Abstract

By pressing on a key (11), the slide valve (2) of the sand container (1) is opened via an angle piece (12). As a result, sand falls through the guide lamellae (3) onto the strings (4) which have been strung in threes. Owing to the falling weight, these strings are made to vibrate. The sand falls further into a sand discharge (13). The vibrations caused by the impact of the sand particles on the strings (4) are transferred, via two webs (7), onto two separate resonance floors (5) or spaces and rendered audible and usable for music-making. <IMAGE>

PATENTANSPRÜCHEPATENT CLAIMS 1. Verfahren zur musikalischen Tonerzeugung, dadurch gekennzeichnet, dass körniges Material auf schwingungsfähige Körper fallen gelassen wird, wodurch diese Körper zum Schwingen gebracht werden.1. A method for musical tone generation, characterized in that granular material is dropped on vibrating body, whereby these bodies are made to vibrate. 2. Vorrichtung zur Durchführung des Verfahrens gemäss Anspruch 1, dadurch gekennzeichnet, dass schwingungsfähige Körper vorgesehen sind, die im Bereich des Fallweges des körnigen Materials angeordnet sind.2. Device for carrying out the method according to claim 1, characterized in that oscillatable bodies are provided which are arranged in the area of the fall path of the granular material. 3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, dass die schwingungsfähigen Körper gespannte Saiten, Trommelfelle, bearbeitete Hölzer, Metallplatten oder Glaskörper sind.3. Device according to claim 2, characterized in that the oscillatable bodies are tensioned strings, eardrums, machined wood, metal plates or glass bodies. 4. Vorrichtung nach Anspruch 3, dadurch gekennzeichnet, dass das körnige Material aus Sand, Glaskügelchen oder Metallkügelchen besteht.4. The device according to claim 3, characterized in that the granular material consists of sand, glass beads or metal beads. Die vorliegende Erfindung bezieht sich auf ein Verfahren und auf eine Vorrichtung zur musikalischen Tonerzeugung.The present invention relates to a method and apparatus for musical tone generation. Bei einer bekannten Vorrichtung zur musikalischen Tonerzeugung, beispielsweise bei einem Klavier, wird durch Niederdrücken einer Taste über eine Mechanik einen Hammer mit einem bestimmten Gewicht gegen eine Saite geschlagen.In a known device for musical tone generation, for example in a piano, a hammer with a specific weight is struck against a string by a mechanism by depressing a key. Die vorliegende Erfindung ersetzt diesen Hammer durch fallendes körniges Material. Hiezu ist das Verfahren und die Vorrichtung zur musikalischen Tonerzeugung durch die Merkmale der Ansprüche 1 und 2 gekennzeichnet.The present invention replaces this hammer with falling granular material. For this purpose, the method and the device for musical tone generation are characterized by the features of claims 1 and 2. Das Verfahren und die Vorrichtung werden nachfolgend anhand eines Ausführungsbeispieles umschrieben.The method and the device are described below using an exemplary embodiment. In den Figuren zeigen:In the figures show: Figur 1 eine Draufsicht einer Vorrichtung zur Tonerzeugung undFigure 1 is a plan view of a tone generating device and Figur 2 eine Seitenansicht, teilweise im Schnitt, der Vorrichtung gemäss Figur 1.Figure 2 is a side view, partially in section, of the device of Figure 1. Ein Sandbehälter 1 weist an der Unterseite Öffnungen (pro Ton eine Öffnung) auf, die durch ein einfaches Schiebe-yentil 2 verschlossen sind. Durch Tastendruck 11 können die Öffnungen freigegeben werden.A sand container 1 has openings on the underside (one opening per tone), which are closed by a simple sliding valve 2 . The openings can be released by pressing button 11. Durch Druck auf die Taste 11 wird über ein Winkelstück 12 das Schiebeventil 2 eines Sandbehälters 1 geöffnet. Dadurch fällt Sand durch die Führungslamellen 3 auf die Saiten 4, attackiert diese zum Schwingen, und fällt weiter in einen Sand-Sammelbecken 13.By pressing the button 11, the sliding valve 2 of a sand container 1 is opened via an elbow 12. As a result, sand falls through the guide lamellae 3 onto the strings 4, attacks them to vibrate, and falls further into a sand collection basin 13. Die Saiten sind an einem Anhangstift 10 und an einem Stimmwirbel 9 befestigt.The strings are attached to an attachment pin 10 and a tuning peg 9 . Die Schwingungen, hervorgerufen durch das Aufprallen der Sandkörner auf die Saiten, werden über zwei Stege 7 auf zwei Resonanzböden 5 bzw. Resonanzräume übertragen und dadurch hörbar und musikalisch verwendbar gemacht. Die Fallhöhe der Sandkörner ist durch den Abstand A-B gegeben.The vibrations caused by the impact of the grains of sand on the strings are transmitted via two bridges 7 to two soundboards 5 or resonance chambers and are thus made audible and musically usable. The height of fall of the sand grains is given by the distance A-B. Die mechanischen Teile der Vorrichtung sind durch eine Abdeckung 6 geschützt.The mechanical parts of the device are protected by a cover 6. 22 55 1010 ISIS 2020 2525 3030 3535 4040 4545 5050 5555 «0«0 6565 SS 2 Blatt Zeichnungen2 sheets of drawings
