ABSTRACT:
A speaker device has a connecting member on which a groove capable of accumulating a constant amount of adhesive is formed. The groove is in the vicinity of a lower end of an outer peripheral wall of a cylindrical portion, and is formed on the outer peripheral wall of the cylindrical portion along a circumferential direction. A bottom surface of an inner peripheral edge portion of a conductive damper disposed on an upper side in plural dampers is fixed to the connecting member with adhesive applied to the groove. The adhesive is applied between the upper surface of the inner peripheral edge portion of the conductive damper and the outer peripheral wall of the cylindrical portion. Thus, the conductive damper, which is sandwiched by the adhesive applied to the groove and the adhesive applied to the upper surface of the conductive damper, is fixed to the connecting member.
