A coil surrounds the central limb of the armature and the two outside limbs which provide the fixed end of the armature are located on flat faces of a pair of wings formed by the pole piece itself and accurately positioned in the same plane with the vibrating tip of the armature at the exact center of the air gap between the magnets.
