Description

Vorliegende Erfindung betrifft einen Übertrager-Zusatz zur Ausnutzung eines beliebigen Radio-Empfängers zur Verstärkung und Wiedergabe niederfrequenter Schwingungen unter Verwendung eines Mikrofons, einer Stromquelle, eines Übertragers mit verschiedenen Übersetzungsverhältnissen (Anzapfungen) und eines Radio-Empfängers nebst Lautsprecher. Mikrofon und Batterie werden hintereinander an die Primär-Seite des Übertragers geschaltet. Auf der Sekundär-Seite des Übertragers ermöglichen mehrere Anzapfungen (a, b, c, d...) die genaue Anpassung des Übertragers an die jeweilige Schaltung des NF-Teiles des Empfängers. Eine Schaltung gemäss vorliegender Erfindung ist in der Abbildung dargestellt.The present invention relates to a transmitter add-on for using any radio receiver to amplify and reproduce low-frequency vibrations using a microphone, a power source, a transmitter with different transmission ratios (taps) and a radio receiver and loudspeaker. The microphone and battery are connected in series to the primary side of the transformer. On the secondary side of the transformer, several taps (a, b, c, d ...) allow the transformer to be precisely matched to the respective circuit of the LF part of the receiver. A circuit according to the present invention is shown in the figure.

In der beliegenden Zeichnung bedeuten:In the accompanying drawing:

M = MikrofonM = microphone

B = Batterie (Stromquelle)B = battery (power source)

T = Tonabnehmeranschluß des RundfunkgerätesT = pickup connector of the radio

Ü = Übertrager mit den Anzapfungen a, b, c, d,..Ü = transformer with taps a, b, c, d, ..

die den elektrischen Verhältnisses der ganzen Anlage entspr. gewählt werden müßen, um ein Maximum an Lautstärke und Klangreinheit zu erzielen.which have to be selected according to the electrical conditions of the entire system in order to achieve maximum volume and sound purity.

Claims (1)

Anspruch 1: Übertrager-Zusatz für die zur Ausnutzung eines beliebigen Radio-Empfängers Verstärkung und Wiedergabe niederfrequenter Schwingungen, die von einem Mikrofon herrühren, dadurch gekennzeichnet, daß der Übertrager zwischen Mikrofonanordnung und Tonabnehmeranschluß mit verschiedenen Anzapfungen im Sekundär-Kreis versehen ist, welche die jeweils günstigste Anpassung der Mikrofonanordnung an die gegebene NF-Schaltung des betr.Empfängers ermöglichen.Claim 1: Transmitter add-on for the use of any radio receiver amplification and reproduction of low-frequency vibrations originating from a microphone, characterized in that the transmitter between the microphone arrangement and the pickup connection is provided with different taps in the secondary circuit, which each allow the most favorable adaptation of the microphone arrangement to the given LF circuit of the relevant receiver. Anspruch 2: Übertrager-Zusatz nach Anspruch 1, dadurch gekennzeichnet, daß der Übertrager zusammen mit der verwendeten Stromquelle des Mikrophons in einem Gehäuse vereinigt ist.Claim 2: Transmitter add-on according to Claim 1, characterized in that the transmitter is combined in one housing together with the current source used for the microphone.
