Description

Technical Field

[0001] The present invention relates to the field of bone conduction earphones, and in particular to a bone conduction earphone that fits the ear bone. Background Art

[0002] Bone conduction is a method of sound conduction that converts sound into mechanical vibrations of different frequencies and transmits sound waves through the human skull, bony labyrinth, inner ear lymph, spiral organ, and auditory center. Compared with the classic sound conduction method of generating sound waves through the diaphragm, bone conduction eliminates many steps in sound wave transmission and can achieve clear sound restoration in noisy environments. Moreover, the sound waves will not affect others due to spreading in the air.

[0003] When using bone conduction, the speaker needs to fit the ear bone. However, many existing bone conduction headphones do not have specifications that are fully adapted to different wearers. As a result, the headphones cannot completely fit the ear bones when worn, which will cause the sound quality of the headphones to be damaged. In addition, existing bone conduction headphones are generally worn around the wearer's head. When the headphones do not match the wearer's head, the headphones will often become loose, which may easily cause the headphones to fall off the ears. Summary of the Invention

[0014] Beneficial effects of the present invention:

[0015] (1) The bone conduction earphones according to the present invention are designed to fit the ear bones by bending the U-shaped tube according to the width of the wearer's head so that the U-shaped tube fits the head, then pulling the ball to straighten the drawstring, and then engaging the clamping block on the drawstring with the corresponding clamping slot.

The telescopic tube slides out stably through the slider and the slide groove, so that the fixed shell drives the speaker to fit the ear bones, thereby preventing the earphones from failing to fit the ear bones completely and causing the sound quality to be damaged.

The U-shaped tube 1 is pulled by the arc bar 21 and the ring 27 so that the bend of the U-shaped tube 1 fits the wearer's head, preventing the earphones from loosening and falling off the head.

[0029] Specifically, the steering assembly 3 includes a wire 31, which is inserted into the interior of the U-shaped tube 1. Both ends of the wire 31 are fixedly connected to a connector 32. The two connectors 32 are clamped inside the two cylinders 33. One end of the two cylinders 33 is provided with a rotation groove 34. The two connectors 32 are clamped inside the two rotation grooves 34. The other ends of the two connectors 32 are fixedly connected to a power line 35. The two power lines 35 are inserted into the interior of two wire holes 36. The two wire holes 36 are opened on the surface of the two cylinders 33. A circular tube 37 is fixedly connected to the outer wall of 33, and two power cords 35 are plugged into the inside of the two circular tubes 37. The two circular tubes 37 are rotatably connected to the surfaces of four plywood 38. Two arc plates 39 are fixedly connected to the four plywood 38. The two ends of the U-shaped tube 1 are respectively fitted with the four plywood 38, pushing the circular tube 37 to drive the cylinder 33 to rotate. When the cylinder 33 rotates, it drives the wire 31 to rotate inside the rotating groove 34, thereby changing the angle between the circular tube 37 and the U-shaped tube 1, so that the fixed shell 55 can be driven to fit the ear bone.

[0030] Specifically, the control component 4 includes two arc blocks 41, the two arc blocks 41 are fixedly connected to the outer circular side walls of the four splints 38, the interiors of the four arc blocks 41 are provided with arc grooves 42, the interiors of the two arc grooves 42 are plugged with belts 44, the side walls of the two belts 44 are fixedly connected with multiple fixed blocks 43 at equal distances, the ends of the two belts 44 away from the splints 38 are fixedly connected with push blocks 45, the surfaces of the two belts 44 are sleeved with fixed frames 46, the two fixed frames 46 are sleeved on the surfaces of the two circular tubes 37, and the two fixed frames The inner walls of the other ends of 46 are respectively sleeved on the surfaces of two rubber blocks 47, and the two rubber blocks 47 are respectively fixedly connected to the surfaces of the two circular tubes 37, pushing the pushing block 45 to drive the belt 44 to move, so that the belt 44 drives the fixed block 43 to move inside the arc groove 42, and pushes the fixed block 43 and the U-shaped tube 1 to be squeezed against each other through the arc groove 42, and then pushes the fixed frame 46 to fit with the surface of the rubber block 47, and then makes the fixed frame 46 squeeze the belt 44 to push the fixed block 43 to be fixed to the outer wall of the circular tube 37, so that the angle of the circular tube 37 is fixed.

[0031] Specifically, the extension component 5 includes two sleeves 51, which are fixedly sleeved on the outer wall of the lower end of the two circular tubes 37, and two sliders 52 are fixedly connected to the inner wall of the other end of the two sleeves 51. The four sliders 52 are slidably connected to the inside of four slide grooves 53. The four slide grooves 53 are opened on the surface of the two telescopic tubes 54. The other ends of the two telescopic tubes 54 are fixedly connected to a fixed shell 55, and the interior of the two fixed shells 55 is clamped with a speaker 56. The inner walls of the two telescopic tubes 54 are symmetrically fixed with a sealing plate 57. Pushing the fixed shell 55 drives the telescopic tube 54 to move out of the sleeve 51, and the telescopic tube 54 slides out stably through the sliders 52 and the slide groove 53. The slide groove 53 is blocked by the sealing plate 57 to prevent water from entering the telescopic tube 54. The position of the fixed shell 55 is adjusted by the telescopic length of the telescopic tube 54, so that the fixed shell 55 drives the speaker 56 to fit against the ear bone, preventing the sound quality from being damaged due to the inability of the earphone to fully fit against the ear bone.

[0036] When in use, first bend the U-shaped tube 1 according to the width of the wearer's head so that the U-shaped tube 1 fits the head, then pull the ball 26 to straighten the drawstring 25, and then engage the clamping block 24 on the drawstring 25 with the corresponding clamping groove 23, and pull the U-shaped tube 1 through the arc bar 21 and the ring 27 to make the bend of the U-shaped tube 1 fit the wearer's head, preventing the earphones from loosening and falling off the head, and then push the circular tube 37 to drive the cylinder 33 to rotate. When the cylinder 33 rotates, it drives the wire 31 to rotate inside the rotating groove 34, thereby changing the angle between the circular tube 37 and the U-shaped tube 1, so that the fixed shell 55 can fit the ear bone, and then push the pushing block 45 to drive the belt 44 to move, so that the belt 44 drives the fixing block 43 to move into the arc groove 42, and the moving belt 44 and the fixing block 43 are pushed by the arc groove 42 to squeeze the U The surface of the U-shaped tube 1 is pressed against the fixing block 43 and the U-shaped tube 1, and then the fixing frame 46 is pushed to fit with the surface of the rubber block 47, so that the fixing frame 46 squeezes the belt 44 to push the fixing block 43 to fit with the outer wall of the circular tube 37, so that the angle of the circular tube 37 is fixed, so that the speaker 56 of the earphone fits the earphone. At the same time, when the length of the speaker 56 of the earphone is not enough to fit the ear bone, the fixing shell 55 is pushed to drive the telescopic tube 54 to move out of the sleeve 51, and the telescopic tube 54 is made to slide out stably through the slider 52 and the slide groove 53, and the slide groove 53 is blocked by the sealing plate 57 to prevent water from entering the telescopic tube 54. The position of the fixing shell 55 is adjusted by the telescopic length of the telescopic tube 54, so that the fixed shell 55 drives the speaker 56 to fit with the ear bone, thereby preventing the sound quality from being damaged due to the inability of the earphone to fully fit the ear bone.
