Abstract
A tool for arranging voice coil leadouts in a microspeaker comprises a mandrel having a top surface on which a bobbin and voice coil are positioned during formation of helicoidal leadout regions of the voice coil, a bobbin alignment feature for positioning at an inner diameter of the bobbin; a sleeve alignment element at a bottom region of the bobbin alignment feature, the sleeve alignment element having a first surface on which a sleeve of the microspeaker is positioned during the formation of the helicoidal leadout regions, and a gluing ring positioned about the mandrel and on a second surface of the sleeve alignment element for providing guide paths for distal ends of the leadout end regions extending in a direction from the mandrel to the sleeve alignment element.
