    摘要: At least two microphones generate wideband electrical audio signals in response to incoming sound waves, and the wideband audio signals are filtered to generate low band signals and high band signals. 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, a beamformer module, and a combiner module. The microphone array has at least two pressure microphones 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 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 (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.

    摘要: A mobile station (100) that includes a processor (212) that selectively disables at least one station component to reduce electromagnetic noise generated by the station in the frequency range below 20 kHz when the mobile station is operated in the hearing aid compatible mode. The component can be, for example, a display (204), a light (206) or a wireless interface (208). The processor also can optimize characteristics of audio signals transmitted from the mobile station to the hearing aid for reproduction by the hearing aid. For instance, the processor can selectively adjust filter parameters (216) and/or a signal gain (218) applied to audio signals. A user interface (220) having a soft-key can be provided to cycle through various HAC options.
