Abstract: An acoustic device includes a resilient surround having a proportionately unequal distribution of half roll and inverted half roll segments. Half roll segments may be sized and located to provide additional clearance for internal components. Regions of transitional concavity may be sized and located to provide increased stiffness in one or more dimensions. Transitions between inversions of concavity may be smooth and free of localized inflexions.

Abstract: A moving magnet motor with a stator comprising first and second spaced coil-wound cores that each have a width, the cores separated by an elongated gap, and an elongated magnet located at least in part in the gap and lying generally along a motor depth axis that is in the gap and is generally uniformly offset from the cores, where the magnet has poles. The motor has a width axis that is perpendicular to the depth axis and is generally uniformly offset from the cores. The magnet has a width along the motor width axis and the cores each have a width along the motor width axis. Along the motor depth axis the ratio of the width of the magnet or a pole of the magnet to the width of a core varies.
