发明名称 Drum practice pads and drum pad musical instruments
摘要 A drum practice pad comprised of a flat circular piece of hard material having a flat circular piece of resilient material bonded to the upper surface thereof, the piece of resilient material having a diameter which is less than the diameter of the piece of hard material. Sound insulating cushions are affixed to the lower surface of the hard material for supporting the hard material in an acoustically-floating manner during use. A plural-pitch set of drum pads is provided by using a second drum pad of this same construction, but with the piece of hard material having a different thickness or diameter.
