ABSTRACT:
An acoustic drum capable of triggering an electronic sound source is provided by a combination of a drum body shell, conventional drum heads held at adjustable tension across open ends of the shell, and a sound-to-electrical transducer mounted within an open space of the interior or exterior shell wall surface. The sound-to-electrical transducer is connected to an audio jack assembly which in turn allows the drum to be connected to conventional downstream electronics. The sound energy attenuating characteristics of the mounting material and the surrounding shell wall prevent the transducer from being falsely triggered by ambient sound exterior to the drum, by sympathetic vibrations of the drum, and resists false triggering due to lightly, inadvertently hitting the drum stand.
