Abstract
A handpan comprises a hollow base body, composed of a lower shell and an upper shell, each in the form of a spherical segment, which are connected to one another, preferably glued, at their mutually facing outer edges, a basic tone field preferably arranged centrally on the upper shell, further tone fields arranged annularly on the upper shell, preferably around the basic tone field, a resonance opening in the lower shell, and at least one further resonance opening in the lower shell, wherein the at least two resonance openings are arranged decentrally in the lateral rising zone of the lower shell.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0022] As can be seen from FIG. 1 to 4, the handpan shown there has a hollow base body 1 which is composed of a respective hemispherical segment-shaped flat lower shell 2 and an upper shell 3 of corresponding basic shape. The two shells 2, 3 are glued together over their entire circumference at their facing outer edges 4.
[0023] As can be seen in particular from FIGS. 1 and 2, a central basic tone field 5 is configured on the upper shell 3. Around this, eight further tone fields 6.1 to 6.8, which are tuned differently due to different diameters and shapes, are arranged annularly. This design of the upper shell 3 also applies to all further embodiments according to FIG. 7 to 10, so that no further description of the upper shell of these embodiments is necessary in this respect.
[0024] In the embodiment example of the handpan shown in FIG. 1 to 6, two resonance openings 7.1, 7.2 are introduced into the lower shell in a decentralized manner in the lateral, rising zone 8 of the lower shell 2, so that a zone 9 not occupied by the resonance openings 7.1, 7.2 is present centrally. The two resonance openings 7.1, 7.2 are arranged uniformly with respect to the circumferential direction U of the lower shell 2 due to their 180° offset opposition and have a matching diameter D7. The central zone 9 of the lower shell 2 not occupied by the resonance openings 7.1, 7.2 has a surface dimension F9 substantially corresponding to the diameter D7. The same applies to the distance A7 between the outwardly pointing edges 11 of the resonance openings 7.1, 7.2 and the outer edge 4 of the lower shell 2.
[0025] In contrast to the previous embodiment, the embodiment shown in FIGS. 7 and 8 has three resonance openings 7.1, 7.2, 7.3 in the lower shell 2, which in turn are arranged decentrally in the laterally rising zone 8 of the lower shell 2. As can be seen in particular from FIG. 7, the arrangement of the resonance openings 7.1, 7.2, 7.3 is here also uniform in the circumferential direction U, so that these openings are arranged offset from one another by an angle of 1200 in the circumferential direction U with respect to one another. Surface dimension F9 and distance A7 analogously essentially correspond to the matching diameter D7 of the resonance openings 7.1, 7.2, 7.3.
[0026] Finally, in contrast to the previous embodiments, the embodiment shown in FIGS. 7 and 8 has four resonance openings 7.1, 7.2, 7.3, 7.4 in the lower shell 2, which are again arranged decentrally in the laterally rising zone 8 of the lower shell 2. As can be seen in particular from FIG. 9, the arrangement of the resonance openings 7.1, 7.2, 7.3, 7.4 is again uniform in the circumferential direction U, so that these openings are arranged offset from one another by an angle of 90° in the circumferential direction U with respect to one another. Surface dimension F9 and distance A7 analogously essentially correspond to the matching diameter D7 of the resonance openings 7.1, 7.2, 7.3, 7.4.
