In a speaker device, each inner peripheral edge portion of a conductive damper and an ordinary damper is fixed to an area in the vicinity of a lower end of a cylindrical portion of a connecting member, and each outer peripheral edge portion of them is fixed to a support member. Therefore, the conductive damper and the ordinary damper are attached to an area within a constant winding width d1 of a voice coil. When the speaker device is driven, the voice coil bobbin vibrates in an axial direction of the speaker device. At this time, the voice coil bobbin sometimes rolls due to various factors. In the speaker device, since a fulcrum P11 of the rolling is within the winding width d1 of the voice coil, a distance r2 from the fulcrum P11 to an intersection P12 of a central axis of the speaker device and a plane surface F11 including a center point P13 in the winding width d1 of the voice coil becomes short, and the voice coil bobbin hardly rolls. Thus, at the time of the rolling, not only the contact of the voice coil and a pot type yoke, but also the contact of the voice coil bobbin and a plate can be prevented. Thereby, occurrence of an abnormal sound can be prevented.
