After bending one of the outer peripheries of the top plate in a direction away from the magnet, fold it back to a shape that covers it at a position away from the outer periphery of the magnet, and connect the outer periphery of the tip with the outer periphery of either the top plate or the pole yoke. A magnetically shielded speaker characterized in that the shortest distance is longer than the thickness of the magnet.
