ABSTRACT:
The invention relates to a planar loudspeaker comprising a light, thin soundboard (2) which may be energized to produce multiply-reflected bending waves, a surrounding frame (3) holding the soundboard (2) in an articulated, shear-resistant manner; at least one driver (6, 7, 9, 10) connected to the soundboard (2) to energize the soundboard (2); and at least one bridge (13, 16, 18, 20, 22, 25), rigidly connecting the at least one driver (6, 7, 9, 10) to the frame (3), wherein the bridge or at least one of the bridges (13, 16, 18, 20, 22, 25) is connected to the damping board (14).
