基于磁弹性声学超材料的点缺陷和压电效应，研究了带隙和能量收集的智能控制。通过有限元方法得到的数值结果表明，频带结构和频率范围的声学能量收集可以调制显着的外加磁场，导致宽带BG和提高机电能量转换效率。该结构为工程领域可调谐隔声体和宽分布能量采集器的设计提供了新的途径。
The present study investigated the intelligent control of both band gaps (BGs) and energy harvesting based on the point defect of magneto-elastic acoustic metamaterial and piezoelectric effect. The numerical results obtained by the finite element method indicate that band structures and frequency range of acoustic energy harvesting can be modulated significantly by an applied magnetic field, which leads to broadband BGs and promotes the electromechanical energy conversion efficiency. Consequently, the proposed structure can provide new avenues for designing of both tunable acoustic insulator and a broad-distributed energy harvester in engineering fields.
