Description

Einrichtung für akustische Schaufensterreklame Die Erfindung betrifft eine weitere Verbesserung der durch Patent 465 189 geschützten Einrichtung für Schaufenstersprechreklame, bei der die Schaufensterscheibe selbst als Sprechorgan verwendet wird.Device for acoustic shop window advertising The invention relates to a further improvement of the window advertising device protected by patent 465 189, in which the shop window itself is used as a speech organ.

Die Verbesserung besteht darin, daß der die Schaufensterscheibe erregende Anker des als Antriebsmittel dienenden Elektromagneten fest mit der Glasscheibe verbunden ist, so daß ihr Antrieb unmittelbar durch die zwischen Anker und Magnet bestehende magnetische Kopplung geschieht. Die Schaufensterscheibe wird bei dieser Antriebsweise ohne Vorspannung erregt. Sie kann daher die ihr aufgezwungenen Schwingungen nicht nur mit größerer Genauigkeit, sondern auch mit größerer Schwingungsweite ausführen. Die Folge hiervon ist die Erzielung einer klaren, von Nebengeräuschen freien Sprachwiedergabe sowie eine wesentliche Steigerung des elektroakustischen Wirkungsgrades.The improvement is that the one exciting the shop window Armature of the electromagnet serving as a drive means firmly attached to the glass pane is connected, so that their drive is directly through the between armature and magnet existing magnetic coupling happens. The shop window is on this one Excited drive mode without bias. It can therefore use the vibrations that are imposed on it Execute not only with greater accuracy, but also with greater oscillation amplitude. The consequence of this is the achievement of clear speech reproduction free of background noise as well as a significant increase in the electroacoustic efficiency.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung veranschaulicht.An exemplary embodiment of the invention is illustrated in the drawing.

Eine an der Schaufensterscheibe i (z. B. durch Aufkitten) befestigte Scheibe - 2 steht mittels der Verbindungsstange 3 mit dem Anker 4 eines aus dem Eisenjoch 5 und den Spulen 6 bestehenden Elektromagneten in Verbindung, welcher von einem schweren, z. B. aus Hartblei bestehenden Körper 7 getragen wird. Das große Gewicht des an einer Stange 8 befestigten Körpers 7 dient zur Schaffung eines großen Trägheitsmoments, durch das das Mitschwingen des Antriebsmagneten verhindert wird. Der Anker 4 wird von einer starken Blattfeder g getragen. Zur genauen Einstellung des Duftspaltes zwischen dem Anker und den Polen des Magneten sind die Regulierschrauben io und ii (Abb. i) vorgesehen.One attached to the shop window i (e.g. by cementing) Disk - 2 stands by means of the connecting rod 3 with the armature 4 one from the Eisenjoch 5 and the coils 6 existing electromagnet in connection, which from a heavy, e.g. B. made of hard lead body 7 is worn. The great Weight of the body 7 attached to a rod 8 is used to create a large one Moment of inertia that prevents the drive magnet from oscillating. The armature 4 is carried by a strong leaf spring g. For precise adjustment of the fragrance gap between the armature and the poles of the magnet are the regulating screws io and ii (Fig. i) provided.

Abb. 3 zeigt eine Schaltanordnung, bei der der Antriebsmagnet durch Gleichstrom vormagnetisiert wird. Diesem Gleichstrom wird der Sprechwechselstrom durch einen. Transformator übergelagert, dessen Primärwicklung Si bei a, b und c an die Ausgangsstufe eines Gegentaktverstärkers angeschlossen ist. Der Gleichstrom wird dem die Sekundärwicklung S2 enthaltenden Stromkreis des Antriebsmagneten bei e und d zu beiden Seiten des Überbrückungskondensators K zugeführt.Fig. 3 shows a circuit arrangement in which the drive magnet is premagnetized by direct current. This direct current is the speech alternating current through a. Superimposed transformer, the primary winding Si of which is connected to the output stage of a push-pull amplifier at a, b and c. The direct current is fed to the circuit of the drive magnet containing the secondary winding S2 at e and d on both sides of the bypass capacitor K.
