  • Patent number: 8098874
    Abstract: A hanging type earphone with a hinge unit includes an earphone body, a hang member and a hinge unit. The earphone body has a connecting base defining a receiving space. The hinge unit received in the receiving space includes a positioning base, an axis cover and a pivotal axis having a mating portion whose cross-section is a polygon. The axis cover presses against the positioning base to form a pivotal space, one end of the pivotal axis is fixed in the hang member and the other end passes through the pivotal space, the mating portion mates with the side walls of the axis cover, thereby, the earphone body is positioned after rotating relatively to the hang member. Moreover, the pivot axis can be pulled out from the pivotal hole and then inserted into the pivotal space from the opposite direction, so the hanging type earphone can be hung on either ear of the user.
