ABSTRACT:
One of a pair of concentric ring hoops overlaps the other and holds the perimeter edge of a drum head vibratile element in tension between the mating overlapping faces of the hoops. The hoops are held together by a tensioning bolt threadable into a bracket connected to a lower hoop which has another skin stretched between a stepped inner annular groove on its inner face edge. A drum shell made of a composite of rigid foam interior spaced apart by a pair of epoxy impregnated carbon fibresheets is held by the lower second drum skin into enclosing engagement on its upper perimeter edge with an inner stop flange and vertical wall face of the inner hoop ring of the drum head vibratile skin assembly.
