Abstract: In one embodiment a loudspeaker includes a cylindrical, staged frame; an annular voice coil having coil wires mounted on a lower portion; an annular U type spaced around the voice coil and secured to a bottom of the frame, the U type including radial channels; a magnet on a center of the voice coil; a damper secured to the frame; a bridge including arms through the channels, the arms being secured between the voice coil and the damper; and a cone secured between a top of the frame and the voice coil above the coil wires. This construction can lower the center of gravity of the voice coil so that the loudspeaker can be made thin. Also, the voice coil is more stable when the loudspeaker is activating.
