Abstract: An improved loudspeaker is disclosed. The speaker includes at least one permanent magnet, an electromagnet and a diaphragm. The diaphragm has an inner portion (active portion) and an outer portion (stabilizing portion) that are both typically ring-shaped. The interaction between the magnets causes the inner portion to move back and forth according to the electrical signal inputted. As the inner portion moves forward, the outer portion tends to move backward relative to the inner portion. The movement of the active portion tends to produce corresponding forces on the stabilizing portion that cause the stabilizing portion to move and create sound in a symbiotic fashion. In certain embodiments, the portions move relative to each other as sound is produced so that a relatively constant volume of air is displaced on either side of the diaphragm thus minimizing acoustic distortion.
