参阅图1所示，本申请提出的第一实施例，一种音箱声道的选择方法，本申请音箱包括智能音箱，所述智能(Artificial Intelligence)音箱，简称AI音箱，智能音箱中通常设置有能够识别语音的识别模块，并且通过所述识别模块还能够分析接收到的语音具体内容，智能音箱依据语音具体内容作出相应的动作，例如开机或者关机，所述方法包括：
步骤S10，获取开启音箱的语音命令。
具体地，音箱中设置有能够识别语音的识别模块，通过识别模块能够识别出语音命令的具体操作动作，通常来说，音箱中设置有处理器，处理器控制识别模块获取开启音箱的语音命令，其中，语音命令可以是外部设备发出，也可是用户发出。例如，音箱摆放在家中的客厅位置，用户在休闲之时打算欣赏音乐，用户可以向音箱发出包含有开机的语音命令，处理器通过控制识别模块接收语音命令，并且识别出语音命令。
步骤S20，依据语音命令，确定用户所处的用户位置。
通常来说，音箱包括有两个，一个音箱开启右声道，另一音箱则开启左声道，通过左右声道的播放，形成立体声，两个音箱之间可以是蓝牙连接，也可是其它无线连接方式，两个音箱的摆放位置也是任意位置的。音箱在接收语音命令的过程中，通过用户发出语音的方位，确定得出用于位于音箱的哪一侧，另外，声音在空气中传播时，具有一定的速度，由此可以推算得出，用户距离两个音箱的距离，由此进一步确定得出用户位置。
步骤S30，依据用户位置确定距离用户较近的音箱为第一音箱，较远的音箱为第二音箱。
其中，依据用户位置推算得出用户距离两个音箱的距离，对比得出两个音箱距离用户的距离大小，定义距离用户较近的音箱为第一音箱，较远的音 箱为第二音箱。
步骤S40，依据用户位置和第一音箱的所处位置，确定第一音箱为左声道或右声道，第二音箱为剩余声道。
具体地，以距离用户较近的第一音箱为判断基准，依据用户位置分析第一音箱位于用户的左手侧还是右手侧，如果第一音箱位于用户的左手侧，则确定第一音箱为左声道，第二音箱为右声道。如果第一音箱位于用户的右手侧，则确定第一音箱为右声道，第二音箱为左声道。由此依据用户位置，第一音箱和第二音箱完成左声道和右声道的选择，保证用户能够获得良好的立体声体验效果。
除此之外，还可以距离用户较远的第二音箱为判断基准，具体来说，据用户位置分析第二音箱位于用户的左手侧还是右手侧，如果第二音箱位于用户的左手侧，则确定第二音箱为左声道，第一音箱为右声道。如果第二音箱位于用户的右手侧，则确定第二音箱为右声道，第一音箱为左声道。
再者控制音箱的处理器可设置在第一音箱中或者第二音箱中，或者第一音箱中和第二音箱中均设置有处理器。
本实施例提出的技术方案中，依据开启音箱的语音命令，确定得出用户所处的位置，即用户位置，并依据所述用户位置确定得出距离音箱的距离，其中，距离所述用户较近的音箱为第一音箱，较远的音箱为第二音箱，分析所述用户位置和所述第一音箱的所处位置关系，得出所述第一音箱为左声道或右声道，所述第二音箱为剩余声道，即所述第一音箱为左声道，所述第二音箱为右声道，或者，所述第一音箱为右声道，所述第二音箱为左声道。
参阅图2所示，在本申请的第一实施例的基础上，提出本申请的第二实施例，依据用户位置和第一音箱的所处位置，确定第一音箱为左声道或右声道，第二音箱为剩余声道的步骤S40包括：
步骤S410，获得第一接线和连接线连接形成的第一夹角，以及第二接线和连接线连接形成的第二夹角，第一夹角和第二夹角的角度范围均在0°～180°之间。
具体地，将第一音箱和第二音箱以及用户位置连接形成三角形，第一接线和连接线形成第一夹角，第二接线和连接线连接形成的第二夹角。
步骤S420，依据第一夹角和连接线位置关系，确定第一音箱为左声道或 右声道，第二音箱为剩余声道。
其中，所述连接线为所述第一音箱的所处位置和所述第二音箱的所处位置连成的线、所述第一接线为所述用户位置和所述第一音箱的所处位置连成的线、所述第二接线为所述用户位置和所述第二音箱的所处位置连成的线。俯视第一音箱和第二音箱所在空间位置，得出俯视平面，第一音箱的所处位置和第二音箱的所处位置连接成连接线，所述连接线将所述俯视平面划分为第一接听区域和第二接听区域，通过用户发出的语音命令，能够得出用户位于第一接听区域还是第二接听区域，以此便于进一步分析用户位置。
具体地，以第一音箱为判断基准，分析第一接线和连接线形成的第一夹角是连接线围绕第一音箱如何形成的，以此确定第一音箱为左声道或右声道，例如第一夹角是连接线围绕第一音箱逆时针形成的，还是顺时针形成的，如果第一夹角是连接线围绕第一音箱逆时针形成，则确定第一音箱为右声道，第二音箱为左声道，如果第二夹角是连接线围绕第一音箱顺时针形成，则确定第一音箱为左声道，第二音箱为右声道。
参阅图3所示，在本申请的第二实施例的基础上，提出本申请的第三实施例，依据第一夹角和连接线位置关系，确定第一音箱为左声道或右声道，第二音箱为剩余声道的步骤S420包括：
步骤S421，第一夹角由连接线以第一音箱逆时针转动形成，则第一音箱为右声道。
具体地，第一夹角范围在0°～180°之间，第一夹角由连接线以第一音箱逆时针转动形成，则说明用户处于第一接听区域，第一音箱位于用户的右手方向位置，由此确定得出，第一音箱为右声道，第二音箱为左声道。
步骤S422，第一夹角由连接线以第一音箱顺时针转动形成，则第一音箱为左声道。
具体地，第一夹角范围在0°～180°之间，第一夹角由连接线以第一音箱顺时针转动形成，则说明用户处于第二接听区域，第一音箱位于用户的左手方向位置，由此确定得出，第一音箱为左声道，第二音箱为右声道。
除此之外，第一夹角还可以为0°，也就是说此时，用户位于连接线上，且位于第二音箱背离第一音箱一侧，此时可以设定第一音箱为左声道，第二 音箱为右声道，也可以设定第一音箱为右声道，第二音箱为左声道。
再者，第一夹角还可以为180°，也就是说此时，用户位于连接线上，且位于第一音箱背离第二音箱一侧，此时可以设定第一音箱为左声道，第二音箱为右声道，也可以设定第一音箱为右声道，第二音箱为左声道。
参阅图4所示，在本申请的第二实施例的基础上，提出本申请的第四实施例，依据用户位置和第一音箱的所处位置，确定第一音箱为左声道或右声道，第二音箱为剩余声道的步骤S420之后包括：
步骤S430，依据第一夹角和第二夹角大小，确定用户是否在接听声音的预设范围内。
通常来说，适合用户接听声音的方向和位置是在一定的范围内的，脱离这个范围，用户接听声音的质量将会降低，无法有效的体会到立体声的效果，这个适合用户接听声音的范围为预设范围。通过确定用户是否在接听声音的预设范围内，以便进一步提示用户移动至预设范围内，保证获得立体声的体验效果。
参阅图5所示，在本申请的第四实施例的基础上，提出本申请的第五实施例，依据第一夹角和第二夹角大小，确定用户是否在接听声音的预设范围内的步骤S430包括：
步骤S431，若第一夹角和第二夹角均在0°～90°之间，则用户在接听声音的预设范围内；
也就是说，第一夹角和第二夹角均为锐角，以此保证用户获得较好的听觉体验。
步骤S432，若第一夹角或第二夹角其中一个角度大于90°，则用户不在接听声音的预设范围内。
也就是说，第一夹角或第二夹角其中一个角度为钝角，此时，判定用户不在接听声音的预设范围内。由此通过第一夹角和第二夹角的角度值的确定，能够判断得出用户是否在预设范围内。
参阅图6所示，在本申请的第五实施例的基础上，提出本申请的第六实施例，若第一夹角或第二夹角其中一个角度大于90°，则用户不在接听声音的预设范围内的步骤S432之后包括：
步骤S433，提示用于移动至接听声音的预设范围内。
具体地，可以处理器在计算得出第一夹角或第二夹角其中一个角度大于90°时，通过输出语音的形式提示用户移动至预设范围内，例如，提示用户向左或者向右移动多少距离。
此外，还可通过画面显示的形成，在画面中标识出用户位置，以及预设范围，用户由此可以以及画面移动至预设范围内，以此保证获得良好的立体声体验。
参阅图7所示，在本申请的第一实施例至第六实施例的任一实施例的基础上，提出本申请的第七实施例，依据用户位置和第一音箱的所处位置，确定第一音箱为左声道或右声道，第二音箱为剩余声道的步骤S40之后包括：
步骤S50，获取第一音箱和第二音箱的间距距离，对比间距距离和预设距离，以调整第一音箱和第二音箱的距离。
具体地，以第一音箱为判断基准，第二音箱向第一音箱发出语音，第一音箱接收第二音箱发出的语音，通过声音在空气中的传播速度，以及，声音由第二音箱到第一音箱的时间，计算得出第一音箱和第二音箱之间的距离，即间距距离。通常，间距距离过大，第一音箱和第二音箱发出的声音很难融合形成立体声，为此，设定预设距离，通过对比间距距离是否在预设距离内，如果间距距离不在预设距离内，则提示用户调整第一音箱和第二音箱的距离，使间距距离在预设距离内，保证第一音箱和第二音箱发出的声音融合形成立体声。进一步地，为了确定得出用户位于第一音箱的位置，以及第二音箱位于第一音箱的具体位置，第一音箱和第二音箱均设置有两个拾音麦克风，比如，用户向第一音箱发出语音命令，通过两个麦克风接收声音的时间差，可计算得出用户的大致位置。例如，第一音箱设置有两个麦克风，其中一个麦克风先接收到用户声音，另一个麦克风后接收到用户声音，则用户靠近先接收到用户声音麦克风，以此根据两个麦克风接收到用户声音的时间差，推算用户位置。更进一步地，可知，麦克风设置的数量越多，确定用户的位置越准确。
此外，还可通过第二音箱上设置红外发射器，第一音箱设置红外接收器，第二音箱向第一音箱发射红外光线，以此来测量第一音箱和第二音箱的间距距离。
参阅图8所示，在本申请的第七实施例的基础上，提出本申请的第八实施 例，依据用户位置确定距离用户较近的音箱为第一音箱，较远的音箱为第二音箱的步骤S50包括：
步骤S510，依据语音命令，计算得出用户与音箱的距离分别为第一距离和第二距离；
步骤S520，对比第一距离和第二距离大小，确定距离用户较近的音箱为第一音箱，较远的音箱为第二音箱。
具体地，通过声音在空气中的传播速度，以及语音命令分别传播至第一音箱和第二音箱的时间，计算得出用户与两个音箱的距离，得出用户与第一音箱的距离为第一距离，用户与第二音箱的距离为第二距离。
此外，还可设定用户距离第一音箱的标准距离为第一标准距离，用户距离第二音箱的标准距离为第二标准距离，用户位置在第一标准距离和第二标准距离内能够获得更好的立体声体验，也就是，第一距离在第一标准距离范围内，第二距离在第二标准距离范围内。不同型号的音箱第一标准距离和第二标准距离范围不同。
本申请还提供一种音箱声道的选择装置，参阅图9和图10所示，本申请音箱包括智能音箱，所述智能音箱简称AI音箱，智能音箱中通常设置有能够识别语音的识别模块，并且通过所述识别模块还能够分析接收到的语音具体内容，智能音箱依据语音具体内容作出相应的动作，例如开机或者关机，所述装置包括：开启模块100、确定模块200和选择模块300。

确定模块200，用于依据所述语音命令，确定用户30所处的用户位置；通常来说，音箱包括有两个，一个音箱开启右声道，另一音箱则开启左声道，通过左右声道的播放，形成立体声，两个音箱之间可以是蓝牙连接，也可是 其它无线连接方式，两个音箱的摆放位置也是任意位置的。音箱在接收语音命令的过程中，通过用户30发出语音的方位，确定得出用于位于音箱的哪一侧，另外，声音在空气中传播时，具有一定的速度，由此可以推算得出，用户30距离两个音箱的距离，由此进一步确定得出用户位置。
所述确定模块200，还用于依据所述用户位置确定距离所述用户30较近的音箱为第一音箱10，较远的音箱为第二音箱20；其中，依据用户位置推算得出用户30距离两个音箱的距离，对比得出两个音箱距离用户30的距离大小，定义距离用户30较近的音箱为第一音箱10，较远的音箱为第二音箱20。
选择模块300，用于依据所述用户位置和所述第一音箱10的所处位置，确定所述第一音箱10为左声道或右声道，所述第二音箱20为剩余声道。具体地，以距离用户30较近的第一音箱10为判断基准，依据用户位置分析第一音箱10位于用户30的左手侧还是右手侧，如果第一音箱10位于用户30的左手侧，则确定第一音箱10为左声道，第二音箱20为右声道。如果第一音箱10位于用户30的右手侧，则确定第一音箱10为右声道，第二音箱20为左声道。由此依据用户位置，第一音箱10和第二音箱20完成左声道和右声道的选择，保证用户30能够获得良好的立体声体验效果。
除此之外，还可以距离用户30较远的第二音箱20为判断基准，具体来说，据用户位置分析第二音箱20位于用户30的左手侧还是右手侧，如果第二音箱20位于用户30的左手侧，则确定第二音箱20为左声道，第一音箱10为右声道。如果第二音箱20位于用户30的右手侧，则确定第二音箱20为右声道，第一音箱10为左声道。
再者控制音箱的处理器可设置在第一音箱10中或者第二音箱20中，或者第一音箱10中和第二音箱20中均设置有处理器。
本实施例提出的技术方案中，依据开启音箱的语音命令，确定得出用户30所处的位置，即用户位置，并依据用户位置确定得出距离音箱的距离，其中，距离所述用户30较近的音箱为第一音箱10，较远的音箱为第二音箱20，分析所述用户位置和所述第一音箱10的所处位置关系，得出所述第一音箱10为左声道或右声道，所述第二音箱20为剩余声道，即所述第一音箱10为左声道，所述第二音箱20为右声道，或者，所述第一音箱10为右声道，所述第二音箱20为左声道。
进一步地，所述选择模块300还用于获得第一接线12和连接线11连接形成的第一夹角10a，以及第二接线21和连接线11连接形成的第二夹角20a，第一夹角10a和第二夹角20a的角度范围均在0°～180°之间。具体地，将第一音箱10和第二音箱20以及用户位置连接形成三角形，第一接线12和连接线11形成第一夹角10a，第二接线21和连接线11连接形成的第二夹角20a。
所述选择模块300还用于依据第一夹角10a和连接线位置关系，确定第一音箱10为左声道或右声道，第二音箱20为剩余声道。具体地，以第一音箱10为判断基准，分析第一接线12和连接线11形成的第一夹角10a是连接线围绕第一音箱10如何形成的，以此确定第一音箱10为左声道或右声道，例如第一夹角10a是连接线围绕第一音箱10逆时针形成的，还是顺时针形成的，如果第一夹角10a是连接线围绕第一音箱10逆时针形成，则确定第一音箱10为右声道，第二音箱20为左声道，如果第二夹角20a是连接线围绕第一音箱10顺时针形成，则确定第一音箱10为左声道，第二音箱20为右声道。
其中，连接线11为第一音箱10的所处位置和第二音箱20的所处位置连成的线、第一接线12为用户位置和第一音箱10的所处位置连成的线、第二接线21为用户位置和第二音箱20的所处位置连成的线。俯视第一音箱10和第二音箱20所在空间位置，得出俯视平面，第一音箱10的所处位置和第二音箱20的所处位置连接成连接线11，所述连接线11将所述俯视平面划分为第一接听区域110和第二接听区域120，通过用户30发出的语音命令，能够得出用户30位于第一接听区域110还是第二接听区域120，以此便于进一步分析用户位置。
具体地，以第一音箱10为判断基准，分析第一接线12和连接线11形成的第一夹角10a是连接线11围绕第一音箱10如何形成的，以此确定第一音箱10为左声道或右声道，例如第一夹角10a是连接线11围绕第一音箱10逆时针形成的，还是顺时针形成的，如果第一夹角10a是连接线11围绕第一音箱10逆时针形成，则确定第一音箱10为右声道，第二音箱20为左声道，如果第二夹角是连接线11围绕第一音箱10顺时针形成，则确定第一音箱10为左声道，第二音箱20为右声道。
进一步地，选择模块300还用于第一夹角10a由连接线以第一音箱逆时针转动形成，则第一音箱10为右声道。具体地，第一夹角10a范围在0°～180°之间，第一夹角10a由连接线11以第一音箱10逆时针转动形成，则说明用户30 处于第一接听区域110，第一音箱10位于用户30的右手方向位置，由此确定得出，第一音箱10为右声道，第二音箱20为左声道。
选择模块300还用于第一夹角10a由连接线11以第一音箱10顺时针转动形成，则第一音箱10为左声道。具体地，第一夹角10a范围在0°～180°之间，第一夹角10a由连接线11以第一音箱10顺时针转动形成，则说明用户30处于第二接听区域120，第一音箱10位于用户30的左手方向位置，由此确定得出，第一音箱10为左声道，第二音箱20为右声道。
除此之外，第一夹角10a还可以为0°，也就是说此时，用户30位于连接线11上，且位于第二音箱20背离第一音箱10一侧，此时可以设定第一音箱10为左声道，第二音箱20为右声道，也可以设定第一音箱10为右声道，第二音箱20为左声道。
再者，第一夹角10a还可以为180°，也就是说此时，用户30位于连接线11上，且位于第一音箱10背离第二音箱20一侧，此时可以设定第一音箱10为左声道，第二音箱20为右声道，也可以设定第一音箱10为右声道，第二音箱20为左声道。
进一步地，选择模块300还包括对比单元310，对比单元310用于依据第一夹角10a和第二夹角20a大小，确定用户30是否在接听声音的预设范围内。通常来说，适合用户30接听声音的方向和位置是在一定的范围内的，脱离这个范围，用户30接听声音的质量将会降低，无法有效的体会到立体声的效果，这个适合用户30接听声音的范围为预设范围。通过确定用户30是否在接听声音的预设范围内，以便进一步提示用户30移动至预设范围内，保证获得立体声的体验效果。
进一步地，所述对比单元310还用于依据第一夹角10a和第二夹角20a大小，确定用户30是否在接听声音的预设范围内。具体地若第一夹角10a和第二夹角20a均在0°～90°之间，则用户30在接听声音的预设范围内；也就是说，第一夹角10a和第二夹角20a均为锐角，以此保证用户30获得较好的听觉体验。
若第一夹角10a或第二夹角20a其中一个角度大于90°，则用户30不在接听声音的预设范围内。也就是说，第一夹角10a或第二夹角20a其中一个角度为钝角，此时，判定用户30不在接听声音的预设范围内。由此通过第一夹角10a和第二夹角20a的角度值的确定，能够判断得出用户30是否在预设范围内。
进一步地，选择模块300还包括提示单元320，所述提示单元320用于提示用于移动至接听声音的预设范围内。具体地，可以处理器在计算得出第一夹角10a或第二夹角20a其中一个角度大于90°时，通过输出语音的形式提示用户30移动至预设范围内，例如，提示用户30向左或者向右移动多少距离。
进一步地，音箱声道的选择装置还包括调整模块400，调整模块400用于获取第一音箱10和第二音箱20的间距距离，对比间距距离和预设距离，以调整第一音箱10和第二音箱20的距离。具体地，以第一音箱10为判断基准，第二音箱20向第一音箱10发出语音，第一音箱10接收第二音箱20发出的语音，通过声音在空气中的传播速度，以及，声音由第二音箱20到第一音箱10的时间，计算得出第一音箱10和第二音箱20之间的距离，即间距距离。通常，间距距离过大，第一音箱10和第二音箱20发出的声音很难融合形成立体声，为此，设定预设距离，通过对比间距距离是否在预设距离内，如果间距距离不在预设距离内，则提示用户30调整第一音箱10和第二音箱20的距离，使间距距离在预设距离内，保证第一音箱10和第二音箱20发出的声音融合形成立体声。此外，还可通过第二音箱20上设置红外发射器，第一音箱10设置红外接收器，第二音箱20向第一音箱10发射红外光线，以此来测量第一音箱10和第二音箱20的间距距离。
进一步地，调整模块400还用于依据语音命令，计算得出用户30与音箱的距离分别为第一距离和第二距离；对比第一距离和第二距离大小，确定距离用户30较近的音箱为第一音箱10，较远的音箱为第二音箱20。
具体地，通过声音在空气中的传播速度，以及语音命令分别传播至第一音箱10和第二音箱20的时间，计算得出用户30与两个音箱的距离，得出用户30与第一音箱10的距离为第一距离，用户30与第二音箱20的距离为第二距离。进一步地，为了确定得出用户位于第一音箱10的位置，以及第二音箱20位于第一音箱10的具体位置，第一音箱10和第二音箱20均设置有两个拾音麦克风，比如，用户向第一音箱10发出语音命令，通过两个麦克风接收声音的时间差，可计算得出用户的大致位置。例如，第一音箱10设置有两个麦克风，其中一个麦克风先接收到用户声音，另一个麦克风后接收到用户声音，则用户靠近先接收到用户声音麦克风，以此根据两个麦克风接收到用户声音的时间差，推算用户位置。更进一步地，可知，麦克风设置的数量越多，确定用户的位 置越准确。
此外，还可设定用户30距离第一音箱10的标准距离为第一标准距离，用户30距离第二音箱20的标准距离为第二标准距离，用户位置在第一标准距离和第二标准距离内能够获得更好的立体声体验，也就是，第一距离在第一标准距离范围内，第二距离在第二标准距离范围内。不同型号的音箱第一标准距离和第二标准距离范围不同。
