Abstract
A frame body fixed to a membrane 10 is divided into multiple long-side frame bodies 11 and a short-side frame body aligned in a peripheral direction of a frame 3. Tension is applied to the frame body 10 by pulling each frame body 11, 12. Accordingly, it is not necessary to make the shape of each frame body 11, 12 consistent with the frame 3 (support part 30) in a complicated polygonal shape, and the shape of each frame body 11, 12 can be formed as a linear shape. Therefore, the shape of each frame body 11, 12 hardly varies. In addition, even if the shape of each frame body 11, 12 varies, tension can be uniformly applied to the membrane 10, as it is configured that each frame body 11, 12 is pulled to apply tension to the membrane 10.
Claims17
A drumhead, comprising:
- a membrane, forming a striking surface of a percussion instrument;
- and
- a plurality of frame bodies, connected to an outer edge of the membrane and aligned along the outer edge of the membrane,
- wherein in a case of being installed to the percussion instrument, each of the plurality of frame bodies is pulled to apply tension to the membrane,
- wherein the plurality of frame bodies are at least formed by a plurality of first frame bodies and a second frame body which is arranged between the plurality of first frame bodies and in which two ends are overlapped with adjacent ones of the first frame bodies, and
- by pulling the second frame body, the first frame bodies are pressed against the second frame body.
A tension application method, applying tension to a membrane of a drumhead which comprises:
- the membrane, forming a striking surface of a percussion instrument;
- and a plurality of frame bodies connected to an outer edge of the membrane and aligned along the outer edge of the membrane, wherein the plurality of frame bodies are at least formed by a plurality of first frame bodies and a second frame body which is arranged between the plurality of first frame bodies and in which two ends are overlapped with adjacent ones of the first frame bodies, and the tension application method comprising:
- applying the tension to the membrane by pulling each of the plurality of frame bodies in a case where the drumhead is installed to the percussion instrument, and
- by pulling the second frame body, the first frame bodies are pressed against the second frame body.
