Acoustic radiation from a Distributed Mode Loudspeaker (DML) results from low amplitude bending waves. Compared with the motor system of a pistonic driver, the DML exciter is of subtly different design and equivalent circuit with a different relationship to the radiating diaphragm. In this paper, loudspeaker distortions are reviewed, the equivalent circuits modeled and compared with the DML case, and the results for comparative measurements are presented.
