Abstract:

A rhythm instrument utilizing improved sound producing element combinations for the bass, tom-tom and snare sections of an electronic drum to provide an advantageous audio reproduction of the sounds of conventional drums. Specifically, the improved sounding elements provide more accurate snap, staccato, roll, and rim sounds. In overall concept, the audio producing mechanisms include dynamic impact between an extended vibrationally displaceble element secured on opposing ends thereof to a base surface and a resilient band stretched across an upper surface of the vibrational element. Sounds are produced by causing a striker arm having a hard tip portion member to impinge upon the resilient band causing it in turn to strike the displaceable element. A bass sound is provided by a single such unit utlizing a wide metal strip as the displaceable element. Tom-tom sounds are provided by multiple units having wires of varying lengths utilized as the vibrationally displaceable element with the widths being more narrow than that of the bass unit.
