. The voice rejected noise beamformer includes filter weights and generates a noise reference signal based on the first and second frequency domain microphone signal. The noise beamformer adjustor adjusts the one or more filter weights of the voice rejected noise beamformer to account for fit variation. The jammer suppressor generates a jammer suppressed signal based on the voice enhanced reference signal and the noise reference signal. The speech enhancer dynamically generates an output voice signal by applying a dynamic noise suppression signal to each frequency bin of the jammer suppressed signal.

Abstract: Systems and methods of providing audio through or near a headrest are provided. A headrest includes an adjustable surface positioned to be proximate an occupants head when in use and an acoustic opening is configured to emit acoustic energy from an acoustic transducer in a range of directions in which an ear of the occupant is expected to occupy. The position of the adjustable surface gives some indication of the location of the occupants ear, and various audio signal (driver signal) properties may be adjusted based upon the position of the adjustable surface.

Abstract: A method for detecting and mitigating parasitic oscillation in a headphone equipped with an active noise reduction (ANR) system. A fundamental frequency of a microphone signal is determined from a microphone of the ANR system and an amplitude of the determined fundamental frequency is compared to a threshold level to determine parasitic oscillation. If parasitic oscillation is determined, then the microphone signal is altered to mitigate the parasitic oscillation.
