摘要： An acoustic transducer comprises one or more electromagnetic motors that drive one or more sets of multiple diaphragms to provide acoustically efficient loudspeaker systems having dimensions that allow use in applications that would be difficult or impossible with traditional transducers. The diaphragms may be driven directly, inertially or fluidically. If diaphragms are driven by rods that pass through holes in the diaphragms, noise may be generated by air that leaks through the pass-through holes. This noise may be reduced or eliminated by measures that reduce or eliminate the air leakage.
