Abstract: A loudspeaker damper, a manufacturing method thereof, and a loudspeaker, electronic equipment and device using the loudspeaker damper. The damper has flexibility. Therefore, even if a large input is applied and the damper oscillates with a large amplitude, a resin layer provided on the surface of the damper base material is not cracked due to partial interface peeling. Thus, the damper follows such a large amplitude and realizes high input-resistance. This loudspeaker damper material is obtained by impregnating a material with thermosetting resin including 2 to 20 wt % of flexibility imparting agent and heat-curing thereof.

Abstract: An ultra low frequency transducer or subwoofer for automotive speaker systems with a polygonal, concave diaphragm. The periphery preferably is sized to be substantially coextensive with the front of the speaker housing or cabinet. In this way, air displacement in the subwoofer is maximized for a given size of enclosure, and thus so is the loudness of the speaker. The transducer typically includes a frame or basket with a polygonal front for supporting the periphery of the diaphragm. The preferred diaphragm includes a convex surround with pleated corners. For increased durability, trusses are formed in the diaphragm.

Abstract: An acoustic passive radiator that controls "rocking mode" vibration. An acoustic passive radiator includes a diaphragm for radiating acoustic energy. The diaphragm has a perimeter portion and a central portion. The perimeter portion is thicker than the central portion. The passive radiator further includes a passive radiator suspension. The suspension includes a skin element encasing the diaphragm. The skin element comprises a surround for physically coupling the passive radiator to an acoustic enclosure, pneumatically sealing the diaphragm and the enclosure. The surround has a non-uniform width. The passive radiator a non-pneumatically sealing, non-surround, non-spider suspension element. The non-surround suspension element and the surround coact to control the motion of the diaphragm and to support the weight of the diaphragm.
