An electronic drum having multiple sound sources with rapidly detachable striking elements and transducers. The drum may contain one or more striking elements each producing a separate electrical output signal. A separate piezoelectric transducer is attached to each striking element. The drum includes a base structure to which various acoustically dampening compressible elements are attached. The striking elements are removably attached to the compressible elements and are acoustically isolated from one another so that vibrations caused by hitting one striking element are not picked up by the transducers attached to the other striking elements. Transducers are attached to the striking elements by first bonding resilient elements to the striking elements and then bonding the transducers to the resilient elements. The electronic drum permits a drummer to employ conventional acoustical “sticking”techniques and may be used to simulate various other percussion type instruments.

An electronic drum comprising: a rigid base; first and second striking elements mounted on said base, said striking elements producing vibrations when impacted; first and second transducer means acoustically coupled respectively to said first and second striking elements for converting said vibrations in said first and second striking elements into electrical signals; resiliently compressible foam element means interposed between said base and said striking elements for reducing impact shock experienced by a performer when striking said striking elements and also for acoustically isolating said striking elements from one another; and detachable fastener means interposed between said base and said striking elements for detachably fastening said striking elements to said base thereby permitting quick removal of said striking elements from said base when said striking elements need to be replaced.
