Description
Anlage zur Aussendung von Schallsignalen in beliebigen 1Kedien (Wasser, Luft). Die Erfindung hat Anlagen zur. Schallerzeugung unter Wasser mittels elektromagnetischer oder elektrodynamischer Sender zum Gegenstand. Der Zweck der Erfindung und das Charakteristikum dieser Anlagen ist, daß die bisher hierfür verwendete rotierende Maschine vermieden wird, und daß durch den Sender ein schlagähnlicher Ton erzeugt werden kann, der in gewissen Fällen Vorteile hat. Eine besondere Bedeutung gewinnen Anlagen dieser Art auf Schiffen, wo beim Versagen des Netzes die Anlage betriebsfähig bleiben soll, und ferner dort, wo die Aufgabe besteht, Schallsender an Stellen des Meeres zu verlegen, die beispielsweise wesentliche Teile des Jahres hindurch unzugänglich sind, und wo einerseits im Wasser Schlagmechanismen nicht liegen sollen und anderseits eine Wartung und Pflege einer rotiefenden Maschine an Land ausgeschlossen ist.System for the transmission of sound signals in any media (water, Air). The invention has facilities for. Generating sound underwater by means of electromagnetic or electrodynamic transmitter to the object. The purpose of the invention and the characteristic of these systems is that the rotating machine previously used for this purpose is avoided and that the transmitter can generate a beat-like sound that has advantages in certain cases. Systems of these are of particular importance Type on ships where the system should remain operational in the event of a network failure, and also where the task is to relocate sound transmitters to places in the sea, for example, which are inaccessible for significant parts of the year, and where on the one hand impact mechanisms should not lie in the water and on the other hand one Maintenance and care of a rotating machine on land is excluded.
Das gemeinsame Kennzeichen aller von der Erfindung umfaßten Schallerzeugungsanlagen besteht darin, daß ein stromerzeugender Erregervibrator außerhalb des Wassers (an der Station an Land oder an Bord) und ein elektrisch betriebener Schallsender an der eigentlichen Sendestelle, z. B. unter Wasser, angeordnet ist, von denen der Erregervibrator an Stelle der rotierenden Maschine zur Erregung des Schallsenders verwendet wird. Es ist ein besonderer Vorteil der Erfindung, däß der Schallsender seinen Strom in: ;der gedämpften Kurvenform erhalten kann, die der Schwingungskurve des Erregervibrators entspricht. Ist in diesem Falle der Erregervibrator erheblich geringer gedämpft als der Schallsender, so wird, da die beiden zusammen ein aus einem schwächer und einem stärker gedämpften Schwingungsgebilde zusammengesetztes gekoppeltes System bilden, die Dämpfung des Schallsenders herabgesetzt, ohne .den Klangcharakter des Schlages des Erregervibrators zu verlieren.The common characteristic of all sound generation systems covered by the invention consists in the fact that a current-generating exciter vibrator outside the water (an the station on land or on board) and an electrically operated sound transmitter the actual broadcasting station, e.g. B. under water, of which the Exciter vibrator instead of the rotating machine to excite the sound transmitter is used. It is a particular advantage of the invention that the sound transmitter its current in:; the damped waveform, that of the oscillation curve of the exciter vibrator. In this case, the exciter vibrator is significant less attenuated than the sound transmitter, so because the two together one off composed of a weaker and a more strongly damped oscillation structure form coupled system, the attenuation of the sound transmitter is reduced, without To lose the sound character of the beat of the exciter vibrator.
Man kann vorteilhaft zwei ganz ähnlich gebaute Vibratoren verwenden, von denen der eine als Erregervibrator; der andere als Schall- Sender wirkt. Die Energie wird letzterem c om Erregervibrator durch Kabel zugeführt.It is advantageous to use two vibrators of very similar construction, one of them as an exciter vibrator; the other as sonic Channel works. The energy is supplied to the latter via cables.
Das Beispiel der Abbildung zeigt eine Ausführungsform der Erfindung mit- -Schlagantrieb des Erregervibrators.The example of the figure shows an embodiment of the invention with-impact drive of the exciter vibrator.
Bei deni; Beispiel der Abbildung dient als Erregervibrator. ein elektromagnetischer Vibrator i bekannter Ausführungsform, der dem Unterwassersender 2 gleicht. Auf seine Membran wirkt ein pneumatisches Schlagwerk 3. Die Schwingungen der Membrane erzeugen in der Wicklung q. des Erregervibrators einen gedämpften Wechselstrom, der seinerseits die Wicklung 5 des Unterwassersenders passiert und dessen Membrane entsprechend der Bewegung der Membrane des Vibrators i in Schwingungen versetzt.At deni; The example in the figure serves as an exciter vibrator. an electromagnetic one Vibrator i of a known embodiment, which is similar to the underwater transmitter 2. On his A pneumatic hammer mechanism acts on the diaphragm. 3. The vibrations of the diaphragm generate in the winding q. of the exciter vibrator a damped alternating current, which in turn the winding 5 of the underwater transmitter happens and its membrane accordingly the movement of the diaphragm of the vibrator i vibrated.
Als Antriebsmittel kann für derartige Anlagen zweckmäßig Preßgas dienen, das in Flaschenbatterien oder absorbiert in Flüssigkeiten in so beträchtlichen Mengen in der Station aufgespeichert werden - kann, daß es einen monatelangen Betrieb der Anlage ohne Neufüllung ermöglicht. Natürlich kann der Schlag auch auf elektrische oder irgendeine andere Weise erzeugt werden. Automatische Schlagwerke mit beliebigen Schlagzahlen stehen in der einschlägigen Technik zur Verfügung.Compressed gas can expediently serve as the drive means for such systems, that in bottle batteries or absorbed in liquids in such considerable quantities can be stored in the station - that it can run for months Facility made possible without refilling. Of course, the blow can also be electric or any other way. Automatic striking mechanisms with any Stroke numbers are available in the relevant technology.
Einrichtungen der geschilderten Art weisen schließlich noch den Vorteil auf, daß der Erregervibrator gleichzeitig als Luftschallsender wirken kann. Die Schläge eines großen Vibrators der in der Abbildung mit i gezeichneten Art sind auch in Luft weit zu hören.Finally, facilities of the type described have the advantage on that the exciter vibrator can also act as an airborne sound transmitter. the Blows of a large vibrator of the type shown in the figure with i can also be heard far in the air.
An Stelle eines Unterwasserschallsenders kann auch ein Luftsender oder eine Mehrzahl von Sendern in beliebigenMedien durch einen solchen Erregervibrator gespeist werden.An air transmitter can also be used instead of an underwater sound transmitter or a plurality of transmitters in arbitrary media by such an exciter vibrator be fed.
