An armature for a receiver comprising a first and a second leg portion each having a thickness and a width and connected to each other, and a connection portion in communication with the first and second leg portions. The connection portion has a width greater than the width of the first and second leg portions individually. The connection portion reduces the stiffness of the armature and minimizes magnetic reluctance of the connection between the first and second leg portions. According to one aspect of the invention, the first and second leg portions are integrally formed with the connection portion and the connection portion includes a least a portion having a thickness less than the thickness of the first and second leg portions individually to reduce the stiffness of the armature. According to another aspect of the invention, the first and second leg portions are separately formed and attached to the connection portion in a way that reduces the stiffness of the armature.
