P.A. 060 434*26. 1.6,P.A. 060 434 * 26. 1.6, Magnetsystem mit SpezialdämpfungMagnet system with special damping BESCHE-EIBUHGBeschE-EIBUHG Die Neuerung bezieht sieh auf ein Magnetsystem, in welchem die Dämpfungslöoher an der hinteren Polplatte so angebracht sind, daß sie durch eine Mchtguelle, die von hinten durchstrahlt,, beobachtet werden können.The innovation relates to a magnet system in which the damping holes are attached to the rear pole plate so that they are through a Power sources which can be seen through from behind. Nach dem Stand der Technik wird die Dämpfung und Abstimmung der Mikrofonsysteme durch .tobringen verschiedener Löcher an verschiedenen Punkten des Magnetsystems durch Versuche erreicht.According to the state of the art, the attenuation and tuning of the microphone systems is done by bringing different holes at different points of the magnet system achieved through experiments. Der Nachteil war, daß die Lage der Schwingspule zur Lage des Magnetfeldes nicht kontrolliert werden.konnte»The disadvantage was that the location of the voice coil related to the location of the magnetic field could not be controlled. Die Heuerung dient dem Zweck, diesen Mangel zu beheben.The purpose of the hiring is to remedy this deficiency. Die Dämpfungslöeher sind an der Hinteren Polplatte des Systems so angebracht, daß sie mittels einer von hinten durchstrahlenden lichtquelle beobachtet und dadurch genau eingestellt und besser kontrolliert werden können. Die kleinste Verschiebung wird auf Grund der-Lichtmenge sichtbar* Durch die erreichte präzise Zentrierung der Schwingspule in der Mitte des Magnetfeldes wird ein einwandfreier und gleichmäßiger Frequenzgang erzielt.The attenuation holes are attached to the rear pole plate of the system in such a way that that they are observed by means of a light source shining through from behind and can therefore be precisely adjusted and better controlled. the The smallest shift is visible due to the amount of light * Through the achieved precise centering of the voice coil in the middle of the magnetic field a flawless and even frequency response is achieved. Die Heuerung wird dargestellt durch Zeichnung Z 1o2. Abbildung 1 zeigt eine Ansieht von oben, Abbildung 2 eine seitliehe Ansieht im Schnitt. Eine Membrane a trägt eine Schwingspule b, diese ragt in Aussparung c. Die Polplatte d hat verschiedene Dämpfungslöcher ©,durch welche die Schwingspule b beobachtet werden kann.The hiring is represented by drawing Z 1o2. Figure 1 shows a view from above, Figure 2 a side view in section. A membrane a carries a voice coil b, this protrudes into recess c. The pole plate d has different damping holes © through which the Voice coil b can be observed.
