Abstract

The correction circuit has at least one combination of a resistance value with at least one resistance (R1-R5) and a capacitive value with at least one capacitor (C1-C4) and/or an inductive value with at least one inductance (L5) in parallel with the sound transducer or loudspeaker (1), whereby each combination has a resistive, capacitive and/or inductive value connected in series.
