KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Gegenstand vorliegender Erfindung ist ein Resonanzkasten im Sockel von Pianino's, durch welchen eine Verstärkung und Veredelung des Tones bezweckt wird.The present invention is a resonance box in the base of Pianino's, through which are intended to strengthen and refine the clay. Wie aus beiliegender Zeichnung in Fig. 1 und 2 ersichtlich, ist derselbe im unteren Theil des Pianino's angeordnet und bildet gleichzeitig den Boden des Instrumentes. Er besteht im wesentlichen aus einem den unteren Dimensionen des Instrumentes angepafsten und nach der Länge der Saiten berechneten Kasten A aus dünnwandigem Resonanzholz. Die obere Decke a\ der eigentliche Resonanzboden,1 ist leicht gewölbt, nach seinen Kanten zu abgeflacht und mit Rippen r versehen. Der Resonanzboden a1 wird durch Vermittelung des Grundkörpers des Pianino's (der Rast und des Umbaues) in Schwingungen versetzt, so dafs die unter ihm befindliche Luft ebenfalls in Schwingungen geräth und den Boden a2 mitschwingen läfst. Aufser dieser Beeinflussung des Resonanzbodens al erfolgt eine solche auch durch die in den Raum s hineingeworfenen, auch nach unten wirkenden Schallwellen. As can be seen from the accompanying drawing in FIGS. 1 and 2, it is arranged in the lower part of the pianino and at the same time forms the base of the instrument. It essentially consists of a box A made of thin-walled resonance wood, adapted to the lower dimensions of the instrument and calculated according to the length of the strings. The upper ceiling a \ the actual soundboard, 1 is slightly arched, flattened towards its edges and provided with ribs r . The soundboard a 1 is made to vibrate through the intermediary of the main body of the pianino (the rest and the conversion), so that the air below it also starts to vibrate and makes the floor a 2 vibrate. In addition to this influencing of the soundboard a l, it is also effected by the sound waves thrown into the room s , which also act downwards. Es ist ersichtlich, dafs durch die wesentlich vergröfserte Resonanz und die eigenthümliche Mitwirkung derselben der Ton des Instrumentes in abgerundeter Fülle und Verstärkung zur Geltung kommt.It can be seen that through the substantially increased resonance and the peculiar Contribution of the same to the tone of the instrument in rounded fullness and amplification Comes into play. Die Wirkung der Einrichtung wird nur minder stark, jedoch nicht im Wesen verändert, wenn der untere Boden α2 des Resonators in Wegfall kommt.The effect of the device is only less strong, but not essentially changed, if the lower bottom α 2 of the resonator is omitted. Patent-Anspruch:Patent claim: Ein waagerechter Resonanzkasten (A) für Pianino's, dadurch gekennzeichnet, dafs derselbe im Sockel des Instrumentes angeordnet ist, und dafs dessen event, leicht gewölbte Decke (al) durch Vermittelung der Rast und des Umbaues des Pianinokörpers, sowie durch die Schallwellen im Raum s zum Mitschwingen gebracht wird.A horizontal resonance box (A) for pianinos, characterized in that it is arranged in the base of the instrument, and that its possibly slightly curved top (a l ) by means of the rest and the reconstruction of the pianino body, as well as by the sound waves in the room s is made to resonate.
