Abstract:
1. An analog electronic drum set comprising: a first tom-tom with a batter head with tensioned membranes without a resonator, of which a diameter is 6 inches (15.24 cm); a second tom-tom of which a diameter is 8 inches (20.32 cm); a third tom-tom of which a diameter is 10 inches (25.4 cm); a bass drum with a horizontal batter head of which a diameter is 12–14 inches (30.48–35.56 cm); a snare drum of which a diameter is 8 inches (20.32 cm), having a chain belt adjustably connected to the snare drum to selectively contact against the batter head; a hi-hat cymbal, of which a diameter is 6–8 inches (15.24–20.32 cm), having a top disk made of a non-magnetic metal, and a bottom disk made of a magnetic metal, which has a spring around a shaft between the bottom and top disks to provide an elastic force to separate the top disk from the bottom disk; a first cymbal, of which a diameter is 8–10 inches (20.32–25.4 cm), having a disk made of a non-magnetic metal; a second cymbal, of which a diameter is 10–12 inches (25.4–30.48 cm), having a disk made of a non-magnetic metal; a sympathetic magnetic piece of an arch shape and abutting inner surfaces of the respective batter heads with adjustable pressure, which is located in a range from an edge of the sympathetic magnetic piece towards a center of the respective batter head and is 20–45% of a radius of the respective batter head of all tom-toms, the bass drum, and the snare drum, and the sympathetic magnetic piece is made of a magnetic board material which is able to resonate easily with the vibrations of the batter head; a sympathetic magnetic piece is connected with the cymbal by the adjusting bolt, and wherein the sympathetic magnetic piece is made of a magnetic board material which can resonate easily with the vibrations of the cymbal; an augmented microphone, that electrically amplify the induced current from vibrations of the sympathetic magnetic piece, and distances to the sympathetic magnetic piece are adjustable, located at a position corresponding to that of the respective sympathetic magnetic piece; a pedal assembly, which has a pulley to rotate towards a predetermined direction, and a foot pedal which denies the predetermined direction by stepping downward and is rotated by the pulley, and a drumstick mounted on the pulley at a side of the pedal to rotate toward the front and down direction along with the pulley to beat the horizontal batter head of the bass drum; an augmented microphone, that electrically amplifies the induced current from vibrations of the bottom disk of the hi-hat cymbal made of a magnetic metal; and a mallet for hitting elements of the analog electronic drum set, being 39–45 cm in an overall length, and having a front beating portion with a diameter of 3.5–4 mm and a length of 8–10 mm, a rear portion with a diameter of 8–10 mm and a length of 23–35 cm, a middle portion between the front portion and the rear portion with a diameter spreads out gradually of 2–2.5 mm and a length of about 10–15 cm, and a mass of 12–18 g.
