Description

Elektrische Hupe mit einer einen Luftraum einschließenden, von einem Elektromagneten beeinflußten Doppelmembran. Die Erfindung betrifft eine elektrische Hupe mit einer einen Luftraum einschließenden, von einem Elektromagneten beeinflußten Doppelmembran und ist dadurch gekennzeichnet, daß der Unterbrecherkontakt des elektro-. magnetischen Stromkreises an der von dem Elektromagneten entfernteren Membran liegt, um eine safte Auseinanderpressung der Kontakte infolge der Druckänderungen in dem eingeschlossenen Luftpolster zu erzeugen. Zur Regelung des Luftpolsters ist in an sich bekannter Weise eine regelbare Öffnung und zur Funkenlöschung an den Kontakten ein Kondensator vorgesehen. In der Zeichnung ist der Erfindungsgegenstand in beispielsweiser Ausführungs= form schematisch -dargestellt.Electric horn with an air space enclosing one from one Electromagnets influenced double diaphragms. The invention relates to an electrical Horn with one that encloses an air space and is influenced by an electromagnet Double membrane and is characterized in that the breaker contact of the electrical. magnetic circuit is located on the membrane farther away from the electromagnet, to force the contacts apart as a result of the pressure changes in the to generate enclosed air cushions. To regulate the air cushion, in is on As is known, there is an adjustable opening and spark extinction on the contacts a capacitor is provided. The subject of the invention is shown in the drawing in an exemplary embodiment = form schematically -shown.

Die vermittels des Ankers*z durch den Elektromagneten z zum Schwingen gebrachte Hauptmembran 3 ist mit einer ihr vorgelagerten, zur Tonerzeugung dienenden Unterbrechermembran 4 derart durch eine Abdichtung verbunden, daß zwischen beiden Membranen ein Luftpolster eingeschlossen ist.By means of the armature * z by the electromagnet z to vibrate The main membrane 3 is brought up with an upstream membrane that is used to generate sound Interrupter diaphragm 4 so connected by a seal that between the two An air cushion is enclosed in the membranes.

Wird nun die Membran 3 durch die Wirkung des Elektromagneten 2 nach aufwärts gezogen, so entsteht in dem Hohlraum eine Luftverdünnung, die Unterbrechermembran 4 biegt sich ebenfalls .durch und öffnet den Kontakt zwischen zwei Kontaktklötzen, von denen. ?der eine an der Membran 4, der andere an einem quer über die öffnung des Schalltrichters liegenden schmalen Steg 6 vorgesehen ist. Da hierdurch der Strom unterbrochen ist, schnellt die Membran 3 wieder zurück, schwingt infolge ihrer Trägheit über die ursprüngliche Lage durch und bewirkt, da die Unterbrechermembran 4 durch den sich wieder schließenden Kontakt gehindert ist, analog auszuschwingen, eine Verdichtung des zwischen den Membranen 3, 4 eingeschlossenen Luftpolsters.If now the membrane 3 by the action of the electromagnet 2 after When pulled upwards, a dilution of air arises in the cavity, the interrupter membrane 4 also bends and opens the contact between two contact blocks, of which. one on the membrane 4, the other on one across the opening of the horn lying narrow web 6 is provided. Thereby the current is interrupted, the membrane 3 snaps back and oscillates as a result of its inertia through the original position and causes the interrupter diaphragm 4 through the re-closing contact is prevented from swinging analogously, a Compression of the air cushion enclosed between the membranes 3, 4.

Die Bewegungsänderungen der Unterbrechermeanbran 4 erfolgen somit nicht unmittelbar, sondern durch Druckinderungen in dem eingeschlossenen Luftpolster, wodurch eine sehr sanfte Arpressung der Kontakte erzielt wird. Im Gegensatz zu den bekannten Konstruktionen werden mithin die Kontakte aufeinandergepreßt und nicht mehr aufeinandergeschlagen, wodurch naturgemäß von einer Abnutzung kaum gefprochen werden kann.The changes in movement of the breaker face 4 thus take place not immediately, but through pressure reductions in the enclosed air cushion, whereby a very gentle Arpressing of the contacts is achieved. In contrast to the known constructions, the contacts are therefore pressed together and not more beaten together, which of course means that there is hardly any talk of wear and tear can be.

Die Funkenlöschung an den Kontakten wird in bekannter Weise durch einen Kondensator 5 bewirkt.The spark quenching at the contacts is carried out in a known manner causes a capacitor 5.

In weiterer Ausbildung des Erfindungsgedankens kann die Wirkung des Luftpolster durch einen einstellbaren Luftkatarakt beliebig geändert werden, zu welchem Behufe an geeigneter Stelle des Membrangehäuses ein durch Stellschraube o. dgl. regelbarer Luftaustritt vorgesehen sein kann, der den Raum zwischen den Membranen mit der Außenluft verbindet.In a further development of the inventive concept, the effect of the Air cushions can be changed at will by an adjustable air cataract, too which means at a suitable point of the diaphragm housing by adjusting screw o. The like. Adjustable air outlet can be provided, which the space between the Connects membranes with the outside air.
