摘要:
A drumhead comprising a mesh membrane having a bottom surface and a damper contacting at least a portion of the bottom surface for improved rebound. Also, a practice drumhead assembly including a mesh membrane held in substantially fixed relation to an acoustic membrane. The assembly preferably includes an annular tensioning ring for tensioning the mesh membrane, and an engagement member for substantially fixing the mesh membrane relative to the acoustic membrane. Additionally, a tensioning ring for a drumhead comprising a cylindrical rod with a turnbuckle that is rotated to increase the diameter of the tensioning ring.
