摘要： A user control with haptical feedback on a 3 -dimensional touch surface is provided. The control includes a 3 -dimensional touch surface to be touched by a user with an electrode structure arranged at least partly on it. The electrode structure is configured to provide haptical feedback to the user based on electro-adhesion between the user and the control. The user control with haptical feedback on a 3 -dimensional touch surface is electrically contacted using a contacting surface, on which an anisotropic conducting film layer and a flexible printed circuit are arranged.

摘要： A noise suppression method includes transforming a time-domain input signal into an input spectrum that is the spectrum of the input signal, the input signal comprising speech components and noise components, and the input spectrum comprising a speech spectrum that is the spectrum of the speech components and a noise spectrum that is the spectrum of the noise components, smoothing magnitudes of the input spectrum to provide a smoothed-magnitude input spectrum, and estimating basic suppression filter coefficients from the input spectrum and the smoothed input spectrum. The method further includes determining noise suppression filter coefficients from the estimated basic suppression filter coefficients and a spectral correlation factor, the spectral correlation factor indicating whether speech is present in the input signal or not, filtering the input spectrum based on the noise suppression filter coefficients to generate an output spectrum; and transforming the output spectrum into a time-domain output signal. The spectral correlation factor is determined from a scaling factor and the smoothed input spectrum, the scaling factor being determined iteratively starting from a start correlation factor. An example noise suppression structure includes a processor and a memory, the memory storing instructions of a program and the processor configured to execute the instructions of the program, carrying out the above-described method. An example computer program product includes instructions which, when the program is executed by a computer, cause the computer to carry out the above-described method.

摘要： A loudspeaker arrangement comprises a mid-range loudspeaker (20) arranged in a dashboard of a vehicle (10), a first tweeter (22) arranged adjacent to the mid-range loudspeaker (20) in the dashboard of the vehicle (10), and a second tweeter (24) arranged adjacent to the mid-range loudspeaker (20) in the dashboard of the vehicle (10). The mid-range loudspeaker (20) is arranged between the first tweeter (22) and the second tweeter (24). The mid-range loudspeaker (20) is a non-directional loudspeaker that radiates sound towards a driver's seat (102) and towards a passenger seat (104) in equal parts. The first tweeter (22) is a directional loudspeaker that radiates sound primarily towards the passenger seat (104), and the second tweeter (24) is a directional loudspeaker that radiates sound primarily towards the driver's seat (102).

摘要： Automatic noise control includes evaluating an amplitude of an acceleration acting on an acceleration sensor and generating a reference signal representative of the amplitude of the acceleration, the acceleration being representative of unwanted noise sound generated by a noise source, filtering the reference signal with a noise control transfer function to generate an anti-noise signal, and converting with a loudspeaker the anti-noise signal into anti-noise sound. Automatic noise control further includes receiving with a microphone the noise sound after being transferred via a primary path according to a primary path transfer function from the noise source to the microphone and the anti-noise sound after being transferred via a secondary path according to a secondary path transfer function from the loudspeaker to the microphone and converting with the microphone a sum of the received noise sound and the received anti-noise sound into an error signal. Automatic noise control further includes controlling the noise control transfer function based on the error signal from the microphone and the filtered or unfiltered reference signal from the acceleration sensor so that the anti-noise sound after being transferred via the secondary path is the inverse of the noise sound after being transferred via a primary path, and applying via the filter controller to the noise control transfer function of the noise control filter a leakage based on the error signal from the microphone and the filtered or unfiltered reference signal from the acceleration sensor.

摘要： Canceling acoustic echoes includes picking up with a microphone sound generated by a sound source and transferred from the sound source to the microphone via an unknown transfer path having an unknown transfer function, and providing an electrical microphone signal therefrom. It further includes approximating the unknown transfer function with an estimated transfer function of an adaptive filter and filtering an electrical signal representative of the sound generated by the sound source with the estimated transfer function to provide an estimated signal therefrom, the adaptive filter having an adaptive adaptation step size. It further includes filtering a difference signal, which is the difference between the microphone signal and the estimated signal, with a post filter transfer function of an adaptive post filter. The post filter transfer function is the difference between one and the adaptive adaptation step size, and the adaptive post filter is configured to have a minimum damping, the minimum damping being limited to a minimum threshold.
