Beamforming Microphone Array with Support for Interior Design Elements

摘要

Embodiments of the present disclosure include an apparatus (210, 230, 240, 250) configured to perform beamforming on multiple audio input signals. The apparatus (210, 230, 240, 250) includes one or more illumination devices (222, 232, 242, 252) and a beamforming microphone system (116) integrated with the one or more illumination devices. The beamforming microphone system (116) includes a first plurality of microphones (302, 502) configured to resolve first audio input signals within a first frequency range. The beamforming microphone system (116) also includes at least one microphone (504) configured to resolve second audio input signals within a second frequency range. A lowest frequency in the first frequency range is greater than a lowest frequency in the second frequency range.

1. An apparatus for beamforming of audio input signals, comprising:
one or more illumination devices; and a beamforming microphone system integrated with the one or more illumination devices, wherein the beamforming microphone system comprises:
a plurality of first microphones resolving first audio input signals within a first frequency range;at least one second microphone resolving second audio input signals within a second frequency range, the first frequency range having a lowest frequency greater than a lowest frequency of the second frequency range;a noise gating module generating a restricted second audio input signals bound within a frequency range between the lowest frequency of the first audio input signals and the lowest frequency of the second audio input signals, or between a highest frequency of the first audio input signals and a highest frequency of the second audio input signals, the noise gating module being coupled to the plurality of first microphones and to the at least one second microphone; andan augmented beamforming module coupled to the noise gating module, wherein the augmented beamforming module is configured to:
receive the restricted second audio input signals and the first audio input signals; andperform beamforming on the received first audio input signal and the restricted second audio input signals within a bandpass frequency range, the bandpass frequency range being a combination of the first frequency range and a restricted second frequency range.
