Zusammenfassung:	An audio speaker including a bobbin-less voice coil having epoxy-bound winding layers is disclosed. More particularly, a voice coil may include a first winding layer and a second winding layer coaxially arranged about a central axis. The winding layers may include respective wire turns coiled about the central axis in a longitudinal direction. The winding layers may be bound by an epoxy matrix. For example, the epoxy matrix may be disposed radially between the first winding layer and the second winding layer to bond first wire turns to second wire turns, and to bond the winding layers to a speaker diaphragm.
