发明名称 MOTION DETECTION OF AUDIO SOURCES TO FACILITATE REPRODUCTION OF SPATIAL AUDIO SPACES
摘要 Embodiments of the invention relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, and wearable/mobile computing devices configured to facilitate production and/or reproduction of spatial audio and/or one or more audio spaces. More specifically, disclosed are systems, components and methods to acoustically determine displacements of audios sources (or portions thereof), such as a subset of speaking users, for providing audio spaces and spatial sound field reproduction, for example, for a remote listener. In one embodiment, a media device includes transducers to emit audible acoustic signals into a region including one or more audio sources, acoustic probe transducers configured to emit ultrasonic signals and acoustic sensors configured to sense received ultrasonic signals reflected from an audio source. A controller can determine a displacement of the audio source. Examples of displacement include locomotion, gesture-related motion and orientation changes.

主权项 1. A method comprising: generating unique ultrasonic signals, at least a unique ultrasonic signal being generated for emission from corresponding an acoustic probe transducer; emitting the unique ultrasonic signal in a direction associated with the acoustic probe transducer;sensing reflected ultrasonic signals from one or more surfaces, a subset of surfaces being associated with an object;identifying a position of the object relative to the point in space as a function of characteristics of the reflected ultrasonic signals;determining a displacement of at least a portion of the object;identifying an action responsive to the displacement; andperforming the action to modify operation of an audio system.
