Abstract
A musical drumhead having a top surface and bottom surface and a means attached to the drumhead for discharging an aromatic vapor. The musical drumhead is comprised of a membrane having means to vent the aromatic vapors through the top surface of the drumhead and disperse the vapors into the surrounding environment. Vent means comprises a plurality of vent holes in the drumhead membrane through which the vapors are discharged. The primary source of the vapors is a pad of porous material impregnated with an aroma producing liquid with a pleasing fragrance. The pad of porous material is attached in some conventional manner to the bottom surface of the drumhead immediately beneath the vent holes. The striking of the drumhead produces a vibration in the drumhead membrane which, in turn, excites the molecules in the air beneath and above the membrane. The aromatic oil vapors gathered around the impregnated pad are initially forced in all directions by the excited air and then dispersed through the vent holes into the surrounding areas.
