具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提 下所获得的所有其他实施例，都属于本发明保护的范围。
本申请中涉及的手持设备，可以是无线终端，无线终端可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(例如，RAN，Radio Access Network)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(PCS，Personal Communication Service)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(WLL，Wireless Local Loop)站、个人数字助理(PDA，Personal Digital Assistant)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)。
另外，本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
图1为本发明提供的手持设备一个实施例的结构示意图，如图1所示，包括：金属边框1、两个开关2和天线馈点3；
金属边框1的底部设置有两个断缝4，或者，金属边框1的两侧分别设置有一个断缝4；断缝4将金属边框1划分为左侧边框11、中部边框12和右侧边框13；
每个断缝4的两侧跨接有一个开关2，其中一个开关2处于导通状态，另一个开关2处于断开状态；两个开关2用于，在用户手指连通处于断开状态的开关2对应的断缝4时，两个开关2进行状态切换；
天线馈点3与中部边框12电连接，左侧边框11和右侧边框13接地，形成天线。
其中，金属边框1具体为手持设备的金属边框1。金属边框1和手持设备的背盖可以为一体成型或单独做拆件。金属边框1和背盖为一体成型时，背盖可以为金属背盖；金属边框1和背盖单独做拆件时，背盖可以为金属背盖或者非金属背盖。背盖为金属背盖时，左侧边框11与金属背盖的连接点，以及右侧边框13与金属背盖的连接点可以作为天线的地点。背盖为非金属背盖时，左侧边框11与手持设备PCB主板地的连接点，以及右侧边框13与手持设备PCB主板地的连接点可以作为天线的地点，地点可以如图2中的序号A所示，图2为本发明提供的手持设备的侧视图。
具体地，可以在每个断缝4两边分别设置传感器，通过检测用户手指是否触碰传感器来判断用户手指是否连通断缝4。若用户手指分别触碰到断缝4两边设置的传感器，则确定用户手指连通断缝4。另外，还可以实时检测天线效率，若天线效率急剧下降，则确定用户手指连通处于断开状态的开关2对应的断缝4。
两个断缝4可以设置于金属边框1的底部，或者，设置于金属边框1的两侧，如图3a和图3b所示，图3a中两个断缝4对称设置于金属边框1的底部；图3b中两个断缝4分别设置于金属边框1的两侧。
需要进行说明的是，狭义的底部可以只包括图3a中断缝4所在的位置；而广义的底部还可以包括图3a中手持设备顶部的位置，也就是说，两个断缝4还可以设置于金属边框1的顶部的位置。
进一步地，在两个断缝4设置于金属边框1的底部的情况下，开关2的类型具体可以为单刀单掷开关(single pole single throw switch，SPST)、单刀双掷开关(single pole double throw switch，SPDT)或者双刀四掷开关(DP4T)。
在第一种实施场景下，开关2的类型为单刀单掷开关。开关2的类型为单刀单掷开关时手持设备的结构示意图具体可以如图1所示，左侧开关2的输入端和输出端分别连接中部边框12和左侧边框11，右侧开关2的输入端和输出端分别连接中部边框12和右侧边框13。
在图1所示实施例的基础上，天线馈点3与中部边框12的电连接方式具体可以有两种：一种是天线馈点3与中部边框12直接连接形成天线设计，如图1所示；一种是天线馈点3与中部边框12耦合连接形成天线 设计，如图4所示，为单刀单掷开关时天线馈点3与中部边框12耦合连接的结构示意图。
另外，在第一种情形下，天线馈点3可以位于两个开关2的中间，天线馈点3到两个开关2的距离相等，即天线馈点3居中形成对称设计。在第二种情形下，天线馈点3可以位于两个开关2的中间，天线馈点3到两个开关2的距离不相等，即天线馈点3偏置形成非对称设计，如图5所示，为单刀单掷开关时天线馈点3偏置的结构示意图。
进一步地，为了保证第一个开关2断开且第二个开关2连通时电流路径激励出的天线谐振位置，与第一个开关2连通且第二个开关2断开时电流路径激励出的天线谐振位置基本一致，在开关2的类型为单刀单掷开关时，还可以在开关2的输出端串联有电感或者电容，开关2输出端串联的电感或者电容，可以微调所需谐振位置，如图6所示，为单刀单掷开关输出端串联有电感或电容时金属边框1与开关2的连接示意图。
例如，天线馈点3偏置设置时，内置天线呈非对称设计，第一个开关2断开且第二个开关2连通时电流路径激励出的天线谐振位置，与第一个开关2连通且第二个开关2断开时电流路径激励出的天线谐振位置不一致，开关2输出端串联的电感或者电容，可以微调上述谐振位置，使两个谐振位置一致，相对“死亡之握”场景下天线效率能够提高10DB左右。
而天线馈点3居中设置时，内置天线呈对称设计，第一个开关2断开且第二个开关2连通时电流路径激励出的天线谐振位置，与第一个开关2连通且第二个开关2断开时电流路径激励出的天线谐振位置基本一致，相对“死亡之握”场景下天线效率能够提高13DB以上。
在第二种实施场景下，开关2的类型为单刀双掷开关，开关2的类型为单刀双掷开关时金属边框1与开关2的连接示意图如图7所示，左侧单刀双掷开关的一个输出端串接电感或电容后，以及另一个输出端串接电感或电容后，可以连接左侧边框11；右侧单刀双掷开关的一个输出端串接电感或电容后，以及另一个输出端串接电感或电容后，可以连接中部边框12。
进一步地，还可以在单刀双掷开关的每个输出端上串接电感或电容，通过切换开关2来切换频段。
在图7所示开关类型的基础上，天线馈点3与中部边框12的电连接 方式具体可以有两种：一种是天线馈点3与中部边框12直接连接形成天线设计；一种是天线馈点3与中部边框12耦合连接形成天线设计。另外，天线馈点3可以位于两个开关2的中间，居中形成对称设计，或者偏置形成非对称设计。
在第三种实施场景下，开关2的类型为双刀四掷开关。开关2的类型为双刀四掷开关时金属边框1与开关2的连接示意图如图8所示。双刀四掷开关的一个输入端连接左侧边框11，另一个输入端连接右侧边框13；双刀四掷开关的四个输出端中，两个输出端连接中部边框12，其余两个输出端不连接，当双刀四掷开关有两种连通状态，第一种连通状态是左侧断缝4连通，右侧断缝4断开；第二种连通状态是左侧断缝4断开，右侧断缝4连通。
在图8所示开关类型的基础上，天线馈点3与中部边框12的电连接方式具体可以有两种：一种是天线馈点3与中部边框12直接连接形成天线设计；一种是天线馈点3与中部边框12耦合连接形成天线设计。另外，天线馈点3可以位于两个开关2的中间，居中形成对称设计，或者偏置形成非对称设计。
进一步地，为了保证第一种连通状态下电流路径激励出的天线谐振位置，与第二种连通状态下电流路径激励出的天线谐振位置基本一致，双刀四掷开关的输出端也可以串联电感或电容，以对天线谐振加以微调。
在上述三种开关类型对应的实施例的基础上，天线馈点3的数量还可以为两个，两个天线馈点3对称设置，通过开关2进行切换，如图9所示，图9为开关2的类型为单刀单掷开关时设置有两个天线馈点3的手持设备的结构示意图。
进一步地，在两个断缝4分别设置于金属边框1的两侧的情况下，开关2的类型，金属边框1与各类型开关2的连接方式，具体可以参见两个断缝4设置于金属边框1的底部时的说明和相关示意图。其中，在两个断缝4分别设置于金属边框1的两侧的情况下，单刀单掷开关与金属边框1的连接示意图可以如图10所示。
本实施例中，参考图11，当左侧断缝连通，右侧断缝断开时，天线馈点的馈电电流15能够通过左侧断缝到达左侧边框的接地点，天线馈点的 馈电电流14到达右侧断缝时停止，在该状态下，左侧断缝已连通，因此若用户手指连通左侧断缝，不会对天线效率产生影响，避免产生“死亡之握”；类似的，当左侧断缝断开，右侧断缝连通时，天线馈点的馈电电流能够通过左侧断缝到达左侧边框的接地点，天线馈点的馈电电流到达右侧断缝时停止，在该状态下，左侧断缝已连通，因此若用户手指连通左侧断缝，不会对天线效率产生影响，避免产生“死亡之握”，而两个开关用于，在用户手指连通处于断开状态的开关对应的断缝时，两个开关进行状态切换，从而能够使得手持设备实时有一个断缝处于断开状态，一个断缝处于连通状态，从而提高手持式通信设备的通信质量。
本实施例中，通过提供一种手持设备，包括：金属边框、两个开关和天线馈点；金属边框的底部设置有两个断缝，或者，金属边框的两侧分别设置有一个断缝；断缝将金属边框划分为左侧边框11、中部边框12和右侧边框13；每个断缝的两侧跨接有一个开关，其中一个开关处于导通状态，另一个开关处于断开状态；在用户手指连通处于断开状态的开关对应的断缝时，两个开关进行状态切换；天线馈点与中部边框12连接，形成天线，通过在用户手指连通处于断开状态的开关对应的断缝时，两个开关进行状态切换，避免“死亡之握”的产生，使得内置天线实时有一个断缝处于断开状态，提高了手持式通信设备的通信质量。
在本申请所提供的几个实施例中，应该理解到，所揭露的系统，装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述模块或单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
以上所述，以上实施例仅用以对本申请的技术方案进行了详细介绍，但以上实施例的说明只是用于帮助理解本发明的方法及其核心思想，不应理解为对本发明的限制。本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。
