具体实施方式
下面将参照附图更详细地描述本公开的优选实施方式。虽然附图中显示了本公开的优选实施方式，然而应该理解，可以以各种形式实现本公开而不应被这里阐述的实施方式所限制。相反，提供这些实施方式是为了使本公开更加透彻和完整，并且能够将本公 开的范围完整地传达给本领域的技术人员。
如上文所述，现有技术中通过蓝牙通信方式来进行数据通信，而通过USB接口来对智能设备进行充电。不论是蓝牙连接还是USB充电，都不能够触发APP的唤起。
本公开提出，在用户将智能设备例如插入语音交互模组的卡槽之类固定部件，响应地与语音交互模组的USB对接时，由语音交互模块经由USB接口向智能设备发出APP唤起信号。换言之，以智能设备与语音交互模组的物理接触作为唤起智能设备上APP的触发条件。
由此，减少了用户在智能设备上手动唤起APP的操作，使得操作控制更加便捷，显著提升了用户体验。
图1是根据本公开第一实施例的语音交互模组100的示意性框图。
如图1所示，语音交互模组100可以包括芯片110、USB接口130、和麦克风140。
USB接口130适于与智能设备10对接。这里，智能设备10例如可以是移动电话等。
麦克风140用于获取用户发出的语音。
芯片110连接到USB接口130。芯片110例如可以是微控制单元(MCU)。
芯片110将麦克风140获取的语音发送给智能设备10，以便由智能设备10上的APP处理。该APP可以是与语音交互模组100关联的APP，也可以是预先或现场实时指定的APP。
响应于USB接口130从没有与智能设备10对接的状态转换为与智能设备10对接的状态，芯片110经由USB接口130向智能设备10发送APP唤起信号，以在智能设备10上唤起该APP。
由此，实现了便捷的APP唤起，简化了设备操作流程，显著提升了用户体验。
下面参考图2和图3描述根据本公开在智能设备10上执行的语音交互方法和语音交互装置。
图2是根据本公开可以在智能设备10上执行的语音交互方法的示意性流程图。
图3是根据本公开的语音交互装置30的示意性框图。
在步骤S210，用户可以将智能设备10插入或放置到语音交互模组100的卡槽之类的固定部件，使得智能设备10与语音交互模组100的USB接口130对接。
如上所述，此时语音交互模组100会经由USB接口130向智能设备10发送APP唤起信号。
在步骤S220，例如可以由图3所示语音交互装置30的唤起信号接收装置320，经由 USB接口130接收APP唤起信号。
在步骤S230，例如图3所示的唤起装置330，响应于接收到APP唤起信号，唤起该APP。
在步骤S240，例如图3所示的数据通信装置340，基于该APP与语音交互模组100进行数据通信。
由此，用户无需手动在智能设备10上进行唤起操作，即可以自动在智能设备10唤起APP，从而开始智能设备10和语音交互模组100之间基于该APP的数据通信。
这里，数据通信可以包括语音交互模组100和智能设备10之间双向的数据通信。例如，数据通信装置340可以接收语音交互模组100获取的语音。另一方面，数据通信装置340也可以向语音交互模组100发送控制指令和/或音频数据。
如图3所示，语音交互装置30还可以包括处理装置350。处理装置350可以对语音交互模组100获取并上传到智能设备10的语音进行分析处理。
数据通信装置340可以基于处理装置350的分析处理结果，向语音交互模组100发送控制指令和/或音频数据。
例如，用户通过语音发出例如导航请求。麦克风140可以采集用户语音。语音交互模组100将语音上传给智能设备10。智能设备10的处理装置350对该语音进行分析处理，理解其所表示的含义后，获取响应导航音频信息。然后将导航音频信息下发给语音交互模组100，然后由语音交互模组100自身的播放器或与其关联的音箱/喇叭设备等播出导航语音。
或者，用户通过语音发出例如播放音乐的请求。麦克风140可以采集用户语音。语音交互模组100将语音上传给智能设备10。智能设备10的处理装置350对该语音进行分析处理，理解其所表示的含义后，向语音交互模组100下发音乐的音频数据。然后由语音交互模组100自身的播放器或与其关联的音箱/喇叭设备等播出响应的音乐。
或者，用户通过语音发送针对语音交互模组100本身或与其关联的其它设备的控制请求。智能设备10的处理装置350对该语音进行分析处理，理解其所表示的含义后，向语音交互模组100下发控制指令，以便实现响应的控制。
另外，语音交互模组100与智能设备10之间的数据通信可以通过蓝牙通信方式来实现，也可以经由USB接口130来实现。
另一方面，语音交互模组100往往连接到电源，例如车载电源，并具有充电功能。当智能设备10与语音交互模组100的USB接口130对接时，语音交互模组100会对智能 设备10进行充电。
一般通过USB接口130来进行充电。一些情况下，也可以通过无线充电模块来进行充电。
目前有多种USB充电模式，例如，USB BC 1.2充电下行端口(CDP)模式、智能充电(SMART CHARGE)模式、QC3.0快充模式、PE快充模式等。
上述充电模式中，除了CDP模式能够支持充电同时进行USB数据通信之外，其它各模式并不支持充电同时进行USB数据通信。
为了避免数据通信与充电之间的冲突，智能设备10可以采用下面几种方式。
在语音交互模组100通过USB接口130对智能设备10进行充电的情况下，可以通过蓝牙通信方式与语音交互模组100进行数据通信。
在语音交互模组100通过无线充电方式对智能设备10进行充电的情况下，可以经由USB接口130与语音交互模组100进行数据通信。
在语音交互模组100停止通过USB接口130对智能设备10进行充电的情况下，可以经由USB接口130与语音交互模组100进行数据通信。
在语音交互模组100以支持与智能设备10经由USB接口130进行数据通信的模式，通过USB接口130对智能设备10进行充电的情况下，可以经由USB接口130与语音交互模组100进行数据通信。
下面参考图4描述根据本公开第二实施例的语音交互模组。
图4是根据本公开第二实施例的语音交互模组的示意性框图。
如图4所示，除了上文描述到的芯片110、USB接口130和麦克风140之外，语音交互模组200还可以包括USB充电控制芯片120、信号发射模块150、无线充电模块160以及过压保护模块(OVP)170。应当理解，语音交互模组200可以只包括USB充电控制芯片120、信号发射模块150、无线充电模块160以及过压保护模块(OVP)170中的任何一项或任何多项的组合。
上文中参考图1关于语音交互模组100的各项描述内容均可以适用于语音交互模组200。
USB充电控制芯片120连接到USB接口130和电源，用于通过USB接口130向智能设备10充电。过压保护模块(OVP)170可以连接在USB充电控制芯片120和电源之间，以进行过压保护。
USB充电控制芯片120的连接状态或充电模式可以具有两种状态。第一状态下，允 许芯片110与智能设备10经由USB接口130进行数据通信。第二状态可以支持高效率的充电模式，而不支持芯片110与智能设备10经由USB接口130进行数据通信。本领域技术人员应当明白，可以采用多种方式来实现USB充电控制芯片120在这两种状态之间的切换。作为示例，下文中将参考图5和图6描述两种可用来实现这两种状态的切换的例子。
可以在需要进行数据通信的时候，例如响应于数据通信请求，切换到第一状态。而在数据通信结束之后，切换到第二状态。由此，增加了操作控制的灵活性，能够显著提升用户体验。
例如，可以在智能设备10插入时，或者说，智能设备10刚与USB接口130对接时，切换到第一状态，以实现语音交互模组与智能设备10经由USB接口130的数据交互。例如，语音交互模组可以经由USB接口130向智能设备10发送唤起信号，以唤起APP。
具体说来，响应于USB接口130从没有与智能设备10对接的状态转换为与智能设备10对接的状态，可以将USB充电控制芯片120的连接状态或充电模式设置为允许芯片110与智能设备10经由USB接口130进行数据通信的第一状态。由此，芯片110可以通过USB接口130向智能设备10发送APP唤起信号。
例如，可以通过检测USB接口130处的电流信号，来判断智能设备10与USB接口130的连接状态。检测到USB接口130处的连接状态变化之后，芯片110可以发送控制信号来实现USB充电控制芯片120的连接状态或充电模式的切换。
在这种情况下，芯片110可以经由USB接口130向智能设备10发送APP唤起信号，以唤起智能设备10上的APP。
由此，可以实现APP的自动唤起，而不需要用户在智能设备10上操作。
另一方面，在经由USB接口130发送APP唤起信号之后，可以将USB充电控制芯片120的连接状态或充电模式设置为能够充电而不支持芯片110与智能设备10经由USB接口130进行数据通信的第二状态，以实现高效率的充电。可以在发送APP唤起信号之后即执行上述设置，也可以在收到智能设备10返回的APP唤起响应信号之后再执行上述设置。
另外，在智能设备10上的APP唤起之后，还可以响应于例如智能设备10上的APP和语音交互模组100之间的数据通信请求，例如语音交互模组100采集的语音上传、智能设备10向语音交互模组100下发音乐数据等，将USB充电控制芯片120的连接状态或充电模式设置为允许芯片110与智能设备10经由USB接口进行数据通信的状态。由此， 芯片110可以经由USB接口130与智能设备10进行数据通信。
响应于数据通信结束，可以将USB充电控制芯片120的连接状态或充电模式重新设置为能够充电而不支持芯片110与智能设备10经由USB接口130进行数据通信的第二状态。
另外，在智能设备10被从语音交互模组110移除之后，或者说，USB接口从与智能设备10对接的状态转换为没有与智能设备10对接的状态时，可以将USB充电控制芯片120的连接状态或充电模式设置为允许芯片110与智能设备10经由USB接口进行数据通信的状态。这样，当下次将智能设备10插入时，可以进行数据通信。
另一方面，也可以在智能设备10的电量已充满的情况下，将USB充电控制芯片120的连接状态或充电模式设置为允许芯片110与智能设备10经由USB接口130进行数据通信的状态。例如，可以通过检测USB接口130处的电流信号，来判断智能设备10的电量是否已充满。检测到智能设备10的电量已充满的情况下，芯片110可以发送控制信号来实现USB充电控制芯片120的连接状态或充电模式的切换。
由此，根据本公开的语音交互模组100可以在支持数据通信的状态和高效率充电的状态之间切换，拓展了操作控制的灵活性，可以显著提升用户体验。
语音交互模组100例如可以是车载语音交互模组，而电源可以是车载电源。
另外，芯片110可以包括数字模拟转换(ADC)模块112，用于对从USB接口130检测到的电流信号进行数字模拟转换，以得到数字检测信号。芯片110可以基于该数字检测信号来判断智能设备10与USB接口130之间的对接状态以及智能设备10的电量状态。
语音交互模组100还可以包括蓝牙模块115。蓝牙模块115可以独立于芯片110，也可以如图4所示包含在芯片110上。在APP已被唤起的情况下，可以通过蓝牙通信方式与智能设备10上的APP进行数据通信。
另外，还可以提供无线充电模块160。这样，可以在芯片110经由USB接口130与智能设备10进行数据通信的同时，对智能设备10进行无线充电。
信号发射模块150也可以连接到芯片110。芯片110将从智能设备10接收的音频数据转换成调频信号或调幅信号。信号发射模块150向附近的收音机，例如车载收音机，发送该调频信号或调幅信号，以便通过收音机的喇叭或车载音响播放相应的音频。例如，智能设备10可以例如响应于用户通过语音发出的指令，向语音交互模组200下发音乐数据。信号发射模块140向车载收音机发送对应于音乐数据的调频信号或调幅信号。车载收音机接收到调频信号或调幅信号之后，可以通过车载音响设备播放音乐。
下面参考图5和图6描述根据本公开第三和第四实施例的语音交互模组300和400。
在第三实施例和第四实施例的描述中，重点描述USB充电控制芯片120的上述连接状态或充电模式的切换方式的实现。上文中参考图1和图4关于语音交互模组100和语音交互模组200的各项描述内容均可以适用于语音交互模组300和语音交互模组400。
图5是根据本公开第三实施例的语音交互模组300的示意性框图。
在第三实施例中，对USB充电控制芯片120的交互模式进行切换，以实现上述第一状态和第二状态的切换。
这里，例如可以选用支持两种充电模式的USB充电控制芯片120。
第一充电模式对应于上述第一状态，支持芯片110与智能设备10经由USB接口130进行数据通信。另外，第一充电模式可以支持较低电流的充电。
第二充电模式对应于上述第二状态，支持比第一充电模式更高的充电电流，但是一般不支持经由USB接口130的数据通信。
例如，USB充电控制芯片120可以是CW3046芯片。相应地，第一充电模式是充电下行端口(CDP)模式，第二充电模式是智能充电模式。
芯片110可以向USB充电控制芯片120发送控制信号。USB充电控制芯片120可以响应于该控制信号在上述两种充电模式之间切换。
模式切换的时机可以与上文中参考图1关于语音交互模组100所描述的一样。
例如，响应于USB接口130从没有与智能设备10对接的状态转换为与智能设备10对接的状态，可以将USB充电控制芯片120的充电模式设置为第一充电模式。由此，允许芯片110与智能设备10经由USB接口130进行数据通信，例如可以发送APP唤起信号。
又例如，当经由USB接口130发送APP唤起信号之后，可以将USB充电控制芯片120的充电模式设置为第二充电模式。
另外，在芯片110和智能设备10之间需要进行数据通信时，可以将USB充电控制芯片120的充电模式设置为第一充电模式。而在数据通信结束后，可以将USB充电控制芯片120的充电模式设置为第二充电模式。
另外，在智能设备10被从语音交互模组110移除之后，或者在智能设备10的电量已充满的情况下，可以将USB充电控制芯片120的充电模式设置为第一充电模式。
芯片110可以通过USB通道连接到USB充电控制芯片120，从而经由USB充电控制芯片120连接到USB接口130。
芯片110的USB通道117的D+、D-可以分别连接到USB充电控制芯片120的D+、D-， 从而相应连接到USB接口130的D+、D-。
图5给出了一种示例性连接方式。其中，USB充电控制芯片120具有第一USB管脚121(例如包括D+、D-)和第二USB管脚122(例如包括D+、D-)。第一USB管脚121连接到USB接口130，第二USB管脚122经由USB通道连接到芯片110，
USB充电控制芯片120还可以包括切换开关123，连接在第一USB管脚121和第二USB管脚122之间。
在第一充电模式下，切换开关123被接通。芯片110可以连接到USB接口130。
在第二充电模式下，切换开关123被断开。芯片110到USB接口130的连接被断开。
另外，如上面参考图2所述，芯片110还可以包括模拟数字转换(ADC)模块112，连接到USB通道117，用于将来自USB通道112的电流信号转换为数字检测信号，以便芯片110基于数字检测信号确定智能设备10与USB接口130的对接状态和/或与USB接口130对接的智能设备10的电量状态。
在一个应用场景中，语音交互模组300可以实现下述操作控制：当手机插入USB时唤起APP；拔出手机时则自动切换CDP充电模式和智能充电(SMART CHARGE)模式，以实现不同电流充电。具体实现方式可以如下：
首先，USB插入手机，将充电模式切换为CDP，例如通过USB AOA协议实现数据通信实现手机APP唤起，同时支持BC1.2的电流充电(500Ma～1.5A)模式。
APP唤起后，通知语音交互模组300切换充电模式为智能充电模式，以实现不同品牌手机更大电流(2A MAX)的充电需求。此时，可以通过蓝牙通信方式来进行音频数据的传输。
手机拔出或电量充满后，可以自动切换为CDP模式，以便于下一次插入手机时以CDP模式进行手机APP唤起。
图6是根据本公开第四实施例的语音交互模组400的示意性框图。
在第四实施例中，对USB充电控制芯片120的连接状态进行切换，以实现上述第一状态和第二状态的切换。

第二状态下，芯片110与USB接口130之间的连接被切断，而在USB充电控制芯片120与USB接口130之间建立连接。
具体说来，如图6所示，语音交互模组400还可以包括切换模块190。
切换模块190连接在USB接口130与USB充电控制芯片120、芯片110之间，以便在第一连接状态和第二连接状态之间切换。上述第一状态对应于第一连接状态，上述第二状态对应于第二连接状态。
第一连接状态下，USB接口130与芯片110连接，以在芯片110和智能设备10之间进行数据通信。
第二连接状态下，USB接口130与USB充电控制芯片120连接，以对智能设备10进行充电。
切换模块190可以包括第一D+端子(D1+)和第一D-端子(D1-)、第二D+端子(D2+)和第二D-端子(D2-)以及第三D+端子(D+)和第三D-端子(D-)。
第一D+端子(D1+)和第一D-端子(D1-)分别连接到芯片110的D+端子和D-端子。
第二D+端子(D2+)和第二D-端子(D2-)分别连接到USB充电控制芯片120的D+端子和D-端子。

在第一连接状态下，第三D+端子(D+)和第三D-端子(D-)分别连接到第一D+端子(D1+)和第一D-端子(D1-)。
在第二连接状态下，第三D+端子(D+)和第三D-端子(D-)分别连接到第二D+端子(D2+)和第二D-端子(D2-)。

语音交互模组400还可以包括负载切换模块180，连接在VBUS电流检测模块175和USB充电控制芯片120的VBUS管脚之间，响应于来自芯片110的控制信号CTRL1接通或断开VBUS电流检测模块175和USB充电控制芯片120的VBUS管脚之间的连接。每当连接状态发生变化时，芯片发出控制信号CTRL1，负载切换模块180接通，重新上电。使得智能设备10能够在充电模式和数据通信模式相应切换。
芯片110可以包括模拟数字转换(ADC)模块，连接到VBUS电流检测模块175，将来自VBUS电流检测模块的电流检测信号转换为数字检测信号。芯片110基于该数字检测 信号确定智能设备10与USB接口130的对接状态和/或与USB接口130对接的智能设备10的电量状态。
芯片110可以包括第一控制管脚CTRL1、第二控制管脚CTRL2、第三控制管脚CTRL3。芯片110根据ADC模块转换得到的电流检测信号来控制第一控制管脚CTRL1、第二控制管脚CTRL2、第三控制管脚CTRL3发出的控制信号。

第三控制管脚CTRL3连接到切换模块190的使能端

以控制切换模块190的使能状态。
由此，芯片110基于VBUS的电流检测信号，发出控制信号CTRL1、CTRL2、CTRL3，相应地控制切换模块190和负载切换模块180，实现充电模式和数字通信模式之间的切换。
例如，响应于USB接口130从没有与智能设备10对接的状态转换为与智能设备10对接的状态，切换模块190可以切换为第一连接状态，USB充电控制芯片120与USB接口130之间的连接被切断，芯片110与USB接口130之间建立连接，从而允许芯片110与智能设备10经由USB接口130进行数据通信，例如可以发送APP唤起信号。
又例如，当经由USB接口130发送APP唤起信号之后，切换模块190可以切换为第二连接状态，USB充电控制芯片120与USB接口130之间建立连接，芯片110与USB接口130之间的连接被切断。
另外，在芯片110和智能设备10之间需要进行数据通信时，可以将切换模块190切换到第一连接状态。而在数据通信结束后，可以将切换模块190切换到第二连接状态。
另外，在智能设备10被从语音交互模组110移除之后，或者在智能设备10的电量已充满的情况下，可以将切换模块190切换到第一连接状态。
这种情况下，可以选择支持各种快充模式(例如QC、PE等快充模式)的USB充电控制芯片120。USB充电控制芯片120可以具有QC、PE快充协议IC。
