Patentansprüche:Patent claims: 1. Zentrierungsvorrichtung für die zylindrische Schwingspule von dynamischen Lautsprechern, welche mittels zweier in der Achsrichtung der Spule versetzter Traversen geführt wird, dadurch gekennzeichnet, daß mindestens eine der Traversen an ihrem inneren Umfang' mit gegeneinander versetzten Aussparungen solcher Bemessung versehen ist, daß Stege eingeführt werden können, deren Stärke dem nach dem Einsetzen der Spule verbleibenden Luftspalt des Systems entspricht.1. Centering device for the cylindrical voice coil of dynamic Loudspeakers, which are guided by means of two traverses offset in the axial direction of the coil, characterized in that, that at least one of the crossbars on its inner circumference 'with each other offset recesses is provided such dimensioning that webs can be introduced, the strength of the corresponds to the remaining air gap in the system after the coil has been inserted. 2. Zentriervorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Stege miteinander verbunden oder an einem gemeinsamen Träger angeordnet sind.2. Centering device according to claim 1, characterized in that the webs connected to one another or arranged on a common carrier. */ Von dem Patentsucher ist als der Erfinder angegeben worden: * / The patent seeker stated as the inventor: Erich Lampel in Radeberg, Sa.Erich Lampel in Radeberg, Sa.
