在使用电子设备时，扬声器模组的低频性能对用户体验的影响至关重要，低频性能越好，音质越好，用户体验越优。而现有技术中，扬声器模组的低频性能仍然有一定的提升空间。
发明内容
本申请提供一种电子设备，能够提升电子设备的低频性能。
为达到上述目的，本申请提供了一种电子设备，该电子设备包括壳体和扬声器模组。壳体上设有出音孔。扬声器模组设置于壳体内，且扬声器模组包括壳部以及设置于壳部内的内核。壳部包括前壳和后盖，内核包括振膜，振膜与前壳围成前腔，前腔与出音孔连通。后盖位于振膜的背对前腔的一侧，且后盖设有至少一个通孔。
振膜振动时，可以驱动前腔内的空气振动，以形成声音信号由出音孔排出。同时，由于后盖设有至少一个通孔，这样，扬声器模组形成开放式后腔，可以借助壳体内的至少部分空间形成扬声器模组的至少一部分后腔，可以提升扬声器模组的低频性能。
可选的，壳体包括电池盖。电子设备还包括第一器件和第一缓冲部。第一器件设置于壳体内。第一缓冲部设置于第一器件与电池盖之间，第一器件、电池盖之间的部分第一缓冲部经由上述至少一个通孔与振膜、后盖之间的部分后腔空间连通。这样一来，借助第一器件、电池盖之间的部分第一缓冲部可以增大扬声器模组的后腔体积，从而提升扬声器模组的低频性能。
可选的，第一缓冲部可以包括空隙，也可以包括泡棉等软质弹性材料。第一缓冲部的厚度可以压缩，以允许电池盖在外力作用下向第一器件弯曲变形。
可选的，第一器件可以包括电池。
可选的，电子设备还包括第二器件，第二器件的至少部分位于第一器件与第一缓冲部之间，第一器件的朝向电池盖的表面为第一表面，第二器件在第一表面的正投影区域为第一区域，第一区域的面积小于第一表面的面积，且第一表面上位于第一区域之外的区域为第二区域。第一缓冲部包括第一弹性材料层和第二弹性材料层。第一弹性材料层的至少部分设置于第二器件与电池盖之间，第二弹性材料层的至少部分设置于第二区域与电池盖之间，第二弹性材料层在自由状态下的厚度大于第一弹性材料层在自由状态下的厚度。这样一来，通过设置厚度不同的第一弹性材料层和第二弹性材料层，并使厚度较小的第一弹性材料层的至少部分位于第二器件与电池盖之间，厚度较大的第二弹性材料层的至少部分位于第二区域与电池盖之间，可以在一定程度上提升第一缓冲部上各部分对电池盖的顶压力的均匀性，减小电池盖振动。同时，可以分 别设计第一弹性材料层和第二弹性材料层的厚度，以将第一缓冲部对电池盖的顶压力控制在合理范围内，从而可以减小设计难度，在减小电池盖振动的同时，防止电池盖与边框脱胶。
可选的，第二弹性材料层沿第一弹性材料层的周向设置。这样，第一弹性材料层与第二弹性材料层呈回字形分布，可以适配第二器件经过第一表面的中部的场景，并在该场景下，使得第一弹性材料层和第二弹性材料层在第一表面的分布均匀性较优，有利于提升第一缓冲部对电池盖的顶压力的分布均匀性。
可选的，第一弹性材料层上设有至少一个镂空孔。这样，在第一弹性材料层的材料面积一定的前提下，通过设置镂空孔可以使第一弹性材料层可以分布在第二器件上的更大范围，以提升第一弹性材料层对电池盖的顶压力的分布均匀性。

可选的，第二弹性材料层包括第三弹性材料部分和第四弹性材料部分。第三弹性材料部分为第二弹性材料层中位于第二器件与电池盖之间的部分，第四弹性材料部分为第二弹性材料层中位于第二区域与电池盖之间的部分。第三弹性材料部分在第一表面的正投影面积为第三面积，第四弹性材料部分在第一表面的正投影面积为第四面积。第三面积与第四面积之和为第二区域的面积的20％以上以及50％以下，且第三面积为第三面积与第四面积之和的40％以上以及60％以下。这样一来，第二弹性材料层的面积适中，能够在一定程度上提升第二弹性材料层对电池盖的顶压力的均匀性，同时将第二弹性材料层对电池盖的顶压力的合力控制在合理范围，防止电池盖与中框脱胶。
可选的，第二弹性材料层的厚度与第一弹性材料层的厚度的比值大于或者等于1，且小于或者等于3。这样一来，有利于减小单位面积的第二弹性材料层对电池盖的顶压力与单位面积的第一弹性材料层对电池盖的顶压力的差异，能够提升第一缓冲部对电池盖的顶压力的分布均匀性。

请参阅图1-图3，图1为本申请一些实施例提供的电子设备10在展开状态下的立体图，图2为图1所示电子设备10处于半折叠状态下的立体图，图3为图1所示电子 设备10处于折叠状态下的立体图。
电子设备10包括内屏1、外屏2和壳体3。
可以理解的是，图1-图3仅示意性的示出了电子设备10包括的一些部件，这些部件的实际形状、实际大小、实际位置和实际构造不受图1和图2的限制。在其他一些实施例中，电子设备10也可以不设置内屏1或外屏2。
另外，当电子设备10处于展开状态时，电子设备10呈矩形板状。基于此，为了方便下文各实施例的描述，针对处于展开状态下的电子设备10，建立XYZ坐标系，具体定义电子设备10的宽度方向为X轴方向，电子设备10的长度方向为Y轴方向，电子设备10的厚度方向为Z向。可以理解的是，电子设备10的坐标系设置可以根据实际需要进行灵活设置，在此不做具体限定。当然，在其他一些实施例中，处于展开状态的电子设备10也可以呈方形板状、圆形板状、椭圆形板状等等，本申请对此不做具体限定。
内屏1用于在电子设备10处于展开状态时，实现大屏显示功能。内屏1可以为柔性屏，比如，内屏1可以为有机发光二极管(organic light-emitting diode，OLED)屏幕、微型有机发光二极管(micro organic light-emitting diode)屏幕或者量子点发光二极管(quantum dot light emitting diode，QLED)屏幕。外屏2用于在电子设备10处于折叠状态时，实现小屏显示。外屏2可以为硬质屏，比如，外屏2可以为液晶屏幕(liquid crystal display，LCD)。

壳体3可以包括第一壳体31、第二壳体32以及连接于第一壳体31与第二壳体32之间的转轴机构33。当电子设备10处于展开状态时，请参阅图1，第一壳体31、转轴机构33、第二壳体32可以沿Y轴依次排列，且转轴机构33沿X轴方向延伸。这样，电子设备10为竖向折叠式折叠屏设备。在其他实施例中，当电子设备10处于展开状态时，第一壳体31、转轴机构33、第二壳体32也可以沿X轴依次排列，且转轴机构33沿Y轴方向延伸，这样，电子设备10为横向折叠式折叠屏设备。
内屏1的一部分支撑于第一壳体31，又一部分支撑于第二壳体32，再一部分支撑于转轴机构33。外屏2设置于第一壳体31的背对内屏1的一侧。
转轴机构33用于使第一壳体31与第二壳体32之间能够相对转动，以改变内屏1被第一壳体31支撑的部分和被第二壳体32支撑的部分之间在内屏1的显示侧的夹角θ，由此实现电子设备10在折叠状态与展开状态之间切换。其中，内屏1的显示侧是指内屏1的显示面所朝向的一侧，内屏1的显示面是指内屏显示视频或者图像的表面。
在一些实施例中，请参阅图1，当夹角θ大致等于180°时，内屏1以及电子设备10处于展开状态。这样可以借助内屏1实现大屏显示，以带给用户更丰富的视觉效果。当夹角θ大致等于0°时，请参阅图3，内屏1以及电子设备10处于折叠状态。这样，壳体3保护于内屏1外，避免内屏1被污染或者划伤，且电子设备10的尺寸较小，方便携带。请继续参阅图3，当电子设备10处于折叠状态时，外屏2外露，可以借助外屏2实现小屏显示。当夹角θ为0°到180°之间的角度值时，请参阅图2，电子设备10处于半折叠状态。
请参阅图4和图5a，图4为图1所示电子设备10的分解结构示意图，图5a为图4所示电子设备10内壳体3以及容置于壳体3内的电子元器件的分解结构示意图。
第一壳体31内可以设置听筒、电池、摄像头模组等电子元器件。其中，听筒也可以设置于第二壳体32或者其他位置，本申请对此不做具体限定。听筒主要应用于需要私密聆听的场景，如电话通话等。用户希望声音能够直接传入耳朵，而不被他人听到。
第二壳体32可以包括电池盖321。电池盖321用于保护第一器件4。在一些实施例中，电池盖321与第二壳体32的其他部分可以可拆卸连接，以便于打开电池盖321更换或者维修第一器件4。电池盖321的材料包括但不限于塑胶、玻璃、陶瓷和金属。
在一些实施例中，请参阅图4，第二壳体32还可以包括中框322。中框322设置于内屏1与电池盖321之间。中框322用作第二壳体32内电子元器件的支撑骨架，转轴机构33可以连接于第二壳体32的中框322与第一壳体31之间。
在一些实施例中，请参阅图5a，中框322可以包括中板3221以及设置于中板3221的边缘的边框3222。边框3222与内屏1、电池盖321围成容置空间，该容置空间用于容置中板3221以及电子设备10的一部分电子元器件。
需要说明的是，当电子设备10为其他折叠屏设备，或者为除了折叠屏设备之外的其他产品时，壳体3可以不限于图4和图5a所示结构，只要壳体3包括电池盖321即可，本申请壳体3的结构形式不做具体限定。
在一些实施例中，请参阅图5a，电子设备10还可以包括第一器件4。第一器件4可以容置于第二壳体32的容置空间。示例的，第一器件4可以包括电池。在其他示例中，第一器件4也可以为电路板或支撑件等器件，本申请是以第一器件4为电池进行示例性说明，这不能认为是对本申请构成的特殊限制。第一器件4用于向电子设备10内的电子元器件提供电量。第一器件4可以为锂离子电池、碱性电池、镍镉电池、镍氢电池或者铅酸电池等等。本申请是以第一器件4为锂离子电池进行示例性说明，锂离子电池的能量密度较高，续航时间较长。

第一器件4与电池盖321之间具有第一缓冲部g1，第一缓冲部g1的厚度可以压缩，以允许电池盖321在外力作用下向第一器件4弯曲变形。第一缓冲部g1可以包括空隙，也可以包括泡棉等软质弹性材料，图5a是以第一缓冲部g1包括软质弹性材料进行示例性说明。第一缓冲部g1用于对外力进行缓冲，减小电池盖321在外力作用下挤压并损坏第一器件4的概率。
在一些实施例中，请参阅图5b，图5b为图5a所示电子设备10中电池盖321的内表面的结构示意图，第一器件4在电池盖321的正投影为第一正投影G1，第一缓冲部g1在电池盖321上的正投影为第二正投影G2，第一正投影G1的面积小于第二正投影G2的面积，且第一正投影G1位于第二正投影G2内，这样，第一缓冲部g1覆盖整个第一器件4，可以降低电池盖321冲击第一器件4的任意部分的概率。
在一些实施例中，请参阅图5a，电子设备10还可以包括扬声器模组5。扬声器模组5也容置于第二壳体32的容置空间。扬声器模组5用于将音频电信号转换成声音信 号输出。需要说明的是，本申请实施例所述的扬声器模组5区别于听筒，用于支持音频外放的功能，应用于需要比听筒输出声音更大的场景，如语音免提、音乐播放、会议扩音、公共广播等。在这些场景中，扬声器能够将声音放大并传播到较远的距离，供多人共享，或者用户无需手持电子设备贴近耳朵，从而可以解放双手。
请参阅图6a-图6c，图6a为图5a所示电子设备10内扬声器模组5的立体图，图6b为图6a所示扬声器模组5的分解结构示意图，图6c为图6a所示扬声器模组5沿A-A向的立体剖视图。
扬声器模组5包括壳部51和内核52。壳部51用于保护内核52，并与内核52围成扬声器模组5的前腔和后腔，以实现音频电信号到声音信号的转换。
在一些实施例中，壳部51可以包括前壳511与后盖512。前壳511包括顶壁511a以及环绕顶壁511a设置的侧框511b。侧框511b上设有出声通道A，请返回参阅图4和图5a，边框3222设有出音孔B，出声通道A与出音孔B相对并连通。后盖512设置于侧框511b的背对顶壁511a的一端开口，且后盖512可以与侧框511b粘接固定。这样，壳部51由前壳511和后盖512装配形成，方便在壳部51内安装内核52。当然，在其他一些实施例中，壳部51也可以为一个结构件整体，本申请对此不做具体限定。
内核52设置于壳部51内。请参阅图7a和图7b，图7a为图6a-图6c所示扬声器模组5中内核52的立体图，图7b为图7a所示内核52沿B-B向的立体剖视图。内核52可以包括盆架521、振膜522和驱动组件523。
振膜522支撑于盆架521上。振膜522可以包括球顶522a以及连接于球顶522a与盆架521之间的振膜本体522b。球顶522a可以呈平板状，也可以呈凸球片状，本实施例是以球顶522a呈平板状进行示例性说明。振膜本体522b可以包括环绕球顶522a设置的折环522b1。折环522b1的截面形状呈弧形或近似呈弧形，且折环522b1可以向远离驱动组件523的方向拱起，也可以向靠近驱动组件523的方向拱起，图7a和图7b是以折环522b1向靠近驱动组件523的方向拱起进行示例性说明，这不能认为是对本申请构成的特殊限制。折环522b1受外力时能够发生形变，使得球顶522a能够相对于盆架521在Z轴方向上振动。驱动组件523连接于球顶522a与盆架521之间，驱动组件523用于驱动球顶522a相对于盆架521在Z轴方向上振动。
在一些实施例中，请重点参阅图7b，驱动组件523可以包括音圈523a和磁路系统523b。音圈523a设置于球顶522a上，磁路系统523b设置于盆架521上。在向音圈523a内通入交流电时，音圈523a与磁路系统523b配合，可以驱动球顶522a相对于盆架521在Z轴方向上振动。
此驱动组件523为动圈式驱动组件，结构简单，振动稳定性较高。当然，驱动组件523还可以有其他结构形式，比如可以为静电式驱动组件、电磁式驱动组件或者压电式驱动组件，本申请对此不做具体限定。
在将内核52应用于扬声器模组5内时，请结合参阅图6c和图7a，振膜522与壳部51围成前腔Q1。在一些实施例中，前腔Q1可以形成于振膜522与壳部51的前壳511之间，具体的，前腔Q1可以形成于振膜522与前壳511的顶壁511a之间。在其他实施例中，顶壁511a可以设置连通壳部51内外两侧的通孔，振膜522覆盖于通孔的连通壳部51内的一端开口，前腔Q1可以形成于通孔内，这样前腔Q1为开放式前腔。
该前腔Q1与出声通道A连通。内核52工作时，驱动组件523驱动振膜522振动，可以推动前腔内的空气振动，以形成声音信号，该声音信号由出声通道A输出，并经由出音孔B传递至用户。
振膜522的背对前腔Q1的一侧设有后腔Q2，后腔Q2可以为封闭空间，且后腔Q2可以整体位于壳部51的内部。但是，本领域技术人员知道，扬声器模组5的后腔Q2的体积在一定范围内越大，低频性能越优。而随着电子设备10向薄型化、体积小型化及功能多样化方向发展，扬声器模组5的尺寸较小，壳部51的内部空间有限，利用壳部51的内部空间形成扬声器模组5的后腔Q2，后腔Q2的体积较小，不能有效提升低频性能。
为了解决上述问题，在图6a-图6c所示的实施例中，请重点参阅图6b和图6c，壳部51上设有至少一个通孔。示例的，该至少一个通孔可以设置于后盖512上。具体的，可以在后盖512上设置开口，该开口形成通孔，也可以在后盖512上设置网状结构53，网状结构53上的网孔形成通孔，还可以在后盖512上设置海绵、泡棉等透气结构，该透气结构内的微孔形成通孔。本申请是以在后盖512上设置网状结构53，网状结构53上的网孔形成通孔进行示例性说明。网状结构可以实现空间连通，同时网状结构还可以阻止杂物进入壳部51。网状结构53的数量可以为一个，也可以为多个，本申请是以网状结构53的数量为两个进行示例性说明。通孔连通振膜522的背对前腔Q1的一侧空间与壳部51的外部空间。这样一来，扬声器模组5形成开放式后腔，在将该扬声器模组5安装于第二壳体32内时，可以借助第二壳体32内的至少部分空间形成扬声器模组5的后腔，以提升扬声器模组5的低频性能。
其中，需要说明的是，振膜522的背对前腔Q1的一侧空间是指位于振膜522的背对前腔Q1的一侧，并与振膜522邻接的一部分空间，该部分空间属于扬声器模组5的后腔Q2的至少部分。
在一些实施例中，请参阅图6c，振膜522的背对前腔Q1的一侧空间可以位于壳部51内。这样，扬声器模组5的后腔Q2包括振膜522的背对前腔Q1的一侧空间以及壳部51的外部空间，也即是，后腔Q2的一部分位于壳部51内，另一部分位于壳部51外。
在其他一些实施例中，振膜522的背对前腔Q1的一侧空间也可以位于壳部51外。也就是说，壳部51在振膜522的背对前腔Q1的一侧整体敞开形成敞开口，该敞开口形成通孔。这样，壳部51内不存在后腔空间，可以减小扬声器模组5的体积。
下文各实施例是在振膜522的背对前腔Q1的一侧空间位于壳部51内，且通孔由网状结构53上的网孔形成的基础上进行的进一步说明，这不能认为是对本申请构成的特殊限制。
在一些实施例中，网状结构53的声阻抗可以小于或者等于800rayls。示例的，网状结构53的声阻抗可以为10rayls、20rayls、30rayls、40rayls、50rayls、100rayls、150rayls、180rayls、200rayls、250rayls、300rayls、350rayls、400rayls、450rayls、500rayls、550rayls、600rayls、650rayls、700rayls、750rayls、800rayls。而且，网状结构53的有效面积可以大于或者等于3mm2。可选的，网状结构53的有效面积可以为3mm2、4mm2、5mm2、6mm2、7mm2、8mm2、9mm2 或者10mm2等等。其中，网状结构53的有效面积是指网状结构53上实际起到连通壳部51内外两部分后腔作用的部分的面积。这样，可以实现壳部51内外两部分后腔的有效连通，提升扬声器模组5的低频性能。
在一些实施例中，请参阅图8，图8为图4所示电子设备10沿C-C向的截面结构示意图。第一器件4、电池盖321之间的部分第一缓冲部g1经由后盖512上的至少一个通孔与振膜522、后盖512之间的部分后腔连通。其中，第一器件4、电池盖321之间的部分第一缓冲部g1，是指，第一缓冲部g1上在电池盖321的正投影与第一正投影G1(请参阅图5b)重合的部分，也即是第一缓冲部g1在图8所示虚线框M内的部分。振膜522的背对前腔Q1的一侧空间与该部分第一缓冲部g1连通，也就是说，该部分第一缓冲部g1处于后腔Q2内。
这样一来，借助第一器件4、电池盖321之间的部分第一缓冲部g1可以增大扬声器模组5的后腔体积，从而提升扬声器模组5的低频性能。
请返回参阅图5a，电池盖321的边缘固定于中框322，示例的，电池盖321的边缘可以借助胶层c粘接于边框3222，电池盖321上至少与第一器件4相对的部分(下文称之为第一部分)悬空设置或者近似悬空设置。同时，为了提升第一器件的续航时间，第一器件4在XY平面的尺寸较大，电池盖321上与第一器件4相对的部分的面积较大，这样电池盖321的第一部分的结构强度较低，容易产生变形。这样，在扬声器模组5工作时，振膜522容易推动后腔Q2内的空气运动，使电池盖321的第一部分相对于电池盖321的边缘产生振动。
为了解决上述问题，在第一器件4与电池盖321之间的距离一定的前提下，第一缓冲部g1可以选择采用一层厚度均匀的软质弹性材料，该软质弹性材料在自由状态下厚度大于第一器件4与电池盖321之间的安装间隙的高度，由此使得软质弹性材料保持在压缩变形状态，这样软质弹性材料对电池盖321施加一定的顶压力，该顶压力可以阻止电池盖321在扬声器模组5工作时向第一器件4产生变形。同时，在实际应用中，还需要合理设计软质弹性材料的厚度，以将软质弹性材料对电池盖321的顶压力控制在合理范围内，以避免顶压电池盖321，导致电池盖321的边缘与边框3222之间脱胶。
但是，请继续参阅图5a，电子设备10还包括第二器件F1。第二器件F1的至少部分位于第一器件4与第一缓冲部g1之间。
第二器件F1可以为电连接结构，也可以为石墨等散热结构。本申请是以第二器件F1为电连接结构进行示例性说明。第二器件F1用于电连接至少两个电子元器件。第二器件F1可以为柔性电路(flexible printed circuit，FPC)板、印制电路板(printed circuit board，PCB)或者由导线和柔性材料编织形成的结构，本申请是以第二器件F1为FPC进行示例性说明。
在一些实施例中，第一壳体31内设有第一电子元器件N1，第二壳体32内设有第二电子元器件N2。第二器件F1可以连接于第一电子元器件N1与第二电子元器件N2之间。
其中，第一电子元器件N1可以为主电路板，第二电子元器件N2可以为副电路板；或者第一电子元器件N1为副电路板，第二电子元器件N2为主电路板。本申请对此不 做具体限定。
请参阅图9a，图9a为图5a所示电子设备10中第一器件4与第二器件F1的相对位置关系示意图。为了方便下文各实施例的描述，定义第一器件4的朝向电池盖321的表面为第一表面S1，第二器件F1在第一表面S1的正投影区域为第一区域。请参阅图9b，图9b为图9a所示组件中第一区域S11在第一表面S1的相对位置示意图。第一区域S11的面积小于第一表面S1的面积，第一表面S1上位于第一区域S11之外的区域为第二区域S12。这样一来，请结合参阅图5a、图9a和图9b，在第一区域S11与电池盖321之间，第一缓冲部g1与第二器件F1产生厚度叠加；在第二区域S12与电池盖321之间，第一缓冲部g1与第二器件F1之间无交叠。若第一缓冲部g1的设置厚度较小，则对电池盖321上与第二区域S12相对的部分产生的支撑力较小，电池盖321在扬声器模组5工作时仍然会产生振动。若第一缓冲部g1的厚度设置得较大，则第一缓冲部g1与第二器件F1叠加后对电池盖321产生的顶压力较大，容易导致电池盖321与边框3222之间脱胶。因此第一缓冲部g1的设计难度较大，难以同时兼顾防止振动和防止脱胶。
为了解决上述问题，请参阅图10a-图10c，图10a为本申请一些实施例提供的电子设备10在打开电池盖321时的结构示意图，图10b为图10a所示电子设备10的分解结构示意图，图10c为图10a所示电子设备10沿D-D向的截面结构示意图。在本实施例中，第一缓冲部g1可以包括第一弹性材料层g11和第二弹性材料层g12。
第一弹性材料层g11和第二弹性材料层g12的材料可以包括软质弹性材料，可选的，第一弹性材料层g11和第二弹性材料层g12可以包括泡棉、橡胶、海绵等等。本申请是以第一弹性材料层g11和第二弹性材料层g12包括泡棉进行示例性说明，这不能认为是对本申请构成的特殊限制。
第一弹性材料层g11的至少部分设置于第二器件F1与电池盖321之间，也就是说，第一弹性材料层g11可以一部分设置于第二器件F1与电池盖321之间，也可以整体设置于第二器件F1与电池盖321之间。第二弹性材料层g12的至少部分设置于第二区域S12与电池盖321之间，也就是说，第二弹性材料层g12可以一部分设置于第二区域S12与电池盖321之间，也可以整体设置于第二区域S12与电池盖321之间。第二弹性材料层g12在自由状态下的厚度大于第一弹性材料层g11在自由状态下的厚度。其中，“自由状态”是指不受外力的状态。
这样一来，通过设置厚度不同的第一弹性材料层g11和第二弹性材料层g12，并使厚度较小的第一弹性材料层g11的至少部分位于第二器件F1与电池盖321之间，厚度较大的第二弹性材料层g12的至少部分位于第二区域S12与电池盖321之间，可以在一定程度上提升第一缓冲部g1上各部分对电池盖321的顶压力的均匀性，减小电池盖321振动。同时，可以分别设计第一弹性材料层g11和第二弹性材料层g12的厚度，以将第一缓冲部g1对电池盖321的顶压力控制在合理范围内，从而可以减小设计难度，在减小电池盖321振动的同时，防止电池盖321与边框3222脱胶。
可以理解的是，第一弹性材料层g11的形状、第二弹性材料层g12的形状以及第一弹性材料层g11与第二弹性材料层g12的相对位置关系影响了第一缓冲部g1对电池盖321的顶压力的分布均匀性。第一弹性材料层g11的形状、第二弹性材料层g12的 形状以及第一弹性材料层g11与第二弹性材料层g12的相对位置，使得第一弹性材料层g11和第二弹性材料层g12在第一表面S1的分布越均匀，则第一缓冲部g1对电池盖321的顶压力的分布均匀性越优。
在一些实施例中，请参阅图11a，图11a为图10a-图10c所示电子设备10中第一器件4、第二器件F1和第一缓冲部g1的相对位置关系图。第二弹性材料层g12沿第一弹性材料层g11的周向设置。
这样，第一弹性材料层g11与第二弹性材料层g12呈回字形分布，可以适配第二器件F1经过第一表面S1在X轴方向的中部的场景，并在该场景下，使得第一弹性材料层g11和第二弹性材料层g12在第一表面S1的分布均匀性较优，有利于提升第一缓冲部g1对电池盖321的顶压力的分布均匀性。
在一些实施例中，第二弹性材料层g12可以呈环状，比如可以呈矩形环状。第一弹性材料层g11设置于第二弹性材料层g12环绕的区域内。这样，第二弹性材料层g12的形状与第一器件4的形状匹配，第二弹性材料层g12在第一表面S1的分布均匀性较优，有利于提升第一缓冲部g1对电池盖的顶压力的分布均匀性。而且，第二弹性材料层g12为一个结构件整体，可以减小第一缓冲部g1的结构复杂度及装配难度。在其他一些实施例中，第二弹性材料层g12也可以呈圆环状、三角形环状等等，本申请对此不做具体限定。
在一些实施例中，请继续参阅图11a，第一弹性材料层g11的形状可以大致呈矩形。这样，可以增大第一弹性材料层g11在第二器件F1上的覆盖面积，以有效防止电池盖321振动。在其他一些实施例中，第一弹性材料层g11的形状也可以大致呈三角形、圆形、多边形等等，本申请对此不做具体限定。
在一些实施例中，请继续参阅图11a，第一弹性材料层g11内可以设置至少一个镂空孔h。可选的，镂空孔h的数量可以为两个，镂空孔的形状可以为矩形、方形、圆形、多边形等等，本申请是以镂空孔h的形状为矩形进行示例性说明。这样，在第一弹性材料层g11的材料面积一定的前提下，通过设置镂空孔h可以使第一弹性材料层g11可以分布在第二器件F1上的更大范围，以提升第一弹性材料层g11对电池盖321的顶压力的分布均匀性。
可以理解的是，第一弹性材料层g11的厚度与第二弹性材料层g12的厚度之间的差异也影响了第一缓冲部g1对电池盖321的顶压力的分布均匀性。
在一些实施例中，第二弹性材料层g12的厚度与第一弹性材料层g11的厚度的比值可以大于或者等于1，且小于或者等于3。可选的，该比值可以为1、1.2、1.4、1.5、1.6、1.8、2、2.2、2.4、2.6、2.8或者3。这样一来，有利于减小单位面积的第二弹性材料层g12对电池盖321的顶压力与单位面积的第一弹性材料层g11对电池盖321的顶压力的差异，能够提升第一缓冲部g1对电池盖321的顶压力的分布均匀性。
在一些实施例中，第一弹性材料层g11的厚度可以大于或者等于0.3mm，且小于或者等于0.5mm。可选的，第一弹性材料层g11的厚度可以为0.3mm、0.35mm、0.4mm、0.45mm或者0.5mm。这样，第一弹性材料层g11的厚度适中，能够在减小电池盖321振动的同时，防止电池盖321与边框3222脱胶。
在一些实施例中，第二弹性材料层g12的厚度可以大于或者等于0.5mm，且小于 或者等于1mm。可选的，第二弹性材料层g12的厚度可以为0.5mm、0.55mm、0.6mm、0.65mm、0.7mm、0.75mm、0.8mm、0.85mm、0.9mm、0.95mm或者1mm。这样，第二弹性材料层g12的厚度适中，能够在减小电池盖321振动的同时，防止电池盖321与边框3222脱胶。
可以理解的是，第一弹性材料层g11的面积和第二弹性材料层g12的面积也影响了第一缓冲部g1对电池盖321的顶压力的分布均匀性。第一弹性材料层g11的面积和第二弹性材料层g12的面积越大，顶压力的分布均匀性越优。但是在第一弹性材料层g11的厚度和第二弹性材料层g12的厚度一定的前提下，第一弹性材料层g11的面积和第二弹性材料层g12的面积越大，第一缓冲部g1对电池盖321的顶压力的合力较大，容易导致电池盖321与中框3222脱胶。
基于此，在一些实施例中，请参阅图11b，图11b为图11a所示装配结构中第二器件F1的细节结构示意图，第一弹性材料层g11可以包括第一弹性材料部分g111和第二弹性材料部分g112。第一弹性材料部分g111为第一弹性材料层g11中位于第二器件F1与电池盖之间的部分，第二弹性材料部分g112为第一弹性材料层g11中位于第二区域S12与电池盖之间的部分。
第一弹性材料部分g111在第一表面S1的正投影面积为第一面积，第二弹性材料部分g112在第一表面S1的正投影面积为第二面积。第一面积与第二面积之和为第一区域S11的面积的30％以上以及60％以下，而且，第一面积为第一面积与第二面积之和的80％以上。
这样一来，第一弹性材料层g11的面积适中，能够在一定程度上提升第一弹性材料层g11对电池盖321的顶压力的均匀性，同时将第一弹性材料层g11对电池盖321的顶压力的合力控制在合理范围，防止电池盖321与中框3222脱胶。
在又一些实施例中，请继续参阅图11b，第二弹性材料层g12可以包括第三弹性材料部分g121和第四弹性材料部分g122。第三弹性材料部分g121为第二弹性材料层g12中位于第二器件F1与电池盖之间的部分，第四弹性材料部分g122为第二弹性材料层g12中位于第二区域S12与电池盖之间的部分。
第三弹性材料部分g121在第一表面S1的正投影面积为第三面积，第四弹性材料部分g122在第一表面S1的正投影面积为第四面积。第三面积与第四面积之和为第二区域S12的面积的20％以上以及50％以下。第三面积为第三面积与第四面积之和的40％以上以及60％以下。
这样一来，第二弹性材料层g12的面积适中，能够在一定程度上提升第二弹性材料层g12对电池盖321的顶压力的均匀性，同时将第二弹性材料层g12对电池盖321的顶压力的合力控制在合理范围，防止电池盖321与中框3222脱胶。
为了防止第一弹性材料层g11和第二弹性材料层g12在整机跌落或者在受到外力作用时错位，可以固定第一弹性材料层g11和第二弹性材料层g12在电子设备10内的位置。
在一些实施例中，请返回参阅图10b，电子设备10还可以包括第一胶层k1和第二胶层k2。第一胶层k1和第二胶层k2可以为背胶，也可以为点胶。第一胶层k1设置于第一弹性材料层g11与电池盖321之间，第一弹性材料层g11借助第一胶层k1 粘接于电池盖321。第二胶层k2设置于第二弹性材料层g12与电池盖321之间，第二弹性材料层g12借助第二胶层k2粘接于电池盖321。这样，第一弹性材料层g11和第二弹性材料层g12粘接固定于电池盖321上，稳固性较优。
在一些实施例中，请继续参阅图10b，电子设备10还可以包括柔性散热片6。柔性散热片6的材料包括但不限于石墨和石墨烯。柔性散热片6的一部分设置于第二器件F1与第一缓冲部g1之间，柔性散热片6的又一部分设置于第一器件4的第二区域S12与第一缓冲部g1之间。柔性散热片6可以对第一器件4以及第二器件F1起到散热的作用，且柔性散热片6具有柔性，在第一弹性材料层g11和第二弹性材料层g12的挤压下可以产生变形，可以保证厚度不同的第一弹性材料层g11和第二弹性材料层g12对电池盖321的顶压力的分布均匀性。
在一些实施例中，柔性散热片6上各位置的厚度可以保持一致，可以减小第一弹性材料层g11和第二弹性材料层g12的厚度及面积设计难度。
请继续参阅图10b，电子设备10还包括第三器件7。第三器件7设置于第二壳体32内，并位于第一器件4的周侧。在一些实施例中，第三器件7可以为电池保护板，电池保护板与第一器件4电连接，电池保护板用于实现防止第一器件4过充、短路保护、电流保护、温度保护、电压保护、掉线保护、第一器件参数检测中的至少一种功能。当然，在其他实施例中，第三器件7也可以为电路板等其他结构，本申请是以第三器件7为电池保护板进行示例性说明。
在一些实施例中，第三器件7与电池盖321之间设有第二缓冲部g2，第二缓冲部g2的厚度也可以压缩，以允许电池盖321在外力作用下向第三器件7弯曲变形。第二缓冲部g2可以包括空隙，也可以包括泡棉等软质弹性材料。第三器件7、电池盖321之间的部分第二缓冲部g2也经由后盖512上的至少一个通孔与振膜522、后盖512之间的部分后腔连通。其中，第三器件7、电池盖321之间的部分第二缓冲部g2，是指，第二缓冲部g2上在电池盖321的正投影与第三器件7在电池盖321的正投影重合的部分。振膜522的背对前腔Q1的一侧空间与该部分第二缓冲部g2连通，也就是说，该部分第二缓冲部g2处于后腔Q2内。
这样一来，借助第三器件7、电池盖321之间的部分第二缓冲部g2，可以在一定程度上增大扬声器模组5的后腔体积，能够进一步提升扬声器模组5的低频性能。
在一些实施例中，请继续参阅图10b，第二缓冲部g2可以包括第三弹性材料层g21。第三弹性材料层g21的材料为软质弹性材料，该软质弹性材料例如可以是泡棉、硅胶、海绵等等。第三弹性材料层g21可以填充第三器件7与电池盖321之间的部分空隙，可以将后腔Q2的体积控制在一定范围内，以提升扬声器模组5的低频性能。
在一些实施例中，第三弹性材料层g21与第二弹性材料层g12可以一体成型。这样，可以减少电子设备10的组成零部件的数量，降低装配难度。
在一些实施例中，请继续参阅图10b，电子设备10还可以包括第四器件F2。第四器件F2可以为电连接结构，第四器件F2用于连接至少两个电子元器件。在一些实施例中，第二壳体32内还设有第三电子元器件N3。第三电子元器件N3位于第一器件4的背对第二电子元器件N2的一侧，第三电子元器件N3可以为闪光灯模组，第三电子元器件N3也可以为摄像头模组、振动马达等，本申请是以第三电子元器件N3为闪光 灯模组进行示例性说明。第四器件F2连接于第三电子元器件N3与第二电子元器件N2之间。
第四器件F2可以为FPC板、PCB或者由导线和柔性材料编织形成的结构，本申请是以第四器件F2为FPC进行示例性说明。当然，在其他实施例中，第四器件F2也可以为石墨片等其他结构，本申请是以第四器件F2为电连接结构进行示例性说明。
第四器件F2的至少部分设置于第三弹性材料层g21与第三器件7之间，也就是说，第四器件F2可以一部分设置于第三弹性材料层g21与第三器件7之间，也可以整体设置于第三弹性材料层g21与第三器件7之间。本实施例是以第四器件F2的一部分设置于第三弹性材料层g21与第三器件7之间进行示例性说明。
可以理解的是，第三器件7的朝向电池盖321的表面为第二表面S2，第二表面S2与第一表面S1之间在Z轴方向上存在一定的高度差，第二表面S2至电池盖321的距离大于第一表面S1至电池盖321的距离，导致第四器件F2在不悬空的前提下，第四器件F2上的承载于第一表面S1上的部分与承载于第二表面S2上的部分之间存在折弯部分，在折弯第四器件F2，以形成折弯部分的过程中，容易损坏第四器件F2。
为了解决上述问题，请继续参阅图10b，并结合参阅图12和图13，图12为图10b所示电子设备10中第一器件4、第一缓冲部g1、第二缓冲部g2、第二器件F1和第四器件F2的装配结构示意图，图13为图12所示装配结构的分解结构示意图。第二缓冲部g2还可以包括第四弹性材料层g22，第四弹性材料层g22的材料可以为软质弹性材料，该软质弹性材料例如可以是泡棉、硅胶、海绵等等。第四弹性材料层g22的至少部分设置于第四器件F2与第三器件7之间，也就是说，第四弹性材料层g22可以一部分设置于第四器件F2与第三器件7之间，也可以整体设置于第四器件F2与第三器件7之间。本实施例是以第四弹性材料层g22的一部分设置于第四器件F2与第三器件7之间进行示例性说明。
这样，借助第四弹性材料层g22可以垫高第四器件F2上与第三器件7相对的部分的高度，减小第四器件F2在第一表面S1与第二表面S2之间的连接部位的弯折量，降低第四器件F2损坏的风险。
在一些实施例中，请参阅图12和图13，第三弹性材料层g21可以包括沿第一方向Y1排列的第五弹性材料部分g211和第六弹性材料部分g212。第五弹性材料部分g211设置于电池盖321与第四器件F2之间，第六弹性材料部分g212在第三器件7上的正投影位于第四器件F2在第三器件7的正投影外。其中，第一方向Y1为第一器件4的朝向第三器件7的边缘的长度方向，可选的，第一方向Y1与Y轴方向平行。
相应的，第四弹性材料层g22可以包括沿第一方向Y1排列的第七弹性材料部分g221和第八弹性材料部分g222。第七弹性材料部分g221设置于第四器件F2与第三器件7之间，第八弹性材料部分g222设置于第六弹性材料部分g212与第三器件7之间。
这样一来，借助第三弹性材料层g21和第四弹性材料层g22可以填充第三器件7与电池盖321之间的较大空隙，可以进一步控制扬声器模组的后腔体积，提升扬声器模组的低频性能。
在一些实施例中，请继续参阅图12和图13，沿第一方向Y1，第五弹性材料部分g211与第六弹性材料部分g212可以间隔设置。这样一来，第五弹性材料部分g211与 第六弹性材料部分g212之间的空隙可以对第四器件F2进行避让。当然，在其他实施例中，第五弹性材料部分g211与第六弹性材料部分g212也可以一体成型，本申请对此不做具体限定。
在一些实施例中，请参阅图12和图13，第五弹性材料部分g211与第六弹性材料部分g212可以一体成型。这样，电子设备10包括的零部件较少，装配难度较小。当然，在其他实施例中，第五弹性材料部分g211与第六弹性材料部分g212也可以沿第一方向Y1间隔设置。
在一些实施例中，请返回参阅图10b，电子设备10还包括第三胶层k3。第三胶层k3可以为点胶，也可以为背胶。第三胶层k3设置于第三弹性材料层g21与电池盖321之间，第三弹性材料层g21借助第三胶层k3粘接于电池盖321。这样一来，可以防止第三弹性材料层g21错位。
在一些实施例中，第三胶层k3与第二胶层k2可以一体成型，以简化电子设备10的结构组成，提升电子设备10的装配效率。当然，在其他实施例中，第三胶层k3与第二胶层k2也可以分别独立设置，本申请对此不做具体限定。
在一些实施例中，请参阅图10b和图13，电子设备10还包括第四胶层k4。第四胶层k4可以为点胶，也可以为背胶。第四胶层k4设置于第四器件F2与第四弹性材料层g22之间。这样，可以避免第四弹性材料层g22错位。
在一些实施例中，请参阅图10b，电子设备10还包括第一支架8。第一支架8设置于第二壳体32的容置空间内，并与第二壳体32固定连接。可选的，第一支架8可以固定于中框322上。第一支架8与中框322之间设有贯穿孔(图中未示出)，第二器件F1的部分穿设于该贯穿孔内。第一支架8与电池盖321之间设有第五胶层k5，第五胶层k5包括点胶或者背胶。电池盖321借助第五胶层k5粘接于第一支架8上，以进一步防止电池盖321振动。
在一些实施例中，请继续参阅图10b，电子设备10还包括弹性限位结构g3，弹性限位结构g3的材料包括但不限于泡棉、海绵、橡胶或者硅胶。本申请是以弹性限位结构g3为泡棉进行示例性说明。弹性限位结构g3位于第一支架8与第一缓冲部g1之间，且弹性限位结构g3设置于第二器件F1与电池盖321之间，以限制第二器件F1的位置。
在一些实施例中，请继续参阅图10b，电子设备10还包括第六胶层k6。第六胶层k6设置于弹性限位结构g3与电池盖321之间，用于将弹性限位结构g3粘接于电池盖321上，防止弹性限位结构g3错位。
在一些实施例中，请继续参阅图10b，电子设备10还包括第三缓冲部g4，第三缓冲部g4设置于第二电子元器件N2与电池盖321之间。第三缓冲部g4的材料为软质弹性材料。示例的，第三缓冲部g4的材料可以为泡棉、海绵或者橡胶。第三缓冲部g4用于向电池盖321施加顶压力，以进一步防止电池盖321振动。
在一些实施例中，请继续参阅图10b，电子设备10还包括第七胶层k7。第七胶层k7设置于第三缓冲部g4与电池盖321之间，用于将第三缓冲部g4粘接于电池盖321上，防止第三缓冲部g4错位。
在一些实施例中，请继续参阅图10b，电子设备10还包括第二支架9，第二支架9设置于第二电子元器件N2与电池盖321之间，且第二支架9与中框322固定，以对 第二电子元器件N2起到止挡限位作用。基于此，第三缓冲部g4可以设置于第二支架9与电池盖321之间。
在一些实施例中，第一支架8位于第一器件4与转轴机构33之间，第二电子元器件N2位于第一器件4的背对第一支架8的一侧，也就是说，第二电子元器件N2与第一支架8分别位于第一器件4的相对两侧。这样一来，通过在第一支架8设置第五胶层k5，在第一器件4与电池盖之间设置第一缓冲部g1，以及在第二电子元器件N2与电池盖321之间设置第三缓冲部g4，可以提高对电池盖321的支撑均匀性，有效防止电池盖321振动。
在本说明书的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
