Abstract
A simple technique permits improving the distortion of a loudspeaker with a magnetic system. The magnetic system incorporates measures for operation thereof within the saturated region of the magnetic characteristic of the magnetic system. These measures comprise a division of the magnetic circuit into a section with magnetic saturation, and sections without magnetic saturation, which are adjacent to an air gap.
