Abstract
A multi-channel headphone has a housing, multiple independent sound channels formed in the housing, and at least one speaker unit mounted inside the housing. The at least one speaker unit produces sound directly passing through one of the sound channels and refracted through the rest of sound channels. As the refracted sound is slower than the directly travelling sound, multiple layers of auditory feeling can be provided and a stereo sound effect can be generated for users to enjoy better auditory feeling.
