Abstract
An audio device comprising, an interface, one or more first output transducers, one or more input transducers, and a processor. The audio device is configured to emit a first ultrasound signal, receive a first reflection indicative of the first ultrasound signal, process the first reflection to determine movement, and in response to movement being determined, adjust one or more audio processing parameters of the audio device.
Claims12
An audio device comprising, an interface, one or more first output transducers, one or more input transducers, and a processor, wherein the audio device is configured to:
- emit by the one or more first output transducers a first ultrasound signal into a first region surrounding the audio device,
- receive a first reflection indicative of the first ultrasound signal via the one or more input transducers,
- process by the processor the first reflection to determine first movement of a first object within the first region, and
- in response to first movement being determined, adjust by the processor one or more audio processing parameters of the audio device wherein to process the first reflection to determine first movement of the first object within the first region comprises to determine a center shift based on a predetermined center frequency of the first ultrasound signal, and
- wherein to process the first reflection to determine first movement of the first object within the first region comprises to compare the center shift to a higher movement threshold, and wherein if the center shift exceeds the higher movement threshold determine no movement of the first object within the first region.
