To overcome the limitations of conventional acoustic focusing devices—which are often hindered by static focal lengths or overly complex tuning mechanisms—this research proposes a highly reconfigurable acoustic lens based on the Resch origami pattern. By leveraging the intrinsic curvature developed during the folding process, the structure's hexagonal facets function as segmented mirrors that precisely concentrate acoustic energy. Both numerical simulations and experimental validations demonstrate that the device’s focal length can be dynamically tuned simply by adjusting the folding ratio, offering a simplified yet versatile platform for adaptive acoustic manipulation.
