Abstract:
A head-worn sound reproduction device is provided in the form of left and right earphones, which can either be clipped to each ear or mounted on other headgear. The earphones deliver high fidelity audio to a user's eardrums from near-ear range, in a lightweight form factor that is fully “non-blocking” (allows coupling in and natural hearing of ambient sound). Each earphone has a woofer component that produces bass frequencies, and a tweeter component that produces treble frequencies. The woofer outputs the bass frequencies from a position close to the ear canal, while the tweeter outputs treble frequencies from a position that is either close to the ear canal or further away. In certain embodiments, the tweeter is significantly further from the ear canal than the woofer, leading to a more expansive perceived “sound stage”, but still with a “pure” listening experience.

Claim (Index 6):
The sound reproduction system according to  claim 3  further comprising: input circuitry having:\n at least one input for receiving an audio signal, a left woofer output coupled to the left woofer component, a left tweeter output coupled to the left tweeter component, a right woofer output coupled to the right woofer component, a right tweeter output coupled to the right tweeter component; \n a left audio signal filter coupled to the at least one input and drivingly coupled to the left woofer component through the left woofer output, the left audio signal filter configured to apply a first gain to at least a first frequency band in a first frequency range extending from 20 Hz to 100 Hz and to apply a second gain to at least a second frequency band in a second frequency range that extends from 100 Hz up, wherein the first gain substantially exceeds the second gain; and \n a right audio signal filter coupled to the at least one input and drivingly coupled to the right woofer component through the right woofer output, the right audio signal filter configured to apply the first gain to at least the first frequency band and to apply the second gain to at least the second frequency band.
