Description

Technical Field

[0001] The present application relates to the field of headphone equipment, and in particular to an ear-hook type bone conduction headphone. Background Art

[0002] Bone conduction is a sound transmission method that converts sound into mechanical vibrations of different frequencies and transmits sound waves through human bones. Compared with the classic sound transmission method that generates sound waves through the diaphragm, bone conduction saves many steps in sound wave transmission and can achieve clear sound restoration in a noisy environment. Moreover, the sound waves will not affect others because they diffuse in the air.

[0003] The relevant technical literature discloses an invention patent with patent number: CN201611237509.7, which relates to the technical field of headphone equipment, and in particular to a bone conduction headphone, comprising: a support frame, a headphone mechanism arranged at both ends of the head support frame, an LED light is arranged on the side of the support frame, a bone conduction microphone is arranged in the headphone mechanism, and a bone conduction speaker connected to the bone conduction microphone, a switch button, function keys and a socket are arranged on the headphone mechanism, and each headphone mechanism is provided with a voice input structure.

[0004] With respect to the above-mentioned related technologies, the inventor believes that when the above-mentioned earphones are used, the volume of the earphones is too large, which is not suitable for occasions where the user needs to exercise more and is not easy to carry. Summary of the invention

[0005] In order to facilitate portability and be suitable for more usage environments, the present application provides an ear-hook bone conduction headset.

[0006] The present application provides an ear-hook bone conduction headset, which adopts the following technical solution:

[0007] An ear-hook bone conduction headset comprises a main body, a bending arm with an arc opening facing the main body is arranged on the upper side of the main body, one end of the bending arm is rotatably connected to one side of the main body, and a bone conduction vibrator is arranged on the other end of the bending arm, and a rotating structure is arranged between the main body and the bending arm, which can drive the bending arm to rotate to the top of the main body under normal conditions.

[0008] By adopting the above technical solution, when using, the earphone is placed in the auricle, and then the bending arm is swung so that the bending arm drives the bone conduction vibrator to rotate to the outside of the auricle, and then the bending arm is released, and the bending arm can be driven to rotate by the torsion spring, so that the bending arm drives the bone conduction vibrator to fit the outside of the auricle, thereby realizing the use of the earphone, which is small in size, easy to carry and simple to operate.

[0009] Optionally, the bending arm includes a fixed arm connected to the connecting column and a movable arm connected to the bone conduction vibrator, and a torsion structure is arranged between the movable arm and the fixed arm.

[0010] By adopting the above technical solution and the torsion structure, the movable arm and the fixed arm can be rotated, so that the distance between the movable arm and the main body can be adjusted to meet different usage requirements.

[0011] Optionally, a connecting sleeve is provided on one side of the main body, and a rotating column coaxially arranged with the connecting sleeve is rotatably connected inside the connecting sleeve, and one end of the bending arm away from the bone conduction vibrator is connected to the connecting column and can rotate with the connecting column, and the rotating structure includes a torsion spring 1 which is sleeved on the rotating column, and one end of the torsion spring 1 is fixedly connected to the rotating column and the other end of the torsion spring is fixedly connected to the connecting sleeve.

[0012] By adopting the above technical solution, the rotating column and the connecting sleeve cooperate with each other, so that the bending arm can be rotated relative to the main body. The torsion spring can keep the bending arm directly above the main body under normal conditions, thereby clamping the user's ears.

[0013] Optionally, a sliding column is vertically slidably connected in the rotating column and is arranged coaxially with the rotating column, and the lower end of the sliding column is hinged with a clamping column that can protrude from the circumference of the rotating column as the sliding column moves downward; a connecting column is fixedly connected to one end of the bending arm close to the rotating column, and the side of the connecting column away from the main body is hinged with the side of the rotating column away from the main body, and the rotation axis of the connecting column and the rotating column is perpendicular to the axis of the rotating column, and a torsion spring three is arranged between the connecting column and the rotating column under normal circumstances; the upper end of the sliding column is slidably connected to the connecting column, and the bending arm rotates in the direction away from the rotating column to drag the sliding column upward, and a clamping protrusion is arranged in the connecting sleeve that can prevent the clamping column from rotating with the rotating column.

[0014] By adopting the above technical solution, when in use, the bending arm is bent in the direction away from the axis of the rotating column, which can drive the sliding column to slide upward, and then drive the lower end of the clamping column to retract into the rotating column, and then the bending arm is rotated in the direction away from the main body, which can drive the bending arm to rotate to one side of the main body, and also make the clamping column pass the clamping convex position. At this time, the bending arm is released, and the bending arm is reset by the action of torsion spring three, so that the connecting column abuts against the rotating column, and the sliding column will also move downward through the push of the connecting column, so that the clamping column protrudes out of the outside of the rotating column. In addition, the torsion spring one will drive the rotating column to rotate, so that the clamping column abuts against the clamping convex However, since the card post passes the bulge, the torsion spring one can drive the rotating column to reset, thereby causing the bending arm to rotate toward the main body, so that the bone conduction vibrator at the other end of the bending arm is closely in contact with the outer side of the auricle.

[0015] Optionally, the lower end of the connecting sleeve is rotatably connected to a chassis, the latch is vertically fixed to an upper side of the chassis, and a positioning structure capable of fixing a relative position of the chassis and the connecting sleeve is provided between the connecting sleeve and the chassis.

[0016] By adopting the above technical solution, when using, the chassis can be rotated according to the needs of use, thereby driving the clamping convex to rotate and adjust the position of the clamping convex. On the one hand, the angle between the bending arm and the main body can be limited by the clamping convex, which is convenient for the user to wear it on the ear, and then the bending arm is bent to make the clamping column pass over the clamping convex, and the bending arm is driven to reset to the bone conduction vibrator to abut the auricle through the action of the torsion spring, which is convenient for wearing. On the other hand, after wearing the earphone, the force of the torsion spring is too large, resulting in a large clamping force between the bending arm and the main body, which causes the user's ear to be severely clamped. , the chassis can be rotated to drive the clamping convex, and the position of the clamping column can be limited by the clamping convex, thereby limiting the angle between the main body and the bending arm after wearing, ensuring the comfort of the user's ears and avoiding pinching the ears. Thirdly, when the user needs to move more after wearing, the chassis can be rotated to drive the clamping convex to abut against the side of the clamping column that can rotate to increase the angle between the bending arm and the main body, thereby limiting the maximum rotation angle between the main body and the bending arm, so that the main convex part and the bending arm firmly clamp the user's ears to avoid the earphones falling off during the user's exercise.

[0017] Optionally, the positioning structure includes a gear ring fixed to the lower end of the connecting sleeve and arranged coaxially with the rotating column, a gear groove in which the gear ring can be inserted is opened on the upper side of the chassis, a slip ring inserted in the lower end of the rotating column is rotatably connected to the upper middle part of the chassis, and a tension spring is arranged between the slip ring and the rotating column which can pull the chassis to move upward under normal conditions.

[0018] By adopting the above technical solution, when in use, the chassis can be pulled downward to disengage the toothed ring and the toothed groove from each other, so that the chassis can be conveniently rotated. After the rotation of the chassis is realized, the chassis is released and the chassis is driven to move upward by the tension spring, so that the toothed ring is inserted into the toothed groove to realize the relative positioning of the chassis and the connecting sleeve.

[0019] Optionally, a marking needle is provided on the circumferential surface of the lower end of the connecting sleeve, and a scale plate is fixedly connected to the circumferential surface of the chassis.

[0020] By adopting the above technical solution, the scale plate and the marking needle cooperate with each other, which can facilitate the user to observe the rotation angle of the chassis, thereby determining the position of the clamping protrusion, which is convenient for the user to observe.

[0021] Optionally, a limiting groove is provided on the lower bottom surface of the connecting column, the length direction of the limiting groove is perpendicular to the rotation axis direction of the connecting column and the rotating column, and the upper end of the sliding column is fixedly connected to a movable shaft slidably connected to the limiting groove.

[0022] By adopting the above technical solution, the limiting groove and the movable shaft cooperate with each other, so that the connecting column can rotate to drive the movable shaft to slide along the limiting groove and drag the sliding column to move upward.

[0023] Optionally, a side of the connecting sleeve close to the main body is connected to the main body in a damping rotation manner.

[0024] By adopting the above technical solution, the main body and the connecting sleeve can be rotated according to the needs of the user, so as to adjust the angle between the main body and the connecting sleeve, meet the different usage needs of the user, and improve the comfort of the ear.

[0025] Optionally, the main body is disc-shaped, and the axis of the main body is perpendicular to the axis of the connecting sleeve. A surface of the main body that can abut against the auricle is provided with a flexible sleeve, and the bending arm is provided with a soft sleeve.

[0026] By adopting the above technical solution, the flexible cover and the soft cover can prevent the main body and the bending arm from pinching the ears, thereby protecting the user.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When using, place the earphone in the auricle, then swing the bending arm to make the bending arm drive the bone conduction vibrator to rotate to the outside of the auricle, then loosen the bending arm, and the bending arm can be driven to rotate by the torsion spring, so that the bending arm drives the bone conduction vibrator to fit the outside of the auricle, thereby realizing the use of the earphone, which is small in size, easy to carry and simple to operate;

[0029] 2. When in use, the bending arm is bent in the direction away from the axis of the rotating column, so that the sliding column can be driven to slide upward, and then the lower end of the clamping column can be driven to retract into the rotating column. Then, the bending arm is rotated in the direction away from the main body, which can drive the bending arm to rotate to one side of the main body, and also make the clamping column pass the clamping convex position. At this time, the bending arm is released, and the bending arm is reset by the action of the torsion spring three, so that the connecting column abuts against the rotating column, and the sliding column will also move downward through the push of the connecting column, so that the clamping column protrudes out of the outside of the rotating column. In addition, the torsion spring one will drive the rotating column to rotate, so that the clamping column abuts against the clamping convex, realizing the rotation. The limit position of the movable column at this time ensures that it is convenient for the user to put the earphone on the earphone. After putting the earphone on the earphone, the bending arm is bent again to rotate in the direction away from the axis of the rotating column, driving the sliding column to move upward, so that the clamping column is retracted into the rotating column, and then the bending arm is rotated in the direction of the main body so that the clamping column passes over the clamping convexity, and then the hand is released, and the torsion spring three drives the connecting column to reset, and the clamping column will protrude from the rotating column again. However, because the clamping column passes over the clamping convexity, the torsion spring one can drive the rotating column to reset, so that the bending arm rotates in the direction of the main body, so that the bone conduction vibrator at the other end of the bending arm is closely abutted against the outer side of the auricle;

[0030] 3. When in use, the chassis can be rotated according to the needs of use, thereby driving the clamping convex to rotate and adjust the position of the clamping convex. On the one hand, the angle between the bending arm and the main body can be limited by the clamping convex, which is convenient for the user to wear it on the ear, and then the bending arm can be bent to make the clamping column pass over the clamping convex, and the bending arm can be reset to the bone conduction vibrator abutting the auricle through the action of the torsion spring, which is convenient for wearing. On the second hand, after wearing the earphone, the torsion spring has too large a force, resulting in a large clamping force between the bending arm and the main body, which causes the user's ear to be severely clamped. The clamping convex can be driven by rotating the chassis to limit the position of the clamping column through the clamping convex, thereby limiting the angle between the main body and the bending arm after wearing, ensuring the comfort of the user's ear and avoiding pinching the ear. On the third hand, when the user needs to move more after wearing, the chassis can be rotated to drive the clamping convex to abut on the side of the clamping column that can rotate to increase the angle between the bending arm and the main body, thereby limiting the maximum rotation angle between the main body and the bending arm, so that the main convex part and the bending arm firmly clamp the user's ear, and prevent the earphone from falling off during the user's movement.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-9 This application is described in further detail.

[0042] The embodiment of the present application discloses an ear-hook type bone conduction headset.

[0043] Example 1

[0044] Reference Figure 1 , an ear-hook bone conduction headset, comprising a main body 1, a bending arm 2 and a bone conduction vibrator 3.

[0045] Reference Figure 1 and Figure 2 The main body 1 is disc-shaped, and the axis of the main body 1 is arranged horizontally. A flexible sleeve is connected to one surface of the main body 1, and a connecting sleeve 4 is vertically arranged on one side of the main body 1, and one side of the connecting sleeve 4 is fixedly connected to one side of the main body 1. The bending arm 2 is arranged on the upper side of the main body 1, and the bending arm 2 is arranged in a C-shaped shape with the arc opening facing downward. One end of the bending arm 2 extends into the connecting sleeve 4 and is fixedly connected to a rotating column 5. The rotating column 5 is rotatably connected to the connecting sleeve 4, and the axes of the rotating column 5 and the connecting sleeve 4 are in the same position. Through the rotating column 5, the bending arm 2 can be rotated toward a surface of the main body 1 provided with the flexible sleeve. The angle at which the bending arm 2 can rotate relative to the main body 1 is preferably 25° but not limited to 25°.

[0046] Reference Figure 1 and Figure 2 A rotating structure is provided between the rotating column 5 and the connecting sleeve 4 to realize the rotational positioning of the rotating column 5 and the connecting sleeve 4. The rotating structure can adopt damping rotation or a torsion spring. This embodiment takes a torsion spring as an example of the rotating structure.

[0047] The rotating structure includes a torsion spring 51 sleeved on the rotating column 5, one end of the torsion spring 51 is fixedly connected to the rotating column 5, and the other end of the torsion spring 51 is fixedly connected to the connecting sleeve 4. Under normal conditions, the torsion spring 51 can drive the rotating column 5 to rotate and reset, so that the bending arm 2 can be located on the upper side of the main body 1. The upper sleeve of the bending arm 2 is provided with a soft sleeve, and the bone conduction vibrator 3 is fixedly connected to the end of the bending arm 2 away from the rotating column 5.

[0048] The implementation principle of Example 1 is as follows: when in use, place the earphone in the auricle, then swing the bending arm 2 so that the bending arm 2 drives the bone conduction vibrator 3 to rotate to the outside of the auricle, and then release the bending arm 2, so that the bending arm 2 can be driven to rotate by the torsion spring 51, so that the bending arm 2 drives the bone conduction vibrator 3 to fit the outside of the auricle, thereby realizing the use of the earphone, which is small in size, easy to carry, and simple to operate.

[0049] Example 2: Reference Figure 3 and Figure 4, an ear-hook bone conduction headset, which differs from the first embodiment in that: the bending arm 2 includes a fixed arm 21 connected to the connecting column 23 and a movable arm 22 connected to the bone conduction vibrator 3, the ends of the movable arm 22 and the fixed arm 21 close to each other are hinged to each other, the rotation axis of the movable arm 22 and the fixed arm 21 is in the same direction as the axis of the main body 1, the end of the movable arm 22 close to the fixed arm 21 is fixedly connected with a hinge shaft 221, the end of the fixed arm 21 close to the movable arm 22 is provided with a hinge hole 211, the hinge shaft 221 is inserted into the hinge hole 211 and hinged in the hinge hole 211, thereby realizing the mutual hinge between the movable arm 22 and the fixed arm 21, and the rotation angle of the movable arm 22 relative to the fixed arm 21 is preferably 45° but not limited to 45°.

[0050] Reference Figure 4 A torsion structure is provided between the movable arm 22 and the fixed arm 21 to enable the movable arm 22 and the fixed arm 21 to be rotated and fixed. The torsion structure may adopt a damped rotation or a torsion spring. In this embodiment, a torsion spring is used as an example of the torsion structure.

[0051] Reference Figure 4 The torsion structure includes a torsion spring 222 sleeved on the hinge shaft 221, one end of the torsion spring 222 is fixed to the movable arm 22, and the other end is fixed to the movable arm 22. Under normal conditions, the torsion spring 222 can drive the movable arm 22 to rotate toward the main body 1 until the bone conduction vibrator 3 abuts against the main body 1.

[0052] Compared with the first embodiment, the present embodiment has the advantages that the torsion structure adopted can realize the rotation of the movable arm 22 and the fixed arm 21, so that the distance between the movable arm 22 and the main body 1 can be adjusted to meet different usage requirements.

[0053] Example 3

[0054] Reference Figure 5 , an ear-hook bone conduction headset, comprising a main body 1, a bending arm 2 and a bone conduction vibrator 3.

[0055] Reference Figure 5 The main body 1 is disc-shaped, and the axis of the main body 1 is horizontally arranged. A flexible sleeve is connected to one surface of the main body 1, and a connecting sleeve 4 is vertically arranged on one side of the main body 1. One side of the connecting sleeve 4 is rotatably connected to one side of the main body 1. The connecting sleeve 4 and the main body 1 have a rotation axis that is horizontally arranged and perpendicular to the axis of the main body 1. The rotation connection between the connecting sleeve 4 and the main body 1 adopts a damping rotation connection.

[0056] Reference Figure 5 and Figure 6The bending arm 2 is arranged above the main body 1, and the bending arm 2 is in a C-shaped shape with the arc opening facing downward. A soft sleeve is sleeved on the bending arm 2. A connecting column 23 with an axis vertically arranged is fixedly connected to one end of the bending arm 2 close to the connecting sleeve 4, and a bone conduction vibrator 3 is fixedly connected to the other end of the bending arm 2. A rotating column 5 with the same axis direction as the connecting sleeve 4 is rotatably connected. The connecting column 23 is coaxially arranged with the rotating column 5. The lower end of the connecting column 23 is connected to the rotating column 5, and the connecting column 23 can rotate synchronously with the rotating column 5. A torsion spring 51 is sleeved on the rotating column 5. One end of the torsion spring 51 is fixedly connected to the rotating column 5, and the other end of the torsion spring 51 is fixedly connected to the connecting sleeve 4. When in use, the bending arm 2 can be rotated toward one side of the flexible sleeve of the main body 1 through the rotating column 5, and when the bending arm 2 loses external force, the torsion spring 51 can drive the rotating column 5 to automatically rotate and reset, so that the bending arm 2 is rotated again to the top of the main body 1.

[0057] Reference Figure 6 and Figure 7 When in use, place the earphone in the auricle, then swing the bending arm 2 so that the bending arm 2 drives the bone conduction vibrator 3 to rotate to the outside of the auricle, and then release the bending arm 2, so that the bending arm 2 can be driven to rotate through the torsion spring 51, so that the bending arm 2 drives the bone conduction vibrator 3 to fit the outside of the auricle, thereby realizing the use of the earphone.

[0058] Reference Figure 6 and Figure 7 The side of the lower end of the connecting column 23 away from the main body 1 and the side of the upper end of the rotating column 5 away from the main body 1 are hinged to each other, and the connecting column 23 and the rotating axis of the rotating column 5 are horizontally arranged, so that the connecting column 23 can be bent in the direction away from the axis of the rotating column 5, thereby making the axes of the connecting column 23 and the rotating column 5 inclined to each other. A vertical slot 52 is vertically provided in the rotating column 5, and a sliding column 53 is vertically slidably connected in the vertical slot 52. A transverse slot 54 extending out of the circumference of the rotating column 5 is horizontally provided at the lower end of the rotating column 5 corresponding to the vertical slot 52, and a clamping column 55 is slidably connected in the transverse slot 54. One end of the clamping column 55 close to the vertical slot 52 is hinged to the sliding column 53, and the upper top surface of the transverse slot 54 is an inclined surface inclined downwardly arranged from one end of the vertical slot 52 to the end away from the vertical slot 52, so that when the sliding column 53 slides upward in the vertical direction, the clamping column 55 can be driven to rotate to an inclined state with the sliding column 53 and shrink into the transverse slot 54; when the sliding column 53 slides downward in the vertical direction until it abuts against the bottom surface of the vertical slot 52, it can drive the clamping column 55 to rotate to a horizontal state with the sliding column 53 and extend out of the transverse slot 54 and protrude out of the circumference of the rotating column 5.

[0059] Reference Figure 6 and Figure 8A limiting groove 24 is provided on the lower end surface of the connecting column 23, and the length direction of the limiting groove 24 is perpendicular to the rotation axis direction of the connecting column 23 and the rotating column 5. The cross-section of the limiting groove 24 is T-shaped. The upper end of the sliding column 53 extends out of the upper end of the rotating column 5 and is rotatably connected with a movable shaft 531. The axial direction of the movable shaft 531 is perpendicular to the length direction of the limiting groove 24, and the movable shaft 531 can slide along the length direction of the limiting groove 24.

[0060] Reference Figure 6 and Figure 7 A chassis 6 is provided at the lower end of the connecting sleeve 4, and the axis of the chassis 6 is in the same straight line as the axis of the connecting sleeve 4. The upper side of the chassis 6 is fixed to a protrusion 61 vertically extending into the connecting sleeve 4. The protrusion 61 can block the column 55, thereby limiting the rotation of the rotating column 5.

[0061] Reference Figure 6 and Figure 7 When in use, the bending arm 2 is bent in the direction away from the axis of the rotating column 5, which can drive the sliding column 53 to slide upward, and then drive the lower end of the clamping column 55 to retract into the rotating column 5, and then the bending arm 2 is rotated in the direction away from the main body, which can drive the bending arm 2 to rotate to one side of the main body 1, and at the same time make the clamping column 55 pass the position of the clamping protrusion 61. At this time, the bending arm 2 is released, and the bending arm 2 is reset by the action of the torsion spring 3 231, so that the connecting column 23 abuts against the rotating column 5, and the sliding column 53 will also move downward through the push of the connecting column 23, so that the clamping column 55 protrudes out of the outside of the rotating column 5. In addition, the torsion spring 1 51 will drive the rotating column 5 to rotate, so that the clamping column 55 abuts against the clamping protrusion 61, realizing The limit of the rotating column 5 at this time ensures that it is easy for the user to put the earphones on the earphones. After the earphones are put on, the bending arm 2 is bent again to rotate in the direction away from the axis of the rotating column 5, driving the sliding column 53 to move upward, so that the clamping column 55 is retracted into the rotating column 5, and then, the bending arm 2 is rotated in the direction of the main body 1 to make the clamping column 55 pass over the clamping protrusion 61, and then the hand is released, and the torsion spring three 231 drives the connecting column 23 to reset, and the clamping column 55 will protrude from the rotating column 5 again. However, since the clamping column 55 passes over the clamping protrusion 61, the torsion spring one 51 can drive the rotating column 5 to reset, so that the bending arm 2 rotates in the direction of the main body 1, so that the bone conduction vibrator 3 at the other end of the bending arm 2 is closely abutted against the outer side of the auricle.

[0062] Reference Figure 7 and Fig. 9The upper side of the chassis 6 is rotatably connected with a slip ring 62 inserted in the lower end of the connecting sleeve 4 at the axial position. A tension spring 63 is vertically arranged in the slip ring 62. The upper end of the tension spring 63 is fixed to the rotating column 5, and the lower end of the tension spring 63 is fixed to the slip ring 62. Under normal conditions, the tension spring 63 can drag the slip ring 62 to move upward, so that the upper side of the chassis 6 abuts against the lower end surface of the connecting sleeve 4. A positioning structure capable of fixing the relative position of the chassis 6 and the connecting sleeve 4 is also arranged between the connecting sleeve 4 and the chassis 6. The positioning structure includes a toothed ring 41 fixed to the lower end of the connecting sleeve 4 and arranged coaxially with the rotating column 5. A toothed groove 64 is opened on the upper side of the chassis 6 corresponding to the position of the toothed ring 41. When the chassis 6 abuts against the connecting sleeve 4, the toothed ring 41 can be inserted into the toothed groove 64 to realize the positioning of the chassis 6 relative to the connecting sleeve 4. When the chassis 6 is pulled down until the tooth is disengaged from the toothed groove 64, the chassis 6 can be rotated, thereby adjusting the position of the clamping protrusion 61 in the connecting sleeve 4.

[0063] Reference Figure 7 and Fig. 9 When in use, the chassis 6 can be rotated according to the needs of use, thereby driving the clamping protrusion 61 to rotate and adjust the position of the clamping protrusion 61. On the one hand, the clamping protrusion 61 can limit the angle between the bending arm 2 and the main body 1, which is convenient for the user to wear it on the ear, and then the bending arm 2 is bent to make the clamping column 55 pass over the clamping protrusion 61, and the bending arm 2 is driven to reset to the bone conduction vibrator 3 to abut the auricle through the torsion spring 1 51, which is convenient for wearing. On the other hand, after wearing the earphone, the force of the torsion spring 1 51 is too large, resulting in a large clamping force between the bending arm 2 and the main body 1, which causes the user's ear to be severely clamped. By rotating the chassis 6 to drive the locking protrusion 61, the position of the locking column 55 is limited by the locking protrusion 61, thereby limiting the angle between the main body 1 and the bending arm 2 after wearing, ensuring the comfort of the user's ears and avoiding pinching the ears. Thirdly, when the user needs to move more after wearing, the chassis 6 can be rotated to drive the locking protrusion 61 to abut against the side of the locking column 55 that can rotate to increase the angle between the bending arm 2 and the main body 1, thereby limiting the maximum rotation angle between the main body 1 and the bending arm 2, so that the main protrusion and the bending arm 2 firmly clamp the user's ears to avoid the earphones falling off during the user's movement.

[0064] Reference Figure 7 and Fig. 9 The lower end circumference of the connecting sleeve 4 is provided with a marking needle 42, and the circumference of the chassis 6 is fixed with a scale plate 65. The scale plate 65 cooperates with the marking needle 42 to facilitate the user to observe the rotation angle of the chassis 6, thereby determining the position of the convex 61, which is convenient for the user to observe.

[0065] The implementation principle of Example 3 is as follows: when using, place the earphone in the auricle, then swing the bending arm 2 so that the bending arm 2 drives the bone conduction vibrator 3 to rotate to the outside of the auricle, then loosen the bending arm 2, and the bending arm 2 can be driven to rotate by the torsion spring 1 51, so that the bending arm 2 drives the bone conduction vibrator 3 to fit the outside of the auricle, and then the earphone can be used;

[0066] In addition, the chassis 6 can be rotated according to the needs of use, thereby driving the locking protrusion 61 to rotate and adjust the position of the locking protrusion 61. On the one hand, the locking protrusion 61 can limit the angle between the bending arm 2 and the main body 1, so that the user can wear it on the ear, and then the bending arm 2 can be bent to make the clamping column 55 pass over the clamping protrusion 61, and the bending arm 2 can be driven to reset to the bone conduction vibrator 3 to abut the auricle through the torsion spring 1 51, so that it is convenient to wear. On the other hand, after wearing the earphone, the torsion spring 1 51 has too large a force, resulting in a large clamping force between the bending arm 2 and the main body 1, which causes the user's ear to be severely clamped. By rotating the chassis 6 to drive the locking protrusion 61, the position of the locking column 55 is limited by the locking protrusion 61, thereby limiting the angle between the main body 1 and the bending arm 2 after wearing, ensuring the comfort of the user's ears and avoiding pinching the ears. Thirdly, when the user needs to move more after wearing, the chassis 6 can be rotated to drive the locking protrusion 61 to abut against the side of the locking column 55 that can rotate to increase the angle between the bending arm 2 and the main body 1, thereby limiting the maximum rotation angle between the main body 1 and the bending arm 2, so that the main protrusion and the bending arm 2 firmly clamp the user's ears to avoid the earphones falling off during the user's movement.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
