For example, the headphone assembly 100 may have any suitable form of ear hook, and / or the headphone assembly may have any suitable form of headphone part.

[0037] Figure 2A This is an exploded view of an earphone assembly 100 according to one or more embodiments of the present invention. Figure 2B yes Figure 2A A magnified view of a portion of the view. Figure 2C yes Figure 2A Another enlarged view of a portion of the image.

[0038] The hinge structure of the headphone assembly 100 includes a hinge seat 130 and a hinge frame 150 pivotally connected to the hinge seat 130. The hinge seat 130 has an axis x and is arranged coaxially with a first end 122a of the ear hook body 122. In one or more embodiments of the present invention, the hinge seat 130 is a one-piece metal part formed by a powder metallurgy process. In one or more other embodiments of the present invention, the hinge seat 130 may be a one-piece or one-piece metal part formed by any suitable process. The hinge seat 130 has a first seat portion 132 and a second seat portion 140 in the axial direction. The first seat portion 132 of the hinge portion 130 is configured to be fixedly connected to the first end 122a of the ear hook portion 120.

[0039] In one or more embodiments of the present invention, the hinge frame 150 is a one-piece metal part formed by powder metallurgy. In one or more further embodiments of the present invention, the hinge frame 150 may be a one-piece or one-piece metal part formed by any suitable process. The hinge frame 150 has a hinge frame base 152 and a hinge frame body 160. The hinge frame base 152 of the hinge frame 150 includes a hole 154 configured to be coaxial with the hinge seat 130 and rotatably fitted onto a second seat portion 140 of the hinge seat 130, thereby allowing the hinge frame 150 to pivot relative to the hinge seat 130. The hinge frame body 160 extends from the hinge frame base 152, and its extension direction is inclined relative to the axis of the hinge seat 130.

[0040] The hinge frame body 160 of the hinge frame 150 is fixedly connected to the earphone body 110. In the embodiment shown, the earphone body 110 has a recess 116 corresponding to the shape and size of the hinge frame body 160. The hinge frame body 160 of the hinge frame 150 can be received in the recess 116 of the earphone body 110, thereby being fixedly connected to the earphone body 110. In one or more embodiments according to the present invention, the hinge frame body 160 of the hinge frame 150 has a plurality of holes 162, and the earphone body 110 has a plurality of corresponding connecting posts 116a. The plurality of connecting posts 116a on the earphone body 110 respectively engage with the plurality of holes 162 on the hinge frame body 160, thereby fixing the hinge frame body 160 to the earphone body 110. Therefore, the earphone body 110 can pivot relative to the ear hook portion 120 via the hinge structure.

[0041] As shown in the figure, the hinge base 130 has an axial central opening 142. The cable 186 of the headphone assembly 100 is configured to pass through the central opening 142 of the hinge base 130. In one or more embodiments, the battery in the battery compartment 124 of the headphone assembly 100 is electrically connected to electronics within the headphone body 110 via the cable 186. Because the cable 186 passes through the hinge structure along the axial central opening 142 of the hinge base 130, pivoting of the headphone assembly 110 relative to the ear hook 120 does not affect the electrical connection between the battery in the battery compartment 124 and the electronics within the headphone body 110.

[0042] In the embodiment shown, the hinge frame 150 includes a cable hole 164 formed on its hinge frame body 160 for allowing a cable 186 to extend through. Correspondingly, a corresponding cable hole 116b is formed in the recess 116 of the earphone body 110 for allowing the cable 186 to extend through. In the embodiment shown, the hinge frame 150 also includes a pair of cable holding protrusions 166 formed on its hinge frame body 160 for holding the cable 186 therebetween. In the assembled state of the earphone assembly, the cable 186 extends from the ear hook portion 120 through the axial central opening 142 of the hinge seat 130, and is then held between the pair of cable holding protrusions 166 of the hinge frame body 160 of the hinge frame 150, and further extends through the cable hole 164 on the hinge frame body 160 and the cable hole 116b on the earphone body 110, and then enters the interior of the earphone body 110. Therefore, the hinge structure of the headphone assembly 100 is able to keep the cable 186 in place relative to the hinge structure when the headphone body 110 pivots relative to the ear hook 120.

[0043] In one or more embodiments of the present invention, the hinge structure may not include the center opening 142, the cable retaining protrusion 166, and the cable hole 164. In another one or more embodiments of the present invention, the hinge structure may include only one of the center opening 142, the cable retaining protrusion 166, and the cable hole 164. In yet another one or more embodiments of the present invention, the hinge structure may include only any two of the center opening 142, the cable retaining protrusion 166, and the cable hole 164. In these embodiments, the cable 186 can be held in place by any other suitable means.

[0044] In the embodiment shown, the hinge structure further includes a limiting structure for limiting the rotation angle of the hinge frame 150 relative to the hinge seat 130. In one or more embodiments, the hinge seat 130 includes a pair of limiting protrusions 136, and the hinge frame 150 includes a corresponding pair of limiting recesses 156. Figure 2A-2COnly one limiting recess 156 is visible (only one of the limiting recesses 156 is visible in the figure). The limiting protrusion 136 of the hinge seat 130 is received within a corresponding limiting recess 156 of the hinge frame 150. When the earphone body 110 pivots relative to the ear hook portion 120, the contact between the circumferential end walls of the limiting recess 156 of the hinge frame 150 and the limiting protrusion 136 of the hinge frame 150 (or the circumferential dimension of the limiting recess 156) limits the pivot angle of the hinge frame 150 relative to the hinge seat 130, and thus limits the pivot angle of the earphone body 110 relative to the ear hook portion 120. In one or more embodiments according to the present invention, the earphone assembly 100 may not include a limiting structure, or may have other limiting structures different from those shown in the figures.

[0045] In the embodiment shown, the hinge structure of the headphone assembly 100 further includes a friction ring or elastomer ring 170.

The friction ring 170 is configured to provide rotational damping between the hinge frame 150 and the hinge seat 130 of the hinge structure, i.e., between the headphone body 110 and the ear hook portion 120. The friction ring 170 provides a good tactile feel for the pivoting movement between the headphone body 110 and the ear hook 120, while the headphone body 110 can be properly held in any pivoting position relative to the ear hook 120. This allows for comfortable and stepless adjustment of the relative angular position of the headphone body 110 relative to the ear hook 120.

[0046] In the embodiment shown, the hinge structure of the headphone assembly 100 further includes a clip 176. A corresponding annular groove 144 is formed on the second seat portion 140 of the hinge seat 130. The clip 176 is adapted to engage with the annular groove 144 of the hinge seat 130, thereby preventing the hinge frame 130 from disengaging from the hinge seat 130. In the embodiment shown, the clip 176 is C-shaped. However, the present invention is not limited thereto; in one or more embodiments according to the present invention, the clip 176 may have any suitable structure and shape. In one or more embodiments according to the present invention, the headphone assembly 100 may include any other suitable limiting structure to prevent the hinge frame 130 from disengaging from the hinge seat 130.

[0050] In one or more embodiments of the present invention, the first seat portion 132 of the hinge base 130 of the hinge structure of the headphone assembly 100 can be fixedly connected to the ear hook portion 120 or the ear hook portion body 126 by any suitable means.

[0051] In one or more embodiments of the present invention, the hinge seat 130 includes a radial protrusion 138. The radial protrusion 138 of the hinge seat 130 can serve as the boundary between the first seat portion 132 and the second seat portion 140 of the hinge seat 130. That is, the portion of the hinge seat 130 axially below the radial protrusion 138 can be referred to as the first seat portion 132, and the portion axially above the radial protrusion 138 can be referred to as the second seat portion 140. The hinge frame base 152 of the hinge frame 150 is sleeved and hinged to the second seat portion 140 of the hinge seat 130 via a friction ring 170. At this time, the axially lower end of the hinge frame base 152 of the hinge frame 150 abuts against the radial protrusion 138 of the hinge seat 130, thereby ensuring the axial positioning of the hinge frame base 152 of the hinge frame 150 relative to the hinge seat 130. In one or more embodiments of the present invention, the limiting protrusion 136 of the hinge seat 130 is formed on the radial protrusion 138.

[0052] The hinge structure of the headphone assembly 100 also includes a clip 176. A corresponding annular groove 144 is formed on the second seat portion 140 of the hinge base 130. The clip 176 is configured to engage with the annular groove 144 of the hinge base 130 axially above the hinge frame 130, thereby preventing the hinge frame 130 from axially disengaging from the hinge base 130.

[0053] In one or more embodiments of the present invention, the hinge frame base 152 of the hinge frame 150 is coaxial with the hinge seat 130 and rotatably sleeved on the second seat portion 140 of the hinge seat 130.
