Headphones with ear hooks and open-back headphones

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 1, 2023, with application number 202311445248.4 and invention name “Headphone Earhook and Open Headphones”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application belongs to the field of earphone technology, and more specifically, relates to an earphone ear hook and an open earphone. Background Art

[0003] Bluetooth headsets are hands-free headsets that apply Bluetooth technology, allowing users to avoid the entanglement of annoying wires and make calls easily in various ways.

[0004] Currently, Bluetooth headsets are roughly divided into two categories: one is an in-ear headset in which the sound element is worn inside the user's ear canal when in use; the other is an open-ear headset in which the sound element is worn outside the user's ear canal to produce sound. Since the sound element of open-ear headsets is suspended outside the user's ear canal, open-ear headsets cannot be worn through the user's ear canal as an auxiliary. Therefore, open-ear headsets generally require an ear hook on the headset body for auxiliary wearing.

[0005] The ear hooks of current open-type Bluetooth headsets are generally designed to include a memory metal wire and a shell that wraps the memory metal wire. The shells of existing ear hooks are made of a relatively hard plastic material, which has a poor fit on the user's ears, resulting in poor wearing comfort for the user. Technical issues

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0043] Please refer to Figures 1 to 12, and the headphone ear hook provided in the embodiment of the present application will now be specifically described. The headphone ear hook includes an ear hook component 10, an headphone connection structure 50 and a power connection structure 80.

[0044] As shown in Figure 2, the ear hook assembly 10 includes a protective cover 20, a memory metal wire 30 and a wire 40. The protective cover 20 wraps the memory metal wire 30 and the wire 40. The protective cover 20 includes at least two flexible layers arranged from the inside to the outside, and the physical properties of each flexible layer are different. The earphone connection structure 50 and the power connection structure 80 are respectively connected to the two ends of the protective cover 20, and are used to connect the earphone body and the power supply respectively. As shown in Figure 6, one end of the wire 40 passes through the earphone connection structure 50 for electrically connecting to the earphone body, and the other end passes through the power connection structure 80 for electrically connecting to the power supply, so that the power supply and the earphone body can be electrically connected through the wire 40.

[0045] Compared with the prior art, the earphone ear hook of the present application has a protective cover 20 including at least two flexible layers arranged in sequence from the inside to the outside, such as two flexible layers, three flexible layers, four flexible layers, etc. The physical properties of the ear hook component 10 can be adjusted by changing the material, hardness, and thickness of each flexible layer to change the softness of the ear hook component 10, so that the ear hook component 10 can reach a softness that can fit well to the user's ear, which is conducive to improving the user's wearing comfort.

[0046] In one embodiment of the present application, the hardness of the flexible layers increases from the inside out. Since the outermost flexible layer often comes into contact with the user's skin and is susceptible to friction and wear, by increasing the hardness of the flexible layers from the inside out, the outermost flexible layer can be made harder than the other flexible layers, thereby maintaining the softness of the entire protective cover 20 while also being less susceptible to wear.

[0047] In one embodiment of the present application, the cross-sectional area at both ends of the ear hook assembly 10 is larger than the cross-sectional area in the middle portion.

[0048] Specifically, when the earphone ear hook of the present application is worn on the user's ear, the middle position of the ear hook component 10 is hung on the upper side of the user's ear where it is connected to the head. By designing the ear hook component 10 to be a structure that is thin in the middle and thick at both ends, the ear hook component 10 can be limited to the user's ear, and will not shake when worn on the user's ear, thereby improving the stability of wearing.

[0049] In other feasible embodiments, based on the cross-sectional area of ​​the ends of the earhook assembly 10 being larger than that of the middle, the hardness of each flexible layer can be configured to increase from the middle toward the ends. The middle of each flexible layer is the area that experiences the greatest deformation. If the hardness is too high, the deformation effect of the middle portion of the earhook assembly 10 will be affected. Therefore, by configuring the hardness of each flexible layer to increase from the middle toward the ends, the hardness of the middle portion of each flexible layer can be reduced, which helps to improve the flexibility of the middle portion of the earhook assembly 10. Combined with the cross-sectional area of ​​the ends of the earhook assembly 10 being larger than that of the middle portion, that is, the earhook assembly 10 having a thicker structure at the ends and a thinner structure in the middle, the middle portion of the earhook assembly 10 can further improve the ability of the middle portion of the earhook assembly 10 to follow the deformation of the memory wire 30, thereby allowing the middle portion of the earhook assembly 10 to better fit the user's ear.

[0050] In one embodiment of the present application, the innermost flexible layer is formed with a first receiving hole 221 for accommodating the memory metal wire 30 and a second receiving hole 222 for accommodating the conductive wire 40. All inner flexible layers are made of either silicone or silicone gel, both of which are highly flexible materials.

[0051] In one embodiment of the present application, the outermost flexible layer is made of one of silicone, TPU, and TPE. Silicone, thermoplastic polyurethane (TPU), and thermoplastic elastomer (TPE) are materials that not only have good flexibility but also good wear resistance. The outermost flexible layer is made of one of these materials. This ensures that the outermost flexible layer has good softness while also being less susceptible to wear, thereby increasing the service life of the ear hook assembly 10.

[0052] In one embodiment of the present application, a plurality of sweat-absorbing holes may be provided on the side of the outermost flexible layer that contacts the skin, and an elastic sweat-absorbing material may be provided within the sweat-absorbing holes. When hot weather causes the skin in contact with the earhook assembly 10 to sweat, the elastic sweat-absorbing material within the sweat-absorbing holes absorbs the sweat, thereby preventing discomfort caused by the sweat. Furthermore, the sweat-absorbing structure, which includes a plurality of sweat-absorbing holes provided on the first flexible layer 21 and an elastic sweat-absorbing material provided within the sweat-absorbing holes, does not affect the softness of the earhook assembly 10, allowing the earhook assembly 10 to maintain excellent softness. The elastic sweat-absorbing material may preferably be sponge or elastic sweat-absorbing fabric.

[0053] In one embodiment of the present application, there are two flexible layers, which are, from the outside to the inside, a first flexible layer 21 and a second flexible layer 22. Because in this embodiment, there are only two flexible layers, the first flexible layer 21 is the outermost flexible layer of the protective cover 20, and the second flexible layer 22 is the innermost flexible layer of the protective cover 20.

[0054] Optionally, the hardness of the first flexible layer 21 is greater than the hardness of , and the thickness of the first flexible layer 21 is greater than the thickness of the second flexible layer 22. The hardness of the first flexible layer 21 is preferably 30 to 80 shore A, for example, the hardness of the first flexible layer 21 may be 30 shore A, 40 shore A, 50 shore A, 60 shore A, 70 shore A, or 80 shore A. The thickness of the first flexible layer is preferably 0.2 mm to 0.6 mm, for example, the thickness of the first flexible layer 21 may be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, or 0.6 mm. The hardness of the second flexible layer 22 is preferably 0 to 10 shore A, for example, the hardness of the second flexible layer 22 may be 5 shore A or 10 shore A. The thickness of the second flexible layer 22 is preferably 0.8 mm to 2 mm, for example, the thickness of the second flexible layer 22 may be 0.8 mm, 1.5 mm, or 2 mm.

[0055] Specifically, after the materials of the first flexible layer 21 and the second flexible layer 22 are selected, their softness can be changed by changing the thickness and hardness of the first flexible layer 21 and the second flexible layer 22. After multiple tests, it was found that on the basis that the thickness of the second flexible layer 22 is greater than the thickness of the first flexible layer 21, when the hardness of the first flexible layer 21 is 30-80 shore A, the thickness is 0.2 mm-0.6 mm, and the hardness of the second flexible layer 22 is selected to be 0-10 shore A, the ear hook assembly 10 has the best softness and can well cooperate with the memory metal wire 30 to deform, so that the ear hook assembly 10 can fit the user's ear well.

[0056] In one embodiment of the present application, based on the fact that the number of flexible layers of the protective cover 20 is two, as shown in FIG3 , the protective cover 20 has a first cover end 201 and a second cover end 202 . As shown in FIG4 , one end of the earphone connection structure 50 is inserted into a first plug-in cavity 203 formed in the first cover end 201 , and one end of the power connection structure 80 is inserted into a second plug-in cavity 204 formed in the second cover end 202 . For example, the first flexible layer 21 has a first layer end 211 and a second layer end 212, the second flexible layer 22 has a third layer end 223 located within the first layer end 211 and a fourth layer end 224 located within the second layer end 212, the first layer end 211 and the second layer end 212 protrude out of the third layer end 223 and the fourth layer end 224 respectively along the extension direction of the second flexible layer 22, the first plug-in cavity 203 extends from the first layer end 211 to the third layer end 223, and the second plug-in cavity 204 extends from the second layer end 212 to the fourth layer end 224. By setting the first plug-in cavity 203 to extend from the first end 211 of the layer to the third end 223 of the layer, the earphone connecting structure 50 can be fixed to the first end 211 of the first flexible layer 21 and the third end 223 of the layer of the second flexible layer 22, so that the first end 211 of the first flexible layer 21 and the third end 223 of the layer of the second flexible layer 22 can move synchronously with the earphone connecting structure 50, and the resistance generated by the third end 223 of the layer of the second flexible layer 22 to the movement of the first end 211 of the layer of the first flexible layer 21 can be reduced. Similarly, by setting the second plug-in cavity 204 to extend from the second end 212 of the layer to the fourth end 224 of the layer, the power connection structure 80 can be fixed to the second end 212 of the layer of the first flexible layer 21 and the fourth end 224 of the layer of the second flexible layer 22, so that the second end 212 of the layer of the first flexible layer 21 and the fourth end 224 of the layer of the second flexible layer 22 can move synchronously with the power connection structure 80, and the resistance generated by the fourth end 224 of the layer of the second flexible layer 22 to the movement of the second end 212 of the layer of the first flexible layer 21 can be reduced.

[0057] In one embodiment of the present application, the conductive wire 40 is selected as an electric wire or a metal wire.

[0058] In one embodiment of the present application, as shown in FIG6 , the earphone connection structure 50 includes an intermediate connector 60 connected to the first end 201 of the sleeve and a rotating assembly 70 connected to the intermediate connector 60. The rotating assembly 70 is used to connect to the earphone body so that the earphone body can rotate relative to the intermediate connector 60. The power connection structure 80 is a curved columnar structure, and its curvature direction is the same as the curvature direction of the earhook assembly 10. In other feasible embodiments, the rotating assembly 70 can be removed, leaving the intermediate connector 60 connected to the first end 201 of the sleeve. The earphone body is directly connected via the intermediate connector 60, so that the earphone body can be rotated by driving the first end 201 of the sleeve of the protective sleeve 20 to twist.

[0059] Furthermore, in this embodiment, one end of the intermediate connector 60 is inserted into the first plug-in cavity 203, and the other end is connected to the rotating assembly 70. One end of the power connection structure 80 is inserted into the second plug-in cavity 204, and the other end is used to connect to the power supply. For example, the intermediate connector 60 includes a first plug-in block 61 inserted into the first plug-in cavity 203 and a second plug-in block 62 connected to the rotating assembly 70 outside the protective cover 20. A first fixing limit groove 611 is formed on one side of the first plug-in block 61. A first fixing limit structure is provided in the first plug-in cavity 203 corresponding to the first fixing limit groove 611. The first fixing limit structure is located in the first fixing limit groove 611. The second accommodating hole 222 passes through the first fixing limit structure. A first wire threading hole 621 for the wire 40 to pass through is provided on the second plug-in block 62 corresponding to the second accommodating hole 222. As shown in Figure 12, the power connection structure 80 includes a third plug-in block 81 inserted into the second plug-in cavity 204 and a fourth plug-in block 82 located outside the protective cover 20. A second retaining groove 811 is formed on one side of the third plug-in block 81. A second retaining structure is provided in the second plug-in cavity 204 corresponding to the second retaining groove 811. The second retaining structure is located in the second retaining groove 811. The second accommodating hole 222 passes through the second retaining structure. A second threading hole 821 is provided on the fourth plug-in block 82 corresponding to the second accommodating hole 222, through which the wire 40 passes. The coordinated arrangement of the first retaining structure and the first retaining groove 611 can increase the connection area between the headphone connection structure 50 and the protective cover 20, thereby increasing the connection force between the headphone connection structure 50 and the protective cover 20. Similarly, the coordinated arrangement of the second locking limiting structure and the second locking limiting groove 811 can increase the connection area between the power connection structure 80 and the protective cover 20 , thereby increasing the connection force between the power connection structure 80 and the protective cover 20 .

[0060] In this embodiment, referring to Figures 4 and 5 , the first retaining and limiting structure includes a first retaining and limiting protrusion 213 disposed within the first layer end 211 and located outside the third layer end 223, and a second retaining and limiting protrusion 225 disposed within the third layer end 223. The second receiving hole 222 extends through the first retaining and limiting protrusion 213 and the second retaining and limiting protrusion 225. The first retaining and limiting structure includes a third retaining and limiting protrusion 214 disposed within the second layer end 212 and located outside the fourth layer end 224, and a fourth retaining and limiting protrusion 226 disposed within the fourth layer end 224. The second receiving hole 222 extends through the first retaining and limiting protrusion 213 and the second retaining and limiting protrusion 225.

[0061] Optionally, the intermediate connector 60 and the power connection structure 80 are both made of silicone material, and the two ends of the memory wire 30 are respectively embedded in the first plug-in block 61 of the intermediate connector 60 and the third plug-in block 81 of the power connection structure 80. This arrangement allows the intermediate connector 60 and the power connection structure 80 to not only connect the rotating assembly 70 and the power source, but also, due to the elastic force of the silicone, the first plug-in block 61 of the intermediate connector 60 and the third plug-in block 81 of the power connection structure 80 can protect the two ends of the memory wire 30, thereby protecting the ends of the memory wire 30 from excessive bending and damage.

[0062] In one embodiment of the present application, as shown in Figure 8, the rotating assembly 70 includes a connecting tube 71 and a rotating connector 72. The rotating connector 72 is located outside the protective cover 20. One end of the connecting tube 71 is connected to the intermediate connector 60, and the other end can be rotatably connected to the rotating connector 72.

[0063] For example, the second plug-in block 62 of the intermediate connector 60 is inserted into the connecting tube 71, and the rotating connector 72 includes a connecting rod 722, a rotating plug-in protrusion 723 and a rotating plate 721. The connecting rod 722 and the rotating plug-in protrusion 723 are respectively located on opposite sides of the rotating plate 721, and the connecting rod 722 is located on the side of the rotating plate 721 away from the intermediate connector 60. The rotating plug-in protrusion 723 and the rotating plate 721 are both inserted into the connecting tube 71. The rotating plate 721 is rotatable relative to the connecting tube 71, and a rotation angle limiting structure is provided between the rotating plate 721 and the connecting tube 71 to limit the rotation angle range of the rotating connector 72. For example, as shown in Figures 9 to 11, the rotation angle limiting structure includes two symmetrical first rotation limiting protrusions 711 provided on the edge of the rotating plate 721, and two symmetrical second rotation limiting protrusions 7211 provided in the connecting tube 71. The first rotation limiting protrusions 711 and the second rotation limiting protrusions 7211 are provided in a one-to-one correspondence, and the two first rotation limiting protrusions 711 are located in a rotation angle limiting groove 712 formed between the two second rotation limiting protrusions 7211. When the rotating connector 72 and the connecting tube 71 rotate relative to each other, the first rotation limiting protrusion 711 slides in the rotation angle limiting groove 712. The range of movement of the first rotation limiting protrusion 711 in the rotation angle limiting groove 712 directly determines the angular range of relative rotation between the rotating connector 72 and the connecting tube 71.

[0064] Optionally, the edge of the rotating plate 721 has a first arc portion 7212 and a second arc portion 7213. The first arc portion 7212 and the second arc portion 7213 are arranged opposite each other and match the inner cavity of the connecting cylinder 71. The two first rotation-limiting protrusions 711 are respectively located at both ends of the first arc portion 7212. The cooperation between the first arc portion 7212 and the inner surface of the connecting cylinder 71 and the cooperation between the second arc portion 7213 and the inner surface of the connecting cylinder 71 enable the rotating connector 72 to perform stable rotational motion relative to the connecting cylinder 71, and prevent shaking along the radial direction of the connecting cylinder 71.

[0065] In this embodiment, the wire 40 passes through the rotating plug protrusion 723 and the rotating plate 721, enters the wire groove 7221 provided on the connecting rod 722, and then bends out of the wire groove 7221. For example, the rotating plug protrusion 723 is provided with a rotating member threading hole 7231 for the wire 40 to pass through. The rotating member threading hole 7231 passes through the rotating plate 721. The connecting rod 722 is provided with a wire groove 7221 on one end near the rotating plate 721, corresponding to the rotating member threading hole 7231. The wire groove 7221 extends along the axis of the connecting rod 722 and is connected to the rotating member threading hole 7231. The wire 40 passes through the rotating member threading hole 7231, enters the wire groove 7221, and then bends out of the wire groove 7221. The wire groove 7221 cooperates with the earphone body to secure the wire 40 in place. This arrangement ensures that after passing through the rotating plate 721, the wire 40 does not directly bypass the connecting rod 722, but instead enters the wire groove 7221 provided by the connecting rod 722, helping to reduce the overall size of the earphone earhook. The wire 40 is preferably bent at a 90° angle when exiting the wire groove 7221.

[0066] The present application also provides an open-type earphone, which includes the earphone earhook, earphone body and power supply in any of the above-mentioned embodiments. The earphone body and the power supply are respectively connected to the earphone connection structure 50 and the power connection structure 80 of the earphone earhook, and are respectively electrically connected to the two ends of the wire 40 of the earphone earhook. Therefore, the open-type earphone of the present application has at least all the beneficial effects of the earphone earhook of the above-mentioned embodiments, which will not be repeated here.

[0067] The open-type earphones provided in the present application adopt the earphone ear hook of the above-mentioned embodiment.
