ELECTRONIC APPARATUS FOR GENERATING BEAMFORMED AUDIO SIGNALS WITH STEERABLE NULLS |
摘要 |
<p>An electronic apparatus is provided having a front side and a rear side oriented in opposite directions along a first axis, and a right-side and a left-side oriented in opposite directions along a second axis that is perpendicular to the first axis. A null control signal is generated based on an imaging signal. A first microphone located near the right-side of an electronic apparatus generates a first signal and a second microphone located near the left-side of the electronic apparatus generates a second signal. The first and second signals are processed, based on the null control signal, to generate a right beamformed audio signal having a first directional pattern having at least one first null, and a left beamformed audio signal having a second directional pattern having at least one second null. A first angular location (alpha) of the at least one first null and a second angular location (beta) of the at least one second null are steered based on the null control signal.</p> |
