Claim 6

A kit for converting a conventional drum to an electronically triggered drum, the conventional drum having a peripheral sidewall and a drumhead, comprising: a pad; a pickup board; at least three brackets adapted to be secured to the sidewall of the conventional drum, the pickup board and the pad being supported by said brackets; and a pair of electronic pickup assemblies, each assembly adapted to be secured to a bottom surface of the pickup board in order to detect mechanical vibration of said drumhead when impacted from above.

Claim 7

The kit of claim 1 wherein each electronic pickup assembly further comprises: a transducer; a jack; a wire lead extending between said transducer and said jack.

Claim 8

The kit of claim 5 wherein one of said electronic pickup assemblies further comprises: a shock absorber adapted to be mounted between said transducer and said pickup board.

Claim 9

The kit of claim 5 wherein one of said jacks is longer than the other.

Claim 12

The method of claim 8 and further comprising the step of; mounting brackets to the sidewall of the conventional drum to support said pad and pickup board beneath said drumhead.

Claim 13

The method of claim 9 wherein said brackets are located a predetermined distance from said drumhead so that a top surface of said supported pad is in contact with a bottom surface of said drumhead.

Claim 14

The method of claim 8 wherein each electronic pickup assembly includes a transducer, a jack, and a wire lead connected therebetween, and each said securing step further comprises the steps of: securing the respective transducer to a bottom surface of the pickup board; and mounting the respective jack in a hole formed in the sidewall of the conventional drum.

Claim 15

The method of claim 11 further comprising the step of; drilling holes in the sidewall of the conventional drum, said holes sized to hold said jacks in an interference fit.

Claim 16

The method of claim 8 wherein two said electronic pickup assemblies are mounted to an underside of said pickup board and further comprising the steps of: mounting a first of said electronic pickup assemblies beneath a center portion of the drumhead; and mounting a second of the electronic pickup assemblies adjacent to the sidewall of the drumhead.

Claim 17

The method of claim 13 and further comprising the step of: mounting a shock absorber between said second transducer and said pickup board.

Claim 18

An electronically triggered drum, the drum having a peripheral sidewall, a drumhead sized to cover a first open end of the peripheral sidewall, a rim for retaining the drumhead over the first open end, and means for tightening said rim downwardly upon said retained drumhead, and further comprising: a pad located beneath said drumhead; a pickup board located beneath said pad; means for supporting said pad and said pickup board so that a top surface of said pad resides in complete surface contact with a bottom surface of said drumhead and contiguously with an uppermost portion of the peripheral sidewall, said supporting means being connectable to said sidewall; a first electronic pickup assembly mounted to a bottom surface of said pickup board proximate to the center of said drumhead; a second electronic pickup assembly mounted to a bottom surface of said pickup board adjacent to the sidewall of said drumhead; and a shock absorber mounted between said pickup board and second electronic pickup assembly.

Claim 19

An electronically triggered drum, the drum having a peripheral sidewall, a drumhead sized to cover a first open end of the peripheral sidewall, a rim for retaining the drumhead over the first open end, and means for tightening said rim downwardly upon said retained drumhead, and further comprising: a pad located beneath said drumhead; a pickup board located beneath said pad; means for supporting said pad and said pickup board so that a top surface of said pad resides in complete surface contact with a bottom surface of said drumhead and contiguously with an uppermost portion of the peripheral sidewall, said supporting means being connectable to said sidewall; a first electronic pickup assembly mounted to a bottom surface of said pickup board proximate to the center of said drumhead; a second electronic pickup assembly mounted to a bottom surface of said pickup board adjacent to the sidewall of said drumhead; and a shock absorber mounted between said pickup board and second electronic pickup assembly.

Claim 20

A drum which has been converted by a conversion kit from a conventional drum to an electronic drum, the electronic drum having a peripheral sidewall and a drumhead, comprising: a pad mounted on the underside of the drumhead in complete surface contact therewith; a pickup board mounted on the underside of the pad, and a pair of electronic pickup assemblies, each assembly adapted to be secured to a bottom surface of the pickup board in order to detect mechanical vibration of said drumhead when impacted from above.

Claim 21

A drum which has been converted by a conversion kit from a conventional drum to an electronic drum, the electronic drum having a peripheral sidewall and a drumhead, comprising: a pad mounted on the underside of the drumhead in complete surface contact therewith; a pickup board mounted on the underside of the pad, and a pair of electronic pickup assemblies, each assembly adapted to be secured to a bottom surface of the pickup board in order to detect mechanical vibration of said drumhead when impacted from above.

Claim 22

The drum of claim 16 wherein said pad is about 1" thick and circular in shape.

Claim 23

The drum of claim 16 wherein said pickup board is about 1/4" thick and circular in shape.

Claim 24

The drum of claim 16 which further comprises bracket means for securing said pad and pickup board to said sidewall, said bracket means comprising; at least three brackets adapted to be secured to the sidewall of the conventional drum, the pickup board and the pad being supported by said brackets.

Claim 25
