- Rockin’ Patent®: US Patent No. 11,189,255
- Filed: 18 September 2020
- In the name of: D’Addario & Company Inc
- Title: Film Formed Snare and Reduced Volume Snare Drumhead
- What’s claimed: “A drumhead, comprising: a layer of a porous material defining a top surface and bottom surface; and a layer of a film material defining a surface in surface-to-surface contact with one of the top surface or bottom surface of the layer of porous material, wherein the layer of film material is configured and attached to the drumhead such that a portion of the film material vibrates against the porous material when the drumhead is struck, thereby producing a snare-like sound.”
- Why this patent rocks: This patent appears to relate to the Evans dB drum heads for snare drums. MusicRadar explains that the drumhead can reduce volume “without losing attack, while also maintaining an authentic fell, […] tone and pitch” by using a “single ply of Evans’ ShockWeave Mesh, bolstered by Kinetic Transfer Foam (KTF) and an Impact Patch.” For more information, see here.
