Detailed Description

For a more clear and complete description of the technical solution of the present invention, the following description is made with reference to the accompanying drawings.

Referring to fig. 1, the present invention relates to an open-ear left-right universal earphone 100, which includes an ear hook 10 and an earphone body 11. The earhook and the earphone body form a non-revolving revolutionary pair 20, the earhook 10 is arranged so as not to fall off and be lost when worn by exchanging left and right ears, and of course, accessories of the general earphone, such as the sheath 12, the loudspeaker 50 and the wire 60, are also included. It should be noted that the utility model discloses a general earphone 100 about open ear also can not use wire rod 60, thereby sets up bluetooth receiving arrangement in earphone main part 11 and change into wireless earphone, sheath 12 is in order to prevent that wire rod 60 from splitting at the junction with earphone main part 11, has the mouth of sounding 31 and has back cavity leakage hole 30 at the upside design of earphone main part 11 in the downside design of earphone main part 11.

As shown in fig. 2 and 3, the revolute pair 20 includes a shaft core 20a, an elastic body 20b, a positioning cover 20c, and a fastener 20 e. The axle core 20a and the ear hook 10 are formed by a compression molding process, so that the axle core 20a and the ear hook 10 are integrated. The shaft core 20a has 1 hole 20a-1 for fastening and at least one limit boss 20a-2 at its center. The elastic body 20b, which may be a metal elastic sheet, an O-ring or a spring, functions to increase the damping of the rotating shaft so that it does not rotate automatically when in use. And a positioning cover 20c for assembling the shaft core 20a and the elastic body 20b, and a fastener 20e for passing through the central holes of the shaft core 20a, the elastic body 20b and the positioning cover 20c and assembling and fastening them into the rotating pair 20.
