    摘要： An electronic apparatus is provided that has a rear-side and a front-side, a first microphone that generates a first signal, and a second microphone that generates a second signal. An automated balance controller generates a balancing signal based on an imaging signal. A processor processes the first and second signals to generate at least one beamformed audio signal, where an audio level difference between a front-side gain and a rear-side gain of the beamformed audio signal is controlled during processing based on the balancing signal.

    摘要： At least two microphones (330, 370) generate wideband electrical audio signals in response to incoming sound waves, and the wideband audio signals are filtered (422, 428, 442, 448) to generate low band signals (423, 443) and high band signals (429, 449). From the low band signals, low band beamformed signals are generated, and the low band beamformed signals are combined with the high band signals to generate modified wideband audio signals. In one implementation, an electronic apparatus is provided that includes a microphone array, a crossover (450), a beamformer module (470), and a combiner module (480). The microphone array has at least two pressure microphones (330, 370) that generate wideband electrical audio signals in response to incoming sound waves. The crossover generates low band signals and high band signals from the wideband electrical audio signals. The beamformer module generates low band beamformed signals from the low band signals. The combiner module combines the high band signals and the low band beamformed signals to generate modified wideband audio signals.

    摘要： An electronic apparatus (100) 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 (565) is generated based on an imaging signal (585). A first microphone (530) located near the right-side of an electronic apparatus generates a first signal, and a second microphone (520) 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 (552) having a first directional pattern having at least one first null, and a left beamformed audio signal (554) having a second directional pattern having at least one second null. A first angular location (α) of the at least one first null and a second angular location (β) of the at least one second null are steered based on the null control signal.
