Description

蓝牙音箱的控制方法及系统、存储介质及移动终端
本申请要求于2020年09月04日提交中国专利局、申请号为202010924318.4、发明名称为“蓝牙音箱的控制方法及系统、存储介质及移动终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及计算机技术，尤其涉及一种蓝牙音箱的控制方法及系统、存储介质及移动终端。
 背景技术
目前家庭剧院的概念在一般人的印象中代表昂贵、需要布线、沉重，至少需要播放器（一般为DVD机）、功放、5.1声道音响及大量的线。
随着控制终端和无线传输技术的发展，无线音箱正变得越来越普及，使得任意房间都能成为随心所欲享受音乐的场所。在由无线音箱组成的无线音乐系统中，一般由多个无线音箱组成。这些音箱可以放置在家中的多个地方，如有的放置在客厅，有的放置在卧室，有的放置在书房等等。这些无线音箱可通过无线传输技术实现相互连接通信。
目前，如果通过移动终端控制无线音箱的数量受到限制，仅为一台。因此无法使得用户能够享受到多个音箱（例如4个音箱）所具有的多声道音响效果。
此外，由于音频信号在无线传输过程中需要编码、解码，而音频信号编码、解码的过程均需要一定的时间，因此在播放相应的音频信号时，会出现音频信号延迟的现象，影响用户的听觉效果和体验。
 技术问题
本申请实施例提供一种蓝牙音箱的控制方法及系统、存储介质及移动终端，不仅有效解决了移动终端不能同时连接多个音箱，而且还解决了通过蓝牙连接多个音箱，存在音频播放延迟的问题。

 本发明的实施方式
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，所描述的实施例仅仅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，都属于本申请保护的范围。
如图1所示，为本申请一实施例提供的蓝牙音箱的控制方法的步骤流程图。所述蓝牙音箱的控制方法适用于一移动终端，该控制方法包括步骤：
步骤S110：获取一音频信息。
在本申请实施例中，所述音频信息是指自然界中各种音源发出的可闻声和由计算机通过专门设备合成的语音或音乐。
步骤S120：对所述音频信息进行解析。
在本申请实施例中，当播放音视频源时，会调用移动终端（例如安卓手机）的系统架构层中的媒体解码器，对所述音频信息解码。
步骤S130：通过所述移动终端系统框架中的音频管理器构建多个声道。
在本申请所述实施例中，所述声道是指声音在录制或播放时在不同空间位置采集或回放的相互独立的音频信号，因此所述声道的数量也就是声音录制时的音源数量或回放时相应的扬声器数量。具体的，例如，将获得的立体声通过音频管理器的上混模块的上混音算法处理，并经过延时模块、低通滤波模块及移相模块输出以形成四声道。又例如，将获得的5.1声道通过音频管理器的下混模块上混音算法处理后形成相应的四声道。
步骤S140：通过所述移动终端的蓝牙协议栈构建多个虚拟蓝牙音频传输模型协议通道。
在本申请所述实施例中，通过蓝牙协议栈构能够使各个蓝牙设备之间进行射频连接。蓝牙音频传输模型协议(Advanced Audio Distribution Profile，简称A2DP)是蓝牙的音频传输协议，应用于蓝牙设备，定义了蓝牙设备之间数据流句柄的参数协商，建立和传输过程以及相互交换的信令实体形式。因此，通过蓝牙协议栈能够虚拟出多个采用蓝牙音频传输模型协议的通道。
步骤S150：将所述多个虚拟蓝牙音频传输模型协议通道与外部的多个蓝牙音箱对应连接。
在本申请所述实施例中，所述蓝牙音箱内置蓝牙芯片，以蓝牙连接取代线材连接。因此，通过步骤S140和步骤S150的实施，能够实现移动终端的蓝牙协议栈通过蓝牙协议与多个蓝牙音箱相对应的连接。
步骤S160：将解析后的所述音频信息发送到所述音频管理器中的所述多个声道中。
在本实施例中，所述解析后的所述音频信息包括四个声道，于是可以通过蓝牙协议栈虚拟出四个A2DP协议通道分别与四个蓝牙音箱相对应的连接。当然在其他部分实施中，所述音频信息也可以包括三个声道、五个声道、或多个声道的，于是也可以通过蓝牙协议栈虚拟出相应数量的A2DP协议通道与外部的多个蓝牙音箱对应连接。进一步，可以采用分时多工的方式，分别传输其对应协议通道的音频信息。
步骤S170：对所述多个蓝牙音箱进行同步检测。
在本实施例中，对所述多个蓝牙音箱进行同步检测，以避免多个蓝牙音箱的音频信号发生延迟的现象。具体操作包括如下步骤：
结合参阅图2。
步骤S171：获取所述多个蓝牙音箱的延迟时间。
在此步骤中，可以分别对每个蓝牙音箱进行播放音频的测试，并用手机麦克风采集该声音，从而得到相应蓝牙音箱的延迟时间。
步骤S172：根据所获得的所述多个蓝牙音箱的延迟时间以判断出最长的延迟时间。
由于多个蓝牙音箱的延迟时间不同，因此，需要判断出最长的延迟时间。在本实例中，所述蓝牙音箱的数量为四个，因此，需要分别对四个蓝牙音箱进行播放音频的测试以及获取相应蓝牙音箱的延迟时间。
步骤S173：将最长的延迟时间配置为音频播放的延迟时间。
在此步骤中，通过将最长的延迟时间配置为音频播放的延迟时间，可以避免多个蓝牙音箱的音频信号发生延迟的现象。
继续参阅图1，步骤S180：将所述多个声道中的所述音频信息通过所述多个蓝牙音箱进行播放。
在此步骤中，通过将多个声道（例如四声道）中的所述音频信息传送至相应的蓝牙音箱，并进行播放。
本申请所述方法通过上述步骤S110至步骤S180的实施能够实现一个移动终端控制多个蓝牙音箱。此外，所述方法对所述多个蓝牙音箱进行同步检测，以避免多个蓝牙音箱的音频信号发生延迟的现象。
本申请的优点在于，相较于现有技术，本申请所述方法通过所述移动终端系统框架中的音频管理器构建多个声道，再通过所述移动终端的蓝牙协议栈构建多个虚拟蓝牙音频传输模型协议通道，将所述多个虚拟蓝牙音频传输模型协议通道与外部的多个蓝牙音箱对应连接，使所述多个声道中的所述音频信息通过所述多个蓝牙音箱进行播放。另外所述方法对所述多个蓝牙音箱进行同步检测，以避免多个蓝牙音箱的音频信号发生延迟的现象。
如图3所示，为本申请实施例提供的蓝牙音箱的控制系统结构示意图，包括：一音频获取单元1、一音频解析单元2、一声道构建单元3、一蓝牙协议构建单元4、一连接单元5、一音频信息发送单元6、一音频信息播放单元8及一同步检测单元7。

所述音频解析单元2用于对所述音频信息进行解析。在本申请实施例中，当播放音视频源时，会调用移动终端（例如安卓手机）的系统架构层中的媒体解码器，对所述音频信息解码。
所述声道构建单元3用于通过所述移动终端系统框架中的音频管理器构建多个声道。在本申请所述实施例中，所述声道是指声音在录制或播放时在不同空间位置采集或回放的相互独立的音频信号，因此所述声道的数量也就是声音录制时的音源数量或回放时相应的扬声器数量。
所述蓝牙协议构建单元4用于通过所述移动终端的蓝牙协议栈构建多个虚拟蓝牙音频传输模型协议通道。在本申请所述实施例中，通过蓝牙协议栈构能够使各个蓝牙设备之间进行射频连接。蓝牙音频传输模型协议(Advanced Audio Distribution Profile，简称A2DP)是蓝牙的音频传输协议，应用于蓝牙设备，定义了蓝牙设备之间数据流句柄的参数协商，建立和传输过程以及相互交换的信令实体形式。因此，通过蓝牙协议栈能够虚拟出多个采用蓝牙音频传输模型协议的通道。
所述连接单元5用于将所述多个虚拟蓝牙音频传输模型协议通道与外部的多个蓝牙音箱对应连接。在本实施例中，所述蓝牙音箱内置蓝牙芯片，以蓝牙连接取代线材连接。因此，通过调用蓝牙协议构建单元4和连接单元5，能够实现移动终端的蓝牙协议栈通过蓝牙协议与多个蓝牙音箱相对应的连接。
所述音频信息发送单元6用于将解析后的所述音频信息发送到所述音频管理器中的所述多个声道中。在本申请实施例中，所述解析后的所述音频信息包括四个声道，于是可以通过蓝牙协议栈虚拟出四个A2DP协议通道分别与四个蓝牙音箱相对应的连接。当然在其他部分实施中，所述音频信息也可以包括三个声道、五个声道、或多个声道的，于是也可以通过蓝牙协议栈虚拟出相应数量的A2DP协议通道与外部的多个蓝牙音箱对应连接。进一步，可以采用分时多工的方式，分别传输其对应协议通道的音频信息。
所述同步检测单元7用于对所述多个蓝牙音箱进行同步检测。所述同步检测单元7包括：一延迟获取单元9、一延迟时间判断单元10及一延时时间配置单元11。
所述延迟获取单元9用于获取所述多个蓝牙音箱的延迟时间。具体地，可以分别对每个蓝牙音箱进行播放音频的测试，并用手机麦克风采集该声音，从而得到相应蓝牙音箱的延迟时间。
所述延迟时间判断单元10用于根据所获得的所述多个蓝牙音箱的延迟时间以判断出最长的延迟时间。由于多个蓝牙音箱的延迟时间不同，因此，需要判断出最长的延迟时间。在本实例中，所述蓝牙音箱的数量为四个，因此，需要分别对四个蓝牙音箱进行播放音频的测试以及获取相应蓝牙音箱的延迟时间。
所述延时时间配置单元11用于将最长的延迟时间配置为音频播放的延迟时间。在本申请实施例中，通过将最长的延迟时间配置为音频播放的延迟时间，可以避免多个蓝牙音箱的音频信号发生延迟的现象。
所述音频信息播放单元8用于将所述多个声道中的所述音频信息通过所述多个蓝牙音箱进行播放。通过将多个声道（例如四声道）中的所述音频信息传送至相应的蓝牙音箱，并进行播放。
因此，本申请所述系统通过所述移动终端系统框架中的音频管理器构建多个声道，再通过所述移动终端的蓝牙协议栈构建多个虚拟蓝牙音频传输模型协议通道，将所述多个虚拟蓝牙音频传输模型协议通道与外部的多个蓝牙音箱对应连接，使所述多个声道中的所述音频信息通过所述多个蓝牙音箱进行播放，从而能够实现一个移动终端控制多个蓝牙音箱。
