Description

  • Die vorliegende Erfindung betrifft eine Vorrichtung zum automatischen Stimmen eines Saiteninstrumentes nach dem Oberbegriff des Anspruchs 1. Sie betrifft ferner ein Verfahren zum automatischen Stimmen eines Saiteninstrumentes nach dem Oberbegriff des Anspruchs 9. The present invention relates to a device for automatic tuning of a string instrument according to the preamble of claim 1. It further relates to a method for automatic tuning of a string instrument according to the preamble of claim 9.
  • Das Stimmen von Instrumenten erfordert generell neben einem geübten Gehör eine Menge Zeit, die insbesondere von ungeübten, bspw. Hobby-Instrumentalisten, aufgebracht werden muß. The tuning instruments generally requires a trained ear next to a lot of time, which must be applied in particular by untrained, eg. Amateur instrumentalists. Bei dem klassischen Verfahren des Stimmens "von Hand" arbeitet der Musiker mit einer Stimmgabel, die durch Anschlagen den gewünschten Ton vorgibt und justiert durch Verändern der Saitenlänge bzw. Saitenspannung die Tonlage der jeweiligen Saite. In the classical method of tuning "by hand" of the musician works with a tuning fork, which sets by hitting the desired tone and adjusted by changing the string length and string tension, the pitch of each string. Durch Mehrfaches Anschlagen der Saite und der Stimmgabel wird das Ergebnis abgeglichen, bis die gewünschte Stimmung der Saite erreicht ist. the result is adjusted until the desired tuning of the string has been reached by repeatedly striking the string and the tuning fork. Ausgehend von dieser Stimmung werden dann die weiteren Saiten gestimmt. Starting from this mood the other strings are then tuned.
  • Da einesteils die Saiten der Instrumente wegen einer stets vorhandenen Nachgiebigkeit des Materials regelmäßig gestimmt werden müssen, die Saiten andernteils auch abhängig von den klimatischen Bedingungen in ihrer Länge veränderlich sind (eine Gitarrensaite dehnt sich auf der Bühne eines Konzertraumes mit der Hitze und feuchten Luft im Vergleich zu den Verhältnissen im vergleichsweise trockenen und kühlen Übungsraum aus), ist ein häufiges Stimmen erforderlich. partly since the strings of the instruments must be regularly voted for an ever-present resilience of the material, the strings are another partly dependent variable climatic conditions in length (a guitar string extends to the stage of a concert hall with the heat and humid air compared to the conditions in the relatively dry and cool practice room from), a common cast. Auch nach dem Aufziehen neuer Saiten müssen diese gestimmt werden. Even after the installation of new strings they must be tuned.
  • Um hier eine Erleichterung zu schaffen, wurde in der In order to create a relief here was in the US 4,803,908 US 4,803,908 eine Vorrichtung zum automatischen Stimmen eines Saiteninstrumentes vorgeschlagen, welches alle Merkmale des Oberbegriffs des Anspruchs 1 aufweist. proposed an apparatus for automatically tuning a stringed instrument, having all features of the preamble of claim 1. Bei dieser Vorrichtung werden an einer Gitarre mit einem dort "Strummer" genannten, im Korpus der Gitarre angeordneten Hilfsmittel alle Saiten gleichzeitig angeschlagen. In this apparatus, all the strings are struck simultaneously on a guitar with a where "Strummer" mentioned, arranged in the body of the guitar aids. Eine Elektronik erfaßt die Töne, vergleicht sie mit der Soll-Vorgabe und steuert eine an den Saiten angreifende Stelleinrichtung zur Verstellung der Saitenspannungen in der Weise, daß sie die vorgegebenen Töne treffen, an. An electronic system detects the sounds, compares it with the setpoint default value, and controls an attacking the strings adjusting device for adjusting the string tension in such a way that they meet the predetermined tones at.
  • Das System ist insoweit sehr zu begrüßen, als daß es ein zügiges und automatisches Stimmen ermöglicht und so insbesondere ungeübten Musikern, aber auch den Profis ein hohes Maß an Aufwand abnimmt. The system is so far very welcome, as it allows a rapid and automatic voices and so especially untrained musicians, but also the pros decreases a great deal of effort. Jedoch hat das System einen nicht unerheblichen Nachteil. However, the system has a significant disadvantage. Es ist insgesamt groß und klobig und erfordert erhebliche Veränderungen am Korpus der Gitarre, die einerseits einen Einfluß auf deren Akustik (Klang) und andererseits auf deren Handling (wegen des veränderten Gewichts) haben. It is generally large and cumbersome and requires substantial changes in the body of the guitar, which have on the one hand an influence on the acoustic (sound), and secondly their handling (because of the changing weight). Abgesehen davon, wird auch die Optik der Gitarre in nicht unerheblicher Weise verändert. Apart from that, even the look of the guitar is changed in significant ways.
  • Da die gesamte Gitarre den für die Klangeigenschaften maßgeblichen Resonanzkörper bildet, verändern sich auch die Klangeigenschaften, wenn dieser verändert wird. Since the entire guitar forms the decisive for the sound quality sound, also the sound characteristics change when it is changed. Damit ist das vorbekannte System in bestehende Instrumente nahezu nicht nachrüstbar, es kann aber auch nur schwer in neue Gitarren integriert werden. Thus the prior art system into existing instruments is almost can not be retrofitted, but it can also be difficult to integrate into new guitars. Insbesondere wären in klanglicher Hinsicht in der Planung zwei Gitarrentypen unabhängig voneinander zu entwickeln, eine Gitarre mit der vorbekannten Vorrichtung und eine ohne. In particular, two types of guitars were aurally in planning to develop independently, a guitar with the prior art device and one without.
  • In der In the WO 03/012774 A1 WO 03/012774 A1 ist eine elektronische Vorrichtung zum automatischen Stimmen einer Gitarre offenbart, welche eine Aufteilung von Komponenten auf den Kopf und den Korpus der Gitarre zeigt. is an electronic device for automatic tuning discloses a guitar, which provides a breakdown of components in the head and the body of the guitar. Bei dieser Vorrichtung ist zur Datenübertragung entweder eine Verkabelung der voneinander getrennten Komponenten vorgesehen, wobei dies einen massiven Eingriff in die Gitarre erfordert, mit allen oben geschilderten Folgen für den Gitarrenklang. In this apparatus for data transmission either a wiring of the separate components is provided, this requires a massive intervention in the guitar, with all the above mentioned effects on the guitar sound. Oder es ist eine Funk-, Infrarot oder sonstige drahtlose Übertragung vorgesehen. Or is it a radio, infrared or other wireless transmission provided. Hierzu muss allerdings an dem Kopf ein entsprechender Sender/Empfänger zusätzlich angebracht werden, welcher weiteres Gewicht mit sich bringt und die Optik wie auch das klangliche Verhalten der Gitarre stören kann. To this end, however, a corresponding transmitter / receiver must also be attached to the head, which brings further weight with it and can spoil the look as well as the sonic performance of the guitar. Ferner muss dieser Sender/Empfänger mit einer eigenständigen Energieversorgung versehen werden, dh am Kopf der Gitarre ist zusätzlich eine Batterie oder gar ein Zuleitungskabelanschluss vorzusehen. Further, this transmitter / receiver must be provided with an independent power supply, that is on the headstock additionally provide a battery or even a lead cable connector.
  • Von der geschilderten Problematik geht die Erfindung aus. Of the problems described, the invention is based. Sie hat zur Aufgabe, eine insoweit verbesserte Vorrichtung anzugeben, die in ein Instrument, insbesondere eine Gitarre, mit minimaler Beeinflussung der Klangeigenschaften und mit möglichst wenigen und kleinen Elementen integriert werden kann. It has for its object to provide an improved apparatus so far, which can be integrated into an instrument, particularly a guitar with minimal impact on the sound quality and with as few and small elements. Ferner soll ein Verfahren zum automatischen Stimmen eines Saiteninstrumentes angegeben werden, welches diesen Vorgaben genügt. Further, a method for automatic tuning of a string instrument is to be provided which satisfies these requirements.
  • Zur Lösung dieser Aufgabe wird eine Vorrichtung mit den Merkmalen des Schutzanspruchs 1 vorgeschlagen. To achieve this object a device having the characteristics of claim 1 is proposed. Ein Verfahren, welches diese Aufgabe löst, ist in Anspruch 9 angegeben. A method which solves this object is defined in claim. 9
  • Die Ansprüche 2 bis 8 und 10 bis 11 enthalten vorteilhafte Weiterbildungen der Vorrichtung bzw. des Verfahrens. The claims 2 to 8 and 10 to 11 contain advantageous developments of the device and the method.
  • Kerngedanke der Erfindung ist es, die Komponenten der Vorrichtung (die so gesehen auch als System bezeichnet werden kann) auf dem Instrument zu verteilen. The core idea of ​​the invention is that components of the device (which can be seen as also referred to as system) to be distributed on the instrument. Bei einer Gitarre bspw. wird nicht die gesamte Vorrichtung im Korpus angeordnet. In a guitar, for example., The entire device is not arranged in the corpus. So bietet der Kopf bzw. Hals auch, wenn auch nur wenig, Raum, für die (dezente) Anbringung weiterer Komponenten. So the head or neck also, if only little space for the (discreet) attachment of other components. Insbesondere kann dabei auf ohnehin bei Gitarren am Kopf angeordnete Mittel zum Verstellen der Saitenlänge bzw. -spannung zurückgegriffen werden, was den Einsatz von Spezialteilen reduziert. In particular, can be resorted to already arranged for guitar head means for adjusting the string length or voltage thereby, reducing the use of special parts. Insgesamt müssen in das Instrument, bspw. die Gitarre, weniger zusätzliche Komponenten eingebracht werden. Overall, the guitar, fewer additional components must be incorporated into the instrument, for example..
  • Um die Trennung der Komponenten Steuerung und Antrieb ohne tief greifende Eingriffe in den Instrumentenkörper vornehmen zu können, werden erfindungsgemäß die Steuersignale zwischen der an einem Instrumententeil sitzenden Steuerung und dem wenigstens einen Antrieb über wenigstens eine als Busleitungen dienende Saite der Gitarre geführt. In order to make the separation of the components of the control and drive without far-reaching intervention in the instrument body, the control signals between the seated on an instrument part controller and the at least one drive via at least one serving as bus lines string of the guitar are performed according to the invention.
  • Die Saiten von Saiteninstrumenten bestehen in vielen Fällen aus einem leitenden Material (Metall) oder sind von einem Faden aus einem solchen umwickelt. The strings of stringed instruments made in many cases made of a conductive material (metal) or are wrapped by a thread made of such a material. Alternativ können sie, wenn der Klang es zulässt, mit einem leitenden Material beschichtet sein. Alternatively, they may, when the sound permits, be coated with a conductive material. Diese Lösung spart den Einsatz weitere Leitungen, die in dem Instrumentenkörper verlegt werden müssten. This solution saves the use of additional lines that would have to be transferred to the instrument body. Neben den Klangeigenschaften bleibt daher nicht zuletzt auch die Optik des Instrumentes erhalten. In addition to the sound quality, therefore, not least the appearance of the instrument is maintained. Damit, wenn mehrere Saiten als Leiter genutzt werden sollen, diese nicht untereinander elektrisch kurzgeschlossen sind, müssen Elemente, über die die Saiten gemeinsam geführt werden (bspw. der Steg bei einer Gitarre) so ausgebildet sein, daß sie die Saiten gegeneinander isolieren. Thus, if several strings are to be used as a guide, they are not each other electrically shorted elements (the web, for example. At a guitar) have, over which the strings are jointly be adapted to isolate the strings up to today. Dazu können diese Elemente aus einem nicht leitenden Material (bspw. Keramik) gefertigt oder mit einem solchen beschichtet sein, oder es müssen sonstige Vorkehrungen der Isolierung getroffen sein (bspw. zwischen geordnete Isolierscheiben etc.). For this purpose, these elements can be manufactured or coated with such a non-conductive material (eg. ceramic), or have other arrangements of the insulation made (eg. intermediate insulating etc.).
  • Der Antrieb kann ein Motor, bspw. Elektromotor, sein, er kann aber auch pneumatisch oder hydraulisch arbeiten. The drive can be a motor, for example. Electric motor, but it can also operate pneumatically or hydraulically.
  • Wenn das Instrument ein auf elektrischem Wege mit einem Verstärker verbundenes Instrument ist (z. B. eine E-Gitarre), so kann ein ohnehin bereits vorhandener und an den Verstärker angeschlossener Tonabnehmer des Instrumentes als (Teil der) Erfassungseinheit genutzt werden. When the instrument is a connected to electrical means comprising an amplifier instrument (z. B. an electric guitar), so an already existing and connected to the amplifier pickup of the instrument can be used as (part of) the detection unit.
  • Wenn wie in einer Weiterbildung nach Anspruch 2 auch die Stromversorgung für den mindestens einen Antrieb über wenigstens eine der Saiten geführt ist, muß auf der Seite des Antriebs keine eigene Stromversorgung (Batterie o.ä.) bereitgestellt werden, was zu einem zusätzlichen Bauteil mit allen negativen Folgen für die Optik und die Balance des Instrumentes führen würde, und es muß auch keine gesonderte Versorgungsleitung verlegt werden, was zu den oben bereits genannten Nachteilen führen würde. If the power supply for the at least one drive one of the strings is performed as in a further development according to claim 2 on at least, must be provided on the side of the drive not have their own power supply (battery, etc.), which all in an additional component with negative consequences for the optics and the balance of the instrument would result, and it must also be laid no separate supply line, which would lead to the disadvantages already stated above.
  • Durch eine wie in Anspruch 3 angegebene Ausgestaltung der Steuerung kann diese in einfacher Weise durch Anschlagen einer seite angesprochen werden. By a specified in claim 3 embodiment of this control can be addressed in a simple manner by striking one side.
  • Eine Schnittstelle, wie sie gemäß Anspruch 4 vorgesehen sein kann, gibt die Möglichkeit, von außen - auch nachträglich - eine Software in die Vorrichtung einzuspeisen. An interface, such as may be provided in accordance with claim 4, is the possibility of outside - even subsequently - to feed a software in the device. Ferner können über die Schnittstelle verschiedene Referenzstimmungen in die Speichereinrichtung eingegeben werden, um das Instrument nach unterschiedlichen Schemata stimmen zu können. Furthermore, different reference scenes can be entered into the storage device via the interface, to tune the instrument according to various schemes.
  • Eine wie in Anspruch 5 vorgeschlagene Ausgestaltung der Vorrichtung erlaubt ein saitenweises Stimmen des Instrumentes. A proposed as in claim 5 embodiment of the device allows a string-wise tuning of the instrument. Es kann ebenso gut auch ein Antrieb verwendet werden, der durch entsprechende Getriebe oder ähnliche Vorrichtungen zum Verstellen jeweils einer Saite schaltbar ist. It can be used as well, a drive which is switchable by means of appropriate gear, or similar devices for moving each of a string.
  • Ist die Vorrichtung wie in Anspruch 6 angegeben gebildet, ergibt sich ein besonders kompakter Aufbau. The apparatus as stated in claim 6 are formed, results in a particularly compact structure. Werden die einzelnen Komponenten möglichst klein gewählt, "verschwinden" sie nahezu im Gesamteindruck des Instrumentes und stören den Musiker auch nicht beim Spiel desselben. If the individual components as small as possible, "disappear" they do not even nearly the same in the overall impression of the instrument and interfere with the musicians at play. Zudem ist es nicht erforderlich, beim Stimmen des Instrumentes externe Komponenten hinzuzuziehen, der Musiker kann sein Instrument praktisch überall und nahezu unabhängig stimmen. Moreover, it is not necessary to call in external components for tuning the instrument, the musician can be an instrument virtually anywhere and virtually independent vote.
  • Eine Weiterbildung der Vorrichtung nach Anspruch 7 ergibt ein redundantes System. A development of the device according to claim 7 provides a redundant system. Die Vorrichtung kann auch bei Defekt einer Saite noch weiter zum Stimmen des Instrumentes betrieben werden. The device can also be operated in case of failure of a string continue to tune the instrument.
  • In Anspruch 8 ist eine bevorzugte Ausgestaltung der Vorrichtung zur Integration in einer E-Gitarre angegeben. In Claim 8 a preferred embodiment of the device for integration in an electric guitar indicated.
  • Das Verfahren nach Anspruch 9 stellt, wie oben bereits gesagt eine Lösung der oben genannten Aufgabe hinsichtlich eines Verfahrens dar. Es kann bevorzugt mit einer Vorrichtung nach einem der Ansprüche 1 bis 8 betrieben werden, ist jedoch nicht auf eine solche Vorrichtung beschränkt, wobei gemäß dem erfindungsgemäßen Verfahren die Saiten des Instrumentes als Busleitungen verwendet werden können. The method of claim 9 illustrates, as already said, a solution of the above-mentioned object relating to a method. It can preferably be operated with a device according to one of claims 1 to 8, but is not limited to such a device, according to the methods of the invention, the strings of the instrument can be used as bus lines. Dadurch müssen keine gesonderten Kabel oder sonstigen Übertragungsmittel (Funk, Infrarot) installiert werden. Thus, no separate cable or other transmission medium (radio, infrared) must be installed.
  • Eine wie in einer Weiterbildung des Verfahrens nach Anspruch 10 geforderte Aufbereitung des ersten digitalen Signals kann sinnvoll sein, um aus diesem Signal zuverlässig eine Tonlage bestimmen zu können. A required as in a development of the method according to claim 10 processing the first digital signal may be useful in order to determine from this signal a reliable pitch.
  • Eine Bestimmung der Grundfrequenz (Tonlage) des ersten digitalen Signals erfolgt vorzugsweise unter Zuhilfenahme eines mathematischen Frequenzfilters (Anspruch 11). A determination of the fundamental frequency (pitch) of the first digital signal is carried out preferably with the aid of a mathematical frequency filter (claim 11). Dieser erlaubt im Gegensatz zu dem ansonsten gebräuchlichen Verfahren der Fast Fourier Transformation (FFT) eine schnellere und genauere Frequenzbestimmung aus nur einem Anschlag der Saite. This allows, in contrast to the otherwise customary method of the Fast Fourier Transformation (FFT), a faster and more accurate determination of frequency of one stop of the string. Dies ist wichtig, da bei nur einem Anschlag der Saite die Obertöne, die für eine exakte Bestimmung der Tonlage (Frequenz) erfaßt werden müssen, sehr schnell abklingen. This is important because with only one stop of the string subside overtones that an exact determination of the pitch (frequency) must be detected very quickly.

It can be used equally well for acoustic guitars, electric bass, or other electrical or electro-acoustic or acoustic stringed instruments such as violins, harps, etc..
  • In den In the Figuren 1 bis 4 Figures 1 to 4 ist in verschiedenen, teilweise vergrößerten Ansichten eine E-Gitarre 1 gezeigt, die mit einer erfindungsgemäßen Vorrichtung versehen ist. an electric guitar 1 is shown in several, partly enlarged views, which is provided with an inventive device. Die E-Gitarre 1 läßt sich grob unterteilen in den Korpus 2, den Steg 3 und den Kopf 4. Am Korpus sind an dem sogenannten Tremolo-Systemblock 5 die Saiten 6a - 6f mit ihren ersten Enden (ball ends) befestigt und nebeneinander über den Steg 3 bis zum Kopf 4 gespannt, wo sie mit ihren zweiten Enden auf Wirbeln 7 aufgewickelt und verstellbar festgelegt sind. The electric guitar 1 can be roughly divided into the body 2, the web 3 and the head 4. The strings 6a are on the body of the so-called tremolo system block 5 - 6f with their first ends (ball ends) attached to and adjacent to each other on the web where they are stretched to 3 to head 4, wound with their second ends on vertebrae 7 and adjustably fixed. Die Wirbel 7 sind mechanisch mit Flügeln 8 verbunden, so daß durch Drehen der Flügelt 8 das Saitenende auf den Wirbel 7 auf- oder von dieser abgewickelt werden kann. The pegs 7 are mechanically connected with wings 8, so that the string end up by rotating the wing t 8 to the vertebra 7 or can be unwound therefrom. Dadurch wird die Spannung bzw. Länge der Saite verändert und die Gitarre gestimmt. Characterized the tension or length of the string is modified and tuned the guitar.
  • In In Figur 1 Figure 1 ist zudem ein sogenanntes Pick-Guard 9 zu erkennen, welche eine Art Abdeckplatte ist und unter der im Korpus 2 ein Raum geschaffen ist, in welchem die Elektronik der E-Gitarre 1 angeordnet ist. 9 is also seen, which is a kind of cover plate and at which a space is provided in the body 2, in which is located the electronics of the electric guitar 1 a so-called pick-Guard. Unterhalb dieses Pick-Guards 9 ist ein zu der erfindungsgemäßen Vorrichtung gehöriger Steuerchip angeordnet, der in Below this pick-Guards 9 associated to a device of the invention control chip is located in the Fig. 2 Fig. 2 schematisch mit 10 angedeutet ist. is schematically indicated by 10.

So sind bspw. die auf dem Korpus 2 unterhalb der Saiten 6a bis 6f sitzenden Tonabnehmer (Pickups) 12 zu erkennen, die die Schwingungen der Saiten (und damit den durch Anschlagen derselben erzeugten Ton) in ein elektrisches Signal umwandeln. Thus, for example, on the body 2 below the strings 6a-6f seated pickup (pickups) to detect 12, the vibrations of the strings (and thus the same sound produced by striking) converted into an electrical signal. Diese Tonabnehmer 12 dienen zugleich in später noch zu erläuternder Weise als Bestandteil der erfindungsgemäßen Vorrichtung. These pickups 12 serve at the same time in to be explained later, as a component of the inventive device.
  • Ferner ist in diesen Darstellungen ein Potentiometer 13 dargestellt. Further, in these illustrations, a potentiometer 13 is shown. In der Regel verfügen E-Gitarren über mehrere derartige Potentiometer zum Einstellen der Höhen, Bässe und der Lautstärke. Usually electric guitars have more than one such potentiometer to adjust the treble, bass and volume. Hier ist das dargestellte Potentiometer 13 der Lautstärkeregler. Here, the potentiometer shown is 13, the volume control. Dieser spezielle Regler ist zur Integration der erfindungsgemäßen Vorrichtung in die E-Gitarre 1 nicht als herkömmliches Potentiometer ausgeführt, sondern als sogenanntes Push-Pull Potentiometer, welches eine zusätzliche Schaltfunktion aufweist. This special control is not executed for the integration of the inventive device in the electric guitar 1 as a conventional potentiometer, but as a so-called push-pull potentiometer which has an additional switching function.
  • Schließlich sind in diesen Figuren noch die von dem Steuerchip zu dem Tremolo-Systemblock 5, genauer zu den Saiten 6a bis 6f führenden Leitungen 14 zu erkennen.

Recess shown on the right used. Da die Reiter 15 und die Reitereinsätze 16 bei einer E-Gitarre 1 regelmäßig aus Metall und damit aus einem leitenden Material bestehen, müssen, um einen Kurzschluß zwischen den über die Leitungen 14 elektrisch kontaktierten Saiten zu vermeiden die Reitereinsätze 16, über die die Saiten 6a bis 6f laufen, gegeneinander isoliert sein. Since the rider 15 and the rider inserts 16 regularly consist in an electric guitar 1 of metal and of a conductive material, must in order to avoid a short circuit between the via lines 14 electrically contacted strings, the rider inserts 16, over which the strings 6a run to 6f, be insulated from each other. Zu diesem Zwecke sind die in are for this purpose in Fig. 5(a) Fig. 5 (a) mit 21 bezeichneten Flächen isoliert. 21 designated areas isolated.
  • In den In the Figuren 7(a) bis 7(d) Figures 7 (a) to 7 (d) sind noch einmal Einzelheiten des Kopfes 4 der E-Gitarre 1 mit den daran angeordneten Komponenten der erfindungsgemäßen Vorrichtung zu erkennen, wobei are once again details of the head 4 of the electric guitar 1 to detect with the attached components of the device according to the invention, wherein Fig. 7(d) Fig. 7 (d) eine Detailvergrößerung des in an enlarged detail of the in Fig. 7(c) Fig. 7 (c) mit D bezeichneten Bereichs darstellt. represents D designated area.
  • In den In the Figuren 8(a) bis 8(d) Figures 8 (a) to 8 (d) sind die mechanischen Einheiten zum Verstellen der Saitenspannung bestehend aus den Wirbeln 7, den Flügeln 8 und den Stellmotoren 11 noch einmal losgelöst von dem Kopf 4 dargestellt. the mechanical units for adjusting the string tension consisting of the vertebrae 7, the wings 8 and the actuators 11 once detached from the head 4 are shown. Zu erkennen ist, daß alle diese Einheiten auf einer gemeinsamen Platine 22 sitzen, die weitere Steuerelemente zur Ansteuerung der Stellmotoren 11 enthält. It can be seen that all these units mounted on a common circuit board 22 which contains additional controls for controlling the servomotors. 11 Über die metallischen und damit leitenden Wirbeln 7 sind die Saiten elektrisch mit entsprechenden Leiterbahnen auf der Platine 22 verbunden. Via the metallic and thus conductive vertebrae 7, the strings are electrically connected to corresponding circuit traces on the board 22nd
  • Die erfindungsgemäße Vorrichtung zum automatischen Stimmen der E-Gitarre 1 arbeitet wie folgt: The inventive apparatus for automatic tuning of the electric guitar 1 operates as follows:
  • Durch Ziehen des Push-Pull Potentiometers 13 wird das System aktiviert. the system is activated by pulling the push-pull potentiometer. 13 Hierzu wird auf eine in For this purpose, an in Figur 9 Figure 9 dargestellte Schaltung zurückgegriffen, die nachfolgend noch zu beschreiben sein wird. which is still to be described hereinafter resorted circuit shown.
  • Dem Steuerchip 10 können nun durch Anschlagen einer der Saiten Befehle erteilt werden. The control chip 10 can now be issued by striking a string commands. Die durch Anschlagen der Saiten erzeugten Töne werden durch die Tonabnehmer 12 in ein elektrisches Signal gewandelt, welches in der Steuerung auf eine Frequenz hin umgerechnet wird. The tones generated by striking the strings are converted by the pickup 12 into an electric signal, which is down converted in the controller to a frequency. In der Steuerung sind bestimmte vorprogrammierte Befehle abgelegt, die auf eine innerhalb einer bestimmten Toleranz liegenden Frequenz hin aufgerufen werden. In the control of certain pre-programmed instructions are stored, which are called a lying within a certain tolerance toward frequency. Auf diese Weise kann bspw. das Programm zum Stimmen einer der Saiten, z. In this way, for example, can. The program for tuning a string, eg. B. der e-Saite 6f, aufgerufen werden. As the e-string 6f, are called. Ist das Programm aktiviert, lädt der Steuerchip aus einem Speicher eine Referenzfrequenz für diese Saite, die als Soll-Frequenz dient. If the program is activated, the control chip loads from a memory a reference frequency for that string, which serves as the target frequency. Die Saite wird nun gegebenenfalls erneut angeschlagen, die Ist-Frequenz aus dem durch die Tonabnehmer 12 umgewandelten Signal in dem Steuerchip 10 errechnet und über die als Busleitungen genutzten Saiten ein Signal an die Platine 22 bzw. über diese an den entsprechenden Stellmotor 11 zum Verstellen der Saitenspannung zum Erreichen der Soll-Frequenz geschickt. The string is then optionally struck again, the actual frequency from the converted by the pickup 12 signal calculated in the control chip 10 and the used as bus lines strings a signal to the circuit board 22 and through them to the respective servo motor 11 for adjusting the sent string tension to achieve the desired frequency. Dabei überwacht der Steuerchip 10 die Veränderung der Frequenz und gibt bei Erreichen der Soll-Frequenz ein Stop-Signal an den Stellmotor 11. Auf diese Weise können alle Saiten nacheinander gestimmt werden. Here, the control chip 10 monitors the change in frequency and, upon reaching the target rate a stop signal to the servo motor 11. In this way, all the strings are tuned one by one. Als Routine zum Errechnen der Ist-Frequenz aus dem elektrischen Signal der Tonabnehmer wird ein mathematisches Frequenzfilter eingesetzt, da dieses besonders schnell und zuverlässig die Frequenz errechnen kann. As a routine for calculating the actual frequency of the electrical signal of the pickup a mathematical frequency filter is used, as this can quickly and reliably calculate the frequency.
  • Über eine in den Figuren nicht dargestellte Schnittstelle können dem Steuerchip 10 verschiedene Frequenzvorgaben für die Saiten gegeben werden, je nachdem welche Art der Stimmung gerade gewählt werden soll (bspw. open tuning etc.). A not illustrated in FIGS interface 10 different frequency requirements for the strings can be given to the control chip, depending on what kind of mood is about to be selected (for example, open tuning, etc.).
  • Für die Übertragung der Steuersignale werden lediglich zwei der Saiten benötigt. two of the strings are only required to transmit the control signals. Über zwei weitere Saiten, hier die Saiten 6f (tiefe e-Saite) und 6e (a-Saite) wird die Spannungsversorgung für die Platine 22 und die Stellmotoren 11 in den Kopf 4 verbracht, so daß eine eigene Spannungsquelle dort nicht benötigt wird. Two other strings, here, the strings 6f (low E string) and 6e (a string), the voltage supply for the board 22 and the servomotors is spent 11 in the head 4, so that a separate power source is not required there. Die Saiten 6f und 6e werden zum Übertragen der Spannung gewählt, da die tiefe e-Saite und die a-Saite die dicksten Saiten der E-Gitarre 1 sind und damit am seltensten reißen. The strings 6f and 6e are selected for transmitting the voltage as the deep e-string and a string are the thickest strings of the electric guitar 1 and thus least likely to tear. Von den verbleibenden vier Saiten 6a bis 6d können von dem Steuerchip 10 jeweils zwei beliebige als Busleitungen frei angesteuert werden. Of the remaining four strings 6a to 6d, any two of the control chip 10 can be controlled freely as bus lines. Auf diese Weise ist das System redundant und kann auch noch bei einer oder sogar zwei gerissenen Saiten der Saiten 6a bis 6d arbeiten. In this way the system is redundant and can also operate at one or even two broken strings the strings 6a-6d.
  • Leuchtdioden auf dem Korpus 2, bspw. im Bereich der Tonabnehmer 12 unterhalb der Saiten 6a bis 6f können den Zustand des Steuerchips 10 bzw. des Programmablaufs anzeigen und so die Handhabung der Vorrichtung vereinfachen. Light emitting diodes on the body 2, for example. In the area of ​​the pickup 12 below the strings 6a to 6f can view the state of the control chip 10 and the program sequence and thus facilitate handling of the device. Auch kann hier eine "Kurzanleitung" aufgebracht sein, z. It can also be applied here, a "Quick Start Guide" z. B. mit der Anzeige, durch Anschlagen welcher der Saiten 6a bis 6f in welchem Ton welche Befehle aufgerufen werden. As with the display, in which clay which commands are invoked by hitting which the strings 6a-6f. Die den Befehlen zugeordneten Frequenzen können von dem Steuerchip 10 so verwaltet werden, daß sie der aktuellen Stimmung der E-Gitarre angepaßt sind, das heißt, daß der Benutzer stets dieselbe Saite mit dem selben Griff anschlagen muß, um einen Befehl abzurufen, egal, wie die Gitarre und damit die Saite gerade gestimmt ist. The assigned commands frequencies can be managed from the control chip 10 so as to match the current mood of the electric guitar, which means that the user must always strike the same string with the same handle to fetch an instruction, no matter how the guitar and the string has just voted.
  • Die Spannungsversorgung des Systems erfolgt in diesem Ausführungsbeispiel extern und zwar über das Verstärkerkabel, mit dem die Gitarre ohnehin an einen Verstärker elektrisch angeschlossen ist. The power supply of the system is done in this embodiment, externally and via the amplifier cable with which the guitar is already electrically connected to an amplifier. Die in In the Fig. 9 Fig. 9 dargestellte Tonaderschaltung überwacht ständig den Innenwiderstand der E-Gitarre 1. Dieser liegt bei normal spielbereiter E-Gitarre 1 hoch. Tonaderschaltung shown continuously monitors the internal resistance of the electric guitar 1. This is normal game-ready electric guitar 1 high. Zieht nun der Musiker das Push-Pull Potentiometer 13, so koppelt der die Tonabnehmer 12 von der Klinkenbuchse für das Verstärkerkabel und damit vom Verstärker ab und schaltet den Steuerchip 10 zu. then musician pulls the push-pull potentiometer 13, so couples of the pickup 12 of the jack for the amplifier cable and thus from the amplifier and switches on the control chip 10 to. Dadurch sinkt der Innenwiderstand der E-Gitarre 1 wenigstens um einen Faktor 20 ab. Thus, the internal resistance of the electric guitar 1 decreases by at least a factor of 20th Dies erkennt die Schaltung und schaltet das Verstärkerkabel zum einen von dem Verstärker ab, damit die E-Gitarre 1 "stumm" gestimmt werden kann. This recognizes the circuit and switches the amplifier cable to one of the amplifier, so that the electric guitar can be tuned one "dumb". Ferner schaltet die Schaltung eine Versorgungsspannung, die sie bspw. von dem Netzteil des Verstärkers, aber auch einem externen Netzteil gewinnen kann auf das Verstärkerkabel. Furthermore, the circuit switches a supply voltage that they can win, for example. Of the power supply of the amplifier, and also an external power supply to the amplifier cable. Diese Spannung wird dann der Steuerung 10 zugeführt und über die Saiten 6e und 6f in den Kopf 4 weitergeleitet. This voltage controller 10 is then supplied to and 6e over the strings and forwarded in the head 4 6f. Nun kann die erfindungsgemäße Vorrichtung arbeiten. the inventive device can now work. Nach Beendigung des Stimmens oder bspw. des Einrichtens der Schaltung oder des Aufbringens neuer Daten schaltet der Musiker das Push-Pull Potentiometer 13 zurück in die Normalstellung. After completion of tuning or, for example, and setting of the circuit or the application of new data of the musicians on the push-pull potentiometer 13 back into the normal position. Der Innenwiderstand der E-Gitarre 1 steigt durch die nun wieder an das Verstärkerkabel angeschlossenen Tonabnehmer 12 wieder an. The internal resistance of the electric guitar 1 increases by the now back to the amplifier cable connected pickup 12 again. Dies erkennt die Tonader Schaltung gemäß This recognizes the audio conductor circuit according Fig. 9 Fig. 9 und gibt die Signale aus dem Verstärkerkabel wieder auf den Verstärker, der Musiker kann weiterspielen. and outputs the signals from the amplifier cable back to the amplifier, the musician can continue playing.
