BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 shows an exemplary percussion instrument.

(2) FIG. 2 shows a cover plate with rib.

(3) FIG. 3 is a sectional view through a percussion instrument with multiple resonance bodies.

(4) FIG. 4a is a perspective view of an interchangeable insert inserted into an opening in a cover plate.

(5) FIG. 4b is a perspective view of an alternative interchangeable insert.

DETAILED DESCRIPTION

(6) FIG. 1 shows an exemplary percussion instrument 1. The percussion instrument 1 has multiple tone bars 2, which are arranged one after the other in the x-direction. The tone bars 2 are fastened to the upper side of the cover plate 6 by two connecting elements 18. Due to the height of the connecting element 18, each tone bar 2 has an assigned gap d from the cover plate 6, wherein the cover plate 6 seals the resonance bodies 4 with respect to the tone bar 2. The resonance box 3 is located within a frame 15 of the percussion instrument 1.

(7) FIG. 2 shows a cover plate 6 of a percussion instrument 1 with multiple openings 7. Some of the openings 7 are sealed with plugs 10. Furthermore, the cover plate 6 has sliders 11 that are connected to the cover plate 6 in a movable manner. Through a corresponding positioning the slider 11 opposite the opening 7 in the cover plate 6, the cross-sectional area S of the sound hole 8 can be reduced. An additionally attached rib 14 runs along the central axis of the cover plate 6 and separates adjacent openings 7 from each other.

(8) FIG. 3 shows a section through a percussion instrument 1. Each tone bar 2 is assigned a resonance body 4 with a resonance chamber 5. Depending on the assigned tone bar 2, the volume of the resonance chamber 5 and/or the dimensions L, H of the neck 9 change.

(9) FIGS. 4 a) and b) show possibilities for influencing the sound characteristics of the percussion instrument 1. In FIG. 4 a), an interchangeable insert 12 is inserted into an opening in the cover plate 6. This reduces the cross-sectional area S of the neck 9 compared to the initial area and also extends the neck 9 by the height of the collar 16. FIG. 4 b) shows an interchangeable insert 12 belonging to the percussion instrument 1 with which the volume of a resonance chamber 5 can be reduced. The interchangeable insert 12 has flexible spacers 17 on its outer side. These prevent the interchangeable insert 12 from slipping within the resonance chamber 5 and reduce the transmission of disrupting vibrations of the interchangeable insert 12 to the resonance body 4 and/or the resonance box 3.
