Open publisher page 0 citations

Abstract

The maximum motor strength of a loudspeaker is not attained with a voice-coil height equal to the airgap height. A slightly overhung coil-gap geometry can improve the efficiency of the loudspeaker motor. The loudspeaker designer is given a method to manage better the compromise between x MAX and the loudspeaker motor strength and the related parameters.
