Abstract: A device includes a microphone array fixed to the device. A signal processor produces an audio output using audio beamforming with input from the microphone array. The signal processor aims the beamforming in a selected direction. An orientation sensor—such as a compass, an accelerometer, or an inertial sensor—is coupled to the signal processor. The orientation sensor detects a change in the orientation of the microphone array and provides an orientation signal to the signal processor for adjusting the aim of the beamforming to maintain the selected direction. The device may include a camera that captures an image. An image processor may identify an audio source in the image and provide a signal adjusting the selected direction to follow the audio source. The image processor may receive the orientation signal and adjust the image for changes in the orientation of the camera before tracking movement of the audio source.

Abstract: A system detects the repositioning of an earphone that is worn by a user, and changes an operation mode of a host coupled to the earphone. Within the earphone is a pressure transducer that detects a pressure change caused by the repositioning of the earphone. A signaling mechanism sends a repositioning detection signal to the host in response to a signal from the pressure transducer indicating the detection of the pressure change.
