PURPOSE:To improve magnetic density by forming incorporatedly a positioning member made of a synthetic resin for performing the positioning of a yoke, a plate, a magnet or the like, and a voice coil and a damper so as to assemble efficiently a speaker. CONSTITUTION:The positioning member 12 is formed by a plastic such as polyestersulphone or the like so as to position the yoke, the plate and the magnet or the like. A speaker unit member 1 is pressed so as to fit the member 2 to the outer circumference of a center pole 12 and the magnet 13 is arranged by coating an adhesives to the face of the yoke 11. Then, the adhesives is coated to the face of the yoke 11 and the magnet 13 is arranged. Further, the adhesives is coated to the upper face of the magnet 13 and a top plate 14 with a frame 16 is arranged. In this case, the member 2 is fixed and adhered strongly by pressing a stepped part 14a into the outer circumference of the member 2. |
