附图说明
为了更清楚地说明本申请实施例，下面将对实施例中所需要使用的附图做简单的介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据 这些附图获得其他的附图。

具体实施方式
本申请的核心是提供一种耳机的连接设备切换方法、系统、装置及耳机设备，能够实现在同一时刻两只耳机分别播放两个连接设备的音频信号，扩大了耳机的适用范围，增强用户体验。
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
首先需要说明的是，耳机设备包括两个耳机，分别为左耳机或右耳机，两个耳机均可以与多个连接设备配对，为便于理解，以两个连接设备分别为电脑和手机为例对本申请的方案进行说明。在执行本方案之前，首先完成左耳机与电脑和手机的配对，以及右耳机与电脑和手机的配对，以便左、右耳机均可以选择接收手机和/或电脑的音频信号。
可以理解的是，耳机设备在不同的应用环境中可选择不同的佩戴类别，如在一些应用环境中，左、右耳机可由同一用户佩戴，在另一些应用环境中，左、右耳机可分别由两个用户佩戴，考虑到耳机设备在不同的佩戴类别下，左、右耳机对于其各自要接收哪一个连接设备的音频信号会有不同的选择。
具体的，本实施例的方案的执行主体可以为耳机设备中的任一从充电仓中取出并佩戴的耳机，下文均以左耳机为例对本申请的控制逻辑进行说明，右耳机的控制逻辑，同理。
下面对本申请所提供的耳机的连接设备切换方法进行详细说明。
请参照图1，图1为本申请所提供的一种耳机的连接设备切换方法的步骤 流程图，该耳机的连接设备切换方法包括：
S101：确定耳机设备的佩戴类别，佩戴类别为同一用户佩戴或不同用户佩戴；
具体的，首先确定耳机设备的佩戴类别，即确定本机与右耳机是由同一用户佩戴，还是由两个用户分别佩戴，其中，同一用户佩戴中还包括，一个用户仅佩戴本机而右耳机仍在充电仓中未取出的情况，即单机佩戴。
本实施例中，可以按预设周期确定耳机设备的佩戴类别，以便及时发现耳机设备的佩戴类别的变化，并做出响应。
可以理解的是，假设本机与右耳机均从充电仓中取出，本机和右耳机的取出时间会存在先后顺序，可由先取出的耳机对耳机设备的佩戴类别进行检测。举例说明，假设本机先从充电仓中取出佩戴，本机可以每隔预设时间检测一次耳机设备的佩戴类别，并将该检测结果发送给正常佩戴的右耳机，以便右耳机根据本机的检测结果确定耳机设备的佩戴类别。相应的，假设右耳机先从充电仓中取出佩戴，则可由右耳机每隔预设时间检测一次耳机设备的佩戴类别，本机佩戴后可根据右耳机发送的检测结果确定耳机设备的佩戴类别。
进一步的，可预先选择耳机设备中的任意一个耳机作为主控耳机，另一耳机作为从控耳机。本机佩戴后，当检测到本机为主控耳机，本机可以每隔预设时间检测一次耳机设备的佩戴类别，并将检测结果发送给正常佩戴的从控耳机，以使从控耳机根据本机的检测结果确定耳机设备的佩戴类别，本机佩戴后，当检测到本机为从控耳机，本机可根据接收到的主控耳机发送的检测结果确定耳机设备的佩戴类别。考虑到可能存在从控耳机先于主控耳机从充电仓中取出的情况，若从控耳机从佩戴时刻起的预设时间段内，未接收到主控耳机发送的佩戴类别检测结果，则本机确定耳机设备的佩戴类别为单机佩戴，若后续接收到主控耳机发送的佩戴类别检测结果，再按该佩戴类别检测结果确定耳机设备的佩戴类别。
由一个耳机完成佩戴类别的判定，可以保证两个耳机是采用相同的佩戴类别检测结果进行后续的控制，以便后续准确选择各自对应的目标连接设备。
当然，也可由两个耳机各自分别对耳机设备的佩戴类别进行检测，即本机从充电仓取出并佩戴后，检测耳机设备的佩戴类别，右耳机从充电仓中取 出佩戴后，检测耳机设备的佩戴类别，两个耳机分别根据各自的检测得到的佩戴类别，选择各自对应的目标连接设备。
S102：根据佩戴类别在多个连接设备中选择本机的目标连接设备；
S103：接收并播放目标连接设备的音频信号。
在耳机设备的实际使用过程中，每一只耳机在同一时刻仅能播放一个连接设备的音频信号。因此，需要根据耳机设备的佩戴类别在所有连接设备中选择一个连接设备作为本机的目标连接设备，本机仅接收并播放目标连接设备的音频信号，本机不接收其他配对的连接设备的音频信号。
参照上文所述，佩戴类别包括同一用户佩戴或不同用户佩戴，在本申请中，当耳机设备中的两只耳机都从充电仓取出时，同一用户佩戴，即本机和右耳机由一个用户佩戴，不同用户佩戴，即本机由有一个用户佩戴，而右耳机由另一个用户佩戴，当耳机设备中只有本机从充电仓取出时，同一用户佩戴类别中还包括单机佩戴。
可以理解的是，本机与右耳机之间存在通信连接，可以进行数据交互，因此，二者可传输各自选择的目标连接设备的信息。
作为一种可选的实施例，根据佩戴类别在多个连接设备中选择本机的目标连接设备的过程包括：
当佩戴类别为同一用户佩戴，在多个连接设备中选择另一耳机的目标连接设备作为本机的目标连接设备；
当佩戴类别为多个用户佩戴，在多个连接设备中选择与另一耳机的目标连接设备不同的连接设备作为本机的目标连接设备。
具体的，若佩戴类别对应本机和右耳机由一个用户佩戴，那么本机选择的目标连接设备，与右耳机选择的目标连接设备相同，本机与右耳机均接收同一个目标连接设备的音频信号并输出，此时可以实现较高的立体声听觉体验。
若佩戴类别对应本机和右耳机分别由两个用户佩戴，那么本机选择的目标连接设备，与右耳机选择的目标连接设备可以不同。假设本机由用户A佩戴，右耳机由用户B佩戴，若本机选择电脑作为目标连接设备，接收并播放电脑的音频信号，相应的，右耳机选择手机作为目标连接设备，接收并播放耳机的音频信号，从而达到在同一时刻两只耳机分别播放不同连接设备的音 频信号的目的。当然，在某些应用环境下，如当用户A和用户B通过一台电脑看电影时，此时，本机和右耳机均可选择电脑作为目标连接设备，使本机和右耳机均接收并播放电脑的连接信号。
若佩戴类别为单机佩戴，即只有本机被取出佩戴，而右耳机在充电仓中未取出时，本机可根据各连接设备的音频信号播放顺序、各连接设备的播放优先级等信息选择目标连接设备。举例说明，当本机从充电仓中取出并佩戴后，若手机先输出音频信号，则将手机作为本机的目标连接设备；若手机和电脑均输出音频信号，则可根据预设的手机和电脑的播放优先级，选择播放优先级较高的连接设备作为本机的目标连接设备；若手机和电脑均输出音频信号，当本机从充电仓被取出后，手机和电脑均会暂停音频信号的输出，由用户选择某一设备继续播放，被选择的设备即为本机的目标连接设备。
可见，本实施例中，首先判断耳机设备的佩戴类别，即耳机设备中的两只耳机是由同一用户佩戴，还是由不同用户佩戴，然后两只耳机分别根据耳机设备的佩戴类别选择其各自对应的目标连接设备，两只耳机均仅接收并播放播放其各自对应的目标连接设备的音频信号，而不播放其他连接设备的音频信号，从而实现在同一时刻两只耳机分别播放两个连接设备的音频信号，扩大了耳机的适用范围，增强用户体验。
在上述实施例的基础上：
作为一种可选的实施例，确定耳机设备的佩戴类别的过程包括：
获取本机的第一惯性参数；
获取耳机设备中的另一耳机的第二惯性参数；
当第一惯性参数和第二惯性参数方向相同或方向相反，判定耳机设备的佩戴类别为同一用户佩戴，否则，判定耳机设备的佩戴类别为不同用户佩戴。
作为一种可选的实施例，获取本机的第一惯性参数的过程包括：
当检测到本机为佩戴状态，获取本机的第一惯性参数；
获取耳机设备中的另一耳机的第二惯性参数的过程包括：
当检测到耳机设备中的另一耳机为佩戴状态，获取另一耳机的第二惯性参数。
具体的，耳机设备中每一耳机内部均包括惯性传感器和接近传感器，其 中接近传感器用于执行耳机的佩戴检测，惯性传感器在判定耳机正常佩戴后获取耳机的惯性参数，两个耳机可通过无线传输各自的惯性参数。以左耳机为例对佩戴类别的检测过程进行说明，当左耳机从充电仓被取出后，左耳机内部的接近传感器工作，检测左耳机是否被用户佩戴，若是，左耳机的惯性传感器工作，获取左耳机的第一惯性参数，当左耳机获取到右耳机的第二惯性参数后，比对第一惯性参数和第二惯性参数，当第一惯性参数和第二惯性参数方向相同或方向相反，判定耳机设备的佩戴类别为同一用户佩戴，否则，判定耳机设备的佩戴类别为不同用户佩戴，右耳机的佩戴类别的检测过程，同理。
当然，上述实施例是两个耳机均进行佩戴类别检测的方案，作为另一种可选的实施例，还可以根据两只耳机从充电仓中取出的先后顺序，由先取出的耳机进行佩戴类别的检测，假设先取出的耳机为左耳机，左耳机正常佩戴后，通过惯性传感器获取自身的惯性参数，当右耳机取出佩戴后，由惯性传感器获取其自身的惯性参数后，将该惯性参数发送给左耳机，左耳机将自身的惯性参数和右耳机发送的惯性参数进行比对得到耳机设备的佩戴类别，并将佩戴类别发送给右耳机，在本实施例中，右耳机无需获取左耳机的惯性参数执行比对、佩戴类别判定等操作。
下面对如何根据左、右耳机的惯性参数确定耳机设备的佩戴类别进行举例说明：首先定义惯性传感器的六个轴，三轴加速度分别为a x，a y，a z，三轴角加速度分别为a rx，a ry，a rz，六轴加速度计示意图参照图2所示。左耳机或右耳机从充电仓取出后，左耳机和右耳机都会通过接近传感器进行佩戴检测，当检测到左耳机佩戴后，左耳机的惯性传感器开始工作并采集六轴参数，即a 1x，a 1y，a 1z，a 1rx，a 1ry，a 1rz，当右耳机的接近传感器检测到右耳机正常佩戴后，右耳机的惯性传感器开始工作并采集六轴参数，即a 2x，a 2y，a 2z，a 2rx，a 2ry，a 2rz。
当左、右耳机被同一用户佩戴时，无论用户头部进行什么动作，左、右耳机的相对位置是不变的，运动方向可以确定，加速度方向会在同一直线上，要么同向，要么反向，首先判断三轴的加速度，三轴的加速度合成矢量大小会不同，但是方向一定是同向或者反向，因此，判断合成矢量的方向，
Figure PCTCN2021122225-appb-000001
与
Figure PCTCN2021122225-appb-000002
的方向相同或相反，不进行数值大小的匹配，三轴角 加速度的方向一定相同，即a 1rx与a 2rx方向相同，a 1ry与a 2ry方向相同，a 1rz与a 2rz方向相同。左、右耳机的惯性传感器均按预设周期(如6ms)采集六轴参数，当连续多个周期(如300ms)采集到六轴参数均满足上述条件，则判定佩戴类别为同一用户佩戴。进一步的，如果中间有少许采样数据不满足条件，则舍弃，并增加数据进行匹配以确保准确性。
当左、右耳机分别被不同用户佩戴时，两个用户的运动状况会不同，此时合成的矢量方向
Figure PCTCN2021122225-appb-000003
与
Figure PCTCN2021122225-appb-000004
不在一条直线(方向不相同也不相反)，角加速度a 1rx与a 2rx方向可能不同，a 1ry与a 2ry方向，a 1rz与a 2rz方向可能会不同，如果连续多个周期(如300ms)采集到六轴参数，只要每次都能够满足以上四点中的一点，则判定佩戴类别为不同用户佩戴。进一步的，如果中间有少许数据不满足上述条件，则舍弃并增加数据匹配以确保准确性。可以理解的是，惯性传感器的精度较高，能够较为准确地识别出两个用户佩戴时的运动状况的不同。
作为一种可选的实施例，确定耳机设备的佩戴类别的过程包括：
获取本机和耳机设备中另一耳机之间的距离；
当距离小于第一预设值，耳机设备的佩戴类别为同一用户佩戴；
当距离大于第二预设值，耳机设备的佩戴类别为不同用户佩戴；
第二预设值大于或等于第一预设值。作为一种可选的实施例，获取本机和耳机设备中另一耳机之间的距离的过程包括：
通过RSSI测量本机和耳机设备中另一耳机之间的距离。
可以理解的是，目前耳机设备中的两个耳机均通过蓝牙进行通信，因此，可通过蓝牙RSSI测距原理来判断两个耳机之间距离。具体的，蓝牙RSSI测距原理是通过蓝牙信号强度和收发设备距离建立相关的关系式，从而通过RSSI值计算出两个蓝牙设备(即本申请中的左耳机和右耳机)间的距离。关系式为：
d＝10 (A-txpower)/10n；
其中，d为左耳机和右耳机之间的距离，n为经验值，在工厂端进行校准测算，txpower为当前设备距离1m时的RSSI值，A为当前获取的RSSI值。D和A值近似的成正比的关系。在出厂前对每对耳机进行RSSI校准，固定n值和txpower值。然后使用仿真头(50-65cm)进行校准，获取真实佩戴情况 下，正常人佩戴的RSSI值，存储到flash中。
在用户进行佩戴时，进行A值的检测，如果在flash存储的区间内，则说明为佩戴类别为同一用户佩戴，可语音提示单人佩戴，如果此时实际为两人佩戴，则两位用户位置疏远一些，则可重新判断为不同用户佩戴，并且停止进行佩戴类别的检测，直到检测出有人摘下耳机的动作后，再重新进行佩戴类别的检测，相应的，如果佩戴后检测到的A值不在区间内，则直接判断为不同用户佩戴。
作为一种可选的实施例，根据佩戴类别在多个连接设备中选择本机的目标连接设备的过程包括：
获取本机与另一耳机的佩戴先后顺序；
根据佩戴先后顺序及佩戴类别，在多个连接设备中选择本机的目标连接设备。
具体的，假设左耳机先从充电仓中取出，当左耳机取出并被佩戴后，从电脑或手机中选择一个连接设备作为左耳机的目标连接设备，假设目标连接设备为手机，则令手机输出音频信号，保证左耳机与手机进行匹配，接收手机输出的音频信号，然后当右耳机从充电仓中取出佩戴后，进行佩戴类别的检测，如果是同一用户佩戴，右耳机也选择耳机作为目标连接设备，接收并播放手机输出的音频信号，若果是不同用户佩戴，右耳机选择电脑作为目标连接设备，接收并播放电脑输出的音频信号。
请参照图3，图3为本申请所提供的一种耳机的连接设备切换系统的结构示意图，应用于耳机设备中的任一耳机，该连接设备切换系统包括：
确定模块11，用于确定耳机设备的佩戴类别，佩戴类别为同一用户佩戴或不同用户佩戴；
选择模块12，用于根据佩戴类别在多个连接设备中选择本机的目标连接设备；
控制模块13，用于接收并播放目标连接设备的音频信号。
可见，本实施例中，首先判断耳机设备的佩戴类别，即耳机设备中的两只耳机是由同一用户佩戴，还是由不同用户佩戴，然后两只耳机分别根据耳机设备的佩戴类别选择其各自对应的目标连接设备，两只耳机均仅接收并播 放播放其各自对应的目标连接设备的音频信号，而不播放其他连接设备的音频信号，从而实现在同一时刻两只耳机分别播放两个连接设备的音频信号，扩大了耳机的适用范围，增强用户体验。

作为一种可选的实施例，根据佩戴类别在多个连接设备中选择本机的目标连接设备的过程包括：
