イスコイルボビン。[Claims for Utility Model Registration] Inner wall portion 12 at the upper end of the voice coil bobbin 1
is formed into a thick cylinder, the inner diameter of which is sized to fit the outer diameter of the center pole 19, and an annular stopper 11 is formed on the inner upper end of the cylindrical portion 2, with which the upper end surface of the center pole 19 comes into contact when inserted. In addition, a small diameter cylinder 13 is formed on the upper surface of the stopper 11 to serve as a reference for insertion and adhesion of the center holes 32 and 34 of the damper 31 and the diaphragm 33, and the lower end of the voice coil bobbin 1 is , a voice coil bobbin for a dynamic type device that is structured so as to come into contact with the upper surface of the yoke 18 when inserted into the center pole 19. The head of the voice coil bobbin 21 is made thick and enlarged so that its outer periphery fits into the inner diameter of the center hole 16 of the plate 17, and the lower end of the voice coil bobbin 21 fits into the center hole of the plate 17. The voice coil bobbin of the dynamic type device is structured so that it comes into contact with the upper surface of the yoke 18 when inserted into the yoke 16.
