Description
An adjustable adaptive headband device Technical Field
[0001] This utility model relates to the field of headband-type equipment technology, and in particular to an adjustable and adaptive headband-type equipment. Background Technology
[0002] Over-ear headphones, also known as headband headphones, are a type of headband-style device, distinct from in-ear earbuds. Traditional over-ear headphones typically house the speaker drivers within a headband that wraps around the ears. While generally more ear-friendly than in-ear earbuds, prolonged wear can still cause noticeable pressure on the ears, and poor heat dissipation results in suboptimal comfort. Furthermore, traditional over-ear headphones are usually fixed or only slightly adjustable, offering insufficient fit for different head shapes. Additionally, the speaker drivers and headband are typically integrated into traditional over-ear headphones and cannot be disassembled, making headband cleaning (washing) inconvenient. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a headband device that can be easily adjusted to fit different head shapes, thereby improving the user experience.
[0004] To achieve the above objectives, this utility model provides an adjustable adaptive headband device, including a headband assembly, a connecting assembly, a support assembly, and an execution assembly;
[0005] The headband assembly includes a headband body and a main unit. The headband body is made of a soft material, and the main unit is connected to the headband body. The headband body is provided with a connection groove.
[0006] The connection assembly includes a first connector and a second connector. The first connector is made of a soft material. A first end of the first connector passes through the connection slot into the interior of the headband body and connects with the host. A second end of the first connector passes through the connection slot out of the headband body and connects with the second connector. The second connector is detachably connected to the headband body and the connection position can be adjusted.
[0007] The support assembly includes a support arm containing a memory material, a first end of the support arm being connected to the second connector, and a second end of the support arm being connected to the actuation assembly.
[0008] Furthermore, the headband body is worn around the forehead and back of the head, and the headband body is connected to a fitting part that fits the forehead.
[0009] Furthermore, both the outer surface of the headband body and the inner surface of the second connector are provided with Velcro, and the second connector is detachably connected to the headband body through the Velcro.
[0010] Furthermore, the first end of the first connector is provided with multiple wire guide slots and solder pads with solder joints. The second end of the first connector is provided with a POGPIN connector, and the contacts of the POGPIN connector are electrically connected to the solder joints of the solder pads through the internal circuitry of the first connector.
[0011] Furthermore, the first end of the first connector is provided with a locking slot, and a locking head is installed in the locking slot. The portion of the locking head protruding from the locking slot makes the width of the first end of the first connector greater than the width of the connecting slot.
[0012] Furthermore, the second end of the first connector is provided with an insertion guide groove, the second connector is provided with a keyway corresponding to the insertion guide groove, the second end of the first connector is also provided with a groove, and the second connector is provided with a protrusion corresponding to the groove, wherein the protrusion and the groove are fitted with an interference fit.
[0013] Furthermore, the memory material of the support arm is a metal memory wire, which is wrapped in a soft material, and the support arm also contains wiring.
[0014] Furthermore, the execution component includes an earphone body, within which a sound-generating unit and a controller are disposed. The controller is used to control the sound-generating unit, and a touch button is disposed on the earphone body, the touch button being electrically connected to the controller.
[0015] Furthermore, the earphone body is provided with electrodes for electroencephalogram (EEG) acquisition, and the electrodes contact the skin to acquire EEG signals from the skin surface.
[0016] Furthermore, in the first stage of the wearing process, the earphone body is further away from the side of the face, and the earphone body and the support arm are in a relaxed state. Angle α represents the tilt angle of the earphone body relative to the vertical direction, angle β represents the tilt angle of the earphone body relative to the front-back direction of the head, and distance L represents the distance of the earphone body relative to the second connector in the left-right direction of the head. In the second stage of the wearing process, the earphone body is partially fitted to the side of the face, distance L decreases, and the support arm has undergone compression deformation. Under the combined action of the reaction force from the side of the face and the elasticity of the support arm, angle α gradually decreases. In the third stage of the wearing process, distance L further decreases, the support arm is further compressed, and angle α of the earphone body relative to the second connector decreases. The vertical angle α is further reduced, and the β angle of the earphone body relative to the front-back direction of the head is further reduced. The earphone body adaptively fits the side face of the user. In the fourth stage of the wearing process, the distance L is further reduced, the support arm (15) is further compressed, and when the electrode (19) and the side face are subjected to force, there is a mechanical tendency for the two planes to be parallel to each other. Within the elastic range of the support arm (15), the plane of the electrode (19) and the plane of the side face will remain parallel to each other. The support arm (15) maintains mechanical balance through its own deformation. The angle α remains unchanged. The earphone body (16) adaptively keeps fitting the side face. The second connector maintains a preset distance from the side face.
[0017] The support arm has a first end and a second end, which are respectively fixed to the second connector and the headphone body. The L1 distance is defined as the horizontal distance from the leftmost part of the support arm to the first end. The L2 distance is defined as the horizontal distance between the first end and the second end of the support arm. The L3 distance is defined as the vertical distance between the first end and the second end of the support arm. The γ angle is defined as the angle between a straight section of the support arm in the headphone body and the horizontal direction. The L4 distance is defined as the distance between the leftmost part of the support arm and the first end.
[0018] The α angle, β angle, γ angle, L distance, L1 distance, L2 distance, L3 distance, and L4 distance all have preset design values.
[0019] The above-mentioned solution of this utility model has the following beneficial effects:
[0020] The adjustable adaptive headband device provided by this utility model, through the arrangement of the headband assembly and connecting assembly, allows the first and second connectors of the connecting assembly to be easily installed, removed, and adjusted in position relative to the headband body, thereby adapting to different head shapes. The use of soft materials enhances user comfort, and this quick-release design also facilitates cleaning. More specifically, the Velcro closure solves the problems of front-to-back adjustment and quick release, and the support strength is proven sufficient, ensuring product viability. This specific design of the first connector allows for a thinner and lighter design, and the insertion method with the main unit and the second connector is convenient and reliable. Combined with other fixing and limiting structures, it meets product requirements, reduces product costs, and ensures product performance and aesthetics, thus enhancing market competitiveness.
[0021] In this invention, the earphone body of the execution component utilizes the high elastic deformation capability of the support arm and a specific 3D spatial structure design to ensure that, during wear, regardless of the user's head shape or the shape of their side face, the earphone can adaptively fit the side face, ensuring sound playback while guaranteeing good contact between the EEG acquisition electrodes and the skin.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0048] 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 application pertains.
[0049] As shown in Figure 1, an embodiment of this utility model provides an adjustable adaptive headband device, including a headband assembly, a connecting assembly, a supporting assembly, and an execution assembly. The headband includes a headband body 1, which is made of a soft material to fully cover the forehead area when worn, improving both the secure fit and user comfort. As can be seen from Figure 1, the headband assembly also includes a fitting part. Unlike common headband headphones in the prior art, in this embodiment, the headband body 1 is worn around the forehead and back of the head, thus further enhancing the coverage and comfort by fitting the user's forehead. Additionally, the headband assembly includes a main unit 2, which is preferably positioned at the center of the headband body 1, as shown in the figure, to minimize the use of valuable space on both sides.
[0050] In this embodiment, the connection component includes a first connector 3 and a second connector 4. The two connectors electrically connect the main unit 2 of the headband assembly to the execution component, enabling the main unit 2 to supply power and transmit signals to the execution component. The first connector 3 is also made of a soft material, such as braided material. The headband body 1 has a connecting groove 5. The first end of the first connector 3 passes through the connecting groove 5 into the headband body 1 and plugs into the main unit 2. The second end of the first connector 3 exits the connecting groove 5 from the headband body 1 and connects to the second connector 4. With the second connector 4 electrically connected to the execution component, an electrical connection is formed between the main unit 2 and the execution component.
[0051] It is worth mentioning that the first connector 3 itself is also designed as a long strip (flat shape), with most of the first connector 3 arranged inside the headband body 1, avoiding occupying external space of the headband body 1 and improving the compactness and aesthetics of the headband body 1 itself. The first connector 3 is made of soft material, so that the user will not feel any obvious foreign object on the forehead after wearing it.
[0052] In this embodiment, the second connector 4 is detachably connected to the outer surface of the headband body 1. After the second end of the first connector 3 is inserted into the second connector 4, both ends of the first connector 3 form a firm connection with the headband body 1. In one specific embodiment, Velcro 6 is provided at a preset position on the outer surface of the headband body 1 and on the inner surface of the second connector 4. The Velcro 6 forms a relatively firm connection between the inner surface of the second connector 4 and the outer surface of the headband body 1. It is understood that the Velcro 6 connection not only makes installation and removal relatively convenient for the user, but also minimizes the side space occupied. Preferably, the Velcro 6 is in the form of a rough-surface Velcro 6.
[0053] In this embodiment, the second connector 4 is connected to the support component, and the support component is connected to the actuation component to provide support and transmit signals in sequence. Therefore, adjusting the position of the second connector 4 can adjust the position of the actuation component relative to the headband body 1 as a whole, thereby making it easier to adjust to different head shapes. Since the second connector 4 is fixed to the headband body 1 by Velcro 6, setting the area of the Velcro 6 on the headband body 1 to be larger allows the second connector 4 to have more adjustment space.
[0054] In a preferred embodiment of this example, the connecting groove 5 is configured as an I-shape, so that the outer edge can cover the fabric part of the headband body 1 at the connecting groove 5 and be firmly connected to it, so as to achieve a stable effect while maintaining a good overall appearance.
[0055] As shown in Figure 2, in a preferred embodiment of this invention, the first end of the first connector 3 is provided with multiple wire slots 7, such as the three wire slots shown in Figure 2, and also with solder pads 8 having solder joints. As shown in Figure 4, the second end of the first connector 3 is provided with a POGPIN connector 9. The contacts of the POGPIN connector 9 are electrically connected to the solder joints of the solder pads 8 through the internal wiring of the first connector 3. Therefore, when the metal part in the wire slot 7 is connected to the host 2, communication can be achieved between the first connector 3 and the second connector 4. It should be noted that a flexible circuit board can be built into the interior of the first connector 3, which allows the first connector 3 to deform flexibly while ensuring communication.
[0056] As shown in Figure 5, in a preferred embodiment of this invention, the first end of the first connector 3 is provided with a locking slot 10, and a locking head 11 is installed in the locking slot 10 to prevent the first connector 3 from being completely pulled out of the headband body 1. Specifically, as shown in Figure 5, the portion of the locking head 11 protruding from the locking slot 10 makes the width of the first end of the first connector 3 greater than the width of the connecting slot 5. Therefore, the first end of the first connector 3 cannot pass through the connecting slot 5, thereby preventing the first connector 3 from being directly pulled out of the headband body 1 after the connection with the host 2 becomes loose. The locking head 11 is designed in an olive shape so that it can be installed in the locking slot 10 without slipping out, with only the end of the locking head 11 protruding from the locking slot 10.
[0057] As shown in Figure 3, in a preferred embodiment of this invention, the second end of the first connector 3 is further provided with an insertion guide groove 12, and the second connector 4 is provided with a keyway corresponding to the insertion guide groove 12. When the second end of the first connector 3 is inserted into the second connector 4, the keyway and the insertion guide groove 12 cooperate with each other to guide insertion and prevent shaking after insertion. Simultaneously, the second end of the first connector 3 is also provided with a groove 13, and the second connector 4 is provided with a protrusion corresponding to the groove 13. When the second end of the first connector 3 is inserted into the second connector 4, the protrusion and the groove 13 can engage with each other to achieve a locking effect. Preferably, the engagement between the protrusion and the groove 13 is an interference fit, employing a strong insertion and extraction design to allow for both insertion and extraction, while providing a certain locking effect after insertion.
[0058] In a preferred embodiment of this invention, a transition band 14 is further provided at the second end of the first connector 3. The transition band 14 is used to gradually thin the second end of the first connector 3 towards the center, so that the thickness of the first connector 3 at the center is smaller. Preferably, the front side of the first connector 3 remains flat, and the back side is transitioned by the transition band 14, so as to improve the overall appearance.
[0059] As shown in Figures 6 and 7, in this embodiment, the execution component is connected to the second connector 4 via a support component. The support component includes a support arm 15, which employs a multi-layered structure, including soft materials and metal memory wire. For example, the soft material can be silicone, and the metal memory wire can be nickel-titanium alloy memory wire. Therefore, the support arm 15 can be adjusted to different (spatial) postures and held in place to maintain a suitable distance and angle between the execution component and the user's ear (or other parts of the face), providing the user with a comfortable experience. It should be noted that the support arm 15 also contains embedded wiring, which connects to the execution component to transmit signals.
[0060] In this embodiment, a headband-type device is described using a headband-type headset as an example. Therefore, the execution component includes a headset body 16, within which a sound-producing unit and a controller are disposed. After receiving a signal from the host 2, the controller controls the sound-producing unit to produce sound. The controller can also adjust the volume of the sound-producing unit and switch playback, for example, by directly touching the touch button 17 on the headset body 16. Of course, a controller may not be provided, and the sound-producing unit can be directly controlled through the host 2. Furthermore, when the headband-type device is a device with other functions, the execution component can also be provided accordingly.
[0061] In a preferred embodiment, the headphone body 16 also includes foam 18 at the sound-generating unit location. This foam covers the exposed portion of the sound-generating unit, providing contact cushioning and enhancing wearing comfort. Furthermore, the headphone body 16 can be further equipped with electrodes 19 for electroencephalogram (EEG) acquisition. These electrodes contact the skin to collect EEG signals from the skin surface, thereby monitoring the user's condition. In one specific embodiment, the electrodes 19 are made of copper plated with gold.
[0062] As mentioned above, the support arm 15 uses a soft material to wrap a metal memory wire. Through specific spatial adjustments, the headphone body 16 can achieve an adaptive fit during wearing and is suitable for most different head shapes.
[0063] Figure 8 shows a front view of the first stage of wearing the headband headphones. For ease of explanation, a simplified diagram is used, and the auricle is omitted. At this time, the headphone body 16 is far from the side of the face, and the headphone body 16 and the support arm 15 are in a relaxed state. Angle α represents the tilt angle of the headphone body 16 relative to the vertical direction (assuming the user is standing on a horizontal plane, the same applies below). Distance L represents the distance of the headphone body 16 relative to the second connector 4 in the left-right direction of the head. Figure 9 shows a front view of the second stage of wearing the headband headphones. At this time, the headphone body 16 has partially conformed to the side of the face, the distance L has decreased, and the metal memory wire in the support arm 15 has undergone a certain degree of compression deformation. Under the combined action of the reaction force of the side of the face and the elasticity of the metal memory wire, the angle α of the headphone body 16 gradually decreases. In the front view of the third stage of wearing the headband headphones shown in Figure 10, the distance L has further decreased, the metal memory wire in the support arm 15 has been further compressed, and the angle α of the headphone body 16 relative to the vertical direction has further decreased. At this time, the headphone body 16 fits the user's side of the face perfectly. In the front view of the fourth stage of the headband headphone wearing process shown in Figure 11, the distance L is further reduced, and the metal memory wire inside the support arm 15 is further compressed. Since the electrode 19 is planar, when the plane of the electrode 19 and the side face plane are subjected to mutual force, considering that the metal memory wire supporting the plane of the electrode 19 is a deformable material, there is a mechanical tendency for the two planes to be parallel and attached to each other. Within a certain elastic range of the metal memory wire, the plane of the electrode 19 and the side face plane will remain parallel and attached, and the metal memory wire maintains mechanical balance through its own deformation. Within this adaptive contact range, the α angle of the headphone body 16 in the vertical direction remains basically unchanged, and the headphone body 16 just adaptively maintains contact with the side face. At this time, the second connector 4 is still a small distance away from the side face because, in actual wear, the second connector 4 is blocked by the headband body 1 and hair. In addition, in the top view of the first stage of the headband headphone wearing process shown in Figure 12, the β angle is the tilt angle of the headphone body 16 relative to the front-back direction of the head. At this time, the headphone body 16 has not yet contacted the side face. Figure 13 is a top view of the third stage of the headband headphone wearing process. Similar to the above, the headphone body 16 is further reduced in angle β relative to the front-back direction of the head, and the plane of the headphone body 16 fits perfectly against the side of the face. Figure 14 is a top view of the fourth stage of the headphone wearing process. Although the distance is further reduced, the headphone body 16 can still maintain a parallel fit with the side of the face, and the angle β remains basically unchanged.
[0064] In summary, during the third and fourth stages of earphone wearing, the metal memory wire maintains mechanical balance during the reduction of the L-distance through its own deformation, ensuring that the plane of electrode 19 remains parallel and in close contact with the side of the face, demonstrating self-adaptive capabilities. Therefore, even when different individuals wear the earphones, despite variations in the side profile and the compression distance of the metal memory wire, the plane of electrode 19 consistently maintains parallel contact with the side of the face, achieving excellent EEG acquisition results.
[0065] In this embodiment, considering that electrode 19 needs to fit against the side of the face, as shown in Figure 17, electrode 19 is made larger in planar size, and the transition is closer to the plane of the headphone body 16. The larger contact plane brings better electrical contact effect, and the larger contact plane has a better force distribution effect, less local pressure when sleeping on the side, and better comfort. Figure 15 illustrates the definition of angle α in the physical structure. The final state of the headband headphones is that the plane of electrode 19 fits against the side of the face, so the angle relative to the vertical direction is taken as the contact plane of electrode 19. Similarly, Figure 16 illustrates the definition of distance L in the physical structure, and Figure 17 illustrates the definition of angle β in the physical structure, specifically the angle between the plane where electrode 19 is located and the front-back direction of the head.
[0066] In the half-sectional view of the earphone body 16 and the second connector 4 shown in Figure 18, the support arm 15 has two ends, namely the first end and the second end. The first end and the second end are fixed to the second connector 4 and the earphone body 16, respectively, to prevent relative displacement and rotation during use. The distance L1 is defined as the horizontal distance from the leftmost part of the support arm 15 to the first end in this view; the distance L2 is defined as the horizontal distance between the first end and the second end of the support arm 15 in this view; the distance L3 is defined as the vertical distance between the first end and the second end of the support arm 15 in this view; and the angle γ is defined as the angle between the straight portion of the support arm 15 within the earphone body 16 and the horizontal direction. The larger this angle, the more the earphone body 16 tilts to the upper right, affecting the wearing effect. In Figure 19, the distance L4 is defined as the distance between the leftmost part of the support arm 15 and the first end in this view.
[0067] The above parameters serve the following purposes: The distance L affects the depth of the earphone body 16. If the distance L is too small, the electrode 19 may not fit snugly against the side of the face; if the distance L is too large, it will affect the pressure of the electrode 19 on the side of the face after wearing. With the same diameter and material of the metal memory wire, a larger distance L results in greater pressure, affecting comfort. Furthermore, a larger distance L requires a larger angle α, because a larger distance L means a larger rotation angle of the earphone body 16 in the α direction during wear. To ensure the earphone body 16 remains snugly against the side of the face without lifting, although the plane of the electrode 19 has some ability to resist the rotational force of the earphone body 16, it is necessary to appropriately increase the angle α to alleviate potential lifting issues. The distances L1 and L2 affect the rotational force of the headphone body 16 in the β-angle direction during wearing. A larger L distance requires appropriately increasing both L1 and L2 distances to ensure the support arm 15 has sufficient deformable portion. Simultaneously, the ratio of L1 to L2 distances should be adjusted to ensure the force on both sides of the headphone body 16 is as balanced as possible, preventing excessive rotational torque in the β-angle direction and causing the headphone body 16 to warp. The L3 distance affects the vertical distance of the headphone body 16 relative to the auricle after the headband headphones are properly worn. If the L distance increases, the L3 distance should be appropriately decreased because during wearing, the deformation of the support arm 15 will push the headphone body 16 downwards relative to the auricle. A larger L distance results in a greater downward movement, while reducing the L3 distance ensures that the headphone body 16's sound unit remains located in the auricular region, achieving better sound reproduction. The distance L4 cannot be too small. During the wearing of the headband headphones, as the support arm 15 deforms, a distance that is too small will easily cause the support arm 15 to make preferential contact with the side of the face, and the interference electrode 19 to make contact with the side of the face. If the distance L4 is too large, it has no practical mechanical significance and affects the appearance, so it cannot be too large either.
[0068] Therefore, by designing appropriate parameters such as α angle, β angle, γ angle, L distance, L1 distance, L2 distance, L3 distance, and L4 distance, the 3D spatial shape of the support arm 15 can be controlled so that during the wearing of the headband headphones, while ensuring the sound playback effect, the electrodes 19 on the headphone body 16 can adaptively fit the side of the face and be suitable for most people's head shapes.
[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0070] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
