PROBLEM TO BE SOLVED: To provide a new structural active vibration control equipment of a fluid filled-system by which the active vibration control effectiveness by the stimulus of a elastic stimulative plate in a high frequency region is improved by increasing the stimulative amplitude of the elastic stimulative plate in a low frequenct region, while fully maintaining the active vibration control effectiveness to a great amplitude vibration in the low frequent region. SOLUTION: The elastic stimulative plate 38 with low spring rigidity and the elastic stimulative plate 40 with high spring rigidity are formed independently, and the respective elastic stimulative plates 38, 40 are made to elastically stimulate in the condition corresponding to the size of each spring rigidity by which the fluctuation by common air pressure is caused to affect those respective elastic stimulative plates 38, 40 through an application air chambers 84, 86, thereby the pressure in a main liquid chamber 58 of which the wall is constituted of the elastic stimulative plates 38, 40 is advantageously controlled even in a wide frequenct region or a different frequent region and is made to exert the active vibration control effectiveness. |
