Abstract

The invention relates to an arrangement of sound pick-ups and loudspeakers, in particular for E-guitars, with a rectangular arrangement of at least 2 loudspeakers and 4 or 6 sound pick-up pairs. In conventional electrodynamic activation of the amplifiers, it is rarely possible to reproduce the sound stimulus of the strings in an adequate manner. The proposed solution is intended to correct these system-related shortcomings even before they occur so that unnecessarily complex compensation measures subsequently implemented are not required.

Description

Elektrodynamischer Tonabnehmer zur Erfassung der Saitenschwingung in 2 Ebenen, ergänzbar durch 2-kanalige, phasentreue Übertragerkette und Lautsprecheranordnung, für elektrisch verstärkte Musikinstrumente.Electrodynamic pickup to capture the String vibration in 2 levels, can be supplemented by 2-channel, phase-accurate transformer chain and Speaker arrangement, for electrically amplified Musical instruments.

Die Erfindung betrifft einen Tonabnehmer mit dazu passenen Endwandlern nach dem Oberbegriff des Anspruchs 1 und den Unteransprüchen 2, 3 und 4.The invention relates to a cartridge with this fit end converters according to the preamble of claim 1 and sub-claims 2, 3 and 4.

Elektrodynamische Tonabnehmer dienen in erster Linie zur Erhöhung der akustischen Endlautstärke von Saiteninstrumenten mit zu kleinem Resonanzkörper.Electrodynamic pickups are primarily used to increase the final acoustic volume of Stringed instruments with too small a resonance body.

In der bisherigen Praxis werden dazu Tonabnehmer mit einer oder mehreren Spulen benutzt, die allerdings anordnungsbedingt, fast ausschließlich nur den Schwingungsanteil senkrecht zur z. B. Gitarrenoberfläche aufzunehmen in der Lage sind.In previous practice, pickups were used for this used with one or more coils, however due to the arrangement, almost exclusively that Vibration component perpendicular to the z. B. guitar surface are able to record.

Ein Patent für eine Lösung dieser Art, ist z. B. in der Klasse B 06 B Übertragen von Schwingungen, Unterklasse H 03 B, und folgend G 10 H- Elektrophonische Musikinstrumente unter 318 in der Offenlegungsschrift: DE 30 38 994 A1 aufgeführt.A patent for a solution of this type is e.g. B. in class B 06 B transmission of vibrations, Subclass H 03 B, and subsequently G 10 H- Electrophonic musical instruments under 318 in the Publication: DE 30 38 994 A1 listed.

Andere, ähnliche Lösungen sind einzusehen im Guitar-Player Ausgabe 7/85 z. B. Seite 2, oder im "Fachblatt" Ausgabe 8/85 z. B. Seite 50, oder im Heft 7/8 85 von musik spezial z. B. die Seiten 40, 41.Other, similar solutions can be seen in the Guitar Player issue 7/85 z. B. Page 2, or in the "Fachblatt" issue 8/85 z. B. page 50, or in issue 7/8 85 by musik spezial z. B. Pages 40, 41.

Besonders bei "vollelektrischen" Gitarren fällt es oft auf, daß ihr Klang nichts zu wünschen übrig läßt, solange sie nicht verstärkt werden.It is particularly the case with "fully electric" guitars often that their sound leaves nothing to be desired, as long as they are not reinforced.

Beim Verstärken der Gitarre über einen herkömmlichen Tonabnehmer entsteht dann oft ein relativ langweiliger und undifferenzierter Ton, weil nur 50% des Signals vom Tonabnehmer erfasst werden. When amplifying the guitar over a conventional one Pickups then often result in a relatively boring and undifferentiated sound because only 50% of the signal be picked up by the pickup.  

Der Erfindung liegt die Aufgabe zugrunde, den bei herkömmlicher elektrodynamischer Ansteuerung der Verstärkerstufen für - insbesondere direkt oder indirekt handgezupfte - Saiteninstrumente auftretenden Verlust des tonalen Charakters, der in der Praxis durch zum Teil sehr aufwendige, kostspielige Systeme zur Verzerrung, synthetischen Klanganreicherung oder Kompression kompensiert wird, in einfacher Weise zu umgehen.The invention is based on the object conventional electrodynamic control of the Amplifier stages for - especially directly or indirectly hand-plucked - stringed loss occurring of the tonal character that in practice sometimes very complex, expensive systems for Distortion, synthetic sound enhancement or Compression is compensated for in a simple way bypass.

Da die Saitenschwingung von Gitarren eine annähernde Kreisform darstellt, die sich durch den manuellen Anschlag individuell und permanent verändert, und besonders der eigentliche Anschlag starke Asymmetrien erzeugt, muß die Schwingung in ihrer Gesamtheit z. B. in der durch Anspruch 1 aufgezeigten Weise zumindest erfasst, - und besser auch dementsprechend verarbeitet und wiedergegeben werden - um eine sinnvolle Verstärkung zu ermöglichen.Because the string vibration of guitars is approximate Represents circular shape, which is characterized by the manual Stop changed individually and permanently, and especially the actual stop, strong asymmetries generated, the vibration in its entirety z. B. at least in the manner indicated by claim 1 recorded - and better processed accordingly and reproduced - by a meaningful reinforcement to enable.

In der praktischen Realisisation wird die angestrebte phasentreue Wiedergabe dadurch erreicht, daß die zwei, vom Tonabnehmer kommenden, nach Schwingungsebenen getrennten Summensignale, - bei einer Baßgitarre z. B. 2 × 4 Einzelsignale von den je 4 zueinander parallel angebrachten Tonabnehmern - durch zwei separate Verstärkerzweige laufen, und dann mit der aus Anspruch 1 und 3 vorgegebenen Anordnung zweier weitgehend identischer Lautstärkerchassi, wieder in akustische Energie gewandelt werden.In practical implementation, the desired True-to-phase playback achieved in that the two, coming from the pickup, according to vibration levels separate sum signals, - with a bass guitar z. B. 2 × 4 individual signals of 4 each parallel to each other attached pickups - by two separate amplifier branches run, and then with that of claim 1 and 3 predetermined arrangement of two largely identical volume chassis, again in acoustic Energy to be changed.

Da die systematische Anordnung der ersten und letzten Wandler dabei prinzipiell dieselbe ist, findet die akustische Integration des verstärkten Klanges, entsprechend seiner ursprünglichen Entstehung, wieder in der Luft statt. Asymmetrien, Intermodulation und Interferenzen die das Original ausmachen, bleiben weitgehend erhalten. Because the systematic arrangement of the first and last The converter is basically the same, she says acoustic integration of the amplified sound, according to its original creation, again held in the air. Asymmetries, intermodulation and Interferences that make up the original remain largely preserved.  

Die Wandlersysteme nach Anspruch 1 ermöglichen es, Gitarren derart zu verstärken, daß sie keiner klanglichen "Aufwertung" durch mehr oder weniger verfälschende Maßnahmen, - die letzten Endes doch kaum zufriedenstellen - mehr bedürfen.The converter systems according to claim 1 enable To amplify guitars in such a way that they have no sound "Appreciation" by more or less adulterating Measures, - in the end hardly satisfying - need more.

Wird zur Verstärkung einer Baßgitarre z. B. nur der Tonabnehmer aus Anspruch 1 eingesetzt, so ergibt sich bei einer Summierung aller 8 Signale in einen Verstärkerkanal, zwischen den je 4 zueinander versetzten Einzeltonabnehmern eine Phasenverschiebung von 90° und die Grundwellenform bleibt bei vergrößerter Amplitude erhalten.Is used to reinforce a bass guitar z.
