摘要

•A novel origami-based acoustic metamaterial (OBAM) was designed and fabricated.•OBAM's tunable and broadband TL capacity at low frequencies was demonstrated.•OBAM's thickness is only 1/18–1/6 λ with λ being the working wavelength.•OBAM allows airflow-permeating and owns high design flexibility and programmability.
