Technical Field

[0001] This invention relates to the field of headphone technology, and more specifically to a wearable device. Background Technology

[0002] On-ear headphones present a contradictory problem in terms of wearing comfort, wearing stability, and passive noise cancellation. Improving wearing comfort requires sacrificing passive noise cancellation, and vice versa. It is difficult to achieve both simultaneously. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a wearable device.

[0004] The specific technical solution adopted is as follows: A wearable device, comprising: A headband is worn on the user's head. Wearing unit designed to fit snugly against the user's ear; A first connecting structure is used to connect the headband and the wearing unit, and enables the wearing unit to rotate relative to the headband; The second connection structure is used to apply a first force to the wearing unit when the wearing unit rotates relative to the headband in a first direction to separate the wearing unit from the ear, the direction of the first force being opposite to the first direction.

[0005] In some embodiments, the first connection structure is disposed on the wearing unit, and the second connection structure is disposed on the first connection structure.

[0006] In some embodiments, the first connecting structure includes a first rotating part and a second rotating part; The first rotating part is used to rotate the wearing unit around a first axis to match a first angle of the user's ear; The second rotating part is used to rotate the wearing unit around the second axis to match the second angle of the user's ear.

[0007] In some embodiments, the first rotating part includes a first rotating shaft and a first bracket; the second rotating part includes a second rotating shaft and a second bracket; The first rotating shaft is connected to the head beam, and the first bracket is rotatably connected to the first rotating shaft; the axis of the first rotating shaft forms the first axis. The second rotating shaft is disposed on the first bracket, the second bracket is connected to the wearing unit, the second bracket is rotatably connected to the second rotating shaft, and the axis of the second rotating shaft forms the second axis. The second bracket rotates relative to the first bracket in a first direction to separate the wearing unit from the ear; the second bracket rotates relative to the first bracket in a second direction to fit the wearing unit into the ear.

[0008] In some embodiments, the second connection structure connects the first bracket and the second bracket; The second connection structure includes an elastic element. When the second bracket rotates in the first direction, the elastic element in the second connection structure undergoes elastic deformation and generates the first force.

[0009] In some embodiments, the wearing unit includes an ear pad; the ear pad is used to fit against the auricle of the ear, and the thickness of the portion of the ear pad that fits against the lower part of the auricle is greater than the thickness of the portion of the ear pad that fits against the upper part of the auricle, so that the ear pad fits against the auricle.

[0010] In some embodiments, the wearing unit further includes an ear shell, the ear pad is disposed on the ear shell, and the first connecting structure is disposed inside the ear shell and connects the ear shell and the headband.

[0011] In some embodiments, the first connecting structure is slidably connected to the headband, the first connecting structure is fixedly connected to the wearing unit, and the first connecting structure can drive the wearing unit to slide along the extension direction of the headband.

[0012] In some embodiments, the headband further includes a deformable portion and a fixing portion located at the end of the deformable portion, the first connecting structure being connected to the fixing portion, and the deformable portion being able to expand or contract in accordance with changes in the user's head circumference. The deformable part has a deformation gap, which can adapt to changes when the deformable part expands or contracts, so that the pressure of the headband on the user's head is evenly distributed.

[0013] In some embodiments, the headband further includes a flexible pad disposed on the deformable portion and used to fit the user's head. Attached Figure Description

[0017] To further illustrate the technical means and effects adopted by the present invention to achieve its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of an XXX proposed according to the present invention. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0019] The specific solution of a wearable device provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0020] This application provides a wearable device, which can encompass various types of devices, including but not limited to headphones, smart head-mounted devices, and hearing aids. This application uses headphones as an example for illustration only.

[0021] like Figures 1 to 3 As shown, the wearable device in this embodiment includes a headband 1, a wearing unit 2, a first connecting structure 3, and a second connecting structure 4.

[0022] The headband 1 is worn on the user's head. The headband 1 can be made of elastic metal or plastic with a certain curvature. Its curvature design conforms to the physiological curve of the human head. It can be directly fastened to the user's head and naturally fits the upper part of the head when worn, distributing the wearing pressure.

[0023] Wearing unit 2 is designed to fit snugly against the user's ear. Wearing unit 2 can integrate a sound-generating module and noise-canceling components to provide clear and full sound quality.

[0024] The first connecting structure 3 is used to connect the headband 1 and the wearing unit 2, and enables the wearing unit 2 to rotate relative to the headband 1, thereby allowing the wearing unit 2 to better adapt to the angle and position of different users' ears, improving the fit and comfort of wearing.

[0025] For example, different users may have different ear positions on their heads and different auricle tilt angles. The rotation characteristics of the first connecting structure 3 can adapt to these individual differences, ensuring good contact between the wearing unit 2 and the ear, thus laying the foundation for subsequent stable wearing and functional realization.

[0026] The second connecting structure 4 applies a first force to the wearing unit 2 when it rotates relative to the headband 1 in a first direction, causing the wearing unit 2 to separate from the ear. The direction of the first force is opposite to the first direction. The first force generated by the second connecting structure 4 automatically pulls the wearing unit 2 back in a second direction (i.e., closer to the ear), thereby reducing the possibility of the wearing unit 2 separating from the ear and ensuring the stability of the wearable device during use. This automatic reset feature is particularly suitable for sports scenarios or daily activities, avoiding the hassle of frequent manual adjustments and improving ease of use.

[0027] The wearable device in this embodiment, through the synergistic effect of the first connecting structure 3 and the second connecting structure 4, effectively balances wearing comfort and passive noise cancellation. When the user wears the device, the first connecting structure 3 allows the wearing unit 2 to rotate flexibly according to the angle of the user's ear, ensuring that the ear pad 21 fits naturally and closely to the auricle. The second connecting structure 4 provides a continuous counterforce when the wearing unit 2 tends to slip out of the ear (such as when the user shakes their head or is subjected to slight external force), keeping the wearing unit 2 in contact with the ear and thus ensuring the seal required for passive noise cancellation. See Figure 10 As shown, with other components remaining unchanged, the passive noise reduction at high frequency (1.5kHz~10kHz) positions in the contoured ear cap (i.e., the wearable device of this application) is improved by 10dB compared to an ear cap of equal thickness.

[0028] like Figures 3 to 5 As shown, in some embodiments, the first connecting structure 3 and the second connecting structure 4 can be two independent structures that play different roles.

[0029] The first connecting structure 3 can be disposed on the wearing unit 2 and fixedly connected to the wearing unit 2. By controlling the first connecting structure 3 separately, the wearing unit 2 can be rotated relative to the headband 1.

[0030] For example, the first connecting structure 3 can be designed to form an integral structure with the ear shell 22 of the wearing unit 2, or a stable connection can be achieved by means of bolts, buckles, etc., to ensure that there is no relative displacement between the wearing unit 2 and the first connecting structure 3 during rotation.

[0031] The second connecting structure 4 can be integrated onto the first connecting structure 3. For example, when the first connecting structure 3 includes two relatively rotatable components, the second connecting structure 4 can be connected between these two components, so that when the first connecting structure 3 drives the wearing unit 2 to rotate, the second connecting structure 4 can respond promptly and apply a corresponding force. This arrangement makes the structural layout more compact, reduces the overall space occupied, and also facilitates assembly and maintenance.

[0032] For example, in some embodiments, the first connecting structure 3 may include a first rotating part 36 and a second rotating part 37, which rotate around different axes to form a multi-dimensional adjustment space.

[0033] The first rotating part 36 is used to rotate the wearing unit 2 around the first axis to match the first angle of the user's ear; the second rotating part 37 is used to rotate the wearing unit 2 around the second axis to match the second angle of the user's ear.

[0034] The first angle can be the forward / backward tilt angle of the user's ear, and the second angle can be the vertical tilt angle of the user's ear. Alternatively, the first angle can be the vertical tilt angle of the user's ear, and the second angle can be the forward / backward tilt angle of the user's ear. This application embodiment only uses the example where the first angle can be the forward / backward tilt angle of the user's ear, and the second angle can be the vertical tilt angle of the user's ear for illustration.

[0035] The first axis can be set to extend approximately along the headband 1. By rotating around this axis, the wearing unit 2 can adjust its tilt angle in the front-to-back direction to match the first angle of the user's ear. For example, refer to... Figure 10 As shown, when the user's ear is bent forward or backward, the wearing unit 2 can maintain a good fit with the auricle through the adjustment of the first rotating part 36.

[0036] The second axis can be designed to be perpendicular to or at a certain angle to the first axis, for example, extending approximately vertically. Rotation around this axis can adjust the vertical deflection angle of the wearing unit 2 to match the second angle of the user's ear. (Refer to...) Figure 11 As shown, when different users have different degrees of up-and-down tilt of their auricles, the second rotating part 37 can be adjusted accordingly to ensure that the ear pad 21 of the wearing unit 2 can fully fit the contour of the auricle.

[0037] Through the coordinated action of the first rotating part 36 and the second rotating part 37, the wearing unit 2 can achieve an effect similar to universal adjustment. When there are individual differences in the user's head size, or when the head posture changes during long-term wear, the first rotating part 36 and the second rotating part 37 can finely adjust the front-to-back tilt angle and the up-to-down tilt angle of the wearing unit 2, so as to always keep the ear pad 21 in close contact with the auricle, effectively reducing the pressure or sound leakage caused by improper wearing angle.

[0038] The structure of the first rotating part 36 and the structure of the second rotating part 37 can take many forms. For example, a ball joint structure can be used to achieve multi-angle rotation through the cooperation of the ball head and the ball socket. The rotation angle range is large and the adjustment is flexible, which can better adapt to the subtle differences in the ear angle of different users.

[0039] A hinge structure can also be used, which achieves rotation of a specific axis through the cooperation of a pin and a bushing. The structure is simple and reliable, with low cost and good rotational stability.

[0040] Alternatively, a gear meshing structure can be used, where rotation adjustment is achieved through meshing gear sets. This facilitates precise control of the rotation angle and provides a good positioning effect after adjustment, preventing angle shift due to accidental contact during wear.

[0041] For example, such as Figures 4 to 7 As shown, in some embodiments, the first rotating part 36 may include a first rotating shaft 32 and a first support 31. The first rotating shaft 32 may be disposed at the end of the head beam 1 and fixedly connected to the head beam 1 or integrally formed therefrom.

[0042] The first rotating shaft 32 can be arranged in a direction that is approximately parallel to the extension direction of the headband 1 or perpendicular to the sagittal plane of the user's head, and the axis of the first rotating shaft 32 can form a first axis. The first bracket 31 is rotatably connected to the first rotating shaft 32, that is, the first bracket 31 is provided with a shaft hole or bushing that matches the first rotating shaft 32, and the first rotating shaft 32 passes through the shaft hole or bushing, so that the first bracket 31 can rotate freely around the axis of the first rotating shaft 32 (i.e., the first axis), thereby allowing the first bracket 31 to swing inward (towards the head) or outward (away from the head) around the axis.

[0043] With the first rotating part 36, the wearing unit 2 can adapt to the differences in head width and the tilt angle of the auricle relative to the side of the head of different users. When the user's head is wider or the auricle is more outwardly flared, the first bracket 31 swings outward at a certain angle; when the head is narrower or the auricle is closer together, the first bracket 31 swings inward, so that the subsequent wearing unit 2 can form a preliminary alignment with the auricle. Here, swinging outward can be understood as moving away from the user's cheek, and swinging inward can be understood as moving closer to the user's cheek.

[0044] The second rotating part 37 may include a second rotating shaft 34 and a second support 33. The second rotating shaft 34 may be disposed on the first support 31, and the axis of the second rotating shaft 34 forms a second axis.

[0045] For example, the first bracket 31 may be provided with a bearing seat or a shaft hole, and the second rotating shaft 34 is fixed in the bearing seat. Its axis (i.e. the second axis) is approximately perpendicular to the first axis and extends approximately perpendicular to the extension direction of the headband 1 or along the vertical direction of the user's head when worn.

[0046] The second bracket 33 is rotatably connected to the second rotating shaft 34, that is, the second bracket 33 is provided with a shaft hole or bushing that matches the second rotating shaft 34, and the second rotating shaft 34 passes through it, so that the second bracket 33 can rotate freely around the second axis.

[0047] The second bracket 33 is fixedly connected to the wearing unit 2, which can be achieved through threaded connection, snap-fit, or integral molding. For example, such as... Figure 4 and Figure 5 As shown, the second bracket 33 can be fixed to the wearing unit 2 by bolts 35.

[0048] With the second rotating part 37, the wearing unit 2 can swing up and down around the second axis to adapt to the vertical tilt angle of the auricle relative to the head of different users. When the upper part of the auricle is closer to the lower part and the lower part is wider, the second bracket 33 rotates around the second axis, so that the lower part of the wearing unit 2 is closer to the lower part of the auricle, achieving a precise match with the physiological angle of the auricle.

[0049] As for the structure of the first bracket 31 and the structure of the second bracket 33 in this embodiment, they can be designed according to actual assembly requirements and rotation angle range.

[0050] For example, the first bracket 31 can be designed as an "L"-shaped structure, with one end engaging with the first rotating shaft 32 through a shaft hole, and the other end extending to a bearing for mounting the second rotating shaft 34. This structure ensures the stability of the first bracket 31 rotating around the first axis and provides a stable mounting base for the second rotating part 37. The second bracket 33 can be designed as a plate-like structure with a certain curvature, with one end rotatably connected to the second rotating shaft 34 and the other end tightly fixed to the ear shell 22 of the wearing unit 2 by bolts. The curvature design can adapt to the shape of the wearing unit 2, making the overall structure more compact.

[0051] In some embodiments, a limiting structure may be provided between the first support 31 and the first rotating shaft 32 to limit the swing angle range of the first support 31. For example, the swing range of the first support 31 may be limited to 0°–15° inward and 0°–20° outward to prevent excessive swinging from causing structural damage or unstable wearing. Simultaneously, a limiting structure may also be provided between the second support 33 and the first support 31 to limit the rotation range of the second support 33 around the second axis. For example, the rotation range in the second direction (fitting direction) may be limited to 0°–25°, and the rotation range in the first direction (separation direction) may be limited to 0°–30° to accommodate differences in auricular angle among individuals, while avoiding excessive rotation that could cause auricular compression.

[0052] like Figure 4 and Figure 5 As shown, in some embodiments, the second connecting structure 4 of this embodiment connects the first support 31 and the second support 33. The second connecting structure 4 is constructed as an elastic element, with one end connected to the first support 31 and the other end connected to the second support 33. When the second support 33 rotates in a first direction, the elastic element in the second connecting structure 4 undergoes elastic deformation and generates a first force.

[0053] As an example, the elastic element can be a tension spring. A first connecting shaft 310 can be provided on the first bracket 31, and a second connecting shaft 330 can be provided on the second bracket 33. One end of the second connecting structure 4 is connected to the first connecting shaft 310, and the other end is connected to the second connecting shaft 330. (See...) Figure 6 and Figure 7 As shown.

[0054] When the user puts on or takes off the device, the second support 33 rotates relative to the first support 31 in a first direction (i.e., the direction in which the wearing unit 2 is away from the ear) under the action of an external force. At this time, the tension spring is stretched and produces elastic deformation, thereby accumulating elastic potential energy. After the external force is removed, the elastic potential energy accumulated by the tension spring is converted into a restoring force, that is, a first force opposite to the first direction is applied to the second support 33, driving the second support 33 to rotate the wearing unit 2 toward the ear, so that the wearing unit 2 gently adheres to the surface of the user's auricle.

[0055] Unlike traditional methods that use rigid structures (such as relying solely on the clamping force of the headband 1) to forcibly press the ear shell 22 onto the auricle, this embodiment utilizes the flexible tension provided by a tension spring to create an "adaptive" characteristic in the fit between the wearing unit 2 and the auricle: when gaps exist between the wearing unit 2 and the auricle due to individual differences (such as differences in auricle thickness and angle), the tension spring allows the wearing unit 2 to automatically compensate for these gaps; when the pressure on the auricle is excessive, the second support 33 can overcome some of the tension and produce a slight retraction, avoiding localized pressure concentration. Therefore, this embodiment, while ensuring a good seal between the ear pad 21 and the auricle (improving passive noise cancellation performance), significantly reduces the pressure on the auricle, facilitating painless and fatigue-free long-term wear.

[0056] Of course, the elastic element in this embodiment is not limited to a tension spring. It can also be a torsion spring, an elastic rubber element, or other elements that can provide elastic restoring force, as long as it can generate elastic deformation when the second bracket 33 rotates in the first direction and apply a force to the second bracket 33 in the opposite direction of rotation.

[0057] like Figure 1 and Figure 2 As shown, in some embodiments, the wearing unit 2 may include an ear pad 21 for fitting against the auricle of the ear. The ear pad 21 may be either an ear-pressing type or an ear-buttoning type. An ear-pressing type can be understood as pressing against the ear; an ear-buttoning type can be understood as covering the ear.

[0058] When the ear pad 21 is an on-ear type, the ear pad 21 in this embodiment can adopt a contour-following structure design, and its thickness is non-uniformly distributed in the circumferential direction. Specifically, taking the user in a standing or normal sitting position as a reference, the thickness of the portion of the ear pad 21 that fits against the lower part of the auricle is greater than the thickness of the portion of the ear pad 21 that fits against the upper part of the auricle. For ease of description, the ear pad 21 can be defined as having an upper end and a lower end along the vertical direction of the human body when in use: when the user wears the wearable device, the upper end of the ear pad 21 corresponds to the upper part of the auricle (i.e., near the upper edge of the helix), and the lower end of the ear pad 21 corresponds to the lower part of the auricle (i.e., near the earlobe area).

[0059] like Figure 9 As shown, in this embodiment, the lower end thickness A of the ear pad 21 is greater than the upper end thickness B, and there is a preset thickness difference Δ (Δ = A - B) between them. This thickness difference Δ can be set according to ergonomic data to adapt to the auricular tilt angle of different races and age groups. Through this thickness difference, the ear pad 21 can naturally form a tilt angle C (i.e., the angle between the contact surface of the ear pad 21 and the vertical direction of the human body) when it fits against the auricle. This tilt angle C matches the natural tilt angle B of the outer ear relative to the head. This ensures that the ear cap matches the auricular angle, resulting in more even force distribution, avoiding excessive local pressure while achieving a snug seal, improving passive sealing performance, and thus enhancing wearing comfort and passive noise reduction performance.

[0060] In addition, the ear pad 21 in this embodiment can be made of high-density memory foam or similar materials. This material has good resilience and softness, and can adaptively adjust to the shape of the auricle when worn, reducing pressure on the ear and improving comfort during long-term wear.

[0061] To enhance wearing stability, the ear pad 21 of this embodiment may be further provided with a fitting surface on the side facing the auricle. This fitting surface is arc-shaped or curved and is adapted to the outer contour shape of the auricle.

[0062] like Figure 1 and Figure 2 As shown, in some embodiments, the wearing unit 2 may further include an ear shell 22. The ear shell 22 is generally shell-shaped, with the side facing the user's auricle being the inner side and the side away from the auricle being the outer side. The ear shell 22 forms an accommodating space for accommodating at least a portion of the first connecting structure 3, and optionally accommodating acoustic components (such as speaker units, circuit boards, batteries, etc.).

[0063] The ear pad 21 is mounted on the ear shell 22 and is fixedly positioned on the side of the ear shell 22 facing the user's auricle, i.e., the inner side of the ear shell 22. The ear pad 21 can be detachably or non-detachably connected to the ear shell 22 by means of adhesive, snap-on, magnetic attraction, or sewing. The detachable connection method allows users to replace the ear pad 21 with different thicknesses according to their personal needs, or to clean and maintain the ear pad 21.

[0064] The first connecting structure 3 is located inside the ear shell 22 and connects the ear shell 22 and the headband 1. By placing the first connecting structure 3 inside the ear shell 22, the appearance of the headphones can be made simpler, reducing exposed mechanical structures.

[0065] In some embodiments, the first connecting structure 3 is slidably connected to the headband 1 and fixedly connected to the wearing unit 2. The first connecting structure 3 can drive the wearing unit 2 to slide along the extension direction of the headband 1.

[0066] For example, the two ends of the head beam 1 can be provided with slide rails (not shown in the figure) or slide grooves respectively, and the first connecting structure 3 is provided with corresponding sliders (not shown in the figure) or slide grooves.

[0067] In some embodiments, to prevent the first connecting structure 3 from dislodging from the end of the head beam 1 during sliding, a limiting block (not shown in the figure) may be provided at the end of the slide groove, and a corresponding limiting flange (not shown in the figure) may be provided on the sliding part. When sliding to the maximum adjustment position, the limiting flange abuts against the limiting block to form a limiting protection.

[0068] like Figure 4 As shown, when the first connecting structure 3 includes a first rotating shaft 32, the first rotating shaft 32 can be used for sliding connection of the head beam 1. For example, one end of the first rotating shaft 32 can be provided with a slider that matches the slide groove. The slider is embedded in the slide groove and can slide freely along the length of the slide groove. The other end can be used for rotating connection of the first bracket 31.

[0069] In some embodiments, the first connecting structure 3 and the headband 1 can also be connected by a tension structure. One end of the tension structure is connected to the headband 1, and the other end is connected to the first connecting mechanism. The length of the headband 1 in the vertical direction can be adjusted to accommodate users with different head sizes, allowing the headphones to fit the head better and the ear pads 21 to cover the ears more tightly, thereby enhancing the passive sealing effect, reducing the entry of external sound and the leakage of internal sound, and also improving wearing comfort, avoiding discomfort caused by headphones being too tight or too loose.

[0070] For example, the tensioning mechanism may include a nested telescopic tube, wherein an inner tube is provided at the end of the head beam 1, and an outer tube is provided on the first connecting structure 3 to slide in conjunction with the inner tube. The inner tube can slide axially within the outer tube to change the overall length. To achieve damping and positioning effects during the sliding process, a damping element, such as a rubber ring, friction plate, or ball spring structure, can be provided between the inner and outer tubes.

[0071] Or, such as Figure 3 As shown, in some embodiments, the first rotating shaft 32 can be connected to the headband 1 via a slider 5, with the slider 5 slidably connected to the headband 1, and the first rotating shaft 35 rotatably connected to the slider 3. For example, one end of the slider 5 is used for slidably connecting to the headband 1, and the other end is used for fixed connection to or integrally formed with the first rotating shaft 32, so that the first rotating shaft 32 can move along the length direction of the headband 1 together with the slider 5. At the same time, the wearing unit 2 can rotate relative to the headband 1 along with the first rotating shaft 32.

[0072] like Figure 8 As shown, in some embodiments, the headband 1 may further include a deformable portion 11 located in the central region and a fixing portion 12 located at the end of the deformable portion 11.

[0073] The deformable part 11 can expand or shrink in accordance with the changes in the user's head circumference. The deformable part 11 is the main elastic part of the headband 1 and is made of materials with good elastic deformation ability, such as engineering plastics (polycarbonate PC, acrylonitrile-butadiene-styrene copolymer ABS, PC / ABS alloy), carbon fiber composite materials or elastic metals (such as stainless steel, titanium alloy), etc.

[0074] The deformable portion 11 is generally arc-shaped, and its curvature matches the contour curve from the top of the human head to the sides of the head. The core of the deformable portion 11 in this embodiment is that one or more deformation gaps 110 are provided inside or on its surface. The deformation gaps 110 can adapt to the expansion or contraction of the deformable portion 11 so that the pressure of the headband 1 on the user's head is evenly distributed.

[0075] For example, when the user's head circumference is large, the deformable part 11 expands outward, the width of the deformable gap 110 decreases, and the deformable part 11 as a whole tends to flatten to accommodate the larger head size. When the user's head circumference is small, the deformable part 11 contracts inward, the width of the deformable gap 110 increases, and the deformable part 11 as a whole tends to bend to accommodate the smaller head size.

[0076] As an example, the deformation gap 110 in this embodiment can be a hollow groove or an open slot formed on the deformation part 11. Furthermore, multiple deformation gaps 110 are arranged along the extending direction of the head beam 1, dividing the deformation part 11 into multiple interconnected elastic arms or elastic segments.

[0077] The fixing part 12 serves as the connection interface between the deformable part 11 and the first connecting structure 3, and is typically used in conjunction with a sliding connection structure. For example, the fixing part 12 may be provided with a slide rail or slide groove to form a sliding engagement with the sliding part on the first connecting structure 3, thereby realizing the relative position adjustment between the headband 1 and the first connecting structure 3. This ensures the universality of the wearable device among different users and the comfort of wearing it, avoiding the problem of being too tight or too loose due to the fixed length of the headband 1.

[0078] In some embodiments, the headband 1 further includes a flexible pad (not shown in the figure), which can be disposed on the inner side of the deformable portion 11 of the headband 1, i.e., the side facing the user's head. The flexible pad can improve the comfort and fit when wearing the head. In addition, it can also play a certain role in cushioning, reducing the impact of the headband on the head when the head moves or is subjected to slight external force, thereby improving the overall stability and safety of wearing the head.

[0079] The flexible pad is roughly strip-shaped and is arranged along the extension direction of the headband 1, covering the main areas where the headband 1 contacts the top of the head and the sides of the head.

[0080] As an example, flexible pads can be made from flexible materials such as slow-rebound memory foam, high-elasticity polyurethane foam, silicone, or thermoplastic elastomers (TPE). Different material choices can provide different levels of hardness, resilience, and breathability to meet the needs of different product positioning.

[0081] Furthermore, in this embodiment, the flexible pad and the deformable part 11 of the headband 1 can be fixed in various ways. For example, they can be fixed by adhesive bonding, wrapping, snap fasteners or Velcro, or integral molding.

[0082] In some embodiments, the thickness of the flexible pad can be designed non-uniformly according to the pressure-sensitive areas of the human head. For example, the top of the head (top of the headband 1) is a pressure concentration area, and a thicker flexible pad can be provided to increase cushioning; the sides of the head (both ends of the headband 1) are areas where clamping force is applied, and a medium thickness can be provided; the ends of the headband 1 (near the ears) can be provided with a thinner thickness to avoid excessively affecting the fitting angle of the wearing unit 2.

[0083] It should be noted that the order of the above embodiments of the present invention is merely for descriptive purposes and does not represent the superiority or inferiority of the embodiments. The processes depicted in the accompanying drawings do not necessarily require a specific or sequential order to achieve the desired result. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0084] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
