Abstract
Abstract An auxiliary electronic sound source for an electronic drum. The auxiliary sound source is attached to a conventional electronic drum and enables a drummer to practice acoustical "sticking" techniques involving a drum rim. The auxiliary sound source includes a striking element with an acoustically isolating connection to the electronic drum. A piezoelectric material transducer is attached to the striking element to convert impact induced vibrations in the striking element into an electrical output signal. In an alternative embodiment, the piezoelectric transducer is attached to a mounting plate detachably connected to the striking element.
