Abstract
Description
Die Erfindung betrifft eine Magnetantriebsvorrichtung für einen elektrodynamischen Schallwandler, nach dem Oberbegriff des Patentanspruchs 1, insbesondere für Dipol-Bandschallwandler. Ferner betrifft die Erfindung einen Schallwandler mit einer solchen Magnetantriebsvorrichtung.The invention relates to a magnetic drive device for an electrodynamic transducer, according to the preamble of
Solche Magnetantriebsvorrichtungen werden im Stand der Technik in Systemen, insbesondere in Dipol-Bandschallwandlern, welche nach dem Prinzip der Induktion elektrische Wechselspannung in Schall umwandeln, z. B. in Hi-Fi-Lautsprechern eingesetzt. Hierzu wird eine elektrisch leitfähige Membran (
Bei bekannten konstruierten Magnetantriebsvorrichtungen (
- – impulsgetreue Schallwiedergabe.
- – maximal zu erreichende Lautstärke.
- – Zeiteinheit in der die maximale Lautstärke erreicht wird.
- – Höhe der zugeführten elektrischen Leistung.
- – Mengengewicht der eingesetzten Magnetwerkstoffe.
- - impulsive sound reproduction.
- - maximum volume to be reached.
- - Time unit in which the maximum volume is reached.
- - amount of electrical power supplied.
- - Quantity weight of the magnetic materials used.
Zu erwähnen sei noch, dass durch die einseitige partielle Öffnung des Gehäuserahmens (
Die Aufgabe der Erfindung lag nun darin begründet, eine Magnetantriebsvorrichtung für einen Dipol-Bandschallwandler mit einem geometrisch und akustisch optimiertem Gehäuserahmen (
Der magnetische Feldrückfluss erfolgt nicht durch die akustische Hauptabstrahlachse (
Die mit der Erfindung erzielten Vorteile bestehen im Ergebnis darin, dass die eingangs erwähnten Nachteile vermieden werden und die oben genannten Eigenschaften positiv beeinflusst werden. Insbesondere die impulsgetreue Wiedergabe von Toninformationen und das räumliche Hörempfinden angehoben wird sowie Schallreflektionen innerhalb des Schallwandlers verringert werden. Ein weiterer wesentlicher Vorteil liegt in der gesteigerten Energie des Magnetfeldes im Luftspalt (
Ein Ausführungsbeispiel der erfindungsgemäßen Magnetantriebsvorrichtung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben. Die Zeichnung zeigt:An embodiment of the magnetic drive device according to the invention is shown in the drawing and will be described in more detail below. The drawing shows:
