[0031] In the prior art, a limit spring piece is generally provided on the plug-in column to mesh with the internal gear mouth for damping adjustment. When the microphone rod 3 is rotated, the limit spring piece meshes with the internal gear mouth to achieve damping adjustment. However, such a structure is generally more complicated and the production cost is higher.

[0032] See also Figures 1 to 4 The utility model provides an earphone, comprising a shell 1, a fastener 2 and a microphone rod 3, wherein the shell 1 is formed with a connecting shaft 11, the shell 1 is formed with a first connecting hole 12, the connecting shaft 11 is formed with a second connecting hole 111, and the first connecting hole 12 and the second connecting hole 111 are connected to each other; a lubricating layer is formed on the outer surface of the fastener 2; the microphone rod 3 comprises a shell 31 and a damping member 32; the shell 31 is formed with an inner cavity, the inner cavity comprises a first cavity 311 and a second cavity 312 which are connected to each other, the first cavity 311 is formed with a first convex column 311a, the first convex column 311a is formed with a third connecting hole 311b, the damping member 32 is arranged on the bottom surface of the first cavity 311, and the damper can be directly adhered to the bottom surface of the first cavity 311, the connecting shaft 11 extends into the first cavity 311, the fastener 2 sequentially passes through the first connecting hole 12 and the second connecting hole 111 and is installed in the third connecting hole 311b, so that the connecting shaft 11 is tightly pressed against the damping member 32. Specifically, after assembly, the connecting shaft 11 is a fixed part. When the user turns the microphone rod 3, the microphone rod 3, the damping member 32 and the fastener 2 are relatively stationary and rotate around the central axis of the connecting shaft 11. The fastener 2 will give a positive pressure to the damping member 32 by locking the connecting shaft 11 and the microphone rod 3. During the rotation process, this positive pressure will be converted into the sliding friction force of the connecting shaft 11 and the damping member 32, thereby forming a damping feeling when the microphone rod 3 is rotated, so as to achieve damping adjustment. And the size of the damping value can be achieved by changing the locking force of the fastener 2, the thickness of the damping member 32 and the sliding friction coefficient. The technical solution of this embodiment only needs to lock the connecting shaft 11 and the microphone rod 3 through the locking member 5, so that the connecting shaft 11 and the damping member 32 are abutted. When the microphone rod 3 rotates, a damping feeling will be generated between the connecting shaft 11 and the damping member 32, thereby achieving damping adjustment, which greatly simplifies the structure of the microphone rod 3 and greatly reduces the production cost of the microphone rod 3.

[0033] Furthermore, after rotating the microphone rod 3 for many times, friction will be generated on the contact surface between the fastener 2 and the connecting shaft 11, which may cause the fastener 2 to become loose and reduce the damping feeling due to the friction. The contact surface between the connecting shaft 11 and the fastener 2 is lubricated to minimize the friction on the contact surface. This can reduce the damping feeling of the Mogan during long-term rotation and extend its service life.

[0034] In one embodiment, the damping member 32 is an annular damping member 32, and the damping member 32 is sleeved on the first protrusion 311a. The damping member 32 is set as an annular damping member 32, so that the microphone lever 3 can achieve damping adjustment during the 360° rotation process, thereby improving the user's comfort.

[0035] See also Figures 1 to 4 In one embodiment, the microphone rod 3 further includes an elastic member 33. A groove 112 is formed on the side of the connecting shaft 11 away from the housing 1. The elastic member 33 is formed with a through hole. The elastic member 33 is sleeved on the first convex column 311a. The side wall of the elastic member 33 is tightly pressed against the side wall of the groove 112. When the user moves the microphone rod 3, the microphone rod 3, the damping member 32, the elastic body and the fastener 2 are relatively stationary and rotate around the central axis of the connecting shaft 11. During the rotation, a sliding friction force is generated between the connecting shaft 11 and the damping member 32, thereby forming a damping feeling when the microphone rod 3 is rotated. There is a certain amount of interference between the elastic body and the side of the groove 112, that is, the elastic member 33 is compressed. When rotating, the compression force generated by the elastic member 33 can be converted into a sliding friction force to provide a part of the damping feeling for the microphone rod 3. Under the joint action of the above two, the microphone rod 3 can have a certain damping feeling to ensure that it does not fall off at will when it is moved and obtain a better user experience.

[0036] Furthermore, the elastic member 33 can make the microphone rod 3 maintain the rotation damping feeling after being stored in a high temperature and high humidity environment for a period of time. After being stored in a high temperature and high humidity environment, the locking force of the fastener 2 will be weakened to a certain extent, so the damping feeling will be weakened, but because the elastic member 33 still has a certain amount of compression to give the connecting shaft 11 sliding friction, the damping feeling will only be reduced by a small part, and will not disappear completely. At this time, there is still a certain damping value to ensure that the microphone rod 3 does not fall off at will when it is turned.

[0037] See also Figures 1 to 4 In one embodiment, a clamping member 311c is formed on the outer surface of the first protrusion 311a along the length direction of the first protrusion 311a, and the elastic member 33 is formed with a clamping groove 331 that is interconnected with the through hole, and the clamping member 311c is clamped in the clamping groove 331. By providing the clamping groove 331 and the clamping member 311c, the clamping member 311c is clamped in the clamping groove 331, so that the elastic member 33 can be prevented from rotating and falling.

[0038] See also Figures 1 to 4In one embodiment, there are multiple clamping members 311c, which are spaced apart around the central axis of the first convex column 311a, and there are multiple clamping grooves 331, which are spaced apart around the central axis of the through hole. The number of the multiple clamping members 311c is equal to the number of the multiple clamping grooves 331 and they are arranged one by one. By providing multiple clamping members 311c and clamping grooves 331, the elastic member 33 can be further prevented from rotating and falling.

[0039] See also Figures 1 to 4 In one embodiment, the microphone rod 3 further includes a cover plate 4 and a locking member 5. A sound pickup component 41 is provided on the cover plate 4. The cover plate 4 is formed with a first locking hole 42. The second cavity 312 is formed with a second convex column 312a. The second convex column 312a is formed with a second locking hole 312b. The locking member 5 passes through the first locking hole 42 and is installed in the second locking hole 312b, so that the cover plate 4 covers the second cavity 312. The sound pickup component 41 includes but is not limited to a microphone and a dustproof net. By providing the sound pickup component 41, the sound emitted by the user can be converted into an electrical signal and transmitted to the device of the person who is talking. The cover plate 4 is provided to cover the second cavity 312, so that the safety of the components in the second cavity 312 can be protected. The use of the locking member 5 can realize the rapid disassembly and installation of the cover plate 4.

[0040] See also Figures 1 to 4In one embodiment, the cover plate 4 is provided with a first protrusion 43, the first protrusion 43 extends to the first cavity 311, a second protrusion 311d is formed inside the first cavity 311, the outer surface of the connecting shaft 11 is formed with a slide groove 113 arranged in an annular shape around the central axis of the connecting shaft 11, the number of the slide grooves 113 is two, the two slide grooves 113 are arranged at intervals along the length direction of the central axis of the connecting shaft 11, the first protrusion 43 is slidably mounted in one slide groove 113, the second protrusion 311d is slidably mounted in the other slide groove 113, the housing 1 also includes two limit blocks 34, the two limit blocks 34 are respectively mounted in the two slide grooves 113, one limit block 34 is used to abut against the first protrusion 43, and the other limit block 34 is used to abut against the second protrusion 311d. In the prior art, a limit mechanism is provided to prevent the user from excessively rotating the microphone rod 3 to deviate from the vicinity of the mouth, resulting in a poor sound pickup effect. In this embodiment, the first protrusion 43 is slidably installed in the upper slide groove 113, and the second protrusion is slidably installed in the lower slide groove 113. When the microphone rod 3 rotates, the first protrusion 43 and the second protrusion will rotate in the two slide grooves 113 respectively. When the first protrusion 43 abuts against a limit block 34, the second protrusion will also abut against another limit block 34, so that the limit effect is achieved. The limit blocks 34 are installed at different positions of the slide groove 113, so that the rotation angle of the microphone rod 3 can be changed. Generally speaking, the microphone rod 3 can achieve a large-angle rotation in both positive and negative directions, that is, a rotation of 180° to 270°, so that the left and right ears can be worn interchangeably to meet the wearing needs of different users. At the same time, the double limit blocks 34 are set, and the limit strength is greatly improved, so that the microphone rod 3 will not fail due to the instantaneous force or normal force generated by the user's sudden and strong bending when it rotates to the limit position; and the use of two limit blocks 34 to work together can improve the limit strength.

[0041] See also Figures 1 to 4 In one embodiment, the earphone further comprises a cable, and the housing 1 is formed with a cable hole 313, the cable hole 313 is interconnected with the first cavity 311, one end of the cable is connected to the sound pickup component 41, and the other end of the cable passes through the cable hole 313 and extends into the housing 1. By providing the cable hole 313, the cable can be connected from the first cavity 311 to the housing 1, so that the cable can be arranged inside, which can protect the cable from being damaged; the annular space formed between the connecting shaft 11, the microphone rod 3, the damping member 32, and the elastic member 33 allows the cable to have a relatively abundant cable hiding space when rotating, which can avoid the phenomenon that the cable does not communicate due to frequent jamming when the microphone rod 3 rotates.

[0042] See also Figures 1 to 4In one embodiment, a plurality of card plates 312c are formed in the first cavity 311 and are arranged at intervals along the length direction of the microphone rod 3. Each card plate 312c is provided with a card slot 312d, and the cable is connected to the card slot 312d. By providing the card slot 312d, the cable can be fixed, the arrangement is neat, and subsequent maintenance is convenient.
