Abstract
Elongated scalar coils modify or enhance the audio quality and of a speaker system and its auditory effects on a user. A scalar coil has two spiral windings with opposite winding directions. Scalar coil is in series with an input of the speaker to change the sound signature and to reduce digital noise. Scalar coil is also in series with a laser emitter that produces a laser beam that travels through the scalar coil, which produce electromagnetic forces that improve perceived audio quality in a user.
