We report the realization of acoustic energy harvesting for low-frequency sound in a subwavelength system consisting of eight multiple-cavity units. This exotic energy harvesting phenomenon arises from a compound monopole Mie resonance (MMR) induced by mutual coupling between the system structure and the MMR of each unit. More importantly, the center intensity can reach about 9000 Pa2 with the parameter r/r 0 of 0.73, providing the feasibility for realizing energy harvesting in a low-energy environment. The proposed system has rich compound Mie resonances, high energy harvesting, and strong robustness, which provides diverse routes to design novel acoustic devices with versatile applications.
