Description

Technical Field

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

[0002] Bone conduction is a sound transmission method that converts sound into mechanical vibrations of different frequencies and transmits sound waves through the human skull, bony labyrinth, inner ear lymph, spiral organ, auditory nerve, and auditory center. 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 spread in the air.

[0003] Current bone conduction headphones mainly convert external sounds into electrical signals through the headphone body, and then the headphone body cooperates with the internal vibrator to convert the electrical signals into bone vibration sound waves and directly transmit them to the ear bones for sound bone conduction. However, due to the different head shapes of each person, the vibrator on the bone conduction headphones cannot fit well on the head when the bone conduction headphones are worn, resulting in a gap between the vibrator and the head, reducing the efficiency of bone conduction sound waves. Moreover, current fixed conduction headphones are basically installed in one piece inside the bone conduction headphones. In this way, the vibrator cannot be quickly removed from the bone conduction headphones during maintenance or replacement, which increases the disassembly and assembly time. At the same time, when using the bone conduction headphone vibrator to transmit low-frequency sound waves, since there is no enclosed space formed inside the ear, the transmission is often not in place.

[0021] When in use, first place the connection box 32 at the lower end of the fixed block 11, and then press the pressing plate 28 with the anti-slip pad 29 by hand. When the pressing plate 28 is subjected to force, it will push the fixed rod 22. The fixed rod 22 is subjected to force and cooperates with the sliding limit of the sliding rod 24 and the third sliding groove 23 to stably move and push the side plate 20. The side plate 20 will push the sliding plate 21 to slide inside the second sliding groove 13. At the same time, the side plate 20 is subjected to force and cooperates with the fixed plate 17 to compress a plurality of springs 19 and telescopic damping 18. As the springs 19 and telescopic damping 18 shrink, the side plate 20 is driven to move. When the side plate 20 moves, the connecting plate 26 is driven to move through the vertical rod 25. At this time, the connection box 32 is pushed, and the vertical rod 25 and the connecting plate 26 are passed through the inlet and outlet 33 of the connection box 32 to enter When the second magnetic block 30 at the upper end of the plug block 31 is magnetically connected to the first magnetic block 16, the upper end of the connection box 32 and the lower end of the fixed block 11 are stably against each other. At this time, the pressing plate 28 is released. When the pressing plate 28 loses pressure, the side plate 20 is stably driven to reset under the elastic action of the spring 19 and the telescopic damping 18 in conjunction with the sliding limit action of the second slide groove 13 and the slide plate 21. The side plate 20 drives the vertical rod 25 to move inside the inlet and outlet 33. At the same time, when the vertical rod 25 moves, it will drive the connecting plate 26 to move.

When the two sides of the mounting plate 9 move, the slider 6 will be driven to slide inside the first slide groove 4. When the transmission sheet 37 on the mounting shell 35 and the first vibrator 36 are driven to fit stably with the user's head, the bolt 8 is passed through the threaded hole 5 and threadedly fastened inside the threaded groove 7. Then the user hangs the limiting ring 38 on the rear end of the ear. The limiting ring 38 will synchronously and stably fit the earphone body 1, the mounting shell 35 and the first vibrator 36 to the head. At the same time, the second vibrator 44 is installed inside the ear through the connecting line 43 to form a closed space inside the ear. When the earphone body 1 loses support, the limiting belt 42 at the upper end of the limiting ring 38 will limit the head and neck to prevent the earphone body 1 from falling to the ground and being impacted. When bone conduction is required, when external sound is transmitted, the earphone body 1 converts the sound into an electrical signal through the internal dedicated accessories, and then the earphone body 1 transmits the electrical signal to the first vibrator 36 and the second vibrator 44 through a dedicated connector. At the same time, the first vibrator 36 and the second vibrator 44 will convert the electrical signal into vibration sound waves and transmit them through bone conduction and skin conduction respectively, so as to facilitate the stable transmission of sound waves of different frequencies.
