A handheld image stabilization device or an image capture device includes a housing, a motor, a microphone, and a dampener. The housing includes a first port. The motor is attached to the housing. The microphone detects audio waves via the first port and vibration noise of the motor via the housing. The audio waves may include acoustic noise from the motor. The dampener is coupled to the housing. The dampener reduces the acoustic noise from the motor and the vibration noise from the motor.

Audio enhancements in motor-driven devices

The present disclosure relates to processing a plurality of audio signals. A device receives the plurality of audio signals in the frequency domain and determining an overall attenuation multiplier based on the plurality of audio signals and an overall lookup table that relates decibel values to different overall attenuation multipliers. The device determines an attenuation vector comprising a plurality of bin-specific attenuation multipliers, each bin-specific attenuation multiplier respectively corresponding to a different frequency bin of the plurality of frequency bins. The device scales each bin-specific attenuation value in the attenuation vector with the overall attenuation multiplier, and edits each of the audio signals based on the scaled bin-specific attenuation values in the attenuation vector.

Multi-band noise gate

An image capture device and a handheld image stabilization device may each include a housing, a motor assembly, a microphone, a dampener, or any combination thereof. The housing may include a first port. The motor assembly may be attached to the housing. The motor assembly may include a plurality of motors. The microphone may be configured to detect audio waves via the first port, vibration noise of the plurality of motors via the housing, or both. The audio waves may include acoustic noise from the plurality of motors. The dampener may be coupled to the housing. The dampener may be configured to reduce the acoustic noise from the plurality of motors, the vibration noise from the plurality of motors, or both.

Protected microphone systems may include one or more dampeners, one or more cavities, or a combination thereof to minimize the vibration sensitivity of a microphone of the protected microphone systems. The dampeners, when present, may be constructed of a foam material or a thin metal material.

Systems and methods for minimizing vibration sensitivity for protected microphones

A method for detecting wind using a microphone and a speaker of an electronic device. The method obtains a microphone signal produced by the microphone. The method obtains a speaker input signal produced by the speaker that is emulating a microphone capturing ambient sound in an environment through the speaker. The method determines a coherence between the microphone signal and the speaker input signal and determines whether the coherence is below a coherence intensity threshold. In response to determining that the coherence is below the coherence intensity threshold, the method determines a presence of wind in the environment.

Speaker emulation of a microphone for wind detection

The present disclosure relates to processing a plurality of audio signals. The method includes receiving the plurality of audio signals in the frequency domain and determining an overall attenuation multiplier based on the plurality of audio signals and an overall lookup table that relates decibel values to different overall attenuation multipliers. The method further includes determining an attenuation vector comprising a plurality of bin-specific attenuation multipliers, each bin-specific attenuation multiplier respectively corresponding to a different frequency bin of the plurality of frequency bins. The method further includes scaling each bin-specific attenuation value in the attenuation vector with the overall attenuation multiplier, and editing each of the audio signals based on the scaled bin-specific attenuation values in the attenuation vector.

Protected microphone systems may include one or more dampeners, one or more protective layers, or a combination thereof to minimize the vibration sensitivity of a microphone of the protected microphone systems. The dampeners, when present, may be constructed of a foam material or a thin metal material. The protective layer may be a membrane, a mesh, or any suitable material. The protective layer may be air permeable or non-air permeable.
