摘要： PURPOSE:To make it possible to cancel a periodical noise without generating malfunction and a delay even when a non-periodical noise is mixed with the periodical noise. CONSTITUTION:A reference signal detected by reference signal detecting means 11 is filtered by an adaptive filter 12, the filtered signal is outputted to an actuator 14 to be an electromechanical transducing means and an output from the actuator 14 is added to an input noise. An error to be an added result is converted into an electric signal by a sensor 15 and the electric signal is separated into a periodical error and a non-periodical error by a periodical signal separating means 17. A coefficient updating means 13 updates the tap coefficient of an adaptive filter by using the separated periodical error and a signal passed through a transmission characteristic compensating filter 16 based upon the algorism of an LMS or the like.

摘要： PROBLEM TO BE SOLVED: To secure a body sonic effect without the use of exclusive auxiliary speakers no sheets, etc., by superimposing the output signal of a car audio device on an actuator control signal in a prescribed condition and inputting these signals to the actuators. SOLUTION: The error detection sensors SA and SB can detect the vibrations of a car body F, caused by the residual vibration component obtained after an offset carried out between the vibrations which are caused at the body F by the operation of an engine E and the vibrations which are caused by the actuators of active mounts M1 and M2 . The mounts M1 and M2 construct at least some of plural vibration control mounts which are placed between a power unit P and the body F with front-back and right-left spaces secured among them, in order to support the unit P, including the engine E, at the front part of the body F. Then each of both mounts M1 and M2 functions to secure the elastic connection between a pair of attachment parts, via a hollow elastic supporter of hard rubber.

摘要： PURPOSE: To avoid lowering of controllability even in the case of a sudden change in speed of revolution of a rotating body at a transient time etc., and to perform a desired vibration noise control under any running conditions by setting a specific value for ratio of sampling period to vibration noise period. CONSTITUTION: A sampling period producing means produces a sampling period Ts by frequency-dividing a vibration noise period Tr so that the ratio M of the sampling period Ts to the vibration noise period Tr becomes M=1/2 (m is 2 or a larger integer, preferably, 5 or 6). Here, in the case of M=6, namely, when the ratio M of the sampling period Ts to the vibration noise period Tr is set to 1/64, 64 sampling pulse signals Ps are inputted, and every time the sampling pulse signal Ps is inputted, a corresponding sine wave signal U10 and a delayed sine wave signal U11 are successively outputted, with the input timing of the sampling pulse used as a read out pointer.

摘要： PURPOSE:To reduce the effect of disturbance, and to improve the transient characteristic of a synchronous noise by correcting a gain so that the sum of squares of an error between the waveform of the inputted synchronous noise and the output waveform of a synchronous filter. CONSTITUTION:A pulse generator 11 divides the synchronization of the inputted synchronous noise by the number N of taps of a synchronous filter 12, and generates a sampling enabling pulse, and the filter 12 successively outputs the N pieces of taps synchronously with the pulse. The output of the filter 12 is added to the noise, and a filter coefficient correcting means 13 updates the tap value of the filter 12 so that the addition error becomes small. Next, the sum of squares of the difference between the output waveform of the filter and the waveform of the input noise is searched on the assumption that each tap of the filter 12 is multiplied by a gain (g) each time the pulse generated once in one cycle of the synchronous noise from the synchronous noise generating means 14 is inputted, and a filter gain correcting means 15 decides the gain (g) so that the sum of squares becomes minimum. Thus, the transient characteristic of the synchronous noise can be improved.

摘要： PURPOSE:To improve converging speed and perform precise adaptive control with high accuracy by generating plural kinds of pulse signals corresponding to vibration-noise characteristic of each constituent part, and inputting these pulse signals directly into plural adaptive control circuits. CONSTITUTION:Timing pulse signals prepared by a dividing circuit 39 are sampled by sampling frequency prepared by a gradual doubling circuit 40, and inputted into adaptive control circuits 471-474. Control signals are converted into analog signals by a D/A converter 43, amplified by an amplifier 44 and inputted as offset signals into an adder 46 through a self-expansion type engine mount 14a and a vehicle body 45. On the other hand, a vibration-noise signal from an engine 1 is inputted into the adder 46, from which an error signal between the vibration-noise signal and the offset signal is outputted and fed back to the adaptive control circuits 471-474. Accordingly, even if the sampling frequency changes, a desired offset signal can be obtained following this change, and vibration-noise can be reduced.
