Description

Technical Field

[0001] The present invention relates to the technical field of headband type devices, and in particular to an adjustable and self-adaptive headband type device. Background Art

[0002] Headband headphones, or headphones on the head, are a type of headband device, which is different from in-ear earplugs. Traditional headband headphones usually insert the sound unit into a headband, and then wrap the headband around the ears. Although it is friendlier to the ears than in-ear earplugs, wearing it for a long time will still cause a noticeable sense of pressure on the ears, and the heat dissipation effect is poor, and it is difficult to achieve good comfort. At the same time, traditional headband headphones are usually fixed or adjusted in a small range, and the adaptation effect for different head shapes is still not good enough. In addition, the sound unit and headband of traditional headband headphones are usually combined together and do not support disassembly, so it is inconvenient to clean the headband (wash with water). Summary of the Invention

[0003] The purpose of the present invention is to address the deficiencies in the above-mentioned background technology and provide a headband device that can be easily adjusted to fit different head shapes, so as to improve the user experience.

[0004] In order to achieve the above-mentioned object, the present invention provides an adjustable and adaptive headband device, comprising a headband assembly, a connecting assembly, a supporting assembly, and an executing assembly;

[0005] The headband assembly includes a headband body and a host, wherein the headband body is made of soft material, the host is connected to the headband body, and the headband body is provided with a connecting groove;

[0006] The connecting assembly includes a first connector and a second connector, wherein the first connector is made of a soft material, a first end of the first connector passes through the connecting slot into the interior of the headband body and is connected to the host, and a second end of the first connector passes through the connecting slot out of the headband body and is connected to the second connector, and 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 memory material, a first end of the support arm is connected to the second connector, and a second end of the support arm is connected to the actuator assembly.

[0008] Furthermore, the headband body is worn around the forehead and the back of the head, and the headband body is connected to a fitting portion, which fits the forehead.

[0009] Furthermore, the outer surface of the headband body and the inner surface of the second connector are both provided with Velcro, and the second connector is detachably connected to the headband body via the Velcro.

[0010] Furthermore, the first end of the first connector is provided with multiple wire grooves and a soldering pad with solder points. 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 points of the soldering pad through the circuit inside the first connector.

[0011] Furthermore, a clamping head slot is provided at the first end of the first connector, a clamping head is installed in the clamping head slot, and the portion of the clamping head exposed from the clamping head 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 also provided with an insertion guide groove, the second connector is provided with a key groove corresponding to the insertion guide groove, the second end of the first connector is also provided with a groove, the second connector is provided with a protrusion corresponding to the groove, and the protrusion and the groove are fitted in an interference fit.

[0013] Furthermore, the memory material of the support arm is a metal memory wire, the metal memory wire is wrapped by a soft material, and a circuit is also provided in the support arm.

[0014] Furthermore, the execution component includes an earphone body, a sound unit and a controller are provided in the earphone body, the controller is used to control the sound unit, and a touch button is provided on the earphone body, and the touch button is electrically connected to the controller.

[0015] Furthermore, the earphone body is provided with electrodes for collecting EEG signals, and the electrodes are in contact with the skin to collect EEG signals on the skin surface.

[0016] Furthermore, in the first stage of the wearing process, the earphone body is farther away from the side face, and the earphone body and the support arm are in a relaxed state. The angle α represents the inclination angle of the earphone body relative to the vertical direction, the angle β represents the inclination angle of the earphone body relative to the front-back direction of the head, and the 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 has partially fitted the side face, the distance L becomes smaller, and the support arm has been compressed and deformed. Under the combined action of the reaction force of the side face and the elastic force of the support arm, the angle α of the earphone body gradually decreases; in the third stage of the wearing process, the distance L becomes further smaller, the support arm is further compressed, and the earphone body is relatively The α angle in the vertical direction is further reduced, and the β angle of the earphone body relative to the front-back direction of the head is further reduced, and the earphone body is adaptively fitted to the side face of the user; in the fourth stage of the wearing process, the L distance is further reduced, and the support arm (15) is further compressed. When the electrode (19) and the side face are subjected to mutual force, there is a tendency for the two planes to be parallel to each other in mechanics.

Distance L4 is defined as the distance between the leftmost portion of the support arm and the first end.

[0018] Angle α, angle β, angle γ, L distance, L1 distance, L2 distance, L3 distance, and L4 distance all have preset design values.

[0019] The above solution of the present invention has the following beneficial effects:

[0020] The adjustable and adaptive headband device provided by the present invention, through the arrangement of the headband assembly and the connecting assembly, enables the first connector and the second connector of the connecting assembly to be easily installed, removed, and adjusted relative to the headband body, thereby adapting to different head shapes. The use of soft materials improves the user's comfort, and the quick-release form is also convenient for cleaning.

DETAILED DESCRIPTION

[0044] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0048] Unless defined otherwise, 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 belongs.

[0049] like Figure 1 As shown, an embodiment of the present invention 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 so that the headband body 1 can fully wrap around the forehead when worn by the user, thereby improving the wearing firmness and making the user feel very comfortable. Figure 1 As can be seen in the figure, the headband assembly also includes a fitting portion. Unlike conventional headband headphones, the headband body 1 in this embodiment is designed to wrap around the forehead and back of the head. Therefore, the fitting portion fits the user's forehead, further enhancing the fit and comfort. Furthermore, the headband assembly also includes a main unit 2, which is preferably placed in the center of the headband body 1, as shown in the figure, to minimize the precious space on either side.

[0050] In this embodiment, the connection component includes a first connector 3 and a second connector 4. The host 2 of the headband assembly is electrically connected to the actuator through the two connectors, so that the host 2 can be powered and transmit signals to the actuator. The first connector 3 is also made of a soft material, such as a woven material, and a connection slot 5 is provided on the headband body 1. The first end of the first connector 3 passes through the connection slot 5 into the interior of the headband body 1 and is plugged into the host 2. The second end of the first connector 3 passes through the connection slot 5 and is connected to the second connector 4 after passing through the headband body 1. When the second connector 4 is electrically connected to the actuator, an electrical connection is formed between the host 2 and the actuator.

[0051] It's worth noting that the first connector 3 itself is also designed as a long strip (flat) overall, with the majority of the first connector 3 positioned inside the headband body 1, avoiding occupying external space and improving the compactness and aesthetics of the headband body 1. The first connector 3 is made of a soft material, ensuring that the user doesn't feel a noticeable foreign object on their forehead when 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 plugged into the second connector 4, both ends of the first connector 3 are securely connected to 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. Velcro 6 forms a relatively secure connection between the inner surface of the second connector 4 and the outer surface of the headband body 1. It is understood that connection via Velcro 6 not only makes installation and removal relatively convenient for the user, but also minimizes the use of side space. Preferably, Velcro 6 is in the form of a fleece-surface Velcro 6.

[0053] In this embodiment, the second connector 4 is connected to the support assembly, which in turn is connected to the actuator assembly, providing support and signal transmission. Therefore, adjusting the position of the second connector 4 adjusts the actuator assembly's position relative to the headband body 1, making it easier to adjust to different head shapes. Because the second connector 4 is secured to the headband body 1 via Velcro 6, a larger Velcro 6 area on the headband body 1 provides more room for adjustment for the second connector 4.

[0054] In a preferred implementation of this embodiment, the connecting groove 5 is configured to be I-shaped, so that the outer edge can cover the fabric portion of the headband body 1 at the connecting groove 5 and be firmly combined with it, achieving a stable effect while maintaining a good overall appearance.

[0055] At the same time Figure 2As shown, in a preferred implementation of this embodiment, the first end of the first connector 3 is provided with a plurality of wire grooves 7, for example Figure 2 The three wire slots 7 shown are also provided with pads 8 having solder points thereon. Figure 4 As shown, the second end of the first connector 3 is provided with a POG pin connector 9. The contacts of the POG pin connector 9 are electrically connected to the solder points of the pads 8 via the circuit inside the first connector 3. Therefore, when the metal portion in the wire channel 7 is connected to the host 2, communication with the second connector 4 can be achieved through the first connector 3. 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 be flexibly deformed as a whole while ensuring communication.

[0056] At the same time Figure 5 As shown, in a preferred embodiment of this embodiment, a clamping head slot 10 is provided at the first end of the first connector 3, and a clamping head 11 is installed in the clamping head slot 10, which is used to prevent the first connector 3 from being completely pulled out of the headband body 1. Figure 5 As shown, the portion of the clamping head 11 exposed from the clamping head 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 clamping head 11 is configured in an olive shape so that it can be installed in the clamping head slot 10 without moving out, and only the end of the clamping head 11 is exposed from the clamping head slot 10.

[0057] At the same time Figure 3 As shown, in a preferred implementation of the present embodiment, 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 key groove corresponding to the insertion guide groove 12. When the second end of the first connector 3 is plugged into the second connector 4, the key groove and the insertion guide groove 12 cooperate with each other to guide the insertion and prevent shaking after insertion. At the same time, the second end of the first connector 3 is further provided with a groove 13, and the second connector 4 is provided with a convex point corresponding to the groove 13. When the second end of the first connector 3 is inserted into the second connector 4, the convex point and the groove 13 can fit together to achieve the purpose of locking. Preferably, the cooperation between the convex point and the groove 13 is an interference fit, and a strong insertion and strong pull-out design method is adopted to achieve both insertion and pull-out, and a certain locking effect is achieved after insertion.

[0058] In a preferred embodiment of this embodiment, a transition band 14 is further provided at the second end of the first connector 3. The transition band 14 is used to gradually reduce the thickness of the second end of the first connector 3 toward the middle, thereby reducing the thickness of the middle portion of the first connector 3. Preferably, the front surface of the first connector 3 remains flat, and the back surface is transitioned by the transition band 14 to improve the overall appearance.

[0059] At the same time Figure 6 、 Figure 7 As shown, in this embodiment, the actuator is connected to the second connector 4 via a support assembly. The support assembly includes a support arm 15, which adopts a multi-layer structure, including a soft material and a metal memory wire. For example, the soft material can be a silicone material, and the metal memory wire can be a nickel-titanium alloy memory wire. Therefore, the support arm 15 can be adjusted to different (spatial) postures and maintained so that the actuator and the user's auricle (or other parts of the face) are kept at a suitable distance, angle, etc., so that the user feels very comfortable. It should be noted that a circuit is also embedded in the support arm 15, and the actuator is connected via the circuit to achieve the purpose of transmitting signals to the actuator.

[0060] In this embodiment, the headband device is described using a headband headset as an example. Therefore, the execution component includes a headset body 16, which houses a sound-generating unit and a controller. The controller receives signals from the host 2 and controls the sound-generating unit to generate sound. The controller can also adjust the volume of the sound-generating unit and switch playback, for example, by directly touching the touch buttons 17 on the headset body 16. Of course, the controller can also be omitted, and the sound-generating unit can be controlled directly through the host 2. Furthermore, if the headband device has other functions, corresponding execution components can also be provided.

[0061] As a preferred embodiment, the headphone body 16 of this embodiment is further provided with foam 18 at the location of the sound generating unit. This foam 18 is used to wrap the exposed portion of the sound generating unit, providing a contact cushioning effect and making it more comfortable to wear. Furthermore, the headphone body 16 can be further provided with electrodes 19 for EEG acquisition. These electrodes contact the skin to collect EEG signals from the skin surface, thereby monitoring the user's condition. In one embodiment, the electrodes 19 are made of gold-plated copper.

[0062] As mentioned above, the support arm 15 is in the form of a metal memory wire wrapped in a soft material. Through specific spatial adjustments, the earphone body 16 can achieve an adaptive fit effect during wearing, and is suitable for most different head shapes.

[0063] Figure 8 The figure shows a front view of the first stage of the headband headphone wearing process. For ease of illustration, a simplified diagram is used, and the auricle is not depicted. At this point, the headphone body 16 is relatively far from the side of the face, and the headphone body 16 and support arm 15 are generally in a relaxed state. Angle α represents the inclination of the headphone body 16 relative to the vertical direction (assuming the user is standing on a horizontal surface; the same applies to the following). Distance L represents the distance between the headphone body 16 and the second connector 4 in the left-right direction of the head. Figure 9The figure shows a front view of the second stage of the headband headphone wearing process. At this time, the headphone body 16 has partially fitted the side of the face, the distance L has become smaller, and the metal memory wire in the support arm 15 has been compressed and deformed to a certain extent. Under the combined action of the reaction force from the side of the face and the elastic force of the metal memory wire, the angle α of the headphone body 16 gradually decreases. Figure 10 In the front view of the third stage of the headband headphone wearing process, the distance L is further reduced, the metal memory wire in the support arm 15 is further compressed, and the angle α of the headphone body 16 relative to the vertical direction is further reduced. At this time, the headphone body 16 just fits the side of the user's face adaptively. Figure 11 In the front view of the fourth stage of the wearing process of the headband headphone shown, the L distance is further reduced, and the metal memory wire in the support arm 15 is further compressed. Since the electrode 19 is arranged in a plane, 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 tendency for the two planes to fit parallel to each other mechanically. 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 fit, and the metal memory wire maintains mechanical balance through its own deformation. Within this adaptive fitting range, the α angle of the headphone main body 16 in the vertical direction remains basically unchanged, and the headphone main body 16 just adaptively keeps fitting on the side face. At this time, the second connector 4 is still a small distance away from the side face. This is because in actual wearing, there is a barrier between the second connector 4 and the side face by the headband body 1 and the hair. In addition, Figure 12 In the top view of the first stage of the headband headphone wearing process, the angle β is the inclination angle of the headphone body 16 relative to the front-to-back direction of the head. At this time, the headphone body 16 has not yet touched the side of the face. Figure 13 This is a top view of the third stage of the headband headphone wearing process. Similar to the above, the angle β of the headphone body 16 relative to the front-to-back direction of the head is further reduced, and the plane of the headphone body 16 just fits the side of the face. Figure 14 This is a top view of the fourth stage of the earphone wearing process. Although the distance is further reduced, the earphone body 16 can still maintain a parallel fit with the side of the face, and the β angle remains basically unchanged.

[0064] In summary, during the third and fourth stages of the headphone wearing process, the metal memory wire maintains mechanical balance as the L distance decreases through its own deformation, allowing the plane of electrode 19 to always maintain parallel contact with the side of the face, demonstrating adaptive capabilities. Therefore, when worn by different people, despite the different side facial conditions and different compression distances of the metal memory wire, the plane of electrode 19 always maintains parallel contact with the side of the face, achieving good EEG collection results.

[0065] In this embodiment, considering that the electrode 19 needs to fit the side of the face, Figure 17 As shown, the electrode 19 is made larger in plane size and is closer to the plane of the earphone body 16. The larger contact plane brings better electrical contact effect, and the larger contact plane is better in force dispersion effect, which reduces the local pressure when sleeping on the side and improves comfort. Figure 15 The definition of angle α in the physical structure is explained. The final state of the headband headset is that the plane of the electrode 19 is in contact with the side of the face, so the angle relative to the vertical direction is taken as a reference. Similarly, Figure 16 The definition of L distance in physical structure is explained. Figure 17 The definition of angle β in the physical structure is explained, specifically the angle between the plane where the electrode 19 is located and the front-to-back direction of the head.

[0066] exist Figure 18 In the half-section view of the earphone body 16 and the second connector 4 shown, the support arm 15 has two ends, namely the first end and the second end. The first end and the second end are respectively fixed to the second connector 4 and the earphone body 16 to prevent relative displacement and rotation during use. The L1 distance is defined as the horizontal distance from the leftmost part of the support arm 15 to the first end in this view, the L2 distance is defined as the horizontal distance between the first end and the second end of the support arm 15 in this view, the L3 distance is defined as the vertical distance between the first end and the second end of the support arm 15 in this view, and the γ angle is defined as the angle between a straight part of the support arm 15 in the earphone body 16 and the horizontal direction in this view. The larger the angle, the more the earphone body 16 tilts toward the upper right corner, which affects the wearing effect. Figure 19 In the figure, the L4 distance is defined as the distance between the leftmost portion of the support arm 15 and the first end in this view.

[0067] The functions of the above parameters are as follows: the L distance affects the depth of the earphone body 16. If the L distance is too small, the electrode 19 will not fit the side of the face; if the L distance is too large, it will affect the pressing force of the electrode 19 on the side of the face after wearing. When the diameter and material of the metal memory wire are the same, the greater the L distance, the greater the pressure, which affects the comfort. In addition, the larger the L distance, the larger the α angle is required, because the larger the L distance, the greater the rotation angle of the earphone body 16 in the α direction during wearing. In order to ensure that the earphone body 16 can keep fitting the side of the face without warping, although the plane of the electrode 19 has a certain ability to resist the rotation force of the earphone body 16, it is necessary to appropriately increase the α angle to alleviate the possible warping problem. The L1 distance and the L2 distance affect the rotational force of the earphone body 16 in the β-angle direction during wearing. When the L distance is larger, the L1 distance and the L2 distance should be appropriately increased to allow the support arm 15 to have a sufficient deformable part. At the same time, the ratio of the L1 distance and the L2 distance should be adjusted to make the force on both sides of the earphone body 16 as balanced as possible to avoid excessive rotational torque of the earphone body 16 in the β-angle direction, which causes warping. The L3 distance affects the vertical distance of the earphone body 16 relative to the auricle after the headband earphones are worn. If the L distance increases, the L3 distance should be appropriately reduced, because during wearing, as the support arm 15 deforms, it will push the earphone body 16 downward relative to the auricle. The larger the L distance, the greater the amplitude of the downward movement, and reducing the L3 distance allows the sound unit of the earphone body 16 to remain in the auricle area, achieving a better sound playback effect. The L4 distance cannot be too small. During headband wear, as the support arm 15 deforms, a too small L4 distance can easily cause the support arm 15 to preferentially contact the side of the face, causing the interference electrode 19 to contact the side of the face. If the L4 distance is too large, it has no practical mechanical significance and affects the appearance, so it should also be kept small.

[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 is controlled, so that when the headband headphones are worn, the electrodes 19 on the headphone body 16 can adaptively fit the side of the face while ensuring the playback effect, and can adapt to the head shape of most people.

[0069] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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 merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
