Abstract
The horn loudspeaker suffers from producing high distortions. Based on a physical model, an equivalent lumped-parameter circuit is determine d for a horn-loaded compression driver. From the nonlinear differentia l equation of this circuit, a compensation algorithm is implemented on a digital signal processor for reducing nonlinear distortion caused b y the behavior of air. Test results are presented.
