Description
本申请要求于2021年06月16日提交国家知识产权局、申请号为202110665714.4、申请名称为“终端设备通过蓝牙外设拾音的方法及终端设备”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。
本申请涉及通信技术领域,尤其涉及一种终端设备通过蓝牙外设拾音的方法及终端设备。
目前,在用户使用手机中的应用程序(application,APP)进行直播、拍摄视频、视频通话等音视频场景中,通常是通过手机内置的麦克风或者是插入手机的耳麦拾取被拍摄者的声音。当被拍摄者与手机距离较近时,手机的麦克风拾音效果较好;随着手机与被拍摄者之间的距离越来越远,通过手机的麦克风拾取被拍摄者的声音的强度会越来越小,导致拍摄的视频声音效果较差。因此,当被拍摄者与手机之间的距离较远或者手机周围环境噪声太大时,均会影响手机麦克风拾音的效果。
发明内容

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。
本文中术语“和/或”,是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。本文中符号“/”表示关联对象是或者的关系,例如A/B表示A或者B。
本文中的说明书和权利要求书中的术语“第一”和“第二”等是用于区别不同的对象,而不是用于描述对象的特定顺序。例如,第一音效处理参数和第二音效处理参数等是用于区别不同的音效处理参数,而不是用于描述音效处理参数的特定顺序。
在本申请实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本申请实施例的描述中,除非另有说明,“多个”的含义是指两个或者两个以上,例如,多个处理单元是指两个或者两个以上的处理单元等;多个元件是指两个或者两个以上的元件等。
为便于理解本申请实施例,以下对本申请实施例的部分用语进行解释说明,以便于本领域技术人员理解。
(1)SCO:同步定向连接(synchronous connection oriented link,SCO),也称为SCO链路。SCO链路或扩展的SCO(extended SCO,eSCO)链路用于传输对时间要求很高的通信数据,主要用于同步话音传送(例如音视频业务)。需要说明的是,本申请实施例提供的方案中不限定SCO链路还是eSCO链路,为了便于说明,下文以SCO链路为例对本方案进行示例性的描述。
(2)HFP:免提规范(hands-free profile,HFP),代表免提功能。如果蓝牙设备支持HFP规范,且蓝牙设备与终端设备之间激活HFP规范,那么终端设备与蓝牙耳机之间可以基于HFP规范传输音频数据流。
(3)A2DP:高级音频分发规范(advanced audio distribution profile,A2DP),支持传输立体声音频数据流。A2DP规范定义了音频数据流的源端(source,简称为src)和音频数据流的接收端(简称为sink)。作为音频数据流的源端的设备(例如手机)和作为接收端的设备(例如蓝牙耳机)可以基于A2DP规范传输高质量音频信息(即音频数据流)。
(4)DRC:动态范围控制(dynamic range control,DRC),一种音效处理方式,DRC对应的音效处理参数称为音效DRC参数,通过调节信号幅度,可调整声音电平的动态范围,改善音效。其中,声音电平的动态范围即指最大音量和最小音量之间的范围,也可以采用最大音量和最小音量的差值来衡量动态范围的大小。
示例性地,可以对时间轨上的音频数据进行以下处理:针对声音电平低于预设最小门限的音频数据,按预先设置的音效DRC参数提升音量;针对声音电平超过预设最高门限的音频数据,按预先设置的DRC参数降低音量,这样调整声音电平的动态范围,即减小了动态范围。在音频处理效果上来看,对于声音音量较低的部分,由于音效处理而音量增大,处理后的声音可变得更加清晰;对于声音音量较高的部分,由于音效处理而音量适当降低,处理后的声音可变得更加柔和。从整体效果来看,处理后的声音效果更能满足用户使用需求,可提升用户体验。
图1示出了本申请的各个示例性实施例所涉及的通信系统的架构示意图。如图1所示,通信系统10可以包括终端设备11和蓝牙设备12(称为蓝牙外围设备,可简称为蓝牙外设),终端设备11和蓝牙设备12可以通过蓝牙(bluetooth,BT)通信协议建立蓝牙连接并通信。其中,上述蓝牙通信协议可以为传统蓝牙协议,也可以为低功耗蓝牙(bluetooth low energy,BLE)协议;当然,还可以是未来推出的其他新的蓝牙协议类型。
可选的,终端设备11可以是智能手机、平板电脑、个人数字助理(personal digital assistant,PDA)、电视或智能手表等电子设备。需要说明的是,在本申请实施例中,终端设备11设置有用于采集图像数据的摄像头,以及用于采集声音数据的麦克风,即终端设备11具有录制音视频的功能。这样,通过终端设备11可以实现直播、视频通话、录像或者录音等音视频业务。
可选的,蓝牙设备12可以是蓝牙麦克风,蓝牙耳机,无线音箱,无线手环,无线车 载,无线智能眼镜,无线手表,增强现实(augmented reality,AR)/虚拟现实(virtual reality,VR)设备,媒体播放器(例如MP3、MP4等)、笔记本电脑、PDA、电视或智能手表等支持蓝牙通信协议的电子设备。需要说明的是,在本申请实施例中,蓝牙设备12设置有麦克风,具有采集声音数据的功能。
示例性的,以蓝牙设备12为蓝牙耳机为例进行说明,蓝牙耳机12可以有多种类型,例如可以是耳塞式、入耳式、头戴式、耳罩式或挂耳式蓝牙耳机等。示例性地,蓝牙设备12可以为真无线立体声(true wireless stereo,TWS)耳机,也可以为颈带式蓝牙耳机。
在一些实施例中,蓝牙耳机12可以支持下述应用中的一种或多种:HSP(headset profile)应用、HFP应用、A2DP应用。其中,HSP应用代表耳机应用,提供手机与蓝牙耳机之间通信所需的基本功能,蓝牙耳机可以作为手机的音频输入和输出接口。HFP应用代表免提应用,HFP应用在HSP应用的基础上增加了某些扩展功能,蓝牙耳机可以控制手机的音视频通话或者录制过程,例如接听、挂断、拒接、语音拨号等。A2DP应用为高级音频传送应用,支持传输立体声音频流。在实际实现时,在蓝牙耳机与终端设备保持蓝牙连接的情况下,用户可以佩戴蓝牙耳机进行听音乐或接/打电话等音频业务。
本申请实施例对终端设备11和蓝牙设备12的设备类型不予具体限定。为了便于说明,下文中以终端设备11为手机,蓝牙设备12为蓝牙耳机为例进行示例性地说明。
下面结合图2说明终端设备在进行直播、视频通话、录像或者录音等音视频业务的场景中存在的问题。
如图2中的(a)所示,在用户13通过终端设备11进行直播、视频通话、录像或者录音等音视频业务的场景中,通常是由终端设备11的麦克风拾取用户13的声音,得到用户音频数据,图2中简称为手机mic拾音。但是,由于终端设备11与用户13之间的距离大于一定距离阈值,或者终端设备11和用户13周围的环境嘈杂等原因,可能会导致通过终端设备11的麦克风拾取到的声音音量较小,拾音效果不佳。
本申请方案提出如下方案,如图2中的(b)所示,在用户13通过终端设备11进行直播、视频通话、录像或者录音等音视频业务的场景中,如果用户13佩戴有蓝牙设备12(例如蓝牙耳机,支持HFP规范)且该蓝牙设备12与终端设备11已建立蓝牙连接,那么可以由蓝牙设备12的麦克风拾取用户13的声音,图2中简称为蓝牙mic拾音,这样拾取到的声音音量大大提升。进一步地,蓝牙设备12将拾取到的用户音频数据发送给终端设备11。
在终端设备进行音视频业务的场景中,可以通过蓝牙外设采集声音,提升音量,但是由于目前蓝牙外设种类众多,其配置的麦克风语音采集功能差异较大,或者由于蓝牙信道质量不佳或者受到干扰,这样会导致通过蓝牙外设拾取到的用户音频数据在音效上并不好,无法满足用户需求,影响用户使用体验。
鉴于此,本申请实施例提供了一种终端设备通过蓝牙外设拾音的方法及终端设备,不仅可以实现终端设备通过蓝牙外设拾音,而且可以改善通过蓝牙外设拾音的音效。在终端设备进行直播、视频通话等音视频业务的场景中,终端设备可以通过蓝牙外设的麦克风拾取声音数据,并且可以采用与该蓝牙外设对应的预设音效DRC参数,对蓝牙外设拾取的声音数据进行针对性地音效处理,改善音效。通过本申请方案,不仅可以实现终端设备通过蓝牙外设拾音,而且还可以针对不同蓝牙外设分别采用不同的预设音效DRC参数进行音效处理,改善通过蓝牙外设拾音的音效,即使终端设备与被拍摄者距离较远或者周围环 境噪声较大,也可实现较好的录音效果,提升用户使用体验。
本申请实施例提供的终端设备通过蓝牙外设拾音的方法的执行主体可以为上述的终端设备,也可以为该终端设备中能够实现该终端设备通过蓝牙外设拾音的方法的功能模块和/或功能实体,并且本申请方案能够通过硬件和/或软件的方式实现,具体的可以根据实际使用需求确定,本申请实施例不作限定。下面以终端设备为例,结合附图对本申请实施例提供的终端设备通过蓝牙外设拾音的方法进行示例性的说明。
图3是本申请实施例提供的终端设备通过蓝牙外设拾音的方法的流程示意图。参照图3所示,该方法100包括下述的步骤S101-S110。
S101,终端设备接收到用户通过第一APP进行音视频业务的第一操作。
S102,终端设备响应于第一操作,判断终端设备是否与蓝牙设备建立蓝牙连接。
其中,上述音视频业务可以包括直播、视频通话、语音通话、录像或者录音等涉及音视频录制或通话的业务,可以理解,这里为示例性地列举,在实际实现时,上述音视频业务还可以包括其他任意可能的音视频业务,本申请实施例对此不作限定。在终端设备处理音视频业务时,会涉及声音数据(例如用户语音数据)的采集或拾取,通常默认由终端设备的麦克风采集或拾取声音数据。例如,在手机录制音视频时通常是默认使用手机内置麦克风或者是插入的耳麦来实现录音的。
在本申请实施例中,上述第一APP为终端设备中安装或加载的支持音视频业务的应用程序,可以是系统APP,也可以是第三方APP,本申请实施例对此不作限定。
当用户在终端设备上操作,触发开启第一APP的音视频业务时,终端设备可以检测到用户的第一操作,并响应于该第一操作,指示终端设备开启麦克风,以通过终端设备的麦克风拾取声音数据(例如用户语音数据),或者指示与终端设备连接的蓝牙设备开启麦克风,以通过蓝牙设备的麦克风拾取语音数据。具体是由终端设备的麦克风拾取语音数据,还是由蓝牙设备的麦克风拾取语音数据,终端设备可以根据具体情况进行确定。具体情况可能是终端设备未与其他蓝牙设备建立连接,也可以是终端设备与某个蓝牙设备保持蓝牙连接。
一方面,若终端设备与某一蓝牙设备已建立蓝牙连接且该蓝牙设备支持HFP规范,则终端设备继续执行下述的步骤S103-S106,即指示与终端设备连接的蓝牙设备开启麦克风,以通过蓝牙设备的麦克风拾取语音数据。
在实际实现时,随着手机与被拍摄者之间的距离越来越远,通过手机的麦克风拾取被拍摄者的声音的强度会越来越小,导致拍摄的视频声音效果较差。如果此时手机与蓝牙外设已建立连接,那么可以选择通过蓝牙外设的麦克风拾取声音,提升拾音效果。
另一方面,若终端设备未与任何蓝牙设备建立蓝牙连接,或者终端设备与某一蓝牙设备已建立蓝牙连接但该蓝牙设备不支持HFP规范,则终端设备继续执行下述的步骤S107-S110,即指示终端设备开启麦克风,以通过终端设备的麦克风拾取语音数据。
其中,上述第一操作可以为用户在终端设备上触发启用音视频业务或服务的操作,例如通过触摸方式触发或者语音方式触发的各种可能操作,具体可以根据实际使用需求确定,本申请实施例不作限定。
S103,在终端设备与蓝牙设备已建立蓝牙连接且蓝牙设备支持HFP规范的情况下,终端设备向蓝牙设备发送麦克风开启指令。
在本申请实施例中,终端设备向蓝牙设备发送麦克风开启指令,即终端设备发起与蓝牙设备建立SCO连接,以指示蓝牙设备开启麦克风。进一步地,蓝牙设备在开启麦克风之后,可以向终端设备发送响应消息,用于指示蓝牙设备的麦克风已开启。
其中,终端设备与蓝牙设备建立SCO连接,可以直接触发蓝牙设备开启麦克风。即,若终端设备与蓝牙设备建立SCO连接,则默认蓝牙设备已开启麦克风,在此情况下蓝牙设备具有拾取语音数据并将拾取的语音数据实时传输给终端设备的功能。
需要说明的是,上文中是以一旦终端设备发现与蓝牙设备已建立连接,就直接触发蓝牙设备的麦克风进行语音数据拾取为例进行示例性说明的,本申请实施例包括但不限于此,可以理解,在实际实现时,当终端设备发现与蓝牙设备已建立连接时,终端设备可以先提示用户是需要由终端设备的麦克风进行语音数据拾取,还是需要由蓝牙设备的麦克风进行语音数据拾取,供用户选择。进一步地,如果用户选择由蓝牙设备的麦克风进行语音数据拾取,那么终端设备可以响应于用户的选择操作,向蓝牙设备发送麦克风开启指令,指示蓝牙设备开启麦克风并进行语音数据拾取。
可选地,在本申请实施例中,当终端设备发现与蓝牙设备已建立连接时,终端设备可以判断该蓝牙设备是否满足预设条件,例如蓝牙设备处于用户佩戴状态,和/或,蓝牙设备与终端设备之间的距离大于预设距离阈值。当该蓝牙设备满足预设条件时(例如蓝牙设备处于用户佩戴状态),终端设备提示用户是否需要由蓝牙设备的麦克风进行语音数据拾取,供用户选择。这样可以更好地满足用户使用需求,提升用户使用体验。
可选地,在本申请实施例中,在终端设备处理音视频业务,且通过蓝牙设备的麦克风进行语音数据拾取的情况下,终端设备可以判断该蓝牙设备是否满足上述预设条件。当该蓝牙设备不满足预设条件时,例如蓝牙设备处于用户未佩戴状态,终端设备提示用户是需要由蓝牙设备的麦克风进行语音数据拾取,切换到由终端设备的麦克风进行语音数据拾取,供用户选择。这样可以更好地满足用户使用需求,提升用户使用体验。
S104,终端设备接收蓝牙设备发送的由蓝牙设备的麦克风采集的第一音频数据流。
在终端设备处理音视频业务的过程中,在终端设备与蓝牙设备建立SCO连接之后,蓝牙设备可以通过麦克风实时拾取周围的声音数据(例如用户语音数据),即第一音频数据流。进一步地,蓝牙设备可以通过SCO连接,将第一音频数据流发送给终端设备。
S105,终端设备采用与蓝牙设备对应的第一音效处理参数对第一音频数据流进行处理,得到处理后的第一音频数据流。
具体到本申请方案,如上文所述,在终端设备进行音视频业务的场景中,尽管可以通过蓝牙外设采集声音,提升音量,但是由于各种原因导致终端设备通过蓝牙设备拾取的语音数据在音效上不能满足用户需求,因此终端设备在接收蓝牙设备发送的第一音频数据流之后,需要对第一音频数据流进行特定的音效处理,以改善第一音频数据流的音效。
在本申请实施例中,终端设备中可以预设有音效参数库。其中,音效参数库中可以包括蓝牙设备信息与音效处理参数的一一对应关系。终端设备可根据实际使用需求,根据蓝牙设备信息从音效参数库中调用对应的音效处理参数。
需要说明的是,不同类型的蓝牙设备可以预设对应的音效处理参数,具体音效处理参数的取值可以根据实验室数据确定。这样,本申请方案针对蓝牙外设麦克风拾取的音频流,可以采用针对该蓝牙外设类型预设的音效处理参数进行音效处理,可提升音频质量。

参考上述图5中的(a)和(b)可知,当第三方APP(小视频应用或平台等)在调用音频接口以打开手机麦克风进行拾音(例如录音)时,手机先判断当前是否有连着支持HFP特性的蓝牙外设,如果否,则手机继续走原有流程打开手机麦克风,通过手机麦克风进行拾音;如果是,则手机调用蓝牙模块与蓝牙外设建立SCO通路,触发通过蓝牙外设麦克风拾音。
与上述图4示出的现有技术中手机处理音视频业务时通过手机麦克风拾音的实现过程相比,图5中示出的本申请实施例中手机处理音视频业务时可以根据实际应用场景选择通过手机麦克风拾音,或者通过蓝牙外设麦克风拾音,可提升拾音效果;并且本申请实施例中针对蓝牙外设麦克风拾取的音频流,采用针对该蓝牙外设类型预设的音效处理参数进行音效处理,可提升音频质量。
在本申请实施例中,在蓝牙外设已经连接手机的情况下,如果第三方APP发起录音请求,那么手机可以更改APP使用手机麦克风的请求,将音频通道路由为蓝牙外设,从而手机可以通过蓝牙外设拾音,并且本申请方案可以采用一种更加准确的设备分类方案,针对不同类型的蓝牙外设启用不同的音效DRC参数,对蓝牙外设拾取的音频流进行音效处理, 从而达到提升通过蓝牙外设拾音效果的目的。
可选地,在本申请实施例中,为了保证通过APP发起的音视频业务能够正常进行,某些APP在触发开启麦克风之后会向手机发送麦克风状态查询指令,以查询麦克风是否处于开启状态。需要说明的是,由于本申请方案中有改进,即音频路由转换,因此对手机麦克风状态的查询,要切换至对蓝牙麦克风状态的查询。

可选地,在本申请实施例中,为了保证通过APP发起的音视频业务能够正常结束,APP会向手机发送麦克风关闭指令,用于指示麦克风关闭。需要说明的是,由于本申请实施例基于现有技术方案有改进,即音频路由转换,因此对手机麦克风的关闭动作,要切换至对蓝牙SCO连接的断开动作。
下面参考图7示例性地描述本申请实施例提供的终端设备通过蓝牙外设拾音的方法中的麦克风关闭流程。结合图5,如图7所示,方法300还包括下述的步骤S327-S334。

这样,在通过APP实现的音视频业务结束时,手机可以根据实际情况触发关闭麦克风的语音采集功能,可满足用户实际使用需求,提升用户使用体验。
下面再结合图8,示例性地说明本申请实施例提供的终端设备通过蓝牙外设拾音的方法中确定蓝牙外设对应的音效处理参数的实现过程。如图8所示,该实现过程包括下述的步骤S401-S405。
S401,手机判断蓝牙外设是否支持HFP规范。
示例性地,手机的音频算法模块可以预先查询当前蓝牙外设的设备相关信息,根据蓝牙外设的设备相关信息可以判断蓝牙外设是否支持HFP规范。
若蓝牙外设支持HFP规范,则继续执行下述的步骤S402;若蓝牙外设不支持HFP规范,则采用手机麦克风拾音。
S402,手机判断蓝牙外设是否支持显示功能。
若蓝牙外设支持显示功能,则手机可以确定蓝牙外设为车载/PC/PDA/手机等设备类型;若蓝牙外设不支持显示功能,则手机可以确定蓝牙外设为耳机/音箱等设备类型。
S403,在确定蓝牙外设为车载/PC/PDA/手机等设备类型的情况下,判断蓝牙外设作为A2DP规范的src端(源端)还是sink端(接收端)。
若蓝牙外设作为A2DP规范的src端,则手机可以确定蓝牙外设为PC/PDA/手机等类型;若蓝牙外设作为A2DP规范的sink端,则手机可以确定蓝牙外设为车载类型。
S404,手机根据蓝牙外设的设备相关信息,从预设的设备库中确定蓝牙外设的具体型号。
例如,假设蓝牙外设为耳机/音箱等设备类型,手机可以从预设的设备库中确定耳机具体型号/音箱具体型号。
再例如,假设蓝牙外设为车载设备类型,手机可以从预设的设备库中确定具体车型。
在本申请实施例中,手机的音频算法模块预先查询当前蓝牙外设的厂家标识、设备类 型、I/O能力等信息,可以将蓝牙外设区分为车载蓝牙设备以及普通蓝牙设备(例如蓝牙耳机或音箱),再通过蓝牙外设的MAC地址、厂家标识和设备名称,识别出蓝牙外设具体是哪个型号的设备。
需要说明的是,如果该蓝牙外设无法与任何一个厂家的型号匹配,那么可以启用该设备类型的通用参数。
S405,手机根据蓝牙外设的具体型号,从预设的音效参数库中确定蓝牙外设对应的音效处理参数。
与现有技术相比,本申请方案增加了音效处理流程。其中,新增了设备分类方案,针对不同类型的蓝牙外设可以启用不同音效DRC参数,并且对于无法归并到某个具体型号的设备可以使用该类别的通用音效参数。
这样,在手机蓝牙模块将音频流输入给音频算法模块之后,音频算法模块启用音效处理参数对音频流进行音效处理。具体地,音频算法模块可以针对蓝牙外设选取对应的音效处理参数,其中音效处理参数可以体现为调整DRC参数。
在本申请实施例中,本申请方案不仅可以应用于TWS空间立体声效果,也可以推广应用于蓝牙音箱或者其他任意蓝牙外设。

这样,当第一APP获知麦克风处于开启状态时,可以继续进行音视频录制或通话。当第一APP获知麦克风处于关闭状态时,可以重新触发开启麦克风,以保证第一APP发起的音视频业务能够正常进行,提升用户体验。
在一种可能实施方式中,检测单元710还用于:
