Acoustic drum shell for producing sound, has triangle shaped case on which drumhead is installed, where tension in drumhead is realized by installing support triangle which pushes drumhead with supports located on apex and sides of triangle

摘要

The shell has an equilateral triangle shaped case (1) on which a drumhead (2) is installed and stuck in a frame (4). Tension in the drumhead is realized by installing a support triangle (5) on the frame, which pushes the drumhead with supports (7, 9) distributed on apex and sides of the triangle using the screw, through a locking unit (6). Edges of the case are cut at an angle of 45 degree for limiting the inclination of the drumhead.
