Sure is that the sound funnel of the loudspeaker is on a flange odor dorgl. the KomprojjordosG rests, that the middle funnel is supported with its opening against the inner surface dos Ausso nt, and that further means for door tensioning dos middle triohts rs gogon the InnGntrichtGr are provided Fastening of the individual funnels, for example, by means of a tiny, visible connection

Bin AusfühJungsbeispiel der .Neuerung ist in den Zeichnungen erläuterte Gsmäss Abb. 1 wird, dor mittlere Trichter M gqgen den Boden dsm äusseren Trichters A abgestützt; diese beiden Trichter— teile werden durch den Innontrichtor I zusammengezogen. Der äussere trichter erhält gemäss Abb." 1 eine Rille R, in djß Stützen St ß.es Trichters M eingreifen» Mit dom Trichter M verbunden ist der Inneiit rieht sr I und zwar z,B, durch Tor schraubung. Der Innontrich— tor weist an seinem vorderen Ende einen Steg mit einem Gewinde, auf, der zvan. "Vörschrauben des Mittelteiles mit dom Innentrichter mittels der Schraube S dient. Das Mittelteil hat an seinem unteren Ende einige - vorzugsweise 3 - Stützen St , mit denen os sich gegen die Hille B an dem Aussentoil A abstützt. Durch Anziehen der Schraube S werden die drei Trichterteile mit dom System B zu einem festen. Gebilde zusammengefügt* Bs empfiehlt sich, das Aussonteil an dem Rande, auf dom das System B aufliegt, zu durchlochon und dio Systemaasc&lüssG durch dioso Löcher hindurchzufuhren. Auf djßse Weiso siad die Systemanschliieso vorhältnisiiiäs sig gut geschützt. Die Loitungon L führen nun auf der Innenseite von A entweder zu KLommen P und von dort durch eine Durchführung nach ausson (Abb.2) oder aber von der Innenseite von A nach einem an A angebrachton odor dio Wand des Teiles A durchdringenden Kasten K, der dio Hemmen und gegebenenfalls den Überträger Ü enthält (Abb.5)Bin AusfühJungsbeispiel the .New is explained in the drawings according to Fig. 1, the middle funnel M is supported against the bottom of the outer funnel A; these two funnel parts are drawn together by the interior funnel I. The outer funnel obtained according to Fig. "1, a groove R, ß.es in djß supports St funnel M is engaged" With dom funnel M connected to the Inneiit Judges sr I namely z, B, by screw connection target. The target comprises Innontrich- at its front end a web with a thread, which is used to screw the middle part with the inner funnel by means of the screw S. The middle part has at its lower end some - preferably 3 - supports St, with which os is supported against the Hille B on the outer toilet A. By tightening the screw S, the three funnel parts with dome system B become one fixed. Structures put together * It is recommended that the external part on the edge on which system B rests, to be perforated and the system as & lüssG through dioso holes. In this way, the system connections are relatively well protected. The Loitungon L now lead on the inside of A either to KLommen P and from there through a passage to Ausson (Fig. 2) or from the inside of A to a box K that is attached to A or the wall of part A, the dio inhibition and possibly the carrier Ü contains (Fig.5)
