Description
Einrichtung zur Übertragung von Musik und Sprache mit hochfrequenten elektrischen Schwingungen. In dem Hauptpatent ist ein Verfahren zur Übertragung von Musik und Sprache mit hochfrequenten elektrischen Schwingungen beschrieben, bei dem mehrere Schallaufnehmer, Mikrophone o. dgl. räumlich getrennt voneinander angeordnet sind, deren Einwirkungen auf die gemeinsame Sendevorrichtung während des Sendens in so kurzen Zeitabständen abwechselnd unterbrochen und wiederhergestellt werden, daß 'die nacheinander von den verschiedenen Orten der Aufnahme auf die Sendeantenne geleiteten Energien bei der Wiedergabe mittels Empfang durch einen der bekannten Rundfunk-Empfangsapparate die bekannte, durch Phasenverschiebung bewirkte Klangverbesserung hervorrufen.Device for the transmission of music and speech at high frequencies electrical vibrations. In the main patent is a method of assignment described by music and speech with high-frequency electrical oscillations, in which several sound pickups, microphones or the like are spatially separated from one another are arranged, the effects of which on the common transmitting device during of sending is alternately interrupted and restored at such short time intervals be that 'the one after the other from the different places of reception on the transmitting antenna conducted energies during playback by means of reception by one of the known Radio receivers the well-known sound improvement brought about by phase shift cause.
Es hat sich nun gezeigt, daß eine Plastik der Wiedergabe auch dadurch erreicht werden kann, daß ganze Gruppen von zusammengeschalteten Aufnahmevorrichtungen sich einander abwechseln. Die erzielte Sendeenergie kann sich also auch aus einer Folge von zwei oder mehreren einander abwechselnden Durchschnittsauswirkungen der Mikrophongruppen oder aber auch aus einem Wechsel von derartigen Durchschnittsauswirkungen mit den Auswirkungen von Einzelaufnahmevorrichtungen zusammensetzen.It has now been shown that a sculpture can also be reproduced by this can be achieved that whole groups of interconnected recording devices take turns. The transmission energy achieved can also be derived from a Sequence of two or more alternating average effects of the Microphone groups or from a change of such average effects compound with the effects of single capture devices.
Es werden also zunächst zwei oder mehrere verteilt angeordnete Aufnahmevorrichtungen zu einer Gruppe zusammengeschaltet, welche, da alle Vorrichtungen gleichzeitig einwirken, eine Durchschnittseinwirkung ergeben. Dies ist an sich bekannt. Neu ist vielmehr, zwei oder mehr derartiger Gruppen gemäß dem Hauptpatent einander abwechselnd zur Einwirkung auf die Sendeantenne zu bringen. Die Anwendung derartiger Gruppen gestattet vor allem die Lautstärke der einzelnen Aufnahmemikrophone gut gegeneinander auszugleichen, da man sie örtlich nach Belieben anordnen kann.So there are initially two or more receiving devices arranged in a distributed manner interconnected to a group which, since all devices act simultaneously, result in an average action. This is known per se. Rather, what is new is two or more such groups according to the main patent alternate with each other Bringing action on the transmitting antenna. The use of such groups is permitted Above all, balance the volume of the individual recording microphones well against each other, because you can arrange them as you wish.
Es bleibt natürlich auch vorbehalten, einzelne Mikrophone bzw. Aufnahmevorrichtungen mit ganzen Gruppen abwechseln zu lassen.It is of course also reserved to individual microphones or recording devices alternate with whole groups.
Eine Ausführungsform des Erfindungsgedankens zeigt die Abbildung. Zwei Mikrophongruppen, bestehend aus den Mikrophonen 1l,11", 1M6 und MIIQ, MM, kommen infolge der Zwischenschaltung des Kollektors K abwechselnd zur Einwirkung auf den Anschluß A des Sendeapparates. Die beiden Wechsel werden vorteilhafterweise durch den induktiven Widerstand I überbrückt, der Kollektor K nicht in den direkten Mikrophonstrom, vielmehr in den Sekundärkreis verlegt, um Störgeräusche abschwächen oder ganz verhindern zu können. B bedeutet die Batterien, Tr die Transformatoren.An embodiment of the inventive concept is shown in the figure. Two microphone groups, consisting of microphones 1l, 11 ", 1M6 and MIIQ, MM, come as a result of the interposition of the collector K alternately to act on the Connection A of the transmitter. The two changes are advantageously carried out the inductive resistance I bridged, the collector K not in the direct microphone current, rather, it is moved to the secondary circuit in order to attenuate or completely prevent interfering noises to be able to. B means the batteries, Tr the transformers.
