Description

Vorrichtung zur Regulierung der Tonhöhe und Dämpfung von Schallplatten. Gegenstand der Erfindung ist eine Vorrichtung zur Regulierung ,der Tonhöhe und Dämpfung von Schallplatten. Nach der Erfindhing ist die Schallplatte durch mehrere elastische Glieder mit dem starren Gehäuse so verbunden, daß durch die besondere Anordnung der elastischen Glieder deren Spannung verändert und die Ausbildung des Obertones der schwingenden Schallplatte begünstigt wird. Die Verbindungsglieder sind .dabei derart angeordnet, daß durdh ihre Angriffspunkte an .der Schallpliatte Schwingungsknoten bzw. -bäuche entstehen.Device for regulating the pitch and damping of records. The invention relates to a device for regulating the pitch and damping of records. According to the invention, the record is elastic due to several Links with the rigid housing so connected that by the special arrangement of the elastic links their tension changes and the formation of the overtone the vibrating record is favored. The connecting links are included arranged in such a way that their points of application at .der Schallpliatte vibration nodes or bellies arise.

Der Erfindungsgegenstand ist in der beiliegenden Zeichnung beispielsweise veranschaulicht.The subject of the invention is shown in the accompanying drawing, for example illustrated.

In einem Gehäuse C ist eine Schallplatte D eingespannt. An drei Stellen dieser Schallplatte greifen Schraubenfedern A, A1, AZ an, welche durch die Rückwand des Gehäuses C hindurchgehen und hier mit Muttern B versehen sind. Diese gestatten der Schallplatte eine beliebige Spannung zu erteilen.A record D is clamped in a housing C. At three points on this record, coil springs A, A1, AZ engage, which pass through the rear wall of the housing C and are provided with nuts B here. These allow the record to be given any tension.

Durch das Halten der Schallplatte an mehreren Stellen außer dem eingespannten Rand wird die Entstehung von Schwingungsknoten oder -bäuchen erleichtert, so daß Obertöne entstehen, welche durch die Muttern B in ihrer Höhe regelbar sind.By holding the record in several places besides the clamped one Edge facilitates the formation of nodes or antinodes, so that Overtones arise, the height of which can be adjusted by means of the nuts B.
