Objective <p>To address the challenge of broadband vibration and noise control in lightweight structures, this paper proposes a novel strategy that synergistically integrates the energy focusing of Acoustic Black Holes (ABH) with the electromechanical dissipation of Piezoelectric Shunt Damping (PSD). </p> Methods <p>The proposed ABH-piezoelectric concept is implemented in a complex curved cylindrical shell structure and further extended to arrayed and hybrid configurations to enhance broadband attenuation performance. A multi-stage energy attenuation chain based on "ABH energy focusing → piezoelectric conversion → circuit dissipation" is established. The design is realized by constructing a heterogeneous cylindrical-shell core composed of piezoelectric–ABH units with complementary dynamic characteristics. Time-domain, frequency-domain, Sound Transmission Loss (STL) and Vibration Transmission Loss (TL) analyses are conducted to evaluate the performance.</p> Results <p>Firstly, compared to a uniform shell unit, a single piezoelectric-ABH unit improves the energy harvesting efficiency (electrical power level) by an average of 7.87 dB and a peak of 5.03 dB. Secondly, arranging the units into an array further enhances broadband energy dissipation, achieving a 15–20 dB increase in power level within the 1500–4000 Hz frequency band. Finally, the piezoelectric ABH cylindrical shell sandwich plate exhibits superior vibration and noise reduction performance over a traditional prismatic sandwich plate of equivalent mass in the 100–4000 Hz range</p> Conclusions <p>This study offers a new design concept for the next generation of high-performance, lightweight, intelligent vibration and noise control structures.</p>
