head-mounted device

Abstract

The present invention discloses a head-mounted device, comprising: a host; and a wearable device connected to the host, the wearable device including an acoustic device and a harness, the harness for supplying power to the host. The wearable device further includes a spacer layer located between the acoustic device and the harness, the spacer layer being a high-permeability material layer. In a head-mounted device according to an embodiment of the present invention, the high-permeability spacer layer is disposed between the acoustic device and the harness in the wearable device. This spacer layer can affect the distribution of magnetic field lines around the harness through the attraction of its high permeability, significantly reducing the magnetic field strength near the harness, thereby reducing the varying Ampere force experienced by the harness and further reducing the vibration amplitude of the harness, thereby reducing noise problems caused by harness vibration. After the influence of the harness on the acoustic device is reduced, the probability of vibration noise from the acoustic device is also reduced.

[0004] For example, an increasing number of head-mounted devices are adopting a rear-mounted battery configuration to evenly distribute the weight of the head-mounted device and improve user comfort. However, this configuration separates the battery from the distal host unit, requiring power supply wiring to be placed within the head-mounted device's wearer, connecting the battery to the distal host unit and enabling the head-mounted device to display screen information to the wearer.

[0041] The following detailed description of the embodiments of the present invention is provided in the drawings, and examples of the embodiments are shown in the drawings, and like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout the drawings. The embodiments described below with reference to the drawings are illustrative and are only intended to help understand the present invention, and should not be construed as limiting the present invention.

[0042] In the description of the present invention, unless otherwise clearly specified and limited, the terms "attached," "coupled," and "connected" should be understood in a broad sense, and may refer to, for example, a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate element, or internal communication between two elements. Those skilled in the art can understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0043] To facilitate understanding of the embodiments by those skilled in the art, certain terms will be interpreted.

[0044] (1) VCC stands for Volt Current Condenser and refers to the power supply voltage.

[0045] (2) GND stands for Ground, which means earthing.

[0046] (3) FPC stands for Flexible Printed Circuit, which means a flexible printed circuit board.

[0047] (4) FR4 is a flame-resistant material grade number, and refers to a type of material specification in which the resin material must undergo a burning state and then self-extinguish.

[0048] For example, if a VR integrated device uses a band as a wearable device and a rear-mounted battery configuration is selected, the battery must be connected to the front head-mounted host by wiring to supply power to the head-mounted host. Wiring is required to connect the front and rear hosts and batteries, and there are two types of wiring: one that passes above the head and the other that passes to the side of the head. When the battery line passes to the side, since a typical VR integrated device has one audio device on each side, the wiring inevitably ends up being directly adjacent to the audio device.

[0049] As shown in FIG. 1A , the wearable device includes a battery compartment for storing power, and a wire for connecting the power source to the host. When the wire is placed inside the wearable device of a head-mounted device, a speaker (i.e., an acoustic device) is provided on each side of the host, and the wire inevitably comes into contact with the speaker. See FIG. 1B for the specific local structure of the relative positions of the wire and the speaker. Furthermore, during the operation of the head-mounted device, the forward magnet in the speaker generates a static magnetic field, and the changing current flowing through the power supply wire generates a changing magnetic field. This causes the wire to generate vibration noise due to the driving force in the magnetic field, thereby affecting the user's experience.

[0050] If the acoustic device and the wiring are too close, a magnet is attached to the acoustic device, and there is a magnetic field around the magnet, so when electricity is passed through the wiring, it is equivalent to placing a current-carrying conductor in a magnetic field. A changing current also generates a changing magnetic field, and in turn, the changing current generates a changing Ampere force (to calculate Ampere force, take the example of a power line that is a straight conductor with a current I and length L, the magnitude of the Ampere force received in a magnetic field B of uniform strength is F = ILB sin α, where α is (I, B) and is the angle between the current direction and the magnetic field direction. Then, for the force received by a current of any shape in a magnetic field of non-uniform strength, the current is decomposed into multiple current elements IΔL, and the force in each current element is calculated. The magnetic field B can be considered to be a magnetic field of uniform strength, and the ampere force ΔF = IΔL·B sinα (the sum of these multiple ampere force vectors is the force experienced by the entire current). Therefore, current-carrying wires are subjected to ampere force in the magnetic field. The greater the changing current, the greater this ampere force. This ampere force drives the wires to vibrate and produce sound. The magnetic horn itself is also subjected to a reaction force from the ampere force, which drives the speaker to vibrate and produce sound. Current-carrying conductors are subjected to ampere force in the magnetic field, and changes in the magnetic field or current will change the magnitude of the ampere force. Battery lines are prone to vibrate and generate noise due to the changing ampere force. If the speaker is better fixed or relatively heavy, the wiring will vibrate more, and most of the noise in XR integrated devices is due to the vibration of the wiring during the current-carrying process.

[0051] Hereinafter, a head-mounted device 100 according to several embodiments of the present disclosure will be described with reference to FIG. 1C and FIGS.

[0052] In the embodiments of the present disclosure, the type of head-mounted device 100 is not limited and may be any device worn on a user's head, such as AR glasses (AR, Augmented Reality), an AR-integrated device, VR glasses (VR, Virtual Reality), a VR-integrated device, or an Extended Reality (XR) device. The XR device may be a VR device, an Augmented Reality (AR) device, or a Mixed Reality (MR) device. These devices are smart link devices between the virtual world and the real world, allowing users to view the real world and virtual content and exchange visual, auditory, and other information.

[0053] 1C, a head-mounted device 100 according to an embodiment of the present invention includes a host 10 and a wearable device 20, and the wearable device 20 is connected to the host 10. Generally, the host 10 is worn on the user's face, and the space enclosed between the wearable device 20 and the host 10 is the head-mounted space.

[0054] That is, when the head-mounted device 100 is worn by a user, the user's head is positioned within the head-mounted space, and the wearable device 20 and the host 10 are placed around the user's head.

[0055] For example, there are generally two wearing devices 20, and the two wearing devices 20 are located on both the left and right sides of the host 10. In this way, the host 10 and the two wearing devices 20 may be connected in a ring shape, covering the user's head and ensuring that the head-mounted device 100 is securely worn. Of course, this application does not exclude a solution in which only one wearing device 20 is installed on the head-mounted device 100. Furthermore, although the head-mounted devices 100 according to this application are described as being worn on a human body in the examples, this application does not exclude a solution in which the head-mounted device 100 is worn on an animal.

[0056] In describing the present invention, it should be understood that the orientations or positional relationships indicated by the terms "upper," "lower," "front," "rear," "left," "right," "length," "width," "thickness," "top," "bottom," "inside," "outside," etc. are orientations or positional relationships shown in the drawings, are intended merely to facilitate and simplify the description of the present invention, and do not indicate or imply that the referenced devices or elements necessarily have a particular orientation or must be constructed and operated in a particular orientation, and therefore should not be understood as limiting the present invention.

[0057] 1C, an acoustic device 50 and a harness (also called "wiring") 40 are provided within a mounting device 20. The mounting device 20 further includes a spacer layer 22, which is located between the acoustic device 50 and the harness 40, and which is a layer of a high magnetic permeability material.

[0058] To facilitate understanding of the solution of the present application, the interaction between the acoustic device 50 and the harness 40 and the principle of installation of the spacer layer 22 will be described below with reference to examples shown in the drawings.

[0059] 1C, when both the acoustic device 50 and the harness 40 are installed within the wearing device 20, the harness 40 is installed extending along the length of the wearing device 20, and a portion of the harness 40 is located near the acoustic device 50, and this portion of the harness 40 may even be directly attached to the acoustic device 50. Taking the example shown in FIGS. 2 and 3 as an example, a portion of the harness 40 is located near the acoustic device 50, with a gap between them. Because the distance between the two is too close, noise is likely to occur.

[0060] The noise is generated because a magnetic material is generally attached inside the acoustic device 50, generating a static magnetic field around the magnetic material. A current flows through the harness 40, and the current value changes depending on the usage conditions of the head-mounted device 100. The changing current generates a changing magnetic field around the harness 40. As shown in FIG. 3, the static magnetic field of the acoustic device 50 and the electromagnetic field of the harness 40 affect each other, and both the acoustic device 50 and the harness 40 are in a changing magnetic field.

[0061] The conductive portion of the harness 40 is a type of conductor, and a current-carrying conductor is subjected to a force in a magnetic field, which is expressed microscopically as Lorentz force and macroscopically as Ampere force, with a changing current generating a changing Ampere force. The larger the changing current, the larger the changing Ampere force that is generated, and the changing Ampere force drives the harness 40 to vibrate and produce sound. The acoustic device 50 with a magnetic body itself is subjected to a reaction force of the Ampere force, and the reaction force drives the acoustic device 50 to vibrate, generating noise.

[0062] Furthermore, since the harness 40 is relatively long, it is difficult to completely secure it. In one solution, the harness 40 is designed to have a certain amount of redundancy in its length to avoid poor contact due to excessive stress at the connection points at both ends of the harness 40. Furthermore, in one solution, in order to accommodate different users' wearing needs, the wearing device 20 must be flexible and the harness 40 must be able to deform along with the wearing device 20. This makes it difficult to completely secure the harness 40 and to avoid noise caused by vibration of the harness 40 in a changing magnetic field. Here, the principles and calculation methods for how a conductor generates an Ampere force in a changing magnetic field are both prior art and will not be specifically discussed here.

[0063] To solve this technical problem, the solution of the present disclosure proposes that a spacer layer 22 is installed in the mounting device 20, and the spacer layer 22 is located between the acoustic device 50 and the harness 40, as shown in FIG. 1C, and the spacer layer 22 is a high magnetic permeability material layer.

[0064] So-called high-permeability materials refer to magnetic materials with a permeability of approximately 100 or more. Such materials are required to have high permeability, large saturation magnetic induction, high resistance, low loss, and high stability.

[0065] Because the magnetic permeability of the high-permeability material layer is much greater than that of the surrounding air or general materials, when magnetic field lines pass through the space where the high-permeability material layer is located in a magnetic field, the magnetic field lines are more concentrated on the high-permeability material layer, thereby reducing the magnetic field line density in the vicinity of the high-permeability material layer and weakening the magnetic field strength in the vicinity. For example, in the example shown in Figure 4, assuming that the high-permeability material layer is formed as a block, in a static magnetic field where the magnetic field strength reaches H0, the magnetic permeability material layer attracts the magnetic field lines and allows them to pass through, thereby reducing the magnetic field strength in the middle region of the block to H1, and therefore the high-permeability material layer provides a certain level of magnetic shielding protection for the middle region.

[0066] Based on the above reasons, a high magnetic permeability material layer is provided between the acoustic device 50 and the harness 40 in the present application.

[0067] In the case of the acoustic device 50, the static magnetic field generated by its internal magnetic body is an important component for acoustic-electrical conversion. A high-permeability material layer is positioned between the acoustic device 50 and the harness 40. The high-permeability material layer does not change the magnetic circuit of the acoustic device 50 and has little effect on the internal magnetic field density distribution. The isolation of the high-permeability material layer reduces the effect on the acoustic device 50 of the alternating magnetic field generated when the current in the harness 40 changes, thereby reducing the vibration amplitude of the acoustic device 50. Furthermore, since the acoustic device 50 is relatively short in length relative to the harness 40 and can be easily fixed, vibration noise is less likely to occur when the acoustic device 50 is firmly connected.

[0068] In the case of the harness 40, a high-permeability material layer is provided on the side of the harness 40 facing the acoustic device 50, and the high-permeability material layer can significantly reduce the magnetic field strength in the vicinity of the high-permeability material layer. In particular, after being blocked by the high-permeability material layer, the effect of the static magnetic field of the acoustic device 50 on the harness 40 is significantly reduced.

[0069] It should be further explained here that conventional head-mounted devices have limited functions, the harness current value is small, the generated ampere force change is small, and the problems of harness vibration and noise are not noticeable, so people have not yet thought about how to reduce harness vibration noise.

[0070] Taking earphones as an example, a headphone has a battery installed in it, and the battery is connected to the audio devices on both sides of the headphone by wires, and the audio devices only have a sound-generating function, and the battery passes a current to the audio devices, the voltage and current of which are both relatively low, and the static magnetic field of the magnetic material in the audio devices is relatively weak, so that the function of such headphones is simple, and the influence of the magnetic field between the audio devices and the wires is small, so the wires are less likely to vibrate.

[0071] With the development of modern technology, the functions of head-mounted devices 100 are gradually increasing, and particularly in AR-integrated devices and VR-integrated devices, the host 10 is responsible for the main function of virtual reality, and the host 10 requires a very large current under certain conditions, and the acoustic device 50 has a relatively strong static magnetic field to match the virtual reality, so when the harness 40 and the acoustic device 50 are attached adjacent to each other, the mutual influence of the magnetic fields is likely to cause vibration problems in the harness 40. The solution of the present application is proposed to enable the head-mounted device 100 to solve problems that have arisen with the development of modern technology.

[0072] In the head-mounted device 100 according to an embodiment of the present invention, a spacer layer 22 made of a high-permeability material is disposed between the acoustic device 50 and the harness 40 in the wearing device 20. This spacer layer 22's high-permeability attraction influences the distribution of magnetic field lines around the harness 40, biasing the magnetic field lines in the harness 40 toward the high-permeability material layer. This reduces the amount of magnetic flux in the harness 40, significantly reducing the magnetic field strength in the vicinity of the harness 40, reducing the varying Ampere force received by the harness 40, and further reducing the vibration amplitude of the harness 40, thereby reducing noise problems caused by vibration of the harness 40. After the influence of the harness 40 on the acoustic device 50 is reduced, the probability of vibration noise being generated in the acoustic device 50 is also reduced.

[0073] In the present solution, the spacer layer 22 may include cold-rolled carbon steel sheet, which is an SPCC material. SPCC originally stood for "general-purpose cold-rolled carbon steel sheet and strip," and many countries and companies use it to directly refer to similar steel products they produce. When cold-rolled carbon steel sheet is used, its plasticity and toughness are relatively high, and it has good welding and cold pressing properties, but it does not suffer from temper embrittlement. It can be applied to parts that do not have a heavy load and have relatively high toughness requirements.

[0074] In the solution of the present application, the spacer layer 22 may include a silicon steel plate. As will be understood, a silicon alloy steel having a silicon content of 1.0 to 4.5% and a carbon content of less than 0.08% is called silicon steel. The spacer layer 22 uses a silicon steel plate, which has properties such as high magnetic permeability, low coercive force, and a large resistivity coefficient, and its hysteresis loss and eddy current loss are both small.

[0075] In the solution of the present application, the spacer layer 22 may include a permalloy plate. Permalloy refers to an iron-nickel alloy with a nickel content between 35% and 90%. The spacer layer 22 may include a permalloy plate and have high weak magnetic field permeability. Furthermore, the magnetic properties can be effectively controlled, the plasticity is excellent, and the spacer layer 22 can be processed into an ultra-thin ribbon and various shapes for use.

[0076] In the solution of the present application, the spacer layer 22 may include a nanocrystal plate. Nanocrystals refer to nanoscale crystals that are insoluble in water and are produced by packaging calcium, magnesium, bicarbonate, and other ions in water using high-energy polymer balls. Using a nanocrystal plate as the spacer layer 22 provides the advantages of high magnetic permeability and wide frequency characteristics.

[0077] In the solution of the present application, the spacer layer 22 may be one layer or at least two layers, and the actual thickness of each spacer layer 22 may be selected as needed.

[0078] When the spacer layer 22 is a single layer, the spacer layer 22 may be any one of a cold-rolled carbon steel sheet, a silicon steel sheet, a permalloy sheet, and a nanocrystalline sheet. When the spacer layer 22 is a multi-layer, the spacer layer 22 may be one or more of a cold-rolled carbon steel sheet, a silicon steel sheet, a permalloy sheet, and a nanocrystalline sheet. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0079] In the present application, the material of the spacer layer 22 is not limited to the above-mentioned materials, and other materials with high magnetic permeability may be selected.

[0080] In some embodiments, the acoustic device 50 and the harness 40 are both located within the wearing device 20, the acoustic device 50 has an output side and a background tone side facing each other, the output side of the acoustic device 50 is installed facing the head mount space, and the harness 40 is located on the background tone side of the acoustic device 50. Here, the acoustic device 50 and the harness 40 are both installed within the wearing device 20 and are protected by the wearing device 20, making assembly easy.

[0081] By placing the sound output side of the acoustic device 50 facing the head mount space, sound generated by the acoustic device 50 can travel a relatively short path to the user's ear, thereby reducing power consumption. By placing the harness 40 on the back tone side of the acoustic device 50, the harness 40 and the spacer layer 22 do not affect sound propagation, and after the spacer layer 22 is installed, the spacer layer 22 is located on the back tone side of the acoustic device 50, and therefore has a relatively small effect on the magnetic circuit of the acoustic device 50.

[0082] 1C , the wearing device 20 has a thickness, and the thickness direction of the acoustic device 50 coincides with the thickness direction of the wearing device 20, making the thickness of the acoustic device 50 relatively small, thereby enabling the wearing device 20 to be made thin. Opposite sides in the thickness direction of the acoustic device 50 are the sound output side and the background tone side, respectively. In this case, the harness 40 may be installed on the background tone side of the acoustic device 50, i.e., the harness 40 is located on the side of the acoustic device 50 that is farther from the head mounting space. In other words, the acoustic device 50 and the harness 40 are arranged in the wearing device 20 along the thickness direction of the wearing device 20.

[0083] In further embodiments, the acoustic device 50 may be mounted on the surface of the wearing device 20, or the sound output side of the acoustic device 50 may extend from the wearing device 20, but the harness 40 may be located within the wearing device 20. Alternatively, in some embodiments, the acoustic device 50 may be located within the wearing device 20, but the harness 40 may be fixed to the surface of the wearing device 20. None of these are limiting here.

[0084] Of course, the solution of the present application is not limited to this, and the harness 40 may be installed above or below the acoustic device 50. In this way, by installing the wearing device 20 in a flatter shape, the entire head-mounted device 100 can be made thinner.

[0085] Furthermore, a magnetic material is provided within the acoustic device 50, and the vertical projection of the spacer layer 22 on the back tone side of the acoustic device 50 covers at least the vertical projection of the magnetic material on the back tone side of the acoustic device 50. It should be noted that, due to the characteristics of the magnetic circuit of the magnetic material within the acoustic device 50, the magnetic circuit lines located on the back tone side and the sound output side of the acoustic device 50 are more densely packed. Because the acoustic device 50 needs to propagate sound on the sound output side, the spacer layer 22 is provided on the back tone side of the acoustic device 50, and its projection can cover the magnetic material, so that the magnetic shielding effect can be ensured even if the area of the spacer layer 22 is not large.

[0086] In the solution of the present application, the spacer layer 22 is preferably a solid plate, which has sufficient toughness and strength and is resistant to deformation and displacement, thereby ensuring the effect of reducing the magnetic field of the harness 40.

[0087] The solution of the present application is not limited to this. For example, the spacer layer 22 may be provided in a mesh-like shape, and the mesh-like spacer layer 22 may cover the acoustic device 50 or cover only the back tone side of the acoustic device 50.

[0088] In some embodiments, the spacer layer 22 is fixedly connected to the acoustic device 50. As will be appreciated, the harness 40 is relatively long and difficult to completely secure. By securing the spacer layer 22 to the acoustic device 50, at least the portion of the spacer layer 22 adjacent to the acoustic device 50 is fixed relative to the position of the acoustic device 50.

[0089] The purpose of installing the spacer layer 22 is to reduce vibration of the harness 40 by weakening the magnetic field effect between the acoustic device 50 and the harness 40. When the position of the acoustic device 50 is fixed relative to the harness 40 and at least the portion of the spacer layer 22 adjacent to the acoustic device 50 is fixed relative to the position of the acoustic device 50, the spacer layer 22 is held between the acoustic device 50 and the harness 40, helping to prevent the spacer layer 22 from moving to other positions along the length of the harness 40.

[0090] In one solution, if a skeleton is placed in the mounting device 20 and the acoustic device 50 is fixed relative to the position of the skeleton, the spacer layer 22 may be placed on the skeleton.

[0091] Specifically, the spacer layer 22 is fixed to the acoustic device 50 by adhesive bonding, which not only makes the fixing easier, but also saves time and effort and space.

[0092] Of course, in the solution of the present application, the spacer layer 22 may also be fixed in other ways, for example, by connecting with screws.

[0093] As mentioned above, in the present application, the spacer layer 22 may be one layer or may be arranged in at least two layers. When the spacer layer 22 is arranged in at least two layers, two adjacent spacer layers 22 may be arranged with a gap between them, or two adjacent spacer layers 22 may be arranged in close contact with each other. By flexibly arranging the spacer layer 22, various arrangements can be achieved according to the actual needs of the product.

[0094] 5, when the spacer layer 22 has at least two layers, the layers are a first spacer layer 221 and a second spacer layer 222, and the first spacer layer 221 has a higher magnetic permeability than the second spacer layer 222, and the second spacer layer 222 has a higher magnetic saturation than the first spacer layer 221. In other words, the spacer layer 22 is a type of build-up layer, and by providing a build-up layer material between the harness 40 and the acoustic device 50, the magnetic field strength near the harness 40 can be further reduced, thereby reducing noise caused by vibration of the harness 40. Furthermore, in this application, features defined by "first" or "second" may explicitly or implicitly include one or more of the features.

[0095] To explain the advantages of build-up layers, let's first analyze the magnetic performance of a single magnetically permeable material. Figure 6 shows the relationship between magnetic flux density and magnetic field strength for cold-rolled carbon steel sheet. When the magnetic field strength H of a cold-rolled carbon steel sheet increases gradually, its magnetic flux density B increases gradually first. When the magnetic field strength reaches a certain value, the magnetic flux density B tends to remain constant.

[0096] As known to those skilled in the art, magnetic permeability μ is equal to the ratio of magnetic induction strength B to magnetic field strength H in a magnetically permeable material, i.e., μ = B / H. Therefore, the magnetic permeability μ of cold-rolled carbon steel sheet changes under different magnetic field strengths, and the calculation formula for magnetic permeability μ is μ = ΔB / ΔH. When the magnetic field strength of cold-rolled carbon steel sheet is relatively low, the magnetic permeability μ is relatively large. When the magnetic field strength reaches a certain value, the magnetic permeability μ tends to zero, indicating that the cold-rolled carbon steel sheet is in a magnetic saturation state. That is, when magnetic saturation is not reached, the magnetic permeability μ of cold-rolled carbon steel sheet is relatively large, and when magnetic saturation is reached, the magnetic permeability μ of cold-rolled carbon steel sheet is relatively small.

[0097] As can be understood, it is difficult for a typical magnetically permeable material to maintain both the magnetic permeability and the magnetic saturation at relatively high parameters. When the magnetic saturation of a magnetically permeable material is relatively high, it is difficult to maintain the relatively high magnetic permeability of the magnetically permeable material. When the magnetic field of the magnetic material of the acoustic element is extremely strong, if only a high-permeability material layer with too high a magnetic permeability is used, the shielding function may be lost due to magnetic saturation.

[0098] In the solution of the present application, the spacer layer 22 is installed as a build-up layer and includes a first spacer layer 221 and a second spacer layer 222. At least two types of magnetically permeable materials are selected and combined, allowing the two materials to complement each other's deficiencies. The first spacer layer 221 has a higher magnetic permeability than the second spacer layer 222, and the second spacer layer 222 also has a higher magnetic saturation than the first spacer layer 221. Therefore, when used in combination, the first spacer layer 221 provides a relatively high magnetic permeability, and the second spacer layer 222 provides a relatively high magnetic saturation. In this way, good shielding function can be achieved when the magnetic field strength is relatively weak, and good shielding function can also be achieved when the magnetic field strength is relatively strong. This further reduces the probability of vibration of the harness 40 and reduces vibration noise.

[0099] Specifically, when the spacer layer 22 includes a first spacer layer 221 and a second spacer layer 222, the magnetic permeability of the first spacer layer 221 may be higher than that of the second spacer layer 222, and the first spacer layer 221 may be located on the side of the second spacer layer 222 adjacent to the acoustic device 50. The closer to the acoustic device 50, the more concentrated the magnetic field lines become, and therefore, after the second spacer layer 222 reduces the magnetic field strength, the high magnetic permeability of the first spacer layer 221 can be fully utilized.

[0100] When the number of spacer layers 22 is larger, they may be combined in multiple forms, and there is no limitation here. When the spacer layer 22 is a build-up layer, cold-rolled carbon steel thin plate, silicon steel plate, permalloy plate, or nanocrystalline plate may be selected and combined.

[0101] Specifically, when there are at least two spacer layers 22, two adjacent spacer layers 22 are connected to each other by adhesive, the harness 40 is connected onto the spacer layers 22 by adhesive, and the spacer layers 22 are connected to the acoustic device 50 by adhesive. The positions between adjacent spacer layers 22 can be fixed by adhesive fixation, all spacer layers 22 can be fixed to the acoustic device 50, and the harness 40 can be fixed to the spacer layers 22 at the adhesive locations. Here, not only is the overall structural strength relatively high, but a relatively strong shielding effect can also be maintained.

[0102] In the solution of the present application, the wearing device 20 may be belt-shaped and worn on both the left and right sides of the user's head, but of course the solution of the present application is not limited to this. For example, in one solution, the wearing device 20 is hat-shaped and worn on the top of the user's head. The wearing device 20 may be made of a soft material, which can be more comfortable to wear and have wider adaptability. The wearing device 20 may be made of a hard material, and the harness 40 is attached by providing a receiving chamber within the wearing device 20.

[0103] In some alternative embodiments, the wearing device 20 includes a mounting case and a band, the band is connected to the mounting case, and the acoustic device 50 is disposed within the mounting case, and the mounting case can protect the acoustic device 50, which is advantageous for ensuring the mounting reliability and stability of the acoustic device 50, thereby ensuring the use reliability of the head-mounted device 100.

[0104] 1C , according to some embodiments of the present invention, head-mounted device 100 further includes a battery unit 30, which is disposed opposite host 10, connected to the rear end of wearable device 20, and connected to the front end of wearable device 20, and the space surrounded by battery unit 30, wearable device 20, and host 10 is the head-mounted space. In other words, when head-mounted device 100 is worn by a user, the user's head is positioned within the head-mounted space, and battery unit 30, wearable device 20, and host 10 are disposed around the user's head.

[0105] In the solution of the present application, there are generally two wearing devices 20, and the two wearing devices 20 are located on both the left and right sides of the host 10. In this way, the host 10, the two wearing devices 20, and the battery unit 30 may be connected in a ring shape to cover the user's head, thereby ensuring that the head-mounted device 100 is securely worn. In some solutions, there is only one wearing device 20, i.e., the wearing device 20 is installed on only one side of the host 10 and the battery unit 30, thereby ensuring that the head-mounted device 100 is securely worn.

[0106] As an option, an elastic material is filled between the wearing device 20 and the harness 40. That is, a chamber is defined within the wearing device 20, and an elastic material is filled between the harness 40 and the wall of the chamber. As a further option, elastic materials are installed on both sides of the thickness of the wearing device 20, or the harness 40 is wrapped all around with elastic material, which can reduce the vibration amplitude of the harness 40 and further reduce noise.

[0107] Furthermore, other portions of the harness 40, excluding the portion adjacent to the acoustic device 50, may be secured with a soft adhesive. The soft adhesive may be selected from a variety of types, the main requirement being high viscosity and low hardness. Examples include silica gel and explosion-resistant cement. Specifically, this may be achieved by a liquid silicone rubber injection molding process, in which liquid silicone rubber is injected between the mounting device 20 and the harness 40, and after cooling and hardening, both sides or the entire harness 40 is covered with the soft adhesive.

[0108] FIG. 7 shows a schematic diagram of a harness 40 according to some embodiments of the present disclosure, and FIG. 8 shows a cross-sectional view of the harness 40.

[0109] As shown in Figures 7 and 8, the harness 40 includes a signal line 41, a signal conductor 411, a shielding layer 412, a first filling member 413, an earth wire 42, an earth conductor 421, a third filling member 422, a power line 43, a power conductor 431, a second filling member 432, and an outer sheath 44.

[0110] The structure of the head-mounted device 100 in a specific embodiment will be described below with reference to FIG. 1C and FIGS.

[0111] As shown in FIG. 1C , the head-mounted device 100 includes a host 10, a wearing device 20, and a battery unit 30. The host 10 is worn on the user's face, and the battery unit 30 is placed opposite the host 10 and worn on the back of the user's head. The front end of the wearing device 20 is connected to the host 10, and the battery unit 30 is connected to the rear end of the wearing device 20. An acoustic device 50 for outputting sound to a human ear is provided within the wearing device 20. The battery unit 30 has a harness 40, which is provided within the wearing device 20 and connected to the host 10. The wearing device 20 includes a spacer layer 22, which is located between the acoustic device 50 and the harness 40, and which is a high-magnetic-permeability material layer.

[0112] 9, acoustic device 50 includes top cover 51, diaphragm 52, voice coil 53, washer 54, magnet 55, casing 56, and casing frame 57, and acoustic device 50 is assembled as a flat cubic member, with the side of acoustic device 50 facing top cover 51 being the sound output side and the side facing casing frame 57 being the back tone side. Here, the materials of each member are not limited, and for example, top cover 51 and diaphragm 52 are composite material members, voice coil 53 and casing 56 are plastic members, and washer 54 and casing frame 57 are SPCC members.

[0113] Specifically, in the static magnetic field of the acoustic device 50, the north pole is located on the sound output side and the south pole is located on the back tone side. Fig. 10 shows a structural diagram of the back tone side of the acoustic device 50. Fig. 11 shows the structural diagram of the acoustic device 50 after a spacer layer 22 is installed on the back tone side. Fig. 12 shows the magnetic leakage simulation effect when the acoustic device 50 has a spacer layer 22 made of a different material attached.

[0114] In short, the head-mounted device 100 of the present invention can significantly reduce vibration noise of the harness 40 by providing the spacer layer 22 .

[0115] In some embodiments of the present disclosure, a harness is located in the power line assembly, and the harness includes at least one first conductor and at least one second conductor. Figure 13 shows an internal structural view of another harness 400 according to some embodiments of the present disclosure.

[0116] As shown in FIG. 13, the harness 400 includes at least one first conductor 4110 and at least one second conductor 4120 .

[0117] The noise occurs because magnetic materials are generally attached to components of the head-mounted device 100, generating a static magnetic field around the magnetic materials. Current flows through the harness 400, and the current value changes depending on the usage conditions of the head-mounted device 100. The changing current generates a changing magnetic field around the harness 400.

[0118] The conductive portion of the harness 400 is a type of conductor, and a current-carrying conductor is subjected to a force in a magnetic field, which is expressed microscopically as Lorentz force and macroscopically as Ampere force, and a changing current generates a changing Ampere force. The larger the changing current, the larger the generated Ampere force, which drives the harness 400 to vibrate and produce sound.

[0119] Furthermore, since the harness 400 is relatively long, to avoid excessive stress at the connection points at both ends of the harness 400, which can lead to poor adhesion, the harness 400 generally has a certain length redundancy when designed. Furthermore, in some solutions, in order to accommodate different users' wearing needs, the wearing device 20 must be flexible and the harness 400 must be able to deform along with the wearing device 20, which makes it difficult to completely fix the harness 400 and to avoid noise caused by vibration of the harness 400 in a changing magnetic field. Here, the principles and calculation methods for how a conductor generates an Ampere force in a changing magnetic field are both prior art and will not be specifically discussed here.

[0120] To solve this technical problem, in some embodiments of the present disclosure, as shown in FIG. 13, a first conductive wire 4110 is placed adjacent to at least one second conductive wire 4120, and / or a second conductive wire 4120 is placed adjacent to at least one first conductive wire 4110.

[0121] In the head-mounted device 100 according to an embodiment of the present invention, the first conducting wire 4110 and at least one second conducting wire 4120 are arranged adjacent to each other, and the second conducting wire 4120 and at least one first conducting wire 4110 are arranged adjacent to each other, thereby enabling the opposing Ampere forces received by the first conducting wire 4110 and the second conducting wire 4120 to be almost canceled out, thereby significantly weakening the force received by the harness 400, further reducing the vibration amplitude of the harness 400, and reducing noise problems caused by vibration of the harness 400.

[0122] In the present application, by installing a first conducting wire 4110 and at least one second conducting wire 4120 adjacent to each other, and by installing a second conducting wire 4120 and at least one first conducting wire 4110 adjacent to each other, the opposing Ampere forces received by the first conducting wire 4110 and the second conducting wire 4120 can be almost canceled out, thereby reducing the vibration amplitude of the harness 400, and after the influence of the harness 400 on the acoustic device 50 is reduced, the probability of vibration noise occurring in the acoustic device 50 is also reduced.

[0123] According to some embodiments of the present invention, one of the first conducting wire 4110 and the second conducting wire 4120 is a positive connecting wire, and the other of the first conducting wire 4110 and the second conducting wire 4120 is a negative connecting wire.

[0124] Specifically, the harness 400 connects the battery unit 30 and the host 10, so that the battery unit 30 can supply power to the host 10, with one of the first conductor 4110 and the second conductor 4120 being connected between the positive terminal of the battery unit 30 and the host 10, and the other of the first conductor 4110 and the second conductor 4120 being connected between the negative terminal of the battery unit 30 and the host 10.

[0125] The first conducting wire 4110 and the second conducting wire 4120 are respectively connected to the positive and negative electrodes of the battery unit 30. That is, when current is applied, the direction of current in the first conducting wire 4110 is opposite to the direction of current in the second conducting wire 4120, and therefore the first conducting wire 4110 and the second conducting wire 4120 are subjected to opposite Ampere forces. By arranging the first conducting wire 4110 and at least one second conducting wire 4120 adjacent to each other and by arranging the second conducting wire 4120 adjacent to each other, the opposite Ampere forces applied to the first conducting wire 4110 and the second conducting wire 4120 can be substantially canceled out, thereby significantly weakening the force applied to the harness 400 and further reducing the vibration amplitude of the harness 400 and reducing noise problems caused by vibration of the harness 400.

[0126] As shown in FIG. 13, according to some embodiments of the present invention, at least some of the first conductive wires 4110 and at least some of the second conductive wires 4120 are alternately arranged across the width of the mounting device 20.

[0127] For example, it may include one first conductive wire 4110 and one second conductive wire 4120, and the first conductive wires 4110 and the second conductive wires 4120 are alternately arranged in the width direction of the mounting device 20; further, for example, it may include one first conductive wire 4110 and multiple second conductive wires 4120, and the first conductive wire 4110 and at least one second conductive wire 4120 are alternately arranged in the width direction of the mounting device 20; even further, for example, it may include multiple first conductive wires 4110 and one second conductive wire 4120, and the second conductive wire 4120 and at least one first conductive wire 4110 are alternately arranged in the width direction of the mounting device 20.

[0128] In some embodiments, each may include a plurality of first conductive wires 4110 and a plurality of second conductive wires 4120, and in some of the plurality of first conductive wires 4110 and some of the plurality of second conductive wires 4120, one second conductive wire 4120 is provided between two adjacent first conductive wires 4110 and one first conductive wire 4110 is provided between two adjacent second conductive wires 4120.

[0129] The current directions of the first conducting wires 4110 and the second conducting wires 4120 that are close to each other are opposite, and the Ampere forces generated in the two are opposite according to the left-hand rule. The Ampere forces received by the first conducting wires 4110 and the second conducting wires 4120 that are close to each other are almost the same but in opposite directions, so that they can be almost canceled out. This greatly reduces the force received by the harness 400 and further improves the noise problem.

[0130] As shown in FIG. 13, in some embodiments, all of the first conductive wires 4110 and all of the second conductive wires 4120 are alternately arranged across the width of the mounting device 20.

[0131] In other words, all the first conductive wires 4110 and all the second conductive wires 4120 are arranged to form a single harness layer, the thickness direction of the single harness layer coincides with the thickness direction of the mounting device 20, the width direction of the single harness layer coincides with the width direction of the mounting device 20, and the length direction of the single harness layer coincides with the length direction of the mounting device 20, which not only improves the noise problem but also improves the utilization rate of the internal space of the mounting device 20 without changing the dimensions of the mounting device 20.

[0132] In some embodiments, the harness 400 includes multiple harness layers, which are arranged in the thickness direction of the mounting device 20, and at least some of the first conductors 4110 and at least some of the second conductors 4120 in each harness layer are arranged alternately in the width direction of the mounting device 20, thereby further ensuring that the forces applied to the first conductors 4110 and the second conductors 4120 can be offset, thereby improving noise issues.

[0133] For example, the harness 400 may include two harness layers, each including a plurality of first conductive wires 4110 and a plurality of second conductive wires 4120, and the plurality of first conductive wires 4110 and the plurality of second conductive wires 4120 in each harness layer may be alternately arranged in the width direction of the mounting device 20. Of course, the number of harness layers may be three or more, and may be adjusted according to the specific dimensions of the conductive wires and the mounting device.

[0134] The plurality of first conducting wires 4110 in two adjacent harness layers are arranged facing each other one-to-one, and the plurality of second conducting wires 4120 in two adjacent harness layers are arranged facing each other one-to-one, or the plurality of first conducting wires 4110 in two adjacent harness layers are arranged with a shift in the width direction of the wearing device 20, and the plurality of second conducting wires 4120 in two adjacent harness layers are arranged with a shift in the width direction of the wearing device 20. Specifically, this may be adjusted according to actual conditions.

[0135] Of course, one of the two harness layers may include one first conductive wire 4110, and the other harness layer may include one second conductive wire 4120, and the first conductive wire 4110 and the second conductive wire 4120 may be arranged in the thickness direction of the mounting device 20; or one of the two harness layers may include one first conductive wire 4110, and the other harness layer may include multiple second conductive wires 4120, and the multiple second conductive wires 4120 may be arranged in the thickness direction of the mounting device 20. Alternatively, one of the two harness layers may include a plurality of first conductive wires 4110 and the other harness layer may include one second conductive wire 4120, and the plurality of first conductive wires 4110 may be arranged side by side in the width direction of the mounting device 20, and the first conductive wire 4110 and the second conductive wire 4120 may be arranged side by side in the thickness direction of the mounting device 20.

[0136] In some embodiments, the number of first conducting wires 4110 and the number of second conducting wires 4120 may be equal or unequal. For example, the number of first conducting wires 4110 and the number of second conducting wires 4120 may both be three or four, or, for example, the number of first conducting wires 4110 may be three and the number of second conducting wires 4120 may be four, or, for example, the number of first conducting wires 4110 may be four and the number of second conducting wires 4120 may be three.

[0137] As shown in FIG. 14, according to another embodiment of the present invention, the harness 400 includes a first group of wires 4310 and a second group of wires 4320, and the first group of wires 4310 and the second group of wires 4320 are arranged in the thickness direction of the attachment device 20.

[0138] In some examples, the first group of wires 4310 includes one first conductive wire 4110. In other examples, the first group of wires 4310 includes a plurality of first conductive wires 4110, and the plurality of first conductive wires 4110 are arranged side by side in the width direction of the mounting device 20, such that the plurality of first conductive wires 4110 form the first group of wires 4310.

[0139] In some examples, the second group of wires 4320 includes one second conductive wire 4120. In other examples, the second group of wires 4320 includes a plurality of second conductive wires 4120, and the plurality of second conductive wires 4120 are arranged side by side in the width direction of the mounting device 20, such that the plurality of second conductive wires 412 form the second group of wires 43200.

[0140] In other words, all the first conductive wires 4110 and all the second conductive wires 4120 are arranged in two rows in the thickness direction of the mounting device 20, the first row including one or more first conductive wires 4110 arranged side by side in the width direction of the mounting device 20, and the second row including one or more second conductive wires 4120 arranged side by side in the width direction of the mounting device 20.

[0141] In an embodiment in which the first wire group 4310 includes a plurality of first conductive wires 4110 and the second wire group 4320 includes a plurality of second conductive wires 4120, the plurality of first conductive wires 4110 and the plurality of second conductive wires 4120 may be installed adjacent to each other in a one-to-one relationship in the thickness direction of the mounting device 20, and the ampere forces received by every two adjacent first conductive wires 4110 and second conductive wires 4120 are approximately equal but opposite in direction, so that the forces received by the harness 400 can be approximately canceled out, thereby reducing vibration and further improving noise issues.

[0142] As shown in FIG. 15, according to yet another embodiment of the present invention, a first conducting wire 4110 and at least one second conducting wire 4120 are arranged in a spirally crossing manner, i.e., the first conducting wire 4110 and at least one second conducting wire 4120 are wound around each other, and / or a second conducting wire 4120 and at least one first conducting wire 4110 are arranged in a spirally crossing manner, i.e., the second conducting wire 4120 and at least one first conducting wire 4110 are arranged in a spirally crossing manner, which not only ensures the compact arrangement of the first conducting wire 4110 and the second conducting wire 4120, but also cancels out the ampere force received by every two adjacent first conducting wires 4110 and second conducting wires 4120, thereby improving noise problems.

[0143] In some embodiments, the number of first conducting wires 4110 and the number of second conducting wires 4120 are equal, and the first conducting wires 4110 and the second conducting wires 4120 are arranged in a one-to-one correspondence, crossing each other in a spiral. That is, the first conducting wires 4110 and the second conducting wires 4120 are arranged in pairs, crossing each other in a spiral, thereby forming a multiple twisted pair structure.

[0144] Multiple twisted pair structures may be arranged side by side in the width direction of the mounting device 20, which not only improves noise issues but also improves the utilization rate of the internal space of the mounting device 20 while ensuring that the dimensions of the mounting device 20 do not change.

[0145] It should be noted that the arrangement of the plurality of first conductive wires 4110 and the plurality of second conductive wires 4120 according to the embodiment of the present invention may be set according to actual space needs, and is not specifically limited herein.

[0146] According to some embodiments of the present invention, a protective layer is provided on the outside of the first conducting wire 4110 and / or the second conducting wire 4120 itself, and the protective layer includes a rubber layer, a plastic layer, or a carbon fiber layer. For example, the protective layer may be specifically Teflon or TPE (thermoplastic elastomer), etc., and reduces the vibration amplitude of the first conducting wire 4110 and / or the second conducting wire 4120, further reducing noise.

[0147] 16 and 17, according to some embodiments of the present invention, an elastic material 60 is filled between the wearing device 20 and the harness 400. That is, a storage chamber 21 is defined within the wearing device 20, and the elastic material 60 is filled between the harness 400 and the wall surface of the storage chamber 21.

[0148] In some embodiments, the harness 400 has elastic material 60 on both sides of the thickness of the wearing device 20, or the harness 400 is wrapped around itself with elastic material 60, thereby reducing the vibration amplitude of the harness 400 and further reducing noise.

[0149] In some embodiments, the harness 400 may be secured with a soft adhesive. The soft adhesive may be selected from a variety of types, with the primary requirement being high viscosity and low hardness. Examples include silica gel and explosion-resistant cement. Specifically, this may be achieved by a liquid silicone rubber injection molding process, where liquid silicone rubber is injected between the mounting device 20 and the harness 400. After cooling and hardening, both sides or the entire harness 400 are covered with the soft adhesive.

[0150] FIG. 18 is a schematic diagram illustrating another head-mounted device 200 in accordance with at least one embodiment of the present disclosure.

[0151] As shown in FIG. 18, head-mounted device 200 includes host 110 and mounting device 120 .

[0152] The wearing device 120 includes a speaker (ie, an acoustic device) 130, a harness 150, and at least one reverse magnet 140, which repels a forward magnet in the acoustic device.

[0153] The host unit 110 is connected to the wearing device 120, and the wearing device 120 is provided with a speaker 130, at least one reverse magnet 140 that repels the forward magnet 131 in the speaker 130, and a conductor 150 for supplying power to the host unit 110 inside.

[0154] As shown in FIG. 19, the mounting device 120 includes a first mounting sub-unit 121 and a second mounting sub-unit 122 .

[0155] One end of the first mounting subunit 121 is fixedly connected to one end of the host unit 110, and the other end of the first mounting subunit 121 is fixedly connected to the other end of the host unit 110. A speaker 130, at least one reverse magnet 140 that repels the forward magnet 131 in the speaker 130, and a conductor 150 for supplying power to the host unit 110 are installed inside the first mounting subunit 121. One end of the second mounting subunit 122 is fixedly connected to the front end of the host unit 110, and the other end of the second mounting subunit 122 is fixedly connected to the middle position of the first mounting subunit 121.

[0156] For example, the first mounting sub-unit 121 is a ring mounting sub-unit and the second mounting sub-unit 122 is a top mounting sub-unit, specifically see Fig. 19. This allows the ring mounting sub-unit and the top mounting sub-unit to better secure the host unit 110 to the user's head.

[0157] For example, the first mounting sub-unit 121 and the second mounting sub-unit 122 can be selectively soft fixing bands, so that the soft fixing bands can better fix the host unit 110 to the user's head.

[0158] Furthermore, for example, the first mounting sub-unit 121 may have portions fixedly connected to both sides of the host unit 110 made of a hard material, and the remaining portions may be made of a soft fixing band. The second mounting sub-unit 122 may be made of a soft fixing band. This allows the speaker 130 and at least one reverse magnet 140, which repels the forward magnet 131 in the speaker 130, to be better installed on the hard material.

[0159] Furthermore, for example, the first mounting sub-unit 121 and the second mounting sub-unit 122 are optionally fixed units made of a hard material, and the fixed units made of a hard material are optionally arched, thereby forming a helmet shape, so that the user can use the helmet-shaped mounting device 120 to better fit the wearer's head.

[0160] In actual use, the head-mounted device operates by generating a static magnetic field in the forward magnet 131 of the speaker 130 located inside the wearing device 120. This generates a changing magnetic field due to the changing current flowing through the conductor 150. The conductor 150 is then driven by a force in the magnetic field, generating vibration noise. This force is the Lorentz force microscopically and the Ampere force macroscopically. The Ampere force is calculated by assuming the current is I and the length of the conductor 150 is L. The magnitude of the Ampere force experienced in a uniform magnetic field B is F=I*L*B*sinα, where α is (I, B) and represents the angle between the current direction and the magnetic field direction. The direction of the Ampere force is determined by the left-hand rule. For the force experienced by a current of any shape in a magnetic field of non-uniform strength, the current can be decomposed into multiple current components I*ΔL, and the magnetic field B at each current component can be regarded as a magnetic field of uniform strength, and the corresponding experienced ampere force ΔF=I*ΔL*B*sinα. Then, by adding all the ampere force vectors, the force experienced by the entire current can be obtained.

[0161] In other words, a changing current generates a changing Ampere force, and the greater the changing current, the greater the Ampere force, and the corresponding conductor 150 will generate vibration noise of different intensities due to the driving of different Ampere forces.

[0162] Based on the above reasons, some embodiments of the present disclosure install at least one reverse magnet 140 inside the wearing device 120 that repels the forward magnet 131 in the speaker 130, so that the head-mounted device uses the reverse magnet 140 to change the direction of the magnetic flux lines around the conductor 150 during operation, thereby reducing the amount of magnetic flux around the conductor 150, weakening the magnetic field strength around the conductor 150, and further reducing or eliminating the Ampere force driving the conductor 150, thereby achieving the purpose of reducing or eliminating the vibration noise generated by the conductor 150 driven by the Ampere force, thereby improving the user experience.

[0163] For more clarity, some embodiments of the present disclosure provide at least one reverse magnet 140 installed inside the mounting device 120 and the first mounting sub-unit 121, which changes the direction of magnetic flux lines around the conductor 150, thereby achieving the technical effect of reducing and even eliminating vibration noise generated by the conductor 150 being driven by Ampere force. Hereinafter, the installation form of the at least one reverse magnet 140 installed inside the first mounting sub-unit 121 will be described in detail with reference to FIGS. 20 to 26.

[0164] Considering that the number of at least one reverse magnet 140 may be one or more, based on Figures 20 and 21, we will first explain the installation form in which the reverse magnet 140 is installed inside the first mounting sub-unit 121 when the number of reverse magnets 150 is one.

[0165] The single structure of the speaker 130 includes a dust cover, a diaphragm, a voice coil, a washer, a magnet (forward magnet), a casing, and a casing, as shown in Figure 9. The dust cover and the diaphragm are made of composite materials, the voice coil and the casing are made of plastic materials, and the washer and the casing are made of SPCC (general-purpose cold-rolled carbon steel sheet and strip).

[0166] A rear view of the speaker 130 viewed from the casing is shown in Figure 26. As can be seen from Figure 26, the magnetic field of the forward magnet 131 in the speaker 130 facing the casing is the south pole (south magnetic pole). Therefore, as shown in Figure 20, in some embodiments of the present disclosure, one reverse magnet 140 may be installed on the outside of the casing of the speaker 130. In other words, the magnetic field of the reverse magnet 140 facing the casing is also the south pole.

[0167] 21 , in some embodiments of the present disclosure, when the portions of the first mounting subunit 121 that are fixedly connected to both sides of the host unit 110 are made of a hard material, or when the first mounting subunit 121 is a fixed unit made of a hard material, a groove is selectively carved at the same position on the first mounting subunit 121 based on the installation position of the speaker 130 on the first mounting subunit 121. Next, a reverse magnet 140 with a magnetism opposite to that of the forward magnet 131 on the speaker 130 is installed in the groove, thereby using the reverse magnet 140 to change the direction of the magnetic flux lines around the conductive wire 150. The groove on the first mounting subunit 121 faces the forward magnet 131 on the speaker 130.

[0168] Consider factors such as the dimensions of the forward magnet 131 and the reverse magnet 140 in the speaker 130. For example, if the size of the forward magnet 131 is larger than the size of one reverse magnet 140, in this embodiment, multiple reverse magnets 140 may be installed inside the first mounting sub-unit 121 to effectively change the direction of the magnetic flux lines around the conductive wire 150. See Figures 22 to 25 for details.

[0169] Hereinafter, the installation form of the multiple reverse magnets 140 installed inside the first mounting sub-unit 121 will be described in detail with reference to FIGS.

[0170] Referring to FIG. 22, in some embodiments of the present disclosure, a plurality of reverse magnets 140 may be arranged on the outside of the casing of the speaker 130 in sequence along the first direction.

[0171] Alternatively, referring to FIG. 23, some embodiments of the present disclosure may further include a plurality of reverse magnets 140 arranged on the outside of the casing of the speaker 130 in sequence along the second direction.

[0172] The first direction may be the horizontal direction or the vertical direction, and the corresponding second direction may be the vertical direction or the horizontal direction. In other words, when the first direction is the horizontal direction, the second direction is the vertical direction, and when the first direction is the vertical direction, the second direction is the horizontal direction. The vertical direction is, for example, the extension direction of the harness, and the horizontal direction is, for example, the direction perpendicular to the extension direction of the harness.

[0173] In some embodiments of the present disclosure, a reverse magnet 140 may further be installed in the groove of the first mounting subunit 121. Therefore, referring to FIG. 24 , in some embodiments of the present disclosure, a plurality of the reverse magnets 140 may be installed in the groove of the first mounting subunit 121 in sequence along the first direction.

[0174] Referring to FIG. 25, some embodiments of the present disclosure may further include a plurality of the reverse magnets 140 arranged in the groove of the first mounting sub-unit 121 in sequence along the second direction.

[0175] The position of the groove corresponds to the position of the speaker 130 installed in the first mounting sub-unit 121, and the groove faces the forward magnet 131 of the speaker 130.

[0176] In some embodiments of the present disclosure, the first direction may be horizontal or vertical, and the corresponding second direction may be vertical or horizontal, i.e., if the first direction is horizontal, the second direction is vertical, and if the first direction is vertical, the second direction is horizontal.

[0177] It should be noted that the number of the multiple reverse magnets 140 installed inside the first mounting sub-unit 121 shown in Figures 22 to 25 is merely illustrative, and the specific number may be flexibly adjusted according to the dimensions of the forward magnet 131, and is not specifically limited here.

By providing at least one reverse magnet that repels the forward magnet in the speaker inside the wearing device, the reverse magnet can be used to change the direction of magnetic flux lines around the power supply conductor, thereby weakening the magnetic field strength around the harness and further reducing or eliminating the force that drives the harness to move, thereby achieving the purpose of reducing or eliminating the vibration noise generated by the harness driving force, thereby effectively improving the user experience.

The fourth first earth wire 21121 is laid in the fourth second sub-wiring region from the left side of the second wiring region 2112, slanting leftward. The fifth first power supply wire 21111 is laid in the fifth first sub-wiring region from the left side of the first wiring region 2111, slanting leftward. The third first earth wire 21121 is laid in the fifth second sub-wiring area from the left side of the second wiring area 2112, slanting to the left, the sixth first power supply wire 21111 is laid in the sixth first sub-wiring area from the left side of the first wiring area 2111, and the sixth first earth wire 21121 is laid in the sixth second sub-wiring area from the left side of the second wiring area 2112, slanting to the left.

[0188] The first second power supply wire 21211 is laid in the first third sub-wiring region from the left side of the third wiring region 2121, slanting towards the right; the first second earth wire 21221 is laid in the first fourth sub-wiring region from the left side of the fourth wiring region 2122, slanting towards the right; the second second power supply wire 21211 is laid in the second third sub-wiring region from the left side of the third wiring region 2121, slanting towards the right; The second second earth wire 21221 is laid in the second fourth sub-wiring region from the left side of the fourth wiring region 2122, slanting towards the right; the third second power supply wire 21211 is laid in the third third sub-wiring region from the left side of the third wiring region 2121, slanting towards the right; the third second earth wire 21221 is laid in the third fourth sub-wiring region from the left side of the fourth wiring region 2122, slanting towards the right; The fourth second power supply wire 21211 is laid in the fourth third sub-wiring region from the left side of the third wiring region 2121, slanting towards the right; the fourth second earth wire 21221 is laid in the fourth fourth sub-wiring region from the left side of the fourth wiring region 2122, slanting towards the right; the fifth second power supply wire 21211 is laid in the fifth third sub-wiring region from the left side of the third wiring region 2121, slanting towards the right; The third second earth wire 21221 is laid slantingly to the right in the fifth fourth sub-wiring area from the left side of the fourth wiring area 2122, the sixth second power supply wire 21211 is laid slantingly to the right in the sixth third sub-wiring area from the left side of the third wiring area 2121, and the sixth second earth wire 21221 is laid slantingly to the right in the sixth fourth sub-wiring area from the left side of the fourth wiring area 2122.

[0189] In at least one embodiment of the present disclosure, in the entire wiring layer 210, the inclination directions of a certain first power supply line 21111 and a second power supply line 21211 at a corresponding position are opposite to each other, so that the current directions of the first power supply line 21111 and the second power supply line 21211 at a corresponding position are opposite to each other. Furthermore, the first power supply line 21111 is subjected to opposite Ampere forces from two directions, and therefore, the opposite Ampere forces from the two directions partially cancel each other out. Similarly, the inclination directions of a certain first earth line 21121 and a second earth line 21221 at a corresponding position are opposite to each other, so that the current directions of the certain first earth line 21121 and the second earth line 21221 at a corresponding position are opposite to each other. 1 and the second earth wire 21221 at the corresponding position are opposite in current direction, and furthermore, the first earth wire 21121 is subjected to opposite Ampere forces from two directions, and therefore, these opposite Ampere forces from the two directions are partially offset, thereby realizing a reduction in the vertical and horizontal vibration amplitude of the first power wire 21111, the second power wire 21211, the first earth wire 21121 and the second earth wire 21221. Therefore, compared to the related art, the noise generated when the power wires vibrate under the force in the magnetic field is significantly reduced, and further, user satisfaction is significantly improved.

[0190] As shown in FIGS. 27 to 29, the vertical cross sections of the first power supply line 21111 and the first earth line 21121 are parallelograms, and the vertical cross sections of the second power supply line 21211 and the second earth line 21221 are parallelograms.

[0191] Since both sides of the first sub-wiring layer 2101 are straight, both sides of the second sub-wiring layer 2102 are also straight, and therefore, in the case of the first power supply line 21111, the first earth line 21121, the second power supply line 21211 or the second earth line 21221 located at the edge, the shape of the vertical cross section is adjusted to some extent.

[0192] As shown in FIG. 30, in at least one embodiment of the present disclosure, the wiring structure further includes a first protective layer 3022, a second protective layer 3028, and a first insulating layer 3025. A first adhesive layer 3023 is provided between the first surface of the first sub-wiring layer 2101 and the first protective layer 3022, thereby adhering the first surface of the first sub-wiring layer 2101 to the first protective layer 3022; a second adhesive layer 3024 is provided on the second surface of the first sub-wiring layer 2101 and one side of the first insulating layer 3025, thereby adhering the second surface of the first sub-wiring layer 2101 to one side of the first insulating layer 3025; a third adhesive layer 3026 is provided on the third surface of the second sub-wiring layer 2102 and the other side of the first insulating layer 3025, thereby adhering the third surface of the second sub-wiring layer 2102 to the other side of the first insulating layer 3025; and a fourth adhesive layer 3027 is provided between the fourth surface of the second sub-wiring layer 2102 and the second protective layer 3028, thereby adhering the fourth surface of the second sub-wiring layer 2102 to the second protective layer 3028.

[0193] As shown in Figure 30, in at least one embodiment of the present disclosure, in order to achieve communication between the first sub-wiring layer 2101 and the second sub-wiring layer 2102, a first via 2113 is provided in the first sub-wiring layer 2101 and a second via 2123 is provided in the second sub-wiring layer 2102, and the first via 2113 and the second via 2123 can communicate between the first sub-wiring layer 2101 and the second sub-wiring layer 2102.

[0194] 31 , in at least one embodiment of the present disclosure, a head-mounted device 300 includes a host 4 and a power supply unit 3, and further includes the above-described wiring structure 2, one end of which is connected to the host 4 and the other end of which is connected to the power supply unit 3. Speakers 5 are provided on both sides of the host 4, close to the wiring structure 2.

[0195] Another aspect of the present disclosure provides a wiring method applied to the wiring structure 2 in FIGS.

[0196] As shown in FIG. 32, the wiring method includes steps S11 to S14.

The fifth second earth wire 21221 may be laid in the wiring area with a rightward incline, the fifth fourth sub-wiring area from the right side of the fourth wiring area 2122 with a rightward incline, the sixth second power supply wire 21211 may be laid in the sixth third sub-wiring area from the right side of the third wiring area 2121 with a rightward incline, and the sixth second earth wire 21221 may be laid in the sixth fourth sub-wiring area from the right side of the fourth wiring area 2122 with a rightward incline.

[0217] In at least one embodiment of the present disclosure, in the above wiring method, when the first direction in the first sub-wiring layer 2101 is a direction that slopes to the right, the first arrangement order is from right to left, and the first arrangement order in the second sub-wiring layer 2102 is from right to left, and the second direction is a direction that slopes to the left.

[0218] For example, six second power supply lines 21211 need to be laid in the third wiring area 2121, and six second earth lines 21221 need to be laid in the fourth wiring area 2122. In this case, first, the first second power supply line 21211 is laid in the first third sub-wiring area from the right side of the third wiring area 2121, slanting leftward, and the first second earth line 21221 is laid in the first fourth sub-wiring area from the right side of the fourth wiring area 2122, slanting leftward. the second second power line 21211 is laid in the second third sub-wiring area from the right side of the third wiring area 2121, slanting leftward; the second second earth line 21221 is laid in the second fourth sub-wiring area from the right side of the fourth wiring area 2122, slanting leftward; the third second power line 21211 is laid in the third third sub-wiring area from the right side of the third wiring area 2121, slanting leftward; the third second earth line 21221 is laid in the third fourth sub-wiring area from the right side of the third wiring area 2121, slanting leftward; The fourth second power wire 21211 is laid in the third fourth sub-wiring area from the right side of the wiring area 2122, slanting towards the left, the fourth second earth wire 21221 is laid in the fourth fourth sub-wiring area from the right side of the third wiring area 2121, slanting towards the left, the fourth second power wire 21211 is laid in the fourth fourth sub-wiring area from the right side of the fourth wiring area 2122, slanting towards the left, the fifth second power wire 21211 is laid in the fifth third sub-wiring area from the right side of the third wiring area 2121. The fifth second earth wire 21221 may be laid in the wiring area with a leftward incline, the fifth fourth sub-wiring area from the right side of the fourth wiring area 2122 with a leftward incline, the sixth second power supply wire 21211 may be laid in the sixth third sub-wiring area from the right side of the third wiring area 2121 with a leftward incline, and the sixth second earth wire 21221 may be laid in the sixth fourth sub-wiring area from the right side of the fourth wiring area 2122 with a leftward incline.

[0219] In at least one embodiment of the present disclosure, the first power lines 21111 and one first earth line 21121 are alternately arranged in parallel, and the second power lines 21211 and one second earth line 21221 are alternately arranged in parallel. This allows the first power lines 21111 and one first earth line 21121 to be adjacent to each other in the first sub-wiring layer 2101. For example, after a first power line 21111 is energized, the first power line 21111 and the adjacent first earth line 21121 are Since the currents in the first power supply line 21111 are the same in magnitude but opposite in direction, the first power supply line 21111 is subjected to opposing Ampere forces from two directions. Therefore, these opposing Ampere forces from the two directions partially cancel each other out, thereby reducing the horizontal vibration amplitude of the first power supply line 21111 and the first earth line 21121 in the first sub-wiring layer 2101 and further reducing noise caused by horizontal vibration of the first power supply line 21111 and the first earth line 21121.

[0220] Similarly, in the second sub-wiring layer 2102, each second power supply line 21211 and one second earth line 21221 are adjacent to each other. Taking one second power supply line 21211 as an example, after electricity is applied, the currents in the second power supply line 21211 and the adjacent second earth line 21221 are the same in magnitude but opposite in direction, so that the second power supply line 21211 is subjected to opposing Ampere forces from two directions. Therefore, these opposing Ampere forces from the two directions partially cancel each other out, thereby reducing the horizontal vibration amplitude of the second power supply line 21211 and the second earth line 21221 in the second sub-wiring layer 2102 and further reducing noise caused by horizontal vibration of the second power supply line 21211 and the second earth line 21221.

[0221] In step S14, the first sub-wiring layer 2101 and the second sub-wiring layer 2102 are bonded together, the first wiring region 2111 and the third wiring region 2121 are arranged to intersect with each other, and the second wiring region 2112 and the fourth wiring region 2122 are arranged to intersect with each other.

[0222] Bonding the first sub-wiring layer 2101 and the second sub-wiring layer 2102 includes arranging each of the first power lines 21111 and one of the second power lines 21211 to cross each other in an X-shape, and arranging each of the first earth lines 21121 and one of the second earth lines 21221 to cross each other in an X-shape.

[0223] In at least one embodiment of the present disclosure, by adhering the first sub-wiring layer 2101 and the second sub-wiring layer 2102 together, the first sub-wiring layer 2101 and the second sub-wiring layer 2102 can be fixed, and further, each first power line 21111 and the second power line 21211 at the corresponding position can be crossed and corresponded to each other.

[0224] In at least one embodiment of the present disclosure, each first power line 21111 is installed to cross one second power line 21211 at a corresponding position. Therefore, for example, after the first power line 21111 is energized, the current magnitude of the first power line 21111 and the second power line 21211 at the corresponding position are the same. However, since the inclination directions of the first power line 21111 and the second power line 21211 at the corresponding position are opposite, the current magnitude of the first power line 21111 and the second power line 21211 at the corresponding position are opposite. The current directions of the first power line 21111 and the second power line 21211 at the corresponding position are opposite to each other, and furthermore, the first power line 21111 is subjected to opposite Ampere forces from two directions. Therefore, the opposite Ampere forces from the two directions partially cancel each other out, thereby reducing the amplitude of the up and down vibration of the first power line 21111 and the second power line 21211, and further reducing the noise caused by the vertical vibration of the first power line 21111 and the second power line 21211.

[0225] Similarly, each first earth wire 21121 and one second earth wire 21221 at a corresponding position are installed crossing each other. Therefore, taking one first earth wire 21121 as an example, after electricity is applied, the current magnitude in the first earth wire 21121 and the second earth wire 21221 at the corresponding position is the same. However, since the inclination directions of the first earth wire 21121 and the second earth wire 21221 at the corresponding position are opposite, the current directions in the first earth wire 21121 and the second earth wire 21221 at the corresponding position are opposite. Furthermore, the first earth wire 21121 is subjected to opposite Ampere forces from two directions. Therefore, these opposite Ampere forces from the two directions partially cancel each other out, thereby reducing the amplitude of the up and down vibration of the first earth wire 21121 and the noise caused by the vertical vibration of the first earth wire 21121 and the second earth wire 21221.

[0226] In at least one embodiment of the present disclosure, the horizontal vibration amplitude of the first power line 21111 and the first earth line 21121 is reduced for the first sub-wiring layer 2101, the horizontal vibration amplitude of the second power line 21211 and the second earth line 21221 is reduced for the second sub-wiring layer 2102, and the vertical and horizontal vibration amplitude of the first power line 21111, the second power line 21211, the first earth line 21121, and the second earth line 21221 is reduced for the entire wiring layer 210. Therefore, compared to the related art, the noise generated when the power lines vibrate under force in a magnetic field is significantly reduced, and user satisfaction is also significantly improved.

[0227] Bonding the first sub-wiring layer 2101 and the second sub-wiring layer 2102 further includes bonding the first surface of the first sub-wiring layer 2101 to a first protective layer 3022 with a first adhesive layer 3023, bonding the second surface of the first sub-wiring layer 2101 to one side of a first insulating layer 3025 with a second adhesive layer 3024, bonding the third surface of the second sub-wiring layer 2102 to the other side of the first insulating layer 3025 with a third adhesive layer 3026, and bonding the fourth surface of the second sub-wiring layer 2102 to a second protective layer 3028 with a fourth adhesive layer 3027.

[0228] In the embodiments of the present invention, the materials of the first adhesive layer 3023, the second adhesive layer 3024, the third adhesive layer 3026, the fourth adhesive layer 3027, the first insulating layer 3025, the first protective layer 3022 and the second protective layer 3028 are outside the protective scope of the embodiments of the present invention, and therefore the materials of the first adhesive layer 3023, the second adhesive layer 3024, the third adhesive layer 3026, the fourth adhesive layer 3027, the first insulating layer 3025, the first protective layer 3022 and the second protective layer 3028 are not specifically limited.

[0229] In at least one embodiment of the present disclosure, the first insulating layer 3025 is intended to provide insulating protection between the first sub-wiring layer 2101 and the second sub-wiring layer 2102, and the first protective layer 3022 and the second protective layer 3028 are intended to provide protection to the first sub-wiring layer 2101 and the second sub-wiring layer 2102, respectively, such as preventing oxidation and damage.

[0230] In at least one embodiment of the present disclosure, a first via 2113 is provided in the first sub-wiring layer 2101, and a second via 2123 is provided in the second sub-wiring layer 2102, and the first via 2113 and the second via 2123 are intended to realize communication between the first sub-wiring layer 2101 and the second sub-wiring layer 2102.

[0231] In at least one embodiment of the present disclosure, when the wiring layer 210 not only includes the first sub-wiring layer 2101 and the second sub-wiring layer 2102 but also includes, for example, a third sub-wiring layer, one surface of the third sub-wiring layer is adhered to the second insulating layer with a fifth adhesive layer, and the other surface of the third sub-wiring layer is adhered to the second protective layer 3028 with a sixth adhesive layer, and the structure of the third sub-wiring layer is completely the same as the structure of the first sub-wiring layer 2101. By analogy therewith, any number of wiring layers 210 can be obtained. For example, the wiring layer 210 may include the first sub-wiring layer 2101, the second sub-wiring layer 2102, the third sub-wiring layer,..., the Mth sub-wiring layer, where M≧2 and M is an integer, For the Lth sub-wiring layer, if L is an even number, the wiring method of the Lth sub-wiring layer is completely the same as the wiring method of the second sub-wiring layer 2102, and if L is an odd number, the wiring method of the Lth sub-wiring layer is completely the same as the wiring method of the first sub-wiring layer 2101, where L is a positive integer and L≦M. At least one embodiment of the present disclosure can be used to adapt to various different wiring spaces, thereby further expanding the application range of the wiring structure 2.

[0232] In at least one embodiment of the present disclosure, for example, the power line and the ground line may be laid using an FPC, an FR4 hard board, or a combination of an FPC and an FR4 hard board, and for example, the power line and the ground line may be laid on the FPC by welding, a connector, or the like.

[0233] After completing the laying of the first sub-wiring layer 2101 and the second sub-wiring layer 2102 based on the above laying method, the first sub-wiring layer 2101 and the second sub-wiring layer 2102 are bonded together, then the first surface of the first sub-wiring layer 2101 is bonded to the first protective layer 3022 with a first adhesive layer 3023, the second surface of the first sub-wiring layer 2101 is bonded to one side of the first insulating layer 3025 with a second adhesive layer 3024, the third surface of the second sub-wiring layer 2102 is bonded to the other side of the first insulating layer 3025 with a third adhesive layer 3026, and the fourth surface of the second sub-wiring layer 2102 is bonded to the second protective layer 3028 with a fourth adhesive layer 3027, and further, for example, an FPC wiring structure is obtained.

[0234] In addition, in order to realize normal current flow in the obtained FPC wiring structure, at least one VCC port and at least one GND port are installed in the FPC wiring structure, and the first power line 21111 and the second power line 21211 are respectively connected to the VCC ports, and the first earth line 21121 and the second earth line 21221 are respectively connected to the GND ports.

[0235] Furthermore, in order to realize transmission of electrical signals using the FPC wiring structure, an electrical signal port and signal line 213 are further provided in the FPC wiring structure, and a first signal line 2131 is laid in another area in the first sub-wiring layer 2101 that avoids the first wiring area 2111 and the second wiring area 2112, and a second signal line 2132 is laid in another area in the second sub-wiring layer 2102 that avoids the third wiring area 2121 and the fourth wiring area 2122.

[0236] In at least one embodiment of the present disclosure, after the FPC wiring structure is energized, the current in the first signal line 2131 and the second signal line 2132 is much smaller than the current in the first power line 21111, the second power line 21211, the first earth line 21121 or the second earth line 21221, so the interference caused by the current in the first signal line 2131 and the second signal line 2132 to the first power line 21111, the second power line 21211, the first earth line 21121 or the second earth line 21221 can be ignored. For example, when the current in the first power line 21111 is 5 A, the current in the first signal line 2131 may be a relatively small current, such as 1 mA, and therefore the current in the first power line 21111 is much larger than the current in the first signal line 2131.

[0237] In the above embodiment, 1) the first power lines and one first earth line are alternately arranged in parallel, and the second power lines and one second earth line are alternately arranged in parallel, so that in the first sub-wiring layer, each first power line and one first earth line are adjacent to each other. Taking one first power line as an example, after electricity is applied, the currents in the first power line and the adjacent first earth line are the same in magnitude but opposite in direction, so that the first power line is subjected to opposing Ampere forces from two directions, and these opposing Ampere forces from the two directions partially cancel each other out, thereby reducing the horizontal vibration amplitude of the first power line and the first earth line in the first sub-wiring layer and further reducing noise caused by the horizontal vibration of the first power line and the first earth line.

[0238] 2) In the second sub-wiring layer, each second power supply line and one second earth line are adjacent to each other. Taking one second power supply line as an example, after electricity is applied, the currents in the second power supply line and the adjacent second earth line are the same in magnitude but opposite in direction, so that the second power supply line is subjected to opposite Ampere forces from two directions. Therefore, the opposite Ampere forces from the two directions partially cancel each other out, thereby reducing the horizontal vibration amplitude of the second power supply line and the second earth line in the second sub-wiring layer and further reducing the noise caused by the horizontal vibration of the second power supply line and the second earth line.

[0239] 3) Since each first power line and one second power line at a corresponding position are installed crossing each other, for example, after electricity is applied to one first power line, the currents in the first power line and the second power line at the corresponding position are the same in magnitude but opposite in direction, so the first power line is subjected to opposite Ampere forces from two directions, and therefore these opposite Ampere forces from the two directions partially cancel each other out, thereby reducing the amplitude of the up and down vibration of the first power line and further reducing the noise caused by the vertical vibration of the first power line and the second power line.

[0240] 4) Since each first earth wire and one second earth wire at a corresponding position are installed crossing each other, taking one first earth wire as an example, after electricity is applied, the currents in the first earth wire and the second earth wire at the corresponding position are the same in magnitude but opposite in direction, so the first earth wire is subjected to opposite Ampere forces from two directions, and therefore these opposite Ampere forces from the two directions partially cancel each other out, thereby reducing the amplitude of the up and down vibration of the first earth wire and further reducing the noise caused by the vertical vibration of the first earth wire and the second earth wire.

[0241] 5) The horizontal vibration amplitude of the first power line and the first earth line is reduced for the first sub-wiring layer, the horizontal vibration amplitude of the second power line and the second earth line is reduced for the second sub-wiring layer, and the vertical and horizontal vibration amplitude of the first power line, the second power line, the first earth line and the second earth line is reduced for the entire wiring layer. Therefore, compared to the related art, the noise generated when the power line vibrates due to force in the magnetic field is significantly reduced, and user satisfaction is also significantly improved.
