Abstract
Abstract A pad for an electronic drum has a vibration responsive plate that is mounted on a cushion and has on its upper surface a relatively thin buffer pad, the plate having cushioning means on its outer edge between it and peripheral supporting structure, so that the feel of the drumhead is quite natural to the player and that vibrations from the frame or supporting structure are insulated from the plate, and that the plate vibrations are not adversely affected, the plate carrying a microphone or other sound pick-up means.
