    摘要: Loudspeaker systems for handheld devices (2400, 2500) such as cellular telephones (100, 1400, 1600, 1900) are provided. The loudspeaker systems include at least one omnidirectional monopole loudspeaker (404, 1504, 1802, 1918, 1920) and at least one dipole loudspeaker (402, 1502, 1804, 1914, 1916). Filtering is used to compensate for differences between electric-to-acoustic signal transfer functions of the loudspeakers in order to achieve destructive interference of emitted audio in one direction and reinforcement in another direction. Various loudspeaker systems that are reconfigurable from directional mode, to omnidirectional mode are provided. Filtering is also used to add a frequency dependent phase to one signal in order to alter a direction of maximum sound pressure level. Two monopole-dipole pairs can be used to produce a stereo effect. The monopole and dipole loudspeakers can be housed in a detachable loudspeaker accessory (200).

    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: 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.
