摘要： A portable audio device, which includes active noise cancellation circuitry, a hearing aid compliant magnetic radiator, and a speaker/earpiece, is surrounded by ambient acoustic noise. The active noise cancellation circuitry provides an anti-noise signal at an input of the speaker to control/reduce the ambient acoustic noise outside of the device. In addition, the active noise cancellation circuitry provides an inverse anti-noise signal to an input of the magnetic radiator. The magnetic fields produced by the speaker driven by the anti-noise signal and the magnetic radiator driven by the inverse anti-noise signal cancel each other out through phase cancellation such that a hearing aid using a telecoil coupled to the audio device does not produce significant audio waves based on either of these signals. Other embodiments are also described.

摘要： 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.

摘要： A power savings mode for data updates is provided. The power savings mode prevents data updates to occur while a screen of a portable electronic device is turned off and the device is in a sleep state. The power savings mode waits until the screen is turned on and the portable electronic device is in a wake state before allowing applications and widgets to update data from network repositories. By preventing applications and widgets from updating data while the portable electronic device is in a sleep state, the power savings mode conserves battery life and network bandwidth by limiting possibly unnecessary data transmissions.

摘要： A portable electronic device that provides compact configurations for audio elements are disclosed. The audio elements can be drivers (e.g., speakers) or receivers (e.g., microphones). In one embodiment, an audio element can be mounted on or coupled to an intermediate structure (e.g., a flexible electrical substrate) having an opening therein to allow audio sound to pass there through. In another embodiment, an audio chamber can be formed to assist in directing audio sound between an opening an outer housing and a flexible electronic substrate to which the audio element is mounted or coupled thereto. In still another embodiment, a barrier, such as a mesh barrier, can be provided in an opening of an outer housing so that undesired foreign substances can be blocked from further entry into the opening in the outer housing.
