LOUDSPEAKER WITH IMPROVED VOICE COIL SUPPORT

A loudspeaker comprising a voice coil bobbin with a voice coil wound around its periphery is disposed in an annular gap formed between a columnar pole and a plate surrounding said pole. A plurality of terminals are mounted on the plate so that they are distributed on the circumference of a circle concentric with respect to the axis of said bobbin and mounted rotatably about their respective axes which are in parallel with the axis of said bobbin, with the terminals being coupled through suspension wires to the bobbin. The suspension wires may be of high resiliency, and have a layer of viscous resilient material surrounding the same. The voice coil bobbin of a loudspeaker may comprise a cylindrical body with a voice coil wound around its periphery, plural turns of a heat-resisting ribbon member impregnated with the thermosetting adhesives provided around the cylindrical body with the voice coil strip metal pieces inserted in between turns of the ribbon around the cylindrical body and aligned in the circumferential direction with a certain spacing left between respective ones so that both ends of each strip metal piece, project from the side edges of the ribbon, wherein projecting ends of the strip metal pieces are folded as to lie on the ribbon outer turn and these folded portions are heated to harden the thermosetting adhesives to fix the metal pieces to the ribbon.
