  Sprechapparat. 



   Vorliegende Erfindung ist dadurch gekennzeichnet, dass in   eiuöu   den Resonanzkasten eines trichterlosen Grammophons vollständig abschliessenden   Holzdec1iel   ein   Kohlenkörner-   mikrophon eingefügt und letzteres mittels Zweigleitung an eine mit Gleichstrom betriebene Bogenlampe angeschlossen wird. Der Anschluss erfolgt in bekannter Weise nach den Angaben des Entdeckers der sprechenden Bogenlampe H. Th. Simon im Jahre 1898 bzw. nach der   nachträglichen Verbesserung   durch W. Duddell. 



   Durch   Abschluss   des Resonanzkastens, in welchen die Schalleitung des Grammophons mündet, wird zweierlei erreicht, und zwar einerseits die Abdämpfung der Sprache für die nächste Umgehung und andererseits vorgebeugt, dass nichts von der Sprache verloren geht, sondern dass dieselbe mit vollem Klang auf das im   Abschlussdeckel eingefügte   Mikrophon einwirkt und von da zur Bogenlampe an entfernter Stelle ungeschwächt geleitet werden kann. 



   Die Erfindung stellt den ersten Versuch dar, sprechenden Bogenlampen eine praktische Verwendung, z. B. zu Reklamezwecken, zu gehen.

   The present invention is characterized in that a carbon grain microphone is inserted into a wooden cover that completely closes off the resonance box of a funnelless gramophone and the latter is connected to an arc lamp operated with direct current by means of a branch line. The connection is made in the known way according to the information provided by the discoverer of the speaking arc lamp H. Th. Simon in 1898 or after the subsequent improvement by W. Duddell.



   By closing the resonance box, into which the sound line of the gramophone flows, two things are achieved: on the one hand, the attenuation of the language for the next bypass and, on the other hand, it prevents that nothing of the language is lost, but that the same with full sound on the cover The inserted microphone acts and can be passed from there to the arc lamp at a distant point without being weakened.



   The invention is the first attempt to put talking arc lamps into practical use, e.g. B. for advertising purposes to go.

PATENT-ANSPRUCH : Sprechapparat, bestehend aus einer Verbindung einer sprechenden Bogenlampe mit einem Grammophon, dadurch gekennzeichnet, dass der Resonanzkaston eines trichtertosen Grammophons von allen Seiten geschlossen erscheint und im Zentrum der der Schallleitung entgegenliegenden Holzwand ein empfindliches Mikrophon eingefügt wird, wobei das Mikrophon überdies in bekannter Weise an e) ne etektrischc Bogenlampe mittels Zweigleitung zu dem Zweck angeschlossen wird, um den Text von Grammophonplatten an entfernten Stellen durch die Bogenflamme reproduzieren zu können. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Speaking apparatus, consisting of a connection between a speaking arc lamp and a gramophone, characterized in that the resonance box of a funnel-like gramophone appears closed on all sides and a sensitive microphone is inserted in the center of the wooden wall opposite the sound line, the microphone also being connected to e ) ne electric arc lamp is connected by means of a branch line for the purpose of being able to reproduce the text of gramophone records at distant places through the arc flame. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
