[0029] As shown in Figure 1 The utility model discloses an earphone, including earphone monomer 100 and connector 200.

[0030] The number of earphone monomers 100 is two, one earphone monomer 100 is suitable for being worn in the left ear of the user, and the other earphone monomer 100 is suitable for being worn in the right ear of the user, and the earphone monomer 100 can sound.

[0031] It should be noted that the earphone monomer 100 is a Bluetooth earphone, which can be an in-ear earphone or an open earphone.

In addition, the earphone monomer 100 can be a smart earphone, which can be configured with a call noise reduction function and / or an artificial intelligence noise reduction function, and can also be configured with a stereo surround function.

[0032] The two ends of the connector 200 are detachably connected with the two earphone monomers 100 respectively.

[0033] It can be understood that the connector 200 is used to connect the two earphone monomers 100 together, and the earphone monomer 100 can also be separated from the connector 200, and the two earphone monomers 100 can be used separately from the connector 200.

[0034] The earphone is convenient to use, and the two earphone monomers 100 can be respectively worn on the left ear and the right ear of a user when the user uses the earphone in daily life.

[0035] It should be noted that the connector 200 is provided in a structure having a clamping effect, specifically, the connector 200 is in an arc-shaped belt or strip structure and is made of a material capable of elastic deformation such as steel or plastic, and the connector 200 can be clamped on the neck of the user, thereby reducing the risk of the earphone falling off.

[0036] Further, the connector 200 is configured in a length-adjustable structure, so that the user can adjust the length of the connector 200 according to the neck or head size, thereby improving the wearing comfort.

[0037] In combination Figure 1 With Figure 2 , the earphone monomer 100 is provided with a first connecting portion 110, and the connector 200 is provided with a second connecting portion 210, and the first connecting portion 110 and the second connecting portion 210 are detachably connected to detachably connect the earphone monomer 100 and the connector 200.

[0038] Specifically, the two earphone monomers 100 are both provided with the first connecting portion 110, and the two ends of the connector 200 are both provided with the second connecting portion 210, the first connecting portion 110 on the left earphone monomer 100 is detachably connected with the second connecting portion 210 at the left end of the connector 200, and the first connecting portion 110 on the right earphone monomer 100 is detachably connected with the second connecting portion 210 at the right end of the connector 200.

[0039] In combination Figure 2 With Figure 3 , the first connecting portion 110 comprises a jack 111 and a plurality of clamping grooves 112 arranged along the circumference of the jack 111 and arranged at intervals on the hole wall of the jack 111.

[0040] Specifically, the earphone monomer 100 comprises an earphone body 100a and an ear hook 100b connected with the earphone body 100a, the first connecting portion 110 is arranged at the end of the ear hook 100b, specifically, the jack 111 is arranged at the end of the ear hook 100b, and the hole wall of the jack 111 is provided with a plurality of clamping grooves 112 arranged along the circumference of the jack 111 and arranged at intervals.

[0041] The second connecting part 210 comprises a plug post 211 and an elastic clamping piece 212 arranged on the plug post 211, at least part of the elastic clamping piece 212 protrudes from the side wall of the plug post 211, and the elastic clamping piece 212 can be compressed to shrink towards the central axis of the plug post 211.

[0042] Specifically, the plug post 211 is arranged at the end of the connector 200, the outer side wall of the plug post 211 is provided with a mounting hole 2111, the elastic clamping piece 212 is arranged in the mounting hole 2111, and at least part of the elastic clamping piece 212 protrudes from the mounting hole 2111 (i.e. protrudes from the side wall of the plug post 211) when the elastic clamping piece 212 is not pressed, and the elastic clamping piece 212 is compressed when the elastic clamping piece 212 is subjected to pressure along the axial direction of the mounting hole 2111. The axis of the mounting hole 2111 is arranged perpendicularly to the central axis of the plug post 211, and of course, the position of the mounting hole 2111 can also have a certain deviation in some other embodiments.

[0043] The plug post 211 is inserted into the plug hole 111, and the plug post 211 is operable relative to the plug hole 111 to rotate to enable the elastic clamping piece 212 to be clamped in any clamping groove 112.

[0044] It should be noted that the groove wall of the clamping groove 112 is arc-shaped, and in the case that the plug post 211 is inserted into the plug hole 111 and the elastic clamping piece 212 is clamped in the clamping groove 112, by rotating the plug post 211 relative to the plug hole 111, the elastic clamping piece 212 can slide along the groove wall of the clamping groove 112, and will be gradually pressed by the groove wall of the clamping groove 112 until it is released from the clamping groove 112, thus, by continuing to rotate the plug post 211 relative to the plug hole 111, the elastic clamping piece 212 can be clamped into another clamping groove 112.

[0045] Further, the side of the elastic clamping piece 212 close to the hole wall of the plug hole 111 is arc-shaped, so that the elastic clamping piece 212 slides in or out of the clamping groove 112 more smoothly.

[0046] Further, the elastic clamping piece 212 comprises an elastic piece and a clamping piece, the elastic piece is arranged in the mounting hole 2111, the clamping piece is arranged opposite to the elastic piece and on the side of the elastic piece away from the central axis of the plug post 211, and the clamping piece is movable along the axial direction of the mounting hole 2111. The elastic piece can be a spring, a spring piece or an elastic rubber, and the end of the clamping piece away from the elastic piece is arc-shaped.

[0047] It can be understood that, since the elastic clamping member 212 can be compressed to shrink towards the central axis of the insertion post 211, before the insertion post 211 is inserted into the insertion hole 111, the elastic clamping member 212 can be compressed in advance to enable the insertion post 211 to be inserted into the insertion hole 111, and then by rotating the earphone unit 100 relative to the connector 200 (i.e. rotating the insertion post 211 relative to the insertion hole 111), the angle of the earphone unit 100 can be adjusted, and in the case that the elastic clamping member 212 is clamped in the clamping groove 112, the risk of the earphone unit 100 being separated from the connector 200 can be reduced. In this way, the user can adjust the angle of the earphone unit 100, thereby improving the comfort of wearing the earphone unit 100. In addition, it should be noted that when it is necessary to detach the earphone unit 100 from the connector 200, a pulling force is applied to the earphone unit 100 and / or the connector 200 to cause the elastic clamping member 212 on the insertion post 211 to be separated from the clamping groove 112, so that the earphone unit 100 and the connector 200 can be separated.

[0048] It should be noted that the plurality of clamping grooves 112 are uniformly and spacedly arranged along the circumference of the insertion hole 111, and the included angle between two adjacent clamping grooves 112 is between 5°-8°, for example, 5°, 6°, 7° or 8°. In this way, the angle of the earphone unit 100 can be adjusted by 5°-8° each time, which can meet the requirement of adjusting the angle of the earphone unit 100.

[0049] In combination Figure 2 With Figure 3 In some embodiments, the bottom wall of the insertion hole 111 is provided with a positioning post 113 coaxially arranged with the insertion hole 111, and the insertion post 211 is provided with a positioning hole 213 coaxially arranged with the insertion post 211, and the positioning post 113 is arranged through the positioning hole 213. In this way, the positioning effect of the insertion post 211 and the insertion hole 111 can be further improved.

[0050] In combination Figure 2 With Figure 4 Further, the positioning post 113 is rotatably sleeved with an elastic sleeve 114, and the elastic sleeve 114 abuts against the hole wall of the positioning hole 213.

[0051] It can be understood that, since the elastic sleeve 114 is sleeved on the positioning post 113 and the elastic sleeve 114 is limited to move along the axial direction of the positioning post 113 relative to the positioning post 113, and the elastic sleeve 114 abuts against the hole wall of the positioning hole 213, the elastic sleeve 114 can apply an elastic force to the insertion post 211, thereby reducing the risk of the insertion post 211 being separated from the insertion hole 111 and causing the earphone unit 100 to be separated from the connector 200.

[0052] It can be understood that the elastic sleeve 114 and the elastic clamping piece 212 can limit the plug 211 from being pulled out of the socket 111, which can greatly reduce the risk of the plug 211 being pulled out of the socket 111. Of course, if it is necessary to disassemble the earphone unit 100 and the connector 200, a greater disassembly force can be applied to the earphone unit 100 and the connector 200.

[0053] The positioning column 113 is sleeved with a bearing 115, and the elastic sleeve 114 is sleeved outside the bearing 115.

[0054] Specifically, the bearing 115 is sleeved on the positioning column 113, and the inner ring of the bearing 115 is fixed with the positioning column 113. The elastic sleeve 114 is sleeved outside the bearing 115, and the elastic sleeve 114 can be spot welded with the bearing 115. In this way, the elastic sleeve 114 can rotate relative to the positioning column 113.

[0055] It should be noted that in the process of rotating the plug 211 relative to the socket 111, the plug 211 will drive the elastic sleeve 114 to rotate together, so as to reduce the risk of wear caused by the relative sliding of the plug 211 relative to the elastic sleeve 114.

[0056] The elastic sleeve 114 can be a metal elastic sleeve, and the cross section of the elastic sleeve 114 is wave-shaped. The elastic sleeve 114 can resist the hole wall of the positioning hole 213. It should be noted that the outer side wall of the end of the elastic sleeve 114 away from the bottom wall of the socket 111 can be chamfered, so that the plug 211 can be more conveniently inserted into the socket 111.

[0057] It should be noted that the structure of the first connecting part 110 and the structure of the second connecting part 210 can also be interchanged, and the interchange of the structure of the first connecting part 110 and the second connecting part 210 can also achieve the effect of angle adjustment of the earphone unit 100.

[0058] In this invention, the user can connect the two earphone units 100 without the connector 200 during normal use. The two earphone units 100 can be worn on the user's left and right ears respectively, making them convenient to use. When the user needs to swim or play ball, or engage in more strenuous activities, the two earphone units 100 can be connected together using the connector 200 to reduce the risk of a single earphone unit 100 falling off and being lost. In addition, since the elastic snap-fit ​​member 212 can be compressed and retract towards the central axis of the plug 211, the elastic snap-fit ​​member 212 can be pre-compressed before the plug 211 is inserted into the socket 111, so that the plug 211 can be inserted into the socket 111. Then, by rotating the earphone unit 100 relative to the connector 200 (that is, rotating the plug 211 relative to the socket 111), the angle of the earphone unit 100 can be adjusted. Furthermore, when the elastic snap-fit ​​member 212 is engaged in the slot 112, the risk of the earphone unit 100 detaching from the connector 200 can be reduced. In this way, users can adjust the angle of the earphone driver 100, thereby improving the wearing comfort of the earphone driver 100 and making it suitable for users with more different head shapes. It should also be noted that when it is necessary to detach the earphone driver 100 from the connector 200, a pulling force is applied to the earphone driver 100 and / or the connector 200 to cause the elastic snap-fit ​​212 on the plug 211 to disengage from the slot 112, thus separating the earphone driver 100 from the connector 200.
