ABSTRACT:
Headphones with a multichannel guiding mechanism having different channel speakers positioned within each of earphones and separate sound-guiding chambers for receiving the different channel speakers. In taking the acoustics into account, the separate sound chambers are installed within the earphones according to the sound effect of different channel speakers. An inner and an outer tube are installed within the first sound chamber. The inner tube defines a treble area in the middle of the front main speaker while the outer tube defines a bass area around the treble area whereby the first sound chamber has a tube-in-tube configuration. Accordingly, a clear positioning of the acoustic field is achieved by different installation position of the speakers within the earphones. In addition, the interference of sound waves is avoided and the reproduction of original sound is achieved.
