Title:
SPATIAL IMAGING ON AUDIO PLAYBACK DEVICES
Document Type and Number:
WIPO Patent Application WO/2024/054834
Kind Code:
A3
Abstract:
Example techniques relate to stereo imaging with audio playback devices. Example playback devices described herein may include multiple speakers, such as a forward-firing audio transducer and side-firing audio transducers. Using example techniques, such playback devices may play stereo content partially directly and partially as a dipole, which may enhance (e.g., widen) a stereo image formed by the transducers. Yet further, such techniques may be combined with steering techniques to direct output of the transducers away from obstructions that may be present in proximity to the audio playback devices.
