下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的电子设备进行详细地说明。

其中，本申请实施例的工作原理可以参见以下表述：
谐振体10依次通过连接件40、调谐件30与地板20电连接，即谐振体10可以通过连接件40和调谐件30接地，而调谐件30可以用于调节谐振体10产生的杂波的频段位于电子设备的天线的工作频段外，即可以达到将谐振 体10产生的杂波从电子设备的工作频段移除的效果，从而增强了电子设备的辐射性能。也就是说：谐振体10的产生的杂波的频段与电子设备的工作频段不会存在重合频段，这样，使得电子设备的工作频段不会受到上述谐振体10产生的杂波的干扰，从而增强了电子设备的辐射性能。
需要说明的是，本申请实施例中的电子设备的工作频段可以理解为电子设备上设置的天线的工作频段，而电子设备的辐射性能也可以理解为天线的辐射性能。

本申请实施方式中，由于电子设备内部包括的谐振体10的种类较多，可以包括同轴线、柔性电路板、具有开口的金属腔体、接地的金属连接件和加强件中的至少一种，因此，上述每一种谐振体10均可以按照上述实施方式中谐振体10的结构设置，从而可以减轻上述多种谐振体10发生的杂波对天线的工作频段的影响，进而进一步提升天线的辐射效果。
为了更清楚的说明本申请实施例，本申请实施例中均以谐振体10包括同轴线的方式来举例说明，而本申请实施例中的内容只是为了更加清楚的说明本申请实施例的方案，并不构成对本申请实施例的具体限定，且其他种类的谐振体10均可以参照本申请实施例中同轴线的结构设置，具体在此不再赘述。
其中，谐振体10包括同轴线时，同轴线可以包括壳体、传输线和金属接地层，壳体可以为绝缘壳体，传输线可以穿设于壳体内，而金属接地层可以套设于壳体的外壁上，金属接地层用于接地。而上述传输线与金属接地层之间绝缘设置，即传输线与金属接地层之间可以通过壳体实现绝缘设置，传输线中可以用于传输信号。
作为一种可选的实施方式，当所述谐振体10包括所述同轴线时，所述同 轴线与所述地板20之间部分间隔设置，所述同轴线的金属接地层依次通过所述连接件40、所述调谐件30与所述地板20电连接。这样，由于同轴线的金属接地层依次通过连接件40、调谐件30与地板20电连接，从而使得不会影响同轴线的传输线的功能的正常实现，同时，金属接地层接地，又能达到将谐振体10产生的杂波从电子设备的天线的工作频段移除的效果，从而增强了电子设备的天线的辐射性能。
当谐振体10用于连接电子设备的天线和射频单元时，传输线可以用于传输射频单元向天线发送的馈电信号。
另外，当谐振体10包括同轴线时，由于同轴线的金属接地层可以直接接地，另外，同轴线的金属接地层可以通过连接件40和调谐件30与地板20电连接，即使得同轴线的金属接地层可以通过连接件40和调谐件30进行接地，这样，不需要改变同轴线的结构，即不会改变同轴线本身的物理尺寸，也就不会影响同轴线本身功能的正常实现，从而使得同轴线的接地效果较好。
其中，地板20可以指的是电子设备的主板或者框体等部件，而地板20上可以设置有接地点。
需要说明的是，调谐件30的具体结构在此不做限定，作为一种可选的实施方式，参见图2，所述调谐件30包括电容31和电感32中的至少一项。即调谐件30可以只包括电容31或者电感32，当然，调谐件30也可以同时包括电容31和电感32，当调谐件30同时包括电容31和电感32时，电容31和电感32可以组合形成LC滤波电路，当然，电容31和电感32也可以相互并联，具体方式在此不做限定。
当调谐件30包括电感32时，且谐振体10与电感32连通时，则可以具有去载效果，从而使得谐振体10产生的杂波的频率向高频方向移动；当调谐件30包括电容31时，且谐振体10与电容31连通时，则可以具有加载效果，而使得谐振体10产生的杂波的频率向低频方向移动。
本申请实施方式中，可以根据谐振体10产生的杂波的频率选用调谐件30的种类，例如：当谐振体10产生的杂波与天线的工作频段在高频段重合时，此时，调谐件30可以选用电感32，从而使得谐振体10产生的杂波的频率向高频方向移动，进而脱离天线的工作频段，同理，当谐振体10产生的杂 波与天线的工作频段在低频段重合时，此时，调谐件30可以选用电容31，从而使得谐振体10产生的杂波的频率向低频方向移动，进而脱离天线的工作频段。这样，可以使得调谐件30的类型更加灵活化和多样化，同时，还可以增强天线的辐射性能。
另外，调谐件30除了包括电容31和电感32外，还可以包括其他元器件，其他元器件可以包括电阻33等。需要说明的是，上述电阻33的阻值在此不做限定，例如：上述电阻33的阻值可以为0欧姆，则此时第三支路相当于导线，即谐振体10可以直接接地，这样，同样可以实现将谐振体10产生的杂波的频段位于电子设备的工作频段外的目的。
作为一种可选的实施方式，参见图2，所述调谐件30包括电容31、电感32和电阻33，所述电容31位于第一支路、所述电感32位于第二支路，所述电阻33所位于第三支路，所述第一支路、所述第二支路和所述第三支路并联。
本申请实施方式中，调谐件30可以包括第一支路、第二支路和第三支路并联的电路，而电容31位于第一支路、电感32位于第二支路，电阻33所位于第三支路，这样，通过并联电容31、电感32和电阻33，从而可以进一步增强调谐件30的多样性，同时，还可以使得在调节谐振体10产生的杂波的频率时，调谐件30同时具有电容31、电感32和电阻33的调节特点，进而进一步增强对天线的辐射性能的调节效果。
需要说明的是，当调谐件30选用电容31、电感32和电阻33中的至少一种元器件时，则由于电容31、电感32和电阻33的参数已确定，此时对于谐振体10产生的杂波的频率的调节效果也已确定。而为了增强对谐振体10产生的杂波的频率的调节效果的灵活性，可以灵活的控制谐振体10与电容31、电感32和电阻33中的至少一种接通。
作为一种可选的实施方式，参见图2，所述第一支路、所述第二支路和所述第三支路中均设置有第一控制开关34，而第一支路中设置的第一控制开关34、第二支路中设置的第一控制开关34和第三支路中设置的第一控制开关34可以至少部分闭合，当然，第一支路中设置的第一控制开关34、第二支路中设置的第一控制开关34和第三支路中设置的第一控制开关34可以至少部分开启，也就是说：第一支路中设置的第一控制开关34、第二支路中设 置的第一控制开关34和第三支路中设置的第一控制开关34的状态可以灵活变化。这样，通过灵活控制第一支路、第二支路和第三支路中的第一控制开关34的状态，从而可以灵活的控制电容31、电感32和电阻33与谐振体10连通，进而可以增强对谐振体10产生的杂波的频率的调节效果的灵活性。
作为另一种可选的实施方式，所述调谐件30还包括第二控制开关，所述第二控制开关用于控制所述第一支路、所述第二支路和所述第三支路中的至少一条支路导通。这样，通过第二控制开关与第一支路、第二支路和第三支路中的至少一条支路导通，同样可以灵活的控制电容31、电感32和电阻33与谐振体10连通，进而可以增强对谐振体10产生的杂波的频率的调节效果的灵活性。
需要说明的是，在控制第一控制开关或者第二控制开关的状态时，可以根据谐振体10产生的杂波的频段来确定。
参见图1，电子设备包括第一主板101、第二主板102和金属板103，其中，第一主板101也可以被称作为主板，第二主板102也可以被称作为副板，而第一主板101上可以设置有射频单元，而第二主板102上可以设置有天线，而谐振体10可以分别连接射频单元和天线，从而实现射频单元向天线的馈电。另外，可以将谐振体10依次分为A、B、C、D和E区域，其中，A区域指的是谐振体10的一端与第一主板101扣合连接的区域，E区域指的是谐振体10的另一端与第二主板102扣合连接的区域，B区域可以被称作为谐振体10靠近第一主板101的冗余区域，D区域可以被称作为谐振体10靠近第二主板102的冗余区域，C区域可以为谐振体10嵌设于金属板103的导线槽内的区域。
需要说明的是，设置上述A区域和E区域时为了便于安装谐振体10，且上述A区域和E区域为必需的区域，因此，谐振体10无法完全与第一主板101和第二主板102贴合，即谐振体10在A区域与第一主板101存在间隙，在E区域与第二主板102存在间隙，同时，谐振体10是用于传输射频单元向天线发送的辐射信号，因此，谐振体10容易在上述A区域和E区域构成间隙天线，从而产生杂波，且杂波的频段容易落入电子设备的工作频段内，从而影响电子设备的辐射性能。
因此，为了解决上述问题，提出了本申请实施例的技术方案，具体可以参见上述实施例中的具体表述。
另外，由于A区域和E区域的电流较强，而电场较弱，而A区域和E区域之间的区域的电场较强，电流较弱，因此，为了进一步减小谐振体10对电子设备的辐射性能的影响，谐振体10可以在电场较强的位置与地板20电连接。
作为一种可选的实施方式，所述谐振体10包括第一端部、连接点和第二端部，所述连接点位于所述第一端部和所述第二端部之间，且所述连接点依次通过所述连接件40、所述调谐件30与所述地板20电连接。
其中，上述第一端部和第二端部可以分别与地板20连接，这样，由于连接点位于第一端部和第二端部之间，从而可以在电场较强的点通过连接件40和调谐件30与地板20电连接，进而进一步减小了谐振体10对电子设备的辐射性能的影响，增强了电子设备的辐射性能。
作为一种可选的实施方式，所述连接点位于所述第一端部和所述第二端部之间的中间位置。这样，由于谐振体10的中间位置的电场通常最强，则连接点位于谐振体10的中间位置(即第一端部和第二端部之间的中间位置)，则可以进一步减小了谐振体10对电子设备的辐射性能的影响，增强了电子设备的辐射性能。
作为一种可选的实施方式，参见图3，所述连接件40包括：第一接地环41和金属夹42。以同轴线为例，所述第一接地环41套设于所述同轴线的金属接地层上，且所述第一接地环41的内壁与所述金属接地层抵接，所述金属夹42与所述第一接地环41的外壁抵接，且所述金属夹42与所述调谐件30电连接。
本申请实施方式中，同轴线的金属接地层通常是网面编织金属线或者半刚性金属管，而第一接地环41套设于同轴线的外壁上，且第一接地环41的内壁与金属接地层抵接，从而可以增强与第一接地环41的内壁与金属接地层的电连接效果，同时，金属夹42与第一接地环41的外壁抵接，且金属夹42与调谐件30电连接，这样，在金属夹42的作用下，可以进一步增强第一接地环41的内壁与金属接地层的电连接效果。另外，金属夹42还可以对同轴 线起到夹持作用，以达到增强同轴线的硬度，减少同轴线由于硬度较低，导致部分与金属板103抵接，部分与金属板103存在间隙的现象的出现。
作为一种可选的实施方式，参见图3，所述金属夹42的相对两内壁上设置有第一凸起421和第二凸起422，所述第一接地环41的外壁分别与所述第一凸起421和所述第二凸起422抵接。这样，由于第一接地环41的外壁分别与第一凸起421和第二凸起422抵接，即第一接地环41可以穿设于第一凸起421和第二凸起422之间的间隙内，且第一接地环41的外壁可以分别与第一凸起421和第二凸起422抵接，从而达到将第一接地环41与金属夹42卡接的目的，进而增强了金属夹42与第一接地环41之间的电连接效果。
需要说明的是，第一凸起421和第二凸起422的形状在此不做限定，例如：第一凸起421和第二凸起422的截面可以呈矩形或者弧形。当第一凸起421和第二凸起422的截面呈弧形，可以减小第一凸起421和第二凸起422对第一接地环41的外壁造成的损伤。
作为另一种可选的实施方式，金属夹42的内壁与第一接地环41的外壁过盈配合，从而同样可以增强金属夹42与第一接地环41之间的电连接效果。
作为另一种可选的实施方式，参见图4，所述连接件40包括：第二接地环43和柔性导电连接件44，所述第二接地环43套设于所述谐振体10上，且所述第二接地环43的内壁与所述谐振体10抵接，所述柔性导电连接件44的一端与所述第二接地环43的外壁电连接，所述柔性导电连接件44的另一端与所述调谐件30电连接。
其中，上述柔性导电连接件44也可以被称作为柔性电路板，因而柔性导电连接件44的可折叠性能较好。
本实施方式中，当谐振体10所在的位置的安装空间较小(即谐振体10所在的位置的安装空间非常狭小)时，则可以在谐振体10上套设第二接地环43，并使得第二接地环43通过柔性导电连接件44与调谐件30电连接，利用柔性导电连接件44的可折叠性能较好，从而保证了谐振体10的接地效果较好。
作为一种可选的实施方式，参见图4，所述连接件40还包括：锁紧螺钉45和金属垫片46，所述锁紧螺钉45与所述柔性导电连接件44的第一表面压 合，所述柔性导电连接件44的第二表面通过所述金属垫片46与所述调谐件30电连接。这样，通过锁紧螺钉45的压合作用，可以保证柔性导电连接件44与调谐件30之间的电连接效果较好。
需要说明的是，为了进一步增强金属垫片46与柔性导电连接件44的第二表面之间的连接效果，金属垫片46朝向第二表面设置的表面上还可以设置有多个凸起，当然，金属垫片46朝向调谐件30设置的表面上也可以设置有多个凸起。
需要说明的是，图2和图4中GND用于表示接地点或者电线接地端。
另外，参见图4，连接件40还可以包括金属片47，金属垫片46和锁紧螺钉45可以均通过金属片47与调谐件30电连接，这样，可以进一步增强柔性导电连接件44与调谐件30之间的电连接效果。
需要说明的是，本申请实施例中的金属片47也可以应用于上述各个实施方式中，即可以应用于连接件40和调谐件30之间的连接方式中。
需要说明的是，上述金属片47可以为地板20上单独设置的一块区域，该金属片47不与地板20上的接地点电连接，也就是说：金属片47可以与接地点绝缘设置。
作为一种可选的实施方式，金属片47可以涂覆于地板20上的目标区域上，而目标区域可以与接地点绝缘设置，这样，使得金属片47可以与地板20上的接地点绝缘设置。另外，可选地，上述目标区域可以为绝缘区域。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
