请参考图5，图5为本发明实施例所提供的一种无线播放设备的播放控制方法的流程图。该方法可以包括：
步骤101：获取无线播放设备与头带设备的连接情况；其中，连接情况包括连接状态和未连接状态。
其中，本步骤的目的可以为无线播放设备中如蓝牙芯片的处理器，通过获取无线播放设备与头带设备的连接情况，确定无线播放设备能够与头带设备可拆卸连接的外壳是否与头带设备处于连接状态，即确定无线播放设备是否与头带设备组成类似传统头戴式耳机的产品形态。
需要说明的是，对于本步骤中处理器获取无线播放设备与头带设备的连接情况的具体方式，可以由设计人员根据实用场景和用户需求自行设置，如头带设备具有充电功能时，为了保证充电的稳定性，若头带设备中用于为无线播放设备供电的连接器与无线播放设备对应的连接器连接，则无线播放设备的外壳必定与头带设备连接，因此，本步骤中处理器可以直接根据头带设备与无线播放设备的供电连接情况，获取无线播放设备与头带设备的连接情况；为了保证获取的连接情况的准确性和实时性，可以在无线播放设备的外壳上与头带设备连接的相应位置设置头带检测设备，以使处理器可以根据头带检测设备采集到的连接情况数据，确定无线播放设备的外壳与头带设备的连接情况，即本步骤中处理器也可以根据设置在的无线播放设备上的头带检测设备，获取无线播放设备与头带设备的连接情况。只要处理器可以获取无线播放设备与头带设备的连接情况，本实施例对此不做任何限制。
步骤102：根据连接情况，控制PA运放设备，调节扬声器工作的功率模式；其中，PA运放设备和扬声器均设置在无线播放设备上。
可以理解的是，本步骤的目的可以为处理器根据无线播放设备与头带设备的连接情况，通过控制无线播放设备上的PA运放设备，调节无线播放设备上的扬声器工作的功率模式，以保证扬声器工作的功率模式与用户的使用需求相对应。
对应的，对于本步骤中处理器根据连接情况，控制PA运放设备，调节扬声器工作的功率模式的具体方式，可以由设计人员根据实用场景和用户需求自行设置，可以仅利用无线播放设备与头带设备的连接情况，确定用户的使用需求，如连接情况为连接状态时，可以确定用户需要使用无线播放设备的耳机功能，处理器可以控制PA运放设备，使扬声器工作在高功率模式；连接情况为未连接状态时，可以确定用户需要使用无线播放设备的小型音箱功能，处理器可以控制PA运放设备，使扬声器工作在高功率模式。也可以利用无线播放设备与头带设备的连接情况和无线播放设备的佩戴情况，确定用户的使用需求，即处理器可以根据连接情况和获取的无线播放设备的佩戴情况，控制PA运放设备，调节扬声器工作的功率模式；还可以利用无线播放设备与头带设备的连接情况和无线播放设备与其它无线播放设备的配对连接情况，确定用户的使用需求，即处理器可以根据连接情况和获取的无线播放设备与其它无线播放设备的配对连接情况，控制PA运放设备，调节扬声器工作的功率模式。本实施例对此不做任何限制。
具体的，对于本步骤中PA运放设备的具体结构和类型，可以由设计人员根据实用场景和用户需求自行设置，只要PA运放设备可以根据处理器的控制，调节所连接的扬声器工作的功率模式，改变扬声器播放音频的声压级，本实施例对此不做任何限制。
需要说明的是，本步骤中处理器不仅可以根据连接情况，控制PA运放设备，调节扬声器工作的功率模式，还可以根据连接情况，对应控制无线播放设备上的主动降噪设备的启动和关闭，如处理器控制PA运放设备，使扬声器工作在低功率模式之后，还可以控制主动降噪设备，对扬声器播放的音频进行主动降噪，即实现无线播放设备的耳机主动降噪功能；对应的，处理器控制PA运放设备，使扬声器工作在高功率模式之后，还控制主动降噪设备，停止对扬声器播放的音频进行主动降噪，即在实现无线播放设备的小型音箱功能时，关闭主动降噪。
本实施例中，本发明实施例通过根据无线播放设备与头带设备的连接情况，控制PA运放设备，调节扬声器工作的功率模式，可以实现无线播放设备的耳机功能和小型音箱功能的自动切换，提升了用户体验。

可以理解的是，本步骤的目的可以为处理器利用设置在的无线播放设备上的头带检测设备采集的连接情况数据，确定无线播放设备与头带设备的连接情况。具体的，对于上述 连接情况数据的具体类型，即头带检测设备的具体类型，可以由设计人员根据实用场景和用户需求自行设置，如头带检测设备可以为设置在无线播放设备的外壳上的头带插孔底部的图3所示的中断检测电路时，连接情况数据可以为处理器的信号输入端检测到的电压信号，即本步骤可以为处理器判断是否接收到中断检测电路发送的中断信号(GPIO中断，电压为零)；其中，头带设备与无线播放设备连接时，中断检测电路发送中断信号；若是，则确定连接情况为连接状态；若否，则确定连接情况为未连接状态。头带检测设备也可以为设置在无线播放设备的外壳上的头带插孔底部的如红外传感器的距离传感器，连接情况数据可以为距离传感器发送的距离数据，即本步骤可以为处理器判断接收的距离传感器发送的距离数据对应的距离值是否小于阈值；若是，则确定连接情况为连接状态；若否，则确定连接情况为未连接状态。本实施例对此不做任何限制。
步骤202：获取无线播放设备的佩戴情况；其中，佩戴情况包括佩戴状态和未佩戴状态。
其中，本步骤中的目的可以为处理器通过获取无线播放设备的佩戴情况，确定用户是否将无线播放设备放置或佩戴在耳边使用。即佩戴情况为佩戴状态时，可以确定用户正将无线播放设备放置或佩戴在耳边使用，如用户手持无线播放设备到耳边的状态、佩戴带有耳挂部件的无线播放设备的状态或佩戴外壳连接头带设备的无线播放设备的状态；佩戴情况为未佩戴状态时，未将无线播放设备放置或佩戴在耳边使用。
具体的，对于本步骤中处理器获取无线播放设备的佩戴情况的具体方式，可以采用与现有入耳式或半入耳式TWS蓝牙耳机的佩戴检测相同或相似的方式实现，如可以根据无线播放设备上设置的如距离传感器和/或加速度传感器，获取无线播放设备的佩戴情况。本实施例对此不做任何限制。
可以理解的是，本步骤与步骤201并不存在逻辑上的先后顺序，可以如本实施例所示先进行步骤201再进行本步骤，也可以将本步骤与步骤201调换顺序，还可以同时进行本步骤和步骤201，本实施例对此不做任何限制。
步骤203：根据连接情况和佩戴情况，控制PA运放设备，调节扬声器工作的功率模式。
可以理解的是，本步骤的目的可以为处理器根据无线播放设备与头带设备的连接情况和无线播放设备的佩戴情况，通过控制无线播放设备上的PA运放设备，调节无线播放设备上的扬声器工作的功率模式，以保证扬声器工作的功率模式与用户的使用需求相对应。
对应的，对于本步骤中处理器根据连接情况和佩戴情况，控制PA运放设备，调节扬声器工作的功率模式的具体过程，可以由设计人员根据实用场景和用户需求自行设置，如可以处理器分别判断无线播放设备与头带设备的连接情况是否为连接状态和无线播放设备的佩戴情况是否为佩戴状态，在佩戴情况为佩戴状态时，确定用户需要使用无线播放设备的耳机功能，可以控制PA运放设备，使扬声器工作在低功率模式；在佩戴情况不为佩戴状态且连接情况不为连接状态时，确定用户需要使用无线播放设备的小型音箱功能，可以控制PA运放设备，使扬声器工作在高功率模式。本实施例对此不做任何限制。
对应的，对于上述判断中的佩戴情况不为佩戴状态且连接情况为连接状态的情况，可以处理器可以控制PA运放设备，使扬声器工作在低功率模式或高功率模式；也可以停止扬声器的音频播放，并进入待机状态。本实施例对此不做任何限制。
进一步的，上述处理器控制PA运放设备，使扬声器工作在低功率模式之后，还可以控制主动降噪设备，对扬声器播放的音频进行主动降噪，即实现无线播放设备的耳机主动降噪功能；对应的，处理器控制PA运放设备，使扬声器工作在高功率模式之后，还控制主动降噪设备，停止对扬声器播放的音频进行主动降噪，即在实现无线播放设备的小型音箱功能时，关闭主动降噪。
进一步的，上述处理器控制PA运放设备，使扬声器工作在高功率模式之前，还可以判断佩戴情况是否在预设时间段内均不为佩戴状态；若是，则控制PA运放设备，使扬声器工作在高功率模式；若否，则使扬声器工作维持在当前的模式。避免佩戴检测的误判情况可能对用户耳朵造成的伤害。
本实施例中，本发明实施例通过根据连接情况和佩戴情况，控制PA运放设备，调节扬声器工作的功率模式，进一步提高了无线播放设备的耳机功能和小型音箱功能之间切换的准确性，提升了用户体验。
