    Lautspreehender   telephonischer Wiedergabeapparat, insbesonders für mit einem Kinematographen gekuppelte Sprechmaschinen. 



   Erfindungsgegenstand ist ein lautsprechender telephonischer Wiedergabeapparat. ins- besonders zum Anschluss an eine mit einem Projektionsapparat verbundene Sprechmaschine, der vorteilhaft hinter dem Projektionsschirm angeordnet wird und sich von den bekannten
Vorrichtungen dieser Art dadurch unterscheidet, dass die in seinem Gehäuse angeordnete und mittels auf ihre Randteile wirkender Stellschrauben   künstlich gekrümmte   Membran in ihrer
Mitte einen pyramidenförmigen Ansatz besitzt, der durch eine Öffnung   im'Gehäuse   hindurch in Berührung mit der Nadel der wiedergebenden Schalldose tritt, so dass die Membran des
Telephons und die der Schalldose gleichmässig und unabhängig von der Einstellung der Elektro- magnete verstellbar sind. 



   In der Zeichnung ist Fig. i die Seitenansicht eines Projektionsapparates und einer damit verbundenen Sprechmaschine mit dem hinter dem Projektionsschirm angeordneten, an die
Sprechmaschine angeschlossenen Wiedergabetelephon gemäss der Erfindung und Fig. 2 ist ein
Schnitt durch das Wiedergabetelephon. 



   Mit einem   Projektionsapparat 10   bekannter Art ist in üblicher Weise eine Sprechmaschine verbunden, an die ein hinter dem Projektionsschirm angeordnetes Wiedergabetelephon an- geschlossen ist, das in einem Gehäuse 35 untergebracht ist, welches eine Membran 37 enthält. die durch auf ihre Randteile wirkende Stellschrauben 38 gekrümmt wird und in ihrer Mitte einen pyramidenförmigen Ansatz 39 besitzt, der durch eine Öffnung 40 im Gehäuse   35   in Berührung mit der Nadel 41 der wiedergebenden Schalldose   42   tritt.

    Loudspeaker telephonic reproducing apparatus, in particular for speaking machines coupled to a cinematograph.



   The subject of the invention is a loudspeaker telephone display device. in particular for connection to a speaking machine connected to a projection apparatus, which is advantageously arranged behind the projection screen and differs from the known ones
Devices of this type are distinguished by the fact that the membrane arranged in its housing and artificially curved by means of adjusting screws acting on its edge parts in its
Middle has a pyramid-shaped projection that comes through an opening in the housing in contact with the needle of the reproducing sound box, so that the membrane of the
Telephones and the sound box can be adjusted evenly and independently of the setting of the electromagnets.



   In the drawing, FIG. 1 is a side view of a projection apparatus and a speaking machine connected to it with the one arranged behind the projection screen, to which
Talking machine connected playback telephone according to the invention and Fig. 2 is a
Cut through the playback phone.



   With a projection apparatus 10 of known type, a speaking machine is connected in the usual way, to which a playback telephone arranged behind the projection screen is connected, which is accommodated in a housing 35 which contains a membrane 37. which is curved by adjusting screws 38 acting on its edge parts and has in its center a pyramid-shaped projection 39 which comes into contact with the needle 41 of the reproducing sound box 42 through an opening 40 in the housing 35.
