Abstract: Various implementations include miniature loudspeaker drivers. In some aspects, an electro-acoustic driver includes: a cone having a surface area configured to radiate acoustic energy; a suspension coupled to the cone; and a support structure coupled to the suspension and having an outer linear dimension in a plane of the cone of approximately 6.0 millimeters (mm) or less, wherein the surface area of the cone is at least 49% of an overall cross-sectional area of the electro-acoustic driver in the plane of the cone.

Abstract: Various aspects include a wearable audio device having active noise reduction (ANR). In some cases, a method for processing audio signals includes receiving a noise reduction signal configured to modify an audio signal and generate a noise reduced audio signal, the noise reduction signal having a nominal loop gain; and generating an adjusted noise reduction signal in response to a detected adverse low frequency event, the adjusted noise reduction signal having a modulated loop gain configured to reduce artifacts in the noise reduced audio signal.

Abstract: The present disclosure provides hearing assistance devices and methods of generating a resonance within hearing assistance devices that use moving coil drivers, e.g., electro-dynamic coil drivers. As small moving coil drivers are typically inefficient within the voice band of frequencies, e.g., above 1 kHz, the hearing assistance devices described herein utilize the resonance of a mass within the hearing assistance device and a compliance of air within the housing of the hearing assistance device or within portions of the acoustic driver housing to aid in amplification of select frequencies within the voice band of human speech, e.g., between 2.5 kHz and 6 kHz. By using the assistance of the resonance created, the moving coil driver utilized does not need to operate as efficiently within the range of resonance frequencies.

Abstract: An earphone includes an earphone assembly and first and second electro-acoustic transducers. The earphone assembly includes an earphone body with an inner surface, an acoustic opening and a cavity defined inside the body by the inner surface and the acoustic opening. The earphone body further includes an acoustic impedance branch, such as a waveguide, that reduces a magnitude of a resonance at a first resonance frequency for an occluded ear canal defined by the cavity of the earphone assembly and an ear canal of a user when the earphone is at least partially inserted into the ear canal. The first electro-acoustic transducer is disposed at the inner surface of the earphone body and is configured to generate a first acoustic signal. The second electro-acoustic transducer is disposed along a length of the acoustic impedance branch and is configured to generate a second acoustic signal.

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.
