摘要： A vibration control system comprises at least one original vibration detecting means (7) located on or close to each of at least one vibration source (2) for detecting an original vibration or noise from the vibration source, at least one controlled vibration applying actuator (6) provided on an acoustic radiator (5) which is vibrated by the original vibration or noise, and controlling means for receiving a signal from the original vibration detecting means and outputting a control signal to the controlled vibration applying actuator, the controlling means including a digital filter (8) which produces a control signal for actuating the vibration applying actuator (6) so as to generate a controlled vibration wave having an inverse waveform which is of an opposite sign to the original vibration, thereby offsetting the original vibration with the controlled vibration to reduce the original vibration of the acoustic radiator and effectively isolate noise of a random vibration.

摘要： An adaptive-type vibration control apparatus for actively controlling vibration of an object (3) mounted on a movable base member (1,210) with vibration-isolating means therebetween. The apparatus includes a vibration sensor (13) secured to the object (3) for detecting vibration thereof, an actuator (12) secured to the object (3) for applying an inverse vibration thereto, and a digital filter (8) with an input (R) connected to the vibration sensor (13) and an output (S) connected to the actuator (12). The digital filter (8) is adapted to generate an output signal for controlling the actuator such that the vibration of the object (3) is at least suppressed by the inverse vibration applied to the object by the actuator (12). The vibration is actively controlled and reduced without being affected by resonance peak frequencies, particularly when the object (3) is applied with vibration over a wide frequency range, or with vibration of a random or periodic nature.
