Abstract: A audio speaker includes two parallel magnetically permeable plates and a diaphragm movably supported parallel to and approximately equidistant from the plates by a surround. A magnet assembly is coupled to the two magnetically permeable plates and passes through an opening in the diaphragm. The magnet assembly includes two magnets that are coupled with two like poles adjacent the diaphragm. A voice coil is coupled around the opening in the diaphragm to move the diaphragm when an electrical current flows in the voice coil. A suspension ring may surround a portion of the magnet assembly with a first end sealed to the diaphragm and an opposing second end sealed to one of the two plates to separate a back volume from a front volume. Some embodiments include several magnetic assemblies passing through the diaphragm with a voice coil and a suspension ring for each magnet assembly.
