[0035] Figure 1 The overall structural diagram of the bone conduction earphone according to the embodiment of the utility model is schematically shown. Figure 2 for Figure 1 Another structural diagram of the bone conduction headset. Figure 1 and 2 As shown, the utility model provides a bone conduction headset. The bone conduction headset in the utility model comprises a headband 10, two earphone bodies 20 and two earplugs 31 units, the two earphone bodies 20 are respectively connected to the two ends of the headband 10, the earphone bodies 20 have a receiving space, the receiving space is provided with a bone conduction unit, the outer side of the earphone body 20 is also provided with a first receiving groove, each earplug 31 unit comprises an earplug 31 and a connecting component 32, each first receiving groove is respectively installed with an earplug 31 and a connecting component 32, the earplug 31 is connected to the connecting component 32 and can extend out of the first receiving groove.

[0036] According to the technical solution of the present invention, the two ends of the headband 10 are respectively connected to the earphone body 20, and each earphone body 20 is provided with a bone conduction unit, which can facilitate the user to obtain sound through the bone conduction unit. At the same time, each first receiving groove is also provided with an earplug 31 unit, and the earplug 31 of the earplug 31 unit is connected to the connecting component 32 and can be extended out of the first receiving groove. The bone conduction earphone in the present invention can realize different sound acquisition modes through the earplug 31 unit. In a noisy environment, it can be switched to the earplug 31 mode, that is, the earplug 31 is extended and placed in the ear of the user, thereby reducing sound leakage and improving sound quality and experience. In a quiet environment, the earplug 31 can be placed in the first receiving groove to obtain sound through the bone conduction unit.

[0037] In some embodiments of the present invention, Figure 5 and 6As shown, the connection assembly 32 includes a connection line, a connection member 324, a cover 321 and a base 322. The cover 321 and the base 322 are respectively connected to opposite ends of the connection member 324. A connection line is wound around the outside of the connection member 324. One end of the connection line is elastically connected to the connection member 324, and the other end of the connection line is connected to the earplug 31. In this embodiment, the connection member 324 is wound around the outside of the connection member 324, and the two ends of the connection member 324 are respectively connected to the connection member 324 and the earplug 31. When the earplug 31 located in the first receiving groove is pulled out by the user, the connection line will be driven to move together until the earplug 31 is placed in the ear of the user. The clamping force of the earplug 31 in the ear is much greater than the elastic force of the connection line and the connection member 324, so that the earplug 31 can always be worn inside the ear. The cover 321 and the base 322 are respectively located on opposite sides of the connecting line, which can limit the connecting line on both sides along the axis direction of the connecting member 324 to ensure that the connecting member 324 will not move in other directions when being pulled out by the earplug 31.

[0038] Specifically, in this embodiment, when the user does not need the earplug 31, he only needs to take the earplug 31 out of the ear. Due to the elastic connection between the connecting wire and the connecting member 324, the earplug 31 can be retracted back into the first receiving groove, thereby realizing the storage operation.

[0039] Specifically, in this embodiment, a battery unit is also provided in the accommodating space, and the battery unit is electrically connected to the earplug 31 unit and the bone conduction unit, respectively, and can supply power to the bone conduction unit and the earplug 31 unit. Among them, the earplug 31 of the earplug 31 unit is an in-ear earphone structure, and the earplug 31 can be electrically connected to the battery unit through a connecting line, thereby realizing power supply.

[0040] In some embodiments of the present invention, Figure 6 As shown, the connecting component 32 also includes a first elastic member 326 and a turntable 323. The turntable 323 can be rotatably mounted on the outside of the connecting member 324 along its own axial direction and is located between the cover body 321 and the base 322. The turntable 323 has a storage cavity. The first elastic member 326 is located in the storage cavity and is mounted on the outside of the connecting member 324. One end of the first elastic member 326 is connected to the connecting member 324, and the other end of the first elastic member 326 is connected to the turntable 323. The connecting wire is wound around the outside of the turntable 323, one end of the connecting wire is connected to the connecting member 324 through the turntable 323 and the first elastic member 326 respectively, and the other end of the connecting wire is connected to the earplug 31. In this embodiment, the first elastic member 326 is a coil spring, which is located in the storage cavity and is sleeved outside the connecting member 324. The first end of the coil spring is fixedly connected to the connecting member 324, and the second end of the coil spring is connected to the turntable 323. When the turntable 323 rotates along its own axial direction, the elastic restoring force can be increased, thereby facilitating the reset of the connecting wire and the earplug 31.

[0041] Specifically, in this embodiment, the connecting wire is wound around the outside of the turntable 323, and one end of the connecting wire is connected to the earplug 31, and the other end of the connecting wire is connected to the turntable 323. At the same time, the connecting wire is electrically connected to the battery unit. When the user takes out the earplug 31, the earplug 31 drives the turntable 323 to rotate through the connecting wire, and then pulls out the connecting wire wound around the turntable 323 until the earplug 31 can reach the position of the user's ear. Similarly, the clamping force of the earplug 31 in the ear is much greater than the elastic force of the coil spring. When the user does not need the earplug 31, he only needs to take the earplug 31 out of the ear. Due to the elastic connection of the coil spring, the earplug 31 can be retracted back into the first receiving groove, thereby realizing the storage operation.

[0042] In some embodiments of the present invention, Figure 5 and 6 As shown, the connection assembly 32 further includes a ball 325, a limiting groove is provided on one side of the cover 321 facing the turntable 323, a track groove 3231 is provided on one side of the turntable 323 facing the cover 321, and the ball 325 rolls with the limiting groove and the track groove 3231 respectively. In this embodiment, the track groove 3231 includes a first annular groove portion and a second annular groove portion, the first annular groove portion is located in the second annular groove portion and is spaced apart from the second annular groove portion, a transition groove portion is connected between the first annular groove portion and the second annular groove portion, and a limiting groove portion is connected between the first annular groove portion and the second annular groove portion, when the earplug 31 and the connecting line are pulled out, the ball 325 rolls in the second annular groove, and when the earplug 31 and the connecting line are retracted to the first receiving groove, the ball 325 slides into the first annular groove through the transition groove portion. When the earplug 31 and the connecting line are pulled out to a certain length and need to be fixed, the ball 325 will slide in the second annular groove to the limit groove part, and because the limit groove part has an inner wall surface along one side of the circumference of the first annular groove or the second annular groove, it can play a shielding role, thereby realizing the segmented contraction function of the connecting line. Finally, the coil spring is used as the power, and the track groove 3231 and the ball 325 on the rotating disk 323 are used as restrictions, so as to achieve the segmented contraction function of the connecting line.

[0043] Specifically, in this embodiment, the limiting groove is a strip groove structure arranged along the radial direction of the first annular groove, which, in conjunction with the combined structure of the upper track groove 3231 and the ball 325, can realize the segmented contraction function of the connecting line.

[0044] In some embodiments of the present invention, the storage cavity has a first opening, and the base 322 is covered on the first opening. In this embodiment, the first opening is convenient for installing and storing the first elastic member 326, and can limit the first elastic member 326 to ensure the elastic restoring force of the first elastic member 326 on the rotating disk 323.

[0045] In some embodiments of the present invention, the connecting assembly 32 further includes a second elastic member, the second elastic member is provided on the outer cover of the connecting member 324, a connecting wire is wound around the outer cover of the second elastic member, a first end of the second elastic member is fixedly connected to the connecting member 324, and a second end of the second elastic member is connected to one end of the connecting member 324. In this embodiment, the second elastic member is a coil spring, which is connected to the earplug 31 through the connecting member 324, and can also realize the function that the earplug 31 can be pulled out by the user and reset by the coil spring when not in use.

[0046] In some embodiments of the present invention, Figure 3 As shown, the first receiving groove includes a first groove body 211 and a second groove body 212, the first groove body 211 is connected to the second groove body 212 and the outside, the earplug 31 is arranged in the first groove body 211, and the connecting component 32 is arranged in the second groove body 212. In this embodiment, the width of the first groove body 211 along the first direction is greater than the width of the second groove body 212 along the first direction, and the first direction is perpendicular to the arrangement direction of the first groove body 211 and the second groove body 212, so that the earphone elastically connected to the connecting component 32 can be clamped in the first groove body 211 without interfering with the connecting component 32 of the second groove body 212. The connecting component 32 is fixed to the second groove body 212, and the arrangement direction of the cover body 321 and the base 322 is perpendicular to the first direction.

[0047] In some embodiments of the present invention, Figure 4 As shown, the bone conduction earphone further includes a pressing component 40, and a second receiving groove 22 is further provided on the outer side of the earphone body 20, and a connecting hole 23 is provided between the second receiving groove 22 and the first receiving groove, and part of the pressing component 40 is provided in the second receiving groove 22, and one end of the pressing component 40 is exposed outside the second receiving groove 22, and the other end of the pressing component 40 passes through the connecting hole 23 and abuts against the earplug 31, and when one end of the pressing component 40 moves toward the second receiving groove 22, the other end of the pressing component 40 can drive the earplug 31 to move toward the side away from the connecting component 32, so that part of the earplug 31 is located outside the first receiving groove. In this embodiment, the earplug 31 is completely disposed in the first receiving groove when it is not taken out, which can improve the aesthetics of the bone conduction earphone with the earplug 31 component. When the user presses one end of the pressing component 40, the other end of the pressing component 40 applies a torque to the earplug 31, and moves the earplug 31 toward the side away from the connecting component 32, so that part of the earplug 31 is located outside the first receiving groove, which makes it easy for the user to take the earplug 31 away. The earplug 31 can then be stretched to place the earplug 31 in the ear.

[0048] In some embodiments of the present invention, Figure 4As shown, the pressing assembly 40 includes a pressing member 41 and a linkage member 42. Part of the pressing member 41 is exposed outside the second accommodating groove 22. One end of the linkage member 42 is connected to the pressing member 41, and the other end of the linkage member 42 passes through the connecting hole 23 and abuts against the side of the earplug 31 facing the connecting assembly 32. In this embodiment, the pressing member 41 is partially located outside the second receiving groove 22, which is convenient for the user to press the pressing member 41. The linkage member 42 is a rod-shaped structure. One end of the linkage member 42 is connected to one end of the pressing member 41 away from the slot of the second receiving groove 22, and the other end of the linkage member 42 is abutted against the side of the earplug 31 toward the connecting component 32. When the user presses the pressing member 41, the end of the pressing member 41 away from the slot of the second receiving groove 22 can press against one end of the linkage member 42, so that the linkage member 42 rotates with the connection point between the linkage member 42 and the connecting hole 23 as the fulcrum, and the other end of the linkage member 42 pushes the earplug 31 toward the side away from the connecting component 32, which is convenient for the user to take it.

[0049] Specifically, in this embodiment, the aperture of the connecting hole 23 is larger than the diameter of the linkage member 42, which can facilitate the tilting of the linkage member 42. When the pressing member 41 presses one end of the linkage member 42, the linkage member 42 can rotate in the connecting hole 23, thereby allowing the other end of the linkage member 42 to push the earplug 31.

[0050] In some embodiments of the utility model, the side of the linkage member 42 facing away from the pressing member 41 is elastically connected to the bottom of the second receiving groove 22. In this embodiment, the above arrangement enables the linkage member 42 and the pressing member 41 to have a first position and a second position. When in the first position, part of the pressing member 41 is located outside the second receiving groove 22, and the earplug 31 is located in the first receiving groove. When in the second position, the pressing member 41 is located in the second receiving groove 22, and part of the earplug 31 is exposed outside the first receiving groove. The first position and the second position can be switched by the linkage member 42 and the spring at the bottom of the second receiving groove 22.

[0051] Furthermore, in this embodiment, the use process of the bone conduction earphone is as follows: when in a quiet environment, the user can directly use the bone conduction unit to receive sound, which can avoid fatigue caused by long-term use, and does not block the ear canal, and retains external sound while listening. When in a noisy environment, the user can press the pressing member 41 to drive the linkage member 42 to lift the earplug 31, so that part of the earplug 31 is located outside the first receiving groove, which is convenient for the user to take and stretch the earplug 31. When the earplug 31 is stretched, the connecting wire wrapped outside the turntable 323 will drive the turntable 323 to rotate. During the rotation process, the cooperation of the ball 325, the track groove 3231 and the limit groove can realize the function of the extension and segmented stop of the connecting wire until the earplug 31 matches the ear of the user. When the earplug 31 is not in use, the earplug 31 is directly pulled out to the longest length, and then retracted, so that the earplug 31 can be retracted into the first receiving groove again.

[0052] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
