Abstract
A dual-cone loudspeaker (100) includes a primary speaker cone (2) and an axially displaced secondary speaker cone (4) mounted to the back of a magnet structure (5). A rigid link (11) causes both cones to move in unison. The rigid link includes an open support structure (19) with equiangularly extending spokes that form a central hub (30). A ring (20) circumscribes the spokes and attaches to the first speaker cone. A rigid element (32) connects to the spokes and the secondary speaker cone so the primary and secondary speaker cones move in unison and improve the bass response for the loudspeaker. The rigid coupling device is also adapted to support a high frequency radiator (40) to extend the overall loudspeaker frequency response into higher frequencies.
