An electro-acoustically amplified drum consists of a hollow drum shell having at least one open end, a drum head spaced from the open end of said drum shell and supported thereon, and a microphone supported on and positioned within said drum shell and adapted to be connected to an external amplifier and speaker. The microphone is preferably supported in a position spaced from the wall of the drum shell to receive acoustical impulses separately from the drum head and the drum shell. The drum head may be a separate drum head supported on the drum shell in a fixed position or adjustable in relation to the spacing from the open end of the drum shell. Alternatively, the drum head may be supported on a drum shell having a plurality of apertures adjacent to the point of support, said apertures providing acoustical openings separating the drum head from the remainder of the shell which functions as a drum shell resonator.
