A collapsible drum comprising:
- a drum head;
- an elongated drum base forming a resonance cavity extending from an upper end to a lower end wherein a cross-section of the resonance cavity has a circular shape, and wherein a circular cross-section at the upper end is greater in diameter than a circular cross section at the lower end, and at least one circular cross-section between the upper end and lower end is smaller in diameter than the cross-section at the upper end and the cross-section at the lower end, and wherein cross-sections of the resonance cavity have a smooth uninterrupted circular shape over a majority of the resonance cavity from the upper end to the lower end;
- wherein the drum base comprises at least a first base portion and a second base portion arranged along a longitudinal axis;
- wherein the first base portion is in the form of a ring having an inner wall and an outer wall extending along the longitudinal axis from an upper end to a lower end, and wherein the inner wall defines a first resonance cavity portion, wherein the inner and outer walls have a circular shaped cross-section having a gradually varying cross-sectional diameter from an upper end to a lower end, wherein the circular shaped cross-section is uninterrupted over a majority of the inner wall from the upper end to the lower end, and wherein the upper end of the first base portion is adapted to receive the drum head and the lower end has a first engaging portion, the first engaging portion being disposed proximate the lower end and distant from the upper end;
- wherein the second base portion is in the form of a ring having an inner wall and an outer wall extending along the longitudinal axis from an upper end to a lower end, and wherein the inner wall defines a second resonance cavity portion, wherein the inner and outer walls have a circular shaped cross-section having a gradually varying cross-sectional diameter from an upper end to a lower end, wherein the circular shaped cross-section is uninterrupted over a majority of the inner wall from the upper end to the lower end, and wherein the upper end of the second base portion has a second engaging portion, the second engaging portion being disposed proximate the upper end and distant from the lower end;
- the first engaging portion adapted to removably engage and disengage the second engaging portion wherein the first and second engaging portions are adapted to engage and disengage through rotation of the first engaging portion with respect to the second engaging portion;
- and
- the first base portion being sized to at least partially receive the second base portion within the first resonance cavity portion;
- and
- a lighting effects unit disposed in the resonance cavity and having a plurality of lights, at least one of a microphone, motion or pressure sensor, a power supply and a processor adapted to energize a light in response to drum play;
- and
- a plurality of bumpers disposed circumferentially on the inner wall of the first base portion.
