Various linkage assemblies are shown and described for connecting a first movable member to a second movable member of a transducer. The linkage assemblies provide for motion amplification or reduction and, when used for sound generating purposes such as hearing aids or speakers, three different schemes for compensating for amplification-induced distortion. One scheme for compensating for distortion while providing amplification is the use of a lower horizontal span segment in a closed-loop linkage assembly that is longer than a corresponding upper horizontal span segment or upper vertex. Thus, a horizontal span segment used to connect the loop to the first movable member of the armature is longer than a corresponding segment or vertex used to connect the loop to the second movable member. A second distortion compensating feature that provides amplification is found in the use of non-parallel legs used to connect the linkage loop to the housing. The legs extend from vertices that connect the upper and lower portions of the loop together and they extend inwardly toward each other in a non-parallel fashion as they extend from the vertices to the bottom panel of the housing. Finally, a third scheme involves the manipulation of the effective height of the upper and lower portions of the closed loop. By providing a lower portion of the closed loop with a greater effective height or length than the upper portion, amplification is provided with a distortion effect that can be used to counterbalance distortion effects generated by other features of the linkage assemblies. The converse of all three schemes can be used for motion or gain reduction as well.
