PURPOSE:To surely assemble a speaker in a short period by projecting the light through a light guide consisting of an optical fiber and arbitrarily setting optimum angle, distance, etc., of irradiation to efficiently project the light. CONSTITUTION:A photosetting adhesive is stuck to a junction part (a) between a voice coil 5 and a cone 2, a junction part (b) between the voice coil 5 and a damper 6, a junction part (c) between the damper 6 and a frame 1, a junction part (d) between an edge 3 and the frame 1, a junction part (e) between the cone 2 and a dust cap 7, and a junction part (f) between the cone 2 and a lead wire 11, and the light is projected to this adhesive to harden it. In this case, the light is projected through the light guide consisting of the optical fiber. Thus, optimum angle, distance, etc., of irradiation are arbitrarily set, and the light is efficiently projected by local spot irradiation, and the speaker is surely assembled in a short period.
