Vibration control remains a pivotal challenge in engineering, demanding solutions that offer wideband and low-frequency effectiveness with minimal energy. This paper introduces a hybrid vibration control method, combining semi-active piezoelectric (Piezo), and passive acoustic black hole (ABH) techniques. The semi-active approach, similar to Bang-Bang control, efficiently curtails low-frequency vibrations without precise control modes, using scant external energy. Concurrently, passive strategies exploit the ABH effect to absorb medium-high frequency waves through focused damping. The integration of Piezoelectric integrated ABH (Piezo-ABH) structures showcases the feasibility of broad-spectrum vibration dampening, with experimental outcomes revealing significant vibration reduction across 20 ∼ 2000 Hz, averaging an 8.0 dB decrease.
