<p>A cajon 2 with a tonal adjustment mechanism comprises: a cuboid shaped box including a front panel (fig. 1, 4) defining a playing surface, a bottom panel 6, a top panel 8, first and second side panels 10, 12 and a rear panel 14. A plurality of snare wires 18 are mounted within the box on a support and at least one lever arm 22, 24 is pivotally mounted within the box for pivotal movement about an axis extending parallel to and spaced inwardly from the playing surface. Pivotal movement of the lever arm displaces the snare wires between an inoperative position, wherein the snare wires are spaced from the playing surface, and at least one operative position, wherein the snare wires rest against an inner face of the playing surface. The snare wires are adjustable between the inoperative and operative positions by rotation of a cam having a cam surface acting against the support upon which the snare wires are mounted. The cam is rotatable by means of an operating member located on the exterior of the box to adjust the position of the snare wires with respect to the playing surface between the inoperative and operative positions.</p> |
