Description
verteilten Prägungendistributed embossings
Es ist bereits vorgeschlagen wordeq, für Schallapparate große und versteifte" Membranen zu benutzen. Gemäß der Erfindung kann man eine genügende Steifigkeit erzielen, wenn man die Membran derart mit Prägungen versieht, daß jede senkrecht zur Membran stehende Schnittebene mehrmals die erhabenen und vertieften Teile der Membran durchquert. Die Abbildungen zeigen Ausführungsbeispiele der Erfindung·.' In den Abb. 1 und 2 ist in Grundriß und Schnitt ein Teil einer Membran dargestellt, die mit kreisförmigen Prägungen versehen ist. Die Prägungen sind derart gegeneinasder versetzt, daß die Räume zwischen den in einer Geraden liegenden Vertiefungen durch die folgende Reihe verdeckt werden. Es wird dadurch erreicht, daß jeder durch die Membran führende Schnitt mehrere Prägungen durchquert.It has already been suggested for wordeq Sound apparatus to use large and stiffened "diaphragms. According to the invention can sufficient rigidity can be achieved if the membrane is embossed in such a way that that each cutting plane perpendicular to the membrane traverses the raised and depressed parts of the membrane several times. The figures show exemplary embodiments of the invention '.' In Figs. 1 and 2 is shown in plan and section a part of a membrane with circular Embossing is provided. The embossing is offset in relation to one another in such a way that the spaces hidden between the depressions lying in a straight line by the following row will. It is achieved that each cut leading through the membrane several Embossings crossed.
to Die Abb. 3 und 4 zeigen ein weiteres Ausführungsbeispiel der Erfindung in Grundriß und Schnitt. Die Prägungen sind sechseckförmig gestaltet und entsprechen im übrigen den kreisförmigen Prägungen in Abb.i und 2. Die Abb. 5 und 6 zeigen einen Teil einer Membran in Grundriß und Schnitt, die mit H-förmigen Prägungen versehen ist, und zwar ebenfalls derart, daß jeder durch die Membran führende Schnitt die Erhebungen und Vertiefungen mehrmals durchquert.to Figs. 3 and 4 show a further embodiment of the invention in plan and cut. The embossments are hexagonal and otherwise correspond the circular embossing in Fig.i and 2. Figs. 5 and 6 show part of a Membrane in plan and section, which is provided with H-shaped embossing, namely also in such a way that each cut leading through the membrane defines the elevations and depressions crossed several times.
Die Anordnung von Prägungen gemäß der Erfindung ist besonders vorteilhaft, weil zur Versteifung der Membran keine besonderen Rippen benötigt werden, die das Gesamtgewicht der Membran erhöhen.The arrangement of embossments according to the invention is particularly advantageous because for Stiffening the diaphragm does not require any special ribs that account for the total weight increase the membrane.
