Lower-frequency band gaps are favored by the fluid-structure interaction of two-phase scatterer locally resonant metamaterials. The vibration-damping capacity is enhanced by increasing the solid-liquid contact rate. The obtained results provide a simple passive active control design scheme for resisting the vibration noise of fluid-structure interaction structures in high-end equipment.
