Abstract: 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.

Abstract: Example methods and systems use multiple sensors to determine whether a speaker is speaking. Audio data in an audio-channel speech band detected by a microphone can be received. Vibration data in a vibration-channel speech band representative of vibrations detected by a sensor other than the microphone can be received. The microphone and the sensor can be associated with a head-mountable device (HMD). It is determined whether the audio data is causally related to the vibration data. If the audio data and the vibration data are causally related, an indication can be generated that the audio data contains HMD-wearer speech. Causally related audio and vibration data can be used to increase accuracy of text transcription of the HMD-wearer speech. If the audio data and the vibration data are not causally related, an indication can be generated that the audio data does not contain HMD-wearer speech.

Abstract: A wearable computing device can receive, via at least one input transducer, a first audio signal associated with ambient sound from an environment of the device. The device can then process the first audio signal so as to determine a second audio signal that is out of phase with the first audio signal and effective to substantially cancel at least a portion of the first audio signal. The device may then generate a noise-cancelling audio signal based on the second audio signal, based on a third audio signal, and based on one or more wearer-specific parameters, where the third audio signal is representative of a sound to be provided by the device. The device may then cause a bone conduction transducer (BCT) to vibrate so as to provide to an ear a noise-cancelling sound effective to substantially cancel at least a portion of the ambient sound.

Abstract: Exemplary wearable computing systems may include a head-mounted display that is configured to provide indirect bone-conduction audio. For example, an exemplary head-mounted display may include at least one vibration transducer that is configured to vibrate at least a portion of the head-mounted display based on the audio signal. The vibration transducer is configured such that when the head-mounted display is worn, the vibration transducer vibrates the head-mounted display without directly vibrating a wearer. However, the head-mounted display structure vibrationally couples to a bone structure of the wearer, such that vibrations from the vibration transducer may be indirectly transferred to the wearer's bone structure.
