Abstract
An integrated armature and yoke for an acoustic receiver is disclosed. The armature includes a generally u-shaped member having a first portion arranged substantially parallel to a second deflecting portion. The yoke includes a central portion connected to the first portion, and first and second wall portions extending from opposite sides of the central portion toward the second deflecting portion. In a receiver, the second portion of the integrated armature and yoke is disposed through a receiver coil and extends into a space between permanent magnets, wherein an excitation signal applied to the coil causes the second deflecting portion of the armature to deflect between the magnets and to drive an acoustic sound generating diaphragm.
