Abstract

A magnetic gap-less loudspeaker of a high performance which has a good quality of a voice coil and provides easy wiring between tinsel wires and the voice coil. In the magnetic gap-less loudspeaker, two magnets (M1, M2) magnetized in the thickness direction are disposed with the same poles being faced each other and a voice coil (1) is disposed in a magnetic field generated by repulsion magnetic fluxes near at the outer circumferential areas of the magnets, wherein conductive areas (1C) made of copper foil or the like are attached to a skirt of said voice coil (1) extending from the lower end of said voice coil to the lower end of a coil bobbin, and input tinsel wires (2) are connected to said conductive areas.
