Abstract: A passive radiator structure includes an integrally formed diaphragm structure and a surround suspension. The diaphragm structure includes a diaphragm, a frame, and a web-like spider having a plurality of suspension arms integrally extended to between the diaphragm and the frame. The surround suspension has a radially inner gluing edge adhered to a radially inner location of the diaphragm structure around the diaphragm, and a radially outer gluing edge adhered to a radially outer location of the diaphragm structure around the frame. The surround suspension and the web-like spider of the diaphragm structure form two suspension elements for stably supporting the diaphragm, enabling minimized irregular shaking and reduced weight of the diaphragm, as well as reduced sound distortion, increased compliance and upgraded efficiency of the passive radiator structure.

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.
