[0025] The following describes an open-ear headphone 10 according to a first embodiment of the present invention with reference to the accompanying drawings.

[0026] See also Figures 1 to 6 As shown, an embodiment of the present invention provides an open-type earphone 10, which includes an earphone unit 300, a connector 200 and a bracket 100. One end of the connector 200 is connected to the earphone unit 300, and the other end is connected to the bracket 100, and a first channel 2121 is defined inside the connector 200. The first channel 2121 is used for the bracket 100 to move so that the user can adjust the bracket 100 of the open-type earphone 10 by sliding the bracket 100, so that the open-type earphone 10 can be adapted to the size of the head. The bracket 100 has two connecting ends 110, and the two connecting ends 110 are respectively connected to the earphone unit 300, and the earphone unit 300 is separated from the earphone unit 300 and connected wirelessly. At least one connecting end 110 is connected to the connector 200, and the connecting end 110 is connected to the earphone unit 300 through the connector 200. The connecting end 110 is arranged in the first channel 2121, wherein the connecting end 110 can reciprocate along the first channel 2121, thereby changing the area of ​​the bracket 100 exposed outside the first channel 2121, that is, the bracket 100 can extend and retract in the first channel 2121 along the axial direction of the first channel 2121 relative to the connecting member 200 through the connecting end 110, thereby changing the length of the bracket 100 exposed to the outside to change the wearing size of the open earphone 10, so that the open earphone 10 can be adapted to the user's head.

[0027] Specifically, in one example, the number of the connection ends 110 of the bracket 100 is two, and the two connection ends 110 are separately arranged. The two connection ends 110 are connected to a connector 200, one end of the connector 200 is connected to the bracket 100, and the other end is connected to the earphone unit 300. Among them, the number of the earphone units 300 is also two, and the two earphone units 300 are respectively connected to different connectors 200, but connected to the same bracket 100, and the connector 200 is detachably connected to the bracket 100 and the earphone unit 300. At the same time, the two earphone units 300 are connected through wireless communication. When the open earphone 10 needs to be used, the wearing size of the open earphone 10 can be adjusted by controlling the bracket 100 to slide in the first channel 2121 relative to the connector 200 along the axial direction of the first channel 2121, so that the open earphone 10 can be adapted to the user's head for use.

[0028] In another embodiment, the number of the connection ends 110 of the bracket 100 is two, and the two connection ends 110 are arranged separately. Among them, only one connection end 110 is connected to the connector 200, the other connection end 110 is directly connected to the earphone unit 300, and the connection end 110 connected to the connector 200 is indirectly connected to the earphone unit 300 through the connector 200. The connection end 110 is arranged in the first channel 2121, and the connection end 110 can slide relative to the connector 200 along the axis direction of the first channel 2121. As a result, the bracket 100 of this embodiment can also adjust the wearing size of the open earphone 10, so that the open earphone 10 can be adapted to the user's head for use.

[0029] In conventional headphones or neck-hanging headphones, a wire is embedded in the bracket of the headphones, and the headphones connect two headphone units through the wire, so that the two headphone units can communicate with each other. In addition, the headphones also need to transmit power signals and audio data signals through wires. However, this setting makes the entire headset unusable when the bracket or one of the headphone units is damaged, and the headset needs to be repaired or replaced as a whole, which is complicated and time-consuming. In conventional wireless open-type headphones, the open-type headphones appear to include only two headphone units, and the two headphone units are wirelessly connected through internal parts, but the safety of such open-type headphones is relatively low. When engaging in outdoor activities or exercising, the headphone unit is easy to detach from the ear, causing it to fall off or be lost.

[0030] Compared to conventional headphones, the bracket 100 of the embodiment of the present invention does not need to be buried with wires connected to the earphone unit 300 to transmit power signals and audio data signals through the wires. The earphone unit 300 of the open earphone 10 communicates wirelessly, and the bracket 100, the connector 200 and the earphone unit 300 are detachably connected, so that when the open earphone 10 is damaged, the damaged parts can be disassembled and repaired separately, which will not affect the overall use of the open earphone 10. Compared to conventional wireless conductive headphones, the earphone units 300 of the embodiment of the present invention are connected through the bracket 100 to improve the safety of the earphone unit 300, so that the earphone unit 300 is not easy to fall when in use, and the safety is higher. Therefore, the open earphone 10 provided by the embodiment of the present invention can not only ensure the safety of the earphone in use, but also can disassemble and repair the damaged parts separately when the earphone is damaged, without affecting the overall use.

[0031] It should be noted that, as one example, the following embodiments will be described by taking the example that both connection ends 110 are connected to the connection member 200 .

[0032] In some embodiments, see Figure 2 , Fig.11 and Fig.12 As shown, the open earphone 10 further includes a first damping member 400, which is connected to the side of the connecting member 200 away from the earphone unit 300, and has a first through hole 410, which runs through both ends of the first damping member 400, and the connecting end 110 can be inserted into the first damping member 400 through the first through hole 410. Specifically, the first damping member 400 is disposed at the end of the connecting member 200, and the bracket 100 is movably disposed in the first through hole 410. When the bracket 100 slides relative to the connecting member 200 along the axial direction of the first channel 2121, the bracket 100 also slides relative to the first damping member 400 in the first through hole 410 to change the wearing size of the open earphone 10.

[0033] The first damping member 400 is made of a material with a high friction coefficient, such as a rubber material, a silicone material or a ceramic material, etc. When the first damping member 400 is made of a material with a high friction coefficient, a large friction force can be generated between the inner wall of the first through hole 410 and the bracket 100 when the bracket 100 and the first damping member 400 are connected and contacted with each other, so that the bracket 100 can slide relative to the connecting member 200 and the first damping member 400 only when it is pulled by an external force (such as: pulled by a human body), and in a normal state when the bracket 100 is not pulled by an external force, there is also friction between the inner wall of the first through hole 410 and the bracket 100, and the friction will prevent the bracket 100 from sliding relative to the connecting member 200. As a result, when the open-type earphone 10 is used, the bracket 100 and the connecting member 200 are always in the same connection position and will not change automatically, thereby ensuring that the open-type earphone 10 can maintain the same fit with the human head for a long time. At the same time, since the bracket 100 can slide relative to the connecting member 200, when the open earphone 10 needs to be stored, the bracket 100 can slide along the first channel 2121 so that most of the bracket 100 is accommodated in the first channel 2121, thereby reducing the overall volume of the open earphone 10 for easy storage, and the first damping member 400 can prevent the bracket 100 from sliding relative to the connecting member 200, so that the open earphone 10 always maintains the volume in the stored state, thereby improving the user experience.

[0034] In some embodiments, the first damping member 400 may not include the first through hole 410. That is, the first damping member 400 is a solid structure. In this embodiment, one end of the first damping member 400 is connected and fixed to the connecting end 110 of the bracket 100, and the first damping member 400 and the connecting end 110 are jointly arranged in the first channel 2121, and the first damping member 400 is interference-arranged in the first channel 2121 so that friction is generated between the first damping member 400 and the inner wall of the first channel 2121. When the bracket 100 is adjusted through the connecting end 110, since the first damping member 400 is connected and fixed to the connecting end 110 of the bracket 100, the connecting end 110 and the first damping member 400 will slide together in the first channel 2121 relative to the connecting member 200 along the axial direction of the first channel 2121. Since there is friction between the first damping member 400 and the first channel 2121, the first damping member 400 and the bracket 100 can only slide when they are pulled by an external force. In a normal state where the bracket 100 is not pulled by an external force, the friction between the first damping member 400 and the first channel 2121 will prevent the bracket 100 from sliding by itself. Therefore, the first through hole 410 is not provided on the first damping member 400. By making the first damping member 400 and the bracket 100 fixedly connected, the joint movement of the two can also prevent the bracket 100 from sliding by itself, thereby improving the connection strength and connection stability between the bracket 100 and the connecting member 200.

[0035] In some embodiments, see Figure 2 , Figure 4 and Figure 6 As shown, the connector 200 includes a housing 210 and a cover 220, the housing 210 and the cover 220 are connected, wherein the interior of the housing 210 defines a first channel 2121, the interior of the cover 220 defines a receiving chamber 221, the first channel 2121 is connected to one end of the housing 210 and communicates with the receiving chamber 221, and the first damping member 400 is disposed in the receiving chamber 221. Specifically, in one example, refer to Figure 4 As shown, the housing 210 has a first housing 211 and a second housing 212, the first housing 211 and the second housing 212 are detachably connected, and the first housing 211 and the second housing 212 jointly define a first channel 2121. In this embodiment, the first housing 211 and the second housing 212 are connected by screws. In other embodiments, the first housing 211 and the second housing 212 can also be connected by a buckle, or a magnetic connection, or a slide connection.

[0036] Further, the housing 210 has a first end 201 and a second end 202, the first end 201 and the second end 202 are arranged opposite to each other, the cover 220 is detachably connected to the first end 201 of the housing 210, and the first shell 211 and the second shell 212 are provided with external threads. When the first shell 211 and the second shell 212 are assembled to form the housing 210, the cover 220 is connected and fixed to the housing 210 through a threaded connection. Further, the first channel 2121 conducts through the first end 201 of the housing 210 so that the first channel 2121 and the accommodating chamber 221 are connected, so that the connecting end 110 of the bracket 100 can pass through the accommodating chamber 221 and enter the first channel 2121. The first damping member 400 is interference-fitted in the accommodating chamber 221, and the outer wall of the first damping member 400 is fitted with the inner wall of the accommodating chamber 221. Since the first damping member 400 is made of a material with a high friction coefficient, the first damping member 400 will generate friction with the inner wall of the accommodating chamber 221. At the same time, since the volume of the accommodating chamber 221 is adapted to the volume of the first damping member 400, the accommodating chamber 221 will also limit the first damping member 400, thereby preventing the first damping member 400 from sliding relative to the cover body 220 along the axial direction of the accommodating chamber 221. At the same time, since the cover body 220 is connected to the first end 201 of the housing 210, when the first damping member 400 is arranged in the accommodating chamber 221, the first end 201 of the housing 210 will abut against the first damping member 400, thereby further fixing the first damping member 400 in the accommodating chamber 221.

[0037] In other embodiments, the connecting member 200 does not include the cover 220, and the first damping member 400 is disposed in the first channel 2121. Specifically, the first damping member 400 is interference-fittedly disposed in the first channel 2121, and since the first damping member 400 is made of a material with a high friction coefficient, friction is generated between the first damping member 400 and the inner wall of the first channel 2121, thereby preventing the first damping member 400 from sliding relative to the connecting member 200 in the first channel 2121 along the axial direction of the first channel 2121. In this embodiment, the first damping member 400 is movably connected to the inner wall of the first channel 2121. Since the first damping member 400 needs to be connected to the bracket 100, in this embodiment, the first damping member 400 is fixedly connected to the bracket 100. Therefore, when the bracket 100 is telescopically adjusted, the first damping member 400 will also move with the bracket 100. The first damping member 400 is made of a material with a high friction coefficient so as to generate friction between the first damping member 400 and the inner wall of the first channel 2121 to prevent the first damping member 400 and the bracket 100 from sliding without external force. Therefore, the first damping member 400 can operate normally without the cover 220 and the first damping member 400 is arranged in the first channel 2121.

[0038] In another embodiment, the connecting member 200 does not include the cover 220, and the first damping member 400 is disposed in the first channel 2121. However, the first damping member 400 is fixedly connected to the first channel 2121, wherein the first damping member 400 has a first through hole 410. When the bracket 100 is inserted into the first through hole 410, friction will be generated between the bracket 100 and the inner wall of the first through hole 410. When the bracket 100 is telescopically adjusted, the bracket 100 will slide relative to the first damping member 400 and the connecting member 200 in the first channel 2121 and the first through hole 410 along the axis direction of the first channel 2121. At this time, the first damping member 400 will not move with the bracket 100. In this embodiment, the first damping member 400 is made of a material with a high friction coefficient in order to generate friction between the first damping member 400 and the bracket 100 to prevent the bracket 100 from sliding by itself without the action of external force.

[0039] In some embodiments, see Figure 6 , Figure 7 and Fig.13 As shown, the connection end 110 includes a limiting portion 111, which is formed by the outer wall of the connection end 110 protruding along the axis direction perpendicular to the first channel 2121, and the inner wall of the first channel 2121 is recessed along the axis direction perpendicular to the first channel 2121 to form a limiting groove 250, and the limiting portion 111 is accommodated in the limiting groove 250, and the limiting portion 111 is configured to limit the connection end 110 from rotating relative to the connection member 200. Specifically, the limiting portion 111 is formed by the outer wall of the connection end 110 protruding, and the direction in which the outer wall of the connection end 110 protrudes to form the limiting portion 111 is perpendicular to the sliding direction of the connection end 110. Similarly, the direction in which the inner wall of the first channel 2121 is recessed to form the limiting groove 250 is also perpendicular to the sliding direction of the connection end 110. The position and number of the limiting groove 250 and the limiting portion 111 are the same, so that after the connection end 110 is set in the first channel 2121, the limiting portion 111 can also be set in the limiting groove 250. When the connection end 110 slides in the first channel 2121, the limiting portion 111 will also slide with the connection end 110, but the limiting portion 111 slides in the limiting groove 250. In this embodiment, the limiting groove 250 is not connected to the first end 201 of the housing 210. Therefore, when the limiting portion 111 slides to one end distance in the limiting groove 250, the side wall of the limiting groove 250 along the axial direction will hinder the limiting portion 111 from continuing to slide, thereby preventing the limiting portion 111 from separating from the limiting groove 250.

[0040] Further, the limiting groove 250 has two side walls, and the limiting portion 111 is between the two side walls of the limiting groove 250. The limiting portion 111 and the limiting groove 250 are clearance-matched, that is, when the limiting portion 111 is accommodated in the limiting groove 250, there is a clearance between the limiting portion 111 and the two side walls of the limiting groove 250, so that the limiting portion 111 can move relative to the limiting groove 250, and avoids the friction between the limiting portion 111 and the limiting groove 250 after the limiting portion 111 and the limiting groove 250 are connected to cause wear on the two side walls of the limiting groove 250. Further, since the two side walls of the limiting groove 250 are located on both sides of the limiting portion 111, when the limiting portion 111 has a tendency to rotate relative to the connecting member 200 around the axis of the first channel 2121, the two side walls of the limiting groove 250 will abut against the limiting portion 111, thereby limiting the rotation of the limiting portion 111. Since the bracket 100 has two connection ends 110, if the limiting portion 111 rotates relative to the connecting member 200, the limiting portion 111 will also drive the connection ends 110 of the bracket 100 to rotate. When the bracket 100 rotates, torsional stress is generated on the bracket 100, so the limiting portion 111 is prevented from rotating relative to the connecting member 200 around the axis of the second channel 230, which can prevent the bracket 100 from being damaged or broken due to the superposition of torsional stress during the rotation process.

[0041] In some embodiments, see Figures 4 to 6 As shown, the second channel 230 is provided on one side of the connector 200 connected to the earphone unit 300, wherein the second channel 230 is provided at the second end 202 of the housing 210, and the second channel 230 is used to connect the earphone unit 300. Specifically, the first housing 211 and the second housing 212 cooperate with each other to define the second channel 230 at the second end 202 of the housing 210, and the first channel 2121 is separated from the second channel 230. The bracket 100 can slide in the first channel 2121 to change the wearing size of the open earphone 10, so that the open earphone 10 can be adapted to the user's head. The earphone unit 300 can move in the second channel 230 to change the fitting position of the earphone unit 300 and the user's ear, thereby improving the use effect. Therefore, by separating the first channel 2121 and the second channel 230, after the first end 201 and the second end 202 of the connecting member 200 are respectively connected to the bracket 100 and the earphone unit 300, the user can adjust the bracket 100 and the earphone unit 300 separately, so that the bracket 100 and the earphone unit 300 do not affect each other during the adjustment process.

[0042] Further, see Fig. 9 and Fig.10As shown, the earphone unit 300 is provided with a connecting portion 310, which is connected to the connecting member 200 and is rotatably arranged in the second channel 230. Specifically, the earphone unit 300 is provided with a connecting portion 310 on the side facing the connecting member 200. When the connecting member 200 and the earphone unit 300 are connected and assembled, the connecting portion 310 will be accommodated in the second channel 230, and the connecting portion 310 can rotate in the second channel 230 relative to the connecting member 200 around the axis direction of the second channel 230, thereby driving the earphone unit 300 to rotate relative to the connecting member 200 as a whole, thereby changing the fitting angle and fitting area between the earphone unit 300 and the ear. It should be noted that the first channel 2121 and the second channel 230 are arranged in parallel and spaced apart, and the axis of the first channel 2121 and the axis of the second channel 230 are also parallel to each other, and the axis of the first channel 2121 and the axis of the second channel 230 are parallel to the axis of the housing 210.

[0043] In some embodiments, see Figure 4 and Figure 6 As shown, the second channel 230 conducts the connection member 200 and is connected to the side of the connection part 310 to form a channel opening 231, that is, the second channel 230 conducts the second end 202 of the connection member 200 to form a channel opening 231, and the channel opening 231 is connected to the outside, so that part of the structure of the earphone unit 300 can pass through the channel opening 231 and connect to the second channel 230. It should be noted that, and in this embodiment, the channel opening 231 is a solid structure with thickness and length. The channel opening 231 is formed by the inner diameter formed with the axis of the second channel 230 as the center, and the length formed along the axis direction of the second channel 230. Among them, the inner diameter of the channel opening 231 is smaller than the inner diameter of the second channel 230, and when the connection part 310 is connected to the connection member 200, the connection part 310 will be rotated and set in the channel opening 231. Since the channel opening 231 is formed by the second channel 230 conducting the second end 202 of the shell 210, the channel opening 231 is also a part of the second channel 230.

[0044] Further, see Fig.10 , Fig.12 and Fig.14As shown, the earphone unit 300 further includes an abutting portion 320, which is connected to one end of the connecting portion 310 facing the second channel 230, and the connecting portion 310 is rotatably disposed at the channel opening 231, and the abutting portion 320 is disposed in the second channel 230. Specifically, in one example, the abutting portion 320 is rotatably disposed in the second channel 230, and in this embodiment, the abutting portion 320 is a cylindrical structure, and the diameter of the abutting portion 320 is greater than the inner diameter of the channel opening 231. Therefore, when the abutting portion 320 is accommodated in the second channel 230, the abutting portion 320 is restricted in the second channel 230 through the cooperation of the first shell 211 and the second shell 212, and because the diameter of the abutting portion 320 is greater than the inner diameter of the channel opening 231, the abutting portion 320 cannot be separated from the connecting member 200, thereby achieving the connection and fixation of the connecting member 200 and the earphone unit 300. When the abutting portion 320 slides toward the channel opening 231 along the axis of the second channel 230, the abutting portion 320 abuts against the channel opening 231, thereby limiting the sliding of the abutting portion 320 through the channel opening 231. At the same time, the channel opening 231 and the connecting portion 310 are connected with a gap. When the connecting portion 310 is connected to the channel opening 231 and the first shell 211 and the second shell 212 are connected, there is a gap between the connecting portion 310 and the inner wall of the channel opening 231, so that the connecting portion 310 can rotate relative to the connecting member 200 around the axis of the second channel 230 in the channel opening 231 to change the fitting angle and fitting area between the earphone unit 300 and the human ear.

[0045] Further, the connecting portion 310 is a structure having a length along the axial direction of the second channel 230, and the length of the connecting portion 310 along the axial direction of the second channel 230 is greater than the length of the channel opening 231. Since the connecting portion 310 is connected to the abutting portion 320, making the length of the connecting portion 310 greater than the length of the channel opening 231 can allow a gap to exist between the channel opening 231 and the abutting portion 320 along the axial direction of the second channel 230 after the connecting portion 310 is connected to the channel opening 231, that is, after the earphone unit 300 and the connecting member 200 are connected, the abutting portion 320 can be displaced relative to the connecting member 200 along the axial direction of the second channel 230, thereby preventing the abutting portion 320 from directly abutting against the inner wall of the channel opening 231 along the axial direction of the second channel 230 after the connecting portion 310 is connected to the channel opening 231. When the channel opening 231 contacts the abutting portion 320, frictional force is generated on the contact surface between the channel opening 231 and the abutting portion 320. Since the earphone unit 300 needs to rotate relative to the connecting member 200 through the connecting portion 310, there is a gap between the channel opening 231 and the abutting portion 320 along the axial direction of the second channel 230, and there is no friction between the two. This can avoid the friction between the abutting portion 320 and the channel opening 231 rubbing against the inner wall of the channel opening 231 when the connecting portion 310 rotates relative to the connecting member 200, thereby causing wear on the inner wall of the channel opening 231.

[0046] In some embodiments, Figure 8 , Figures 10 to 15 As shown, the side wall of the connecting portion 310 is provided with an extension portion 330 protruding along the direction perpendicular to the axis of the second channel 230, and the connecting member 200 further defines a rotation groove 240, the rotation groove 240 is connected to the channel opening 231, and the rotation groove 240 has two limiting walls 241, the extension portion 330 is rotatably arranged in the rotation groove 240, and the extension portion 330 is located between the two limiting walls 241. Specifically, the extension portion 330 is formed by extending the side wall of the connecting portion 310, and the direction in which the side wall of the connecting portion 310 extends is perpendicular to the axis of the second channel 230. The rotation groove 240 is defined and formed by one of the first shell 211 and the second shell 212. The rotation groove 240 is connected to the channel opening 231, and when the connecting portion 310 is connected to the channel opening 231, the extension portion 330 will be located in the rotation groove 240. The rotation groove 240 has two limiting walls 241, which are separated and the extension portion 330 is located between the two limiting walls 241. The two limiting walls 241 and the inner wall of the rotation groove 240 together define the moving path of the extension portion 330 in the rotation groove 240, that is, the two limiting walls 241 have a limiting effect on the extension portion 330.

[0047] In detail, when the earphone unit 300 and the connecting member 200 are connected and fixed, the connecting portion 310 and the extending portion 330 are located in the passage opening 231 and the rotation groove 240, respectively. When the connecting portion 310 rotates relative to the connecting member 200 around the axis of the second passage 230, the extending portion 330 rotates relative to the connecting member 200 around the axis of the second passage 230 in the rotation groove 240 due to the rotation of the connecting portion 310. However, since the extending portion 330 is located between the two limiting walls 241 of the rotation groove 240, when the extending portion 330 rotates a certain angle following the connecting portion 310, the extending portion 330 abuts against one of the two limiting walls 241. At this time, the limiting wall 241 abutting against the extending portion 330 prevents the extending portion 330 from continuing to rotate around the axis of the second passage 230, thereby stopping the earphone unit 300 from rotating. When the open earphone 10 is used, the speaker of the earphone unit 300 needs to contact the human ear, but the fitting position range of the earphone unit 300 and the human ear is limited, so the adjustment range of the earphone unit 300 relative to the human ear is also limited. The two limiting walls 241 are used to limit the rotation of the extension part 330 to achieve the effect of hindering the rotation of the earphone unit 300, so that the earphone unit 300 can be adjusted only within the fitting range with the human ear, thereby improving the adjustment efficiency of the earphone unit 300. At the same time, since the rotation of the earphone unit 300 needs to be carried out in the cavity of the connecting member 200, the larger the rotation angle of the earphone unit 300, the larger the area of ​​the cavity that needs to be opened in the connecting member 200. Therefore, making the earphone unit 300 adjustable within a certain range can reduce the setting of the cavity in the connecting member 200, so that the connecting member 200 has a thicker thickness, thereby improving the connection strength of the connecting member 200.

[0048] In some embodiments, see Figure 2 , Fig.14 and Fig.15As shown, the open earphone 10 further includes a second damping member 500, which is disposed in the second channel 230 and connected to the connecting portion 310 to limit the self-rotation of the connecting portion 310 relative to the connecting member 200. Specifically, the second damping member 500 is disposed in the second channel 230. A connecting surface is provided between the connecting portion 310 and the second damping member 500, and the connecting portion 310 and the second damping member 500 will generate friction at the connecting surface, so that the connecting portion 310 can rotate relative to the connecting member 200 and the second damping member 500 only when it is rotated by an external force (such as: the rotation of the human body), and in a normal state where the connecting portion 310 is not rotated by an external force, the friction between the second damping member 500 and the connecting portion 310 will prevent the connecting portion 310 from rotating relative to the connecting member 200. As a result, when the open earphone 10 is in use, the position of the earphone unit 300 relative to the connector 200 does not change, thereby ensuring that the open earphone 10 can maintain the same fit with the human ear for a long time, thereby improving the user experience of the open earphone 10.

[0049] Further, in some embodiments, see Fig.11 , Fig.12 and Fig.14 As shown, the second damping member 500 has a second through hole 510, and a protrusion 340 is formed on one side of the connecting portion 310 extending toward the second damping member 500, and the protrusion 340 is arranged on the second through hole 510. Specifically, in this embodiment, the second damping member 500 is made of a material with a high friction coefficient, such as a rubber material, a silicone material or a ceramic material, etc. The second damping member 500 is arranged in the second channel 230, and one end of the second damping member 500 will abut against the inner wall of the second channel 230 along the axial direction of the second channel 230. Since the abutting portion 320 is connected to the connecting portion 310, the abutting portion 320 has an abutting surface 321 on the side facing the second damping member 500. When the second damping member 500 is disposed in the second channel 230 , the other end of the second damping member 500 abuts against the abutting surface 321 , so the second damping member 500 is fixed in the second channel 230 under the cooperation of the abutting surface 321 and the inner wall of the second channel 230 .

[0050] Furthermore, the second through hole 510 passes through the second damping member 500, so that the protrusion 340 can be inserted into the second through hole 510. When the connecting portion 310 rotates relative to the connecting member 200 along the axial direction of the second channel 230, the protrusion 340 will also rotate relative to the second damping member 500 in the second through hole 510, thereby changing the fitting angle and fitting area between the earphone unit 300 and the human ear. Since the second damping member 500 is made of a material with a high friction coefficient, a large friction force is generated between the inner wall of the second through hole 510 and the protrusion 340. This friction force can make the connecting portion 310 rotate relative to the connecting member 200 and the second damping member 500 only when it is rotated by an external force, thereby preventing the connecting portion 310 from rotating relative to the connecting member 200, thereby improving the user experience of the open earphone 10.

[0051] In one example, the connection portion 310 does not include the protrusion 340, the second damping member 500 is disposed in the passage opening 231, and the second damping member 500 is covered on the connection portion 310. Specifically, in this embodiment, the second damping member 500 is also made of a material with a high friction coefficient, and the second damping member 500 has a second through hole 510. When the earphone unit 300 needs to be connected to the second damping member 500, the connection portion 310 is passed through the second through hole 510, and the outer wall of the second damping member 500 abuts against the inner wall of the passage opening 231. When the earphone unit 300 needs to be rotated for adjustment, friction will also be generated between the connecting part 310 and the inner wall of the second through hole 510, and friction will also be generated between the outer wall of the second damping member 500 and the inner wall of the channel opening 231. Under the action of the double friction, the earphone unit 300 also needs to be subjected to external rotational force before it can rotate relative to the connecting part 200. Therefore, this arrangement can also prevent the connecting part 310 from rotating relative to the connecting part 200.

[0052] In other embodiments, the second damping member 500 does not include the second through hole 510, that is, the second damping member 500 is a solid structure. In this embodiment, the second damping member 500 is also made of a material with a high friction coefficient, one end of the second damping member 500 abuts against the inner wall of the second channel 230 along the axis direction of the second channel 230, and the other end is fixedly connected to the protrusion 340. The second damping member 500 is interference-set in the second channel 230 so that friction is generated between the second damping member 500 and the inner wall of the second channel 230. When the earphone unit 300 is rotated and adjusted by the protrusion 340, the protrusion 340 and the second damping member 500 will rotate together in the second channel 230 relative to the connecting member 200 along the axis direction of the second channel 230. Since there is friction between the second damping member 500 and the second channel 230, the second damping member 500 and the protrusion 340 can only rotate when they are rotated by an external force. In a normal state where the protrusion 340 is not rotated by an external force, the friction force generated between the second damping member 500 and the second channel 230 will prevent the protrusion 340 from rotating automatically. Therefore, the second damping member 500 is not provided with the second through hole 510, and the second damping member 500 and the protrusion 340 can be made to move together to prevent the protrusion 340 from rotating automatically, thereby improving the connection stability between the earphone unit 300 and the connecting member 200.

[0053] Similarly, in the case where the second damping member 500 does not include the second through hole 510, the second damping member 500 also does not include the protrusion 340. Specifically, in this embodiment, the length of the connecting portion 310 is less than the length of the passage opening 231, and at the same time, the second damping member 500 is also made of a material with a high friction coefficient. One end of the second damping member 500 will abut against the side of the abutting portion 320 toward the connecting portion 310 along the axial direction of the passage opening 231, and the other end is connected to the connecting portion 310 fixedly connected. The sum of the length of the connecting portion 310 and the length of the second damping member 500 is greater than the length of the passage opening 231, so that there is a gap between the passage opening 231 and the abutting portion 320 bracket. The second damping member 500 is interference-arranged in the passage opening 231 so that friction is generated between the second damping member 500 and the inner wall of the passage opening 231. When the earphone unit 300 is rotated and adjusted through the connecting portion 310, the connecting portion 310 and the second damping member 500 will rotate together in the channel opening 231 relative to the connecting member 200 along the axial direction of the channel opening 231. Since there is friction between the second damping member 500 and the inner wall of the channel opening 231, the second damping member 500 and the connecting portion 310 can only rotate when they are rotated by external force. In the normal state where the connecting portion 310 is not rotated by external force, the friction between the second damping member 500 and the inner wall of the channel opening 231 will hinder the connecting portion 310 from rotating by itself. In this way, the function of preventing the earphone unit 300 from rotating by itself relative to the connecting member 200 through the connecting portion 310 can be achieved.

[0054] In another embodiment, see Fig.15 As shown, the connecting portion 310 has an abutting surface 321 on one side facing the second damping member 500, and the second damping member 500 abuts against the abutting surface 321, and applies an external force to the abutting surface 321 along the axial direction of the second channel 230. Specifically, in this embodiment, the second damping member 500 is an elastic part, specifically a spring. The second damping member 500 is arranged in the second channel 230, and one end of the second damping member 500 abuts against the inner wall of the second channel 230 along the axial direction of the second channel 230. At the same time, the abutting portion 320 is connected to the connecting portion 310, and the connecting portion 310 and the abutting portion 320 are fixedly connected. In other embodiments, the connecting portion 310 and the abutting portion 320 can also be detachably connected, such as: bonding, or clamping.

[0055] Furthermore, the side of the abutting portion 320 facing the second damping member 500 has an abutting surface 321, and the other end of the second damping member 500 abuts against the abutting surface 321, so the second damping member 500 is fixed in the second channel 230 under the cooperation of the abutting surface 321 and the inner wall of the second channel 230. At the same time, since the second damping member 500 is a specific elastic part, when the second damping member 500 is between the abutting surface 321 and the inner wall of the second channel 230, the abutting surface 321 and the inner wall of the second channel 230 will squeeze the second damping member 500, so that the second damping member 500 is in an extruded state and has a tendency to return to the original state. Therefore, the second damping member 500 also applies an external force to the abutting surface 321, so that the side of the abutting portion 320 away from the second damping member 500 abuts against the inner wall of the channel opening 231 along the axial direction of the second channel 230. At this time, the abutment portion 320 is located between the second damping member 500 and the inner wall of the channel opening 231. Since the abutment surface 321 is subjected to the external force applied by the second damping member 500, the abutment portion 320 will also exert an external force on the inner wall of the channel opening 231, and the abutment portion 320 will be subjected to a reaction force from the inner wall of the channel opening 231. Therefore, there will be friction between the inner wall of the channel opening 231 and the abutment portion 320.

[0056] When the earphone unit 300 needs to be rotated and adjusted, since the second damping member 500 abuts against the abutting surface 321 and the second damping member 500 also applies an external force to the abutting surface 321, a large friction force will be generated between the second damping member 500 and the abutting surface 321. At the same time, since the abutting surface 321 abuts against the inner wall of the passage opening 231, a friction force is also generated between the abutting surface 321 and the inner wall of the passage opening 231. The friction force generated between the second damping member 500 and the abutting surface 321 and the friction force generated between the abutting surface 321 and the inner wall of the passage opening 231, and the two friction forces have the same direction, act together on the abutting surface 321, thereby preventing the earphone unit 300 from rotating relative to the connecting member 200 and the second damping member 500. As a result, the connecting portion 310 and the abutting portion 320 can slide relative to the connecting member 200 and the second damping member 500 only when they are rotated by an external force.

[0057] In some embodiments, see Figure 2As shown, the open earphone 10 further includes a kit 600, and the kit 600 is coated on the connector 200. Specifically, the interior of the kit 600 has a hollow structure, that is, the interior of the kit 600 has a cavity, and the cavity runs through both ends of the kit 600 to form a hollow structure. The connector 200 is located in the hollow structure, and the kit 600 is sleeved on the outer wall of the shell 210, thereby coating the shell 210. In this embodiment, after the first shell 211 and the second shell 212 are assembled to form the shell 210, the kit 600 will be coated on the outer wall surface of the shell 210 to hide the connection gap between the first shell 211 and the second shell 212, so as to prevent dust particles and moisture from entering the interior of the shell 210 through the connection gap between the first shell 211 and the second shell 212, thereby protecting the connector 200. When the kit 600 is put on the shell 210, the cover body 220 is connected to the shell 210. The cover body 220 will abut the first end 201 of the kit 600 on the shell 210. Since the second end 202 of the shell 210 is connected to the earphone unit 300, the kit 600 will also abut the second end 202 of the shell 210. The earphone unit 300 and the cover body 220 cooperate with each other to jointly restrict the kit 600 on the shell 210 to prevent the kit 600 from sliding along the axial direction of the shell 210 to separate from the shell 210.

[0058] In this embodiment, the material of the kit 600 is made of stainless steel. Using stainless steel as the material can make the kit 600 have good oxidation resistance and corrosion resistance, and stainless steel can effectively resist the corrosion of oxides and acid and alkali substances in water, ensuring the long-term use of the kit 600. This greatly reduces the frequency of maintenance and replacement of the kit 600. At the same time, the use of stainless steel can further protect the housing 210 by the kit 600, saving time and economic costs. In other embodiments, the material of the kit 600 can also be made of aluminum alloy, metal copper and metal iron.

[0059] In an embodiment of the present invention, the material of the bracket 100 is made of titanium. Since titanium has the advantages of low density and light weight, the wearing burden of the open-type earphone 10 can be reduced when wearing it, and it is suitable for long-term wearing. At the same time, titanium has high strength and hardness, can withstand great pressure and friction, can effectively resist deformation and distortion in daily use, ensure the stability of the structure, and thus ensure that the bracket 100 can be adapted to different head shapes. In other embodiments, the bracket 100 can also be made of stainless steel, aluminum alloy, carbon and other materials.

[0060] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
