Description

Technical Field

[0001] The present invention relates to the field of earphones, and more particularly to a bone conduction earphone. Background Art

[0002] Traditional in-ear or over-ear headphones mainly use air conduction. At present, bone conduction headphones have appeared on the market. They mainly use sound vibrations to push human tissues and bones, thereby stimulating the auditory nerves in the cochlea and allowing people to hear sounds. Bone conduction headphones do not require any foreign objects to be placed in the user's ears, keeping both ears open, which effectively avoids the problem of traditional air conduction headphones being unable to accurately perceive the external environment when worn.

[0003] Bone conduction headphones are mainly composed of a neck hanging piece and two bone conduction earphones. The existing bone conduction earphones of the same model and brand are of consistent and fixed size. However, when consumers of different ages and with different head circumferences use them, the earphones of the bone conduction earphones cannot fit well with the wearing position. The misalignment of the earphones and the wearing position will cause a great impact on the conduction of the earphone sound quality and greatly reduce the user experience. In addition, if the earphones cannot fit well with the wearing position, resulting in misalignment of the earphones and the wearing position, the firmness of the earphone fixation will be further reduced, and the earphones are easy to fall off during use, causing damage to the earphones. Summary of the invention

[0004] In view of the problems existing in the prior art, the object of the present invention is to provide a bone conduction earphone.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0010] Further, the first air pipe is in an L shape. One end of the first air pipe passes through the inside of the rear hanging member and enters the inside of the arc-shaped airbag. A dust-proof net is arranged on the top of the air pump chamber.

[0011] Further, the multi-angle buffer assembly includes two anti-collision rings fixed to the outer surface of the earphone head and three first rectangular support rods fixed to the middle of the outer surface of the earphone head. A U-shaped plate slides on the outer surface of the first rectangular support rod. A first spring is sleeved on the outer surface of the first rectangular support rod. Two second rectangular support rods are fixedly connected to both sides of the inner surface of the U-shaped plate. A slider is slidably connected to the outer surface of the second rectangular support rod. An impact block is fixedly connected to the top of the slider. Two second springs are sleeved on the outer surface of the second rectangular support rod.

[0012] Further, the impact block is located between the two anti-collision rings. Rubber pads are arranged on the sides of the anti-collision rings close to each other, and the rubber pads on both sides of the impact block are in contact with each other.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In this solution, by setting the adjustment component, pulling the sleeve rod to slide on the outside of the receiving rod, the sleeve rod drives the earphone head to continuously change its position. Rotating the receiving rod to rotate around the arc-shaped block, the sleeve rod can drive the earphone head to swing at an angle, so that the earphone head can be adjusted to more positions, with a wider adjustment range and better adaptability, which can meet the wearing and use of different users, avoid the disadvantage that the earphone head of the bone conduction earphone cannot be adjusted, and improve the user experience.

[0019] 2. In this solution, by setting the airbag component, inflating the arc-shaped airbag, the arc-shaped airbag will expand and contact and support the user's head, so that the user's head fully contacts the arc-shaped airbag. Since the texture of the arc-shaped airbag is relatively soft, the user feels more comfortable when wearing, and the full contact between the user's head and the arc-shaped airbag avoids the indentation caused by the rear hanging part.

[0020] 3. In this solution, by setting the multi-angle buffer component, the slider slides on the outside of the second rectangular support rod and the U-shaped plate slides on the outside of the first rectangular support rod. The slider squeezes the second spring, and the friction generated by the sliding eliminates the force. At the same time, when the impact block moves on the second rectangular support rod through the slider, it will contact and rub against the rubber pad on the anti-collision ring, further improving the buffering effect. The setting of the anti-collision ring makes the earphone head always keep a certain distance from the ground, effectively ensuring that the earphone head can be well protected when it falls, without being damaged, and avoiding wear on the outer surface of the earphone head.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 10 A bone conduction earphone comprises a rear hanger 1, both ends of the rear hanger 1 are fixedly connected with module blocks 2, one side of the two module blocks 2 is fixedly connected with ear hooks 3, one end of the ear hooks 3 is fixedly connected with an adjustable component 4 that can be adjusted at will, and a noise reduction earphone component 5 is inserted at the bottom of the module block 2.

[0042] like Figure 2 - Figure 4 As shown, the adjustment component 4 includes an arc-shaped connecting part 41 fixed on one side of the ear hook part 3, the bottom of the arc-shaped connecting part 41 is hinged with an arc-shaped block 411, the bottom of the arc-shaped block 411 is fixedly connected with a storage rod 42, the outer surface of the storage rod 42 is sleeved with a sleeve rod 43, a storage groove 413 is provided at the bottom of the inner part of the arc-shaped connecting part 41, the inside of the storage groove 413 is slidably connected with a third rack 414, the top of the third rack 414 is fixedly connected with a fourth spring 415, the outer surface of the arc-shaped block 411 is fixedly connected with an arc-shaped rack 416, a groove 44 is provided on the front side of the storage rod 42, one side of the inner surface of the groove 44 is fixedly connected with a second rack 410, a through groove 48 is provided on the front side of the sleeve rod 43, the inside of the through groove 48 is slidably connected with a first rack 49, one side of the first rack 49 is fixedly connected with a third spring 412, and one side of the sleeve rod 43 is fixedly connected with an earphone head 45.

[0043] The first rack 49 is located inside the groove 44, the third spring 412 is located inside the through groove 48, one side of the third spring 412 is fixedly connected to one side of the through groove 48, the groove 44 and the second rack 410 are meshed with each other, the third rack 414 and the arc-shaped rack 416 are meshed with each other, a vertical groove is provided on one side of the storage groove 413, and a toggle rod is slidably connected inside the vertical groove, the third rack 414 is fixedly connected to one side of the toggle rod, an airbag assembly 46 is provided on one side inside the module block 2, and a multi-angle buffer assembly 47 for buffering is provided on the outer surface of the earphone head 45.

[0044] When different users wear bone conduction headphones, if the earphone head 45 is offset from the position where it needs to fit, the best wearing method can be achieved by continuously adjusting the position of the earphone head 45. First, the first rack 49 is moved to slide inside the through groove 48 and the third spring 412 is squeezed to move the first rack 49 and the second rack 410 away from each other, and the fixing between the sleeve rod 43 and the storage rod 42 is released. The sleeve rod 43 is pulled to slide on the outside of the storage rod 42, and the earphone head 45 is continuously changed in position through the sleeve rod 43, and the squeezing of the first rack 49 by the third spring 412 is released. By pressing down, the first rack 49 is quickly reset and meshed with the second rack 410, and the third rack 414 is driven to move toward the inside of the storage groove 413 by pushing the toggle rod, so that the third rack 414 and the arc-shaped rack 416 are moved away from each other. At this time, the storage rod 42 can be rotated around the arc block 411, and the earphone head 45 can be driven to swing in angle through the sleeve rod 43, so that the earphone head 45 has more adjustable positions, a wider adjustment range, and better adaptability, which can meet the wearing and use needs of different users, avoid the disadvantage of the earphone head 45 of the bone conduction earphone that cannot be adjusted, and improve the user experience.

[0045] like Figure 5 As shown, the airbag assembly 46 includes an air pump compartment 461 opened on one side of the module block 2 and an arc-shaped airbag 464 fixed on the inner side of the rear hanger 1, an air pump 462 is fixedly connected to one side of the inner surface of the air pump compartment 461, and a first air pipe 463 is fixedly connected to the output end of the air pump 462.

[0046] The first air pipe 463 is L-shaped, and one end of the first air pipe 463 passes through the interior of the rear hanging component 1 and enters into the interior of the arc-shaped air bag 464 . A dustproof net is arranged on the top of the air pump compartment 461 .

[0047] When the user wears the earphones, the force generated by the expansion deformation of the rear hanger 1 is mainly used to clamp the user's head. However, the rear hanger 1 is relatively hard. If it is clamped on the user's head for a long time, it will cause indentations on the user's head and cause a certain amount of pain. In addition, the rear hanger 1 does not completely fit the head, resulting in a smaller force-bearing area, which intensifies the pain at the force-bearing location. Therefore, the air pump 462 is turned on by the terminal mobile phone to work, and the air pump 462 conveys airflow to the inside of the first air pipe 463, and the airflow enters the inside of the arc-shaped airbag 464. As the gas inside the arc-shaped airbag 464 increases, the arc-shaped airbag 464 gradually expands and fills up. The expansion of the arc-shaped airbag 464 will contact and support the user's head, so that the user's head is fully in contact with the arc-shaped airbag 464. Since the texture of the arc-shaped airbag 464 is relatively soft, the user is more comfortable when wearing it, and the user's head is in full contact with the arc-shaped airbag 464, avoiding the indentation caused by the rear hanger 1.

[0048] As Figure 6 and Figure 7 shown, the multi-angle buffer assembly 47 includes two anti-collision rings 471 fixed on the outer surface of the earphone head 45 and three first rectangular support rods 476 fixed at the middle of the outer surface of the earphone head 45. A U-shaped plate 473 slides on the outer surface of the first rectangular support rod 476. A first spring 475 is sleeved on the outer surface of the first rectangular support rod 476. Both sides of the inner surface of the U-shaped plate 473 are fixedly connected with second rectangular support rods 478. A slider 474 is slidably connected to the outer surface of the second rectangular support rod 478. An impact block 472 is fixedly connected to the top of the slider 474. Two second springs 477 are sleeved on the outer surface of the second rectangular support rod 478.

[0049] The impact block 472 is located between the two anti-collision rings 471. Rubber pads are arranged on the sides of the anti-collision rings 471 close to each other, and the rubber pads on both sides of the impact block 472 are in contact with each other.

[0050] Although it is difficult for the earphone to fall off the head when wearing the bone conduction earphone, during the process when the earphone is not being worn, the earphone may fall and drop. Moreover, the interior of the earphone head 45 on the bone conduction earphone is relatively delicate, and the impact generated by the fall will damage the interior of the earphone head 45. A slight impact will affect the sound quality transmitted by the earphone head 45, and in serious cases, the earphone head 45 will be unable to be used, reducing the service life of the earphone head 45;

[0051] Therefore, a multi-angle buffer component 47 is provided. When the bone conduction headset drops, the headset head 45 will contact and approach the ground. The impact block 472 on the headset head 45 will contact the ground in advance. When the impact block 472 is squeezed, it will drive the C-shaped plate 473 to slide outside the first rectangular support rod 476 through the slider 474 and the second rectangular support rod 478, squeezing the first spring 475, so that all the impact force is applied to the first spring 475, thereby decelerating the headset head 45 during the descending process. And when receiving a force that is not perpendicular to the impact block 472, the force will be decomposed into two forces parallel to the first rectangular support rod 476 and the second rectangular support rod 478 respectively, pushing the slider 474 to slide outside the second rectangular support rod 478 and the C-shaped plate 473 to slide outside the first rectangular support rod 476. The slider 474 squeezes the second spring 477, and the force is eliminated through the friction generated by the sliding. At the same time, when the impact block 472 moves on the second rectangular support rod 478 through the slider 474, it will contact and rub against the rubber pad on the anti-collision ring 471, further improving the buffering effect. And the setting of the anti-collision ring 471 makes the headset head 45 always keep a certain distance from the ground, effectively ensuring that the headset head 45 can be well protected when it falls, without being damaged and avoiding abrasion on the outer surface of the headset head 45.

[0052] As Figure 8 shown, the noise-canceling headset assembly 5 includes a plug 51 inserted into the module block 2. The bottom of the plug 51 is fixedly connected with a connecting wire 52. The bottom of the connecting wire 52 is fixedly connected with a headset body 53. One side of the headset body 53 is fixedly connected with a cylinder 57. The outer surface of the cylinder 57 is rotatably connected with an earhook 54. The side of the headset body 53 away from the earhook 54 is fixedly connected with an airbag earplug 55.

[0053] One side of the cylinder 57 is fixedly connected with a limiting block. The earhook 54 is arc-shaped. The bottom of the headset body 53 is fixedly connected with a filling assembly 56.

[0054] When the bone conduction headset is worn, the surrounding environment sounds can be perceived by both ears. However, in a noisy environment when a quiet state needs to be maintained, the traditional bone conduction headset cannot achieve it well. Therefore, the headset body 53 is inserted into the module block 2, and the noise-canceling function of the traditional in-ear headset is exerted by wearing the headset body 53. Along with the surrounding environment, different wearing modes can be switched well, effectively improving the functionality of the bone conduction headset and avoiding the trouble caused by changing different headsets back and forth. By rotating the earhook 54, the earhook 54 can be buckled on the auricle to ensure that when the headset body 53 moves during wearing, the headset body 53 will not fall off from the inner ear.

[0055] like Fig. 9 and Fig.10 As shown, the filling component 56 includes a rectangular frame 561 fixed to the bottom of the earphone body 53, and telescopic shafts 567 are slidably connected to both sides of the rectangular frame 561, and a piston 566 is fixedly connected to the side where the two telescopic shafts 567 are close to each other, and a movable plate 564 is fixedly connected to the side where the two telescopic shafts 567 are away from each other. The internal threads of the two movable plates 564 are connected to bidirectional threaded rods 563, the bottom of the rectangular frame 561 is fixedly connected to a fixed plate 562, and one side of the rectangular frame 561 is fixedly connected to a second air pipe 565.

[0056] The bidirectional threaded rod 563 is located inside the fixed plate 562, and the bidirectional threaded rod 563 is connected to the fixed plate 562 through a bearing. One side of the second air pipe 565 extends to the inside of the airbag earplug 55, and the inside of the rectangular frame 561 is connected to the inside of the airbag earplug 55 through the second air pipe 565.

[0057] When wearing the in-ear earphone body 53, the airbag earplug 55 is inserted into the ear, which can not only reduce noise well, but also improve the stability of the earphone body 53 when wearing. However, the ear canals of different users are of different sizes. When the airbag earplug 55 is worn for too long, it will cause pain to the user's ear canal. If the airbag earplug 55 is too small, the noise reduction effect and sound quality transmission of the earphone body 53 will be reduced. Therefore, by rotating the two-way threaded rod 563, the two movable plates 564 are driven to approach each other, and the two movable plates 564 drive the two pistons 566 to approach each other through the telescopic shaft 567, and the gas inside the rectangular frame 561 is squeezed into the inside of the airbag earplug 55 through the second air pipe 565 to expand the airbag earplug 55. By rotating the two-way threaded rod 563 in the opposite direction, the gas inside the airbag earplug 55 can be pumped into the inside of the rectangular frame 561 to reduce the volume of the airbag earplug 55, so that the user can change the size of the airbag earplug 55 according to his own needs to ensure that the airbag earplug 55 is worn in the best comfortable state.

[0058] Instructions for use: First, by adjusting the coordination between the components of the assembly 4, the position of the earphone head 45 can be continuously adjusted to adjust the earphone head 45 to the best position for the user, thereby ensuring that the sound quality transmission of the earphone head 45 reaches the best effect. At the same time, the interior of the arc-shaped airbag 464 is inflated so that it is in full contact with the user's head after expansion, thereby improving the wearing comfort of the user. Under the action of the multi-angle buffer assembly 47, when the earphone head 45 falls accidentally, the three impact blocks 472 and the coordination of the components of the multi-angle buffer assembly 47 can effectively buffer the impact force, thereby ensuring the safety of the earphone head 45.

[0059] Secondly, by providing the earphone main body 53, two different modes can be switched on the bone conduction earphone according to actual needs, thereby improving the practicality of the bone conduction earphone. At the same time, with the mutual cooperation of the various parts of the filling component 56, the size of the airbag earplug 55 can be adjusted to ensure that the user's ears are more comfortable and pain-free when wearing the earphone main body 53.

[0060] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
