Description

Musikinstrument Das Hauptpatent 549 481 bezieht sich auf ein Musikinstrument, bei Odem Tonfolgen durch Frequenzänderung eines Röhrenoszillators erzeugt und die Frequenzänderungen mittels eines verstellbaren Widerstandes herbeigeführt werden. Ihm zufolge soll in den Stromkreis des Widerstandes eine Hilfsstromquelle geschaltet sein. Gemäß der Erfindung, die sich auf eine weitere Ausbildung des Gegenstandes des Hauptpatents bezieht, sollen die Hilfsstromquelle und der verstellbare Widerstand im Gitterkreis einer Oszillatorröhre liegen.Musical instrument The main patent 549 481 relates to a musical instrument, in breath tone sequences generated by changing the frequency of a tube oscillator and the Frequency changes can be brought about by means of an adjustable resistor. According to him, an auxiliary power source should be switched into the circuit of the resistor be. According to the invention, which relates to a further development of the article of the main patent refers to the auxiliary power source and the adjustable resistor lie in the grid circle of an oscillator tube.

Die Abbildung stellt eire Ausführungsbeispiel der Erfindung dar.The figure represents an embodiment of the invention.

Der Oszillator besteht aus der Röhre i mit der Anode 2, dem Gitter 3 und der Glühkathode 4., den Rückkopplungsspulen 5, 6, dem Abstimmungskondensator 7, der Anodenbatterie 8 und dem Heizakkumulator g. An das Gitter 3 ist der geradlinig langgestreckte Widerstand io angeschlossen. Die parallel zu ihm angeordnete Kontaktbahn i i zum Schließen und Öffnen des Widerstandsstromkreises ist mit der Kathode 4 verbunden. Zwischen dem Widerstand io und dem Gitter 3 ist ein kleiner Akkumulator 12 vorgesehen. Jedem Punkt der etwa aus einem gespannten Draht bestehenden Kontaktbahn i i entspricht, wenn er auf den Widerstand io herabgedrückt wird, ein Ton bestimmter Höhe.The oscillator consists of the tube i with the anode 2, the grid 3 and the hot cathode 4., the feedback coils 5, 6, the tuning capacitor 7, the anode battery 8 and the heating accumulator g. The grid 3 is straight elongated resistor connected io. The contact track arranged parallel to it i i for closing and opening the resistance circuit is connected to the cathode 4. A small accumulator 12 is provided between the resistor io and the grid 3. Each point of the contact path i i, which consists of a tensioned wire, corresponds, for example, when pressed down to resistance io, a sound of a certain pitch.

Das Musikinstrument gemäß der Erfindung ermöglicht, durch eine einzige einfache Bewegung jeden Ton innerhalb des zur Wiedergabe von Tonschöpfungen erforderlichen Tonhöhenbereichs ertönen zu lassen.The musical instrument according to the invention made possible by a single simple movement of each note within what is necessary to reproduce sound creations Pitch range.
