[0025] Please refer to Figures 1 to 8 As shown, the present invention provides a headset 100, which includes a headband 1, a locking device 2 and a sounding device 3. The locking device 2 includes a mounting seat 21, a first linkage block 22 and a second linkage block 23. The mounting seat 21 is arranged on the headband 1, and the first linkage block 22 and the second linkage block 23 are both elastically connected to the mounting seat 21, and the first linkage block 22 abuts against the second linkage block 23; the sounding device 3 is transmission-connected to the second linkage block 23, and the sounding device 3 is provided with a push rod 33; wherein the headset 100 has an unlocked state and a locked state. In the unlocked state, the push rod 33 can push the first linkage block 22 to move, so that the mounting seat 21 forms an avoidance space, the first linkage block 22 can extend into and be limited in the avoidance space, and at the same time drive the sounding device 3 to flip relative to the headband 1; in the locked state, the sounding device 3 drives the second linkage block 23 away from the avoidance space, and the first linkage block 22 is reset and abuts against the second linkage block 23.

[0026] In this embodiment, the headset 100 includes but is not limited to an earmuff structure and a headband connecting structure for connecting the earmuff structure and wearing, wherein the earmuff structure includes but is not limited to a shell 31, ear pads, circuit boards, speakers, decoders, power supply systems, etc., and the earmuff structure can be a circum-ear structure that completely wraps the ear, or it can be an ear-pressing structure that only covers a partial area of ​​the ear, which is not limited here. At the same time, the headband connecting structure can also be folded, retracted, rotated, etc., so as to adjust the earmuff structure to adapt to the personalized wearing of different people or convenient carrying and storage, etc.

[0027] In this embodiment, if Figure 1 and Figure 2 As shown, the headband 1 is the above-mentioned head beam connecting structure, and a locking device 2 and a sound-emitting device 3 connected to the locking device 2 are provided at both ends of the headband 1, wherein the headband 1 is arranged in a ring shape and has a notch, the locking device 2 is connected to the two ends of the headband 1 located at the notch, and the sound-emitting device 3 is connected to the locking device 2, so as to facilitate the user to wear; the sound-emitting device 3 is the above-mentioned earmuff structure, which includes but is not limited to the above-mentioned shell 31, ear pads, circuit boards, speakers, decoders, power supply systems, etc.

[0028] In this embodiment, if Figures 3 to 6 As shown, the locking device 2 includes a mounting seat 21, a first linkage block 22 and a second linkage block 23. The mounting seat 21 is movably connected to the headband 1, such as the mounting seat 21 is rotated (flipped) and connected to the end of the headband 1, and / or can be slidably connected to the end or body of the headband 1, etc. The mounting seat 21 can be a structure such as a seat body, a frame body or a platform body. At the same time, the mounting seat 21 can form a structure such as a mounting cavity, a mounting space, a mounting groove, a mounting hole, etc., so that the first linkage block 22 and the second linkage block 23 can be movably arranged in the mounting seat 21, such as being movably arranged in the mounting cavity or the mounting groove, at one end where the first linkage block 22 and the second linkage block 23 are connected to the mounting seat 21, the first linkage block 22 and the second linkage block 23 are both elastically connected to the mounting seat 21, and at the same time, the first linkage block 22 and the second linkage block 23 are movably abutted against each other, so that the first linkage block 22 and the second linkage block 23 can be moved or reset relative to the mounting seat 21 under the action of elastic force, or produce relative movement.

[0029] Based on the above embodiments, it can be further known that the sound-generating device 3 is transmission-connected to the second linkage block 23, such as the sound-generating device 3 is rotationally connected to the second linkage block 23, or the sound-generating device 3 can rotate relative to the second linkage block 23, etc. If the headset 100 also includes a crank, the second linkage block 23 is slidably arranged on the mounting seat 21, one end of the crank is connected to the sound-generating device 3, and the other end of the crank is connected to the slider, so that when the sound-generating device 3 rotates relative to the headband 1, it can also synchronously drive the second linkage block 23 to slide along a straight line relative to the mounting seat, or, the sound-generating device 3 is provided with a spiral guide groove, and part of the second linkage block 23 is slidingly arranged in the spiral guide groove, and when the sound-generating device 3 rotates relative to the headband 1, the second linkage block 23 can also move in a straight line along the spiral guide groove, which is not limited here. Therefore, the headset 100 has a use state in which the two sound-emitting devices 3 are arranged opposite to and at intervals at the two ends of the headband 1, and a flipped state in which the two sound-emitting devices 3 are flipped (rotated) at a certain angle relative to the headband 1. At the same time, the sound-emitting device 3 is provided with a push rod 33. In the use state, the push rod 33 abuts against the first linkage block 22, and the push rod 33 abuts against the side of the first linkage block 22 that is away from the elastic connection with the mounting seat 21, so that the first linkage block 22 can be pushed to move relative to the mounting seat 21 through the push rod 33.

[0030] It can be understood that, in the use state, the top rod 33 abuts the first linkage block 22, and the first linkage block 22 abuts the second linkage block 23. When the headset 100 enters the unlocked state, the top rod 33 pushes the first linkage block 22 to move relative to the mounting seat 21, the position of the first linkage block 22 changes, and the mounting seat 21 forms an avoidance space on the side of the first linkage block 22 facing the top rod 33, and the second linkage block 23 abutting the first linkage block 22 extends into the avoidance space under the action of elastic force. At the same time, the sound-emitting device 3 movably connected to the second linkage block 23 is flipped relative to the headband 1. At this time, the first linkage block 22 is disengaged from the abutment with the top rod 33, and the first linkage block 22 abuts the second linkage block 23 located in the avoidance space again under the action of elastic force. At this time, the second linkage block 23 is limited in the avoidance space, and at the same time, the position of the sound-emitting device 3 relative to the second linkage block 23 and the position relative to the headband 1 remain fixed, and the headset 100 is in a flipped state.

[0031] When returning to the use state from the flipped state, the headset 100 enters the locked state. In the locked state, the sound-generating device 3 is rotated so that the sound-generating device 3 drives the second linkage block 23 to move away from the avoidance space. At this time, the first linkage block 22 is reset under the action of elastic force and re-contacts the second linkage block 23, so that the headset 100 is locked to the use state.

[0032] It can be understood that, through the abutment of the top rod 33 on the first linkage block 22, the movement of the first linkage block 22 can be realized, and the second linkage block 23 can be driven to move relative to the first linkage block 22, so that the sound-emitting device 3 can be flipped relative to the headband 1 through the second linkage block 23, and after the sound-emitting device 3 is flipped to a certain angle, the first linkage block 22 can limit the abutment against the second linkage block 23, and limit the second linkage block 23 to the avoidance space, thereby keeping the position of the sound-emitting device 3 fixed relative to the headband 1, avoiding the shaking of the sound-emitting device 3 after flipping, and improving the overall wearing stability and comfort of the headset 100.

[0033] The headset 100 of the technical solution comprises a headband 1, a locking device 2 and a sounding device 3, wherein the locking device 2 comprises a mounting seat 21, a first linkage block 22 and a second linkage block 23, the mounting seat 21 is arranged on the headband 1, the first linkage block 22 and the second linkage block 23 are elastically connected to the mounting seat 21, and the first linkage block 22 abuts against the second linkage block 23; the sounding device 3 is movably connected to the second linkage block 23, and the sounding device 3 is provided with a push rod 33; the headset 100 has an unlocked state and a locked state, in the unlocked state, The push rod 33 can push the first linkage block 22 to move so that the mounting seat 21 forms an escape space. The first linkage block 22 can extend into and be limited in the escape space, and at the same time drive the sound-emitting device 3 to flip relative to the headband 1; in the locked state, the sound-emitting device 3 drives the second linkage block 23 away from the escape space, and the first linkage block 22 is reset and abuts against the second linkage block 23, thereby keeping the position of the sound-emitting device 3 fixed relative to the headband 1, avoiding the sound-emitting device 3 from shaking after flipping, and improving the overall wearing stability and comfort of the headset 100.

[0034] In one embodiment, if Figures 3 to 8 As shown, the sound-generating device 3 includes a shell 31 and a pressing panel 32 . The shell 31 is rotatably connected to the mounting seat 21 ; the pressing panel 32 is connected to the top rod 33 , and both the top rod 33 and the pressing panel 32 are movably arranged on the shell 31 .

[0035] In this embodiment, the shell 31 is the main supporting structure of the sound-emitting device 3. A cavity is formed inside the shell 31 to install components such as a circuit board, a speaker, and a power supply device. At the same time, the shell 31 is rotatably connected to the mounting seat 21, and is also transmission-connected to the second linkage block 23. For example, the second linkage block 23 and the shell 31 are driven by a synchronous belt, or by a gear transmission, so that when the second linkage block 23 moves relative to the first linkage block 22, the shell 31 can be driven to rotate relative to the mounting seat 21 and the headband 1. Specifically, a first synchronous wheel is provided on the second linkage block 23, a second synchronous wheel is provided on the shell 31, and a synchronous belt is provided to be wound around the outer walls of the first synchronous wheel and the second synchronous wheel to realize the transmission connection between the second linkage block 23 and the shell 31; or, a first gear is provided on the second linkage block 23, and a second gear is provided on the shell 31, and the transmission connection between the second linkage block 23 and the shell 31 is realized by the transmission meshing of the first gear and the second gear.

[0036] Based on the above embodiments, further, the sound-emitting device 3 also includes a pressing panel 32, which is movably arranged on the shell 31, such as the pressing panel 32 is slidably arranged on the shell 31 or is elastically connected to the shell 31. At the same time, the pressing panel 32 is connected to the top rod 33, and the top rod 33 can also be movably arranged relative to the shell 31.

[0037] It can be understood that the pressing panel 32 is a plate-like structure, which is connected to the top rod 33 through the pressing panel 32. When the user presses or pushes the pressing panel 32, the pressing panel 32 and the top rod 33 move relative to the shell 31. At the same time, the top rod 33 pushes the first linkage block 22 to move the first linkage block 22 relative to the mounting seat 21 and make the second linkage block 23 enter the avoidance space. At this time, the shell 31 transmission-connected to the second linkage block 23 rotates (flips) synchronously to realize the change of the overall position of the sound-emitting device 3 and the change of the state of the headset 100 (i.e., entering the flip state).

[0038] It can be understood that by setting the pressing panel 32, the pressing area for user operation can be increased, and by pressing the pressing panel 32, the relative positions of the first linkage block 22 and the second linkage block 23 can be changed, thereby realizing the change of the state of the headset 100, making it easier for users to use and improving the convenience of use.

[0039] In one embodiment, if Figures 3 to 6 As shown, the sound-generating device 3 also includes an abutment wheel 34, which is connected to the shell 31, and an arc tooth surface 341 is provided on the side of the abutment wheel 34 facing the second linkage block 23; a vertical tooth surface 231 is provided on the side of the second linkage block 23 facing the arc tooth surface 341, and the arc tooth surface 341 and the vertical tooth surface 231 are meshed with each other.

[0040] In this embodiment, the abutment wheel 34 is a wheel body structure with a circular axial cross-section. The abutment wheel 34 is fixedly connected to the shell 31 so that the position of the abutment wheel 34 relative to the shell 31 remains fixed. The abutment wheel 34 is provided with an arc tooth surface 341 on the side facing the second linkage block 23, wherein the arc tooth surface 341 is an arc-shaped tooth surface arranged on the surface of the abutment wheel 34, and a plurality of parallel and spaced teeth are arranged on the arc tooth surface 341. The vertical tooth surface 231 is a tooth surface arranged on a side plane of the second linkage block 23 facing the abutment wheel 34, and a plurality of parallel and spaced teeth are arranged on it. The arc tooth surface 341 and the vertical tooth surface 231 are meshed with each other.

[0041] It can be understood that the transmission connection between the abutment wheel 34 and the second linkage block 23 is achieved through the mutual engagement of the arc tooth surface 341 and the vertical tooth surface 231. In the process of entering the flipping state from the use state, the second linkage block 23 moves relative to the first linkage block 22 and enters the avoidance space. At this time, the position of the vertical tooth surface 231 changes together, and at the same time, the abutment wheel 34 and the shell 31 connected to the abutment wheel 34 are driven to rotate through the engagement with the arc tooth surface 341, thereby realizing the flipping of the sound-emitting device 3 and the change of the state of the headset 100.

[0042] It can be understood that by setting the arc tooth surface 341 and the vertical tooth surface 231, the linear motion of the second linkage block 23 can be converted into the rotational motion of the abutment wheel 34 and the shell 31, thereby effectively realizing the flipping of the sound-emitting device 3. At the same time, the transmission connection structure between the second linkage block 23 and the shell 31 can also be made more compact, thereby reducing the overall structure of the locking device 2 and the sound-emitting device 3, and reducing the overall space occupancy. After the second linkage block 23 is limited to the avoidance space, due to the meshing relationship between the arc tooth surface 341 and the vertical tooth surface 231, it can also ensure that the sound-emitting device 3 is always in a flipped state without shaking, so as to ensure the fixed position of the sound-emitting device 3 and effectively improve the overall wearing comfort and stability.

[0043] In one embodiment, if Figures 3 to 5 As shown, the sound-generating device 3 also includes a plurality of first elastic members 35, which are arranged at intervals on the shell 31 and connected to the pressing panel 32; the direction in which the pressing panel 32 compresses the first elastic member 35 is consistent with the direction in which the top rod 33 pushes against the first linkage block 22; the shell 31 is provided with a giveway groove 311, the first elastic member 35 is arranged on the bottom wall of the giveway groove 311, and the notch of the giveway groove 311 is provided with a limiting boss 312; the pressing panel 32 is arranged in the giveway groove 311 and covers the notch of the giveway groove 311, and the first elastic member 35 pushes against the pressing panel 32 to abut against the limiting boss 312.

[0044] In this embodiment, the shell 31 is provided with a giveway groove 311, and the groove of the giveway groove 311 is set on the side facing away from the headband 1. The multiple first elastic members 35 are all compression springs. The multiple first elastic members 35 are arranged on the bottom wall of the giveway groove 311. For example, a positioning groove connecting the giveway groove 311 is provided on the bottom wall of the giveway groove 311, and one end of the first elastic member 35 is limitedly set in the positioning groove. At the same time, the first elastic member 35 is extended and retracted along the groove depth direction of the giveway groove 311.

[0045] At the same time, a limiting boss 312 is provided at the notch of the give way groove 311. The limiting boss 312 is arranged in a ring shape around the notch of the give way groove 311 and covers part of the notch of the give way groove 311. The pressing panel 32 is arranged at the notch of the give way groove 311 and covers the notch of the give way groove 311. At the same time, the first elastic member 35 pushes against the pressing panel 32 at one end away from the one connected to the give way groove 311, and makes the edge of the pressing panel 32 on the side facing away from the first elastic member 35 abut against the limiting boss 312, so that the pressing panel 32 is movably arranged in the give way groove 311 of the shell 31.

[0046] The first elastic member 35 is provided to allow the user to move the pressing panel 32 in a direction opposite to the shell 31 without causing any deviation therefrom, thereby ensuring the stability and comfort of the user during use. At the same time, by providing the first elastic member 35, the pressing panel 32 can rebound quickly after the pressing panel 32 is pressed, thereby driving the push rod 33 to rebound together with the pressing panel 32, so that the push rod 33 is separated from the abutment with the first linkage block 22, and the second linkage block 23 enters the avoidance space and abuts against the first linkage block 22, thereby limiting the position of the second linkage block 23 so that the sound-generating device 3 is in a flipped state and remains fixed relative to the headband 1.

[0047] In one embodiment, if Figure 7 and Figure 8 As shown, the top rod 33 includes a cross rod 331 and two longitudinal rods 332. The two longitudinal rods 332 are arranged at both ends of the cross rod 331, and the extension direction of the rod body of the longitudinal rod 332 is perpendicular to the extension direction of the rod body of the cross rod 331; the shell 31 is also provided with a limiting groove 313 connected to the yield groove 311, the cross rod 331 is movably arranged in the limiting groove 313, and is connected to the pressing panel 32, and the end of the longitudinal rod 332 away from the cross rod 331 abuts against the first linkage block 22.

[0048] In this embodiment, the rod extension direction of the longitudinal rod 332 is consistent with the movement direction of the top rod 33 pushing the first linkage block 22, and is also consistent with the direction in which the pressing panel 32 squeezes the first elastic member 35 to drive the top rod 33 to move. The rod extension direction of the cross rod 331 is perpendicular to the rod extension direction of the longitudinal rod 332, and the two longitudinal rods 332 are arranged at both ends of the cross rod 331 along the rod extension direction. A limiting groove 313 connected to the give way groove 311 is also provided on the shell 31. The two side walls of the limiting groove 313 are relatively spaced along the rod extension direction of the longitudinal rod 332. Part of the rod body of the cross rod 331 is movably arranged in the limiting groove 313, and at the same time, part of the rod body of the cross rod 331 is located in the give way groove 311 to be connected with the pressing panel 32.

[0049] It can be understood that the cross bar 331 is used to connect the two longitudinal bars 332 and the pressing panel 32, and the longitudinal bar 332 is abutted against the first linkage block 22 away from the end connected to the cross bar 331. By arranging two longitudinal bars 332 along the extension direction of the rod body of the cross bar 331, the abutment area between the top rod 33 and the first linkage block 22 can be increased, and the top rod 33 can be ensured to maintain balance when pushing against the first linkage block 22, thereby avoiding the first linkage block 22 from being deflected during the movement and failing to make the second linkage block 23 enter the avoidance space, thereby improving the fault tolerance during the pressing and flipping process. At the same time, the limit groove 313 can also The cross bar 331 movably arranged therein limits the range of movement, that is, the maximum range of movement of the cross bar 331 is between the two side walls of the limiting groove 313 along the extension direction of the rod body of the longitudinal rod 332, so as to ensure that the first linkage block 22 can be pushed to move a sufficient distance to allow the second linkage block 23 to enter the avoidance space. In the use state, due to the action of the elastic force, the first linkage block 22 is always in contact with the top rod 33. At this time, the position of the first linkage block 22 can be limited by the limitation of the side wall of the limiting groove 313, and the relative position of the first linkage block 22 and the second linkage block 23 in the locking device 2 can be fixed.

[0050] In one embodiment, along the rod extension direction of the longitudinal rod 332, the width of the limiting groove 313 is greater than or equal to the width of the abutment between the second linkage block 23 and the first linkage block 22; it can be understood that the width of the limiting groove 313 along the rod extension direction of the longitudinal rod 332, that is, the distance between the two side walls of the limiting groove 313, must be greater than or equal to the width of the abutment between the second linkage block 23 and the first linkage block 22, so that in the process of the cross bar 331 moving along the limiting groove 313, when the cross bar 331 abuts against the side wall of the limiting groove 313 adjacent to the first linkage block 22, it can completely push the first linkage block 22 to move and make the first linkage block 22 and the second linkage block 23 disengage from each other, thereby ensuring that the second linkage block 23 can accurately enter the avoidance space.

[0051] Optionally, the movement direction of the push rod 33 pushing the first linkage block 22 is perpendicular to the movement direction of the second linkage block 23. It can be understood that the movement direction of the first linkage block 22 and the movement direction of the second linkage block 23 are perpendicular to each other, so that the second linkage block 23 and the longitudinal rod 332 abut against different side walls of the first linkage block 22, so that the movement of the push rod 33 pushing against the first linkage block 22 and the movement of the second linkage block 23 and the first linkage block 22 abutting against each other do not produce motion interference, but still retain the linkage motion relationship through the first linkage block 22, that is, the push rod 33 pushes against the first linkage block 22 to move in one direction, and in another direction perpendicular to the direction, the second linkage block 23 can enter or leave the avoidance space to achieve the flipping, locking and resetting of the sound-generating device 3.

[0052] In one embodiment, if Figures 3 to 6 As shown, the locking device 2 also includes a second elastic member 24 and a third elastic member 25, the two ends of the second elastic member 24 are respectively connected to the mounting seat 21 and the first linkage block 22, and the two ends of the third elastic member 25 are respectively connected to the mounting seat 21 and the second linkage block 23; the elastic expansion and contraction direction of the second elastic member 24 is perpendicular to the elastic expansion and contraction direction of the third elastic member 25.

[0053] It can be understood that the second elastic member 24 and the third elastic member 25 have the same structure, wherein one end of the second elastic member 24 is connected to the mounting seat 21, the other end of the second elastic member 24 is connected to the first linkage block 22, and the second elastic member 24 is connected to the side of the first linkage block 22 that is away from the top rod 33, and the telescopic direction of the second elastic member 24 is the same as the extension direction of the rod body of the longitudinal rod 332, and the elastic telescopic direction of the third elastic member 25 is perpendicular to the elastic telescopic direction of the second elastic member 24, so that the second linkage block 23 moves along the movement direction perpendicular to the top rod 33 to push against the first linkage block 22, so as to enter or move away from the avoidance space, and realize the flipping, locking and resetting of the sound-emitting device 3.

[0054] In one embodiment, if Figures 4 to 6 As shown, the first linkage block 22 includes a first side surface 221 facing the second linkage block 23, and a second side surface 222 facing the push rod 33, and the second elastic member 24 is connected to the side of the first linkage block 22 facing away from the second side surface 222; when the push rod 33 abuts against the second side surface 222, the second linkage block 23 abuts against the first side surface 221, and the push rod 33 pushes the first linkage block 22 to move, so that when the second linkage block 23 extends into the avoidance space, the second linkage block 23 abuts against the second side surface 222.

[0055] It can be understood that the plane where the first side surface 221 is located and the plane where the second side surface 222 is located are set at an angle or perpendicular to each other. When in use, the top rod 33 abuts against the second side surface 222, and the second linkage block 23 abuts against the first side surface 221. At this time, the relative positions of the sound-emitting device 3, the first linkage block 22 and the second linkage block 23 remain fixed, and the position of the sound-emitting device 3 relative to the headband 1 remains fixed. In the flipping state, the top rod 33 pushes the first linkage block 22 to move, and the second linkage block 23 extends into the avoidance space. At this time, the second linkage block 23 extending into the avoidance space abuts against the second side surface 222 of the first linkage block 22, so as to limit the position of the second linkage block 23 through the first linkage block 22. At the same time, the second linkage block 23 can also limit the position of the first linkage block 22, so that the sound-emitting device 3, the first linkage block 22 and the second linkage block 23 remain fixed after flipping, so as to effectively position the sound-emitting device 3 after flipping, thereby improving the stability and comfort of the earphone during wearing and use.

[0058] The mounting seat 21 is provided with a first opening 212 and a second opening 213 on the side facing the sound-emitting device 3. The first opening 212 and the second opening 213 are communicated with each other and are also communicated with the accommodating cavity 211, wherein the first linkage block 22 is movably provided at the first opening 212, and the second linkage block 23 is movably provided at the second opening 213, and at the same time, a part of the structure of the first linkage block 22 protrudes from the first opening 212 to abut against the top rod 33, and a part of the structure of the second linkage block 23 protrudes from the second opening 213 to be connected with the abutment wheel 34 through tooth surface transmission.

[0059] It can be understood that by setting up the accommodating cavity 211, it is possible to provide a movable space for the first linkage block 22 and the second linkage block 23, so that the first linkage block 22 and the second linkage block 23 can generate movement relative to the mounting seat 21. At the same time, a first opening 212 and a second opening 213 connected to the accommodating cavity 211 are opened on the mounting seat 21, so that the first linkage block 22 and the second linkage block 23 can be abutted or connected with the sound-emitting device 3.
