Two piece drum i.e. djembe, has structure projecting inward from base to basin, where inward projecting structure has shape of collar that continues from base to basin, and base, basin and collar are formed as single piece
The drum (1) has a structure (9) projecting inward from a base (3) to a basin (5), where the inward projecting structure has a shape of a collar that continues from the base to the basin. The base, the basin and the collar are formed as a single piece, where the drum is made of wood, glass fiber, al...

| description | The drum (1) has a structure (9) projecting inward from a base (3) to a basin (5), where the inward projecting structure has a shape of a collar that continues from the base to the basin. The base, the basin and the collar are formed as a single piece, where the drum is made of wood, glass fiber, aluminum cast or ceramic. A cylindrical section is movable in the basin, and the structure and/or the collar are adapted to a shape of the drum. The structure or the collar is inserted into the drum in a self-centered manner.
Die Erfindung betrifft eine Trommel, insbesondere eine Trommel mit einer innen liegenden Taille. Eine solche Djembe 1 umfasst einen Fuß 3, einen Kessel 5 und ein Trommelfell 7. Gemäß der Erfindung ragt zusätzlich von dem Fuß 3 eine Struktur 9 in den Kessel 5. Diese kragenförmige Struktur 9 setzt den Fuß 3 in den Kessel 5 hinein fort. Durch diese Maßnahme wird, vermutlich infolge einer veränderten Helmholtz-Resonanz, die Grundfrequenz des Basstons herabgesetzt. |
