Description
Profilmembran für Lautsprecher. Profilmembranen wurden bisher so herge stellt, dass dünne Scheibchen aus Metall der art gepresst wurden, dass an der einen Fläche Erhöhungen und an der entgegengesetzten Fläche die entsprechenden Vertiefungen ent standen. Diese Membranen haben Nachteile. Das Material muss sehr dünn gewählt werden, weil durch das Profil Versteifungen entstehen, so dass die Membran nicht mehr elastisch ge nug ist, wenn nicht ganz dünnes Material verwendet wird. Bei starker mechanischer In anspruchnahme zerreisst jedoch die Membran mit solch dünnem Material.
Um diesen Übelständen zu steuern, besteht die erfindungsgemässe Membran aus einer ebenen Scheibe, auf deren einen oder beiden Flächen ein Profilstück aufgesetzt und be festigt ist.
Im folgenden ist anhand der Zeichnung ein Ausführungsbeispiel der erfindungsgemä ssen Membran beschrieben.
In Fig. 1 ist eine flache Scheibe in An sicht von oben und im Querschnitt, in Fig. 2 einkreisrundes Profilstück ebenfalls in Ansicht von oben und im Querschnitt und in Fig. 3 die fertige Membran mit aufgesetztem Profil stück dargestellt.
Die Membran wird aus einem flachen Scheibchen, auf welches das Profilstück auf gesetzt wird, hergestellt. Die Verbindung des Scheibchens mit dem Profilstück erfolgt durch eine der bekannten Befestigungsarten, wie zum Beispiel Kleben, Schrauben, Befestigungs ösen usw. Das Material für das Profil wird vorteilhaft flexibel oder elastisch sein, damit es die Schwingungen des Scheibchens mit macht und nicht abreisst. An der Membran kann eine Schwingspule irgendwie befestigt sein.
Profile membrane for loudspeakers. Up to now, profile membranes have been manufactured in such a way that thin metal discs were pressed in such a way that elevations were created on one surface and the corresponding depressions on the opposite surface. These membranes have disadvantages. The material must be selected to be very thin, because the profile creates stiffening, so that the membrane is no longer elastic enough if not very thin material is used. However, under severe mechanical stress, the membrane with such a thin material tears.
In order to control these inconveniences, the membrane according to the invention consists of a flat disc, on one or both surfaces of which a profile piece is placed and fastened.
An exemplary embodiment of the membrane according to the invention is described below with reference to the drawing.
In Fig. 1 a flat disc is in view from above and in cross section, in Fig. 2 a circular profile piece also in view from above and in cross section and in Fig. 3, the finished membrane with the profile piece is shown.
The membrane is made from a flat disc on which the profile piece is placed. The connection of the disc with the profile piece is done by one of the known types of fastening, such as gluing, screws, fastening eyelets, etc. The material for the profile is advantageously flexible or elastic so that it makes the vibrations of the disc with and does not tear off. A voice coil can be somehow attached to the diaphragm.
