DRUM HEAD WITH A PLURALITY OF CUSHIONED OPENINGS

Abstract

A drum head, particularly for bass drum, has rounded openings close to its outer margin, which are padded with U-shaped toroidal dampers of felt or open-cell plastic foam.

Claims

1. A drum head, comprising: a plurality of cutouts, equally distant to the margin of the drum head; and a cushion encompassing each cutout, made of medium-rigid, open-cell plastic foam damping material.

2. (canceled)

3. (canceled)

4. The drum head of claim 1, wherein said cushions are torus shaped with U-shaped cross section.

5. A drum head, comprising: a plurality of cutouts, equally distant to the margin of the drum head; and a cushion encompassing each cutout, made of felt composition damping material.

6. The drum head of claim 5, wherein said cushions are torus shaped with U-shaped cross section.

Description

DESCRIPTION OF THE INVENTION ALONG TO THE DRAWINGS

[0015] FIG. 1 shows a simplified bassdrum 1 (without head tensioners) with the drum corpus 1, the rims that hold the drumheads 2 and 3, the resonance head 4 with a typical vibrational pattern 5, and an optional damping matress inside on the bottom 6. A series of said toroidal dampers 7 and its siblings, which enclose the holes cutout from the head to form venting ports with reduced turbulence and which are responsible for the gradually decreasing vibrational patterns 5 towards the drum head margins.
