Patent number: 6347149Abstract: The invention concerns the embodiment of drivers for panel loudspeakers. Panel loudspeakers working according to the principle of bending waves are already known in prior art. Said loudspeakers generally consist of an acoustic panel (11) and at least one driver (12). As a general rule, the driver (12) is arranged on an auxiliary frame at a distance from the acoustic panel (11). Said embodiment makes it possible to use conventional drivers (12) that can also be utilized in cone loudspeakers. A series of problem arise when the drivers (12) are to be integrated on or into the acoustic panel (11) itself. Said embodiment requires inter alia that the different components of the driver (12) be directly mounted on the acoustic panel (12). Hence, the invention aims at providing a driver for panel loudspeakers that can be connected with little complications to the acoustic panel (11) as a pre-fabricated component.Type: GrantFiled: January 4, 2001Date of Patent: February 12, 2002Assignee: Harman Audio Electronic Systems GmbHInventors: Wolfgang Bachmann, Gerhard Krump, Hans-Jürgen Regl
