Hörrohr.Ear tube.
Diese Erfindung betrifft ein Hörrohr, welches zum Zwecke der Vermehrung und Verstärkung des Schalles in das Ohr eingesetzt werden soll.This invention relates to an ear trumpet which, for the purposes of augmentation and amplification of the sound should be inserted into the ear.
Fig. ι zeigt eine perspectivische Ansicht des Instrumentes in vergröfsertem Mafsstabe; Fig. 2 ist der Grundrifs des Hörrohrs; Fig. 3 stellt einen Querschnitt der Vorrichtung dar.Fig. Ι shows a perspective view of the Instrument on a larger scale; Fig. 2 is the outline of the ear trumpet; Fig. 3 represents a cross section of the device.
An dem einen Ende des Instrumentes befindet sich ein kleiner concaver Teller α von etwa 10 mm Gröfse. Diese kleine Schale bildet den äufseren Schallempfänger und kann dieselbe entweder von Gold oder von einem anderen entsprechenden Metall angefertigt sein. Auf drei Seiten hat diese Schale Ausschnitte, im Centrum befindet sich ein Loch b von etwa 4 mm im Durchmesser. Die concave Fläche der Schale kann mit fleischfarbenem Email überzogen sein, damit man sie weniger bemerkt. Eine kleine Röhre c geht von dem Loch b im Mittelpunkt der Schale aus. Am entgegengesetzten Ende des Instrumentes befindet sich eine dünne Gummischeibe d von ungefähr. 8 mm im Durchmesser.At one end of the instrument there is a small concave plate α of about 10 mm in size. This small bowl forms the outer sound receiver and can be made either of gold or of another suitable metal. This bowl has cutouts on three sides, in the center there is a hole b about 4 mm in diameter. The concave surface of the bowl can be covered with flesh-colored enamel so that it is less noticeable. A small tube c extends from the hole b in the center of the bowl. At the opposite end of the instrument is a thin rubber disk d of approximately. 8 mm in diameter.
Diese beiden Theile sind unter einander durch einen feinen Draht e verbunden, welcher vorzugsweise aus vergoldetem Stahl oder auch aus einem anderen entsprechenden Material bestehen kann. Die Verbindungsstelle des Drahtes e mit der Scheibe d ist mittelst Scheiben ff verstärkt; auf jeder Seite der Scheibe d liegt eine dieser Scheiben f. Der Draht e ist an das Röhrchen c gelöthet und endet am Loch b. These two parts are connected to one another by a fine wire e , which may preferably consist of gold-plated steel or some other suitable material. The junction of the wire e with the disk d is reinforced by disks ff; One of these disks f lies on each side of the disk D. The wire e is soldered to the tube c and ends at the hole b.
Das so gestaltete Hörrohr wird in den äufseren Gehörgang eingeführt, mit der Gummischeibe d nach innen gerichtet; die kleine Schale α steht aufserhalb des Ohres, nahe dem letzteren. Das Instrument schliefst im Ohr die Wände des Gehörganges vollständig ab und schiebt die Knorpel zur Seite, während der Schallempfänger alle Schall- und Luftwellen im •verstärkten Mafse übermittelt, und zwar durch das Röhrchen c und die Gummischeibe d. The auditory tube designed in this way is inserted into the external auditory canal with the rubber washer d facing inwards; the small cup α stands outside the ear, close to the latter. The instrument closes the walls of the auditory canal in the ear completely and pushes the cartilage aside, while the sound receiver transmits all sound and air waves to an amplified degree, namely through the tube c and the rubber washer d.
