Abstract
A diaphragm for a balanced armature receiver and combinations thereof. The diaphragm includes a paddle having an area of concentrated mass located at or near a central portion of the paddle, the area of concentrated mass having an area density greater than an area density of other portions of the paddle, wherein the area of concentrated mass shifts a bending-mode frequency of the paddle to a lower frequency compared to a bending-mode frequency of the paddle in the absence of the area of concentrated mass.
