| 摘要 |
A vibration control device 1 in accordance with the present invention is provided with a liquid lever mechanism 4 which has an action member 5, a liquid chamber 6 and a driving plate 7, and is used for enlarging a displacement, a piezo-actuator 2 which can be displaced in a direction so as to change the volume of the liquid chamber 6, and a rubber vibration isolator 3 which is placed between the liquid lever mechanism 4 and the piezo-actuator 2 in series therewith. This vibration control device 1 has a low natural frequency so that it has a superior passive vibration-blocking performance at high-frequency bands, while maintaining a superior active vibration-blocking performance at low-frequency bands, and also makes it possible to achieve a small size.
