Abstract
An electronic hi-hat 1 has a rod movable up and down with an operation of a player. A top cymbal 2 has a striking surface that can be struck by the player. A bottom cymbal 3 comes into contact with or separates from the top cymbal 2. An optical sensor 7 detects separation dimension between the top cymbal 2 and the bottom cymbal 3. The optical sensor 7 detects separation dimensions of a plurality of areas that are displaced with inclinations of the top cymbal 2 and the bottom cymbal 3 with respect to the rod r. The plurality of areas where the separation dimensions are detected are located on a common circumference of the top cymbal 2 and the bottom cymbal 3 around the rod r as a center.
Claims3
An electronic cymbal comprising:
- a pad having a striking surface;
- a frame supports the pad;
- an edge sensor, detecting a strike by the player, is attached to a peripheral edge portion of the frame, the pad extends from a center toward a peripheral edge portion having a curvature R on an underside of the pad from its center toward the peripheral edge portion, and the pad includes a continuous circumferential protrusion in the peripheral edge portion of the underside of the pad and located directly on the curvature R;
- the frame continuously extends from a center toward the peripheral edge portion;
- and
- the peripheral edge portion of the frame is continuous to its peripheral edge with the frame having the curvature R from its center toward an inner end of the peripheral edge portion and having a curvature R′ from the inner end of the peripheral edge portion toward an outer end of the peripheral edge portion and the frame continuously extends from its center toward the outer end of the peripheral edge portion and is formed to have a larger inclination angle than an inclination angle of the peripheral edge portion of the pad.
