摘要

An acoustic energy source that amplifies the stroke of electrically reactive elements having a body with an elastomer filled first cavity, a highly incompressible fluid filling a second cavity, and bores intersecting the second cavity that extend radially outward from second cavity. Quill assemblies in the bores each include an electrically reactive element and a tip projecting radially into the second cavity. A dynamic yoke having a lower portion projecting into the second cavity, and a pressure disk projects into the first cavity. A diaphragm on the body and on a side of the dynamic yoke opposite its lower portion. A fluid forms a film between the dynamic yoke, static yoke and quill tips. Applying alternating electricity reciprocates the tips into and out of the second cavity; reciprocates the dynamic yoke and diaphragm to generate the acoustic energy.
