Abstract: A sound converter includes a rectangular frame, a first suspension seated on an upper side of the frame to vibrate, a second suspension attached to a bottom surface of the first suspension and electrically connected to a voice coil to vibrate, a magnetic circuit including a center magnet, a plurality of sub-magnets spaced apart from the center magnet by a certain distance to define a magnetic gap, a plurality of top plates positioned above the center magnet and each sub-magnet, and a bottom plate positioned below the center magnet and each sub-magnet, and a third suspension connecting a lower end or a lower end lateral surface of the voice coil to the frame to vibrate. The voice coil is attached to a bottom surface of the second suspension. The third suspension is positioned through spaces defined by the sub-magnets being spaced apart from each other.
