具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请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 申请实施例一部分实施例，而不是全部的实施例。基于本申请实施例中的实施例，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，都属于本申请实施例保护的范围。
在实际应用中，手机中包括电池和主板，电池和主板连接，电池向主板供电，保障手机正常工作。在手机落入水之后，如果电池继续向主板供电，则会导致主板烧坏。
为了避免在手机落入水之后烧坏主板，通常采用一些检测方法，来检测手机是否落水，若检测到手机落水，则控制电池停止向主板供电。
在现有技术中，在主板设置湿度传感器，在手机的壳体上设置湿度开孔，湿度传感器通过湿度开孔采集环境湿度，主板上的处理器获取环境湿度，当根据环境湿度确定手机落水时，控制电池停止向主板供电。
在上述相关技术中，温度传感器的价格较高，使得手机的成本较高。进一步地，手机的壳体设置湿度开孔，增加了壳体上的开孔数量。而且温度传感器的体积大，在主板上的占用面积较大。
为了降低手机的成本，减少手机壳体上的开孔数量，减少在主板上的占用面积，发明人想到不使用湿度传感器，来检测手机是否落水。为了避免使用湿度传感器，发明人发现在手机落水之后，水先通过壳体上的开孔(例如扬声器)的进入腔体(例如扬声器的音腔)内，可以通过检测腔体内是否有水，实现检测手机是否落水的目的。进一步地，为了实现检测腔体内是否有水，发明人设计了一个检测单元，检测单元中包括两个间隔设置的导电体，当水较多，使得两个导电体导通时，检测单元输出检测信号，使得处理器可以根据检测信号控制电池停止向主板供电。
下面以具体地实施例对本申请实施例的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。

终端设备：是一种具有无线收发功能的设备。终端设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、车载终端设备、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备、可穿戴终端设备等。本申请实施例所涉及的终端设备还可以称为终端、用户设备(user equipment， UE)、接入终端设备、车载终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程终端设备、移动设备、UE终端设备、无线通信设备、UE代理或UE装置等。终端设备也可以是固定的或者移动的。
在一种可能的设计中，腔体12为音腔，开孔11为音频开孔，音腔通过音频开孔和壳体10外部连通。音频开孔包括扬声器开孔和/或拾音器开孔，还可以包括喇叭开孔。
在一种可能的设计中，导电体包括金属丝或探针。
在检测单元20中，两个导电体可以设置在腔体12的同一个侧壁上，也可以设置在不同的侧壁上。
两个导电体中的任意一个导电体与控制器30连接。
例如，两个导电体分别为导电体201和导电体202时，导电体201可以与控制器30连接。
需要说明的是，图1是以两个导电体设置在腔体12的同一个侧壁上、导电体201与控制器30连接为例进行示例性说明的。
可选地，检测信号为检测电压、或者检测电流。可选地，供电状态为正常状态、或者停止状态。正常状态表示电源模块40为电路板组件供电。停止状态表示电源模块40不为电路板组件供电。
当检测信号为检测电压时，控制器30根据检测电压和电压阈值确定控制电源模块40的供电状态。
例如，当终端设备落入水中时，检测电压小于电压阈值，控制器30控制电源模块40的供电状态为停止状态；
当终端设备未落入水中时，检测电压等于电压阈值，控制器30控制电源模块40的供电状态为正常状态。
电压阈值可以为5伏、12伏等。
当检测信号为检测电流时，控制器30根据检测电流和电流阈值确定控制电源模块40的供电状态。
例如，当终端设备落入水中时，检测电流大于电流阈值，控制器30控制电源模块40的供电状态为停止状态；
当终端设备未落入水中时，检测电流等于电流阈值，控制器30控制电源模块40的供电状态为正常状态。
电流阈值可以为0安培。
当检测电压小于电压阈值、或者检测电流大于电流阈值时，控制器30向电源模块40发送关断信号，使得电源模块40根据关断信号停止工作，从而实现控制电源模块40的供电状态为停止状态。
当检测电压等于电压阈值、或者检测电流等于电流阈值等，控制器30无需向电源模块40发送任何信号，即可控制电源模块40的供电状态为正常状态。
在图1实施例提供的终端设备中，当终端设备落入水中时，水从开孔11进入腔体12，腔体12内两个间隔设置的导电体相互导通，在两个间隔设置的导电体相互导通时，检测单元20输出检测信号，控制器30根据检测信号控制电源模块40的供电状态，无需使用湿度传感器，降低了终端设备的成本，减少在主板上的占用面积，避免在壳体10上设置 湿度开孔，减少壳体10上的开孔数量。
与现有技术不同，在现有技术中，通过湿度传感器检测手机是否落水的方法通常包括：处理器获取湿度传感器采集得到的环境湿度，当环境湿度大于预设湿度阈值时，认为手机落入水中，此时控制电池停止向主板供电。
在实际应用中，当手机所在的环境湿度较大大于预设湿度阈值时，通过上述现有技术，会使得处理器误认为手机落入水中。
而在本申请实施例中，当终端设备落入水中时，腔体12内两个间隔设置的导电体相互导通，检测单元20输出检测信号，控制器30根据检测信号控制电源模块40的供电状态，无需使用湿度传感器，避免终端设备所在的环境湿度较大时、控制器30误认为终端设备落入水。
在上述实施例的基础上，下面结合图2～图5对本申请实施例提供的腔体进行说明。
图2为本申请实施例提供的腔体的结构示意图一。如图2所示，在腔体12内，两个导电体延伸到腔体12内部分的端部紧贴腔体12的内壁。
当腔体12内有水时，导电体201和导电体202相互导通。
图3为本申请实施例提供的腔体的结构示意图二。如图3所示，在腔体12内，腔体12的内侧设置有防水膜13，导电体201和导电体202贯穿防水膜13延伸至腔体12内。
防水膜13用于在手机落入水中之后，阻止水通过开孔11进入终端设备内部。
具体的，在终端设备落入水中之后，防水膜13阻止水通过开孔11进入终端设备内部，使得贯穿防水膜13的导电体201和导电体202互相导通。
在一种可能的设计中，防水膜13位于两个导电体之间的部位上覆盖有亲水膜14。亲水膜14用于将水分引导至导电体201和导电体202处，当导电体201和导电体202处的水分较多时，导电体201和导电体202相互导通。
在一种可能的设计中，两个导电体贯穿亲水膜14延伸至腔体12的内部。具体的请参见图4实施例。
图4为本申请实施例提供的腔体的结构示意图三。在图3的基础上，如图4所示，在腔体12内，导电体201和导电体202贯穿亲水膜14延伸至腔体12的内部。
在一种可能的设计中，两个导电体贯穿亲水膜14、两个导电体贯穿亲水膜14的端部紧贴亲水膜14的外壁15。具体的，请参见图5实施例。
图5为本申请实施例提供的腔体的结构示意图四。在图3的基础上，如图5所示，在腔体12内，导电体201和导电体202贯穿亲水膜14，导电体201和导电体202贯穿亲水膜14的端部紧贴亲水膜14的外壁15。
在上述实施例的基础上，下面对本申请实施例中的检测单元20进行说明，具体的，请参见图6实施例。
图6为本申请实施例提供的终端设备的结构示意图二。例如图1和图5的基础上，如图6所示，检测单元20还包括：电源和电阻；其中，
电阻的一端与电源连接，电阻的另一端分别与控制器和一个导电体连接，另一个导电体接地；
检测单元20，具体用于在两个导电体相互导通时，根据电阻的电压变化值，输出检测信号。
需要说明的是，图6是以电阻的另一端与导电体201连接，导电体202接地为例进行说明的。
电源的输出电压可以等于上述电压阈值。
例如，当检测信号为检测电压时，若导电体201和导电体202没有相互导通，检测单元20输出的检测电压等于电压阈值；
若导电体201和导电体202相互导通，检测单元20输出的检测电压小于电压阈值。
在实际应用中，可以在控制器30中预先存储电压阈值，控制器30在获取到检测电压之后，若确定电压阈值大于检测电压，则控制电源模块40的供电状态为停止状态。
控制器30可以为中央处理器(central processing unit，CPU)、微控制单元(Microcontroller Unit，MCU)等。
当控制器30为CPU时，CPU上设置有通用型输入输出(General-purpose input/output，GPIO)/模数转换(Analogue-to-Digital Conversion，ADC)引脚，GPIO/ADC引脚与检测单元20中的导电体例如导电体201连接，CPU通过GPIO/ADC引脚，得到检测电压。
图6实施例提供的终端设备具有的有益效果与上述实施例相同，此处不再赘述。
在上述实施例的基础上，下面对图7的对本申请中控制器30所执行的方法进行说明。具体的，请参见图7实施例。
图7为本申请实施例提供的控制器的工作方法流程示意图。如图7所示，该方法包括：
S701、获取检测单元输出的检测电压。
S702、判断检测电压是否小于电压阈值。
若是，则执行S703，否则执行S704。
S703、确定终端设备落入水中，向电源模块40发送关断信号。
关断信号用于使电源模块40停止工作，从而实现控制电源模块40的供电状态为停止状态。
S704、确定终端设备未落入水中。
需要说明的是，在S704之后，重复执行S701～S704。
与现有技术不同，在现有技术中，在手机中设置加速度传感器，通过加速度传感器采集手机的加速度，当加速度等于重力加速度时，处理器确定手机落水中，进而切断电源。在实际应用中，当用户把手机扔到床、或者沙发等地方时，加速度等于重力加速度，处理器会误认为手机落水中。
而在本申请实施例中，获取检测单元输出的检测电压，在检测电压小于电压阈值时，向电源模块40发送关断信号，控制电源模块40的供电状态为停止状态，从而实现切断电源，可以避免控制器误认为手机落水中。
在上述实施例的基础上，下面结合图8对本申请实施例提供的电源模块40进行说明，具体的，请参见图8实施例。
图8为本申请实施例提供的终端设备的结构示意图三。在图6的基础上，如图8所示，电源模块40包括：电源管理单元和与电源管理单元连接的电池；电源管理单元和控制器连接；
控制器用于将检测信号传输至电源管理单元；
电源管理单元用于根据检测信号控制电池的供电状态。
终端设备中还包括其他工作模块，其他工作模块位于电路板组件上，电池通过电源管理单元向其他工作模块供电，保障终端设备正常工作。
例如，当检测信号为检测电压时，若电源管理单元确定检测电压小于电压阈值，则电源管理单元自动停止工作，控制电池的供电状态为停止状态。
例如，当检测信号为检测电流时，若电源管理单元确定检测电流大于电流阈值，则电源管理单元自动停止工作，控制电池的供电状态为停止状态。
当电源管理单元自动停止工作时，电池无法向其他工作模块供电，使得其他工作模块停止工作，进而避免终端设备中的主板被烧坏。
在一种可能的设计中，电源管理单元还可以直接获取检测单元20输出的检测信号，根据检测信号控制电池的供电状态。
图8实施例提供的终端设备具有的有益效果与上述实施例相同，此处不再赘述。
