Detailed ways

As shown in FIG. 1 , the present invention includes an earphone body 10 , an earhook 20 pivotally mounted on the earphone body 10 , and a two-way pivot mechanism 30 .

The ear hook 20 is pivotally mounted on the earphone body 10 so as to be pivotable in both directions.

The earphone body 10 is composed of a watch case 11 and a bottom case 12 facing each other, and there is suitable space for accommodating related components such as a circuit board 14 and an antenna inside the earphone body 10 . A shaft hole 13 is formed at one end of the bottom shell 12 for the two-way pivot mechanism 30 to pivot from inside to outside.

The two-way pivot mechanism 30 includes a base 31 and a circular shaft 32 formed on the base 31 .

As shown in FIG. 2 , the base 31 is disc-shaped, and a first notch 311 and a second notch 312 are respectively formed at appropriate positions around the base.

A pivot hole 33 is formed on the circular axis body 32 to penetrate radially for the pivoting of the earhook 20 . Several symmetrically arranged and elastically shrinkable arc protrusions 330 are formed on the wall of the pivot hole 33 . The first/second gaps 311/312 are used for positioning.

The body part of the ear hook 20 is arc-shaped for the user to hang on the ear. One end of the ear hook 20 forms a pivot portion 21 so as to be correspondingly pivoted in the pivot hole 33 on the circular shaft body 32 of the two-way pivot mechanism 30 . The pivot portion 21 is formed with several concave arc cut surfaces 210 on the equivalent radial surface, and the concave arc cut surfaces 210 respectively correspond to and cooperate with the arc convex portions 330 on the wall of the pivot hole 33 of the circular shaft rod 32 .

As shown in FIG. 2 , the earphone body 10 is provided with a baffle 40 on the inner side of the bottom case 12 , and one end of the baffle 40 is fixed on the inner side of the bottom case 12 , so that the baffle 40 is positioned below the two-way pivot mechanism 30 , and To support it; the other end of the baffle plate 40 is formed with two slots 41 parallel to the long sides, and between the two slots 41 is formed a stopper 42 that can be stretched up and down. The free end of the block 42 is formed with an upward protruding protrusion 420 , and the protrusion 420 respectively corresponds to the first/second notch 311 / 312 on the base 31 of the two-way pivot mechanism 30 .

A shaft cover 50 is fitted on the outer edge of the shaft hole 13 of the bottom case 12 . As shown in Fig. 3 and Fig. 4, a radial through hole 51 corresponding to the pivot hole 33 on the two-way pivot mechanism 30 is formed on the shaft cover 50, and the through hole 51 is for the pivot part 21 at one end of the ear hook 20 to pass through and pivot. It is arranged in the upper pivot hole 33 of the two-way pivot mechanism 30 .

In use, the bidirectional pivoting function of the earhook 20 is provided by the bidirectional pivoting mechanism 30 pivotally arranged on the earphone body 10 . As shown in FIG. 5 , the first direction is for the earhook 20 to pivot along the axial direction of the circular axis body 32 of the two-way pivot mechanism 30 ; The body 32 pivots in the axial direction of the radial pivot hole 33 . Wherein, when the earhook 20 pivots in the first direction, it can be used as a left and right ear switch, and when it pivots in the second direction, the tightness of the earphone body 10 against the ear can be adjusted, so that the user can wear the earphone set comfortably .

In addition to the two-way pivot angle adjustment function, the utility model also provides a positioning function: when the two-way pivot mechanism 30 pivots in the first direction with the earhook 20, when it pivots to a specific angle, the baffle 40 The stopper 42 on the top will enter the first notch 311 or the second notch 312 on the base 31 of the two-way pivot mechanism 30 with its protrusion 420 , so that the earhook 20 is positioned at the adjusted position in the first direction.

And because the earhook 20 and the two-way pivot mechanism 30 are both made of suitable elastic materials, such as plastic, when the pivot portion 21 of the earhook 20 is in the radial pivot hole 33 of the two-way pivot mechanism 30 in the second direction, When pivoting, its radial surface will be squeezed by the arc convex portion 330 on the wall of the pivot hole 33. After passing through, the arc convex portion 330 will be correspondingly locked on the concave arc section 210 on the pivot portion 21. In this situation Next, unless the pivot portion 21 is forced to rotate again, it will remain in this state, whereby the earhook 20 is positioned at the adjusted position in the second direction.

To sum up, the wireless earphone set of the present invention can use the two-way pivoting mechanism to adjust the angle of the earhook in two different directions, so as to produce the effects of switching between the left and right ears and adjusting the tightness of the fit. , after completing the angle adjustment and endowing it with a positioning function, so that the earhook can be positioned at the adjusted angle/position.
