An anti-diffraction plate for including in a planar magnetic transducer. The anti-diffraction plate includes anti-diffraction structures for positioning adjacent to magnets of the planar magnetic transducer. By introducing a shape over top surface of the magnets, the anti-diffraction structures cause the elimination of diffraction patterns as a main audio wavefront passes by the magnets from a diaphragm. A diffusion structure for diffusing reflected sound waves, the diffusion structures reducing or eliminating the power and capacity of the reflected sound waves to create interference patterns with oncoming sound waves.
