Description

Lautstärkeregelanordnung an elektrischen Musikinstrumenten Bei der Verwendung der bekannten druck.-abhängigen Widerstände zur Lautstärkeregelung bei. ,elektrischen Musikinstrum-enten,. beispielsweise in der Weise, daß der Widerstand unter den Tasten ;oder bei drahtförmig ausgebildeten Spielvorrichtungen unter der Spielschiene angeordnet ist, hat sich herausgestellt, daß beim Einschalten des Widerstandes stets störende Knackgeräusche hörbar wurden. Versuche haben vergeben, daß die Ursache dieser Störung kapazitive Aufladungen im Regelwiderstand, wahrscheinlich zwischen. den beiden Elektroden, sind.Volume control arrangement on electrical musical instruments Use of the well-known pressure-dependent resistors for volume control. , electric musical instruments ,. for example in such a way that the resistance under the buttons; or under the wire-shaped gaming devices Play rail is arranged, it has been found that when you turn on the resistor annoying crackling noises were always audible. Attempts have forgiven that cause this disturbance capacitive charges in the rheostat, probably between. the two electrodes, are.

Gemäß der Erfindung wird diese Erscheinung dadurch beseitigt, da;ß parallel zu -dem druckabhängigen Lautstärkeregelwiderstandein Ohmscher Widerstand, vorzugsweise -einHoch-,ohmwiderstand, .zur Ableitung der störenden statischen. Entladungen vorgesehen ist, der so bemessen ist, d.aß her wesentlich kleiner, insbesondere kleiner als 1/1o des kapazitiven Widerstandes des druckabhängigen Widerstandes bei den höchsten Frequenzen ist bzw. des Ableitewiderstandes des Kopplungskondensators, da dieser das =Spannungst@eilverhältnis maßgebend beeinflußt.According to the invention, this phenomenon is eliminated in that; ß parallel to the pressure-dependent volume control resistor an ohmic resistor, preferably -a high-, ohmic resistance, .to derive the disturbing static. Discharges is provided, which is dimensioned, d.aß her much smaller, in particular smaller than 1 / 1o of the capacitive resistance of the pressure-dependent resistance at the highest Frequencies is or the leakage resistance of the coupling capacitor, as this the = stress ratio has a decisive influence.

Es ist an sich bekannt, bei druckabhängigen Widerständen ParalleIwiderstände Bei den bekannten Einrichtungen dient die übrigens wahlweise ParaUelschal--tung des Ohinschen Widerstandes zum druckabhängigem Widerstand dazu, den. Regelbereich dieses Widerstandes zu erweitern.It is known per se to have parallel resistances in the case of pressure-dependent resistances Incidentally, the optional parallel circuit is used with the known devices of the Ohin resistance to the pressure-dependent resistance to the. Control range to expand this resistance.

Die Abbildung veranschaulicht ein Ausführungsbeispiel - des Erfndungsgegenstandes. Die von der Verstärkerröhre r kommenden Impulse gehen über den Kopplungskondensator 5, über den druckabhängigen Regelwiderstand 2 und den beispielsweise vorgesehenen Pedalregler 3 zum Verbraucher. Parallel zu dem Regelwiderstand 2 ist ein Hoch-,olunwiderstand q. geschaltet, der die statischen Entladungen so weit ableitet, daß keinerlei Störungen im. Wiedergabegerät sich bemerkbar machen.The figure illustrates an exemplary embodiment - of the subject matter of the invention. The impulses coming from the amplifier tube r go through the coupling capacitor 5, via the pressure-dependent control resistor 2 and the example provided Pedal controller 3 to the consumer. A high and low resistance is parallel to the variable resistor 2 q. switched, which dissipates the static discharges so far that no interference whatsoever in the. Playback device make themselves noticeable.
