ABSTRACT:
A loudspeaker (10) with a magnet system (12) arranged in a space (32) surrounded by a conical diaphragm (14) has a core (20) of the magnet system (12) first connected to the loudspeaker basket (11) and only then is the pot (19) connected to the core 20. It is then possible to manufacture loudspeakers (10) with internally located magnet systems (12) on production lines which can also be used to manufacture loudspeakers with magnet systems (12) that are located on the outside of the basket (11). Because the pot (19) is only installed later in the core (20) a centering bushing (34) can be placed between the core (20) and the voice coil support (18), which leads to a considerable improvement in the production quality of such loudspeakers (10).
