Abstract
A concept for modifying a loudspeaker signal to prevent diaphragm over-deflection, in which a diaphragm deflection signal is predicted block by block, in overlapping time blocks, on the basis of the loudspeaker signal, so as to obtain one diaphragm deflection signal block per time block, is made more efficient. In accordance with an embodiment, a temporal evaluation position is determined at which then an attenuation factor is calculated from the current diaphragm deflection signal block, with the application of which a modified current diaphragm deflection signal block is obtained, and then a modified loudspeaker signal is synthesized on the basis of the modified current diaphragm deflection signal block.
