Abstract:
Audio reproduction devices, including without limitation headphones, universal in-ear monitors and custom in-ear monitors, are improved by electrical design that targets a flat electrical impedance across a predetermined frequency range such as the typical audible range of 20 Hz-20 kHz. Headphones and earphones having a flat or linear electrical impedance characteristic will have more consistent audio performance when driven by different sources.

Claim (Index 17):
A method of designing a multi-driver personal audio reproduction device comprising:\n arranging an audio crossover and a plurality of audio transducers into a headphone that produces a desired frequency response when driven by an audio source; measuring the electrical impedance of the headphone over a predetermined frequency range; if the electrical impedance varies over a portion of the frequency range by more than a predetermined amount, adding a reactive shunt impedance to the headphone to correct the electrical impedance over the portion of the frequency range; and testing the audio frequency response of the headphone to confirm that the headphone with the reactive shunt impedance produces the desired frequency response when driven by the audio source.
