Description
Vorrichtung zur Hervorbringung eines Tremolos an elektrischen Musikinstrumenten Bekanntlich trägt ein Tremolieren des Tones viel zur Belebung der Musik bei. Das Tremolo kann durch eine geringe Frequen,zänderung erreicht werden, und zwar kann diese, wie die Erfahrung zeigt, innerhalb des Intervalls eines Halbtones bleiben.Device for producing a tremolo on electrical musical instruments As is well known, tremolating the tone contributes a lot to the liveliness of the music. That Tremolo can be achieved by a small change in frequency, namely can experience shows that these remain within the interval of a semitone.
Bei elektrischen Musikinstrumenten, bei denen durch eine Tastatur eijaes der beiden Abstimmelemente des elektrischen Schwingungskreises (Kapazität oder lnduktivität) verändert wird, muß zu diesem Zweck eine besondere Vorrichtung angebracht werden. Von dieser ist zu verlangen, daß sie unabhängig von der Höhe des Tones diesen immer um das gleiche Intervall zu variieren gestattet. Aus diesem Grund wird das sonst unveränderliche Abstimmelement derart ausgeführt, daß. sein Wert bis zu etwa den i, i2fachen und somit jeder Ton um das Intervall eines Halbtones stetig verändert werden kann.In the case of electric musical instruments, in which by a keyboard eijaes of the two tuning elements of the electrical oscillation circuit (capacitance or inductance) is changed, a special device must be used for this purpose be attached. This is to be demanded that it is independent of the amount of the tone this is always allowed to vary by the same interval. For this Reason, the otherwise unchangeable tuning element is carried out in such a way that. be Value up to about i, i2 times and thus every tone around the interval of a semitone can be changed continuously.
Normalerweise wird durch die Tastatur die Kapazität des Schwingungskreises verändert, so daß in diesem Fall die Induktivität um das i,i2fache ihres Wertes veränderlich gemacht werden muß. Wie dies in einfacher @#Veise geschehen kann, zeigt die Abbildung Die Ihduktivität, im vorliegenden Fall bestehend..us der Spule 2 mit dem Eisenkern 3, wird durch Niederdrücken des elastischen Eisenbleches i verändert. Die Größe des letzteren ist so bemessen, daß gerade die gewünschte Frequenzänderung erreicht wird. Die Bedienung dieses Vibrators kann von Fuß oder Hand erfolgen und läßt dem Spieler sowohl in bezug auf Schnelligkeit als auch, auf Größe der Frequ@enzänderung volle Froilieit.Normally the capacity of the oscillatory circuit is determined by the keyboard changed, so that in this case the inductance is i, i2 times its value must be made mutable. How this can be done in a simple @ # way shows the figure The inductance, in the present case consisting of the coil 2 with the iron core 3 is changed by depressing the elastic iron sheet i. The size of the latter is such that just the desired change in frequency is achieved. The operation of this vibrator can be done by foot or hand and leaves the player both in terms of speed and the size of the frequency change full happiness.
