 miteinander erfolgt durch Eingreifen eines mit einem Gewinde versehenen Stutzens 24 in ein Auge   26,   wobei zugleich der Hebelarm 8 im Loch 26 festgehalten wird. Zwischen den beiden Elektroden einer Kammer 16 sind in bekannter Weise Kohlenkörner, die zur   Veränderung   des Widerstandes dienen, angeordnet. Die Ringe 14 und die Zylinder 15 sind durch Schrauben 27 verbunden und ziemlich stark gehalten, um die Wärme von den Kammern 16 vollständig abzuleiten, welche durch den   verstärkten   Strom hervorgerufen wird. 



   Die   Kühlung   der Zylinder wird entweder durch   strahlenförmig auseinanderlaufende   Kühlplatten oder durch Wasserkühlung bewirkt. Im vorliegenden Falle wurde die   letzterss Aus-

 zur Versteifung der Ringe   14   dienenden Rippen 30, durch welche hindurch die Ein-und Ausflussröhren 31, 32 für eine geeignete   Wasserergänxung geführt sind.   Auf die Aussenseite der Ringe   14   sind Dichtungsringe 33 zur Abdichtung der nach aussen offenen Kanäle 28 aufgelegt, welche durch die mittels Innengewindes aufgeschraubten Deckelringe 34 in ihrer Lage festgehalten werden. 



     Die Flanschen j ?   sind mit der Grundplatte 2 durch Schrauben   3. 5 verbunden, welche durch  
Isolationshülsen 36 hindurchgreifen. Diese bestehen aus Elfenbein oder aus ähnlichem Isolier- material, das für Temperatur-und Wetterschwankungen nicht empfänglich ist. Eine Schutz- kappe 37 wird von unten her über den Apparat geschoben und an der   Platte 2 angeschraubt  
Eine runde Platte 38 endlich schliesst die Rückseite des Ringes 1 ab und ist mit einer Aus- buchtung 39 versehen, in deren Innenraum der Hebelarm 7 genügend freien Spielraum hat   PATENT-ANSPRÜCHE:   1. Lautsprechendes Mikrophon, bei welchem die Schwingungen der Membrane auf zwei

 with each other by engaging a threaded connector 24 in an eye 26, the lever arm 8 being held in the hole 26 at the same time. Between the two electrodes of a chamber 16 carbon grains, which are used to change the resistance, are arranged in a known manner. The rings 14 and the cylinders 15 are connected by screws 27 and are held quite strong in order to completely dissipate the heat from the chambers 16 which is caused by the increased flow.



   The cylinders are cooled either by radiating cooling plates or by water cooling. In the present case, the latter was

 ribs 30 which serve to stiffen the rings 14 and through which the inflow and outflow pipes 31, 32 are guided for a suitable water supplement. On the outside of the rings 14, sealing rings 33 are placed to seal the outwardly open channels 28, which are held in their position by the cover rings 34 screwed on by means of an internal thread.



     The flanges j? are connected to the base plate 2 by screws 3. 5, which through
Reach through insulation sleeves 36. These consist of ivory or a similar insulating material that is not susceptible to temperature and weather fluctuations. A protective cap 37 is pushed over the apparatus from below and screwed onto the plate 2
A round plate 38 finally closes the back of the ring 1 and is provided with a bulge 39, in the interior of which the lever arm 7 has enough free space. PATENT CLAIMS: 1. Loudspeaker microphone in which the diaphragm vibrates to two

 To make the membrane ineffective and to prevent the reproduction of impure sounds.

 

Claims (1)

2.
