Abstract
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 ( ) and at least one driver ( ). As a general rule, the driver ( ) is arranged on an auxiliary frame at a distance from the acoustic panel ( ). Said embodiment makes it possible to use conventional drivers ( ) that can also be utilized in cone loudspeakers. A series of problem arise when the drivers ( ) are to be integrated on or into the acoustic panel ( ) itself. Said embodiment requires inter alia that the different components of the driver ( ) be directly mounted on the acoustic panel ( ). Hence, the invention aims at providing a driver for panel loudspeakers that can be connected with little complications to the acoustic panel ( ) as a pre-fabricated component. This is achieved by connecting the oscillation coil support ( ) in the air gap ( ) to the permanent magnet ( ) and/or to magnetic return path device using an elastic membrane ( ).
