Description
Die Erfindung bezieht sich auf einen Tonabnehmer für Musikinstrumente mit mindestens einer schwingfähigen Resonanzkörperwand, insbesondere für Saiten- und Schlaginstrumente, gemäß Oberbegriff des Anspruchs 1.The invention relates to a Pickups for Musical instruments with at least one vibrating resonance body wall, especially for String and percussion instruments, according to the preamble of the claim 1.
An solche Tonabnehmer werden eine Reihe von Anforderungen gestellt: Möglichst naturgetreue Wiedergabe des aufgenommenen Klangspektrums; kleine Baugröße und gute Montierbarkeit, damit er möglichst unauffällig am Saiten- oder Schlaginstrument montiert werden kann; gute Herstellbarkeit; Störunanfälligkeit und gute Abschirmung, d.h. kein negativer Einfluß von Störfeldern, um nur die wichtigsten zu nennen.Such pickups will be one There are a number of requirements: reproduction that is as lifelike as possible of the recorded sound spectrum; small size and easy to assemble, so that he is as possible inconspicuous can be mounted on the string or percussion instrument; good manufacturability; noise immunity and good shielding, i.e. no negative influence from interference fields to only the most important to call.
Der Erfindung liegt die Aufgabe zugrunde, einen Tonabnehmer der eingangs genannten Art zu schaffen, mit welchem die vorstehend aufgeführten Anforderungen auf besonders günstige Weise erfüllt werden und mit dem es darüber hinaus ermöglicht ist, das Frequenzspektrum, welches von piezoelektrischen Stegtonabnehmern geliefert wird, so zu ergänzen, daß auch bei großen Lautstärken (Musikwiedergabe in Sälen) ein überraschend naturgetreuer Sound erreicht werden kann.The invention is based on the object to create a pickup of the type mentioned, with which the requirements listed above on particularly cheap Way to be fulfilled and with it over it allows beyond is the frequency spectrum of piezoelectric bridge pickups is delivered to complete so that too for large volumes (Music playback in halls) a surprising lifelike sound can be achieved.
Erfindungsgemäß wird die gestellte Aufgabe durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst, nämlich dadurch, daß der Tonabnehmer mindestens einen Piezo-Sensor aufweist und an der Resonanzkörperwand – vorzugsweise an deren Innenseite von außen nicht sichtbar – in schwingungübertragendem Kontakt befestigt ist und daß die Piezo-Signale des Piezo-Sensors durch mindestens eine an diesen angeschlossenen aktive Transistor-Beschaltung verstärkbar sind.According to the invention, the object is achieved by solved the features specified in the characterizing part of claim 1, namely by that the pickup has at least one piezo sensor and - preferably on the resonance wall on the inside from the outside not visible - in schwingungübertragendem Contact is fixed and that the Piezo signals from the Piezo sensors can be amplified by at least one active transistor circuit connected to them.
Vorteilhafte Weiterbildungen sind in den Ansprüchen 2 bis 16 angegeben. Gemäß der Verwendung nach Anpruch 17 werden vorteilhafterweise für den Piezo-Sensor piezokeramische Sensoren, Piezo-Film-Sensoren, Piezo-Polymer-Sensoren oder Backelektret-Sensoren verwendet.Advantageous further developments are in the claims 2 to 16 specified. According to the use According to claim 17, piezoceramic are advantageously used for the piezo sensor Sensors, piezo film sensors, piezo polymer sensors or back electret sensors are used.
Der Tonabnehmer nach der Erfindung findet eine bevorzugte Anwendung bei akustischen Gitarren und wird dabei an der Decke der Gitarre schwingungsübertragend angekoppelt, bevorzugt unsichtbar an der Innenseite der Decke. Es ist gefunden worden, daß das so gewonnene Körperschallspektrum einen besonders „warmen" Klang ergibt, der sich überraschend gut mit dem Frequenzspektrum eines piezoelektrischen Stegtonabnemers an der selben Gitarre mischen läßt, was sich besonders bei großen Lautstärken (natürlicher Klang ohne Übersteuerung) bemerkbar macht. Dementsprechend ist gemäß einer bevorzugten Ausführung vorgesehen, daß die Piezo-Signale des „Decken"-Tonabnehmers (erste Piezo-Signale) mit denjenigen (zweite Piezo-Signale) eines sogenannten Stegtonabnehmers gemischt werden, d.h. eines Piezo-Tonabnehmers, der in den Gitarrensteg integiert ist und dessen Signale aufgrund der von den Saiten über Druckstücke auf ihn ausgeübten Kräfte gebildet werden, wobei vorzugsweise die ersten und zweiten Piezo-Signale durch je einen Vorverstärker vorverstärkbar und in einem nachgeschalteten Gitarrenverstärker oder einer Mischeinrichtung mit wählbarer Gewichtung der beiden Klangkomponenten mischbar sind.The cartridge according to the invention finds a preferred application in acoustic guitars and will coupled to the ceiling of the guitar to transmit vibrations, preferred invisible on the inside of the ceiling. It has been found that this structure-borne noise spectrum obtained in this way gives a particularly "warm" sound that themselves surprising well with the frequency spectrum of a piezoelectric bridge tone absorber lets mix on the same guitar what especially at high volumes (more natural Sound without overdrive) noticeable makes. Accordingly, according to one preferred execution provided that the Piezo signals from the "blanket" pickup (first Piezo signals) with those (second piezo signals) of a so-called Bridge pickup are mixed, i.e. a piezo pickup, which is integrated in the guitar bridge and whose signals due to the from the strings over plungers exercised on him personnel are formed, preferably the first and second piezo signals with one preamp each vorverstärkbar and in a downstream guitar amplifier or mixer with selectable Weighting of the two sound components are miscible.
Es gibt Spielweisen der Gitarre, bei denen zur Rhythmus-Betonung die Decke mit Handballen oder Fingern angeschlagen wird. Auch zur naturgetreuen Übertragung solcher Percussion-Effekte ist der Tonabnehmer nach der Erfindung besonders geeignet. Ein Nebeneffekt ist, daß man elektronische Rhythmus-Synthesizer durch ein vom Deckentonabnehmer geliefertes und entsprechend verstärktes Schlagsignal der Decke auch über größere Entfernung taktsynchron einschalten kann.There are ways of playing the guitar where the rhythm is emphasized, the ceiling with the ball of the hand or fingers is struck. Also for the lifelike transmission of such percussion effects the pickup according to the invention is particularly suitable. A side effect is that one electronic rhythm synthesizer by a from the ceiling pickup supplied and appropriately amplified impact signal of the ceiling also about greater distance can switch on isochronously.
Weitere Merkmale und Vorteile sowie Aufbau und Funktion des Gegenstandes der Erfindung werden im folgenden anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. In der Zeichnung zeigt in z.T. schematischer, vereinfachter Darstellung:Other features and advantages as well Structure and function of the subject matter of the invention are as follows explained in more detail with reference to exemplary embodiments shown in the drawing.

Dieser Vorteil läßt sich auch verwirklichen, wenn der Tonabnehmer an die Decke eines Streichinstrumentes, z. B. in der Gestalt von Violine, Viola, Cello oder Kontrabass, schwingungsübertragend angekoppelt ist und diese Instrumente zusätzlich eien Stegtonabnehmer aufweisen, wobei indessen schon der Deckentonabnehmer für sich einen überraschend natürlichen Klang ergibt.This advantage can also be realized if the pickup on the ceiling of a string instrument, e.g. B. in in the form of violin, viola, cello or double bass, transmitting vibrations is coupled and these instruments also have a bridge pickup have, but the ceiling pickup is surprising for itself natural Sound results.
Dementsprechend kann der Tonabnehmer auch mit der Resonanzkörperwand eines Klaviers bzw. eine Flügels schwingungsübertragend verbunden sein oder an die Decke eines anderen Saiteninstrumentes, z. B. in Gestalt von Banjo, Balalaika oder Mandoline, schwingungsübertragend angekoppelt sein.Accordingly, the pickup can also with the sound box wall of a piano or grand piano vibration transmitting connected or to the ceiling of another stringed instrument, z. B. in the form of banjo, balalaika or mandolin, vibration transmitting be coupled.
