  • Wrist wearable apparatuses and methods with desired signal extraction
    Patent number: 11854565
    Abstract: Systems and methods are described to extract desired audio from an apparatus to be worn on a user's wrist. The apparatus includes a wrist wearable device, configured to be worn on the user's wrist. The wrist wearable device includes a first microphone. The first microphone has a first response pattern. The first microphone is coupled to the wrist wearable device. The first microphone is positioned on the wrist wearable device to receive a voice signal from a user when the wrist wearable device is on the user's wrist.

  • Head wearable acoustic system with noise canceling microphone geometry apparatuses and methods
    Patent number: 10306389
    Abstract: Systems and methods are described to extract desired audio from an apparatus that is worn on a user's head. The apparatus includes a head wearable device. A first microphone is positioned on the head wearable device to receive a voice signal from the user A first signal from the first microphone is input as a main channel to a noise cancellation unit. A second microphone is coupled to the head wearable device. A first acoustic distance between the first microphone and the user's mouth is less than a second acoustic distance between the second microphone and the user's mouth when the head wearable device is on the user's head. A second signal from the second microphone is input as a reference channel to the noise cancellation unit. A first signal-to-noise ratio of the first signal is larger than a second signal-to-noise ratio of the second signal.
