Description
<Desc/Clms Page number 1>
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.
