Abstract
A loudspeaker allowing snap-together assembly and extensive use of plastic is provided. The magnet is substantially enclosed between a molded plastic basket and a threaded cap, and the magnet clamps the spider which centers the voice coil in place. The base of the cone of the loudspeaker is frictionally held between the basket and a clamping ring. The electrical connection between the voice coil and the input terminals includes conductive strips formed of conductive ink upon the spider. The conductive strips are soldered to the leads of the voice coil and are joined to the input terminals by pressure contacts of a terminal strap which is snapped in place in the plastic basket. A grille subassembly for mounting within the basket of the loudspeaker is provided to permit snap-together assembly of multiple loudspeaker systems. The electrical connections between the loudspeakers of the multiple loudspeaker system are made at final assembly by the terminal strap. A novel grille and support arrangement for the smaller speakers, as well as a novel positioning ring for the magnet assembly, are also disclosed.
