Abstract
Transducer steering and configuration systems and methods using a local positioning system are provided. The position and/or orientation of transducers, devices, and/or objects within a physical environment may be utilized to enable steering of lobes and nulls of the transducers, to create self-assembling arrays of the transducers, and to enable monitoring and configuration of the transducers, devices, and objects through an augmented reality interface. The transducers and devices may be more optimally configured which can result in better capture of sound, better reproduction of sound, improved system performance, and increased user satisfaction.
Claims20
A system, comprising:
- a plurality of transducers comprising a microphone array;
- a local positioning system configured to determine and provide one or more of a position or an orientation of each of the plurality of transducers within a physical environment;
- and
- a processor in communication with the plurality of transducers and the local positioning system, the processor configured to:
- receive the one or more of the position or the orientation of each of the plurality of transducers from the local positioning system;
- receive one or more of a position or an orientation of a target source within the physical environment;
- determine a steering vector of one or more of a lobe or a null of at least one of the plurality of transducers, based on the one or more of the position or the orientation of each of the plurality of transducers and the one or more of the position or the orientation of the target source, by determining the steering vector of the lobe of the microphone array such that the lobe points from the microphone array away from the position of the target source;
- and
- transmit the steering vector to a beamformer to cause the beamformer to update the location of the one or more of the lobe or the null of the at least one of the plurality of transducers.

- and
- transmit the steering vector to a beamformer to cause the beamformer to update the location of the one or more of the lobe or the null of the at least one of the plurality of transducers.
