Description

Technical Field

[0001] The present invention relates to the field of bone conduction headphones, and specifically relates to a bone conduction headphone with a replaceable conduction piece. Background Art

[0002] In the existing market, bone conduction technology is mostly used in the military market. At the same time, with the continuous in-depth research on the technology, it is gradually entering people's daily lives. Since its sound conduction is achieved by the way of vibration sound transmission, it has strong anti-interference ability and does not need to receive sound through the external auditory canal for transmission. In daily life, it can receive external information while liberating both ears. Existing bone conduction speakers (bone conduction vibrators with moving iron structures in the military field) cannot have a frequency response curve like traditional speakers due to the constraints of their structures and material properties, resulting in a difficult position in the civilian market and greatly limited usage scenarios.

[0003] After the bone conduction headphones are used for a period of time, the sweat stains on people's surfaces will adhere to the surface of the conduction piece, making the conduction piece sticky with the skin on the human surface during subsequent use, thus resulting in poor comfort during use. When replacing the conduction piece with an externally provided replacement conduction piece, problems such as troublesome replacement, forgetting to carry, and damage are likely to occur, making it inconvenient for people to use. Therefore, it is necessary to propose a bone conduction headphone with a replaceable conduction piece. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a bone conduction headphone with a replaceable conduction piece.

An annular block is slidably connected in each of the two annular grooves. The inner rings of the two annular blocks penetrate and extend into the fixing grooves and are fixedly sleeved with a fixing rod. A second spring is sleeved on the rod wall of each of the two fixing rods. The two ends of the two second springs abut against the annular groove and the annular block respectively. One end of each of the two fixing rods penetrates and extends outside the support rod, and a fixing frame is fixedly connected to the end of each of the two fixing rods located outside the support rod. A conduction sheet is fixedly installed in each of the two fixing frames.

[0008] Specifically, the protection mechanism includes a second bearing fixedly installed on the upper surface of the machine body, and a second rotating rod is fixedly sleeved inside the second bearing.

A moving block is slidably connected in the moving cavity. A moving rod is fixedly connected to the outer side wall of the moving block corresponding to the position of the moving hole.

[0010] Specifically, both of the two fixing grooves are communicated with the moving cavity. One end of each of the two fixing rods away from the fixing frame penetrates and extends into the moving cavity, and the ends of the two fixing rods located inside the moving cavity are both arc-shaped.

[0011] Specifically, the two side edges of the outer side wall of the moving block are both inclined.

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0026] As Figures 1-7 shown, a bone conduction headphone with a replaceable conducting piece according to the present invention includes a body mechanism 1.

[0027] Among them, the body mechanism 1 includes a body 11. An installation groove 12 is opened on the lower surface of the body 11. An installation cavity 13 is opened inside the body 11 at a position above the installation groove 12. An installation hole 14 is commonly penetrated between the installation cavity 13 and the installation groove 12. A mounting block 15 is slidably connected in the mounting cavity 13. A mounting rod 16 is fixedly connected to the lower surface of the mounting block 15 corresponding to the position of the mounting hole 14. By limiting the mounting block 15 through the mounting cavity 13, the mounting seat 17 can only move within a certain range to prevent the magnetic part 18 and the conducting rod 19 from detaching. The lower end of the mounting rod 16 penetrates and extends into the installation groove 12 and is fixedly connected to an installation seat 17. A magnetic part 18 is fixedly installed on the lower surface of the installation seat 17. A conducting rod 19 is fixedly connected to the lower surface of the magnetic part 18. A first spring 110 is sleeved on the rod wall of the mounting rod 16 in the installation groove 12, and both ends of the first spring 110 abut against the top wall of the installation groove 12 and the upper surface of the installation seat 17 respectively. A fixing band 111 is fixedly connected to the outer side wall of the body 11. The first spring 110 will push the installation seat 17 downward, and the installation seat 17 will drive the magnetic part 18 and the conducting rod 19 downward to abut against the conducting piece 210, thus facilitating bone conduction.

[0028] Among them, the swapping mechanism 2 includes a first bearing 21 fixedly installed on the outer side wall of the machine body 11. A first rotating rod 22 is fixedly sleeved inside the first bearing 21. One end of the first rotating rod 22 penetrates and extends outside the machine body 11. Two support rods 23 are fixedly connected to the rod wall of the first rotating rod 22. A fixing groove 24 is provided at one end of each of the two support rods 23 away from the first rotating rod 22. An annular groove 25 is provided on the groove wall of each of the two fixing grooves 24. An annular block 26 is slidably connected in each of the two annular grooves 25. The inner rings of the two annular blocks 26 penetrate and extend into the fixing groove 24 and are fixedly sleeved with a fixing rod 27. A second spring 28 is sleeved on the rod walls of the two fixing rods 27. The two ends of the two second springs 28 are respectively abutted against the annular groove 25 and the annular block 26. One end of each of the two fixing rods 27 penetrates and extends outside the support rod 23. A fixing frame 29 is fixedly connected to the end of each of the two fixing rods 27 located outside the support rod 23. A conduction sheet 210 is fixedly installed in each of the two fixing frames 29. The pushing mechanism 4 includes a moving cavity 41 opened inside the first rotating rod 22. A moving hole 42 is penetrated through the cavity wall of the moving cavity 41. A moving block 43 is slidably connected in the moving cavity 41. A moving rod 44 is fixedly connected to the outer side wall of the moving block 43 corresponding to the position of the moving hole 42. The two side edges of the outer side wall of the moving block 43 are both inclined. The ends of the moving rod 44 away from the moving block 43 penetrate and extend outside the first rotating rod 22. A handle 45 is fixedly connected to the end of the moving rod 44 located outside the first rotating rod 22. Each of the two fixing grooves 24 is communicated with the moving cavity 41. One end of each of the two fixing rods 27 away from the fixing frame 29 penetrates and extends into the moving cavity 41. The ends of the two fixing rods 27 located in the moving cavity 41 are both arc-shaped. The moving rod 44 can be pulled by the handle 45. The moving rod 44 will pull the moving block 43 to move in the moving cavity 41. The moving block 43 will extrude one end of the fixing rod 27 located in the moving cavity 41 in the moving cavity 41 and push it outward, so that the fixing rod 27 drives the fixing frame 29 and the conduction sheet 210 to extend outward, avoiding the fixing frame 29 from abutting against the outer side wall of the machine body 11 and affecting its rotation. Then, rotation can be performed through the first bearing 21 and the first rotating rod 22, so as to swap between the two fixing frames 29 and the two conduction sheets 210. Then, the moving rod 44 can be pushed by the handle 45. The moving rod 44 drives the moving block 43 to move and releases the support for the fixing rod 27. At this time, the second spring 28 will push the annular block 26 under the support of the annular groove 25. The annular block 26 will drive the fixing rod 27, the fixing frame 29 and the conduction sheet 210 to reset, thus completing the swapping of the conduction sheet 210, making the comfort of the replaced conduction sheet 210 higher, and the replacement is relatively simple and convenient, and there will be no phenomenon of forgetting to carry and external bump damage.

[0029] Among them, the protection mechanism 3 includes a second bearing 31 fixedly installed on the upper surface of the machine body 11. A second rotating rod 32 is fixedly sleeved inside the second bearing 31. The upper end of the second rotating rod 32 penetrates and extends outside the machine body 11. One end of the second rotating rod 32 located outside the machine body 11 is fixedly connected with a protection plate 33. A cleaning cloth 34 is fixedly connected to the lower surface of the protection plate 33. The cleaning cloth 34 abuts against the upper surface of one of the conduction sheets 210. The conduction sheet 210 in the fixed frame 29 is protected by the protection plate 33. When replacement is needed, the protection plate 33 can be rotated. The protection plate 33 can rotate based on the second rotating rod 32 through the cooperation of the second rotating rod 32 and the second bearing 31. At this time, the protection plate 33 will disengage from the upper surface of the fixed frame 29 and the conduction sheet 210. At the same time, the upper surface of the conduction sheet 210 can be cleaned by the cleaning cloth 34 on the protection plate 33.

[0030] During use, the conduction sheet 210 in the fixed frame 29 can be protected by the protection plate 33. When replacement is needed, the protection plate 33 can be rotated. The protection plate 33 can rotate based on the second rotating rod 32 through the cooperation of the second rotating rod 32 and the second bearing 31. At this time, the protection plate 33 will disengage from the upper surface of the fixed frame 29 and the conduction sheet 210. At the same time, the upper surface of the conduction sheet 210 can be cleaned by the cleaning cloth 34 on the protection plate 33. Then, the moving rod 44 can be pulled by the handle 45. The moving rod 44 will pull the moving block 43 to move in the moving cavity 41. The moving block 43 will squeeze one end of the fixed rod 27 located in the moving cavity 41 and push it outward, so that the fixed rod 27 drives the fixed frame 29 and the conduction sheet 210 to extend outward, avoiding the fixed frame 29 from abutting against the outer wall of the machine body 11 and affecting its rotation. Then, rotation can be performed through the first bearing 21 and the first rotating rod 22 to swap between the two fixed frames 29 and the two conduction sheets 210. Then, the moving rod 44 can be pushed by the handle 45. The moving rod 44 drives the moving block 43 to move and releases the support for the fixed rod 27. At this time, the second spring 28 will push the annular block 26 under the support of the annular groove 25. The annular block 26 will drive the fixed rod 27, the fixed frame 29 and the conduction sheet 210 to reset, thus completing the replacement of the conduction sheet 210, making the replaced conduction sheet 210 more comfortable to use, and the replacement is relatively simple and convenient, and there will be no phenomenon of forgetting to carry and external collision damage.
