具体实施方式
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，所描述的实施例仅仅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。
为了解决现有技术中用户设备上的话筒被堵的问题。本发明实施例提供 一种用户设备，其中该用户设备应用于当用户通过用户设备在通话时，手指、脸部等遮挡话筒时的场景，该用户设备可以是手机、平板电脑等，该用户设备包括电容检测装置、控制单元、话筒和提示装置，其中电容检测装置包括触控单元和电容检测单元，其中电容检测单元的两端分别与触控单元和控制单元电性连接，图1为本发明实施例一提供的电容检测装置与话筒配合使用的示意图，如图1所示，触控单元101上开设有开孔102，所述开孔102与所述话筒103的送音孔对齐，即触控单元101与话筒103对应，触控单元101通过第一连接器104实现与电容检测单元105的电性连接。
下面介绍电容检测装置的具体结构：
图2为本发明实施例一提供的电容检测装置的结构示意图，该电容检测装置包括触控单元101和电容检测单元105，结合图1和图2所示，电容检测装置检测话筒被遮挡的过程为：当手指触摸到触控单元101后，触控单元101感测到它所在的触摸区域的电容变化，这时电容检测单元105根据触控单元101感测到的电容变化测量触摸区域的电容值，并将测量的电容值发送给控制单元，控制单元判断电容值大于或者等于第一预设值，则确定有物体触摸到触控单元，由于话筒103是位于触摸区域的，因此表示有物体遮挡了话筒103，则控制单元控制提示装置发送提示信息。进一步地，如图2所示，触控单元101通过第一连接器104实现与电容检测单元105的电性连接，具体连接方式可以为：第一连接器104的一端通过连接线106与触控单元101连接，第一连接器104的另一端与用户设备的主板上的第二连接器电性连接，触控单元101上开设有开孔102，其中触控单元101、连接线106和第一连接器104铺设在柔性电路板上；电容检测单元105与第二连接器电性连接。为减少其他连接线产生的寄生电容，电容检测单元105和柔性电路板应尽量靠近，进一步地，由于矩形的尖角会集中磁场，形成干扰源，因此本发明实施例提供的触控单元101的形状是圆角矩形，通过连接线106连接到柔性电路板上的第一连接器104，并在四周利用网格地进行包地处理，柔性电路板背面粘贴双面胶，安装时可以贴在手机后壳的内侧，位于手机话筒胶套与手机后壳之间，这样不影响外观，抗静电释放(Electro-Static discharge，简称ESD)能力好，同时由于柔性电路板可以根据需要产生形变，因此，这样可以实现触控单元101与话筒的对应。
可选地，所述提示装置包括所述用户设备上的扬声器、振动器或者显示器中的至少一者，因此对应的提示信息可以为语音提示、振动提示或者文字提示等。比如语音信息可以是：“话筒被堵，请注意”等。容易理解的是，这里的控制单元可以是中央处理器(Central Processing Unit，简称CPU)。
其中本发明实施例中的触控单元可以是金属材料制作成的金属线圈，比如它可以是铜线圈。只要能够连接两个有源器件，用于传输电流或信号的连接器都可以作为第一连接器和第二连接器，当然，其他能产生电容变化的部件也可以，比如触控板等等。此外，电容检测单元可以是芯片。
本发明实施例提供一种用户设备，包括电容检测装置、控制单元、话筒和提示装置；电容检测装置包括：触控单元和电容检测单元；触控单元，用于感测触控单元所在的触摸区域的电容变化，话筒位于触摸区域内；电容检测单元与触控单元电性连接，电容检测单元根据触控单元感测到的电容变化测量触摸区域的电容值，并向控制单元发送电容值；控制单元判断电容值是否大于或者等于第一预设值，若是，则确定话筒被遮挡住，并控制提示装置发送提示信息，从而彻底的解决了话筒被堵的问题，进而提高用户通话的顺畅性。
图3为本发明实施例二提供的电容感应原理框图，图3中的芯片型号为：CY8CMBR3108，这里的芯片可以作为图1和图2中所述的电容检测单元，如图3所示，CS0、CS1和CS2表示触控单元，它们分别通过引脚CS0/PS0、CS1/PS1和CS2/PS2与CY8CMBR3108芯片电性连接，其中，I2C_SCL、I2C_SDA为和控制单元通信的I2C信号，TO_HOST为和控制单元通信的中断信号。当手指接触到触控单元CS0、CS1或者CS2时，CY8CMBR3108会测量电容值，当发现电容值增大，则通过中断信号TO_HOST通知控制单元，并通过集成电路总线(Inter-Integrated Circuit，简称IIC)和控制单元交互信息，比如将测量到的电容值发送给控制单元。控制单元判断电容值是否大于第一预设值，若是，则控制单元控制提示装置向用户发送提示信息。
基于上述的电容感应原理，本发明实施例还提供一种电容检测装置，具体如下：
图4为本发明实施例三提供的电容检测装置的结构示意图，如图4所示，其中所述电容检测装置包括：触控单元和电容检测单元400，其中触控单元 包括：第一触控部分401和第二触控部分402，第一触控部分401和所述第二触控部分402相对设置形成一个开孔403，所述开孔403与所述话筒的送音孔对应，进一步地，该电容检测单元400可以为触摸屏芯片，触摸屏芯片的一个发送端与第一触控部分电性连接，所述触摸屏芯片的一个接收端与所述第二触控部分电性连接，该电容检测装置与话筒的配合实用类似于图1所示，第一触控部分401和第二触控部分402用于感测触摸区域的电容变化；第一连接器404的一端通过两条连接线405分别与第一触控部分401和所述第二触控部分402连接，第一连接器404的另一端与所述用户设备的主板上的第二连接器电性连接，其中第一触控部分401、第二触控部分402、第一连接器404和两条所述连接线405铺设在柔性电路板上。电容检测单元400与第二连接器电性连接，电容检测单元400，即触摸屏芯片中包括至少一个发送端(Transmit，简称TX)和至少一个接收端(Receive，简称RX)，其中所述发送端TX与所述第一触控部分401依次通过所述第二连接器、第一连接器404和一条连接线405连接，所述接收端RX与所述第二触控部分402依次通过所述第二连接器、所述第一连接器404和一条所述连接线405连接，并且这两个发送端和接收端独立于触摸屏芯片中的其他发送端和接收端。
其中本发明实施例中的第一触控部分和第二触控部分可以是由金属丝制程，它们分别可以做成半圆形，以使它们之间形成一个开孔。同理，也可以是其他可以产生电容变化的部件。只要能够连接两个有源器件，用于传输电流或信号的连接器都可以作为第一连接器和第二连接器。连接线可以是铜线。
本发明实施例提供一种电容检测装置，其中第一触控部分、第二触控部分和电容检测单元，第一触控单元和第二触控单元之间存在开孔，所述开孔与话筒的送音孔对齐，一旦有物体堵住送音孔，那么电容检测单元就会检测到话筒所在位置电容增大，这时触摸屏芯片将测量到的电容值发送给控制单元，控制单元根据该电容值判断话筒是否被堵住，若是，控制单元控制提示装置提示用户话筒被堵住，从而彻底的解决了话筒被堵的问题，进而提高用户通话的顺畅性。图4所示的电容检测装置与图2所示的电容检测装置的区别主要在于：图4所示的电容检测装置可以不独立设置电容检测单元，而是和手机触摸屏使用同一个芯片，即触摸屏芯片，该触摸屏芯片采用的是互电容原理，由于触摸屏芯片包括有多个接收端和发送端，在触摸屏的设计中， 可预留触摸屏芯片上的一个接收端和一个发送端用于话筒防堵检测。图5为本发明实施例三提供的共用触摸屏芯片的原理框图，如图5所示，触摸屏芯片上的一个接收端RX和一个发送端TX与电容检测装置的第一连接器连接，结合图4，该第一连接器通过连接线与第一触控部分和第二触控部分连接，最终实现了第一触控部分、第二触控部分与触摸屏芯片之间的电性连接。
上述实施例中均是利用电容变化来检测手指是否遮挡话筒。当手指触碰到话筒时，这时手指和触控单元会形成一个简单的平行板电容，设电容检测装置的寄生电容为Cp，手指电容为Cf，当手指没有遮挡话筒时，这时触控单元上的总电容Cx＝Cp，当手指遮挡话筒时，这时触控单元上的总电容Cx＝Cp+Cf。因此，上述实施例中电容检测装置均是利用电容的变化来检测话筒是否被遮挡。
本发明实施例四提供一种用户设备，其中该用户设备包括开关装置、控制单元、话筒和提示装置；开关装置，包括弹性件和连接件；弹性件设置在用户设备的壳体上，弹性件和话筒的送音孔相对，连接件与控制单元电性连接；弹性件和连接件之间存在间隙，当接触物体对弹性件产生压力时，弹性件因为弹性变形与连接件接触，则产生预设电平值“0”，控制单元根据检测到的预设电平值，确认话筒被遮挡住，并控制提示装置发送提示信息。可选地，所述提示装置包括所述用户设备上的扬声器、振动器或者显示器中的至少一者，因此对应的提示信息可以为语音提示、振动提示或者文字提示等。
进一步地，图6为本发明实施例四提供的开关装置与话筒配合使用的示意图，如图6所示，其中该开关装置包括：弹性件601和连接件602；弹性件601上设置有开孔，开孔和话筒的送音孔对应；其中弹性件601固定在用户设备壳体上，并通过壳体可靠接地，所述连接件602设置在所述用户设备的主板上，通过连接线与控制单元的通用输入/输出(General Purpose Input Output，简称GPIO)连接。其中，弹性件601可以是金属弹性件，比如是由铜制作成的弹性件，连接件602可以是金属连接件，比如是由铜制作成的连接件，图7为本发明实施例四提供的采用开关装置检测话筒被遮挡的原理图，如图7所示，开关装置701一端通过壳体接地，另一端连接控制单元702的GPIO。当开关装置701被按下后，即弹性件和连接件接触，则整个电路实现了接地，即电路上的电压为0V，那么对应的逻辑电平值为“0”，这时控制 单元702根据检测到的预设电平值，确认话筒被遮挡住，并控制提示装置向用户发送提示信息。
值得说明的是，本发明实施例中的控制单元可以是中央处理器(Central Processing Unit，简称CPU)。
本发明实施例提供一种用户设备，包括开关装置、控制单元、话筒和提示装置；当手指遮挡话筒时，则弹性件与连接件接触，控制单元根据检测到的预设电平值，确认话筒被遮挡住，并控制单元控制提示装置向用户发送提示信息。进而提高用户通话的顺畅性。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，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发明各实施例技术方案的范围。
