(4)常规膝上型和/或掌上型接收器；
(5)常规膝上型和/或掌上型无线电电话收发器等。
参考图1和图2，在一实施例中，移动终端10为智能手机。移动终端10包括终端设备100和按键组件200，终端设备100包括显示屏110、中框120和电源模块(未图示)，显示屏110、电源模块和按键组件200分别连接于中框120，中框120能够对显示屏110、电源模块和按键组件200起到支撑和保护作用。终端设备100大致呈矩形块状，其包括相背设置的前表面111、后表面113及连接于前表面111和后表面113之间的侧表面115。显示屏110的可显示区朝向前表面111，中框120围设于可显示区且侧表面115位于中框120。显示屏110可用于显示信息并为用户提供交互界面，按键组件200用于在受到用户按压时执行相应的功能。例如，在一实施例中，用户按压按键组件200，终端设备100进入游戏模式，使得用户在玩游戏时不被来电或消息打扰。在其他实施方式中，用户按压按键组件200，终端设备100可以进入静音模式或者其他模式等。在一实施例中，电源模块包括能够反复充放电的锂电池，电源模块能够为显示屏110和移动终端10内部的其他电子元器件供电。在其他实施方式中，电源模块可以包括其他新型电池例如燃料电池、核电池或石墨烯电池等。在其他实施方式中，移动终端10还可以为平板、掌 上电脑等。
参考图3和图4，按键组件200包括柔性线路板(FPC，Flexible Printed Circuit)210、第一压力传感器220、指示灯230和导光件240。柔性线路板210用于连接至终端设备100，以使终端设备100的电源模块能够通过柔性线路板210为指示灯230供电。第一压力传感器220连接于柔性线路板210，中框120在受到按压时能够将压力传导至第一压力传感器220。第一压力传感器220感应压力后能够将触发信号传输至终端设备100，终端设备100即可执行相应的功能。指示灯230连接于柔性线路板210，导光件240与中框120连接，导光件240的外露于中框120的表面与中框120的侧表面115平齐。当指示灯230点亮时，指示灯230发出的光线能够照射至导光件240，以使导光件240发光。
具体地，在一实施例中，导光件240包括基材和印制在基材上的导光点，基材为光学级材料，导光点为具有极高反射率且不吸光的材料。通过激光雕刻、V型十字网格雕刻、UV网版印刷技术等方式可以在基材印上导光点。从指示灯230发出的光可以被基材吸收，当光线射到各个导光点时，反射光会往各个角度扩散，最终由导光件240射出。通过设置疏密、大小不一的多个导光点，可使导光件240均匀发光。在其他实施方式中，导光件240也可以为导光硅胶等材质。柔性线路板210的末端设有板对板(BTB，Board-to-Board)连接器的公头，终端设备100包括主板，主板设有板对板连接器的母座，公头和母座能够配合连接，以使按键组件200连接于主板进而实现按键组件200与终端设备100的通信连接。板对板连接器的结构有利于公头和母座的标准化，并有利于按键组件200与终端设备100的通信连接。终端设备100可以控制指示灯230的通断，以使指示灯230点亮或者熄灭。
在一实施例中，指示灯230为LED灯，LED灯的耗电量低，有利于降低按键组件200的能耗，以延长终端设备100的续航时间。由于指示灯230可以贴合连接于柔性线路板210，使得指示灯230的布局较为紧凑，且无需增加额外的柔性线路板210来点亮指示灯230，因而可以提升移动终端10内部 空间的利用率。在一实施例中，指示灯230发出彩色的光，例如，指示灯230点亮时能够发出红光，或者绿光，或者蓝光等，以使导光件240透出的光具有较好的装饰效果。
参考图4，在一实施例中，导光件240包括一体成型的主体部241和限位部243，限位部243朝向指示灯230，中框120开设有安装孔，主体部241和限位部243穿设于安装孔，且主体部241外露于中框120，用户可以接触主体部241外露于中框120的部分。主体部241的远离限位部243的表面与中框120的侧表面115平齐。在终端设备100的厚度方向上，限位部243的尺寸大于主体部241的尺寸以使导光件240的横断面大致呈T形。在终端设备100的宽度方向上，上述结构使得导光件240不能轻易从安装孔内脱出。进一步，主体部241的外露于中框120的表面呈长形，例如，主体部241的外露于中框120的表面可以为矩形、圆角矩形或者跑道形等形状。上述结构有利于增大导光件240的发光长度，以使用户能够方便地识别、定位至按键组件200。
上述移动终端10及其按键组件200，按键组件200的导光件240与中框120的侧表面115平齐，移动终端10具有较高的外观整体性。且上述按键组件200的设置，无需在中框120的侧表面115设置凹槽或凸起以定位按键组件200，从而可以简化中框120的加工步骤。由于指示灯230点亮时能够使得导光件240发光，指示灯230和导光件240的设置有利于用户定位至按键组件200，以准确地将按压作用力传递至第一压力传感器220。例如，在光线不足的环境中，指示灯230点亮使得导光件240发光，用户可以准确地按压导光件240所在位置处的中框120使得中框120发生形变，进而将按压的压力传导至第一压力传感器220。在一实施例中，终端设备100包括环境光传感器和处理器，环境光传感器用于检测环境光线的强度，当环境光强度较低时，处理器可以控制指示灯230点亮，以使导光件240点亮。可以理解的是，处理器也可以控制指示灯230处于常亮状态，或者通过识别使用场景以点亮指示灯230。
参考图4，在一实施例中，按键组件200包括位于第一压力传感器220和中框120之间的连接件250，连接件250用于将第一压力传感器220固定连接于中框120。在一实施例中，连接件250为双面胶，其厚度较薄且能够将压力传感器可靠地连接于中框120。在其他实施方式中，连接件250可以为热熔胶等。
进一步，按键组件200可以包括连接于柔性线路板210上的加强件260，加强件260和第一压力传感器220分别位于柔性线路板210的两个相背设置的表面。具体地，加强件260包括钢片，钢片与第一压力传感器220平行设置。钢片可以采用冲压成型制成，钢片的厚度较薄且结构强度较高，其能够支撑柔性线路板210，在第一压力传感器220挤压柔性线路板210变形时，钢片能够产生变形，在压力解除后钢片能够带动柔性线路板210回复原状。
进一步，按键组件200可以包括第二压力传感器270，第二压力传感器270连接于加强件260的背向第一压力传感器220的一侧，且第二压力传感器270与柔性线路板210连接。第二压力传感器270用于感应按压的压力，并将触发信号传输至终端设备100，以使终端设备100执行相应的功能。第二压力传感器270可以校正第一压力传感器220的按压信号，以防止第一压力传感器220在误触的情况下，终端设备100执行相应的功能。例如，在终端设备100意外跌落时，第一压力传感器220感应压力信号的时间较短，第二压力传感器270感应压力的时间更短，因此可以设定程序，判定该种情况下，终端设备100不执行按键组件200触发的功能。
进一步，参考图4，柔性线路板210的靠近中框120的端部为U形结构211，且加强件260和第二压力传感器270容置于U形结构211内。第一压力传感器220位于U形结构211外，且指示灯230与第一压力传感器220位于U形结构211的同一侧。上述结构的柔性线路板210，一方面利用U形结构211可以对加强件260和第二压力传感器270予以保护，另一方面U形结构211使得柔性线路板210的部分结构叠设于第一压力传感器220、第二压力传感器270和加强件260上，进而可以节省第二压力传感器270和加强件260 在终端设备100的宽度方向上占用的尺寸，以使移动终端10的内部结构更为紧凑。
参考图5，图5为本申请实施例提供的终端设备100的结构示意图。该终端设备100可以包括射频(RF，Radio Frequency)电路501、包括有一个或一个以上计算机可读存储介质的存储器502、输入单元503、显示单元504、传感器505、音频电路506、无线保真(WiFi，Wireless Fidelity)模块507、包括有一个或者一个以上处理核心的处理器508、以及电源509等部件。本领域技术人员可以理解，图5中示出的终端设备100结构并不构成对终端设备100的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
