Solution

The correct option is C Ring Magnet
Loudspeaker requires magnets to have an influence in the opposite directions producing vibrations which in turn produces amplified sound. The speaker consists of a diaphragm, voice coil, copper cap, pole pieces, insulating materials and a magnet all in the shape of a ring.
