[0053] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0054] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplifying the present application, the components and arrangements of the specific examples are described in the following. Of course, they are merely examples and are not intended to limit the present application. Furthermore, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements being discussed.

[0055] For the purpose of description, spatial relative terms can be used in the description to describe the relative position relationship or movement of one element or feature with respect to another element or feature as shown in the drawings, such as "internal", "external", "inboard", "outboard", "under", "below", "on", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings.

Therefore, the example term "below" can include both upward and downward orientations. The device can be additionally oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used in the text are interpreted accordingly.

[0056] The present application provides a headband, which can adjust the clamping force. The headband can be applied to earphones, especially a headset, which includes a headband and earphone units, and the two ends of the headband are respectively connected with the earphone units. The headband is worn on the head position of the user, and the earphone units can cover the ears of the user. By adjusting the clamping force of the headband, the clamping force of the two earphone units can be adjusted, the use comfort of the earphones can be improved, and the earphone product can be adapted to more users.

[0057] Figures 1 to 4The headband provided by the embodiment of the present application comprises a head cover 1, a movable band 2 and an adjusting device 3. The head cover 1 is arc-shaped and is provided with a first adjusting hole 1a. The movable band 2 is located at the inner side of the head cover 1 and is fixedly connected to the middle part of the head cover 1. The adjusting device 3 comprises a sliding member 31 and an adjusting member 32 connected to the sliding member 31. The sliding member 31 is movably arranged between the movable band 2 and the head cover 1. In the embodiment, the two opposite sides of the sliding member 31 are slidably attached to the movable band 2 and the head cover 1 respectively. In other embodiments, the two opposite sides of the sliding member 31 are rollingly connected to the movable band 2 and the head cover 1 respectively.

[0058] It should be noted that the middle part of the head cover 1 can be the position of the highest point of the head cover 1, can be the position close to the highest point of the head cover 1, or can be other positions between the highest point of the head cover 1 and the first adjusting hole 1a. The head cover 1 provides a fixed position for the non-end part of the movable band 2. Preferably, the movable band 2 is fixedly connected to the inner side of the highest point of the head cover 1.

[0059] Referring to Figure 2 , Figure 6 and Figure 7 , the movable band 2 is fixedly connected to the middle part of the head cover 1, and the sliding member 31 is located between the movable band 2 and the head cover 1, so that a gap 10a is formed between the movable band 2 and the head cover 1. The sliding member 31 is movably arranged. During the movement of the sliding member 31, the movable band 2 can be pushed to be close to or away from the head cover 1. Since the movable band 2 is fixedly connected to the middle part of the head cover 1, the distance between the end part of the movable band 2 and the head cover 1 is adjusted when the sliding member 31 moves, that is, the clamping force of the headband is adjusted.

[0060] In an embodiment, when the earphone unit is connected to the head cover 1, the clamping force of the headband is adjusted by moving the movable band 2 through the sliding member 31, and the position of the head cover 1 is not changed, so the position of the earphone unit is not changed. That is, the clamping force of the headband can be adjusted without adjusting the position of the earphone unit.

[0061] Since the sliding member 31 is hidden between the movable band 2 and the head cover 1, it is not convenient to directly adjust the position of the sliding member 31. In order to facilitate the adjustment operation, the adjusting member 32 is arranged in the embodiment.

[0062] The adjusting member 32 is connected to the sliding member 31 and is arranged in the first adjusting hole 1a. Part of the adjusting member 32 extends out of the first adjusting hole 1a. Referring to Figure 3The end of the adjusting member 32 away from the sliding member 31 passes through the first adjusting hole 1a to the outside of the head cover 1. In this way, the first adjusting hole 1a plays a guiding and limiting role for the movement of the adjusting member 32. When the user needs to adjust the clamping force of the headband, the end of the adjusting member 32 away from the sliding member 31 is only needed to be operated, so that the adjusting member 31 moves along the first adjusting hole 1a. When the adjusting member 32 moves along the first adjusting hole 1a, the sliding member 31 is driven to move, thereby adjusting the distance between the end of the movable band 2 and the head cover 1. At the same time, the length of the first adjusting hole 1a itself limits the movement range of the adjusting member 32.

[0063] As shown in Figure 4 , in the technical scheme of the embodiment, at least one end of the head cover 1 is provided with a first adjusting hole 1a. The first adjusting hole 1a is a strip-shaped hole, and the first adjusting hole 1a extends along the length direction of the head cover 1.

[0064] When the user adjusts the position of the sliding member 31 through the adjusting member 32, the sliding member 31 can be stopped at any position in the adjustable range, so that stepless adjustment can be realized, and the needs of the user for different tightness can be met.

[0065] Referring to Figure 1 , the headband has an arc-shaped wearing space 10b to fit the head of the user, and can provide clamping force to the earphone unit connected to the two ends of the headband, so that the headphones are stably worn on the head of the user. When the clamping force needs to be adjusted, the distance between the end of the movable band 2 and the head cover 1 can be adjusted through the adjusting device 3.

[0066] The movable band 2 is fixed to the middle part of the head cover 1. On the one hand, the position of the movable band 2 can be fixed, so that the movable band 2 is prevented from moving left and right. On the other hand, since the movable band 2 is always fixed to the head cover 1, and the sliding member 31 is clamped between the movable band 2 and the head cover 1, the distance between the movable band 2 and the head cover 1 becomes larger and larger from the middle part of the movable band 2 to the end of the movable band 2.

[0067] Referring to Figure 6 and Figure 7 , the sliding member 31 is located at two different positions. Figure 6 In the first position, Figure 7 In the second position, the sliding member 31 is farther away from the highest point of the head cover 1 than in the first position. When the sliding member 31 is located at the second position, the distance between the end of the movable band 2 and the head cover is greater than when the sliding member 31 is located at the first position. Correspondingly, when the sliding member 31 is located at the second position, the distance L2 between the two ends of the movable band 2 is smaller than the distance L1 between the two ends of the movable band 2 when the sliding member 31 is located at the first position.

[0068] The distance between the two ends of the movable band 2 itself is reduced. When the earphones are worn on the user's head, the smaller the distance between the two ends of the movable band 2 is, the greater the clamping force generated on the user.

[0069] The distance between the two ends of the movable band 2 itself increases. When the earphone is worn on the user's head, the distance between the two ends of the movable band 2 increases, and the clamping force exerted on the user is reduced.

[0070] In this embodiment, the movable belt 2 is a steel belt. It can be understood that the strength and wear resistance of the steel belt can provide a stable clamping force while increasing the service life of the movable belt.

[0071] In some embodiments, the number of the adjusting device 3 is one, and a gap 10 a is formed between one end of the movable belt 2 and the head cover 1 .

[0072] In this embodiment, there are two adjustment devices 3, and a gap 10a is formed between the two ends of the movable band 2 and the head cover 1. The clamping force can be adjusted by moving one adjustment device 3, or by moving both adjustment devices 3. Adjusting the clamping force by moving both adjustment devices 3 provides a more stable clamping force for the headband, improving the stability of the headset when worn by the user and further enhancing the user experience.

[0073] like Figure 1 and Figure 2 As shown, a connecting post 11 is provided on the side of the head cover 1 facing the movable belt 2, and the movable belt 2 is provided with a connecting hole. The connecting post 11 is passed through the connecting hole, and the head cover 1 and the movable belt 2 are fixedly connected by connecting a fastener to the connecting post 11. Exemplarily, the fastener is a screw, and the fastener is threadedly connected to the connecting post 11.

[0074] In some other embodiments, the movable belt 2 can also be fixedly connected to the middle position of the head cover 1 by means of glue dispensing or hot melting. It should be noted that the method for achieving the fixed connection between the movable belt 2 and the head cover 1 is not limited to the method mentioned in the embodiment of the present application, and other methods can also be used to achieve the fixed connection, which will not be repeated here.

[0075] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in the technical solution of this embodiment, the adjustment device also includes an adjustment button 33, which is connected to the adjustment member 32 and is located on the outside of the head cover 1. In this way, the adjustment button 33 is provided to provide the user with an operating position, so that the user can adjust the clamping force by himself.

[0076] In this embodiment, the width of the first adjustment hole 1 a is smaller than the width of the adjustment button 33 . When the adjustment button 33 is circular, the width of the adjustment button 33 refers to the diameter of the adjustment button 33 .

[0077] As Figure 5 shown in the embodiment, the sliding member 31 comprises a body and a protrusion 311 protruding from the body, and the side of the body facing the activity band 2 is provided with the protrusion 311 abutting against the activity band 2. It can be understood that the contact area between the sliding member 31 and the activity band 2 can be reduced by the contact between the protrusion 311 and the activity band 2, and the frictional force acting on the sliding member 31 during movement can be reduced.

[0078] Exemplarily, as Figure 5 shown, the side of the sliding member 31 facing the activity band 2 is also provided with an inclined surface 312, so that the cross-sectional dimension of the sliding member 31 in the direction towards the middle part of the headband gradually decreases. In this way, the setting of the inclined surface 312 and the gap between the inclined surface 312 and the activity band 2 can reduce the contact area between the sliding member 31 and the activity band 2, and reduce the frictional force acting on the sliding member 31 during movement. On the other hand, the cross-sectional dimension of the sliding member 31 in the direction towards the middle part of the headband is designed to gradually decrease, which can avoid the situation that the sliding member 31 is stuck during movement, and ensure smooth movement of the sliding member 31.

[0079] In the embodiment, the side of the sliding member 31 facing the activity band 2 is provided with two inclined surfaces 312, so that the cross-sectional dimension of the sliding member 31 in the direction from the protrusion 311 in the middle part to the middle part of the headband gradually decreases, and the cross-sectional dimension of the sliding member 31 in the direction from the protrusion 311 in the middle part to the end part of the headband gradually decreases.

[0080] In another embodiment, the side of the body facing the activity band 2 is planar, and the connection between the protrusion 311 and the body is stepped.

[0081] As Figure 1 , Figure 2 and Figure 4 shown, in the technical solution of the embodiment, the activity band 2 comprises an arc-shaped part 22 and a bent part 21, the arc-shaped part 22 is located on the inner side of the head cover 1, and the arc-shaped part 22 is arc-shaped to adapt to the head cover. The arc-shaped part 22 is fixedly connected with the middle part of the head cover 1; the bent part 21 is connected to the end part of the arc-shaped part 22 and is inclined towards the direction away from the head cover 1; wherein when the adjusting member 32 moves along the first adjusting hole 1a, the sliding member 31 is driven to move, thereby adjusting the distance between the bent part 21 and the head cover 1.

[0082] It can be understood that, due to the bending part 21 bending and tilting towards the direction away from the head cover 1, the gap 10a between the bending part 21 and the head cover 1 can be larger than the end of the movable band 2 without bending. When the sliding block moves to the bending part, the gap 10a changes greatly when the sliding member 31 moves from the middle to the end direction; similarly, the gap 10a changes greatly when the sliding member 31 moves from the end to the middle direction; the larger gap 10a change can obtain a larger clamping force adjustment range, and the user can more obviously perceive the adjustment of the clamping force during the adjustment.

[0083] In order to facilitate production and molding, in the technical scheme of the embodiment, the bending part 21 and the arc-shaped part 22 are integrally formed.

[0084] In order to ensure the comfort of the clamping effect, the bending part 21 and the arc-shaped part 22 are connected at an included angle, and the included angle is obtuse.

[0085] In order to ensure that the sliding member can smoothly transition when passing through the connection between the bending part 21 and the arc-shaped part 22, in the embodiment, the connection between the bending part 21 and the arc-shaped part 22 is designed to be arc-shaped transition.

[0086] In the embodiment, the bending part 21 is flat. In another embodiment, the bending part can also be designed to be arc-shaped.

[0087] As shown in Figure 1 , Figure 2 and Figure 4 , in the technical scheme of the embodiment, the number of bending parts 21 is two, and each is connected to one end of the arc-shaped part 22; the two bending parts 21 are oppositely arranged. In this way, the structure is symmetrical, and the clamping is more stable.

[0088] In the embodiment, in order to simplify the structure, facilitate assembly and disassembly, as shown in Figure 3 , in the technical scheme of the embodiment, the sliding member 31 is provided with an assembly hole 31a; the adjusting member 32 is arranged in the assembly hole 31a.

[0089] As shown in Figure 4 , in the technical scheme of the embodiment, the movable band 2 is provided with a second adjusting hole 2a; the second adjusting hole 2a is arranged corresponding to the first adjusting hole 1a; the adjusting member 32 is arranged in the second adjusting hole 2a, and the adjusting member 32 can move along the second adjusting hole 2a.

[0090] It can be understood that, by arranging the second adjusting hole 2a and the adjusting member 32 arranged in the second adjusting hole 2a, the movement position of the sliding member 31 can be further limited. At the same time, the sliding member 31 is assembled in the head cover 1 and the movable band 2 through the parts at both ends of the adjusting member 32, improving the stability of the sliding member 31 when moving.

[0091] like Figure 4 As shown, in the technical solution of this embodiment, the second adjustment hole 2a extends from the arc portion 22 to the bent portion 21. Specifically, the second adjustment hole 2a includes a first half hole (not numbered in the figure) and a second half hole (not numbered in the figure). The first half hole is located in the arc portion 22, and the second half hole is located in the bent portion 21.

[0092] When the adjusting member 32 moves along the first adjusting hole 1 a , the adjusting member 32 will simultaneously move along the first half hole or the second half hole, and drive the sliding member 31 to move, thereby adjusting the distance between the bending portion 21 and the head cover 1 .

[0093] It can be understood that by extending the opening range of the second adjustment hole 2a from the arc portion 22 to the bent portion 21, while the second adjustment hole 2a and the first adjustment hole 1a jointly guide and limit the movement of the sliding member 31, the sliding member 31 can also pass through the connection between the arc portion 22 and the bent portion 21 during the movement, ensuring that the user can more clearly perceive the adjustment of the clamping force during the adjustment process.

[0094] like Figure 3 As shown, in the technical solution of this embodiment, the adjustment device 3 also includes a fastening screw 35; the screw rod of the fastening screw 35 is threadedly connected to the adjustment member 32, and the nut of the fastening screw 35 abuts against the side of the movable belt 2 away from the head cover 1.

[0095] It is understandable that by providing the fastening screw 35 , the adjusting member 32 can be stably assembled and prevented from falling off.

[0096] like Figure 3 As shown, in the technical solution of this embodiment, the adjustment device 3 also includes a sliding washer 36, which is mounted on the fastening screw 35 and located between the movable band 2 and the nut of the fastening screw 35. The adjustment member 32 extends out of the second adjustment hole 2a and abuts against the sliding washer 36. The provision of the sliding washer 36 prevents direct contact and friction between the fastening screw 35 and the movable band 2, improving safety. Furthermore, the provision of the sliding washer 36 ensures smoother movement of the adjustment device 3.

[0097] like Figure 4 As shown, in this embodiment, a positioning groove 36 a is provided on the side of the sliding gasket 36 facing the movable belt 2 , and an end of the adjusting member 32 facing away from the adjusting button 33 is inserted into the positioning groove 36 a .

[0098] In another aspect, the application also provides an earphone, comprising two earphone units and the headband as above, the specific structure of which is referred to the above-mentioned embodiments, since the earphone adopts all the technical solutions of the above-mentioned embodiments, thus at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. Wherein, the two earphone units are respectively connected to the two ends of the headband.
