Abstract
A loudspeaker diaphragm mounting system where there is a perimeter frame to which is mounted a planar flexible diaphragm having electrically conductive elements thereon. The frame has two perimeter sections which have matching perimeter grooves to receive an elongate tensioning member which presses the edge portion of the diaphragm into at least one of the grooves. By controlling the force with which the two frame sections are pushed together, tension on the diaphragm can be controlled.
