Abstract
An electroacoustical drum has a drum shell and a drum head having an outside surface and an inside surface. A fastening assembly secures the drum head to the drum shell with the drum head in tension. A transducer has a vibratable surface, so that vibration of the vibratable surface produces a corresponding electrical signal from the voice coil. Striking the outer surface of the drum head with a drumstick produces a corresponding electrical signal from the transducer, while allowing a musician striking the drum head outer surface with the drumsticks to perceive substantially the same feel perceived by correspondingly striking an acoustic drum.
