Abstract

Die Erfindung betrifft eine Vorrichtung zur Anregung von Schwingungen in einer anzuregenden sternförmigen flächig ausgedehnten Übertragerstruktur. Insbesondere kann die Vorrichtung in einem Lautsprecher zur Wiedergabe von Audiosignalen eingesetzt werden. Die Vorrichtung weist mindestens zwei Anregungsmittel auf, welche jeweils mindestens einen Dauermagneten mit einem Ringspalt, mindestens eine ringförmige Tauchspule und mindestens einen Schwingteilträger aufweisen. Der Schwingteilträger ist an die Übertragerstruktur lösbar gekoppelt, und die Übertragerstruktur ist zwischen zwei Anregungsmitteln angeordnet.

The invention relates to a device for excitation of oscillations in a star-shaped surface extensively extended Übertragerstruktur. In particular, the device can be used in a loudspeaker for the reproduction of audio signals. The device has at least two excitation means, each having at least one permanent magnet with an annular gap, at least one annular plunger coil and at least one vibrating part carrier. The oscillatory subcarrier is releasably coupled to the transducer structure, and the transducer structure is disposed between two excitation means.
