 本发明的实施方式
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作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。
为解决传统技术中通过人工手动方式调整智能设备的声音外放模式，由于模式调整效率低下导致隐私风险的存在，降低用户体验。
基于上述问题，在本实施例中，特提出了一种声音外放的模式切换方法。该方法的实现可依赖于计算机程序，该计算机程序可运行于基于冯诺依曼体系的计算机系统之上。
如图1所示，本实施例提供的声音外放的模式切换方法，应用于发声系统，该发声系统设置有第一外放模式和第二外放模式，该声音外放的模式切换方法具体包括以下步骤：
步骤102：在预设的时间周期内，获取当前环境参数值。
其中，第一外放模式和第二外放模式是发声系统预先设置的两种声音外放模式，更具体地，第一外放模式是指可以应用在公开场合的声音外放模式，即分享外放模式，在第一外放模式下，用户以及其周边人均能听到外放声音，第二外放模式是指需要注意隐私或者声音打扰敏感的场合的声音外放模式，即隐私外放模式，在第二外放模式下，仅用户可以听到明显的外放声音且周围的人听不到外放声音，或者外放声音很小。当前环境参数值是一种用于反映当前环境对声音敏感程度的指标数据，该当前环境参数可以是当前环境的振动(强弱、频率)、环境光的明暗、周围声音(响度、频率)、位置(所在位置、以及位置变化速度)等信息的一种、或多种的组合。在预设的时间周期内是指每隔一个特定的时间，获取一次当前环境参数值，该预设的时间周期内可以是5分钟、6分钟或者7分钟等，具体可根据实际应用场合确定，此处不做具体限定。可以理解地，通过在预设的时间周期内，获取当前环境参数值，以便后续基于该当前环境参数值作出声音外放模式切换决策。
步骤104：将当前环境参数值与预设的环境特征值进行比较，判断当前环境参数值对应的环境状态，环境状态包括第一环境和第二环境。
其中，预设的环境特征值是预先设定的用于对当前环境参数值对应的环境状态进行判定的阈值，该预设的环境特征值可以是一个阈值，也可以是多个阈值，即每个环境状态对应一个阈值。环境状态包括第一环境和第二环境，也即两种不同的环境状态。具体地，比较当前环境参数值与预设的环境特征值大小，根据比较结果，判断当前环境参数值对应的环境状态。本实施例中，通过将当前环境参数值与预设的环境特征值进行比较，判断当前环境参数值对应的环境状态是第一环境还是第二环境，实现了对所述当前环境参数值对应的环境状态自动检测，避免用户对环境判断的耗时耗力，有利于提高后续声音外放模式切换的效率。
步骤106：若环境状态为第一环境，将发声系统的声音外放的模式设置为第一外放模式。
具体地，在判定当前环境参数值对应的环境状态为第一环境后，将发声系统的声音外放的模式设置为与第一环境对应的声音外放模式，即第一外放模式，从而实现了对发声系统的声音外放模式的自动切换，避免了用户需手动对声音外放模式的切换或者设置的操作。在第一环境下，用户能够以分享外放模式进行声音外放，使得用户能够自然地欣赏声音外放，提升了用户体验。
步骤108：若环境状态为第二环境，将发声系统的声音外放的模式设置为第二外放模式。
具体地，在判定当前环境参数值对应的环境状态为第二环境后，将发声系统的声音外放的模式设置为与第二环境对应的声音外放模式，即第二外放模式，从而实现了对发声系统的声音外放模式的自动实时切换，提高了声音外放模式切换的便捷性。进一步地，在第二环境下，用户能够以隐私外放模式进行声音外放，使得用户能够在不打扰周围人的情况下，能够自然地欣赏声音外放，并且保护了用户的隐私，提升了用户体验。并且，避免了用户手动切换不及时，或者手动随意切换声音外放模式造成的隐私风险。
值得说明的是，本实施例中的第一环境和第二环境还可以继续划分为多个第一子环境和第二子环境，如第一A环境、第一B环境、第一C环境等，第二A环境、第二B环境、第二C环境等，相应地，第一外放模式和第二外放模式可以对应划分为第一A级外放模式、第一B级外放模式、第三C级外放模式等，第二A级外放模式、第二B级外放模式、第二C级外放模式等。进一步地，本实施例中的第一环境和第二环境，以及第一外放模式和第二外放模式仅为示例，并不作为限定本申请的依据。
上述声音外放的模式切换方法，通过在预设的时间周期内，获取当前环境参数值；将当前环境参数值与预设的环境特征值进行比较，判断当前环境参数值对应的环境状态，环境状态包括第一环境和第二环境；若环境状态为第一环境，将发声系统的声音外放的模式设置为第一外放模式；若环境状态为第二环境，将发声系统的声音外放的模式设置为第二外放模式，实现了对发声系统的声音外放模式的自动实时切换，提高了声音外放模式切换的便捷性，避免了用户手动切换不及时，或者手动随意切换声音外放模式造成的隐私风险。使得用户能够在不打扰周围人的情况下，能够自然地欣赏声音外放，并且保护了用户的隐私，提升了用户体验。
如图2所示，在一个实施例中，在将当前环境参数值与预设的环境特征值进行比较之前，还包括：
步骤110：分别采集第一环境对应的第一参数以及第二环境对应的第二参数；
步骤112：根据预设的规则对第一参数和第二参数进行处理，得到预设的环境特征值。
其中，第一参数是用于表征第一环境的指标数据，第二参数是用于表征第二环境的指标数据。预设的规则可以是预先自定义的第一环境与第一参数的映射关系，以及第二环境与第二参数的映射关系。具体地，通过检测设备自动采集第一环境对应的第一参数和第二环境对应的第二参数，根据预设的规则对第一参数和第二参数进行处理，得到预设的环境特征值，实现了通过自定义的方法确定该预设的环境特征值，以便后续对当前环境参数值对应的环境状态的判断更加全面和准确。
在一个实施例中，当前环境参数值包括：当前环境的振动值、亮度值、声音值和/或位置值。
具体地，当前环境的振动值可以通过智能设备上安装的陀螺仪和加速度计进行感知并由智能设备处理器进行计算得到，当前环境的亮度值可以通过智能设备上安装的环境光传感器对周围光强进行感知并由智能设备处理器进行计算得到，当前环境的声音值可以通过智能设备上安装的麦克风捕捉周围声音，并对声音信号进行计算得到声音响度，当前环境的亮度值可以通过智能设备上安装的GPS传感器来进行感知并由智能设备处理器进行计算得到。可以理解地，当前环境参数值包含有至少四个维度的数据，能够保证当前环境参数值的全面性和准确度。
如图3所示，在一个实施例中，获取当前环境参数值，包括：
步骤102A：获取当前环境的振动值、亮度值、声音值、位置值中的至少一项作为候选参数值；
步骤102B：按照预设的算法对候选参数值进行处理，得到当前环境参数值。
其中，预设的算法可以是直接对候选参数值进行求和计算，也可以是对候选参数值进行加权求和计算，即预先设置各个候选参数值的权重，根据对应的权重进行计算，得到当前环境参数值。作为本实施例的优选，采用加权求和的方法进行处理，从而充分考虑了各个候选参数值对于当前环境参数的影响，以提高当前环境参数值的准确性。
需要说明的是，本实施例中的当前环境参数值是通过按照预设的算法对候选参数值进行处理得到的，相应地，预设的环境特征值则按照该预设的算法进行确定，从而保证当前环境参数值与预设的环境特征值的数据类型相同，以便后续的判断比较。
如图4所示，在一个实施例中，将当前环境参数值与预设的环境特征值进行比较，判断所述当前环境参数值对应的环境状态的步骤，还包括：
步骤104A：分别判断当前环境的振动值、亮度值、声音值、位置值是否满足相应的预设的环境特征值；
步骤104B：若当前环境的振动值、亮度值、声音值、位置值中的任一项不满足相应的预设的环境特征值时，确定当前环境参数值对应的环境状态为第一环境；
步骤104C：若当前环境的振动值、亮度值、声音值、位置值中的每一项均满足相应的预设的环境特征值时，确定当前环境参数值对应的环境状态为第二环境。
在这个实例中，如果当前环境的振动值、亮度值、声音值、位置值中的任一项不满足相应的预设的环境特征值，即当前环境的振动值、亮度值、声音值、位置值中只要有一个数据不满足条件，则直接判定当前环境参数值对应的环境状态为第一环境；当前环境的振动值、亮度值、声音值、位置值中的每一项均满足相应的预设的环境特征值时，确定当前环境参数值对应的环境状态为第二环境。可以理解地，第二环境的判定标准高于第一环境的判定标准，能够保证在一定程度上减少对别人的打扰，降低隐私风险。
在一个具体实施方式中，若当前环境的振动值、亮度值、声音值、位置值相应的预设的环境特征值分别为10m/s2、70cd、50dB、60km/h，当前环境的振动值、亮度值、声音值、位置值分别为15m/s2、80cd、60dB、70km/h时，确定当前环境参数值对应的环境状态为第二环境。
在一个实施例中，将发声系统的声音外放的模式设置为第一外放模式，将发声系统的声音外放的模式设置为第二外放模式的步骤，还包括：
声音外放模组切换至第一外放模式时，声音信号以第一指向角度进行传播；声音外放模式切换至第二外放模式时，声音信号以第二指向角度进行传播；第一指向角度大于第二指向角度。
在这个实施例中，通过设置指向角度确定声音外放模式，指向角度越大，声音外放模式越趋向于外放分享模式，指向角度越小，声音外放模式越趋向于外放隐私模式。如图5所示，为第一指向角度与第二指向角度的示意图。通过第一指向角度的声波进行声音信号传播，以使声音外放模式切换至第一外放模式，通过第二指向角度的声波进行声音信号传播，以使声音外放模式切换至第二外放模式，第一指向角度大于第二指向角度，从而保证用户在第一环境下设置的第一外放模式下自然地使用声音外放，且在第二环境下设置的第二外放模式下自然地使用声音外放，并且保护了用户的隐私。
进一步地，若第一外放模式和第二外放模式分别对应划分为第一A级外放模式、第一B级外放模式、第三C级外放模式等，第二A级外放模式、第二B级外放模式、第二C级外放模式时，可以通过预先配置各个外放模式的指向角度，通过配置的指向角度的声波进行声音信号传播，以使声音外放模式切换至对应的外放模式。
本实施例提供一种发声系统，该发声系统包括发声系统600是具有声场重建调节的发声系统，包括一个或多个发声单元601；在发声单元为多个的情况下，以阵列形式或者分布形式进行分布。
如图6 所示，发声系统包括发声系统600是具有声场重建调节的发声系统，具体可以通过扬声器阵列（loudspeaker array）方式实现声场重建，即控制指向性的大或小，示例性地，对于第一外放模式，设置全指向性模式，对于第二外放模式，设置强指向性模式。具体来说，智能设备中可以内设多个微型扬声器，多个微型扬声器可分别或者同时设置在智能设备的上下两端或中部，可根据实际需求来进行设计；多个微型扬声器可形成阵列，通过控制阵列各微型扬声器的延时和相位关系，实现微型扬声器阵列指向性的调整。发声系统600包括一个或多个发声单元601。作为本实施例的优选，采用多个发声单元，以便在多个方向对发声单元的声音外放方向进行调节和控制，并且在发声单元为多个的情况下，以阵列形式或者分布形式进行分布。

具体地，本实施例的声音外放的模式切换装置700，如图7所示，包括：参数获取模块702，用于在预设的时间周期内，获取当前环境参数值；判定模块704，用于将所述当前环境参数值与预设的环境特征值进行比较，判断所述当前环境参数值对应的环境状态，所述环境状态包括第一环境和第二环境；第一切换模块706，用于若所述环境状态为所述第一环境，将所述发声系统的声音外放的模式设置为所述第一外放模式；第二切换模块708，用于若所述环境状态为所述第二环境，将所述发声系统的声音外放的模式设置为所述第二外放模式。通过对声音外放模式的自动实时切换，提高了声音外放模式切换的便捷性，避免了用户手动切换不及时，或者手动随意切换声音外放模式造成的隐私风险。使得用户能够在不打扰周围人的情况下，能够欣赏声音外放，并且保护了用户的隐私，提升了用户体验。
需要说明的是，本实施例中声音外放的模式切换的装置的实现与上述声音外放的模式切换的方法的实现思想一致，其实现原理在此不再进行赘述，可具体参阅上述方法中对应内容。
