Abstract

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 at 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.

Claims (7)

1. An armature for a receiver comprising:

a first armature leg portion having a thickness and a width;

a second armature leg portion having a thickness and a width, the second armature leg portion connected to the first armature leg portion; and

a connection portion in communication with the first and second armature leg portions, the connection portion joining with the first and second armature leg portions to form a substantially U shaped armature, the connection portion having a width greater than the width of the first and second armature leg portions individually, the connection portion reducing the stiffness of the armature and minimizing magnetic reluctance of the connection between the first and second armature leg portions.

2. The armature of claim 1 , wherein the first and second armature leg portions are separately formed.

3. The armature of claim 2 , wherein the connection portion is formed by a first segment integrally formed with the first armature leg portion and a second segment integrally formed with the second armature leg portion, the first and second segments attached to each other to form the armature.

4. The armature of claim 1 , wherein the first and second armature leg portions are spaced apart by the connection portion and generally parallel to each other.
