Abstract: The present disclosure relates generally to a drum apparatus with advanced acoustic response and methods of manufacturing the drum apparatus. The drum apparatus includes an integral drum body having a side wall defining a resonant chamber. The integral drum body is formed by an additive manufacturing process or with a volume printing material that shapes the side wall to define an acoustic response of the drum apparatus. The side wall is shaped to define a top perimeter region and a bottom region of the integral drum body. The top perimeter region defines a top opening to the resonant chamber and the bottom region defines a bottom of the resonant chamber, opposite the top perimeter region. The side wall has a thickness or mass distribution controlled by the additive manufacturing process or defined by the volume printing material to modulate the acoustic response of the drum apparatus.

Abstract: A drum pedal apparatus includes a base or base plate, a footboard pivotably coupled to the base plate, the footboard operable to drive a mallet to strike a drum, and a clamping mechanism attached to the base plate adjacent the footboard. The clamping mechanism includes a first lever arm adapted to couple the drum pedal apparatus to a drum hoop of a drum, a pivot assembly coupled to the first lever arm, and a second lever arm coupled to the first lever arm via the pivot assembly. The second lever arm can be adapted to operate the clamping mechanism, where the clamping mechanism applies a selected clamping force to the drum hoop responsive to the second lever arm pivoting relative to the first lever arm at the pivot assembly.

Abstract: A drum apparatus with advanced acoustic response is provided. The drum apparatus includes a drum body having a side wall defining a resonant chamber. The side wall can include a plurality of coupling structures disposed about its circumference; e.g., as adapted for engaging a drum head across an open end of the drum body, in acoustic communication with the resonant chamber. The drum body side wall and coupling structures can be formed of a substantially continuous material defining an integral structure of the drum body.
