IPC: B60R11/02
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To enable suppressing vibration noise independently of variation of a vibration noise source. SOLUTION: This device 4 is constituted so that a cosine wave signal and a sine wave signal synchronizing with a frequency of an engine pulse are generated from a cosine wave generator 6 and a sine wave generator 7, the generated sine wave signal is multiplied by the generated cosine signal and an adaptive notch filter coefficient W0 by a coefficient multiplier 9 in an adaptive notch filter 8 for suppressing a vibration noise, the generated sine wave signal is multiplied by an adaptive notch filer coefficient W1 by a coefficient multiplier 10, an output in which output of the coefficient multipliers 9 and 10 are added by an adder 11 is outputted to a secondary vibration noise generator 3, a secondary vibration noise is generated, and a vibration noise is canceled.  In this case, update quantity of an adaptive notch filter coefficient is changed based on a step size parameter varied based on amplitude of an output of the adaptive notch filter 8 directly before updating an adaptive notch filter coefficient, and thus, a vibration noise based on an engine pulse is suppressed.

Filed: 1987-10-19
Abstract: PURPOSE:To increase an electromechanical coupling coefficient by specifying muwhen the propagation direction of a surface acoustic wave is expressed in (lambda, mu, 90) in terms of Euler's angle representation.
