Abstract
A hearing device receiver includes a coil having a passage and an armature having a deflecting portion, a support portion, and a base portion interconnecting the deflecting portion and the support portion. The deflecting portion of the armature is disposed through the passage of the coil and between magnets of the receiver. A housing is disposed about the coil, the magnets and at least a portion of the armature. The support portion of the armature is fastened to the housing, and the base portion of the armature is unfastened to the housing. The deflecting portion of the armature is flexible relative to the base and the support portions thereof and free to move between the magnets in response to an excitation signal applied to the coil.
