The cover image is Figures 10a and 11a and b, of “A reduced-order-model-based equivalent circuit for piezoelectric micro-electro-mechanical-system loudspeakers modeling,” by C. Gazzola, V. Zega, A. Corigliano, P. Lotton, and M. Melon. The top portion features a electro-mechano-acoustic finite element model implemented in COMSOL Multiphysics® for free-field conditions, while the bottom shows a fabricated microspeaker and the acoustic measurement setup used in the study.
