Drumhead tone control device |
摘要 |
A drumhead tone control device employs an annular configuration of polyester film tightly adhered to the periphery of a drumhead membrane. The annular configuration of the tone control device includes radial and/or circumferential relief. The relieved tone control device disrupts transmission of vibrations reflected from the drumhead membrane/drum shell interface. Disruption of reflected vibrations improves the overall tonal quality of the drumhead while use of a tightly adhered polyester sheet close to the periphery of the drumhead playing surface minimizes undesirable alteration of the attack characteristics and fundamental tone of the drumhead.
