摘要： Provided is an active vibration or noise suppression system capable of converging vibration or noise more quickly.A sine wave control signal y(n) is constituted by frequency of a vibration or noise source, and an amplitude filter coefficient a(n) and a phase filter coefficient φ(n) as an adaptive filter coefficient. The sine wave control signal y(n) is expressed by a sine wave having an amplitude component and a phase component, and each of an amplitude update term Δa(n+1) and a phase update term Δφ(n+1) includes a sine wave or cosine wave term having an amplitude component and a phase component. Then, the phase component of the sine wave control signal y(n) is multiplied by a coefficient other than 1, or the phase component of the sine wave or cosine wave term of each of the amplitude update term Δa(n+1) and the phase update term Δφ(n+1) is multiplied by a coefficient other than 1. This achieves fast convergence of vibration or noise.
摘要翻译：提供了能够更快地收敛振动或噪声的主动振动或噪声抑制系统。正弦波控制信号y（n）由振动或噪声源的频率以及作为自适应滤波器系数的幅度滤波器系数a（n）和相位滤波器系数phi（n）构成。正弦波控制信号y（n）由具有振幅分量和相位分量的正弦波表示，振幅更新项Deltaa（n + 1）和相位更新项Deltaphi（n + 1）中的每一个包括具有振幅分量和相位分量的正弦波或余弦波项。然后，将正弦波控制信号y（n）的相位分量乘以除1以外的系数，或者将振幅更新项Deltaa（n + 1）和振幅更新项Deltaa（n + 1）中的每一个的正弦波或余弦波项的相位分量相位更新项Deltaphi（n + 1）乘以除1之外的系数。这实现了振动或噪声的快速收敛。

摘要： A fluid-filled vibration damping device including a second orifice passage and a third orifice passage tuned to a lower frequency than the second orifice passage, and an actuator including an output portion facing openings of the second and third orifice passages on a side of an equilibrium chamber via a flexible film. The flexible film obstructs the openings of the second and third orifice passages when the output portion comes into contact against a partition member so that the third orifice passage is blocked while the second orifice passage is substantially placed in communication owing to a center recess of the output portion permitting deformation of the flexible film. Meanwhile, the flexible film is separated from the openings of the second and third orifice passages when the output portion is separated from the partition member so that the two orifice passages are placed in communication.
摘要翻译：一种流体填充的减振装置，包括第二孔口通道和第三孔口通道，其被调节到比第二孔口通道更低的频率，以及致动器，其包括在平衡侧的面向第二和第三孔口通道的开口的输出部分室通过柔性膜。当输出部分与分隔构件接触时，柔性膜阻挡第二和第三孔口的开口，使得第三孔口通道被阻挡，同时第二孔口通道基本上由于输出的中心凹部而连通部分允许柔性膜的变形。同时，当输出部分与分隔件分离时，柔性膜与第二和第三孔口通道的开口分离，使得两个孔口通道相互连通。

摘要： A vibration damping device including a first mounting member arranged on a lower side of a second mounting member, the first and second mounting members being elastically connected by a main rubber elastic body, and an outer bracket arranged on the lower side of the second mounting member. A coupling part is constituted by engagement between a bottom edge of the second mounting member and a top edge of the outer bracket, and the second mounting member is configured to be attached to a vibration source via the outer bracket. The outer bracket is arranged in opposition to the first mounting member in an axis-perpendicular direction, and an axis-perpendicular stopper member that regulates relative displacement between the first and second mounting members in the axis-perpendicular direction is constituted by contact between the first mounting member and the outer bracket.
