Abstract
Various implementations include miniature loudspeaker drivers. In some aspects, an electro-acoustic driver includes: a cone having a surface area configured to radiate acoustic energy; a suspension coupled to the cone; and a support structure coupled to the suspension and having an outer linear dimension in a plane of the cone of approximately 6.0 millimeters (mm) or less, wherein the surface area of the cone is at least 49% of an overall cross-sectional area of the electro-acoustic driver in the plane of the cone.
