Description

Die vorliegende Erfindung bezieht sich auf akustische Warnsignalvorrichtungen, und zwar insbeson-. dere auf derartige Warnvorrichtungen mit einem Elektromagnet, dessen Anker mit der Mitte einer Membran sowie mit einer Resonanzscheibe starr verbunden ist. Sie bezweckt, die Lautstärke dieser Apparate bei gleichem Platzbedarf und gleichem Energieverbrauch zu erhöhen.The present invention relates to audible warning signaling devices, and in particular. others on such warning devices with an electromagnet, whose anchor is rigidly connected to the center of a membrane and to a resonance disk is. Its purpose is to control the volume of these devices with the same space requirements and the same Increase energy consumption.

Dieses Ergebnis wird erfindungsgemäß dadurch erhalten, daß man der Resonanzscheibe eine Eigenfrequenz gibt, welche wenigstens angenähert ein ganzes Vielfaches der Frequenz der gesamten bewegten Teile ist. Man erhält so während des Arbeitens der Warnvorrichtung eine Resonanzerscheinung, welche die Aussendung eines Tones größter Lautstärke bei einer gegebenen elektromagnetischen Leistung bewirkt.According to the invention, this result is obtained by the Resonance disc gives a natural frequency, which is at least approximately a whole Is a multiple of the frequency of the entire moving parts. One obtains during the Working the warning device a resonance phenomenon, which the emission of a Tones causes the greatest volume for a given electromagnetic power.

In der Zeichnung ist als Beispiel der Schnitt einer Warnvorrichtung dargestellt.The drawing shows the section of a warning device as an example shown.

Der Elektromagnet r weist einen Anker 2 auf, der durch eine Stange 3 mit einer schwingenden Membran 4 und einer äußeren Resonanzscheibe 5 verbunden ist, welche wenigstens an ihrem Umfangsteil die Form eines Umdrehungsparaboloids oder eine benachbarte Form aufweist. Erfindungsgemäß gibt man der Resonanzscheibe 5 eine Eigenfrequenz, die annähernd gleich einem ganzen Vielfachen der Frequenz der Gesamtheit der bewegten Teile 2-3-4-5 ist. Wenn z. B. die Frequenz der Gesamtheit der bewegten Teile in der Größenordnung von 40o Hz liegt, muß die Frequenz der Scheibe 5 32oo Hz betragen, was einen für die Erzielung einer größten Schallwirkung sehr günstigen Wert darstellt.The electromagnet r has an armature 2, which is supported by a rod 3 connected to a vibrating membrane 4 and an outer resonance disk 5 is, which at least on its peripheral part has the shape of a paraboloid of revolution or has an adjacent shape. According to the invention, the resonance disk is given 5 is a natural frequency that is approximately equal to a whole multiple of the frequency of all moving parts is 2-3-4-5. If z. B. the frequency of the whole of the moving parts is in the order of 40o Hz, the frequency of the disk must be 5 32oo Hz, which is great for achieving the greatest sound effect represents favorable value.

Es ist selbstverständlich, daß man an der oben beschriebenen Ausführungsform Veränderungen vornehmen kann, ohne den Rahmen der Erfindung zu verlassen.It goes without saying that the embodiment described above Can make changes without departing from the scope of the invention.
