[0008] In this invention, two headbands are connected to the left and right sides of a headband positioning component, one on the left and one on the right. The headband positioning component connects the two headbands together, and the left and right headbands are respectively connected to the left and right sound units. The upper ends of the left and right headbands pass through the left and right sliding channels of a guide member. The left headband engages with the elastic positioning element in the left sliding channel, meaning the elastic positioning element in the left sliding channel positions the left headband; similarly, the right headband engages with the elastic positioning element in the right sliding channel, meaning the elastic positioning element in the right sliding channel positions the right headband. By moving the headbands left and right, their lateral positions can be adjusted, thereby adjusting the distance between the left and right sound units and changing the clamping force on the user's head, allowing the headphones to adapt to users with different head shapes. Once the lateral positions of the headbands are adjusted and a positioning part of the headband engages with the elastic positioning element, the headband position is fixed, reducing the risk of the headbands sliding freely relative to the headband positioning component and changing position. The headband unit of this invention splits a traditional complete headband into two headbands and uses a headband positioning component to adjust the left and right distance between the two headbands, thereby changing their clamping force. The structure is simple.

[0009] According to some embodiments of the present invention, the sliding channel includes a groove area and an installation area. The groove area extends through the end of the guide member. The installation area and the groove area are arranged in a direction perpendicular to the left and right direction.

[0015] According to some embodiments of this utility model, the side of the positioning protrusion closest to the headband has an arc-shaped structure.

[0016] According to some embodiments of this utility model, the two sliding channels are separated.

[0017] The headphones according to a second aspect of the present invention include the headband unit described above.

[0018] The over-ear headphones according to the embodiments of the present invention have at least the following beneficial effects:

[0019] In this invention, two headbands are connected to the left and right sides of a headband positioning component, which connects the two headbands together. Each headband connects to a left or right sound-producing unit. The upper ends of the two headbands pass through the left and right sliding channels of a guide member. The left headband engages with an elastic positioning member in the left sliding channel, positioning the left headband; similarly, the right headband engages with an elastic positioning member in the right sliding channel, positioning the right headband. By moving the headbands left and right, their positions can be adjusted, thereby adjusting the distance between the left and right sound-producing units and changing the clamping force on the user's head, thus adapting the headphones to different head shapes. Once the left and right positions of the headbands are adjusted and a positioning part of the headband engages with the elastic positioning member, the headband position is secured, reducing the risk of the headbands sliding freely relative to the positioning component and changing their position. The headband unit of this invention splits a traditional complete headband into two headbands and uses a headband positioning component to adjust the left and right distance between the two headbands, thereby changing their clamping force. The structure is simple.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] like Figure 1 As shown in the figure, an embodiment of the present invention provides a headset, which can be a smart headset and can be configured with call noise reduction function and / or artificial intelligence noise reduction function; at the same time, it can also be configured with stereo surround sound and other functions.

[0038] like Figure 1 As shown, the headphones include a headband unit 100 and a sound-generating unit 200 connected to the headband unit 100.

[0039] It should be noted that there are two sound-emitting units 200, which are respectively connected to the left and right ends of the headband unit 100. The headband unit 100 can be worn on the user's head, with the two sound-emitting units 200 facing the user's ears respectively. Each sound-emitting unit 200 contains a speaker for emitting sound. In some other embodiments, the sound-emitting unit 200 may also contain a microphone for receiving sound signals.

[0040] like Figure 1 As shown, the headband unit 100 includes a headband positioning component 110 and two headbands 120, which are respectively connected to the left and right ends of the headband positioning component 110.

[0041] Understandably, the two headbands 120 are connected to the left and right sides of the headband positioning assembly 110, which is used to connect the two headbands 120 together. The left and right headbands 120 are respectively connected to the left and right sound units 200.

[0042] like Figures 2 to 5 As shown, the headband positioning assembly 110 includes a guide 111. The guide 111 has two sliding channels 1113 inside. The two sliding channels 1113 pass through the left and right ends of the guide 111 respectively. It should be noted that the two sliding channels 1113 are arranged on the guide 111, one on the left and one on the right, and the two sliding channels 1113 pass through the left and right ends of the guide 111 respectively.

[0043] The two sliding channels 1113 can be interconnected and form a whole, or they can be separated from each other. In this embodiment, the two sliding channels 1113 are separated to prevent one headband 120 from squeezing the other headband 120 when adjusting one headband 120.

[0044] Furthermore, the headband positioning assembly 110 also includes two elastic positioning elements 112, which are respectively disposed in two sliding channels 1113.

[0045] Each headband 120 has multiple positioning parts 121 at its upper end, and the multiple positioning parts 121 are arranged at intervals in the left and right direction. The upper ends of the two headbands 120 are respectively movably inserted into the two sliding channels 1113, and the two headbands 120 correspond to the elastic positioning members 112 in their respective sliding channels 1113. The headbands 120 can be operably moved in the left and right direction, and different positioning parts 121 are positioned and engaged with the elastic positioning members 112. The lower end of the headband 120 is used to connect to the sound generating unit 200.

[0046] It is understood that the upper ends of the left and right headbands 120 are respectively inserted into the left and right sliding channels 1113 of the guide member 111; wherein, the left headband 120 is positioned and engaged with the elastic positioning member 112 in the left sliding channel 1113, that is, the elastic positioning member 112 in the left sliding channel 1113 can position the left headband 120; the right headband 120 is positioned and engaged with the elastic positioning member 112 in the right sliding channel 1113, that is, the elastic positioning member 112 in the right sliding channel 1113 can position the right headband 120.

[0047] By moving each headband 120 left and right, its lateral position can be adjusted, thereby adjusting the distance between the left and right sound units 200. This changes the clamping force when the headphones are worn on the user's head, allowing the headphones to adapt to users with different head shapes. Specifically, once the lateral position of the headband 120 is adjusted and a positioning part 121 of the headband 120 is engaged with the elastic positioning member 112, the headband 120 can be positioned, reducing the risk of the headband 120 sliding freely relative to the headband positioning component 110 and changing its position.

[0048] It should be noted that the left and right distance between the two headbands 120 can be adjusted by adjusting the position of only one headband 120 relative to the headband positioning component 110, or by adjusting the position of both headbands 120 relative to the headband positioning component 110.

[0049] The headband unit 100 of this utility model splits a traditional complete headband into two headbands 120 and uses a headband positioning component 110 to adjust the left and right distance between the two headbands 120, thereby changing their clamping force. The structure is simple.

[0050] Understandably, the headband 120 can be made of steel or other flexible materials to provide a clamping effect and reduce the risk of the headphones falling off the user's head. Additionally, the steel construction of the headband 120 facilitates pulling and changing its position relative to the headband positioning component 110.

[0051] Combination Figure 4 and Figure 5 In some embodiments, the sliding channel 1113 includes a groove area 11131 and a mounting area 11132. The groove area 11131 extends through the end of the guide member 111, and the mounting area 11132 is arranged perpendicular to the left-right direction to the groove area 11131. The upper end of the headband 120 is movably inserted through the groove area 11131, and the elastic positioning member 112 is disposed in the mounting area 11132 and faces the groove area 11131.

[0052] Specifically, the groove area 11131 of the left sliding channel 1113 passes through the left end of the guide member 111, and the groove area 11131 of the right sliding channel 1113 passes through the right end of the guide member 111; for each sliding channel 1113, its mounting area 11132 and the groove area 11131 are arranged vertically.

[0053] One of the elastic positioning elements 112 is disposed in the mounting area 11132 of the left sliding channel 1113 and is positioned toward the slide groove area 11131 of the left sliding channel 1113. The other elastic positioning element 112 is disposed in the mounting area 11132 of the right sliding channel 1113 and is positioned toward the slide groove area 11131 of the right sliding channel 1113. The mounting area 11132 can provide mounting space for the elastic positioning elements 112.

[0054] Furthermore, the upper end of the left headband 120 is movably inserted into the groove area 11131 of the left sliding channel 1113, and the upper end of the right headband 120 is movably inserted into the groove area 11131 of the right sliding channel 1113. The groove area 11131 can provide an insertion space for the upper end of the headband 120 and can provide a guiding function for the sliding of the upper end of the headband 120.

[0055] The installation area 11132 includes two limiting sidewalls 11132a spaced apart in the left and right directions. For the elastic positioning member 112 corresponding to the installation area 11132, the elastic positioning member 112 is limited between the two limiting sidewalls 11132a.

[0056] Understandably, the two limiting sidewalls 11132a can prevent the elastic positioning element 112 from dislodging from the mounting area 11132 in the left and right directions.

[0057] Furthermore, the installation area 11132 also includes a connecting wall 11132b connected between the two limiting sidewalls 11132a; in each sliding channel 1113, the connecting wall 11132b is spaced apart from and opposite to the sliding groove area 11131; for the elastic positioning member 112 corresponding to the installation area 11132, the elastic positioning member 112 is fixed to the connecting wall 11132b.

[0058] It is understandable that the elastic positioning element 112 can be fixed to the connecting wall 11132b by adhesive or snap-fit, or by fasteners such as screws. By fixing the elastic positioning element 112 to the connecting wall 11132b, it is possible to prevent the headband 120 from pulling the elastic positioning element 112 to move left and right along with the headband 120 during the pushing and pulling process.

[0059] It should be noted that the guide component 111 includes a lower shell 1111 and an upper shell 1112. The lower shell 1111 and the upper shell 1112 are assembled together to form a sliding channel 1113. The upper shell 1112 is provided with an installation area 11132. The elastic positioning component 112 can be installed in the installation area 11132 of the upper shell 1112 first, and then the upper shell 1112 and the lower shell 1111 are assembled together.

[0060] Combination Figure 8 and Figure 9 In some embodiments, the inner wall of the sliding channel 1113 is provided with an anti-slip portion 1114, and the upper end of the headband 120 is provided with a limiting portion 122. The anti-slip portion 1114 is located on the path of the limiting portion 122 moving in the extraction direction.

[0061] It is understandable that when the headband 120 is pulled, the lateral distance between the two headbands 120 will increase. When the headband 120 is pulled, the limiting part 122 will move together. By forming an anti-slip part 1114 on the inner wall of the sliding channel 1113 and making the anti-slip part 1114 located on the path of the limiting part 122 moving in the pulling direction, the upper end of the entire headband 120 can be prevented from being pulled out of the sliding channel 1113, thereby preventing the headband 120 from detaching from the headband positioning assembly 110.

[0062] Among them, the anti-slip part 1114 is a step or protrusion formed on the inner wall of the groove area 11131, and the limiting part 122 is a protrusion provided at the upper end of the headband 120.

[0063] Specifically, the slide area 11131 has a wider first region 111311 and a narrower second region 111312. The second region 111312 extends through the end of the guide member 111. The first region 111311 is closer to the center of the guide member 111 than the second region 111312. The anti-slip part 1114 is a step formed between the first region 111311 and the second region 111312. Limiting parts 122 are provided on the front and rear sides of the upper end of the headband 120. The limiting parts 122 are located within the first region 111311, and the limiting parts 122 and the anti-slip part 1114 are arranged opposite each other in the left and right direction. The anti-slip part 1114 can prevent the entire upper end of the headband 120 from being pulled out of the sliding channel 1113.

[0064] In other embodiments, the anti-detachment part 1114 may be a separate component disposed within the sliding channel 1113.

[0065] Combination Figure 5 , Figure 6 and Figure 7In some embodiments, the positioning part 121 is a positioning hole; the elastic positioning member 112 includes an elastic part 1121 and a positioning protrusion 1122 connected to the elastic part 1121; the headband 120 is operable to move in the left and right direction and to allow the positioning protrusion 1122 to pass through different positioning holes.

[0066] Understandably, the elastic part 1121 is an elastic sheet with a curved shape. The elastic part 1121 is connected to the connecting wall 11132b and the positioning protrusion 1122 is positioned facing the upper end of the headband 120. The positioning protrusion 1122 is used to abut against the upper end of the headband 120. When it is necessary to adjust the left and right distance between the two headbands 120, the headband 120 can be moved in the left and right direction. During the left and right movement of the headband 120, the positioning protrusion 1122 can be inserted into different positioning holes in turn. When the position of the headband 120 is adjusted and the positioning protrusion 1122 is inserted into a certain positioning hole, the elastic part 1121 can press the positioning protrusion 1122 against the headband 120 under the elastic action, reducing the risk of the headband 120 moving left and right at will.

[0067] It should be noted that the positioning hole can be a through hole or a blind hole.

[0068] Furthermore, the side of the positioning protrusion 1122 closest to the headband 120 has an arc-shaped structure. Thus, when adjusting the left and right position of the headband 120, the positioning protrusion 1122 and the headband 120 will slide relative to each other. Making the outer surface of the positioning protrusion 1122 arc-shaped makes the relative sliding between the headband 120 and the positioning protrusion 1122 smoother, especially when the positioning protrusion 1122 slides out of a positioning hole, reducing the problem of jerking.

[0069] In some other embodiments, the positioning part 121 is a positioning groove.

[0070] In the headphones of this invention, two headbands 120 are connected to the left and right sides of a headband positioning assembly 110, one on the left and one on the right. The headband positioning assembly 110 connects the two headbands 120 together, and the left and right headbands 120 are respectively connected to the left and right sound units 200. The upper ends of the left and right headbands 120 are respectively inserted into the left and right sliding channels 1113 of the guide member 111. The left headband 120 is positioned and engaged with the elastic positioning member 112 in the left sliding channel 1113, that is, the elastic positioning member 112 in the left sliding channel 1113 can position the left headband 120; the right headband 120 is positioned and engaged with the elastic positioning member 112 in the right sliding channel 1113, that is, the elastic positioning member 112 in the right sliding channel 1113 can position the right headband 120. By moving each headband 120 left and right, the lateral position of each headband 120 can be adjusted, thereby adjusting the distance between the left and right sound units 200. This changes the clamping force after the headphones are worn on the user's head, allowing the headphones to adapt to users with different head shapes. Specifically, once the lateral position of the headband 120 is adjusted and a positioning part 121 of the headband 120 is engaged with the elastic positioning member 112, the position of the headband 120 can be fixed, reducing the risk of the headband 120 sliding freely relative to the headband positioning component 110 and changing its position. The headband unit 100 of this invention simply splits a traditional single headband into two headbands 120 and uses the headband positioning component 110 to adjust the lateral distance between the two headbands 120, thereby changing their clamping force. The structure is simple.

[0072] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
