Description

BeschreibungDescription

Biegewellenwandler mit Masseausgleich zur Unterdrückung von Klirranteilen in der Flächenmembran.Bending wave transducer with mass compensation to suppress distortion in the surface membrane.

Die Erfindung betrifft einen Biegewellenwandler, bei dem eine oder mehrere Schwingspulen auf eine Flächenmembran aufgebracht werden. Diese Schwingspule oder Schwingspulen versetzen die Flächenmembran durch elektrische Ansteuerung in Schwingungen (Biegewellen). Die Oberfläche dieser Flächenmembran strahlt durch diese Schwingungen Schall ab.The invention relates to a bending wave transducer in which one or more voice coils are applied to a surface membrane. This voice coil or voice coils cause the surface membrane to vibrate (bending waves) by electrical control. The surface of this surface membrane emits sound through these vibrations.

Solche Biegewellenwandler werden aus den unterschiedlichsten Membranmaterialien hergestellt. Durch ihre unterschiedlichen Eigenschaften sind die verschiedenen Materialien mehr oder weniger geeignet, eine natürliche Wiedergabe von Tonquellen wie z.B. CD, DVD, Mikrofon usw. zu ermöglichen.Such bending wave transducers are made from a wide variety of membrane materials. Due to their different properties, the different materials are more or less suitable for enabling natural reproduction of sound sources such as CDs, DVDs, microphones, etc.

Die Erfindung soll einen Biegewellenwandler schaffen, dessen Membran aus einem Einscheiben-Glas oder Mehrscheiben-Verbundglas besteht. Es ist bekannt, dass Glas als Lautsprechermembran einen sehr hohen Klirrfaktor hat, und deshalb für die Anwendung als Biegewellenwandler ungeeignet ist.The invention is intended to create a bending wave transducer whose membrane consists of a single-pane glass or multi-pane laminated glass. It is known that glass as a loudspeaker membrane has a very high distortion factor and is therefore unsuitable for use as a bending wave transducer.

Um hier Abhilfe zu schaffen, versieht man deshalb die Randbereiche und/oder andere geeignete Bereiche der Glasscheibe mit Gewichten, die aus allen erdenklichen Materialien, hier vorzugsweise aus Glas, bestehen können und formschlüssig und/oder kraftschlüssig mit der Membran verbunden sind. Siehe Fig.1 (3)To remedy this, the edge areas and/or other suitable areas of the glass pane are provided with weights that can be made of any imaginable material, preferably glass, and are connected to the membrane in a form-fitting and/or force-fitting manner. See Fig.1 (3)
