Description
Schutzscheibe für Wandlermembrane Die Erfindung betrifft eine Schutzscheibe für Wandlermembrane, die mit Schalldurchtrittsöffnungen versehen ist, vorzugsweise verwendet in der Fernsprechtechnik.Protective disk for transducer diaphragm The invention relates to a protective disk for transducer diaphragms that are provided with sound passage openings, preferably used in telephony.
Es ist bekannt, für Mikrofone gelochte Schutzscheiben zu verwenden, die die Gefahr einer mechanischen Beschädigung der Membran verringern sollen. Nachteilig hierbei ist, daß die Gefahr einer Beschädigung, z. B. durch Einstechen, von der Größe_ der Löcher abhängig ist. Diese Größe ist jedoch nicht beliebig zu verkleinern, da damit wegen der geringeren Möglichkeit des Schalldurchtritts auch der Abstand der Löcher zueinander verkleinert werden muß, wodurch die Stabilität der Schutzscheibe stark leidet.It is known to use perforated protective disks for microphones, which are intended to reduce the risk of mechanical damage to the membrane. The disadvantage here is that the risk of damage, eg. As by piercing, depending on the size of the holes is _. However, this size cannot be reduced at will, since because of the reduced possibility of sound penetration, the distance between the holes must also be reduced, which greatly affects the stability of the protective pane.
Weiter sind Schutzscheiben bekannt, die, fächerföxmig gestanzt und gebogen, ebenfalls keinen absoluten Schutz gegen Einstiche gewährleisten. Außerdem besteht hierbei die Gefahr, die Fächer mechanisch zurückzubiegen, wodurch die Qualität des Mikrofons stark leiden würde.Protective disks are also known that are punched and fan-shaped curved, also do not guarantee absolute protection against punctures. aside from that there is a risk of mechanically bending back the compartments, which reduces the quality of the microphone would suffer greatly.
Aufgabe der Erfindung ist es, eine Schutzeinrichtung für eine Mikrofonmembran zu schaffen, die die Gefahr einer mechanischen Beschädigung der Membran verhindert, Wassertropfen, die beim Besprechen des Mikrofons auf die Schutzeinrichtung gelangen, abhält und selbst gegen mechanische Beschädigung weitgehend unempfindlich ist.The object of the invention is to provide a protective device for a microphone diaphragm to create that prevents the risk of mechanical damage to the membrane, Drops of water that get onto the protective device when talking to the microphone, and is largely insensitive to mechanical damage.
Diese Aufgabe wird dadurch gelöst, daß durch Schlitze in der Scheibe mehrere Abschnitte gebildet sind, die abwechselnd in verschiedenen Ebenen übereinander liegen, so daß die Schalldurchtrittsöffnungen in senkrecht zu der Scheibenebene verlaufenden Ebenen liegen.This object is achieved in that through slots in the disc several sections are formed, which alternate in different levels one above the other lie so that the sound passage openings in perpendicular to the plane of the disc lying planes.
Die Erfindung wird an Hand der F i g. 1 und 2 in einem Beispiel näher erläutert.The invention is illustrated with reference to FIGS. 1 and 2 in an example explained.
F i g. 1 zeigt die Draufsicht auf die Schutzscheibe, wobei die radialen Kanten der Schlitze S sichtbar werden; F i g. 2 zeigt den Schnitt von A-B.F i g. 1 shows the top view of the protective disk, the radial Edges of the slots S become visible; F i g. 2 shows the section from A-B.
Dabei ist W der Abstand zwischen der Ebene M der wirksamen Membranfläche und der Ebene E der Schutzscheibe. Die durch die radiale Schlitzung der Schutzscheibe entstandenen Sektoren sind abwechselnd nach oben O und nach unten U aus der Ebene E der Schutzscheibe herausgedrückt. Der nicht geschlitzte Rand R der Schutzscheibe ragt so weit über die Ebene E der Scheibe hinaus, daß er mit den nach oben gedrückten Sektoren O eine neue Ebene bildet.W is the distance between the plane M of the effective membrane area and the plane E of the protective screen. The through the radial slots in the protective disk resulting sectors are alternating upwards O and downwards U from the plane E of the protective screen pressed out. The non-slotted edge R of the protective disc protrudes so far beyond the plane E of the disc that it is pushed up with the Sectors O forms a new level.
