Abstract

A speaker includes a magnetic assembly having top and bottom air gaps that are spaced apart from one another along an axis. The speaker further includes a voice coil assembly having a bobbin with top and bottom voice coils. The bobbin is movable in upwards and downwards directions along the axis relative to the magnetic assembly with at least one of the voice coils being at least partially positioned respectively within at least one of the air gaps. The voice coils are spaced apart from one another along the axis with an outward offset such that in a mean axial position of the bobbin a larger portion of the top voice coil extends upwards above the top air gap than downwards below the top air gap and a larger portion of the bottom voice coil extends downwards below the bottom air gap than upwards above the bottom air gap.
