FIELD: physics. ^ SUBSTANCE: flat loudspeaker has an oscillatory system (2) with an oscillating body (4) and at least one vibration exciter (6) connected to the oscillating body (4) and loaded with an acoustic signal. The vibration exciter (6) is connected to at least one flat element (8). There is at least correcting element (14, 16) on the flat element (8) for matching oscillatory behaviour of the oscillatory system (2). At least one flat element is connected through a flexible coupling element to the side of the vibration exciter turned away from the oscillating body. ^ EFFECT: easy correction of frequency characteristics. ^ 10 cl, 2 dwg |
