Electroacoustical drum

An electroacoustical drum comprising,

• a drum shell,
• a drum head having an outside surface and an inside surface,
• a fastening assembly securing said drum head to said drum shell with said drum head in tension,
• cone structure formed with an annular outer rim and a lower central portion,
• an electroacoustical transducer carried by said lower central portion so that vibration of said cone structure produces a corresponding electrical signal from said electroacoustical transducer,
• the annular outer rim of said cone structure being connected to an annular portion of the inside surface of said drum head adjacent to said drum shell so that striking the outer surface of said drum head with a drumstick produces a corresponding electrical signal from said electroacoustical transducer while allowing a musician striking the drum head outer surface with drumsticks to perceive substantially the same feel perceived by correspondingly striking an acoustic drum,
• the drum head outer surface constructed and arranged to present substantially the same resistive forces to drumsticks when struck presented by an acoustic drum correspondingly struck.

An electroacoustical drum, comprising:

• a drum shell;
• a drum head having an outside surface and an inside surface;
• a fastening assembly securing said drum head to said drum shell with said drum head in tension;
• a transducer having a vibratable surface formed with an annular outer rim, so that vibration of said vibratable surface produces a corresponding electrical signal;
• and
• a connecter connecting the annular outer rim of said vibratable surface to an annular portion of the inside surface of said drum head adjacent to said drum shell so that striking the outer surface of said drum head with a drumstick causes said vibratable surface to vibrate while allowing a musician striking the drum head outer surface with drumsticks to perceive substantially the same feel perceived by correspondingly striking an acoustic drum, the drum head outside surface constructed and arranged to present substantially the same resistive forces to drumsticks when struck presented by an acoustic drum correspondingly struck.

An electroacoustical drum, comprising:

• a drum head having an outside surface and an inside surface;
• a transducer having a vibratable surface, so that vibration of said vibratable surface produces a corresponding electrical signal;
• a body defining a frusto-conical plenum disposed between said inside surface of said drum head and said vibratable surface such that striking the outer surface of said drum head with a drumstick causes said vibratable surface to vibrate while allowing a musician striking the drum head outer surface with drumsticks to perceive substantially the same feel perceived by correspondingly striking an acoustic drum;
• and
• a fastening assembly fixing the position of said drum head with respect to said body with said drum head in tension, the drum head outside surface constructed and arranged to present substantially the same resistive forces to drumsticks when struck presented by an acoustic drum correspondingly struck.

An electroacoustical acoustic drum pickup assembly, comprising:

• a housing having a first port in pressure communication with atmosphere and a second port adapted to be insertable into an air vent located in the shell of said drum;
• a transducer disposed within said housing and having a vibratable diaphragm, so that vibration of said vibratable diaphragm produces a corresponding electrical signal;
• and
• a first surface of said diaphragm in pressure communication with said first port, and a second surface of said diaphragm in pressure communication with said second port so that striking the drum head of said drum with a drumstick causes said vibratable diaphragm to vibrate while allowing a musician striking the drum head with drumsticks to perceive substantially the same feel perceived by correspondingly striking an acoustic drum not provided with an electroacoustical pickup assembly, the drum head outside surface constructed and arranged to present substantially the same resistive forces to drumsticks when struck presented by an acoustic drum correspondingly struck.
