Description

输出音频的方法、电子设备以及存储介质 技术领域
本发明实施例涉及终端领域，尤其涉及输出音频的方法、电子设备以及存储介质。
背景技术
当前，手机除了自带的听筒，还可以连接其他音频输出设备，例如，有线耳机、蓝牙耳机、外放音响等。
现有技术中，当手机接收到用户输入的接听新来电的指示信息时，先要判断手机当前是否连接了除听筒外的其他音频输出设备；如果连接了其他音频输出设备，则通过该音频输出设备输出通话语音信号；如果未连接其他音频输出设备，则通过手机听筒输出通话语音信号。
由上可见，现有技术中，如果判断出手机连接了其他音频输出设备，则通过该音频输出设备输出通话语音信号，而手机听筒不输出通话语音信号。用户使用手机听筒接听时就听不到任何声音，此时，用户可能会误以为通话不正常而挂断电话。或者，用户先意识到自已使用错误的接听设备接听通话声音，再更换接听设备才能正常听到通话声音，用户体验不佳。
发明内容
本发明实施例提供了输出音频的方法、电子设备以及存储介质，能够在包括手机在内的电子设备连接了其他音频输出设备时提升用户体验。
第一方面，提供了一种输出音频的方法，应用于具有接近度传感器的电子设备，该方法包括：当电子设备连接有音频输出设备且有音频信号输出时， 获取接近度传感器的接近度数据；当接近度数据满足预设条件时，该电子设备的听筒输出音频信号，确定该音频输出设备的类型；根据该音频输出设备的类型，确定该音频输出设备是否输出音频信号。
由上可见，本发明实施例中，可以通过接近度数据满足预设条件来判断出用户将电子设备(例如手机)放在耳边接听，使得用户将电子设备放在耳边接听时也能通过听筒听到声音。在电子设备连接了其他音频输出设备时提升用户体验；此外，根据音频输出设备的类型，存在两种输出音频信号的方式：听筒和音频输出设备均输出音频信号，以及仅听筒输出音频信号。针对音频输出设备的类型，选择其中的一种方式输出音频信号，提高了输出音频信号的灵活性。
在一种可能的实施方式中，该方法还包括：当电子设备的听筒输出音频信号时，电子设备输出提示信息，提示信息为提示文本或提示音。
由上可见，本发明实施例中，由于通常情况下电子设备连接音频输出设备后，仅通过音频输出设备输出音频信号而听筒不输出音频信号，因此在电子设备的听筒输出音频信号时，电子设备输出提示信息，可以提高用户体验。
在一种可能的实施方式中，该方法还包括：根据音频输出设备的类型，确定该音频输出设备是否输出音频信号，包括：当音频输出设备为耳机时，该音频输出设备输出音频信号。
由上可见，本发明实施例中，当音频输出设备的类型显示该音频输出设备为耳机时，即该音频输出设备不具有外放功能时，通过听筒和耳机输出音频信号，可以在通过接近度数据满足预设条件来识别用户行为不准确的情况下，用户通过耳机也能听到声音。
在一种可能的实施方式中，根据音频输出设备的类型，确定该音频输出设备是否输出音频信号，包括：当音频输出设备为外放设备时，该音频输出设备不输出音频信号。
由上可见，本发明实施例中，当音频输出设备的类型显示该音频输出设 备具有外放功能时，仅通过听筒输出音频信号，可以保护用户隐私安全，避免其他人听到该音频信号。
在一种可能的实施方式中，接近度数据为电子设备与障碍物之间的距离，所述接近度数据满足预设条件，包括：所述电子设备与障碍物之间的的距离小于或等于预设距离。
由上可见，本发明实施例中，识别用户行为的方式简单、容易实现，判断速度快，尤其适合用户将手机放在耳边接听的具体场景。
在一种可能的实施方式中，所述接近度数据满足预设条件的持续时间大于预设时间。
由上可见，本发明实施例中，通过判断所述接近度数据满足预设条件的持续时间大于预设时间，以判断所述接近度数据满足预设条件，提高了判断所述接近度数据满足预设条件的准确率。在一种可能的实施方式中，所述接近度数据代表所述电子设备与障碍物之间的距离；所述当电子设备连接有音频输出设备且有音频信号输出时，获取所述接近度传感器的接近度数据，包括：当电子设备连接有音频输出设备且有音频信号输出时，获取预设时间段内所述接近度传感器的多个接近度数据；所述接近度数据满足预设条件，具体为：所述多个接近度数据中存在至少一个接近度数据满足第一预设条件，和/或，所述多个接近度数据随时间的变化趋势满足第二预设条件。
其中，所述多个接近度数据中存在至少一个接近度数据满足第一预设条件具体可以为：所述多个接近度数据中存在至少一个接近度数据满足小于或等于预设距离；所述多个接近度数据随时间的变化趋势满足第二预设条件具体可以为：所述多个接近度数据随时间的变化趋势满足递减的趋势。
由上可见，本发明实施例中，通过在预设时间段内获取多个接近度数据，并结合多个接近度数据的变化趋势，来判断接近度数据是否满足预设条件，从而判断用户行为的方式，可以提高判断结果的准确率。
在一种可能的实施方式中，当接近度数据满足预设条件时，电子设备的 听筒输出音频信号，包括：当接近度数据满足预设条件时，将音频信号的音频类型设置为自定义音频类型；根据预先设置的自定义音频类型与听筒之间的对应关系，通过听筒输出音频信号。
由上可见，针对通常电子设备连接了音频输出设备后的音频信号输出情况，即仅通过音频输出设备输出音频信号，而听筒不输出音频信号，本发明实施例中，为了实现在电子设备连接了音频输出设备后，当接近度数据满足预设条件时，电子设备的听筒输出音频信号这一目的，采用了自定义音频类型，并且，预先设置自定义音频类型与听筒之间的对应关系，这种实现方式比较巧妙，容易实现。
另一方面，提供了一种电子设备，该电子设备包括处理器、存储器、听筒、接近度传感器和接口电路；其中，所述存储器用于存储计算机可执行程序代码，所述程序代码包括指令，当所述处理器执行所述指令时，实现上述第一方面的方法，由于该电子设备解决问题的实施方式以及有益效果可以参见上述第一方面和第一方面的各可能的实施方式以及有益效果，因此该电子设备的实施可以参见第一方面方法的实施，重复之处不再赘述。
又一方面，本发明实施例提供了一种电子设备，该电子设备包括获取单元和处理单元；获取单元，用于当电子设备连接有音频输出设备且有音频信号输出时，获取接近度传感器的接近度数据；处理单元，用于当获取单元获取的接近度数据满足预设条件时，电子设备的听筒输出音频信号，确定音频输出设备的类型；根据音频输出设备的类型，确定该音频输出设备是否输出音频信号。基于同一发明构思，由于该电子设备解决问题的原理以及有益效果可以参见上述第一方面和第一方面的各可能的实施方式以及所带来的有益效果，因此该电子设备的实施可以参见方法的实施，重复之处不再赘述。
再一方面，本发明实施例提供了一种计算机存储介质，用于储存为上述第一方面方法设计方案所涉及所用的计算机软件指令。
相较于现有技术，本发明实施例中，可以通过接近度数据满足预设条件来判断出用户将电子设备放在耳边接听，使得用户将电子设备放在耳边接听时也能通过听筒听到声音。在电子设备连接了其他音频输出设备时提升用户体验；此外，根据音频输出设备的类型，存在两种输出音频信号的方式：听筒和音频输出设备均输出音频信号，或仅听筒输出音频信号。针对音频输出设备的类型，选择其中的一种方式输出音频信号，提高了电子设备输出音频信号的灵活性。

步骤102，当该接近度数据满足预设条件时，电子设备的听筒输出音频信号。

当该接近度数据满足预设条件，即：所述电子设备与障碍物之间的的距离小于或等于预设距离时，电子设备的听筒输出音频信号。
在一个示例中，当电子设备的听筒输出音频信号时，电子设备输出提示信息，提示信息为提示文本或提示音，用于提示用户听筒输出音频信号。
在一个示例中，当接近度数据不满足预设条件，即：所述电子设备与障碍物之间的的距离大于预设距离时，电子设备的听筒不输出音频信号，而是通过音频输出设备输出音频信号。
在一个示例中，所述接近度数据代表所述电子设备与障碍物之间的距离； 步骤101中，当电子设备连接有音频输出设备且有音频信号输出时，获取预设时间段内所述接近度传感器的多个接近度数据；步骤102中，所述接近度数据满足预设条件，具体为：所述多个接近度数据中存在至少一个接近度数据满足第一预设条件，和/或，所述多个接近度数据随时间的变化趋势满足第二预设条件，所述接近度数据满足预设条件的持续时间大于预设时间。

步骤103，确定音频输出设备的类型。
具体地，可以将音频输出设备划分为两类。一类为具有音频外放功能的音频输出设备，简称为外放设备，例如，外放音响；另一类为不具有音频外放功能的音频输出设备，例如，耳机。
本发明实施例中，对于步骤102和步骤103的执行顺序不做具体限定，可以先执行步骤102再执行步骤103，也可以先执行步骤103再执行步骤102，还可以同时执行步骤102和步骤103。
步骤104，根据音频输出设备的类型，确定该音频输出设备是否输出音频信号。
在一个示例中，当音频输出设备为耳机时，该音频输出设备输出音频信号。
在一个示例中，当音频输出设备为外放设备时，该音频输出设备不输出音频信号。
本发明实施例中，当电子设备的听筒输出音频信号时，音频输出设备可以输出音频信号，也可以不输出音频信号；在一个示例中，可以根据音频输出设备的类型确定该音频输出设备是否输出音频信号，当音频输出设备的类型标识出该音频输出设备不具有音频外放功能(例如耳机)时，该音频输出设备输出音频信号，能够避免判断失误时用户通过音频输出设备听不到声音；当音频输出设备的类型标识出该音频输出设备具有音频外放功能(例如音箱)时，该音频输出设备不输出音频信号，从而保护用户的隐私安全。
在一个示例中，可以采用如下方式使电子设备的听筒输出音频：当接近度数据满足预设条件时，将音频信号的音频类型设置为自定义音频类型；根据预先设置的自定义音频类型与听筒之间的对应关系，通过听筒输出音频信号。
在一个示例中，可以采用如下方式使电子设备的听筒和音频输出设备输出音频：当接近度数据满足预设条件且音频输出设备不具有音频外放功能时，将音频信号的音频类型设置为自定义音频类型；根据预先设置的自定义音频类型与听筒和音频输出设备之间的对应关系，通过听筒和音频输出设备输出音频信号。
本发明实施例中，可以通过接近度数据满足预设条件来判断出用户将电子设备放在耳边接听，使得用户将电子设备放在耳边接听时也能通过听筒听到声音。在电子设备连接了其他音频输出设备时提升用户体验；此外，根据音频输出设备的类型，存在两种输出音频信号的方式：听筒和音频输出设备均输出音频信号，或仅通过听筒输出音频信号。根据音频输出设备的类型，选择其中的一种方式输出音频信号，提高了电子设备输出音频信号的灵活性。
下面针对用户使用手机接听电话的应用场景为例，对本发明提供的输出音频的方法进行具体说明。
图2为本发明实施例提供的另一种输出音频的方法流程图，该方法由具有接近度传感器的手机执行，该方法包括：
步骤201，当手机接收到用户输入的接听来电的指示信息时，确认自身连接了除听筒外的其他音频输出设备，确定音频输出设备的类型。
其中，手机可以不仅检测通过有线方式连接了除听筒外的其他音频输出设备，还检测通过无线方式连接了除听筒外的其他音频输出设备。
上述音频信号包括来电铃声信号和/或通话语音信号。
电子设备根据音频信号以及所连接的其他音频输出设备动态更新音频策略表，所述音频策略表包括所述音频信号与输出所述音频信号的音频输出设备的对应关系。
例如，当电子设备收到来电响铃，通过查询所述音频策略表，配置与所述来电响铃对应的音频输出设备。
步骤202，获取接近度传感器的接近度数据。
本发明实施例中，接近度传感器具体可以为距离传感器，接近度数据可以代表手机与障碍物之间的距离。获取接近度数据的实现方法与步骤101中获取接近度数据的实现方法相同。
步骤203，当接近度数据满足预设条件时，手机的听筒输出音频信号。
本发明实施例中，通过判断接近度数据是否满足预设条件，即：判断用户是否将手机放在耳边，确定电子设备的听筒是否输出音频信号，。当接近度数据满足预设条件，即：用户将手机放在耳边时，通过手机的听筒输出音频信号。
本发明实施例中，通过检测手机与障碍物之间的距离，确定是否通过手机的听筒输出音频信号。当接近度数据满足预设条件，即：手机与障碍物之间的的距离小于或等于有效接听距离时，则确定用户将手机放在耳边，通过手机听筒输出音频信号；当接近度数据不满足预设条件，即：手机与障碍物之间的的距离大于所述有效接听距离时，则确定用户没有将手机放在耳边，手机的听筒不输出音频信号。
其中，接近度数据满足预设条件，包括：接近度数据满足预设条件的持 续时间大于预设时间，即用户将手机放在耳边的持续时间大于预设时间。当用户将手机放在耳边的持续时间大于预设时间时，通过手机听筒输出音频信号，提升检测结果的准确性。上述预设时间段例如为2秒。
步骤204，根据音频输出设备的类型，确定音频输出设备是否输出音频信号。
当所述音频输出设备为不具有音频外放功能的耳机时，所述音频输出设备输出所述音频信号。当所述音频输出设备为具有音频外放功能的设备时，所述音频输出设备不输出所述音频信号。
本发明实施例中，当手机连接有其他音频输出设备且接收到接听来电的指示信息时，检测到用户将手机放在耳边，用户可以通过听筒听到声音。并且，还可以根据音频输出设备的类型，确定该音频输出设备是否输出通话语音信号。
在一个示例中，当接近度数据满足预设条件时，将音频信号的音频类型设置为自定义音频类型；根据预先设置的所述自定义音频类型与所述听筒之间的对应关系，通过与所述自定义音频类型对应的音频输出设备输出该音频信号。例如，音频类型与音频输出设备之间的对应关系可以如表一所示。
音频类型 音频输出设备
音乐 扬声器
来电铃声 扬声器
通话语音 耳机
自定义音频类型1 听筒
自定义音频类型2 听筒+耳机
表一
本发明实施例实现了：当音频输出设备为不具有音频外放功能的耳机时，音频输出设备输出通话语音信号,即：通过听筒和耳机都输出通话语音信号，可以在判断用户将手机放在耳边的判断结果有误的情况下，用户通过耳机也 能听到通话语音，提升了用户体验。当音频输出设备为具有音频外放功能的设备时，音频输出设备不输出通话语音信号。即：仅通过听筒输出通话语音信号，可以防止其他人听到，保护了用户的隐私安全。
在一个示例中，该方法还包括：
步骤205，当接近度数据不满足预设条件时，通过音频输出设备输出音频信号。
其中，可以采用预先设置音频类型与音频输出设备之间的对应关系的方式，来实现步骤205。
下面通过一个具体的实施例来介绍本发明提供的确定音频输出设备的类型的方法。
在一个示例中，可以采用如下方式判断是否有设备以有线方式插入手机：
使用Android里提供的AudioManager中的isWiredHeadsetOn()方法；如果有设备以有线方式插入手机，该方法返回true,否则返回false。
可选的，当判断插入的是有线设备后，通过阻抗特性，区分有线耳机和有线音箱。
在一个示例中，可以采用如下方式判断是否有耳机或外放音响等音频输出设备通过蓝牙方式连接到手机：
获取手机上连接的蓝牙设备的蓝牙类型，当该蓝牙类型属于音频输出设备的蓝牙类型列表中的任意一个时，确认有音频输出设备通过蓝牙方式连接到手机。
Android本身规定了一系列的蓝牙类型，具体在BluetoothClass.Device类里面定义了一系列的蓝牙类型，包括耳机、车载设备等，手机根据连接着的蓝牙设备其自带的属性,判断蓝牙设备(BluetoothDevice)的蓝牙类型与BluetoothClass.Device里面规定的类型对比即可找到对应类型,下面是蓝牙厂商之间的约定类型。
int AUDIO_VIDEO_CAMCORDER
int AUDIO_VIDEO_CAR_AUDIO
int AUDIO_VIDEO_HANDSFREE
int AUDIO_VIDEO_HEADPHONES
int AUDIO_VIDEO_HIFI_AUDIO
int AUDIO_VIDEO_LOUDSPEAKER
int AUDIO_VIDEO_MICROPHONE
当BluetoothDevice＝＝
     AUDIO_VIDEO_CAR_AUDIO||AUDIO_VIDEO_HANDSFREE
||AUDIO_VIDEO_HEADPHONES||AUDIO_VIDEO_HIFI_AUDIO
||AUDIO_VIDEO_MICROPHONE
时，即判断耳机或外放音响等音频输出设备通过蓝牙方式连接着手机。
下面结合手机操作系统(Operating System，OS)的音频输出结构，对本发明实施例提供的输出音频的方法进行具体说明。
图3为手机OS的音频输出结构示意图。参照图3，音频输出依次经过应用层、Java框架和AudiHAL三层。
其中，Phone app为应用层的电话应用程序，该电话应用程序可以提醒用户来电，接收用户接听新来电的指示信息，并且，当判断出接近度数据满足预设条件，即手机靠近耳边时，向Java框架中的AudioService发送通知消息，该通知消息用于指示手机放在了耳边。
AudioService属于Java框架层，是Android OS里一个音频系统的大本营，它的主要功能：音量控制、音量键的处理、音频IO设备的管理。本发明实施例中，AudioService在接收到Phone app发送的通知消息后，将通知消息发送给AudioSystem。
AudioSystem属于Java框架层，充当取样音频系统资源的入口点，允许查询和访问安装在系统上的混频器，AudioSystem包括许多在不同格式间转换音频数据的方法，以及在音频文件和流之间进行转换的方法。AudioSystem 在接收到AudioService发送的通知消息后，再将上述通知消息发送给AudiHAL层的AudioPolicyManager。
AudiHAL层是Android音频底层，是同音频设备通信、控制的一个逻辑层。Android的音频管理策略为：Android为不同音频类型设置了不同的路由，根据路由选择不同的输出设备。且根据音频类型，电子设备所连接的音频输出设备创建对应关系。例如，当应用层向AudioService发送的音频类型是STREAM_MUSIC，且电子设备连接有耳机时，根据音频策略表确定音频类型为STREAM_MUSIC的声音会从耳机输出，如果音频类型是STREAM_RING，则会从耳机和扬声器(speaker)同时传出来。
根据路由为不同音频类型选择对应的输出设备主要在AudioPolicyManager的getDeviceForStrategy方法，因此通过增加自定义音频类型和修改getDeviceForStrategy的音频策略，即可以对android的音频管理策略实现自定义。
例如，新增一种音频类型STREAM_CALLING_NEW，为该音频类型配置对应的音频输出设备为手机听筒和耳机设备。
当AudioPolicyManager收到上层应用传递的通知消息时，设置音频类型为STREAM_CALLING_NEW，getDeviceForStrategy根据修改的音频策略，选择手机听筒和耳机做为输出设备。
本发明实施例提供的输出音频的方法，简单、容易实现，提升了用户体验。

处理器401、存储器402、听筒403、接近度传感器404和接口电路405；
其中，所述存储器402用于存储计算机可执行程序代码，所述程序代码包括指令，
所述处理器401调用存储在所述存储器402中的指令以实现上述图1中 的步骤101～104、图2中的步骤201～205以及输出音频的方法设计中的方案，由于该电子设备解决问题的实施方式以及有益效果可以参见上述方法的实施以及有益效果，因此该电子设备的实施可以参见方法的实施，重复之处不再赘述。
图5为本发明实施例提供的另一种电子设备结构图，该电子设备用于执行本发明实施例提供的输出音频的方法，该电子设备包括：获取单元501和处理单元502。获取单元501用于实现上述图1中的步骤101、图2中的步骤202；处理单元502用于执行上述图1中的步骤102～104、图2中的步骤201、203～205以及输出音频的方法，由于该电子设备解决问题的实施方式以及有益效果可以参见上述方法的实施以及有益效果，因此该电子设备的实施可以参见方法的实施，重复之处不再赘述。
专业人员应该还可以进一步意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，能够以电子硬件、计算机软件或者二者的结合来实现，为了清楚地说明硬件和软件的可互换性，在上述说明中已经按照功能一般性地描述了各示例的组成及步骤。这些功能究竟以硬件还是软件方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本发明的范围。
