Abstract
The loudspeaker comprises a cone (2) and a beading (4) attached to the cone (2). The beading (4) is composed of a sprayable plastic layer which is soft in its solid state. The manufacture of the loudspeaker is facilitated by a process in which an open negative mold (16) is used in which the cone (2) is arranged and immobilized. Following this, the plastic is sprayed into the open negative mold (16) and the beading (4) is formed as a soft plastic layer which attaches itself to the cone (2). (FIG. 1)
