[0031] Please also read Figures 1 to 6 , the ear-hook earphone provided in the embodiment of the present application is now described.
[0032] See also Figure 1 and Figure 2The earhook earphone comprises: an earphone body 100, an earhook 200 and an adjustment assembly 300, one end of the earhook 200 is a connecting end 201, and the connecting end 201 is provided with a first mating surface 202, the adjustment assembly 300 comprises a sleeve 10, a fixing member 20 and a torsion spring 30, the sleeve 10 is provided with a second mating surface 11, and the second mating surface 11 is slidably matched with the first mating surface 202 along the central axis a, a positioning column 12 is fixedly arranged in the sleeve 10, the fixing member 20 comprises a shaft body 21 and a transition part 22, the sleeve 10 is rotatably sleeved on the shaft body 21, one end of the transition part 22 is connected to the shaft body 21, and the other end is located outside the sleeve 10 and connected to the earphone body 100, the torsion spring 30 is arranged in the sleeve 10, and is fixedly sleeved on the positioning column 12, one end of the torsion spring 30 extends to the outside of the sleeve 10 and is connected to the earphone body 100, and is used to provide a restoring force for the rotation of the earphone body 100.
[0033] The ear hook 200 is curved and can be adapted to the shape of the user's auricle, so that the ear hook 200 can be hung on the user's ear.
[0034] It should be noted that in the embodiment of the present application, along the central axis a refers to the axial direction of the central axis a, and around the central axis a refers to the circumferential direction of the central axis a. The ear-hook earphones are worn on the user's ears, and the central axis a extends roughly in the vertical direction.
[0035] The axial direction of the sleeve 10 is parallel to the central axis a, and the second mating surface 11 of the sleeve 10 is slidably connected with the first mating surface 202 of the connecting end 201 along the central axis a, so that the second mating surface 11 of the sleeve 10 and the first mating surface 202 of the connecting end 201 can slide relative to each other along the central axis a, thereby enabling the sleeve 10 to slide relative to the connecting end 201 along the central axis a, and when the sleeve 10 slides relative to the connecting end 201 along the central axis a, the sleeve 10 moves synchronously along the driving shaft 21 along the central axis a, and the shaft 21 drives the earphone body 100 to move relative to the ear hook 200 along the central axis a through the adapter 22, thereby adjusting the distance between the earphone body 100 and the ear hook 200 on the central axis a.
[0036] It should be noted that there is a preset damping between the second mating surface 11 and the first mating surface 202. When the sleeve 10 slides to the preset position along the center axis a, the sleeve 10 can be maintained at the preset position along the center axis a to position the earphone body 100 on the center axis a and prevent the earphone body 100 from shaking up and down along the center axis a relative to the ear hook 200.
[0037] The shaft 21 is coaxial with the sleeve 10, and the sleeve 10 is rotatably mounted on the shaft 21, so that the sleeve 10 and the shaft 21 can rotate relative to each other around the central axis a. For example, when the shaft 21 rotates around the central axis a relative to the sleeve 10, the shaft 21 drives the earphone body 100 to rotate around the central axis a relative to the ear hook 200 through the adapter 22 to adjust the deflection angle of the earphone body 100 relative to the ear hook 200.
[0038] It can be understood that the sleeve 10 can slide along the central axis a relative to the connecting end 201, but the sleeve 10 cannot rotate around the central axis a relative to the connecting end 201; the sleeve 10 can rotate around the central axis a relative to the shaft body 21, but the sleeve 10 cannot slide along the central axis a relative to the shaft body 21.
[0039] The torsion spring 30 is arranged in the sleeve 10 and fixedly sleeved on the positioning column 12. One end of the torsion spring 30 extends outside the sleeve 10 and is connected to the earphone body 100. When the earphone body 100 is deflected relative to the ear hook 200 during wearing, the torsion spring 30 provides a restoring force for the earphone body 100, so that the earphone body 100 has a tendency to return to the original position, so that the earphone body 100 can be forced to fit on the user's ear during wearing. The magnitude of the restoring force can be determined according to experiments, with the goal of meeting the needs but not pressing the user's ear to make the user's ear uncomfortable.
[0040] Compared with the prior art, the ear-hook earphone provided by the present application is connected by slidingly fitting the second mating surface 11 of the sleeve 10 with the first mating surface 202 of the connecting end 201 along the central axis a, so that the sleeve 10 can slide along the central axis a relative to the connecting end 201. When the sleeve 10 slides, the fixing member 20 drives the earphone body 100 to move along the central axis a relative to the earhook 200 to adjust the distance between the earphone body 100 and the earhook 200 on the central axis a. In this way, when wearing the earphone, the user can adjust the distance between the earphone body 100 and the earhook on the central axis a according to their own needs. 200, so that the earphone body 100 can be worn in place, which is beneficial to improving the wearing comfort of the user, and the sleeve 10 is rotatably mounted on the shaft 21, so that the shaft 21 can drive the earphone body 100 to rotate relative to the ear hook 200 through the adapter 22, so that the earphone body 100 can better fit the user's ear. In addition, by connecting one end of the torsion spring 30 fixedly mounted on the positioning column 12 to the earphone body 100, the earphone body 100 can fit the user's ear more stably and is not easy to fall off, and can be adapted to more users, which is beneficial to improving the user experience.
[0041] In one embodiment of the present application, the maximum displacement of the second mating surface 11 sliding relative to the first mating surface 202 along the central axis a is 2 mm-4 mm.
[0042] Optionally, the maximum displacement of the second mating surface 11 sliding relative to the first mating surface 202 along the central axis a is 2 mm, 2.5 mm, 3 mm, 3.5 mm or 4 mm.
[0043] By setting the maximum sliding displacement of the second mating surface 11 relative to the first mating surface 202 along the central axis a to 2mm-4mm, the maximum adjustment distance between the earphone body 100 and the ear hook 200 on the central axis a is 2mm-4mm, so that the ear hook earphone can adapt to most users.
[0044] The earphone body 100 can rotate around the midline axis relative to the ear hook 200 within a range of 0°-30°.
[0045] In one embodiment of the present application, see Figure 2 A partition 13 is provided in the sleeve 10, and the partition 13 divides the internal space of the sleeve 10 into a first inner cavity 14 and a second inner cavity 15 along the central axis a. The shaft body 21 is rotatably disposed in the first inner cavity 14, the positioning column 12 and the torsion spring 30 are both disposed in the second inner cavity 15, and one end of the positioning column 12 is connected to the partition 13.
[0046] Optionally, the partition 13 and the sleeve 10 are formed integrally.
[0047] Optionally, see Figure 2 and Figure 6 The positioning column 12 and the sleeve 10 are integrally formed. The positioning column 12 is a rectangular structure. The torsion spring 30 is formed with a rectangular hole. The torsion spring 30 is sleeved on the positioning column 12 through the rectangular hole, and the positioning column 12 is adapted to the rectangular hole to achieve circumferential fixation of the torsion spring 30 and the positioning column 12, so that the torsion spring 30 cannot rotate relative to the positioning column 12 around the central axis a.
[0048] In one embodiment of the present application, see Figure 2 and Figure 3 The earphone body 100 includes a shell 101, a through opening 102 is provided on the peripheral side wall of the shell 101, a first movable opening 16 is provided on the peripheral side wall of the sleeve 10, the first movable opening 16 is communicated with the first inner cavity 14, and is correspondingly communicated with the through opening 102, and one end of the adapter 22 away from the shaft body 21 passes through the first movable opening 16 and the through opening 102 in sequence to extend into the shell 101, and is connected to the inner wall of the shell 101.
[0049] The housing 101 is used to accommodate electronic devices such as speakers, microphones and circuit boards, and the through opening 102 is connected to the internal space of the housing 101. Specifically, the housing 101 includes a first housing 104 and a second housing 105, the first housing 104 is connected to the second housing 105, the through opening 102 is opened on the first housing 104, and the end of the adapter 22 away from the shaft 21 is fixedly connected to the side wall of the first housing 104 facing the second housing 105, for example, the end of the adapter 22 away from the shaft 21 can be connected to the first housing 104 by a screw.
[0050] The first movable opening 16 is arranged on the side of the sleeve 10 facing the shell 101. The circumferential width of the first movable opening 16 along the central axis a is greater than the circumferential width of the adapter 22 along the central axis a, so that the first movable opening 16 can provide a movable space for the adapter 22 when it rotates around the central axis a.
[0051] For further information, see Figure 2 and Figure 4 A first port 18 is provided at one end of the sleeve 10 , and the first port 18 is communicated with the first inner cavity 14 and the first movable port 16 . The adjustment assembly 300 further includes a first cover 40 , and the first cover 40 covers the first port 18 .
[0052] Optionally, the first cover 40 can be clamped in the first port 18, that is, the first cover 40 and the inner wall of the first port 18 are interference fit, or the first cover 40 and the first port 18 are threadedly connected. By connecting the first port 18 with the first inner cavity 14, the shaft body 21 can be installed from the first port 18 to the first inner cavity 14, and when the shaft body 21 is arranged in the first inner cavity 14, the two ends of the shaft body 21 along the central axis a are respectively abutted against the partition 13 and the first cover 40 to prevent the shaft body 21 from shaking up and down along the central axis a. One end of the first movable port 16 passes through one end of the sleeve 10 provided with the first port 18 along the central axis a, and is connected with the first port 18, so that part of the adapter 22 can be installed from the first port 18 to the first movable port 16.
[0053] The first cover 40 is covered on the first port 18 to block the first inner cavity 14 and the first movable opening 16 , thereby limiting the shaft body 21 in the sleeve 10 and limiting the adapter 22 in the first movable opening 16 to prevent the fixing member 20 from detaching from the sleeve 10 .
[0054] In one embodiment of the present application, see Figure 2 and Figure 3 A positioning hole 103 is also provided on the shell 101, and a second movable port 17 is provided on the peripheral side wall of the sleeve 10. The second port 19 is connected with the second inner cavity 15 and the second movable port 17, and is correspondingly connected with the positioning hole 103. One end of the torsion spring 30 passes through the second movable port 17 and is inserted into the positioning hole 103.
[0055] The positioning hole 103 is in communication with the inner space of the housing 101. Specifically, the positioning hole 103 is formed on the first housing 104, and the positioning hole 103 and the through opening 102 are spaced apart along the central axis a.
[0056] The second movable opening 17 is arranged on the side of the sleeve 10 facing the shell 101, and the second movable opening 17 and the first movable opening 16 are spaced apart along the central axis a. The circumferential width of the second movable opening 17 along the central axis a is greater than the diameter of the torsion spring 30, so that the second movable opening 17 can provide a movable space for the torsion spring 30 when it rotates around the central axis a.
[0057] By passing one end of the torsion spring 30 through the second movable opening 17, one end of the torsion spring 30 is extended to the outside of the sleeve 10, and by inserting one end of the torsion spring 30 into the positioning hole 103, one end of the torsion spring 30 is connected to the shell 101. In this way, when the shell 101 rotates relative to the sleeve 10 when subjected to external force, one end of the torsion spring 30 produces elastic deformation. After the external force is removed, the torsion spring 30 provides a restoring force for the earphone body 100, so that the earphone body 100 can return to its original position.
[0058] For further information, see Figure 2 , Figure 4 and Figure 6 The other end of the sleeve 10 is provided with a second port 19 , which is communicated with the second inner cavity 15 . The adjustment assembly 300 further includes a second cover 50 , which covers the second port 19 .
[0059] Optionally, the second cover 50 can be clamped in the second port 19, that is, the second cover 50 is interference-fitted with the inner wall of the second port 19, or the second cover 50 is threadedly connected with the second port 19. By connecting the second port 19 with the second inner cavity 15, the torsion spring 30 can be installed in the second inner cavity 15 from the second port 19, and when the torsion spring 30 is arranged in the second inner cavity 15, the two ends of the torsion spring 30 along the central axis a are respectively in contact with the partition 13 and the second cover 50 to prevent the torsion spring 30 from shaking up and down along the central axis a.
[0060] The second cover 50 is covered on the second port 19 to block the second inner cavity 15 , thereby limiting the torsion spring 30 in the second inner cavity 15 and preventing the torsion spring 30 from being separated from the sleeve 10 .
[0061] In one embodiment of the present application, see Figure 4 and Figure 5 One of the first mating surface 202 and the second mating surface 11 is provided with a guide strip 203, and the other is provided with a guide groove 111, and the guide strip 203 and the guide groove 111 are slidably matched along the central axis a.
[0062] Optionally, a guide strip 203 is provided on the first mating surface 202 , and a guide groove 111 is provided on the side wall of the second mating surface 11 ; or, a guide groove 111 is provided on the first mating surface 202 , and a guide strip 203 is provided on the side wall of the second mating surface 11 .
[0063] One end of the guide groove 111 passes through one end of the sleeve 10 provided with the first port 18 , and the guide bar 203 slides into the guide groove 111 from one end of the guide groove 111 , and the first cover 40 blocks one end of the guide groove 111 to prevent the guide bar 203 from escaping from the guide groove 111 .
[0064] The above technical scheme, by slidingly fitting the guide strip 203 with the guide groove 111 along the central axis a, enables the guide strip 203 to slide relative to the guide groove 111 when the sleeve 10 moves along the central axis a, so as to guide the sliding of the sleeve 10, which is beneficial to improving the sliding stability of the sleeve 10. At the same time, the guide strip 203 and the guide groove 111 are fixedly fitted along the circumferential direction of the central axis a, so that the sleeve 10 and the connecting end 201 are clamped in the circumferential direction of the central axis a, and the relative rotation between the sleeve 10 and the connecting end 201 is restricted, so that the sleeve 10 can only slide relative to the connecting end 201 along the central axis a, and cannot rotate relative to the connecting end 201 around the central axis a.
[0065] Optionally, one of the first mating surface 202 and the second mating surface 11 is a concave arc surface, and the other is a convex arc surface, the number of guide strips 203 is multiple, and the multiple guide strips 203 are arranged at intervals around the central axis a, the number of guide grooves 111 is the same as the number of guide strips 203, and the multiple guide grooves 111 are arranged at intervals around the central axis a, and the multiple guide strips 203 are respectively slidably matched with the multiple guide grooves 111 along the central axis a.
[0066] Optionally, the first mating surface 202 is a concave arc surface, and the second mating surface 11 is a convex arc surface. The concave arc surface surrounds the convex arc surface around the central axis a and slides along the central axis a, that is, the concave arc surface and the convex arc surface can slide relative to each other along the central axis a.
[0067] Of course, the first mating surface 202 may be a convex arc surface, and the second mating surface 11 may be a concave arc surface.
[0068] The guide bar 203 extends along the central axis a in a bar shape, and the guide groove 111 also extends along the central axis a in a bar shape. The guide bar 203 slides into the guide groove 111 along the central axis a. The length of the guide groove 111 along the central axis a is greater than the length of the guide bar 203, so that the guide bar 203 can slide relatively along the central axis a in the guide groove 111. In addition, the opposite sides of the guide bar 203 along the central axis a respectively abut against the opposite side walls of the guide groove 111 along the central axis a, thereby limiting the rotation of the guide bar 203 relative to the guide groove 111 around the central axis a.
[0069] Optionally, the number of guide bars 203 and guide grooves 111 are both two, the two guide bars 203 are spaced apart around the central axis a, the two guide grooves 111 are spaced apart around the central axis a, and the two guide bars 203 are respectively slidably matched with the two guide grooves 111 along the central axis a.
[0070] By setting one of the first mating surface 202 and the second mating surface 11 as a concave arc surface and the other as a convex arc surface, and the concave arc surface surrounds the convex arc surface around the central axis a, multiple guide strips 203 are respectively slidably matched with multiple guide grooves 111 around the central axis a, so as to realize the first mating surface 202 and the second mating surface 11 slidingly matched connection along the central axis a, and at the same time, the guide strip 203 cannot be separated from the guide groove 111 along the radial direction of the central axis a, so as to prevent the sleeve 10 from being separated from the connecting end 201 along the radial direction of the central axis a.
[0071] It should be noted that, in other embodiments, undercuts can be provided on the guide strip 203 and / or the guide groove 111 so that the guide strip 203 and the guide groove 111 are interlocked in the radial direction of the center axis a to prevent the guide sleeve from being separated from the guide groove 111 in the radial direction of the center axis a. For example, the guide strip 203 can be set in a wedge shape and the guide groove 111 can be set in a dovetail groove so that the guide strip 203 and the guide groove 111 can slide together along the center axis a and the guide strip 203 cannot be separated from the guide groove 111 in the radial direction of the center axis a, thereby preventing the sleeve 10 from being separated from the connecting end 201.
[0072] In one embodiment of the present application, see Figure 2 and Figure 4 The adjustment assembly 300 further includes a damping pad 60 , which is disposed between the first mating surface 202 and the second mating surface 11 .
[0073] One side of the damping pad 60 is fixedly attached to the first mating surface 202, for example, one side of the damping pad 60 is glued to the first mating surface 202, and the other side of the damping block opposite to the first mating surface 11 is in frictional contact; or one side of the damping pad 60 is fixedly attached to the second mating surface 11, for example, one side of the damping pad 60 is glued to the second mating surface 11, and the other side of the damping block opposite to the first mating surface 202 is in frictional contact;
[0074] Optionally, the damping pad 60 is a silicone pad or the like.
[0075] By setting a damping pad 60 between the first mating surface 202 and the second mating surface 11, the damping pad 60 is used to increase the damping between the first mating surface 202 and the second mating surface 11, so that the first mating surface 202 and the second mating surface 11 have a preset damping, so that when the sleeve 10 slides relative to the connecting end 201 along the center axis a, the sleeve 10 can be maintained at any position within the adjustment range.
[0076] The second mating surface 11 is recessed into the sleeve 10 to form a recessed portion 112, and the damping pad 60 is disposed in the recessed portion 112. One side of the damping pad 60 is in sliding contact with the first mating surface 202. By disposing the damping pad 60 in the recessed portion 112, when the damping pad 60 is in sliding contact with the first mating surface 202, other parts of the second mating surface 11 can also be in sliding contact with the first mating surface 202.
[0077] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
