Abstract
Die Erfindung betrifft einen Titanschalltrichter für Folgetonhörner, Sirenen und Hupen. Durch die Verwendung von Titan oder einer Titanlegierung für Schalltrichter werden die erzeugten Schwingungen nicht gedämpft, sondern die Ansprache, Tragfähigkeit und die Brillanz eines Folgetonhorns, einer Sirene und einer Hupe wesentlich verbessert.Sowohl Titan als auch die Titanlegierungen als auch die PVD-Beschichtungen sind inert. Die Titanschalltrichter können mit TiN oder CrC oder CrN im PVD Verfahren beschichtet sein.The invention relates to a titanium horn for secondary tone horns, sirens and horns. The use of titanium or a titanium alloy for horns does not dampen the vibrations generated, but rather improves the response, load-bearing capacity and the brilliance of a secondary tone horn, a siren and a horn. Both titanium and the titanium alloys as well as the PVD coatings are inert , The titanium sound funnels can be coated with TiN or CrC or CrN in the PVD process.
Description
<Desc/Clms Page number 1>
Die Erfindung betrifft einen Schalltrichter für Folgetonhömer, Sirenen und Hupen. Ein
Schalltrichter ist ein rotationsymetrisches Werkstück, das dazu dient Schallwellen über einen Trichter zu verstärken.
Der Schall wird durch die kleine Öffnung 1 in den Trichter eingeleitet und dann, durch den immer grösser werdenden Luftquerschnitt bei der Austrittsöffnung 2, verstärkt.
Dabei kommt der Trichter selbst in Schwingung.
Normalerweise wird der Trichter aus Stahlblech oder Kunststoff gefertigt.
Die Erfindung beruht darauf, das anstatt von dämpfenden Materialien wie Stahlblech oder Kunststoff Titan oder eine Titanlegierung verwendet wird.
Der Trichter aus Titan oder einer Titanlegierung kann mit Titannitrid ( TiN), Chromnitrid ( CrN ) oder Chromkarbid ( CrC ) beschichtet werden und zwar in einem physikalischen Aufdampfungsverfahren, kurz PVD genannt. Sowohl die Legierung selbst, als auch die mit TiN oder CrC oder CrN beschichtete Legierung sind inert und korrodieren unter normalen Bedingungen, auch bei Meereswasser nicht ; Allergien sind bekannt.
Durch die sehr leicht in Schwingung zu versetzende Titanlegierung hat der Titanschalltrichter eine sehr leicht Ansprache und einen brillanten obertonreichen Ton.
Dadurch ist der erzeugte Schall weiter hörbar und durchdringender.
Mit weniger Energie kann im Vergleich mit herkömmlichen Schalltrichtern ein gleich lauter Schall erzeugt werden.
Der Titanschalltrichter kann an der grossen Öffnung auch einen Verstärkungswulst 3 haben.
In der Figur ist ein Schalltrichter Teilweise im Schnitt dargestellt.

The invention relates to a horn for secondary sounders, sirens and horns. On
Sound funnel is a rotationally symmetrical workpiece that is used to amplify sound waves via a funnel.
The sound is introduced into the funnel through the small opening 1 and then amplified by the increasingly larger air cross-section at the outlet opening 2.
The funnel itself starts to vibrate.
The funnel is usually made of sheet steel or plastic.
The invention is based on the fact that titanium or a titanium alloy is used instead of damping materials such as sheet steel or plastic.
The funnel made of titanium or a titanium alloy can be coated with titanium nitride (TiN), chromium nitride (CrN) or chromium carbide (CrC) in a physical vapor deposition process, abbreviated to PVD. Both the alloy itself and the alloy coated with TiN or CrC or CrN are inert and do not corrode under normal conditions, even with sea water; Allergies are known.
Due to the very easy to vibrate titanium alloy, the titanium horn has a very easy response and a brilliant tone rich in overtones.
As a result, the sound generated is more audible and penetrating.
Equally loud sound can be generated with less energy compared to conventional horns.
The titanium sound funnel can also have a reinforcing bead 3 at the large opening.
In the figure, a bell is partially shown in section.
