Abstract
A planar magnetic loudspeaker may employ an airflow system having a magnet array separated from a diaphragm. The magnet array can have a plurality of airflow apertures that are arranged in a pattern and each continuously extending through a thickness of the magnet array to increase the signal-to-noise ratio of the planar magnetic loudspeaker.

A loudspeaker comprising a diaphragm separated from a first magnet array in a planar magnetic assembly, the magnet array comprising a bar magnet positioned in a non-magnetic tray having a plurality of airflow apertures arranged on opposite sides of the bar magnet.
An apparatus comprising a diaphragm separated from a first magnet array in a planar magnetic speaker assembly, the first magnet array having a plurality of airflow apertures separated in a pattern and each continuously extending through a thickness of the magnet array.
A method comprising:
- positioning a magnet array a separated distance from a diaphragm in a planar magnetic assembly, the magnet array having a plurality of airflow apertures arranged in a pattern;
- passing electrical current through the magnet array to induce movement of the diaphragm;
- and
- providing laminar airflow through the magnet array to mitigate entropy, pressure wave diffraction, and pressure wave reflection of sound waves passing from the diaphragm through the magnet array.
