摘要： A system and method for reducing baffle vibration includes balancing an inertial force generated by two or more moving diaphragms and balancing an acoustic pressure acting on a housing supporting the two or more moving diaphragms such that a net force acting on the baffle is substantially zero. The acoustic force acting on the housing may be balanced independently of the inertial force balance. In another configuration, the acoustic force acting on the housing may be balanced by a non-zero net inertial force.

摘要： A method and apparatus for detecting microphone interference includes first and second built-in microphones (111, 115) producing first and second microphone signals. A first filter bank (231) creates first high-frequency-band and first low-frequency-band signals from the first microphone signal. A second filter bank (235) creates second high-frequency-band and second low-frequency-band signals from the second microphone signal. A first measurement calculator (262) determines a high-frequency-band energy value from the first high-frequency-band signal and the second high-frequency-band signal when the first and second high-frequency-band signals' magnitudes exceeds predetermined thresholds. A second measurement calculator (266) calculates a low-frequency-band energy value from the first low-frequency-band signal and the second low-frequency-band signal when the first and second low-frequency-band signals' magnitudes exceed predetermined thresholds. A logic control block (280), coupled to the first measurement calculator and the second measurement calculator, detects microphone interference and produces an output signal (299) indicating microphone occlusion or wind noise.

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.

摘要： A thermoacoustic generator includes a housing with a thermoacoustic core supported in the housing. The core is operable to introduce acoustical power into the housing to thereby oscillate the pressure of the gas in the housing at a frequency. A piezoelectric alternator is also supported in the housing and has a face that is movable when acted on by the acoustical power. The alternator includes a portion of piezoelectric material operable to produce electrical power when acted upon by a stress. The piezoelectric material is in mechanical communication with the movable face so that movement of the face stresses the piezoelectric material. The alternator has a moving mass that serves as a substantial portion of the resonating mass inside the housing, thereby providing a pressure oscillation frequency in the housing substantially lower than a similar system with a rigid member replacing the alternator.

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.
