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