具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
为了便于本领域的技术人员对实施例的理解，对部分用语进行解释：
(1)VCC：Volt Current Condenser，供电电压。
(2)GND：Ground，接地。
(3)FPC：Flexible Printed Circuit,柔性印制线路板。
(4)FR4：一种耐燃材料等级的代号，是树脂材料经过燃烧状态必须能够自行熄灭的一种材料规格。
例如，当VR一体机设置绑带作为佩戴装置，且选择电池后置的结构形式，电池需要通过走线连接前面的头戴主机，以向头戴主机供电。走线要连接前后两侧的主机和电池，有两种走线形式，一种是从位于头部上方经过，另一种是从头部侧面经过。当电池线从侧面经过时，由于一般VR一体机两侧各有一个声学器件，导致走线不可避免地与声学器件紧邻。
如图1A所示，佩戴装置包括电池仓，电池仓用于存储电源，走线用于连接电源和主机。当走线部署于头戴设备的佩戴装置中时，因为主机两侧各设有一个扬声器(即，声学器件)，那么走线就不可避免的与扬声器接触。走线与扬声器相对位置的局部结构，具体参见图1B。并且，头戴设备工作过程中，扬声器中的正向磁铁会产生一个静磁场，供电导线流过的变化电流会产生变化的磁场，使得走线会在上述磁场中受力的推动而产生震动杂音，从而影响用户的使用体验。
由于声学器件和走线过近，声学器件带有磁铁，磁铁周围具有磁场，走线通电时相当于将通电导体置于磁场之中。变化的电流也会产生变化的磁场，变化的电流就会产生变化的安培力(安培力的计算方法：以电源线为电流为I、长为L的直导线为例，则在匀强磁场B中受到的安培力大小为：F＝ILBsinα，其中α为(I,B)，是电流方向与磁场方向间的夹角。而对于任意形状的电流受非匀强磁场的作用力，可把电流分解为许多段电流元IΔL，每段电流元处的磁场B可看成匀强磁场，受的安培力为ΔF＝IΔL·Bsinα，把这许多安培力矢量相加就是整个电流受的力)，因此，通电的走线在磁场中会受安培力，且变化的电流越大这个安培力就会越大，安培力推动走线震动发声，而带有磁铁的喇叭单体本身也会受安培力的反作用力，也会推动扬声器震动发声。通电导体在磁场中受到安培力作用，一旦磁场变化或者电流变化，都会使安培力大小发生变化。电池线在变化的安培力作用下，容易产生震动、发出杂音。如果扬声器固定的比较好或者本身重量比较大，则更多的震动就在走线，因此XR一体机的大部分的杂音来自于走线在通电过程中的震动。
下面参考图1C和图2-图12描述本公开一些实施例提供的头戴设备100。
本公开的实施例中，对于头戴设备100的类型不作限定，可以是任意佩戴于用户头部的设备，例如AR眼镜(AR：Augmented Reality，增强现实)、AR一体机、或者VR眼镜(VR：Virtual Reality，虚拟现实)、VR一体机、扩展现实(Extended Reality，XR)设备等。其中，XR设备可以为VR设备、增强现实(Augmented Reality，AR)设备或者混合现实(Mix reality，MR)设备等。这些设备是虚拟世界与现实世界的智能链接设备，能够看到真实世界和虚拟内容，可以进行视觉、听觉等信息的交互。
根据本发明实施例的头戴设备100，如图1C所示，包括：主机10和佩戴装置20，佩戴装置20连接主机10。通常情况下主机10戴在用户的面部，佩戴装置20和主机10之间所围空间为头戴空间。
也就是说，当头戴设备100戴在用户上，用户头部位于头戴空间内，佩戴装置20和主机10围着用户头部设置。
例如，佩戴装置20通常为两个，两个佩戴装置20位于主机10的左右两侧，这样主机10、两佩戴装置20可以连接成环，能够套住用户头部，使头戴设备100佩戴可靠。当然，本申请中也不排除头戴设备100上只设置一个佩戴装置20的方案。另外，本申请的这种头戴设备100在举例时，均以用于人体佩戴为例进行说明，但本申请也不排除头戴设备100用于动物佩戴的方案。
在本发明的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“长度”、“宽度”、“厚度”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
参照图1C，佩戴装置20内设有声学器件50和线束(也称为“走线”)40。其中佩戴装置20还包括间隔层22，间隔层22位于声学器件50和线束40之间，间隔层22为高磁导率材料层。
为便于理解本申请方案，下面参照附图所示示例，说明声学器件50与线束40的相互影响，以及设置间隔层22的原理。
如图1C所示，当声学器件50与线束40均设置在佩戴装置20内，线束40沿佩戴装置20的长度方向延伸设置，线束40的某一段位于声学器件50附近，甚至线束40的该段可能会直接贴住声学器件50。以图2和图3所示的示例为例，线束40的某一段位于声学器件50附近且二者之间间隔开。由于二者距离过近，容易产生杂音。
之所以会产生杂音，其原因在于声学器件50内通常带有磁体，该磁体周围会产生静磁场。而线束40里流通电流，根据头戴设备100使用状况的不同，电流值会发生变化。变化的电流会使线束40周围产生变化的磁场。如图3所示，声学器件50的静磁场与线束40的通电磁场相互影响，声学器件50和线束40均处于变化的磁场中。
线束40的导电部分是一种导体，通电的导体在磁场中会受力，微观上表现为洛仑兹力，宏观上表现为安培力，变化的电流就会产生变化的安培力。变化的电流越大产生的变化的安培力越大，变化的安培力会推动线束40震动发声。带有磁体的声学器件50本身也会受安培力的反作用力，反作用力会推动声学器件50震动，产生噪声。
而且由于线束40较长，很难完全固定住。有的方案中为了避免线束40两端接线处应力过大而接触不良，线束40设计时其长度留有一定冗余。甚至有的方案中，为适应不同用户佩戴需求佩戴装置20是柔性的，线束40需要随佩戴装置20可变形，因此线束40很难被完全固定住，在变化磁场中难以避免线束40震动产生的杂音。这里，导体在变化的磁场中如何产生安培力的原理及计算方法均为现有技术，这里不作具体解释。
为解决这一技术问题，本公开的方案提出在佩戴装置20上设置间隔层22，如图1C所示，间隔层22位于声学器件50和线束40之间，间隔层22为高磁导率材料层。
所谓高磁导率材料，指的是磁导率大约在100以上的磁性材料。这类材料要求磁导率高，饱和磁感应强度大，电阻高，损耗低，稳定性好等。
由于高磁导率材料层的磁导率远大于周围空气或者普通材料，因此在磁场中磁力线穿过高磁导率材料层所在的空间时，磁力线在高磁导率材料层上更加密集，从而可以降低高磁导率材料层附近区域的磁力线密度，减弱附近区域的磁场强度。例如在图4所示示例中，假设高磁导率材料层形成为方框，当处于磁场强度达H0的静磁场中，磁导率材料层通过吸引磁力线穿过，使方框中间区域的磁场强度降低至H1，从而高磁导率材料层对中间区域产生一定的磁屏蔽保护。
基于上述原因，本申请中在声学器件50和线束40之间设置了高磁导率材料层。
对于声学器件50而言，其内部磁体所产生的静磁场，是声电转化的关键部件。高磁导率材料层位于声学器件50和线束40之间，高磁导率材料层不会改变声学器件50的磁路，对其内部的磁力线密度分布影响较小。而且由于高磁导率材料层的阻隔，线束40电流变化时产生的交变磁场对声学器件50的影响减小，降低了声学器件50的震动幅度。而且由于声学器件50相对线束40，其长度较小容易固定，当声学器件50连接稳固时更加不易产生震动噪音。
对于线束40而言，由于线束40在朝向声学器件50的一侧设置了高磁导率材料层，高磁导率材料层可以大幅度减少高磁导率材料层附近的磁场强度。尤其在高磁导率材料层的阻隔后，声学器件50的静磁场对线束40影响大幅度降低。
这里还需要说明的是，传统的头戴设备上由于功能少、线束电流值小，产生的变化的安培力小，线束震动、噪音问题并不突出，人们还没有想到要如何降低线束震动噪音。
以耳机为例，有的头戴式耳机里设置有蓄电池，蓄电池通过导线连接耳机两侧的声学器件，声学器件仅具有发声功能，蓄电池向声学器件通入电流，其电压值、电流值均较低，而且声学器件内磁体的静磁场较弱。因此这种头戴式耳机里，因功能简单，声学器件和导线之间磁场影响小，导线不易震动。
随着现代技术的发展，头戴设备100的功能逐渐增加，尤其AR一体机、VR一体机中的主机10承担了虚拟现实的主要功能，主机10在某些条件下需要的电流非常大，而且声学器件50为配合虚拟现实的需要其静磁场较强，因此当线束40与声学器件50邻近安装时，容易产生磁场相互影响导致的线束40震动问题。而本申请方案的提出，正是基于头戴设备100在现代技术发展中产生问题的解决。
根据本发明实施例的头戴设备100，通过在佩戴装置20上位于声学器件50和线束40之间设置间隔层22，间隔层22为高磁导率材料层，在其高磁导率吸引下可影响线束40周围的磁力线分布，使线束40处的磁力线偏向于高磁导率材料层处，线束40处的磁通量变少，大幅度降低线束40附近的磁场强度，降低线束40受到的变 化的安培力，进而降低线束40的震动幅度，减少由线束40震动产生的杂音问题。而且声学器件50受线束40的影响降低后，声学器件50产生震动噪音的几率也会降低。
在本申请的方案中，间隔层22可以包括冷轧碳钢薄板，冷轧碳钢薄板为SPCC材料。SPCC原是“一般用冷轧碳钢薄板及钢带”钢材名称，许多国家或企业直接用来表示自己生产的同类钢材。采用冷轧碳钢薄板，其塑性及韧性较高，具有良好的焊接性能及冷冲压性，无回火脆性。可以应用于受载不大、韧性要求较高的零件中。
在本申请的方案中，间隔层22可以包括硅钢板。可以理解的是，含硅为1.0～4.5％、含碳量小于0.08％的硅合金钢叫做硅钢。间隔层22采用硅钢板，具有磁导率高、矫顽力低、电阻系数大等特性，其磁滞损失和涡流损失都较小。
在本申请的方案中，间隔层22可以包括坡莫合金板。坡莫合金指的是铁镍合金，其含镍量在35％－90％之间。间隔层22包括坡莫合金板，可以具有很高的弱磁场导磁率。而且可以有效地控制磁性能，具有很好的塑性，可以加工成超薄带及各种使用形状。
在本申请的方案中，间隔层22可以包括纳米晶板。纳米晶是指利用高能聚合球体，把水中钙、镁离子、碳酸氢根等打包产生不溶于水的纳米级晶体。采用纳米晶板作为间隔层22，具有高磁导率，频率特性宽等特点。
本申请方案中，间隔层22可以是一层也可以设置至少两层，每一层的间隔层22的实际厚度根据需要选择。
当间隔层22是一层时，间隔层22可以是冷轧碳钢薄板、硅钢板、坡莫合金板、纳米晶板中任一个。当间隔层22是多层时，间隔层22也可以选择冷轧碳钢薄板、硅钢板、坡莫合金板、纳米晶板中的一个或者多个。在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
另外，本申请中间隔层22的材料也可以不限于上述材料，还可以选择其他高磁导率的材料。
在一些实施例中，声学器件50和线束40均位于佩戴装置20内，声学器件50具有相对的出音侧和背音侧，声学器件50的出音侧朝向头戴空间设置，线束40位于声学器件50的背音侧。这里，将声学器件50和线束40均设置在佩戴装置20内，二者可以得到佩戴装置20保护，方便装配。
声学器件50的出音侧朝向头戴空间设置，使声学器件50产生的声音可以以较短路径传播至用户耳部，降低功耗。将线束40设置在声学器件50的背音侧，一方面线束40及间隔层22不会影响声音传播，另一方面在设置间隔层22后，间隔层22位于声学器件50的背音侧，对声学器件50的磁路影响较小。
具有地，在图1C的方案中，佩戴装置20具有厚度，声学器件50的厚度方向与佩戴装置20的厚度方向相一致，声学器件50的厚度较小，可以使佩戴装置20较薄。声学器件50在厚度方向上相对两侧分别为出音侧和背音侧，此时可以将线束40设置在声学器件50的背音侧，即线束40位于声学器件50的远离头戴空间的一侧。也 就是说，声学器件50与线束40在佩戴装置20内沿佩戴装置20的厚度方向排布。
还有的实施例中，声学器件50可设置在佩戴装置20表面或者声学器件50的出音侧伸出佩戴装置20，而线束40位于佩戴装置20内。或者有的实施例中，声学器件50位于佩戴装置20内，而线束40固定在佩戴装置20的表面。这里均不做限制。
当然，本申请方案不限于此，线束40也可以设置在声学器件50的上方或者下方，这样也可以将佩戴装置20设置成较扁平的形状，使头戴设备100整体较薄。
进一步地，声学器件50内设有磁体，间隔层22在声学器件50的背音侧上的垂直投影，至少覆盖磁体在声学器件50的背音侧上的垂直投影。需要说明的是，根据声学器件50内磁体的磁路特点，位于声学器件50的背音侧及出音侧其磁路线较密集。由于声学器件50在出音侧需要声音传播，因此间隔层22设置在声学器件50的背音侧，且投影可以覆盖磁体，当间隔层22面积不大时可以保证它的隔磁效果。
在本申请的方案中，间隔层22优选实体板，这样韧性、强度均足够，不易变形、移位，保证了它对线束40磁场的降低效果。
本申请方案也可以不限于此，例如间隔层22可以设置成网状，网状间隔层22可以罩住声学器件50，或者只罩在声学器件50的背音侧。
在一些实施例中，间隔层22固定连接在声学器件50上。可以理解的是，线束40较长，且线束40很难被完全固定住。将间隔层22固定在声学器件50上，使间隔层22至少与声学器件50临近的一段相对声学器件50的位置较固定。
间隔层22的设置目的在于减弱声学器件50与线束40之间的磁场影响以减少线束40的震动，相对于线束40而言声学器件50的位置较固定，当间隔层22至少与声学器件50临近的一段相对声学器件50位置固定，有助于让间隔层22保持在声学器件50和线束40之间，避免间隔层22沿线束40长度移动到其他位置。
也有的方案中，当佩戴装置20内设置有骨架，声学器件50相对骨架位置固定，此时间隔层22可以设置在骨架上。
具体地，间隔层22通过胶粘固定在声学器件50上，胶粘固定不仅固定较方便，而且省时省力，还能节省空间。
当然，本申请方案中间隔层22还可以采用其他方式固定，例如采用螺钉连接等。
如上方提到的，本申请中间隔层22可以为一层，也可以设置成至少两层。当间隔层22为至少两层时，相邻两个间隔层22可以间隔开设置，相邻两个间隔层22也可以紧贴设置。通过灵活设置间隔层22，可以根据实际产品需要，获得多样化的设置形式。
在一些具体实施例中，如图5所示，当间隔层22为至少两层时，分别为第一间隔层221和第二间隔层222，第一间隔层221的磁导率高于第二间隔层222的磁导率，第二间隔层222的磁饱和度高于第一间隔层221的磁饱和度。也就是说，间隔层22是一种组合层，在线束40和声学器件50之间设置组合层材料，可以进一步减小线束40附近的磁场强度，降低线束40震动产生的噪音。此外本申请中，限定有“第 一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。
为说明组合层的优势，这里先以单个导磁材料的磁性能进行分析。图6中示出的一种冷轧碳钢板在不同磁场强度下的磁通密度变化关系图。冷轧碳钢板在磁场强度H逐渐增加时，其磁通密度B先逐渐增加。当磁场强度达到一定值时，磁通密度B趋于不变。
为现有技术人员所公知的是，磁导率μ等于导磁材料中磁感应强度B与磁场强度H之比，即μ＝B/H。因此冷轧碳钢板在不同磁场强度下，其磁导率μ是变化的，磁导率μ的计算公式为μ＝ΔB/ΔH。冷轧碳钢板在磁场强度较低时，磁导率μ较大；当磁场强度达到一定值时，磁导率μ趋于零，冷轧碳钢板对于磁饱和状态。也就是说，当未达到磁饱和状态时，冷轧碳钢板的磁导率μ较大，当达到磁饱和时冷轧碳钢板的磁导率μ较小。
可以理解的是，一般的导磁材料对于磁导率和磁饱和度，很难两种性能都保持较高的参数。如果导磁材料的磁饱和度较高，很难保持导磁材料较高的磁导率。如果声学元件的磁体磁场特别强，仅使用磁导率过高的高磁导率材料层，可能会因磁饱和而丧失屏蔽功能。
本申请方案中，将间隔层22设置成组合层，且包括第一间隔层221和第二间隔层222，选择至少两种导磁材料进行组合，两种材料可以相互弥补不足。由于第一间隔层221的磁导率高于第二间隔层222的磁导率，第二间隔层222的磁饱和度高于第一间隔层221的磁饱和度，组合使用时通过第一间隔层221得到较高的磁导率，通过第二间隔层222得到较高的磁饱和度。这样在磁场强度较弱时能够达到良好的屏蔽功能，在磁场强度较强时也能达到良好的屏蔽功能。由此，可以进一步降低线束40震动几率，减少震动噪音。
具体地，当间隔层22包括第一间隔层221和第二间隔层222时，第一间隔层221的磁导率高于第二间隔层222的磁导率，可将第一间隔层221位于第二间隔层222的邻近声学器件50的一侧。由于距离声学器件50越近其磁力线越密集，因此在第二间隔层222降低磁场强度后，可以充分发挥第一间隔层221的磁导率高的特点。
当间隔层22数量更多时，可以进行多种形式的组合，这里不作限定。当间隔层22是组合层时，可以选择冷轧碳钢薄板、硅钢板、坡莫合金板、纳米晶板进行组合。
具体地，当间隔层22为至少两层时，相邻两个间隔层22之间胶粘相连，线束40胶粘连接在间隔层22上，间隔层22胶粘连接在声学器件50上。利用胶粘固定，可以使相邻间隔层22之间位置固定，使所有间隔层22相对声学器件50固定，使线束40在胶粘处与间隔层22相对固定。此处不仅整体结构强度较高，而且可以保持较强的屏蔽作用。
在本申请方案中，佩戴装置20可以呈带状并且戴在用户头部的左右两侧，当然本申请方案不限于此，例如有的方案中佩戴装置20是帽状且戴在用户头顶。佩戴装置20可以是软性件，这样佩戴更舒适，而且可以适应性更广。佩戴装置20也可以是 硬质件，佩戴装置20内设置容纳腔以安装线束40。
在一些可选实施例中，佩戴装置20包括安装壳和绑带，绑带与安装壳连接，声学器件50设于安装壳内，安装壳可以对声学器件50形成保护，有利于保证声学器件50的安装可靠性和稳定性，从而保证头戴设备100的使用可靠性。
如图1C所示，根据本发明的一些实施例，头戴设备100还包括电池部30，电池部30与主机10相对设置，电池部30连接佩戴装置20的后端，主机10连接在佩戴装置20的前端，电池部30、佩戴装置20和主机10所围空间为头戴空间。也就是说，当头戴设备100戴在用户上，用户头部位于头戴空间内，电池部30、佩戴装置20和主机10围着用户头部设置。
本申请的方案中，佩戴装置20通常为两个，两个佩戴装置20位于主机10的左右两侧，这样主机10、两个佩戴装置20和电池部30可以连接成环，能够套住用户头部，使头戴设备100佩戴可靠。也有一些方案中，佩戴装置20为一个，即主机10和电池部30仅单侧设置有佩戴装置20，也能稳固地戴上头戴设备100。
可选地，佩戴装置20与线束40之间填充有弹性材料。也就是说，佩戴装置20内限定出容纳腔，线束40与容纳腔的壁面之间填充有弹性材料。进一步可选地，线束40在佩戴装置20的厚度方向上的两侧分别设置弹性材料，或者，线束40的四周均通过弹性材料包裹，这样可以减小线束40的震动幅度，进而减小杂音。
另外，除与声学器件50临近的一段外，线束40其他段可以由软胶固定。软胶的选择可以有多个种类，主要的要求是粘性大、硬度小。例如，硅胶和防爆胶泥。具体地，可以通过液态硅橡胶注塑成型工艺实现，向佩戴装置20和线束40之间填充液态硅橡胶，经过冷却固化后，线束40的两侧或者整体被软胶包裹。
图7示出了本公开一些实施例提供的一种线束40的示意图；图8示出了线束40的截面图。
如图7和8所示，线束40包括信号线41、信号导线411、屏蔽层412、第一填充件413、地线42、地线导线421、第三填充件422、电源线43、电源导线431、第二填充件432、外被44。
下面参考图1C和图9-图12描述一个具体实施例中头戴设备100的结构。
如图1C所示，头戴设备100包括：主机10、佩戴装置20和电池部30，主机10用于戴在用户的面部，电池部30与主机10相对设置，戴在用户的头部后侧。佩戴装置20的前端连接主机10，电池部30连接佩戴装置20的后端。佩戴装置20内设有用于向人体耳部放声的声学器件50。电池部30具有线束40，线束40设在佩戴装置20内，且连接主机10。佩戴装置20包括间隔层22，间隔层22位于声学器件50和线束40之间，间隔层22为高磁导率材料层。
如图9所示，声学器件50包括：顶盖51、振膜52、音圈53、华司54、磁铁55、外壳56和盆架57，声学器件50装配成扁平方体件，声学器件50在顶盖51一侧为出音侧，在盆架57一侧为背音侧。这里对各部件材料不限，例如顶盖51和振膜52 为复合材料件，音圈53和外壳56为塑料件，华司54和盆架57为SPCC件。
具体地，声学器件50的静磁场中，N极位于出音侧，S极位于背音侧。图10示出了声学器件50在背音侧的结构图。当声学器件50在背音侧设置间隔层22后，其结构图如图11所示。图12示出了声学器件50在贴附的不同材料的间隔层22时的漏磁仿真效果图。
综上，本申请的这种头戴设备100，利用间隔层22的设置，可以大幅度降低线束40的震动噪音。
在本公开的一些实施例中，线束位于电源线组件中，线束包括至少一个第一导线和至少一个第二导线。图13示出了本公开一些实施例提供的另一线束400的内部结构图。
如图13所示，该线束400包括至少一个第一导线4110和至少一个第二导线4120。
之所以会产生杂音，其原因在于头戴设备100的零部件通常带有磁体，该磁体周围会产生静磁场。而线束400里流通电流，根据头戴设备100使用状况的不同，电流值会发生变化。变化的电流会使线束400周围产生变化的磁场。
线束400的导电部分是一种导体，通电的导体在磁场中会受力，微观上表现为洛仑兹力，宏观上表现为安培力，变化的电流就会产生变化的安培力。变化的电流越大产生的安培力越大，安培力会推动线束400震动发声。
而且由于线束400较长，为了避免线束400两端接线处应力过大而接触不良，通常线束400设计时其长度留有一定冗余。甚至有的方案中，为适应不同用户佩戴需求佩戴装置20是柔性的，线束400需要随佩戴装置20可变形，因此线束400很难被完全固定住，在变化磁场中难以避免线束400震动产生的杂音。这里，导体在变化的磁场中如何产生安培力的原理及计算方法均为现有技术，这里不作具体解释。
为解决这一技术问题，如图13所示，在本公开的一些实施例中，将第一导线4110与至少一个第二导线4120相邻设置，和/或，将第二导线4120与至少一个第一导线4110相邻设置。
根据本发明实施例的头戴设备100，通过将第一导线4110和至少一个第二导线4120相邻设置，将第二导线4120和至少一个第一导线4110相邻设置，可以将第一导线4110和第二导线4120所受到的相反的安培力大致抵消，从而大大减弱了线束400的受力，进而降低线束400的震动幅度，减少由线束400震动产生的杂音问题。
本申请通过将第一导线4110和至少一个第二导线4120相邻设置，将第二导线4120和至少一个第一导线4110相邻设置，可以将第一导线4110和第二导线4120所受到的相反的安培力大致抵消，从而降低线束400的震动幅度，声学器件50受线束400的影响降低后，声学器件50产生震动噪音的几率也会降低。
根据本发明的一些实施例，第一导线4110和第二导线4120中的一个为正极连接导线，第一导线4110和第二导线4120中的另一个为负极连接导线。
具体地，线束400连接电池部30和主机10，从而可以使电池部30为主机10进 行供电，第一导线4110和第二导线4120中的一个连接在电池部30的正极与主机10之间，第一导线4110和第二导线4120中的另一个连接在电池部30的负极与主机10之间。
由于第一导线4110和第二导线4120分别与电池部30的正极、负极连接，即当通电时，第一导线4110的电流方向与第二导线4120的电流方向相反，因此第一导线4110和第二导线4120会受到相反的安培力。通过将第一导线4110和至少一个第二导线4120相邻设置，将第二导线4120和至少一个第一导线4110相邻设置，可以将第一导线4110和第二导线4120所受到的相反的安培力大致抵消，从而大大减弱了线束400的受力，进而降低线束400的震动幅度，减少由线束400震动产生的杂音问题。
如图13所示，根据本发明的一些实施例，至少部分第一导线4110和至少部分第二导线4120在佩戴装置20的宽度方向上交替布置。
举例而言，第一导线4110和第二导线4120可以分别包括一个，并且第一导线4110和第二导线4120在佩戴装置20的宽度方向上交替布置；再如，第一导线4110包括一个，第二导线4120包括多个，第一导线4110与至少一个第二导线4120在佩戴装置20的宽度方向上交替布置；又如，第一导线4110包括多个，第二导线4120包括一个，第二导线4120与至少一个第一导线4110在佩戴装置20的宽度方向上交替布置。
在一些实施例中，第一导线4110和第二导线4120可以分别包括多个，在多个第一导线4110中的一部分和多个第二导线4120中的一部分中，相邻两个第一导线4110之间设有一个第二导线4120，相邻两个第二导线4120设有一个第一导线4110。
两两靠近的第一导线4110和第二导线4120的电流方向相反，根据左手法则，两者产生的安培力相反，两两靠近的第一导线4110和第二导线4120所受到的安培力大致相等且方向相反，从而可以大致抵消，由此可以大大减弱线束400的受力，进而改善杂音问题。
如图13所示，在一些实施例中，所有的第一导线4110和所有的第二导线4120在佩戴装置20的宽度方向上交替布置。
换言之，所有的第一导线4110和所有的第二导线4120呈单个线束层布置，单个线束层的厚度方向与佩戴装置20的厚度方向一致，单个线束层的宽度方向与佩戴装置20的宽度方向一致，单个线束层的长度方向与佩戴装置20的长度方向一致，既可以改善杂音问题，又可以在保证佩戴装置20尺寸不变的基础上，提高佩戴装置20的内部空间的利用率。
在一些实施例中，线束400包括多个线束层，多个线束层在佩戴装置20的厚度方向排布，每个线束层中的至少部分第一导线4110和至少部分第二导线4120在佩戴装置20的宽度方向上交替布置，进一步保证能够抵消第一导线4110和第二导线4120所受到的力，改善杂音问题。
举例而言，线束400可以包括两个线束层，这两个线束层分别包括多个第一导线4110和多个第二导线4120，并且每个线束层中的多个第一导线4110和多个第二导线4120可以在佩戴装置20的宽度方向上交替布置。当然，线束层的数量还可以为三个或者三个以上，具体可以根据导线的尺寸以及佩戴装置的尺寸进行调整。
其中，相邻两个线束层中的多个第一导线4110一一正对布置，相邻两个线束层中的多个第二导线4120一一正对布置；或者，相邻两个线束层中的多个第一导线4110在佩戴装置20的宽度方向上错开布置，相邻两个线束层中的多个第二导线4120在佩戴装置20的宽度方向上错开布置。具体地，可以根据实际情况进行调整。
当然，也可以两个线束层中的一个线束层包括一个第一导线4110，另一个线束层包括一个第二导线4120，并且，第一导线4110和第二导线4120在佩戴装置20的厚度方向排布；或者，两个线束层中的一个线束层包括一个第一导线4110，另一个线束层包括多个第二导线4120，并且多个第二导线4120可以在佩戴装置20的宽度方向上并排布置，第一导线4110和第二导线4120在佩戴装置20的厚度方向排布；或者，两个线束层中的一个线束层包括多个第一导线4110，另一个线束层包括一个第二导线4120，并且多个第一导线4110可以在佩戴装置20的宽度方向上并排布置，第一导线4110和第二导线4120在佩戴装置20的厚度方向排布。
在一些实施例中，第一导线4110的数量和第二导线4120的数量相等或者不相等。例如，第一导线4110和第二导线4120的数量均为三个或者四个；再如，第一导线4110的数量为三个且第二导线4120的数量为四个；又如，第一导线4110的数量为四个且第二导线4120的数量为三个。
如图14所示，根据本发明的另一些实施例，线束400包括第一线组4310和第二线组4320，第一线组4310和第二线组4320在佩戴装置20的厚度方向上排布。
在一些示例中，第一线组4310包括一个第一导线4110。在另一些示例中，第一线组4310包括多个第一导线4110，多个第一导线4110在佩戴装置20的宽度方向上并排布置，从而使多个第一导线4110形成第一线组4310。
在一些示例中，第二线组4320包括一个第二导线4120。在另一些示例中，第二线组4320包括多个第二导线4120，多个第二导线4120在佩戴装置20的宽度方向上并排布置，从而使多个第二导线412形成第二线组43200。
也就是说，所有的第一导线4110和所有的第二导线4120呈在佩戴装置20的厚度方向上的两排布置，第一排包括一个或者多个在佩戴装置20的宽度方向上并排布置的第一导线4110，第二排包括一个或者多个在佩戴装置20的宽度方向上并排布置的第二导线4120。
在第一线组4310包括多个第一导线4110、第二线组4320包括多个第二导线4120的实施例中，多个第一导线4110和多个第二导线4120可以在佩戴装置20的厚度方向上一一正对且相邻设置，由于两两靠近的第一导线4110和第二导线4120所受到的安培力大致相等且方向相反，因此可以大致抵消线束400所受到的力，从而减 小震动，进而改善杂音问题。
如图15所示，根据本发明的又一些实施例，第一导线4110和至少一个第二导线4120螺旋交叉布置，即第一导线4110和至少一个第二导线4120缠绕设置；和/或，第二导线4120与至少一个第一导线4110螺旋交叉布置，即第二导线4120和至少一个第一导线4110缠绕设置，不仅可以保证第一导线4110和第二导线4120布置的紧凑性，而且可以将两两靠近的第一导线4110和第二导线4120所受到的安培力抵消，改善杂音问题。
在一些实施例中，第一导线4110的数量和第二导线4120的数量相等，多个第一导线4110和多个第二导线4120一一对应地螺旋交叉布置。也就是说，多个第一导线4110和多个第二导线4120两两螺旋交叉设置，从而形成多个双绞线结构。
多个双绞线结构可以在佩戴装置20的宽度方向上并排布置，既可以改善杂音问题，又可以在保证佩戴装置20尺寸不变的基础上，提高佩戴装置20的内部空间的利用率。
需要进行说明的是，根据本发明实施例的多个第一导线4110和多个第二导线4120的排布可以根据实际空间需求进行设置，这里就不进行具体限定。
根据本发明的一些实施例，第一导线4110和/或第二导线4120的自身外部设有防护层，防护层包括橡胶层、塑料层或者碳纤维层。例如，防护层可以具体为铁氟龙或者TPE(热塑性弹性体)等，减小第一导线4110和/或第二导线4120的震动幅度，进而减小杂音。
如图16和图17所示，根据本发明的一些实施例，佩戴装置20与线束400之间填充有弹性材料60。也就是说，佩戴装置20内限定出容纳腔21，线束400与容纳腔21的壁面之间填充有弹性材料60。
在一些实施例中，线束400在佩戴装置20的厚度方向上的两侧分别设置弹性材料60，或者，线束400的四周均通过弹性材料60包裹，这样可以减小线束400的震动幅度，进而减小杂音。
在一些实施例中，线束400可以由软胶固定。软胶的选择可以有多个种类，主要的要求是粘性大、硬度小。例如，硅胶和防爆胶泥。具体地，可以通过液态硅橡胶注塑成型工艺实现，向佩戴装置20和线束400之间填充液态硅橡胶，经过冷却固化后，线束400的两侧或者整体被软胶包裹。
图18示出了本公开至少一个实施例提供的另一种头戴设备200的示意图。
如图18所示，头戴设备200包括主机110、佩戴装置120。
佩戴装置120包括扬声器(即，声学器件)130、线束150和至少一个反向磁铁140，至少一个反向磁铁140与声学器件中的正向磁铁相斥。
主机单元110与佩戴装置120相连接；佩戴装置120的内部设有扬声器130、与扬声器130中正向磁铁131相斥的至少一个反向磁铁140，以及用于向主机单元110供电的导线150。
如图19所示，佩戴装置120包括：第一佩戴子单元121和第二佩戴子单元122。
第一佩戴子单元121的一端与主机单元110的一端固定连接，第一佩戴子单元121的另一端与主机单元110的另一端固定连接，且第一佩戴子单元121的内部设置有扬声器130、与扬声器130中正向磁铁131相斥的至少一个反向磁铁140，以及用于向主机单元110供电的导线150；第二佩戴子单元122的一端与主机单元110的顶端固定连接，第二佩戴子单元122的另一端与第一佩戴子单元121的中间位置固定连接。
例如，第一佩戴子单元121为环形佩戴子单元，第二佩戴子单元122为顶部佩戴子单元，具体参见图19。由此，通过该环形佩戴子单元和顶部佩戴子单元可以更好的将主机单元110固定于用户头部。
例如，第一佩戴子单元121和第二佩戴子单元122可选为软性固定带，以通过该软性固定带可以将主机单元110较好的固定在用户的头部。
又例如，第一佩戴子单元121可选为固定连接在主机单元110两侧部分为硬性材质，其他部分可选为软性固定带。第二佩戴子单元122可选为软性固定带。由此，可以更为方便地在硬性材质中设置扬声器130、与扬声器130中正向磁铁131相斥的至少一个反向磁铁140。
又例如，第一佩戴子单元121和第二佩戴子单元122可选为硬性材质的固定单元。并且，该硬性材质的固定单元可选为弧形结构，从而形成头盔形状，使得用户基于该头盔形状的佩戴装置120能够更好的贴合佩戴者的头部。
实际使用过程中，考虑到头戴设备在工作过程中，位于佩戴装置120内部的扬声器130中的正向磁铁131会产生一个静磁场，导线150流过的变化电流会产生变化的磁场。那么该导线150会在上述磁场中受力的推动而产生震动杂音。该力在微观上为洛伦兹力，在宏观上为安培力。安培力的计算方式为：假设电流为I、导线150的长度为L。那么在匀强磁场B中受到的安培力大小为：F＝I*L*B*sinα，其中α为(I，B)表示电流方向与磁场方向间的夹角。安培力的方向由左手定则判定。对于任意形状的电流受非匀强磁场的作用力，可把电流分解为许多段电流元I*ΔL，并且每段电流元处的磁场B可看成匀强磁场，相应受到的安培力为：ΔF＝I*ΔL*B*sinα。然后，将所有安培力矢量相加即可得到整个电流受到的力。
也就是说，变化的电流会产生变化的安培力，变化的电流越大安培力就会越大，相应的导线150会受到不同安培力的推动而产生不同强度的震动杂音。
基于上述原因，本公开的一些实施例通过在佩戴装置120的内部设置与扬声器130中正向磁铁131相斥的至少一个反向磁铁140，以使头戴设备在工作过程中，利用该反向磁铁140来改变导线150周围的磁感线方向，以减小导线150周围的磁通量，使得导线150周围的磁场强度减弱，进而减少甚至消除推动导线150的安培力，从而达到减小甚至消除因导线150受到安培力的推动而产生震动杂音的目的，以改善用户的使用体验。
为了更加清楚的说明，本公开的一些实施例通过在佩戴装置120，第一佩戴子单元121的内部设置至少一个反向磁铁140，以基于该反向磁铁140改变导线150周围的磁感线方向，以减小甚至消除因导线150受到安培力的推动而产生震动杂音的技术效果。下面结合图20至图26，对第一佩戴子单元121内部设置的至少一个反向磁铁140的设置方式进行详细说明。
考虑到至少一个反向磁铁140的数量为一个或多个，因此可基于图20和图21，首先对反向磁铁数量150为一个时，在第一佩戴子单元121内部设置该反向磁铁140的设置方式进行说明。
因为扬声器130单体结构包括：防尘罩、振膜、音圈、华司、磁铁(正向磁铁)、外壳以及盆架，具体参考图9。防尘罩和振动膜为复合材料，音圈和外壳为塑料材质，以及华司和盆架为SPCC(一般用冷轧碳钢薄板及钢带)材料。
从盆架方向观看该扬声器130得到的背视图，如图26所示。由图26可知，扬声器130中正向磁铁131朝向盆架侧的磁性为S极(南极)。因此，如图20所示，本公开的一些实施例可在扬声器130的盆架外侧设置一个反向磁铁140。也就是说，该反向磁铁140朝向盆架侧的磁性也为S极。
扬声器130和导线150均设置于第一佩戴子单元121内部，那么如图21所示，若本公开的一些实施例中第一佩戴子单元121固定连接在主机单元110两侧部分的材质为硬性材质，或者第一佩戴子单元121为硬性材质的固定单元，则可选的根据扬声器130在第一佩戴子单元121中的设置位置，在第一佩戴子单元121相同位置处刻一凹槽。然后，在该凹槽内设置一个与扬声器130中正向磁铁131磁性相反的一个反向磁铁140，以利用该反向磁铁140改变导线150周围的磁感线方向。第一佩戴子单元121上的凹槽朝向扬声器130中的正向磁铁131。
考虑到扬声器130中正向磁铁131以及反向磁铁140的尺寸等因素。例如若正向磁铁131的尺寸大于一个反向磁铁140的尺寸，那么为了能够有效改变导线150周围磁感线方向，本实施例可在第一佩戴子单元121内部设置多个反向磁铁140，具体参见图22至图25。
下面结合图22至图25，对第一佩戴子单元121内部设置的多个反向磁铁140的设置方式进行具体说明。
参见图22，本公开的一些实施例可沿着第一方向，依次在扬声器130的盆架外侧设置多个反向磁铁140。
或者，参见图23，本公开的一些实施例还可沿着第二方向，依次在扬声器130的盆架外侧设置多个反向磁铁140。
第一方向可为横向或纵向，相应的第二方向可为纵向或横向。也就是说，当第一方向为横向时，第二方向为纵向；当第一方向为纵向时，第二方向为横向。纵向例如为线束的延伸方向，横向例如为垂直于线束的延伸方向的方向。
本公开的一些实施例还可在第一佩戴子单元121的凹槽内设置反向磁体140。因 此，参见图24，本公开的一些实施例可沿着第一方向，依次在第一佩戴子单元121的凹槽内设置多个所述反向磁铁140。
参见图25，本公开的一些实施例还可沿着第二方向，依次在第一佩戴子单元121的凹槽内设置多个所述反向磁铁140。
凹槽位置与第一佩戴子单元121中设置的扬声器130位置相对应，并且该凹槽朝向扬声器130中的正向磁铁131。
本公开的一些实施例中，第一方向可为横向或纵向，相应的第二方向可为纵向或横向。也就是说，当第一方向为横向时，第二方向为纵向；当第一方向为纵向时，第二方向为横向。
需要说明的是，图22至图25所示的在第一佩戴子单元121内部设置的多个反向磁铁140的数量仅为示例性的，具体数量可根据正向磁铁131的尺寸进行灵活调整，此处对其不做具体限制。
本公开的一些实施例提供的头戴设备，包括主机和佩戴装置，主机与佩戴装置相连接；佩戴装置的内部设有扬声器、与扬声器中正向磁铁相斥的至少一个反向磁铁，以及用于向主机单元供电的线束。由此，通过在佩戴装置的内部设置与扬声器中正向磁体相斥的至少一个反向磁铁，以利用该反向磁铁改变供电导线周围的磁感线方向，使得线束周围的磁场强度减弱，进而减小甚至消除推动线束运动的力，从而达到减小甚至消除因线束受到力的推动而产生震动杂音的目的，有效改善了用户的使用体验。

在本公开的至少一个实施例中，第三布线区2121设置有N条朝第二方向倾斜的第二电源线21211，第四布线区2122设置有N条朝第二方向倾斜的第二地线21221；其中，N条第二电源线21211间隔平行设置；N条第二地线21221间隔平行布设；每条第二电源线21211与一条第二地线21221按照第一排列顺序交替平行设置；N为正整数；第一方向与第二方向相反。

同理，在第二子布线层2102，实现了每条第二电源线21211与一条第二地线21221相邻；以一条第二电源线21211为例，在通电后，该条第二电源线21211与相邻第二地线21221的电流大小相同，方向相反，因此，该条第二电源线21211则受到了两个方向相反的安培力，所以，这两个方向相反的安培力彼此抵消了一部分，从而降低了第二电源线21211以及第二地线21221在第二子布线层2102的水平震动幅度；进而减小了因第二电源线21211以及第二地线21221在水平方向震动产生的噪音。
步骤S14：对所述第一子布线层2101以及第二子布线层2102进行粘合；其中，所述第一布线区2111与所述第三布线区2121交叉设置，所述第二布线区2112与第四布线区2122交叉设置。
对所述第一子布线层2101以及第二子布线层2102进行粘合，包括：将每条所述第一电源线21111与一条所述第二电源线21211呈X型交叉设置；将每条所述第一地线21121与一条所述第二地线21221呈X型交叉设置。
在本公开的至少一个的实施例中，通过将第一子布线层2101与第二子布线层2102进行粘合，可以实现将第一子布线层2101以及第二子布线层2102进行固定，进而实现将每条第一电源线21111与对应位置的第二电源线21211交叉对应。
在本公开的至少一个的实施例中，由于每条第一电源线21111与对应位置的一条第二电源线21211交叉设置，以第一电源线21111为例，在通电后，该条第一电源线21111与对应位置的第二电源线21211的电流大小相同，但是，由于该条第一电源线21111与对应位置的第二电源线21211的倾斜方向相反，因此，该条第一电源线21111与对应位置的第二电源线21211的电流方向相反；进而，该条第一电源线21111则受到了两个方向相反的安培力，所以，这两个方向相反的安培力彼此抵消了一部分，从而降低了第一电源线21111的上下震动幅度，进而减小了因第一电源线21111以及第二电源线21211在垂直方向震动产生的噪音。
同理，由于每条第一地线21121与对应位置的一条第二地线21221交叉设置，以一条第一地线21121为例，在通电后，该条第一地线21121与对应位置的第二地线21221的电流大小相同，但是，由于该条第一地线21121与对应位置的第二地线21221的倾斜方向相反，因此，该条第一地线21121与对应位置的第二地线21221的电流方向相反；进而，该条第一地线21121则受到了两个方向相反的安培力，所以，这两个方向相反的安培力彼此抵消了一部分，从而降低了第一地线21121的上下震动幅度，进而减小了因第一地线21121以及第二地线21221在垂直方向震动产生的噪音。
在本公开的至少一个的实施例中，对于第一子布线层2101，实现了降低第一电源线21111以及第一地线21121的水平震动幅度，对于第二子布线层2102，实现了降低第二电源线21211以及第二地线21221的水平震动幅度，对于整个布线层210，实现了降低第一电源线21111、第二电源线21211、第一地线21121以及第二地线21221的上下以及水平震动幅度，因此，相比相关技术，大大降低了电源线因为在磁场受力震动而产生的噪音，进而大大提高了用户的满意度。
所述对所述第一子布线层2101以及第二子布线层2102进行粘合，还包括：将所述第一子布线层2101的第一表面与第一保护层3022通过第一胶层3023粘合；将所述第一子布线层2101的第二表面与第一绝缘层3025的一侧通过第二胶层3024粘合；将所述第二子布线层2102的第三表面与所述第一绝缘层3025的另一侧通过第三胶层3026粘合；将所述第二子布线层2102的第四表面与第二保护层3028通过第四胶层3027粘合。
本发明的实施例，由于第一胶层3023、第二胶层3024、第三胶层3026、第四胶层3027、第一绝缘层3025、第一保护层3022以及第二保护层3028的材质不在本发明的实施例的保护范围内，因此，不对第一胶层3023、第二胶层3024、第三胶层3026、第四胶层3027、第一绝缘层3025、第一保护层3022以及第二保护层3028的材质做具体限定。
在本公开的至少一个的实施例中，第一绝缘层3025用于在第一子布线层2101以及第二子布线层2102之间形成绝缘保护，第一保护层3022以及第二保护层3028则用于分别对第一子布线层2101以及第二子布线层2102进行防氧化、防损害等保护。
在本公开的至少一个的实施例中，在第一子布线层2101设有第一过孔2113，在第二子布线层2102设有第二过孔2123，通过第一过孔2113以及第二过孔2123，用于实现将第一子布线层2101以及第二子布线层2102连通。
在本公开的至少一个的实施例中，当布线层210不只包括第一子布线层2101以及第二子布线层2102，例如，还包括第三子布线层，则将第三子布线层的一个表面通过第五胶层与第二绝缘层粘合；将第三子布线层的另一个表面通过第六胶层与第二保护层3028粘合；第三子布线层的结构与第一子布线层2101的结构完全相同；依次类推，可以获得包括任意层数的布线层210，例如：布线层210可以包括第一子布线层2101、第二子布线层2102、第三子布线层……第M子布线层；其中，M≥2，且M为整数；
当第L子布线层，若L为偶数，则第L子布线层的布线方式与第二子布线层2102的布线方式完全相同；若L为奇数，则第L子布线层的布线方式与第一子布线层2101的布线方式完全相同，其中，L为正整数，且L≤M。在本公开的至少一个的实施例中，用于适应各种不同的布线空间，进而可以实现扩大布线结构2的应用范围。
在本公开的至少一个的实施例中，例如，可以基于FPC、FR4硬板、或FPC与FR4硬板结合进行电源线以及地线的布设；比如，将电源线以及地线通过焊接或者连接器等方式布设在FPC上。
在基于上述布设方法完成对第一子布线层2101以及第二子布线层2102的布设以后，并对第一子布线层2101以及第二子布线层2102进行粘合；然后，将所述第一子布线层2101的第一表面与第一保护层3022通过第一胶层3023粘合；将所述第一子布线层2101的第二表面与第一绝缘层3025的一侧通过第二胶层3024粘合；将所述第二子布线层2102的第三表面与所述第一绝缘层3025的另一侧通过第三胶层3026粘合；将所述第二子布线层2102的第四表面与第二保护层3028通过第四胶层3027粘合；进而获得例如FPC布线结构。
另外，为了实现获得的FPC布线结构可以实现正常通电，FPC布线结构设置了至少一个VCC端口以及至少一个GND端口；将第一电源线21111以及第二电源线21211分别与VCC端口连接，将第一地线21121与第二地线21221分别与GND端口连接。
进一步地，为了FPC布线结构可以实现电信号的传输，FPC布线结构还设有电信号端口以及信号线213；其中，在第一子布线层2101避开第一布线区2111以及第二布线区2112的其它区域，布设有第一信号线2131；在第二子布线层2102避开第三布线区2121以及第四布线区2122的其它区域，布设有第二信号线2132。
在本公开的至少一个的实施例中，由于FPC布线结构在通电以后，第一信号线2131以及第二信号线2132中的电流相远远小于第一电源线21111、第二电源线21211、第一地线21121或第二地线21221中的电流，因此，可以忽略第一信号线2131以及第二信号线2132中的电流对第一电源线21111、第二电源线21211、第一地线21121 或第二地线21221造成的干扰；例如：当第一电源线21111中的电流为5A，第一信号线2131中的电流可能为1mA等较小的电流,因此，第一电源线21111中的电流远远大于第一信号线2131中的电流。
本上述实施例中，1)由于每条第一电源线与一条第一地线交替平行设置，每条第二电源线与一条第二地线交替平行设置，因此，在第一子布线层，实现了每条第一电源线与一条第一地线相邻，以一条第一电源线为例，因为，在通电后，该条第一电源线与相邻第一地线的电流大小相同，方向相反，所以该条第一电源线则受到了两个方向相反的安培力，这两个方向相反的安培力彼此抵消了一部分，从而降低了第一电源线以及第一地线在第一子布线层的水平震动幅度；进而减小了因第一电源线以及第一地线在水平方向震动产生的噪音。
2)在第二子布线层，实现了每条第二电源线与一条第二地线相邻；以一条第二电源线为例，因为，在通电后，该条第二电源线与相邻第二地线的电流大小相同，方向相反，因此，该条第二电源线则受到了两个方向相反的安培力，所以这两个方向相反的安培力彼此抵消了一部分，从而降低了第二电源线以及第二地线在第二子布线层的水平震动幅度；进而减小了因第二电源线以及第二地线在水平方向震动产生的噪音。
3)由于每条第一电源线与对应位置的一条第二电源线交叉设置，以一条第一电源线为例，在通电后，该条第一电源线与对应位置的第二电源线的电流大小相同，方向相反，因此，该条第一电源线则受到了两个方向相反的安培力，所以这两个方向相反的安培力彼此抵消了一部分，从而降低了第一电源线的上下震动幅度，进而减小了因第一电源线以及第二电源线在垂直方向震动产生的噪音。
4)由于每条第一地线与对应位置的一条第二地线交叉设置，以一条第一地线为例，在通电后，该条第一地线与对应位置的第二地线的电流大小相同，方向相反，因此，该条第一地线则受到了两个方向相反的安培力，所以这两个方向相反的安培力彼此抵消了一部分，从而降低了第一地线的上下震动幅度，进而减小了因第一地线以及第二地线在垂直方向震动产生的噪音。
5)对于第一子布线层，实现了降低第一电源线以及第一地线的水平震动幅度，对于第二子布线层，实现了降低第二电源线以及第二地线的水平震动幅度，对于整个布线层，实现了降低第一电源线、第二电源线、第一地线以及第二地线的上下以及水平震动幅度，因此，相比相关技术，大大降低了电源线因为在磁场受力震动而产生的噪音，进而大大提高了用户的满意度。
