39 s ability to carry magnetic flux furthermore the increased width of the connection portion 106 in this configuration does not increase the stiffness of the connection portion 106 since material stiffness is a function of the cube of the material thickness while only proportional to the width of the material the reduced stiffness of the connection portion 106 combined with its increased width allows maximum magnetic flux to pass through the connection portion 106 as well as the first and second leg portions 102 and 104 while allowing maximum deflection between the first and second leg portions 102 and 104 for maximum output sound pressure of a receiver incorporating the armature 100 fig1 shows an alternate embodiment in the form of an e shaped armature 130 the armature 130 includes a generally flat first leg portion 132 and a generally flat second leg portion 134 the second leg portion 134 has two legs 135 and 136 disposed generally transverse to the first leg portion 132 as shown in fig1 the first leg portion 132 is disposed between the two legs 135 and 136 as shown in fig1 and below the two legs 135 and 136 as shown in fig1 a connection portion 138 is in communication with the first and second leg portions 132 and 134 as shown in fig1 and 12 the connection portion 138 includes a portion 140 having a material thickness that is less than the other portions of the armature 130 the reduced material thickness is best shown in fig1 as shown in fig1 the connection portion 138 includes angled portions 142 integrally formed between the portion 140 and the.
