Description

Vorriditung zum Aufzeidinen von Tonsdiwingungen mittels eines Schwingelements Die Erfindung betriff t eine Vorrichtung zum Auf -zeichnen von Tonschwingungeri, bei welcher ein mit dem Schwingelernent verbundener Anker durch ein Magnetfeld im Rhythmus der aufzuzeichnen#&n Schwingungen, bewegt wird. Infolge der Hysterese folgt der Anker derartiger Geräte nicht genau den Schwingungen des magnetischen Feldes und kehrt inc,-besondere nicht genau in seine Nullpunktlage zurück.Provision for recording sound vibrations by means of a vibrating element The invention relates to a device for recording sound vibrations, in which an armature connected to the swing element is driven by a magnetic field in the Rhythm of the # & n vibrations to be recorded, is moved. As a result of the hysteresis the armature of such devices does not exactly follow the vibrations of the magnetic Field and does not return inc, -in particular, exactly to its zero point position.

Die Erfindung bezweckt, diesen Übelstand zu be- seitigen.The invention aims side this inconvenience to loading.

Gemäß der Erfindung wird, der Anker außerdem einem Magnetwechselfeld ausgesetzt. Die Frequenz dieses Wechselfeldes soll erheblich über der höchsten aufzuzeichnenden Frequenz liegen und so hoch sein, daß der Anker dliesen, Schwingungen mechanisch nicht mehr zu folgend vermag. Die Energie dieses Wechselfeldes liegt- zweckmäßig wenigstens in der Größenordnung der Energie desi tonfrequent gesteuerten Wechselfel(des, kam. aber mit, Vorteil erheblich größer sein. Es hat sich gezeigt, daß eine derartige Anordnung die oben geschilderten Nachteile nicht besitzt.According to the invention, the armature is also an alternating magnetic field exposed. The frequency of this alternating field should be considerably higher than the highest to be recorded Frequency lie and be so high that the anchor dliesen, vibrations mechanically can no longer follow. The energy of this alternating field is appropriate at least in the order of magnitude of the energy of the alternating field controlled by audio frequency (des, came. but with that advantage be considerably greater. It has been shown that such Arrangement does not have the disadvantages outlined above.

PATENTANSPRUCH: Vorrichtung zum Aufzeichnen, von Tonschwingungen mittels eines Schwingelements, welches mit einem Anker verbunden, ist, der durch ein Magnetfeld im Rhythmus der aufzuzeichnendenSchwingungenbewegt,wird,dadurch gekennzeichnet, daß der Anker außerdem einem vom erstgenannten Magnetfeld getrennten Magnetfeld einer so hohen Frequenz ausgesetzt ist, daß ihr der Anker nicht mehr zu folgen vermag. Claim: Device for recording sound vibrations by means of a vibrating element which is connected to an armature, which is moved by a magnetic field in the rhythm of the vibrations to be recorded, characterized in that the armature is also exposed to a magnetic field of such a high frequency which is separate from the first-mentioned magnetic field that the anchor can no longer follow her.
