Patent ID: 8809656

Claim:
A modular assembly for use with an acoustic style musical drum assembly having one or two drum heads to assist in the uniform distribution of tension applied to the drum head for the purpose of producing a clear and uniform frequency pitch when the drum head is struck by any object or sound waves, the modular assembly comprising: a 360° continuous distensible annular bladder which conforms its profile shape relative to a regulated delivery of a compressed air pressure introduced within said bladder at pressures ranging from 0- 100 PSIG relative to an atmospheric pressure local to the bladder, said bladder disposed between a rim and a hoop, the rim and hoop positioned proximate a perimeter of either drum head of the drum assembly; a length of flexible conduit fluidly connecting an internal area of said bladder with a remote gas pressure reserve and supply control source; a gas pressure regulator to control gas pressure within the bladder wherein the gas pressure regulator is controlled by an operator via hand, foot, mouth or electric signal according to the operator preference; and a liquid carbon dioxide or compressed gas cylinder for containing a reserve supply of liquid carbon dioxide or compressed gas at pressures greater than 100 PSIG while including a fixed outlet gas pressure regulator for the delivery of gas at pressures lower than 100 PSIG.
