  Telephon mit konzentrisch angeordneten Polen. 



   Die Erfindung betrifft Telephone mit zwecks verstärkter Lautwirkung konzentrisch angeordneten Polen und aber den äusseren Pol hinaus verlängerter Membran. Diese Fernhörer wurden bis jetzt mit einem ring-oder hufeisenförmigen Magnet versehen, auf dem die Polschuhe aufgesetzt waren. 



   Gemäss der Erfindung ist der Magnet selbst als Topfmagnet ausgebildet in dessen Innenraum ein Eisenkern mit aufgesetzter Spule befestigt ist. 



   Eine Ausführungsform der Erfindung ist auf der Zeichnung in einem Vertikalschnitt dargestellt. 



   Zwischen der   Hörmuschel   a und einem daran durch Verschraubung befestigten Deckel b ist die Membran c eingesetzt, welche über die ringförmige Polfläche d des Topfmaguetes e hinausreicht. Dieser Topfmagnet der   halbkugel-oder kegelförmig   ausgebildet sein kann, ist teilweise oder ganz von dem Deckel b eingesctilossen. Innerhalb des   Topfmagnetes   befindet sich ein Eisenkern f, auf welchen eine kegelförmig gewickelte Spule g aufgesetzt ist.

  Telephone with concentrically arranged poles.



   The invention relates to telephones with poles arranged concentrically for the purpose of increased sound effect and a membrane which is extended beyond the outer pole. Up until now, these remote receivers have been provided with a ring-shaped or horseshoe-shaped magnet on which the pole pieces are placed.



   According to the invention, the magnet itself is designed as a pot magnet, in the interior of which an iron core with an attached coil is attached.



   An embodiment of the invention is shown in the drawing in a vertical section.



   The membrane c, which extends beyond the annular pole face d of the pot magnet e, is inserted between the earpiece a and a cover b fastened to it by screwing. This pot magnet, which can be hemispherical or conical, is partially or completely enclosed by the cover b. Inside the pot magnet there is an iron core f on which a conically wound coil g is placed.
