Description

Mitschwinger an elektromagnetischem Signalinstrument Es ist bekannt, bei Signalinstrumenten, insbesondere bei Tellerhörnern für Kraftfahrzeuge, zur Verbesserung der akustischen Verhältnisse an der Membran einen Mitschwinger anzuordnen. Es haben sich hauptsächlich Mitschwinger bewährt, die als rechteckiger Schwingbalken oder als kreisförmige Schwingscheibe ausgebildet sind. Es ist weiterhin bekannt, solchen Mitschwingern durch gewisse Querschnittsveränderungen eine größere Elastizität bzw. eine bestimmte Eigenfrequenz zu geben.Oscillator on electromagnetic signal instrument It is known with signal instruments, especially with horns for motor vehicles, for improvement to arrange a co-oscillator of the acoustic conditions on the membrane. Have it Mainly co-oscillators that have proven themselves as a rectangular oscillating beam or are designed as a circular oscillating disk. It is still known such Swinging through certain changes in cross-section results in greater elasticity or to give a certain natural frequency.

Die Erfindung betrifft einen Mitschwinger mit annähernd rechteckiger Ausdehnung, dessen Raumform besondere Vorteile ergibt. Der Erfindungsgegenstand ist gekennzeichnet durch seine Z-ähnliche Formgebung dergestalt, daß das die Befestigungsbohrung aufweisende Mittelteil beiderseits in geschwächte Querschnittszonen übergeht, während die beiden sich anschließenden Ouerbalken als Masseschwerpunkte ausgebildet sind. Dabei besteht ein schwingungstechnisch günstiges Verhältnis zwischen dem Gesamtgewicht des Mitschwingers und den beiden seitlichen Masseschwerpunkten.The invention relates to a co-oscillator with an approximately rectangular Expansion, the shape of which gives particular advantages. The subject of the invention is characterized by its Z-like shape in such a way that the mounting hole having central part merges into weakened cross-sectional zones on both sides, while the two adjoining crossbars are designed as centers of gravity. In terms of vibration, there is a favorable relationship between the total weight of the co-oscillator and the two lateral centers of gravity.

Die Erfindung zeigt weiterhin einen Weg zu besonders wirtschaftlicher Fertigung eines solchen Mitschwingers, der nicht nur die geforderten schwingungstechnischen Voraussetzungen erfüllt, sondern der darüber hinaus eine solche Umrißform besitzt, daß er sich verlustlos aus Streifenmaterial in der Weise stanzen läßt, daß bei jedem Arbeitsgang ein zweites ebensolches Werkstück mit anfällt. Diese in besonders glücklicher Weise gelungene Kombination der schwingungstechnischen Forderungen mit den fertigungstechnischen Möglichkeiten ergibt die erfindungsgemäß Z-ähnliche Körperform des Mitschwingers, dessen eigenwillige Gestalt sich außerdem recht günstig in die Gesamtanordnung eines elektromagnetischen Signalinstrumentes, z. B. eines Tellerhornes, einfügt.The invention also shows a way to be particularly economical Manufacture of such a co-oscillator, which not only provides the required vibration technology Meets the requirements, but which also has such an outline shape, that it can be punched losslessly from strip material in such a way that with everyone A second work piece of the same type is also required. These in particularly happier A wise, successful combination of the vibration-related requirements with the production-related ones The Z-like body shape of the co-oscillator according to the invention results in possibilities, its idiosyncratic shape also fits in quite favorably with the overall arrangement of a electromagnetic signal instrument, e.g. B. a plate horn, inserts.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung, und zwar zeigt Abb.1 die äußere Form des Mitschwingers und seine Lage in einem Tellerhorn, während Abb. 2 das verlustlose Stanzen erläutert.The drawing illustrates an embodiment of the invention, Figure 1 shows the external shape of the co-oscillator and its position in a cup horn, while Fig. 2 explains the lossless punching.

Der Mitschwinger 1 ist aus Flachmaterial in der Weise gestaltet, daß an seinen beiden Enden die Masseschwerpunkte 2 gebildet sind, die über die Querschnittsverengungen 3 mit dem Mittelabschnitt 4 zusammenhängen. Die einzelnen Abmessungen sind dabei so gewählt, daß einerseits die Form der Flächen 2 vollkommen mit der der Ausbrüche 5 übereinstimmt und andererseits ein schwingungstechnisch günstiges Verhältnis zwischen dem Gesamtgewicht des Mitschwingers 1, den Massesch-Nverpunkten 2 und den Querschnittsverengungen 3 vorhanden ist. Die Abrundungen 6 sind der Kreisform des Tellerhorns 7 angepaßt, an dessen Membran 8 der Mitschwinger mittels der Bohrung 9 befestigt ist. Der Mitschwinger 1 läßt sich verlustlos aus dem Materialstreifen 10 in der Weise wirtschaftlich fertigen, daß beim Anstanzen der Teile 11, 13, 15 die dazwischenliegenden Teile 12, 14, 16 mit anfallen.The co-oscillator 1 is designed from flat material in such a way that the centers of mass 2 are formed at its two ends, which over the cross-sectional constrictions 3 are related to the middle section 4. The individual dimensions are included chosen so that on the one hand the shape of the surfaces 2 completely with that of the outbreaks 5 matches and on the other hand, a favorable relationship between the total weight of the co-oscillator 1, the Massesch-Nver points 2 and the cross-sectional constrictions 3 is present. The roundings 6 are adapted to the circular shape of the crown horn 7, the co-oscillator is attached to its membrane 8 by means of the bore 9. The co-oscillator 1 can be manufactured economically from the material strip 10 without loss in such a way that that when punching the parts 11, 13, 15, the intermediate parts 12, 14, 16 with incurred.
