Abstract: A speaker assembly including a sound radiating surface suspended over a magnet assembly, a suspension member for suspending the sound radiating surface over the magnet assembly, a voice coil extending from a bottom side of the sound radiating surface, and a capacitive displacement sensor for sensing a movement of the sound radiating surface. The capacitive displacement sensor including a first conductive plate fixedly positioned over the sound radiating surface and a second conductive plate coupled to the sound radiating surface and vertically aligned with the first conductive plate, and wherein the second conductive plate is confined to an area that is entirely radially inward of the voice coil.
