A speaker device includes a damper allowing high linearity. The speaker device includes a vibration body including a damper and a voice coil bobbin (bobbin), and a magnetic circuit having a plate. The damper has a first member arranged opposite the plate, and a second member projecting on a side of the plate from the first member. The first member has a movable part elastically supporting the bobbin. The movable part is a flat plate, and behaves with respect to a bent part provided between the movable part and the second member with movement of the bobbin in an acoustic radiation direction and reverse. Therefore, when a constant force is given to the damper via the voice coil, a displacement of the damper with respect to a rest position can be substantially similar in such a case that the damper behaves in the acoustic radiation direction and the reverse.
