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.

Claim (Index 17):
A drum apparatus comprising:\n a drum body having a side wall defining a resonant chamber; a plurality of coupling structures disposed about a circumference of the drum body side wall, the coupling structures adapted for engaging a drum head across an open end of the drum body, in acoustic communication with the resonant chamber, wherein the drum body side wall and coupling structures are formed of a substantially continuous material defining an integral structure of the drum body; and an acoustic port defining an acoustic coupling across, the drum body side wall of the drum shell and having a longitudinal axis extending therethrough; and an extension defining an inner surface of the acoustic port, the inner surface extending radially inward or outward from the drum body side wall, or both, along the longitudinal axis, wherein the acoustic port protrudes from the drum body side wall along the extension.
