然而，由于该类广播中大部分时刻都为静音包，只在需要的时候才会进行音频播放(如提示登机、报站点以及火警等)，因此，为了能够及时收听广播信号，耳机、音响等音频输出设备需要持续不间断的进行广播收听，从而导致了耳机电量损耗过大的缺陷；并且如果音频输出设备当前正在播放其他音频数据，会使广播音频数据的播放与其他音频数据的播放产生时序冲突的问题。

具体实施方式
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。可以理解的是，此处所描述的具体实施例仅用于解释相关申请，而非对该申请的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与有关申请相关的部分。
随着通信技术的快速发展，通信环境中涉及有很多BIS/BIG，例如地铁中报站器、警报器、家中的门铃、机场登机播报或者火车站的登车播报。目前，SIG组织定义的该类协议广播均通过耳机/音响去进行收听。手机作为辅助方把广播的配置信息，如每个广播设备对应的广播接收密码。
然而，由于该类广播中大部分时刻都为静音包，只在需要的时候才会进行音频播放(如提示登机、报站点以及火警等)，因此，如果这些广播按SIG的方案，都需要耳机自己去收听的话，由于没声音的时候也需要持续不间断的进行广播收听，否则声音来的时候无法及时收到，因而导致了耳机电量损耗过大的缺陷；而且如果当前耳机/音响播放 手机/TV的语音或者音乐，会存在广播音频数据播放与其他音频播放时序冲突的问题，即时间片的冲突会非常严重。鉴于此，如何高效的进行广播音频数据至用户的传输，成为一个亟待解决的技术问题。
为了解决上述问题，本申请实施例提供了一种音频传输方法及系统、芯片及存储介质。一方面不再需要音频输出设备，如耳机/音响自主的接收广播音频数据，而是通过音频中转设备来进行广播音频数据的采集，耳机/音响只需要连接并接收音频中转设备转发的音频数据即可，克服了耳机耗电量过大的缺陷；另一方面，音频传输系统在接收到广播音频数据之后，可以根据该广播音频数据和当前输出的其他音频数据生成待传输的目标音频数据，进而对该目标音频数据进行播放处理，解决了广播音频数据的播放与其他音频数据的播放存在时序冲突的问题，系统智能性高。
应理解，本发明实施例的技术方案本申请实施例的技术方案可以应用第五代移动通信网络(5th generation mobile networks，5G)通信系统或未来的通信系统，也可以用于其他各种无线通信系统，例如：全球移动通讯(GSM，Global System of Mobile Communication)系统、码分多址(CDMA，Code Division Multiple Access)系统、宽带码分多址(WCDMA，Wideband Code Division Multiple Access)系统、通用分组无线业务(GPRS，General Packet Radio Service)、长期演进(LTE，Long Term Evolution)系统、LTE频分双工(FDD，Frequency Division Duplex)系统、LTE时分双工(TDD，Time Division Duplex)、通用移动通信系统(UMTS，Universal Mobile Telecommunication System)等。
本申请一实施例提供了一种音频传输方法，应用于图1所示的音频传输系统，图1为本申请实施例提出的音频传输系统的组成结构示意图一，如图1所示，在本申请的实施例中，音频传输系统10包括音频中转设备20和音频输出设备30。
需要说明的是，在本申请的实施例中，图1所示的音频传输系统10可应用于图2所示的广播收听系统，可用于接收并播放来自于外界广播设备的广播音频数据。图2为本申请实施例提出的广播收听系统的结构示意图，如图2所示，在本申请的实施例中，广播收听系统40包括广播设备50以及音频传输系统10。
具体的，广播设备50用于进行广播音频数据的发送；音频中转设备20用于接收来自于广播设备50的广播音频数据，并转发至音频输出设备30；音频输出设备30用于对接收到的广播音频数据进行输出播放以使用户收听。
应理解，音频中转设备20可以是用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程音频中转设备、移动设备、用户音频中转设备、音频中转设备、无线通信设备、用户代理或用户装置，音频中转设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的音频中转设备或者未来演进的公共陆地移动网(Public Land Mobile Network，PLMN)中的音频中转设备等。
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。
本申请一实施例提供了一种音频传输方法，图3为本申请实施例提出的音频传输方法的实现流程示意图一，如图3所示，在本申请的实施例中，音频传输系统执行音频传输方法可以包括以下步骤：
步骤100、在音频中转设备与音频输出设备建立无线通信连接之后，音频中转设备获取目标广播音频数据。
在本申请的实施例中，音频传输系统可以在音频中转设备与音频输出设备建立无线通信连接之后，先通过音频中转设备获取目标广播音频数据。
需要说明的是，在本申请的实施例中，音频中转设备可以为任何具备音频采集传输功能的无线通信电子设备。可选的，该音频中转设备不局限于智能手机、网关设备(如路由器)、平板电脑、电视、个人计算机(Personal Computer，PC)、笔记本电脑等电子设备。
需要说明的是，在本申请的实施例中，音频输出设备可以为任何具备音频播放功能的无线通信电子设备。具体的，该无线通信可以为蓝牙通信。可选的，该音频输出设备不局限于蓝牙耳机、蓝牙音响。
可以理解的是，在本申请的实施例中，若要使用蓝牙耳机或者蓝牙音响对音频中转设备中的音频数据进行播放，音频中转设备可以为具备蓝牙通信功能的电子设备。这里，音频传输系统可以先建立音频中转设备与这些音频输出设备之间的蓝牙通信连接。
在本申请的一些实施例中，音频中转设备可以向音频输出设备发送蓝牙连接请求，并等待接收音频输出设备的配对连接确认信息，当接收到该音频设备返回的配对连接指令时，音频中转设备便可以基于该配对连接指令建立与音频传输设备之间的蓝牙通信连接。
需要说明的是，在本申请的实施例中，上述蓝牙通信连接不限定于传统的蓝牙物理链路(Asynchronous Connectionless，ACL)，也可以是BT5.2新引入的CIG/CIS链路。
进一步的，在本申请的实施例中，音频中转设备在与音频输出设备建立通信连接之后，音频中转设备便可以先获取广播音频数据。应理解，在本申请的实施例中，音频中转设备可以获取来自于广播设备的广播音频数据。
应理解，该广播设备可以为可进行BIG/BIS广播的设备，也可以为通过扬声器/喇叭播放广播的设备。例如地铁中报站器，警报器，家里的门铃，机场的登机或者火车站的登车播报器。
可以理解的是，在本申请的实施例中，为了保证广播的及时收听，音频中转设备始终需要保持在广播收听状态，然而在将接收到的广播音频数据通过音频输出设备进行输出播放的时候，有可能当前正在进行其他音频数据的输出播放，为了避免广播音频数据的播放与当前播放的其他音频数据产生时序冲突，音频中转设备需要在接收广播音频数据的同时，进行当前音频输出状态的实时检测。
进一步的，在本申请的实施例中，音频传输系统在通过音频中转设备获取目标广播音频数据，并检测出当前音频输出状态之后，音频中转设备可以进一步根据当前音频输出状态判断是否执行该广播音频数据的混音处理。
步骤110、若音频中转设备的当前状态为输出初始音频数据，则音频中转设备根据初始音频数据和目标广播音频数据生成待传输音频数据。
步骤120、音频中转设备将待传输音频数据发送至音频输出设备。
在本申请的实施例中，音频传输系统在通过音频中转设备获取到广播音频数据以及检测出当前音频输出状态之后，如果音频中转设备的当前状态为输出初始音频数据，那么音频中转设备便可以根据初始音频数据和目标广播音频数据先生成待传输音频数据。
需要说明的是，在本申请的实施例中，初始音频数据指音频中转设备当前正向音频输出设备发送的其他非广播音频数据。
需要说明的是，在本申请的实施例中，音频中转设备的当前状态可以是音频中转设备当前正向音频输出设备发送其他非广播音频数据，以通过音频输出设备进行其他非广播音频数据的播放；另一方面，音频中转设备的当前状态还可以是音频中转设备当前并未向音频输出设备发送任何音频数据，即当前音频输出设备并没有进行任何其他非广播 音频数据的播放。
这里，如果音频中转设备确定当前状态为输出初始音频数据，那么为了在不影响其他初始音频数据的播放，同时用户又可以及时收听到广播音频数据，音频中转设备可以基于对目标广播音频数据和初始音频数据的混音处理获得待传输音频数据，并将待传输数据发送至音频输出设备。
步骤130、音频输出设备播放待传输音频数据。
在本申请的实施例中，音频输出设备在接收到音频中转设备发送的待传输音频数据之后，便可对该待传输音频数据进行播放。
需要说明的是，在本申请的实施例中，音频输出设备针对不同的待传输音频数据采用不同的播放策略。
这里，当待传输数据为经混音处理得到的混音后音频数据时，音频输出设备以不同的音量对广播音频数据和初始音频数据进行播放。
在本申请的一些实施例中，图4为本申请实施例提出的音频传输方法的实现流程示意图二，如图4所示，在本申请的实施例中，音频中转设备根据初始音频数据和目标广播音频数据生成待传输音频数据可以包括以下步骤：
步骤111、若音频中转设备的当前状态为输出初始音频数据，音频中转设备对初始音频数据和目标广播音频数据进行混音处理，生成混音后音频数据；其中，混音后数据包括第一识别等级的目标广播音频数据和第二识别等级的初始音频数据；第一识别等级大于第二识别等级。
可以理解的是，由于混音处理是将多个音频数据同时播放，那么为了使用户更有效的收听到广播音频数据，音频中转设备需要使广播音频数据在音频输出设备播放时更为突出，因此，在本申请的实施例中，音频中转设备需要先对广播音频数据和初始音频数据这两个音频数据进行能够使目标广播音频数据在播放时突出于初始音频数据的混音操作，也就是说，使混音后数据中的目标广播音频数据相比于初始音频数据更容易被用户识别到。
在本申请的一些实施例中，音频中转设备可以通过混音处理使混音后数据中，目标广播音频数据的识别等级即第一识别等级，大于初始音频数据的识别等级即第二识别等级。
可选的，音频中转设备可以通过音量调节处理、频率调节处理等，使混音处理后的音频数据中目标广播音频数据更为突出。
在本申请的一些实施例中，图5为本申请实施例提出的音频传输方法的实现流程示意图三，如图5所示，在本申请的实施例中，音频中转设备对初始音频数据和目标广播音频数据进行混音处理，生成混音后音频数据，即步骤111可以包括以下步骤：
步骤111a、若音频中转设备的当前状态为输出初始音频数据，音频中转设备按照第一权重值对目标广播音频数据进行音量调节处理，获得第一音量的目标广播音频数据。
步骤111b、按照第二权重值对初始音频数据进行音量调节处理，获得第二音量的初始音频数据。
步骤111c、基于第一音量的目标广播音频数据和第二音量的初始音频数据生成混音后音频数据。
需要说明的是，在本申请的实施例中，音频中转设备可以利用表征不同音量大小的权重值对音频数据进行音量调节处理。
在本申请的一些实施例中，音频中转设备可以先按照第一权重值对广播音频数据进行音量调节处理，进而获得第一音量的广播音频数据；同时按照小于第一权重值的第二权重值对初始音频数据进行音量调节处理，进而获得第二音量的初始音频数据。
进一步的，音频中转设备便可以基于上述不同音量大小的两个音频数据生成混音后数据。
在本申请的一些实施例中，音频中转设备可以先进行广播音频数据和当前输出初始音频数据的解码处理，进而对解码后的数据进行基于音量权重值的混音处理，得到混音后数据，并对混音后数据再次进行编码，得到混音后音频数据，并将该混音后音频数据作为待传输音频数据。
步骤112、音频中转设备将混音后音频数据作为待传输音频数据。
进一步的，音频中转设备在进行声音的混音处理后，音频中转设备便可以将混音后的音频数据转发给音频输出设备进行播放。
详细的，音频中转设备可以采用弱化当前播放的其他非广播初始音频数据，而加强突出广播音频数据的方式进行声音的混音处理。如，音频中转设备可以把当前播放的其他初始音频数据的声音降低，以突出广播音频数据的声音。
这里，如果音频中转设备确定当前状态为输出初始音频数据，为了避免混音处理产生的声音不清晰的缺陷，以保证用户清晰且有效的收听到广播音频数据，音频中转设备可以按照时间先后顺序进行不同音频数据的发送过程。
在本申请的一些实施例中，图6为本申请实施例提出的音频传输方法的实现流程示意图四，如图6所示，在本申请的实施例中，音频中转设备根据初始音频数据和目标广播音频数据生成待传输音频数据可以包括以下步骤：
步骤113、若音频中转设备的当前状态为输出初始音频数据，音频中转设备直接将初始音频数据和目标广播音频数据作为待传输音频数据。
进一步的，音频中转设备将待传输音频数据发送至音频输出设备，即步骤120包括：
步骤121、音频中转设备停止初始音频数据的输出，将目标广播音频数据发送至音频输出设备，以使音频输出设备播放目标广播音频数据。
步骤122、在目标广播音频数据发送完成之后，音频中转设备继续向音频输出设备发送初始音频数据，以使音频输出设备继续播放初始音频数据。
在本申请的一些实施例中，音频中转设备可以在接收到广播音频数据时，暂停当前初始音频数据至音频输出设备的发送，先将广播音频数据发送至音频输出设备，进而使得音频输出设备播放当前的广播音频数据。
进一步的，在广播音频数据发送完成之后，音频中转设备可以向音频输出设备继续发送初始音频数据，使得音频输出设备接下来继续播放初始音频数据。
例如，当手机接收到登机广播时，此时，手机正在通过蓝牙耳机播放音乐，那么手机暂停音乐，先通过耳机仅播放登机广播，登机广播播放完成之后，手机继续通过耳机播放音乐。在本申请的一些实施例中，图7为本申请实施例提出的音频传输方法的实现流程示意图五，如图7所示，在本申请的实施例中，音频中转设备将待传输音频数据发送至音频输出设备之后，即步骤120之后，音频输出设备播放待传输音频数据可以包括以下步骤：
步骤131、音频输出设备按照第一音量播放目标广播音频数据，同时按照第二音量播放初始音频数据。
应理解，音频输出设备接收到的混音数据中，音频中转设备已按照能够表征音量大小的不同权重值对音频数据进行了音量调节处理，使得播放时广播音频数据更加突出于初始音频数据。因此，在本申请的实施例中，音频输出设备可以按照目标广播音频数据音量大于初始音频数据音量的播放策略进行播放。
例如，当手机接收到登机广播时，此时，手机正在通过蓝牙耳机播放音乐，那么手机可以对登机广播和音乐进行声音的混音处理，可以是将音乐的声音往下调一些，突出 这个重要登机广播的声音；或者也可以是直接把音乐数据的音量降为0，仅播放登机广播即可。
可选的，基于图6所示的音频传输方法，当待传输数据为按照时间先后顺序发送的不同的音频数据时，音频输出设备直接按照时间先后顺序对接收到的不同音频数据进行播放即可。
应理解，由于音频输出设备是一个被动的音频播放设备，只是被动的接收音频中转设备发送的音频数据。因此，在本申请的实施例中，当音频中转设备停止输出初始音频数据，而发送广播音频数据时，音频输出设备此时仅对接收到的广播音频数据播放即可；而当音频中转设备广播音频数据输出完成继续输出初始音频数据时，音频输出设备此时继续进行初始音频数据的播放。即音频输出设备在接收到音频中转设备发送的目标广播音频数据之后，播放目标广播音频数据；音频输出设备在接收到音频中转设备发送的初始音频数据之后，播放初始音频数据。
需要说明的是，如果音频中转设备确定当前状态为未向音频输出设备发送任何音频数据，即未输出初始音频数据，那么音频传输系统可以通过音频中转设备直接将接收到的广播音频数据发送至音频输出设备以进行播放。
综上所述，在本申请中，音频传输系统中，音频中转设备作为一个广播收集者的角色，音频中转设备可以是手机，也可以是电视TV，也可以是蓝牙网关。音频中转设备可以对接收到的广播信号进行音频解码后，将获取到的广播音频数据转发给音频输出设备，如耳机或音响。其中，如果转发时当前已有听歌业务在进行，则需要把广播和已有的音乐混音处理后转发给耳机或者音响，或者暂停已有的音乐先播放广播。可见，本申请耳机/音响不再需要自己去收听广播，而是基于与音频中转设备的蓝牙通信连接而接收音频中转设备转发的广播，如果断开音频中转设备与耳机的蓝牙通信连接，那么用户通过耳机便无法收听到广播。
本申请实施例提供了一种音频传输方法，音频传输系统包括音频中转设备和音频输出设备，在音频中转设备与音频输出设备建立无线通信连接之后，音频中转设备获取目标广播音频数据；若音频中转设备的当前状态为输出初始音频数据，则音频中转设备根据目标广播音频数据对初始音频数据进行混音处理，获得混音后音频数据，并将混音后音频数据发送至音频输出设备；音频输出设备按照第一音量播放目标广播音频数据，同时按照第二音量播放初始音频数据；其中，第一音量大于第二音量。也就是说，在本申请的实施例中，一方面不再需要音频输出设备，如耳机/音响自主的接收广播音频数据，而是通过音频中转设备来进行广播音频数据的采集，耳机/音响只需要连接并接收音频中转设备转发的音频数据即可，克服了耳机耗电量过大的缺陷；另一方面，音频传输系统在接收到广播音频数据之后，可以根据该广播音频数据和当前输出的其他音频数据生成待传输的目标音频数据，进而对该目标音频数据进行播放处理，解决了广播音频数据的播放与其他音频数据的播放存在时序冲突的问题，系统智能性高。
基于上述实施例，在本申请的再一实施例中，图8为本申请实施例提出的音频传输方法的实现流程示意图六，如图8所示，在本申请的实施例中，音频传输系统通过音频中转设备获取目标广播音频数据(步骤100)包括以下步骤：
步骤101a、在音频中转设备与音频输出设备建立无线通信连接之后，接收广播设备发送的无线广播信号。
步骤101b、对无线广播信号进行解码处理，获得目标广播音频数据。
需要说明的是，在本申请的实施例中，该广播设备可以为低功耗蓝牙(Bluetooth Low Energy，BLE)广播设备。
在本申请的一些实施例中，在本申请的实施例中，当外界的广播设备以BIG/BIS的 形式进行广播发送时，音频传输系统可以通过音频中转设备可以接收该广播设备发送的无线广播信号，并对该无线广播信号进行解码处理，进而得到目标广播音频数据，从而可将该解码后得到的广播音频数据进一步发送至音频输出设备。
应理解，广播设备普遍设置有广播接收权限和广播重要性，音频中转设备在执行来自于广播设备的广播音频数据的获取之前，音频中转设备可以先通过网络、定位、或者生态软件等常用方式获取外界相关广播设备对应的音频接收参数，进而基于上述音频接收参数执行无线广播信号的接收。
在本申请的一些实施例中，在本申请的实施例中，音频中转设备在进行无线广播信号的接收时，音频中转设备可以先获取广播设备对应的音频接收参数，然后基于该音频接收参数接收无线广播信号。
需要说明的是，上述音频接收参数可以包括广播设备对应的加密参数；或者上述音频接收参数可以包括广播设备对应的优先级别；或者上述音频接收参数既可以包括加密参数，也可以包括优先级别。
进一步地，在本申请的一些实施例中，在音频接收参数包括加密参数的情况下，图9为本申请实施例提出的音频传输方法的实现流程示意图七，如图9所示，音频传输系统通过音频中转设备接收广播设备发送的无线广播信号包括：
步骤101a1、在音频中转设备与音频输出设备建立无线通信连接之后，获取广播设备对应的加密参数。
步骤101a2、基于加密参数接收无线广播信号。
在本申请的一些实施例中，加密参数不限制于广播设备对应的设备名称以及广播接收密码。
这里，音频中转设备在基于配置信息获取到广播设备对应的加密参数之后，音频中转设备便可以在参数设置界面输入所需要接收的广播的设备名称，以及该设备名称所对应的密码，音频中转设备便可以响应该操作，基于该加密参数获取到该目标广播信号的接收权限，从而便可以进一步进行对目标广播信号的接收，以获取目标广播音频数据。
在本申请的一些实施例中，在音频接收参数包括优先级别的情况下，图10为本申请实施例提出的音频传输方法的实现流程示意图八，如图10所示，音频传输系统通过音频中转设备接收广播设备发送的无线广播信号的方法包括：
步骤101a3、在音频中转设备与音频输出设备建立无线通信连接之后，获取广播设备对应的优先级别。
步骤101a4、根据优先级别接收无线广播信号。
应理解，外界存在多个不同的广播设备，根据设备自身配置或者用户需求，各广播设备对应的优先级别存在差异，如火警设备对应的广播优先级别始终处于最高优先级；可见，如果出现同一时刻存在多个广播，为了避免出现广播调度产生冲突的问题，音频中转设备可以基于广播设备的配置信息先获取各个广播设备对应的广播接收优先级，或者用户可以根据实际需要在操作界面手动设置各广播的优先级别，进而音频中转设备响应上述操作，按照该优先级别由高到低的顺序进行对目标广播信号的接收，以获取目标广播音频数据。
例如，如果当前同时存在站点播报器和火警报警器正在广播，由于火警广播处于最高优先级，因此手机可以选择优先接收火警报警器发送的无线广播信号。
进一步的，在本申请的实施例中，如果存在多个优先级相同的广播信号，为了避免多个广播之间的时序冲突，音频中转设备可以配置多天线接收，也就是能够同时接收多个无线广播信号，避免多个广播信号之间的时序冲突。
应理解，音频中转设备可以配置多个接收天线，如第一接收天线和第二接收天线， 音频中转设备可以利用第一接收天线接收第一广播设备发送的第一无线广播信号，同时通过第二广播设备接收第二设备发送的第二无线广播信号，从而避免了多个广播之间信号接收时的时序冲突。
进一步的，在本申请的实施例中，音频传输系统通过音频中转设备获取该广播音频数据的同时，还可以通过音频中转设备实时检测自身当前是否正在进行其他非广播音频数据的输出，即检测当前音频输出状态(步骤102)，进而结合当前音频输出状态执行目标广播音频数据的转发处理。
可见，在本申请中，音频传输系统可以通过音频中转设备，根据广播设备对应广播配置信息，如加密参数、广播信号接收优先级别等执行无线广播信号的接收流程，进而在完成该广播信号的解码，获取到广播音频数据之后，进一步通过音频中转设备将广播音频数据转发至音频输出设备，不仅克服了耳机耗电量过大的缺陷，而且解决了广播音频数据播放与当前音频播放存在时序冲突的问题，音频中转设备智能性高。
基于上述实施例，在本申请的再一实施例中，图11为本申请实施例提出的音频传输方法的实现流程示意图九，如图11所示，在本申请的实施例中，音频传输系统通过音频中转设备获取目标广播音频数据(步骤100)包括以下步骤：
步骤101c、在音频中转设备与音频输出设备建立无线通信连接之后，通过声音采集模块采集广播设备播放的当前广播音频数据，并检测当前位置状态；
步骤101d、若当前位置状态为目标位置，则将当前广播音频数据确定为目标广播音频数据。
可以理解的是，如果广播设备通过扬声器或者喇叭播放广播音频数据，音频传输系统可以通过音频中转设备中的声音采集模块如麦克风，实时采集广播音频数据，由于采集到的这些广播音频数据并不全是用户所需的，那么音频中转设备可以结合当前位置状态确定出用户所需要收听的目标广播音频数据。
在本申请的一些实施例中，音频传输系统可以通过音频中转设备实时检测当前位置状态，如果当前位置状态为目标位置状态，那么音频中转设备可以将此时通过麦克风采集到的广播音频数据确定为目标广播音频数据，并进一步转发至音频输出设备，如蓝牙耳机。
例如，乘客乘坐飞机，手机可以通过机场里面的WIFI信号、或者卫星定位获取乘客的实时位置信息，当得知乘客当前位于机场内时，手机通过麦克风采集机场登机广播并转发给乘客。详细的，音频中转设备还可以结合乘客的目标航班登机信息，当得知乘客当前位于机场内时，且采集到的登机提醒为用户的目标航班登机提醒，那么音频中转设备可以将采集到的当前广播音频数据确定为目标广播音频数据，并进一步转发至音频输出设备，如蓝牙耳机。
例如，乘客乘坐地铁，手机可以通过地铁里面的WIFI信号、或者卫星定位获取乘客的实时位置信息，当乘客到达某一站点时，手机可以将当前通过麦克风接收到的站点报站广播转发给带蓝牙耳机的乘客。
可见，在本申请中，音频传输系统可以通过音频中转设备中的麦克风采集广播音频数据，并通过音频中转设备将广播音频数据转发至音频输出设备，不仅克服了耳机耗电量过大的缺陷，而且解决了广播音频数据与当前音频播放存在时序冲突的问题，音频中转设备智能性高。
基于上述实施例，在本申请的再一实施例中，图12为本申请实施例提出的音频传输方法的应用场景示意图一，假定音频中转设备为一台手机，音频传输设备为耳机，如图12所示，在本申请的实施例中，手机在与无线耳机建立蓝牙通信连接(如ACL链路或者BT5.2新引入的CIG/CIS链路)之后，手机可以接收门铃，火警报警器，机场、商 场、火车站广播，或者地铁报站器中的任意一个或多个设备发送的BIG/BIS广播，并进行解码获得广播音频数据。如果手机当前通过无线耳机正在播放其他音频数据，那么手机可以对广播音频数据和其他音频数据进行混音处理，使得混音后音频数据中着重突出广播音频数据，进而将混音后音频数据发送至无线耳机以实现用户收听广播。如果手机当前通过无线耳机并没有播放其他音频数据，那么手机可以将广播音频数据直接发送至无线耳机以实现用户收听广播。
基于上述实施例，在本申请的再一实施例中，图13为本申请实施例提出的音频传输方法的应用场景示意图二，假定音频中转设备为一台网关或者电视，音频传输设备为耳机/音响，如图13所示，在本申请的实施例中，客厅的网关在与音响建立蓝牙通信连接(ACL链路或者BT5.2新引入的CIG/CIS链路)之后，网关可以接收门铃，火警报警器，厨房电器广播，或者客厅电器广播中的任意一个或多个设备发送的BIG/BIS广播，并进行解码获得广播音频数据。如果客厅网关当前通过音响正在播放其他音频数据，那么网关可以先对广播音频数据和其他音频数据进行混音处理，使得混音后音频数据中着重突出广播音频数据，进而将混音后音频数据发送至音响以实现用户收听广播。如果网关当前通过音响并没有播放其他音频数据，那么网关可以将广播音频数据直接发送至音响以实现用户收听广播。
本申请实施例提供了一种音频传输方法，一方面不再需要音频输出设备，如耳机/音响自主的接收广播音频数据，而是通过音频中转设备来进行广播音频数据的采集，耳机/音响只需要连接并接收音频中转设备转发的音频数据即可，克服了耳机耗电量过大的缺陷；另一方面，音频中转设备可以对广播音频数据和当前输出的其他初始音频数据进行混音处理，将其他初始音频数据的音量下降，突出广播音频数据，进而解决了广播音频数据的播放与其他初始音频数据的播放存在时序冲突的问题，智能性高。
