Description

Unterwasserschallempfänger. Gegenstand der Erfindung ist eine Empfangseinrichtung für Unterwasserschallsignale, bei der durch die empfangende Membran sowohl ein Mikrophon wie ein elektromagnetischer Stromerzeuger mit Induktionsspule und relativ zu ihr beweglichem Anker erregt wird. Das Mikrophon, das weit empfindlicher ist als der elektromagnetische Stromerzeuger, dient dazu, um das Auftreten von Signalen überhaupt erst festzustellen. Da es aber zufälligen Störungen aussetzt ist, infolge deren auch seine Lautstärke wechselt, wird der elektromagnetische Stromerzeuger verwendet, wenn es auf genaue Bestimmung der Lautstärke ankommt, beispielsweise um in bekannter Weise die Richtung- zu bestimmen, aus der die Schallwellen herrühren.Underwater sound receiver. The invention relates to a receiving device for underwater sound signals with both a microphone through the receiving membrane like an electromagnetic power generator with an induction coil and relative to it movable armature is excited. The microphone, which is far more sensitive than that electromagnetic power generator, serves to prevent the occurrence of signals at all to be determined first. But since it is exposed to random disturbances, as a result of them its volume also changes, the electromagnetic power generator is used, when it comes to the exact determination of the volume, for example in order to be familiar Way to determine the direction from which the sound waves originate.

Die gleichzeitige Anbringung des elektromagnetischen Stromerzeugers und des Mikrophons am Empfangsapparat macht keinerlei Schwierigkeiten, wie die Zeichnung zeigt. Die auf der Membran b angebrachte Masse m wird von den durch das Wasser ankommenden Schallwellen in Schwingungen versetzt. An diesen Schwingungen nimmt auch die Zunge -- teil, die an ihrem Ende auf der einen Seite das Mikrophon k, auf der anderen Seite den Anker r trägt, durch dessen Bewegungen in der Spule t elektrische Ströme erzeugt werden. Das Mikrophon k und die Spule t können vermittels des Umschalters ii abwechselnd mit dein Abhörer a verbunden werden. Beim praktischen Gebrauch wird man zwischen den Telephonhörer und jeden der beiden Stromerzeuger noch Verstärker einschalten.The simultaneous attachment of the electromagnetic power generator and the microphone to the receiver does not cause any difficulties, as the drawing shows. The mass m attached to the membrane b is caused to vibrate by the sound waves arriving through the water. The tongue - also takes part in these vibrations. At its end it carries the microphone k on one side and the armature r on the other, the movements of which generate electrical currents in the coil t. The microphone k and the coil t can be alternately connected to your listener a by means of the switch ii. In practical use, amplifiers will be connected between the telephone receiver and each of the two power generators.
