| description | A tool for arranging voice coil leadouts in a microspeaker comprises an expanding collet constructed and arranged for positioning at an interior of a bobbin having an inner diameter, the expanding collet including a hole that extends through an interior in a longitudinal direction of the expanding collet; a center pin extending through the hole of the expanding collet, the expanding collet applying a force against the inner diameter of the bobbin in response to a position of the center pin in the hole of the expanding collet relative to the interior of the expanding collet; and a forming mandrel including a hole that extends through an interior in a longitudinal direction of the forming mandrel. The expanding collet extends through the hole in, and coaxial with, the forming mandrel. The expanding collet rotates the bobbin about the longitudinal direction of the expanding collet relative to the forming mandrel to form helical leadout regions of a voice coil about the bobbin. |
