An armature apparatus includes a first tine member, a second tine member, a center tine member, and a connecting portion. The connecting portion is coupled to the first tine member, the second tine member, and the connecting portion, and the connecting portion has a line of symmetry. The center tine member is attached to the connecting portion along the line of symmetry such that approximately one half the area of the connection portion is above the center tine member and approximately one half the area of the connection portion is below the center tine member. The attachment is effective to prevent a formation of a horizontal force in the center tine member along the third length when a vertical force is applied to the center tine member in the direction of third thickness. |

1. An armature apparatus for use in an acoustic device, the apparatus comprising:
a first tine member having a first length, a first width, and a first thickness, the first length being greater than the first width, the first width being greater than the first thickness, the first width and first length defining a first surface; a second tine member having a second length, a second width, and a second thickness, the second length being greater than the second width, the second width being greater than the second thickness, the second length and the second width defining a second surface; such that the first surface of the first tine member generally faces the second surface of the second tine member and such the first surface is disposed in generally parallel relation to the second surface; a center tine member having a third length, a third width, and a third thickness, the third length being greater than the third width, the third width being greater than the third thickness, the third length being generally parallel to the first length and the second length; a connecting portion being coupled to the first tine member, the second tine member, and the connecting portion, the connecting portion having a line of symmetry; such that the first tine member, the second tine member, the center tine member, and the connecting portion are formed together as a single piece without the use of welding or soldering; wherein the center tine is formed with the connecting portion along the line of symmetry such that approximately one half the area of the connection portion is above the center tine member and approximately one half the area of the connection portion is below the center tine member, the attachment being effective to prevent a formation of a horizontal force in the center tine member along the third length when a vertical force is applied to the center tine member in the direction of third thickness. |
