摘要： An active road-noise control system and method include using a sensor arrangement to generate a first sense signal representative of at least one acceleration, motion and/or vibration that occurs at a first position on a vehicle body and a second sense signal representative of sound that occurs at a second position within the vehicle body; they also provide a noise-reducing signal by processing the sense signals according to a first or a second mode of operation. They include the generation of noise-reducing sound within the vehicle body at the second position from the noise reducing signal and the operational state of the sensor arrangement; the first sense signal and the second sense signal are processed in the first mode when the sensor arrangement is in a proper operational state and in the second mode when a malfunction of the sensor arrangement has been detected.

摘要： The audio amplifier includes a variable gain amplifier receiving the input audio signal and providing the output signal, whereby the output signal corresponds to the input signal amplified by a limiter gain. The audio amplifier further includes a limiter gain calculation unit, thus the input signal is amplified by the limiter gain. A control unit receives a signal representative of the input signal and is configured to estimate, based on a mathematical model, the input current or the total output current of the audio amplifier thus providing an estimated current signal corresponding to (and resulting from) the output signal, whereby the limiter gain calculation unit is configured to calculate, dependent on the estimation, the limiter gain such that the actual input current or the total output current of the audio amplifier does not exceed a threshold current value.

摘要： An electroactive loudspeaker includes a conductive carrier plate comprising a first main surface and a second main surface, the first main surface and the second main surface being disposed on opposite sides of the carrier plate. The electroactive loudspeaker further includes an electroactive polymer layer comprising a first main surface and a second main surface. An electrically conductive electrode layer is attached to the second main surface of the electroactive polymer layer. The first surface of the carrier plate has an area and the first surface of the electroactive polymer layer has an area, the area of the first surface of the carrier plate being larger than the area of the first surface of the electroactive polymer layer. The first main surface of the electroactive polymer layer overlaps in its entire area with the first main surface of the carrier plate.

摘要： An example headphone arrangement includes at least one earphone. The at least one earphone includes a sealed housing having an aperture and a tube with a longitudinal axis. The tube is curved along its longitudinal axis to form a closed or open ring configured to totally or partly surround an ear of a user. A speaker is mounted to the housing at the aperture so that the housing in connection with the speaker encloses a closed acoustic volume.

摘要： Active noise reduction systems and methods for a helmet with a rigid shell that spatially divides a shell interior from a shell ambiance include receiving at least one desired-sound signal representative of at least one desired sound pattern occurring in the shell ambience, and generating, based on the at least one desired-sound signal, anti-sound that is configured to interact with internal sound occurring in the shell interior through superposition. The internal sound includes first internal sound components and second internal sound components, the first internal sound components not corresponding to the at least one desired sound pattern and the second internal sound components corresponding to the at least one desired sound pattern. The anti-sound is further configured to attenuate the first internal sound components, and to amplify, not attenuate, or attenuate to a lesser degree than the first internal sound components the second internal sound components.

摘要： An example active road noise control includes generating with a sensor arrangement a primary sense signal representative of at least one of accelerations, motions and vibrations that occur at a first position, and providing a noise reducing signal by processing the primary sense signal according to an adaptive mode of operation or a non-adaptive mode of operation. It further includes generating within the vehicle body noise reducing sound at the second position from the noise reducing signal, evaluating the primary sense signal and controlling the processing of the primary sense signal so that the primary sense signal is processed in the adaptive mode of operation when the magnitude of the primary sense signal undercuts a first threshold and in the non-adaptive mode of operation when the magnitude of the primary sense signal exceeds a second threshold, the first threshold being equal to or smaller than the second threshold.
