Abstract

Conical Shellular Metamaterials

In article number 2401910, Miso Kim and co-workers introduce a high-stiffness, low-density conical shellular metamaterial (CSM) to realize a piezoelectric flat panel loudspeaker with flat frequency responses. Integrating CSM into the diaphragm reduces peak-dip deviation, creating a smoother and more comfortable sound experience. This approach enhances spatial efficiency and overcomes design limitations, thereby expanding the usability of flat panel loudspeakers.
