Description

Resonanzboden. Die Resonanzböden für Musikinstrumente sind bekanntlich aus Hölzern zusammengesetzt, die je nach der Farbe und der Dichte der Jahresringe ausgewählt sind. Demgegen" über besteht die Erfindung darin, die einzelnen Hölzer eines Resonanzbodens nach gleichen, annähernd gleichen oder sich gleichmäßig ändernden Verhältnissen aus Elasti.zitätsmodul und spezifischem Gewicht anzuordnen. Unter dem Elastizitätsmodul wird das Verhältnis zu einer Deformation erforderlichen Kraft zur Größe der Deformation verstanden.Soundboard. The soundboards for musical instruments are well known composed of woods, depending on the color and density of the annual rings are selected. In contrast, the invention consists in the individual woods of a soundboard according to the same, approximately the same or evenly changing To arrange ratios of elasticity module and specific weight. Under The modulus of elasticity is the ratio to a deformation required force understood the size of the deformation.

Beispielsweise kann man für einen aus zehn Brettern bestehenden. Resonanzboden Hölzer wählen, deren spezifische Gewichte folgende sind: s 0,419 0,404 0,465 0,388 0,454 0,417 0,367 0,4.88 0,459 0,434.For example, you can use a board made up of ten boards. Select soundboard woods whose specific weights are as follows: s 0.419 0.404 0.465 0 388 0.454 0.417 0.367 0,4.88 0.459 0.434.

Ihre Elastizitätsmoduln hatten die Werte: E 1167 1201 1533 136o 1714 1587 1322 -1628 1395 1254. Das Ergebnis aus dem Verhältnis- ist: -2785 2972 3296 3505 3775 3805 36o2 3336 3039 2889.Their modulus of elasticity had the values: E 1167 1201 1533 136o 1714 1587 1322 -1628 1395 1254. The result from the ratio- is: -2785 2972 3296 35 0 5 3775 38 0 5 36o2 3336 3 0 39 2889.

Diese Werte steigen also nach der Mitte des Resonanzbodens an und fallen dann wieder ab.So these values increase after the middle of the soundboard and then fall off again.

Die Erfindung kann sowohl auf den Resonanzboden als Ganzes als auch auf Teile, beispielsweise die Berippung, angewendet werden.The invention can be applied to the soundboard as a whole as well can be applied to parts such as the ribbing.

Durch die Erfindung wird mit Sicherheit und ohne weiteres eine große Gleichmäßigkeit in der Tongebung erzielt, die bisher nicht erreicht werden konnte.The invention certainly and easily makes a great one Uniformity in tone achieved, which could not previously be achieved.
