DETAILED DESCRIPTION

[0024] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0025] See Figures 1-3 and Figure 5 As shown, a bone conduction headphone with adjustable clamping force includes a housing 1, a bone conduction vibrator 11 installed inside the housing 1, and a flexible ear clip 12 fixedly connected to one end of the housing 1. The headphone is characterized by further comprising an adjustment mechanism and a support mechanism. The adjustment mechanism is disposed within the housing 1 and is used to drive the flexible ear clip 12 to deform and adjust the clamping force on the ear bone, while maintaining a constant clamping force. The support mechanism is disposed within the flexible ear clip 12 and is used to support the flexible ear clip 12 to deform in accordance with the operation of the adjustment mechanism. The joint mechanism includes a self-locking mechanism and a transmission mechanism. The self-locking mechanism is located inside the housing 1 and is used to maintain the deformed state of the flexible ear clip 12. The transmission mechanism is located inside the housing 1 and is used to drive the flexible ear clip 12 to rotate and deform. The self-locking mechanism includes a knob 2, a worm 21, and a worm wheel 22. The knob 2 is rotatably located on the outside of the housing 1. The worm 21 is rotatably located inside the housing 1, and one end of the worm 21 is connected to the knob 2. The worm wheel 22 is rotatably located inside the housing 1 and meshes with the worm 21.

[0026] The transmission mechanism includes a first synchronous pulley 23, a synchronous belt 24, and a second synchronous pulley 25. The first synchronous pulley 23 is rotatably disposed inside the housing 1 and is connected to a worm gear 22. The synchronous belt 24 is sleeved on the first synchronous pulley 23. The second synchronous pulley 25 is rotatably disposed inside the housing 1 and meshes with the end of the synchronous belt 24 away from the first synchronous pulley 23. The support mechanism includes a support plate 26 and a connecting plate 27. The support plate 26 is embedded in the side of the flexible ear clip 12 near the bone conduction vibrator 11. One end of the connecting plate 27 is connected to the support plate 26, and the other end of the connecting plate 27 is fixedly connected between the two second synchronous pulleys 25.

[0027] The flexible ear clip 12 has a shape memory alloy sheet inside, one end of which is connected to the outer shell 1, and the outer side of the shape memory alloy sheet is wrapped with silicone.

[0028] Specifically, when the bone conduction headphones are in use, rotating knob 2 causes the worm gear 21 to rotate. Since the worm gear 21 meshes with the worm wheel 22, the worm wheel 22 rotates accordingly, which in turn drives the first synchronous pulley 23 to rotate. Both the first synchronous pulley 23 and the second synchronous pulley 25 mesh with the synchronous belt 24. The first synchronous pulley 23 drives the second synchronous pulley 25 to rotate via the synchronous belt 24. The second synchronous pulley 25 drives the connecting plate 27 to rotate, and the connecting plate 27 causes the support plate 26 to shift. The support plate 26 then pushes the flexible ear clip 12 to deform. The flexible ear clip 12 has a shape memory alloy sheet inside. One end of this alloy sheet is connected to the outer shell 1, and the outside is covered with silicone, allowing the flexible ear clip 12 to deform away from the bone conduction vibrator 11 in coordination with the support plate 26, thereby increasing the distance between the flexible ear clip 12 and the bone conduction vibrator 11. At this time, the user can place the bone conduction headphones on the outside of the ear.

[0029] Rotating knob 2 in the opposite direction causes the worm gear 21 to rotate in the opposite direction, which in turn causes the worm wheel 22 to rotate in the opposite direction. Under the action of the support mechanism, the flexible ear clip 12 approaches the bone conduction vibrator 11 to clamp the ear, and through the engagement of the worm gear 21 and the worm wheel 22, a self-locking function is achieved to prevent the flexible ear clip 12 from loosening.

[0030] Users can adjust the clamping force of the bone conduction headphones on their ears by controlling the number of rotations of knob 2. In this way, even if different users have different ear thicknesses, the bone conduction headphones can adjust the clamping force according to the actual ear thickness, thereby preventing the clamping force from affecting the sound quality if it is too weak or causing ear discomfort if it is too strong.

[0031] See Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the bone conduction vibrator 11 is equipped with an anti-fouling mechanism, which includes an anti-fouling cover 28 and a limiting mechanism. The anti-fouling cover 28 is disposed on the outside of the bone conduction vibrator 11. The limiting mechanism is disposed on the outer shell 1 and is used to restrict the anti-fouling cover 28 to the outside of the bone conduction vibrator 11. The limiting mechanism includes a screw tube 29 and a connecting tube 210. The screw tube 29 is sleeved on the outside of the bone conduction vibrator 11, and one side of the screw tube 29 is connected to the outer shell 1. The connecting tube 210 is threadedly connected to the screw tube 29 and is connected to the anti-fouling cover 28.

[0032] Specifically, the anti-fouling cover 28 is made of carbon fiber. When using the bone conduction headphones, the connecting tube 210 is placed on the outside of the bone conduction vibrator 11 and connected to the screw tube 29, and then the connecting tube 210 is rotated. Since the connecting tube 210 and the screw tube 29 are threadedly connected, the connecting tube 210 and the screw tube 29 limit each other, thereby fixing the anti-fouling cover 28 on the outside of the bone conduction vibrator 11.

[0033] When the bone conduction earphone is worn on the ear, since the carbon fiber material adopted by the dirt-proof cover 28 has good strength and conduction performance, the carbon fiber can effectively transmit sound during the working process of the bone conduction earphone, so as to ensure that the dirt-proof cover 28 does not interfere with the normal use of the bone conduction earphone. At the same time, the dirt-proof cover 28 can prevent earwax or other substances from accumulating at the contact point of the bone conduction vibrator 11.

[0034] When earwax or other substances accumulate outside the dirt-proof cover 28, the rotating connecting pipe 210 can separate the dirt-proof cover 28 from the bone conduction vibrator 11, so that the user can clean the dirt-proof cover 28, and avoid earwax or other substances from accumulating at the contact point of the bone conduction vibrator 11, thereby preventing the bone conduction earphone from having a decrease in sound quality or unclear audio signal transmission due to the accumulation of these substances.

[0035] Working principle: when the user uses the bone conduction earphone, the dirt-proof cover 28 is fixed outside the bone conduction vibrator 11 by the limiting mechanism. The flexible ear clip 12 is controlled to move away from the bone conduction vibrator 11 by the adjusting mechanism, at this time the user can place the bone conduction earphone outside the ear. Again, operate the adjusting mechanism to make the flexible ear clip 12 close to the bone conduction vibrator 11, and apply a squeezing force to the ear, so as to fix the bone conduction earphone outside the ear. At the same time, the user can adjust the clamping force of the bone conduction earphone on the ear by rotating the control knob 2, so that the bone conduction earphone can be adaptively adjusted according to the actual ear thickness.

[0036] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
