Abstract
A transducer assembly configured to provide a substantially constant electromagnetic force factor when driving distally and proximally to a top surface. The transducer assembly can include two coil portions and two magnetic gaps separated by a region of greater reluctance. As one of the coil portions moves out of the magnetic gaps while driving in an axial direction, the other coil portion can move into the magnetic gaps to provide a substantially constant speaker force factor. The other coil portion can continue to move from its rest position, through its proximal magnetic gap, and into the distal magnetic gap to provide extended useful linear stroke by using both magnetic gaps in a sequential manner.
