摘要： Disclosed are systems, devices, and methods for minimizing mechanical-vibration-induced noise in audio signals. In one aspect, a microphone is disclosed that includes a first backplate, a first diaphragm, a second backplate, and a second diaphragm. The first diaphragm moves relative to the first backplate in response to acoustic pressure waves in an environment and mechanical vibrations of the microphone, thereby causing a first capacitance change between the first diaphragm and the first backplate. The second diaphragm is substantially acoustically isolated from the acoustic pressure waves, and moves relative to the second backplate in response to the mechanical vibrations of the microphone, thereby causing a second capacitance change between the second diaphragm and the second backplate. The microphone further includes or is communicatively coupled to an integrated circuit configured to generate an acoustic signal based on the first capacitance and the second capacitance.

摘要： The present application describes bone conduction microphone (BCM) systems and applications thereof. An example apparatus includes: (a) an enclosing structure having a cavity therein, wherein a first portion of the enclosing structure is formed by an elastic material, and wherein the elastic material is moveable to transfer vibration from an exterior source to gas within the cavity; and (b) a microphone coupled to the enclosing structure and located within the gas-filled cavity, wherein gas in the cavity separates the microphone from the first portion of the enclosing structure, such that the vibration transferred from the exterior source to the gas in the cavity is detectable by the microphone.

摘要： A wearable audio component includes a first cable and an audio source in electrical communication with the first cable. A housing defines an interior and an exterior, the audio source being contained within the interior thereof. The exterior includes an ear engaging surface, an outer surface, and a peripheral surface extending between the front and outer surfaces. The peripheral surface includes a channel open along a length to surrounding portions of the peripheral surface and having a depth to extend partially between the front and outer surfaces. A portion of the channel is covered by a bridge member that defines an aperture between and open to adjacent portions of the channel. The cable is connected with the housing at a first location disposed within the channel remote from the bridge member and is captured in so as to extend through the aperture in a slidable engagement therewith.

摘要： The present disclosure relates to managing audio signals within a user's perceptible audio environment or soundstage. That is, a computing device may provide audio signals with a particular apparent source location within a user's soundstage. Initially, a first audio signal may be spatially processed so as to be perceivable in a first soundstage zone. In response to determining a high priority notification, the apparent source location of the first audio signal may be moved to a second soundstage zone and an audio signal associated with the notification may be spatially processed so as to be perceivable in the first soundstage zone. In response to determining user speech, the apparent source location of the first audio signal may be moved to a different soundstage zone.
