[0002] Headphones generally include a headband assembly, ear forks connected to both ends of the headband assembly, and a sound unit connected to the ear forks. To facilitate storage and portability of headphones, some related art headphones have foldable ear forks. When the ear forks are in the folded position, they can reduce the space occupied by the headphones.

[0003] However, this practice usually causes the ear forks to be in a relatively loose state, and the ear forks are easy to switch between the folded position and the unfolded position. Sometimes, the user just needs to take off the earphones, but the ear forks may switch from the unfolded position to the folded position due to a slight shake of the earphones or under the action of gravity. When the user needs to wear the earphones again, the ear forks need to be manually moved from the folded position to the unfolded position, which is inconvenient to use and affects the user experience.

[0041] like Figure 1 As shown, the ear fork assembly provided by one embodiment of the present invention can be applied to earphones, wherein the earphones are head-mounted earphones, and the earphones can be configured with a call noise reduction function and / or an artificial intelligence noise reduction function; at the same time, it can also be configured with functions such as stereo surround.

[0042] Combine Figure 1 and Figure 2 The ear fork assembly includes a connecting arm 100, a rotating shaft mechanism 200 and an ear fork 300. The connecting arm 100 and the ear fork 300 are connected through the rotating shaft mechanism 200. The ear fork 300 can rotate relative to the connecting arm 100 by relying on the rotating shaft mechanism 200, thereby realizing the folding and unfolding functions.

[0043] like Figure 1 As shown, when the ear fork 300 is in the deployed position, the ear fork 300 rotates in the folding direction and can be rotated from the deployed position to the folded position; when the ear fork 300 is in the folded position, the ear fork 300 rotates in the deploying direction and can be rotated from the folded position to the deployed position.

[0044] It can be understood that the connecting arm 100 is used to connect the headband assembly of the headset, and the ear fork 300 is used to connect the sound unit. When the ear fork 300 is in the unfolded position, it is convenient for the user to wear and use the headset. When the ear fork 300 is in the folded position, it can reduce the space occupied by the headset and facilitate storage.

[0045] It should be noted that, in some embodiments, the connecting arm 100 can slide relative to the headband assembly. Thus, by sliding the connecting arm 100, the position of the sound unit can be adjusted to accommodate users with different head shapes; in other embodiments, the connecting arm 100 is fixedly connected to the headband assembly.

[0046] like Figure 2 As shown, further, the connecting arm 100 includes an outer cover body 110 and an inner cover body 120 connected to the outer cover body 110, wherein, when the user wears the earphones using the above-mentioned ear fork assembly, the inner cover body 120 is closer to the user's head than the outer cover body 110.

[0047] It should be noted that the outer cover 110 and the inner cover 120 are connected via a first fastener 130 , wherein the first fastener 130 may be a screw or a pin.

[0048] Combine Figure 1 、 Figure 3 and Figure 4 The rotating shaft mechanism 200 is rotatably connected to the connecting arm 100. Specifically, one end of the rotating shaft mechanism 200 is rotatably connected to the connecting arm 100, and the other end of the rotating shaft mechanism 200 can rotate toward or away from the connecting arm 100. The ear fork 300 is connected to the other end of the rotating shaft mechanism 200. In this way, the ear fork 300 can be folded or unfolded by relying on the rotating shaft mechanism 200.

[0049] Specifically, the hinge mechanism 200 is rotatably connected to an end of the connecting arm 100 away from the headband assembly, and the ear fork 300 is connected to the hinge mechanism 200 .

[0050] like Figures 5 to 8 As shown, further, the ear fork assembly also includes an elastic limiter 400 arranged on the connecting arm 100, wherein the rotating shaft mechanism 200 has a first locking portion 211 and a second locking portion 212, and the elastic limiter 400 is located on the rotation path of the first locking portion 211 and the second locking portion 212.

[0051] Specifically, when the ear fork 300 is in the unfolded position, the elastic limiter 400 is engaged with the first engaging portion 211, and the elastic limiter 400 is used to provide resistance to the ear fork 300 when the ear fork 300 rotates toward the folded position; when the ear fork 300 is in the folded position, the elastic limiter 400 is engaged with the second engaging portion 212, and the elastic limiter 400 is used to provide resistance to the ear fork 300 when the ear fork 300 rotates toward the unfolded position.

[0052] It is understood that when the ear fork 300 is in the unfolded position, the elastic limiting member 400 is engaged with the first locking portion 211. At this time, the elastic limiting member 400 exerts resistance on the ear fork 300 under the action of its own elastic force to prevent the ear fork 300 from turning to the folded position. In this way, the problem that the ear fork 300 is in a loose state when in the unfolded position and can be easily turned to the folded position can be improved. It is understood that when the user pulls the ear fork 300 so that the ear fork 300 can overcome the resistance applied to the ear fork 300 by the elastic limiting member 400, the ear fork 300 can be turned to the folded position. folded position; when the ear fork 300 is in the folded position, the elastic limiting member 400 is engaged with the second engaging portion 212. At this time, the elastic limiting member 400 applies resistance to the ear fork 300 under the action of its own elastic force, preventing the ear fork 300 from turning to the unfolded position. In this way, the problem that the ear fork 300 is in a loose state when in the folded position and can be easily turned to the unfolded position can be improved. It can be understood that when the user pulls the ear fork 300 so that the ear fork 300 can overcome the resistance applied to the ear fork 300 by the elastic limiting member 400, the ear fork 300 can be rotated to the unfolded position.

[0053] In the ear fork assembly of the present invention, the elastic limiter 400 is used to position the unfolded position and the folded position of the ear fork 300, thereby improving the problem of the ear fork 300 being loose when in the unfolded position and the problem of the ear fork 300 being loose when in the folded position. The problem of the ear fork 300 being easily switched between the folded position and the unfolded position can be reduced, thereby facilitating user use and improving the user experience.

[0054] Combine Figure 5 and Figure 6 In some embodiments, the elastic limit member 400 includes a connecting portion 410 connected to the connecting arm 100, and an elastic portion 420 connected to the connecting portion 410. The elastic portion 420 is located on the side of the rotating shaft mechanism 200, and the elastic portion 420 has a tendency to deflect toward the rotating shaft mechanism 200.

[0055] It is understandable that the connecting portion 410 is used to be fixedly connected to the connecting arm 100 , the elastic portion 420 is located on the side of the rotating shaft mechanism 200 , and the elastic portion 420 has a tendency to deflect toward the rotating shaft mechanism 200 by relying on its own elastic force.

[0056] Combine Figure 7 and Figure 8 Furthermore, the first latching portion 211 and the second latching portion 212 are both located on the side of the rotating shaft mechanism 200 , and the elastic portion 420 is located on the rotation path of the first latching portion 211 and the second latching portion 212 .

[0057] It can be understood that since the elastic part 420 has a tendency to deflect toward the hinge mechanism 200 by relying on its own elastic force, and the elastic part 420 is located on the rotation path of the first locking part 211 and the second locking part 212, as the hinge mechanism 200 rotates relative to the connecting arm 100, the elastic part 420 can be engaged with the first locking part 211 or the second locking part 212.

[0058] When the elastic portion 420 engages with the first engaging portion 211, the elastic portion 420 exerts a force on the rotating shaft mechanism 200 under its own elastic force, thereby preventing the rotating shaft mechanism 200 from rotating, thereby preventing the ear fork 300 from rotating to the folded position. This can alleviate the problem of the ear fork 300 being loose in the deployed position and easily rotating to the folded position. It can be understood that when the user pulls the ear fork 300 so that the rotating shaft mechanism 200 overcomes the resistance exerted by the elastic portion 420, the ear fork 300 can rotate to the folded position. When the elastic portion 420 engages with the second engaging portion 212, the elastic portion 420 exerts a force on the rotating shaft mechanism 200 under its own elastic force, thereby preventing the rotating shaft mechanism 200 from rotating, thereby preventing the ear fork 300 from rotating to the deployed position. In this way, the problem that the ear fork 300 is in a loose state when in the folded position and can be easily rotated to the deployed position can be improved. It can be understood that when the user pulls the ear fork 300 so that the rotating shaft mechanism 200 can overcome the resistance applied to the rotating shaft mechanism 200 by the elastic part 420, the ear fork 300 can be rotated to the deployed position.

[0059] Combine Figure 7 and Figure 8 Specifically, a snap-fitting protrusion 421 is provided on the side of the elastic portion 420 close to the rotating shaft mechanism 200; the first snap-fitting portion 211 and the second snap-fitting portion 212 are both concave structures. When the ear fork 300 is in the unfolded position, the snap-fitting protrusion 421 is snap-fitted to the first snap-fitting portion 211; when the ear fork 300 is in the folded position, the snap-fitting protrusion 421 is snap-fitted to the second snap-fitting portion 212.

[0060] Combine Figure 1 、 Figure 7 and Figure 8It should be noted that, when the ear fork 300 is rotated from the unfolded position to the folded position, the rotation direction of the rotating shaft mechanism 200 is defined as the first direction, and the second latching portion 212 and the first latching portion 211 are arranged in sequence along the first direction; the first latching portion 211 and the second latching portion 212 are concave structures, and a blocking portion 214 is provided between the first latching portion 211 and the second latching portion 212; when the engaging protrusion 421 is engaged with the first latching portion 211, the engaging protrusion 421 will provide resistance to the blocking portion 214, thereby preventing the rotating shaft mechanism 200 from rotating in the first direction; when the engaging protrusion 421 is engaged with the second latching portion 212, the engaging protrusion 421 will provide resistance to the blocking portion 214, thereby preventing the rotating shaft mechanism 200 from rotating in a second direction opposite to the first direction.

[0061] Combine Figure 5 and Figure 6 Furthermore, there are two elastic portions 420, each connected to the ends of the connecting portion 410 along the width direction of the connecting arm 100. A first latching portion 211 and a second latching portion 212 are provided on both sides of the rotating shaft mechanism 200 along the width direction of the connecting arm 100. At least a portion of the rotating shaft mechanism 200 is located between the two elastic portions 420, with one elastic portion 420 located in the rotation path of the first latching portion 211 and the second latching portion 212 on one side of the rotating shaft mechanism 200, and the other elastic portion 420 located in the rotation path of the first latching portion 211 and the second latching portion 212 on the other side of the rotating shaft mechanism 200. This makes the force applied to both sides of the rotating shaft mechanism 200 more uniform, improving the stability of the rotating shaft mechanism 200 during rotation.

[0062] Combine Figure 4 、 Figure 6 and Figure 7 In some embodiments, a rivet post 150 is provided on the inner wall of the connecting arm 100 , and a rivet hole 411 for the rivet post 150 to pass through is provided on the connecting portion 410 , and the rivet post 150 is riveted to the connecting portion 410 .

[0063] Specifically, the rivet column 150 is a columnar structure before riveting. After the connecting part 410 is installed, that is, the rivet column 150 passes through the rivet hole 411 of the connecting part 410, the rivet column 150 can be pressed into a "mushroom head" shape by using ultrasound, thereby achieving the fixation of the connecting part 410.

[0064] Of course, in some other embodiments, the connecting portion 410 may also be fixed to the connecting arm 100 by welding, bonding, or other methods.

[0065] Furthermore, a positioning groove 101 is provided on the inner wall of the connecting arm 100, and the connecting portion 410 is disposed in the positioning groove 101. When installing the elastic limiting member 400, the connecting portion 410 can be placed in the positioning groove 101 first, and the positioning groove 101 can be used to position the elastic limiting member 400. This can facilitate the subsequent fixing operation of the elastic limiting member 400 and improve the installation accuracy of the elastic limiting member 400.

[0066] like Figures 5 to 8 As shown, in some embodiments, the rotating shaft mechanism 200 includes a rotating shaft body 210 and a pin 220 passing through the rotating shaft body 210 . The pin 220 is rotatably connected to the connecting arm 100 , and the ear fork 300 is connected to the rotating shaft body 210 .

[0067] Specifically, the shaft body 210 is provided with a pin hole, and the pin shaft 220 is passed through the pin hole; the inner wall of the connecting arm 100 is also provided with two brackets 140 respectively located on both sides of the elastic limit member 400, and the two ends of the pin shaft 220 are rotatably connected to the two brackets 140. In this way, the shaft body 210 can be rotated relative to the connecting arm 100, so that the ear fork 300 can be rotated relative to the connecting arm 100 and thus folded or unfolded.

[0068] Combine Figure 2 and Figure 8 Furthermore, the shaft body 210 has a rotating connection portion 213, and the ear fork 300 is rotatably sleeved outside the rotating connection portion 213. Specifically, the ear fork 300 itself can also rotate relative to the shaft body 210, thereby achieving angle adjustment of the ear fork 300.

[0069] Furthermore, a damping ring 230 is provided on the outer cover of the rotating connection part 213, and the ear fork 300 can be rotatably sleeved on the outside of the rotating connection part 213 and abut against the damping ring 230. The damping ring 230 can provide a damping effect when the ear fork 300 rotates relative to the rotating connection part 213, thereby improving the user's hand feel. In addition, the damping ring 230 also has a silent effect, thereby improving the problem of excessive noise when the ear fork 300 rotates relative to the rotating connection part 213.

[0070] Specifically, the damping ring 230 is made of rubber material, the inner side of the damping ring 230 is interference fit with the rotating connection part 213 , and the outer side of the damping ring 230 is interference fit with the ear fork 300 .

[0071] It should be noted that the rotating connection part 213 is provided with an assembly groove 2131 , and the damping ring 230 is arranged in the assembly groove 2131 . The assembly groove 2131 is used to position the damping ring 230 to prevent the damping ring 230 from moving along the axial direction of the rotating connection part 213 .

[0072] like Figure 2As shown, further, the ear fork 300 includes an ear fork body 310 and an ear fork cover 320, the ear fork body 310 and the ear fork cover 320 cooperate to form an inner cavity, and the ear fork 300 is provided with an axial hole connected to the inner cavity, and the rotating connection part 213 is passed through the axial hole, so that the ear fork 300 is rotatably connected to the rotating connection part 213.

[0073] The ear fork body 310 and the ear fork cover 320 are fixed by a second fastener 330 , which may be a screw or a pin.

[0074] The utility model also provides an earphone, comprising the ear fork assembly of the above embodiment.

[0075] The earphones of the present invention are equipped with the above-mentioned ear fork assembly. In the ear fork assembly, when the ear fork 300 is in the unfolded position, the elastic limiting member 400 is engaged with the first latching portion 211. At this time, the elastic limiting member 400 exerts resistance on the ear fork 300 under the action of its own elastic force to prevent the ear fork 300 from turning to the folded position. In this way, the problem that the ear fork 300 is in a loose state when in the unfolded position and can be easily turned to the folded position can be improved. It can be understood that when the user pulls the ear fork 300 so that the ear fork 300 can overcome the resistance applied to the ear fork 300 by the elastic limiting member 400, the ear fork When the ear fork 300 is in the folded position, the elastic stopper 400 engages with the second stopper 212. At this time, the elastic stopper 400, under the action of its own elastic force, applies resistance to the ear fork 300, preventing the ear fork 300 from rotating to the deployed position. This can alleviate the problem of the ear fork 300 being loose in the folded position and easily rotating to the deployed position. It can be understood that when the user pulls the ear fork 300 so that the ear fork 300 overcomes the resistance applied by the elastic stopper 400, the ear fork 300 can rotate to the deployed position. Furthermore, in the ear fork assembly of the present invention, by using the elastic stopper 400 to position the ear fork 300 between the deployed and folded positions, the problem of the ear fork 300 being loose in the deployed position and the problem of the ear fork 300 being loose in the folded position can be alleviated, and the problem of the ear fork 300 easily switching between the folded and deployed positions can be reduced, thereby facilitating user use and improving the user experience.
