Description
Die Erfindung hat eine neuartige federnde Lagerung aus hochelastischem Material für schwingende Systeme zum Gegenstand, die zumal bei Antriebssystemen für Lautspreeher wertvoll ist, indem sie ausgeprägte Eigenschwingungen nicht zur Wirkung kommen läßt. Die neue Federung oder Halterung wird mit Vorteil bei in sich starr schwingenden Körpern angewendet, also z. B. bei Magnetankern, und zwar besonders bei stabiörmigen Ankern, die parallel zu sich, also rechtwinklig zu ihrer Längsachse schwingen. Gemäß der Erfindung wird die Federung nicht wie bisher üblich aus Metall — meist dem gleichen Material wie das schwingende System selbst — hergestellt, sondern es werden dazu Stoffe wie Hartgummi, Fiber, Horn, Schildpatt, Elfenbein und ähnliche nicht metallische, harte und hochelastische Materiaao Hen verwendet. Diese Stoffe besitzen durchweg eine größere innere Dämpfung als Metalle, so daß sich Eigenfrequenzen bei weitem nicht so stark ausprägen können. Auf diese Weise wird die Klangfarbe von Tönen — wenn es sich um Tonmembranen handelt — weicher und natürlicher und verliert ihren spitzen Metallcharakter.The invention has a new type of resilient mounting made of highly elastic material for vibrating systems to the subject, especially in drive systems for loudspeakers is valuable in that it does not allow pronounced natural vibrations to have an effect. The new suspension or bracket is used with advantage in rigidly oscillating bodies, so z. B. for magnet armatures, especially with rod-shaped anchors that are parallel to themselves, i.e. swing at right angles to its longitudinal axis. According to the invention, the suspension not made of metal, as was previously the case - mostly the same material as the vibrating one System itself - manufactured, but materials such as hard rubber, fiber, horn, Tortoiseshell, ivory and similar non-metallic, hard and highly elastic materiaao Hen used. These substances consistently have greater internal damping than metals, so that natural frequencies can not be so pronounced by far. To this The timbre of tones - when it comes to tone membranes - is wise softer and more natural and loses its sharp metal character.
Die federnden Teile der Lagerung werden erfindungsgemäß in Form eines Steges hergestellt, dessen Querschnitt von Kanten begrenzt ist, deren Verlauf den Kurven gleicher Biegemomente angepaßt sind. Auf diese Weise wird eine allzu starke Dämpfung des Systems vermieden.The resilient parts of the storage are manufactured according to the invention in the form of a web, whose cross-section is limited by edges, the course of which is adapted to the curves of equal bending moments. To this In this way, excessive damping of the system is avoided.
In der Zeichnung sind zwei Ausführungen des Gegenstandes der Erfindung beispielsweise dargestellt.In the drawing, two embodiments of the subject matter of the invention are for example shown.
In Abb. ι ist eine einfache AusführungIn Fig. Ι is a simple design
eines federnden Lagersteges gezeigt. Dieser besteht aus einer Doppel-T-förmigen Platte f, beispielsweise aus Fiber, die an äußeren Rändern r, r fest eingespannt ist. In der Mitte ist sie durch einen Stift ν mit einer Membran m verbunden. Von der Membran m ist nur der mittlere Teil dargestellt, und es ist freigelassen und für die Erfindung unwesentlich, wie die Membran an ihren äußeren Kanten eingespannt ist. Die Kanten k des stegartigen Teiles der Lagerplatte sind der Form der Kurve der gleichen Biegemomente angepaßt.a resilient bearing web shown. This consists of a double-T-shaped plate f, for example made of fiber, which is firmly clamped at the outer edges r, r. In the middle it is connected to a membrane m by a pin ν . Only the middle part of the membrane m is shown, and it is left blank and unimportant for the invention how the membrane is clamped at its outer edges. The edges k of the web-like part of the bearing plate are adapted to the shape of the curve of the same bending moments.
Die Lagerplatte kann auch an nur einem Rande r befestigt sein, wobei die andere Hälfte wegfällt und das Verbindungsstück ν somit mit dem Ende der Feder verbunden ist.The bearing plate can also be attached to only one edge r , the other half being omitted and the connecting piece ν thus being connected to the end of the spring.
Abb. 2 veranschaulicht ein doppeltes Federsystem /, /; die Federn sind beispielsweise durch einen Magnetanker a, der sich etwa in einer Spule s (gestrichelt gezeichnet) befindet, miteinander verbunden und ermöglichen so dessen Bewegung in Richtung seiner Ouerausdehnung unter Parallelbleiben seiner Längsachse.Fig. 2 illustrates a double spring system /, /; the springs are, for example, connected to one another by a magnet armature a, which is located approximately in a coil s (shown in dashed lines) and thus enable its movement in the direction of its cross-extension while its longitudinal axis remains parallel.
Die Erfindung ist für zahlreiche Schwingsysteme verwendbar, in erster Linie für Anker von Mikrophonen, Lautsprechern und anderen tonerzeugenden Instrumenten, ferner für Summer und Oszillographen, endlich z. B. auch für Hammersysteme bei elektrisch betriebenen Musikinstrumenten usw.The invention can be used for numerous vibratory systems, primarily for anchors of microphones, loudspeakers and other sound-generating instruments, also for buzzers and oscilloscopes, finally z. B. also for hammer systems in electrically operated musical instruments etc.
