1. A loudspeaker, comprising:

  • a diaphragm wherein the diaphragm has a fixed portion and a movable portion and wherein the fixed portion is attached to the movable portion by a plurality of leaf springs disposed between the fixed portion and the movable portion of the diaphragm;

    a coil disposed over the diaphragm in the movable portion; and

    a magnet assembly operatively disposed relative to the coil, wherein upon flow of current through the coil, the movable portion of the diaphragm moves relative to the fixed portion,wherein the leaf spring has a first end portion, a second end portion and a body portion, the first end portion connected to the movable portion about an outer periphery of the movable portion and the second end portion connected to the fixed portion about an inner periphery of the fixed portion;

    wherein a gap between the body portion of the leaf spring and the fixed portion define a portion of a first slot and a gap between the body portion of the leaf spring and the movable portion define a portion of a second slot, wherein, the first slot extends to an adjacent leaf spring to define a gap between the body portion of the adjacent leaf spring and the movable portion, and wherein, the second slot extends to another adjacent leaf spring to define a gap between the body portion of the another adjacent leaf spring and the fixed portion, and wherein the first slot and the second slot is filled with a material to substantially maintain a pressure differential between a top portion of the diaphragm and the bottom portion of the diaphragm created by the movement of the movable portion of the diaphragm; and

    wherein the magnet assembly includes a top magnet assembly and a bottom magnet assembly and the diaphragm disposed between the top magnet assembly and the bottom magnet assembly.
