Abstract

A drum includes a hollow drum body, a drum skin frame supported by the walls of the hollow drum body, a drum skin stretched on the drum skin frame, and a drum head frame tightly clamping the peripheral; edges of the drum skin frame and the drum skin. A damping member, disposed between the drum head frame and the drum skin frame, absorbs the vibrations of the two drum frames and filters out the sound they produce whenever the drum skin is beaten.

a hollow body with a top open end;

a looped drum skin frame in contact with said top open end of said hollow body;

a drum skin having a peripheral edge, said drum skin being tightly stretched on said drum skin frame;

a looped drum head frame provided at said top open end above said drum skin frame, said drum head frame being screwed to said hollow body for tightly clamping the peripheral edge of said drum skin and said drum skin frame against said hollow body, said drum head frame having a looped projection around said drum skin frame and a shoulder inwardly projecting from said looped projection above the peripheral edge of said drum skin; and

a damping member made of a resilient material and being disposed between said drum skin frame and said drum head frame for providing isolation between said drum skin frame and said drum head frame, said damping member having a flange member between the peripheral edge of said drum skin and said shoulder of said drum skin head frame;

whereby, said damping member absorbs vibrations of said drum skin frame and drum head frame when said drum skin is beaten.
