[0044] The open earphone 10 of the first aspect embodiment of the utility model will be described below with reference to the accompanying drawings of the specification.

[0045] Referring to Figures 1 to 6As shown, the utility model embodiment provides an open earphone 10, the open earphone 10 includes earphone unit 300, connecting piece 200 and support 100. Among them, one end of connecting piece 200 is connected to earphone unit 300, and the other end is connected to support 100, and the inside of connecting piece 200 is limited to first channel 2121. First channel 2121 is used for the activity of support 100 to make the user can adjust the support 100 of open earphone 10 by sliding support 100, so that open earphone 10 is adapted to head size. Support 100 has two connecting ends 110, two connecting ends 110 are connected with earphone unit 300 respectively, earphone unit 300 is arranged separately between earphone unit 300, and is connected by wireless mode. Among them, at least one connecting end 110 is connected with connecting piece 200, and the connecting end 110 is connected with earphone unit 300 through connecting piece 200. Connecting end 110 is arranged in first channel 2121, wherein, connecting end 110 can reciprocate along first channel 2121, so as to change the area of support 100 exposed outside first channel 2121, that is, support 100 can be connected with connecting piece 200 in first channel 2121 along the axis direction of first channel 2121 through connecting end 110, so as to change the length of support 100 exposed to the outside to change the wearing size of open earphone 10, so that open earphone 10 is adapted to the head of the user.

[0046] Specifically, in one example, the number of connecting ends 110 of support 100 is two, and two connecting ends 110 are arranged separately. Two connecting ends 110 are connected with connecting piece 200, one end of connecting piece 200 is connected to support 100, and the other end is connected to earphone unit 300. Among them, the number of earphone unit 300 is also two, two earphone unit 300 are connected to different connecting pieces 200 respectively, but are connected to the same support 100, and connecting piece 200 is detachably connected to support 100 and earphone unit 300. At the same time, two earphone unit 300 are connected by wireless communication mode. When open earphone 10 needs to be used, the wearing size of open earphone 10 can be adjusted by controlling support 100 to slide in first channel 2121 relative to connecting piece 200 along the axis direction of first channel 2121, so that open earphone 10 can be adapted to the head of the user for use.

[0047] In another embodiment, the number of the connecting ends 110 of the support 100 is two, and the two connecting ends 110 are arranged separately. Among them, only one connecting end 110 is connected with the connecting piece 200, and the other connecting end 110 is directly connected with the earphone unit 300. The connecting end 110 connected with the connecting piece 200 is indirectly connected with the earphone unit 300 through the connecting piece 200. The connecting end 110 is arranged in the first channel 2121, and the connecting end 110 can slide along the axis direction of the first channel 2121 relative to the connecting piece 200. Thus, the support 100 of this embodiment can also adjust the size of the wearing size of the open earphone 10, so that the open earphone 10 can be adapted to the user's head for use.

[0048] In a conventional headset or a neck-hanging earphone, wires are embedded in the support of the earphone, and the earphone is connected with two earphone units through the wires, so that the two earphone units can be connected in communication. In addition, the earphone also needs to transmit power signals and audio data signals through the wires. However, when the support or one of the earphone units is damaged, the entire earphone cannot be used, and the entire earphone needs to be repaired or replaced, which is complex and time-consuming to operate. In a conventional wireless connection open earphone, the open earphone only includes two earphone units in appearance, and the two earphone units are wirelessly connected through internal parts, but the safety of such an open earphone is low. When outdoor activities or exercises are performed, the earphone unit is easy to be separated from the ear, and thus falling or loss may occur.

[0049] Compared with a conventional headset, the support 100 of the embodiment of the present application does not need to embed wires for connecting 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 in a wireless manner, and the support 100, the connecting piece 200 and the earphone unit 300 are detachably connected, so that when the open earphone 10 is damaged, the damaged parts can be individually repaired, without affecting the overall use of the open earphone 10. Compared with a conventional wireless transmission earphone, the earphone unit 300 of the embodiment of the present application is connected through the support 100, which can improve the safety of the earphone unit 300, so that the earphone unit 300 is not easy to fall during use, and the safety is high. Therefore, the open earphone 10 provided by the embodiment of the present application can not only ensure the safety of the earphone use, but also can individually repair the damaged parts when the earphone is damaged, without affecting the overall use.

[0050] It should be noted that as one of the examples, the subsequent embodiments will be described taking that both the connecting ends 110 are connected with the connecting piece 200 as an example.

[0051] In some embodiments, referring to Figure 2 , Figure 11 and Figure 12 , the open earphone 10 further comprises a first damping member 400 connected to the side of the connecting member 200 away from the earphone unit 300, the first damping member 400 has a first through hole 410 passing through both ends of the first damping member 400, and the connecting end 110 can be arranged in the first damping member 400 through the first through hole 410. Specifically, the first damping member 400 is arranged at the end of the connecting member 200, and the support 100 is movably arranged in the first through hole 410. When the support 100 slides along the axis direction of the first channel 2121 relative to the connecting member 200, the support 100 also slides in the first through hole 410 relative to the first damping member 400 to change the size of the wearing size of the open earphone 10.

[0052] The first damping member 400 is made of a material with a high friction coefficient, such as rubber material, silica gel material, or ceramic material, etc. Making the first damping member 400 from a material with a high friction coefficient can generate a large friction force between the inner wall of the first through hole 410 and the support 100 when the support 100 and the first damping member 400 are connected and contacted with each other, so that the support 100 can only slide relative to the connecting member 200 and the first damping member 400 when it is pulled by an external force (such as the pulling of the human body), and in the normal state when the support 100 is not pulled by an external force, there will also be a friction force between the inner wall of the first through hole 410 and the support 100, which will hinder the support 100 from sliding relative to the connecting member 200. Thus, when the open earphone 10 is used, the support 100 and the connecting member 200 are always in the same connected position and will not automatically change, thereby ensuring that the open earphone 10 can maintain the same fitting degree with the human head for a long time. At the same time, since the support 100 can slide relative to the connecting member 200, when the open earphone 10 needs to be stored, the support 100 can slide along the first channel 2121 so that most of the support 100 is accommodated in the first channel 2121, thereby reducing the overall volume of the open earphone 10 to facilitate storage, and through the first damping member 400, the support 100 will not automatically slide relative to the connecting member 200, so that the open earphone 10 always maintains the volume in the storage state, improving the use experience.

[0053] In some embodiments, the first damping member 400 can 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 fixedly connected to the connecting end 110 of the support 100, and the first damping member 400 and the connecting end 110 are arranged in the first channel 2121 together, and the first damping member 400 is arranged in the first channel 2121 in an interference manner so that a friction force is generated between the first damping member 400 and the inner wall of the first channel 2121. When the support 100 is adjusted through the connecting end 110, since the first damping member 400 is fixedly connected to the connecting end 110 of the support 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 axis direction of the first channel 2121. Since there is a friction force between the first damping member 400 and the first channel 2121, the first damping member 400 and the support 100 also need to slide under the action of an external force. In the normal state where the support 100 is not pulled by an external force, the friction force between the first damping member 400 and the first channel 2121 will hinder the support 100 from sliding by itself. Therefore, by not arranging the first through hole 410 on the first damping member 400 and by fixedly connecting the first damping member 400 and the support 100, the common movement of the first damping member 400 and the support 100 can also hinder the support 100 from sliding by itself, thereby improving the connection strength and stability of the support 100 and the connecting member 200.

[0054] In some embodiments, as shown in Figure 2 、 Figure 4 and Figure 6 , the connecting member 200 includes a housing 210 and a cover 220, and the housing 210 and the cover 220 are connected, wherein the inside of the housing 210 defines a first channel 2121, the inside of the cover 220 defines a receiving cavity 221, the first channel 2121 is open at one end of the housing 210 so as to communicate with the receiving cavity 221, and the first damping member 400 is arranged in the receiving cavity 221. Specifically, in one example, as shown in Figure 4 , the housing 210 has a first shell 211 and a second shell 212, and the first shell 211 and the second shell 212 are detachably connected, and the first shell 211 and the second shell 212 jointly define the first channel 2121. In this embodiment, the first shell 211 and the second shell 212 are connected by screws. In other embodiments, the first shell 211 and the second shell 212 can also be connected by buckling, or magnetic attraction, or a sliding groove.

[0055] Further, the shell 210 has a first end 201 and a second end 202, the first end 201 and the second end 202 are oppositely arranged, the cover 220 is detachably connected to the first end 201 of the shell 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 shell 210, the cover 220 is connected and fixed with the shell 210 through threaded connection. Further, the first passage 2121 leads to the first end 201 of the shell 210, so that the first passage 2121 and the accommodating cavity 221 are in communication, thereby allowing the connecting end 110 of the support 100 to pass through the accommodating cavity 221 and enter the first passage 2121. The first damping member 400 is interference-fitted in the accommodating cavity 221, and the outer wall of the first damping member 400 is in close contact with the inner wall of the accommodating cavity 221. Since the first damping member 400 is made of a material with high friction coefficient, the first damping member 400 will generate friction with the inner wall of the accommodating cavity 221. At the same time, since the volume of the accommodating cavity 221 is matched with the volume of the first damping member 400, the accommodating cavity 221 also limits the first damping member 400, thereby preventing the first damping member 400 from sliding along the axial direction of the accommodating cavity 221 relative to the cover 220. At the same time, since the cover 220 is connected to the first end 201 of the shell 210, when the first damping member 400 is arranged in the accommodating cavity 221, the first end 201 of the shell 210 will abut against the first damping member 400, thereby further fixing the first damping member 400 in the accommodating cavity 221.

[0056] In other embodiments, the connecting member 200 does not include the cover 220, and the first damping member 400 is arranged in the first passage 2121. Specifically, the first damping member 400 is interference-fitted in the first passage 2121. Since the first damping member 400 is made of a material with high friction coefficient, the first damping member 400 and the inner wall of the first passage 2121 will generate friction, thereby preventing the first damping member 400 from sliding in the first passage 2121 relative to the connecting member 200 along the axial direction of the first passage 2121. In this embodiment, the first damping member 400 is movably connected with the inner wall of the first passage 2121. Since the first damping member 400 needs to be connected with the support 100, the first damping member 400 is fixedly connected with the support 100 in this embodiment. Therefore, when the support 100 is adjusted in extension and contraction, the first damping member 400 will also move together with the support 100, and the first damping member 400 is made of a material with high friction coefficient in order to generate friction between the first damping member 400 and the inner wall of the first passage 2121, so as to prevent the first damping member 400 and the support 100 from sliding by themselves without external force. Therefore, by not arranging the cover 220 and arranging the first damping member 400 in the first passage 2121, the first damping member 400 can also operate normally.

[0057] In another embodiment, the connector 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 passes through the first through hole 410, friction is generated between the bracket 100 and the inner wall of the first through hole 410. When the bracket 100 is extended or retracted, the bracket 100 will slide relative to the first damping member 400 and the connector 200 in the first channel 2121 and the first through hole 410 along the axial 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 coefficient of friction in order to generate friction between the first damping member 400 and the bracket 100 to prevent the bracket 100 from sliding on its own without the action of external force.

[0058] In some embodiments, see Figure 6 , Figure 7 and Figure 13 As shown, the connecting end 110 includes a limiting portion 111, which is formed by the outer wall of the connecting end 110 protruding along the axis perpendicular to the first channel 2121. The inner wall of the first channel 2121 is recessed along the axis perpendicular to the first channel 2121 to form a limiting groove 250. The limiting portion 111 is accommodated in the limiting groove 250 and is configured to restrict the connecting end 110 from rotating relative to the connecting member 200. Specifically, the limiting portion 111 is formed by the protrusion of the outer wall of the connecting end 110, and the direction in which the outer wall of the connecting end 110 protrudes to form the limiting portion 111 is perpendicular to the sliding direction of the connecting 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 connecting end 110. The limiting grooves 250 and the limiting portions 111 are in the same orientation and number, so that after the connecting end 110 is placed in the first channel 2121, the limiting portions 111 can also be placed precisely in the limiting grooves 250. When the connecting end 110 slides in the first channel 2121, the limiting portions 111 also slide with the connecting end 110, but the limiting portions 111 do not slide in the limiting grooves 250. In this embodiment, the limiting grooves 250 do not connect to the first end 201 of the housing 210. Therefore, when the limiting portion 111 slides to one end in the limiting grooves 250, the sidewalls of the limiting grooves 250 along the axial direction will prevent the limiting portion 111 from continuing to slide, thereby preventing the limiting portion 111 from separating from the limiting grooves 250.

[0059] Further, the limiting groove 250 has two side walls, and the limiting portion 111 is located between the two side walls of the limiting groove 250. The limiting portion 111 is in clearance fit with the limiting groove 250, that is, when the limiting portion 111 is accommodated in the limiting groove 250, the limiting portion 111 has a clearance with the two side walls of the limiting groove 250, so that the limiting portion 111 can move relative to the limiting groove 250, and the friction between the limiting portion 111 and the limiting groove 250 is avoided to cause abrasion of 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 piece 200 about the axis of the first channel 2121, the two side walls of the limiting groove 250 abut against the limiting portion 111, so as to limit the rotation of the limiting portion 111. Since the support 100 has two connecting ends 110, if the limiting portion 111 rotates relative to the connecting piece 200, the connecting ends 110 of the support 100 are also driven to rotate by the limiting portion 111. When the support 100 rotates, torsional stress is generated on the support 100, so that the rotation of the limiting portion 111 relative to the connecting piece 200 about the axis of the second channel 230 is hindered, and the superposition of torsional stress during the rotation of the support 100 is avoided, so that the support 100 is not damaged and broken.

[0060] In some embodiments, referring to Figures 4 to 6 As shown, the connecting piece 200 is connected to one side of the earphone unit 300, and the second channel 230 is arranged at the second end 202 of the shell 210, and the second channel 230 is used to connect the earphone unit 300. Specifically, the first shell 211 and the second shell 212 cooperatively define the second channel 230 at the second end 202 of the shell 210, and the first channel 2121 is arranged separately from the second channel 230. The support 100 can slide in the first channel 2121 to change the wearing size of the open earphone 10, so as to adapt the open earphone 10 to the head of the user. The earphone unit 300 can move in the second channel 230 to change the fitting position of the earphone unit 300 to the ear of the user, so as to improve the use effect. Therefore, by arranging the first channel 2121 and the second channel 230 separately, when the first end 201 and the second end 202 of the connecting piece 200 are connected to the support 100 and the earphone unit 300 respectively, the user can adjust the support 100 and the earphone unit 300 separately, so that the support 100 and the earphone unit 300 do not affect each other during the adjustment.

[0061] Further, referring to Figure 9 and Figure 10As shown, the earphone unit 300 is provided with a connecting portion 310, which is rotatably arranged in the second channel 230 due to the connection of the connecting member 200. Specifically, the side of the earphone unit 300 facing the connecting member 200 is provided with the connecting portion 310, which is accommodated in the second channel 230 when the connecting member 200 and the earphone unit 300 are connected and assembled, and the connecting portion 310 can rotate in the second channel 230 relative to the connecting member 200 about the axis direction of the second channel 230, thereby driving the whole earphone unit 300 to rotate relative to the connecting member 200, so as to change the fitting angle and fitting area of the earphone unit 300 with the ear. It should be noted that the first channel 2121 and the second channel 230 are arranged in parallel and spaced apart, 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 shell 210.

[0062] In some embodiments, referring to Figure 4 and Figure 6 As shown, the second channel 230 is formed with a channel opening 231 on the side where the connecting member 200 is connected to the connecting portion 310, i.e., the second end 202 of the connecting member 200 is formed with the channel opening 231, which is in communication with the outside, so that part of the structure of the earphone unit 300 can be connected to the second channel 230 through the channel opening 231. It should be noted that, and in this embodiment, the channel opening 231 is a solid structure with thickness and length. The inner diameter of the channel opening 231 is formed with the axis of the second channel 230 as the center, and the length is 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 connecting portion 310 is connected to the connecting member 200, the connecting portion 310 is rotatably arranged in the channel opening 231. Since the channel opening 231 is formed by the second channel 230 leading through the second end 202 of the shell 210, the channel opening 231 also belongs to part of the second channel 230.

[0063] Further, referring to Figure 10 , Figure 12 and Figure 14As shown, the earphone unit 300 further comprises an abutting portion 320 connected to the connecting portion 310 at one end of the connecting portion 310 which is rotatably arranged at the channel opening 231, and the abutting portion 320 is arranged in the second channel 230. Specifically, in one example, the abutting portion 320 is rotatably arranged 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, after the abutting portion 320 is accommodated in the second channel 230, the abutting portion 320 is limited in the second channel 230 by the cooperation of the first shell 211 and the second shell 212, and since 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 sliding the abutting portion 320 along the axis of the second channel 230 towards the channel opening 231, the abutting portion 320 will abut 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 gap-connected, and 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, thereby allowing the connecting portion 310 to rotate around the axis of the second channel 230 in the channel opening 231 relative to the connecting member 200 to change the fitting angle and area of the earphone unit 300 with the human ear.

[0064] Further, the connecting portion 310 has a length along the axis direction of the second channel 230, and the length of the connecting portion 310 is greater than the length of the channel opening 231 along the axis direction of the second channel 230. Since the abutting portion 320 is connected to the connecting portion 310, the length of the connecting portion 310 being greater than the length of the channel opening 231 can cause a gap between the channel opening 231 and the abutting portion 320 along the axis direction of the second channel 230 after the connecting portion 310 is connected to the channel opening 231, i.e., the abutting portion 320 can be displaced relative to the connecting member 200 along the axis direction of the second channel 230 after the earphone unit 300 and the connecting member 200 are connected, thereby avoiding the abutting portion 320 directly abutting against the inner wall of the channel opening 231 along the axis 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, a frictional force can be generated between 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, the gap between the channel opening 231 and the abutting portion 320 along the axis direction of the second channel 230 and the absence of frictional force between them can avoid the frictional force between the abutting portion 320 and the channel opening 231 against the inner wall of the channel opening 231 when the connecting portion 310 rotates relative to the connecting member 200, thereby avoiding the abrasion of the inner wall of the channel opening 231.

[0065] In some embodiments, Figure 8 、 Figures 10 to 15 As shown in FIG. 6, the side wall of the connecting portion 310 is provided with an extension 330 in a direction perpendicular to the axis direction of the second channel 230, and the connecting member 200 further defines a rotating groove 240, which is in communication with the channel opening 231, and the rotating groove 240 has two limiting walls 241, and the extension 330 is rotatably arranged in the rotating groove 240 and located between the two limiting walls 241. Specifically, the extension 330 is formed by the extension of the side wall of the connecting portion 310, and the extension direction of the side wall of the connecting portion 310 is perpendicular to the axis direction of the second channel 230. The rotating groove 240 is defined by one of the first housing 211 and the second housing 212. The rotating groove 240 is in communication with the channel opening 231, and when the connecting portion 310 is connected to the channel opening 231, the extension 330 is located in the rotating groove 240. The rotating groove 240 has two limiting walls 241, which are separately arranged, and the extension 330 is located between the two limiting walls 241. The two limiting walls 241 and the inner wall of the rotating groove 240 together define the movement path of the extension 330 in the rotating groove 240, i.e., the two limiting walls 241 limit the extension 330.

[0066] In detail, when the earphone unit 300 and the connecting piece 200 are connected and fixed, the connecting part 310 and the extending part 330 are located in the channel opening 231 and the rotating groove 240 respectively, and when the connecting part 310 rotates relative to the connecting piece 200 around the axis of the second channel 230, the extending part 330 rotates relative to the connecting piece 200 around the axis of the second channel 230 in the rotating groove 240 due to the rotation of the connecting part 310. However, since the extending part 330 is located between the two limiting walls 241 of the rotating groove 240, when the extending part 330 rotates with the connecting part 310 through a certain angle, the extending part 330 will abut against one of the two limiting walls 241, and at this time, the limiting wall 241 abutting against the extending part 330 will hinder the extending part 330 from continuing to rotate around the axis of the second channel 230, so that the earphone unit 300 stops rotating. Since the speaker of the earphone unit 300 needs to contact the human ear when the open earphone 10 is used, but the range of the fitting position of the earphone unit 300 to the human ear is limited, the adjustment range of the earphone unit 300 relative to the human ear is also limited. The rotation of the extending part 330 is limited by the two limiting walls 241 to hinder the rotation of the earphone unit 300, so that the earphone unit 300 can only be adjusted within the fitting range of the human ear, and the adjustment efficiency of the earphone unit 300 is improved. At the same time, since the rotation of the earphone unit 300 needs to be performed in the cavity of the connecting piece 200, if the rotation angle of the earphone unit 300 is larger, the area of the cavity to be opened in the connecting piece 200 is larger, so that the adjustment of the earphone unit 300 within a certain range can reduce the setting of the cavity in the connecting piece 200, so that the connecting piece 200 has a larger thickness, and the connecting strength of the connecting piece 200 is improved.

[0067] In some embodiments, referring to Figure 2 、 Figure 14 and Figure 15As shown, the open earphone 10 further comprises a second damping member 500, which is arranged in the second channel 230 and connected to the connecting part 310 to limit the self-rotation of the connecting part 310 relative to the connecting member 200. Specifically, the second damping member 500 is arranged in the second channel 230. The connecting part 310 and the second damping member 500 have a connecting surface therebetween, and the connecting part 310 and the second damping member 500 generate a friction force at the connecting surface, so that the connecting part 310 can only rotate relative to the connecting member 200 and the second damping member 500 when it is subjected to external force (e.g., the rotation of the human body), and in the normal state where the connecting part 310 is not subjected to external force, the friction force between the second damping member 500 and the connecting part 310 hinders the self-rotation of the connecting part 310 relative to the connecting member 200. Thus, the position of the earphone unit 300 relative to the connecting member 200 of the open earphone 10 does not change when the open earphone 10 is used, thereby ensuring that the open earphone 10 can maintain the same fitting degree with the human ear for a long time and improving the use experience of the open earphone 10.

[0068] Further, in some embodiments, referring to Figure 11 , Figure 12 and Figure 14 As shown, the second damping member 500 has a second through hole 510, and the connecting part 310 has a protruding part 340 extending from the side facing the second damping member 500, and the protruding part 340 is arranged in the second through hole 510. Specifically, in this embodiment, the second damping member 500 is made of a material with high friction coefficient, such as rubber material, silica gel material, or ceramic material, etc. 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. Since the connecting part 310 is connected with the abutting part 320, the side of the abutting part 320 facing the second damping member 500 has an abutting surface 321. When the second damping member 500 is arranged in the second channel 230, the other end of the second damping member 500 abuts against the abutting surface 321, so that the second damping member 500 is fixed in the second channel 230 by the cooperation of the abutting surface 321 and the inner wall of the second channel 230.

[0069] Further, the second through hole 510 penetrates the second damping member 500, so that the protruding part 340 can be arranged in the second through hole 510. When the connecting part 310 rotates relative to the connecting member 200 along the axis direction of the second channel 230, the protruding part 340 also rotates in the second through hole 510 relative to the second damping member 500, so as to change the fitting angle and fitting area of the earphone unit 300 and the human ear. Since the second damping member 500 is made of a material with high friction coefficient, a large friction force is generated between the inner wall of the second through hole 510 and the protruding part 340, which can make the connecting part 310 rotate relative to the connecting member 200 and the second damping member 500 only when an external force is applied, so as to prevent the connecting part 310 from rotating relative to the connecting member 200 by itself, thereby improving the use experience of the open earphone 10.

[0070] In one example, the connecting part 310 does not include the protruding part 340, the second damping member 500 is arranged in the channel opening 231, and the second damping member 500 covers the connecting part 310. Specifically, in this embodiment, the second damping member 500 is also made of a material with high friction coefficient, and the second damping member 500 has a second through hole 510. When the earphone unit 300 needs to be connected with the second damping member 500, the connecting part 310 is arranged in the second through hole 510, and the outer wall of the second damping member 500 abuts against the inner wall of the channel opening 231. When the earphone unit 300 needs to be rotated for adjustment, the connecting part 310 and the inner wall of the second through hole 510 generate a friction force, and the outer wall of the second damping member 500 and the inner wall of the channel opening 231 also generate a friction force, so that the earphone unit 300 needs to be subjected to an external rotating force to rotate relative to the connecting member 200, and thus this arrangement can also prevent the connecting part 310 from rotating relative to the connecting member 200 by itself.

[0071] In other embodiments, the second damping member 500 does not include the second through hole 510, i.e. 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 axial direction of the second channel 230, and the other end is fixedly connected to the protruding portion 340. The second damping member 500 is provided in the second channel 230 in an interference fit, so that a frictional force is generated between the second damping member 500 and the inner wall of the second channel 230. When the earphone unit 300 is adjusted to rotate through the protruding portion 340, the protruding portion 340 and the second damping member 500 will jointly rotate in the second channel 230 relative to the connecting member 200 along the axial direction of the second channel 230. Since there is a frictional force between the second damping member 500 and the second channel 230, the second damping member 500 and the protruding portion 340 also need to be rotated under the action of an external force. In the normal state where the protruding portion 340 is not rotated by an external force, the frictional force between the second damping member 500 and the second channel 230 will hinder the protruding portion 340 from rotating by itself. Therefore, by not providing the second damping member 500 with the second through hole 510, the joint movement of the second damping member 500 and the protruding portion 340 can also hinder the protruding portion 340 from rotating by itself, thereby improving the connection stability of the earphone unit 300 and the connecting member 200.

[0072] Similarly, when 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 channel opening 231, and the second damping member 500 is also made of a material with a high coefficient of friction. One end of the second damping member 500 abuts against the side of the abutment portion 320 facing the connecting portion 310 along the axial direction of the channel opening 231, and the other end is connected to and fixedly connected to the connecting portion 310. 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 channel opening 231, thereby creating a gap between the channel opening 231 and the abutment portion 320 support. The second damping member 500 is interference-fitted into the channel opening 231, thereby generating friction between the second damping member 500 and the inner wall of the channel opening 231. When the headphone unit 300 is rotated and adjusted via the connecting part 310, the connecting part 310 and the second damping member 500 rotate together relative to the connecting member 200 along the axis of the channel opening 231. Due to the friction between the second damping member 500 and the inner wall of the channel opening 231, both the second damping member 500 and the connecting part 310 require an external force to rotate. In the normal state where the connecting part 310 is not subjected to an external force, the friction between the second damping member 500 and the inner wall of the channel opening 231 prevents the connecting part 310 from rotating on its own. This also achieves the function of preventing the headphone unit 300 from rotating relative to the connecting member 200 via the connecting part 310.

[0073] In another embodiment, see Figure 15 As shown, the connecting portion 310 has an abutment surface 321 on the side facing the second damping member 500. The second damping member 500 abuts against the abutment surface 321 and applies an external force to the abutment surface 321 along the axial direction of the second channel 230. Specifically, in this embodiment, the second damping member 500 is an elastic component, specifically a spring. The second damping member 500 is disposed 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. Simultaneously, the connecting portion 310 is connected to the abutment portion 320, and the connecting portion 310 and the abutment portion 320 are fixedly connected. In other embodiments, the connecting portion 310 and the abutment portion 320 may also be detachably connected, such as by adhesive bonding or snap-fit.

[0074] Further, the abutting portion 320 has an abutting surface 321 on the side facing the second damping member 500, and the other end of the second damping member 500 abuts against the abutting surface 321, so that the second damping member 500 is fixed in the second passage 230 by the cooperation of the abutting surface 321 and the inner wall of the second passage 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 passage 230, the abutting surface 321 and the inner wall of the second passage 230 will extrude 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 passage opening 231 along the axis direction of the second passage 230. At this time, the abutting portion 320 is between the second damping member 500 and the inner wall of the passage opening 231, and since the abutting surface 321 is subjected to the external force applied by the second damping member 500, the abutting portion 320 also applies an external force to the inner wall of the passage opening 231, and the abutting portion 320 is subjected to the reaction force from the inner wall of the passage opening 231, so that the inner wall of the passage opening 231 and the abutting portion 320 have a frictional force therebetween.

[0075] When the earphone unit 300 needs to be adjusted in rotation, 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 larger frictional force is 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 frictional force is also generated between the abutting surface 321 and the inner wall of the passage opening 231. The frictional force generated between the second damping member 500 and the abutting surface 321 and the frictional force generated between the abutting surface 321 and the inner wall of the passage opening 231 have the same direction and act on the abutting surface 321 together, thereby hindering the earphone unit 300 from rotating relative to the connecting member 200 and the second damping member 500 by itself. Thus, the connecting portion 310 and the abutting portion 320 can only slide relative to the connecting member 200 and the second damping member 500 when they are subjected to an external force to rotate.

[0076] In some embodiments, referring to Figure 2As shown, the open earphone 10 further comprises a sleeve 600, which is sleeved on the connecting piece 200. Specifically, the interior of the sleeve 600 has a hollow structure, i.e., the interior of the sleeve 600 has a cavity that penetrates through both ends of the sleeve 600 to form a hollow structure. The connecting piece 200 is located in the hollow structure, and the sleeve 600 is sleeved on the outer wall of the shell 210 to cover the shell 210. In this embodiment, when the first shell 211 and the second shell 212 are assembled to form the shell 210, the sleeve 600 will cover the outer wall surface of the shell 210 to hide the connection gap of 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 of the first shell 211 and the second shell 212, and to protect the connecting piece 200. When the sleeve 600 is sleeved on the shell 210, the cover 220 is connected to the shell 210, and the cover 220 will abut against the sleeve 600 at the first end 201 of the shell 210. Since the second end 202 of the shell 210 is connected to the earphone unit 300, the sleeve 600 will also abut against the earphone unit 300 at the second end 202 of the shell 210. The earphone unit 300 and the cover 220 cooperate with each other to limit the sleeve 600 on the shell 210, so as to prevent the sleeve 600 from sliding along the axial direction of the shell 210 to separate from the shell 210.

[0077] In this embodiment, the material of the sleeve 600 is made of stainless steel. Using stainless steel as the material can make the sleeve 600 have good oxidation resistance and corrosion resistance, and stainless steel can effectively resist the erosion of oxides and acid-base substances in water, ensuring the long-term use of the sleeve 600. This greatly reduces the frequency of maintenance and replacement of the sleeve 600. At the same time, using stainless steel can further protect the sleeve 600 from the shell 210, saving time and economic cost. In other embodiments, the material of the sleeve 600 can also be made of aluminum alloy, metal copper, and metal iron.

[0078] In the embodiment of the utility model, the material of the support 100 is made of metal titanium. Because metal titanium has the advantages of small density and light weight, the wearing burden can be reduced when wearing the open earphone 10, and it is suitable for long-time wearing. At the same time, metal titanium has high strength and hardness, can withstand a lot of pressure and friction, can effectively resist deformation and distortion in daily use, ensures the stability of the structure, and thus ensures that the support 100 can be adapted to different head shapes. In other embodiments, the support 100 can also be made of stainless steel, or aluminum alloy, or carbon.

[0079] The utility model embodiment has been explained in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiment, still can make various changes in the knowledge range of the ordinary skill in the art who possesses under the premise of not departing from the utility model's tenet. Besides, the embodiment and the feature in the embodiment of the utility model can be combined mutually under the condition of not conflicting.
