具体实施方式
下面结合附图对本申请实施例提供的无物理滑动实体按键的移动终端进行详细描述。
如图3和图4所示，图3为本申请实施例的无物理滑动实体按键的移动终端局部结构示意图之一，图4为本申请实施例的无物理滑动实体按键的移动终端局部结构示意图之二。本申请实施例的无物理滑动实体按键的移动终端包括壳体4以及至少一个传感器5，传感器5设置在壳体4的内部，用于检测壳体4外部指定区域的按压或触碰操作；而传感器5的输出端与移动终端的主板6电连接，用于将检测信号传递给移动终端主板6。其中，传感器5可以具体采用例如压力传感器、位移传感器等接触式传感器，也可以采用电容传感器或者超声波传感器等非接触式传感器。本申请实施例的移动终端可以为手机、MP3以及平板电脑。
本实施例的无物理滑动实体按键的移动终端，通过采用非物理实体的按键来替代传统按键，从而不需要在壳体上设置和加工安装孔，简化了移动终端结构，降低了分件数量，使得移动终端组装方便，优化了手感，提高了移动终端整体强度，并且由于传感器设置于移动终端壳内，从而有效地防止了外界灰尘以及水等杂物污染按键区域。
进一步地，在传感器5为压力传感器或者位移传感器的情况下，传感器5的检测端抵接在壳体4的内壁上，通过检测壳体4的变形来检测壳体4外部指定区域的按压或触碰操作。其中，壳体4的变形状态可以通过检测产生的微小位移或者由于变形所产生的压力而获得。
在上述结构中，传感器5的检测端抵接在壳体4的内壁上,在壳体4受到外力(本实施例主要是针对手指按压壳体，并使壳体产生的局部受力)而发生变形的过程中，传感器5将壳体4的变形状况转化为与壳体4形变相关的检测信号(电压或者电流)。如图5所示，其从信号检测与控制触发的角度示出了本实施例的信号检测与控制系统的关系，为了区分真实的按键按压操作和干扰信号(例如非按键区域产生的震动信号等)，在移动终端的主板6上还可以设置有比较电路，比较电路的输入端与传感器5的输出端连接，比较电路的输出端与中央控制器连接，用于将检测信号与预设的信号阈值进行比较，如果检测信号超过信号阈值，则触发中央控制器执行按键操作，而如果没有超过信号阈值，则认为是干扰信号，可以直接被比较电路屏蔽掉。需要说明的是，这里的信号阈值可以是瞬时的信号强度，也可以是一段时间段内的平均值等，如果采用一段时间内的平均信号值可以更好地屏蔽掉瞬间触碰的误操作。这里所述说的中央控制器，可以是移动终端的CPU或者CPU与存储器外围电路模块构成的组合体等。
此外，在传感器5为电容传感器的情况下，电容传感器的电容阵列可以设置于壳体内部，通过检测所述电容单元的电容变化来检测壳体4外部指定区域的按压或触碰操作。具体地，当人体(例如手指)接近或者触碰壳体的指定区域(例如，电容阵列的正上方)，由于人体生物电会使得电容单元的电容值发生变化，从而生成检测信号。其 中，电容传感器输出的检测信号可以为电压或者电流的形式，对于检测信号的后续处理可以采用如上面提到的针对压力传感器或者位移传感器的检测信号的处理方式。
此外，在所述传感器5为超声波传感器的情况下，超声波传感器可以通过检测超声波的变化来检测壳体4外部指定区域的按压或触碰操作。当手指接近外壳的指定区域式，会产生一定的超声波，超生波传感器可以通过检测这种超生波信号来识别出用户的按键操作。其中，超声波传感器输出的检测信号可以为电压或者电流的形式，对于检测信号的后续处理可以采用如上面提到的针对压力传感器或者位移传感器的检测信号的处理方式。
为了便于用户对本申请实施例的无物理滑动实体按键的移动终端进行操作控制，在与传感器5的检测端对应的壳体4的外壁上设置有键位标识。其中，键位标识可以包括：增音量键位标识71、减音量键位标识72、静音键位标识73以及电源键位标识74。用户在使用移动终端时，直接接触的是壳体4的外壁，键位标识的设置使得用户能够精准地找到与传感器5的检测端对应的壳体4的外壁区域，从而便于用户对本申请实施例的无物理滑动实体按键的移动终端进行操作控制。
在上述键位标识中，键位标识优选地采用丝印的方式设置在壳体4的外壁上。当然，键位标识也可以采用粘贴凸凹按键的方式设置在壳体4的外壁上。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
