A vibrator includes a magnetic circuit having a magnetic gap, a voice coil having a coil arranged in the magnetic gap and a bobbin around which the coil is wound on one end side, a flange member coupled to the other end side of the bobbin protruding from the magnetic circuit, and an elastic coupling member coupling the magnetic circuit and the flange member so that the magnetic circuit and the flange member can vibrate relative to each other. The elastic coupling member includes a first fixed portion, a second fixed portion, and an elastic deformation portion coupling the first fixed portion and the second fixed portion via elastically-deformable coupling portions. The elastic coupling member is configured such that the first fixed portion, the second fixed portion, and the elastic deformation portion are integrally formed, and substantially houses the magnetic circuit, the voice coil, and the flange member inside.
