Claim:
A speaker comprising: a frame having a first perimeter opening and a bottom region rigidly spaced apart from the opening with said first perimeter defining a first plane; a magnet assembly rigidly affixed within and to the bottom region of the frame; and a voice coil driven movable assembly suspended from the opening of the frame and disposed to move along a longitudinal axis of said speaker with that axis being substantially perpendicular to said first plane, said voice coil driven movable assembly including: an outer flexible suspension having a first edge and a second edge with the first edge connected to said first perimeter of said frame and a first perimeter location of said voice coil driven moving assembly; a sound radiating surface having an outer edge and a central region with the outer edge affixed to the second edge of the outer flexible suspension; a bobbin having an upper edge, a lower edge and a central region with the central region of the bobbin sized, shaped and loosely suspended around a portion of the magnet assembly, with the upper edge of the bobbin affixed to central region of the sound radiating surface, and with a wire voice coil wound on said bobbin with a pair of wires extending away from the bobbin; and an inner flexible suspension includes an inner portion, an outer portion and at least one serpentine segment extending therebetween, with a separate end affixed to each of the inner and outer portions, with the inner portion affixed to the central region of the sound radiating surface in close proximity to the upper edge of the bobbin, with the outer portion affixed within and to the frame between the opening and the bottom thereof, with a pair of electrically conductive paths extending between the inner and outer portions integral with said at least one serpentine segment with one of said pair of wires of the voice coil connected to each of the pair of electrically conductive paths at the inner portion of the inner flexible suspension.
