  • Patent number: 11302342
    Abstract: A system configured to detect a tap event on a surface of a device using microphone audio data and motion data. Instead of using a physical sensor to detect the tap event, the device detects a tap event based on a power level difference between two or more microphones. When a power ratio exceeds a threshold, the device may detect a tap event and perform an action, such as delaying or ending an alarm. To reduce false positives caused by wind or loud noises close to the microphones, the device may confirm a tap event using motion data that indicates actual movement of the device. In some examples, the device may detect the tap event using a neural network processing the microphone data and the motion data. In addition, the device may embed the motion data within the microphone data using unused bits of the microphone data.

  • Patent number: 11107488
    Abstract: A system configured to perform echo cancellation using a reduced number of reference signals. The system may perform multi-channel acoustic echo cancellation (MCAEC) processing on a first portion of a microphone audio signal that corresponds to early reflections and may perform single-channel acoustic echo cancellation (AEC) processing on a second portion of the microphone audio signal that corresponds to late reverberations. For example, the system may use MCAEC processing on a plurality of reference audio signals to generate a first echo estimate signal and may subtract the first echo estimate signal from the microphone audio signal to generate a residual audio signal. The system may delay the first echo estimate signal, perform the AEC processing to generate a second echo estimate signal, and subtract the second echo estimate signal from the residual audio signal to generate an output audio signal. This reduces an overall complexity associated with performing echo cancellation.

  • Patent number: 11019441
    Abstract: A position sensor may include a resonator attachable to a first object, and an antenna attachable to a second object and driven at a resonant frequency of the resonator. A change in a position of the first object relative to the second object may be sensed as a change in a power of the antenna when the antenna is driven at the resonant frequency of the resonator. The first object may be a former of a speaker, and a voice coil of the speaker may be positioned on the former together with the position sensor. In operation, the antenna may output a position signal to an external system of electronics, indicating a position of the voice coil. The external system of electronics may perform feedback processing to compensate for nonlinearities in the voice coil's position when the voice coil is used to drive a diaphragm of the speaker.
