Patent abstract
A first earphone of an earphone system includes a first magnet assembly and a first voice coil. A second earphone of the earphone system includes a second magnet assembly and a second voice coil. The second magnet assembly has a magnetic polarity that is opposite to the first magnet assembly. The current direction in the second voice coil is reversed relative to the current direction in the first voice coil. The first earphone and the second earphone attract each other because of the opposite magnetic polarity between the first magnet assembly and the second magnet assembly.
