Description

VR眼镜和VR眼镜的声音播放方法 技术领域
本公开涉及但不限于通信领域。
背景技术
在相关技术中，随着3D眼镜、虚拟现实(Virtual Reality，简称为VR)眼镜的出现，3D视觉体验的概念已经慢慢普及到了人们的生活中，为达到更加良好的听觉体验，人们开始追求更完美的3D音效。3D Imax是3D视觉的一个的实例，杜比全景声影院是3D音效的一个实例。
然而，前面提到的3D音效需要在固有场所(家庭影院、电影院等)体验。另一方面，可以通过耳机来实现虚拟环绕音效，然而，长时间使用耳机会让人耳产生疲劳，且耳机无法实现真正的3D音效。
发明内容
一方面，本公开提供了一种虚拟现实(VR)眼镜。所述VR眼镜包括：眼镜本体，配置为基于与所述VR眼镜连接的移动终端所传输的视频信号播放视频；至少两个VR扬声器，配置为基于所述移动终端传输的音频信号播放声音。
另一方面，本公开还提供了一种虚拟现实(VR)眼镜的声音播放方法，包括：将VR眼镜连接至移动终端，其中，所述VR眼镜包括至少两个VR扬声器；通过VR眼镜接收所述移动终端传输的音频信号；至少通过所述至少两个VR扬声器播放基于所述音频信号的声音。
另一方面，本公开还提供了一种存储介质，所述存储介质上存储有程序，所述程序运行时执行本文所述的方法。
另一方面，本公开还提供了一种处理器，所述处理器用于运行程序，所述程序运行时执行本文所述的方法。

具体实施方式
相关技术中的VR眼镜技术主要用于3D视觉体验，而其音频播放主要是依赖于所连接设备(例如，手机等)的扬声器或者耳机。扬声器播放的单声道音源只能达到普通的播放效果，耳机的虚拟立体声的效果也只能虚拟出空间感，无法达到3D临场感。
双声道立体声的音质和声场效果好于单声道，但在家庭影院应用方面，它的局限性也暴露了出来。双声道立体声系统只能再现一个二维平面的空间感，即整个声场是平的，并不能使听众有置身其中的现场感。因此，相关技术中提出的多声道技术的优势才得以体现出来。
5.1声道是使用5个扬声器和1个超低音扬声器来达到一种身临 其境感觉的音频播放方式，由杜比公司开发。声道是指音频信号通过扬声器的通道。超低音扬声器发出的声音是听不出什么内容的，所以既然这个声道并不是一个独立声道，也就习惯性地将其表示成0.1声道。如果在只包含左右两个扬声器的立体声音响上再加上一个超低音扬声器，就称作2.1声道。
在5.1声道方式中，5个扬声器是在通常的前左、前右的2个立体声扬声器的基础上，再分别在正中和左后、右后等三个方位配置三个扬声器。因为前后左右都有扬声器，就会产生被声音包围的真实感。超低音扬声器只用来表现120Hz以下的超低音。由于超低音的表现与声音的方向性关系不大，因此这个超低音扬声器并没有规定特定的放置方位。
杜比7.1环绕声(Dolby Surround 7.1)是由美国杜比实验室研发的音响格式，在5.1声道的基础上，通过增加两个分离式声道(例如，增加两个后置声道)来提高声音效果。
然而，针对相关技术中使用VR眼镜观看视频时无法真正实现3D音效的问题，目前还没有有效的解决方案。期望能有一款便携式的设备可以支持3D音效，从而可以随时随地的体验到3D音效。
因此，本公开特别提供了一种VR眼镜和VR眼镜的声音播放方法，其实质上避免了由于相关技术的局限和缺点所导致的问题中的一个或多个。
本申请实施例中提供了一种VR眼镜，包括眼镜本体和至少两个VR扬声器，至少两个VR扬声器用于形成多声道音效。
一方面，本公开提供了一种VR眼镜的声音播放方法。图1是根据本公开实施例的一种VR眼镜的声音播放方法的流程图。如图1所示，所述方法包括如下步骤S102至S106。
在步骤S102，将VR眼镜连接至移动终端，其中，该VR眼镜包括至少两个VR扬声器。
在步骤S104，通过VR眼镜接收该移动终端传输的音频信号。
在步骤S106，至少通过该至少两个VR扬声器播放基于该音频信号的声音。
根据本公开，VR眼镜设置有至少两个VR扬声器，使用该VR眼镜观看视频时，配合移动终端自身的扬声器，可以营造出多声道音效。或者，根据本公开的VR眼镜可以单独营造出多声道音效。因此，根据本公开实施例，解决了相关技术中使用VR眼镜观看视频时无法实现多声道音效的问题，实现了VR视频的多声道音效，提升了用户的观看体验。
在一些实施例中，在该VR眼镜包括两个VR扬声器，连接至该VR眼镜的移动终端包括两个移动终端扬声器的情况下，至少通过该至少两个VR扬声器播放基于该音频信号的声音，包括：通过该两个VR扬声器和该两个移动终端扬声器进行四声道播放。
在一些实施例中，在该VR眼镜包括多于两个VR扬声器的情况下，通过VR眼镜接收该移动终端传输的音频信号，至少通过该至少两个VR扬声器播放基于该音频信号的声音，包括：接收经过该移动终端处理的多声道的音频信号，解析该音频信号并传输至该多于两个VR扬声器进行播放。
在一些实施例中，在该VR眼镜包括多于两个VR扬声器的情况下，通过VR眼镜接收该移动终端传输的音频信号，至少通过该至少两个VR扬声器播放基于该音频信号的声音，包括：接收该移动终端传输的音频信号，对该音频信号进行多声道音效处理，并将处理后的音频信号传输至该多于两个VR扬声器进行播放。

下面结合本公开的各种实施例对本公开的技术方案进一步说明。
本公开提出一系列便携式VR眼镜，能装载智能手机使用，可以在使用者通过VR眼镜观看视频(例如，3D视频、VR视频等)的同时，播放3D音效的声音，达到3D视觉和音效的体验。当然，本公开的VR眼镜也可以仅播放基于音频信号的声音以实现3D音效。此外，需要注意的是，在本公开的一些实施例中，智能手机不是必须的，比如，VR眼镜的眼镜本体自身可以实现播放视频的功能。
下面详细描述多声道音效在VR眼镜上的实现方式。
图2是根据相关技术中的杜比多声道环绕立体声方案中的扬声器布局的示意图。如图2所示，用户处于房间中央，环绕用户的周围设置有多个扬声器，用于形成多声道环绕立体声效果。在图2中，设置有左前、右前、前方、左侧、右侧、左后、右后和超低音扬声器， 即，图2中的扬声器布局可以实现杜比7.1环绕声。
根据本公开的一个实施例，VR眼镜通过耳机接口，配合双扬声器手机实现4.1声道音效。
在一个示例中，需要一款双扬声器手机(装载特制的杜比音效软件)，一款可以装载手机的VR眼镜，VR眼镜的眼镜带上有2颗扬声器，在把手机装置到VR眼镜之后，VR眼镜上的两颗扬声器通过手机的耳机接口连通到手机电路上。图3是根据本公开实施例的实现多声道音效的VR眼镜的示意图。参照图3，在播放视频时，手机中的杜比音效软件将杜比5.1声道音源(音频信号)转换成4声道音源，并将其分别输出至手机的2颗扬声器和VR眼镜上的2颗扬声器，从而分别由手机的2颗扬声器和VR眼镜上的2颗扬声器同时播放出来，达到最接近杜比4.1声道声场还原的效果。VR眼镜的扬声器需要按照左后、右后的布局位置设置。如图3所示，在VR眼镜的眼镜带上设置有2颗扬声器。
根据本公开的另一个实施例，VR眼镜通过USB(通用串行总线)Type C/蓝牙接口的数据传输，配合手机实现双声道、5.1声道或7.1声道音效。
在一个示例中，需要一款支持OTG(On-The-Go)的手机，一款可以装载手机的VR眼镜，VR眼镜上设置有5个或7个扬声器和播放芯片(例如音频播放芯片)，在该播放芯片中内置有杜比音效算法。在佩戴VR眼镜并在观看视频时，手机通过USB Type C接口把音频信号传递给VR眼镜上设置的播放芯片。
在5.1声道音源并且VR眼镜上设置有5个扬声器的情况下，播放芯片完成5.1声道的算法处理，传递给5个扬声器5个声道的音源，5个扬声器播放各自声道的声音。图4是根据本公开实施例的实现多声道音效的VR眼镜的示意图。如图4所示，VR眼镜上设置有5颗扬声器，并且5颗扬声器按照前方、左前、右前、左后、右后的布局位置设置，最终达到高清晰度的立体声回放效果。这里，本领域技术人员可以理解的是，在VR眼镜设置有5个扬声器的情况下，也可以播放4.1声道音源、2.1声道音源、单声道音源等。
在7.1声道音源并且VR眼镜上设置有7个扬声器的情况下，播放芯片完成7.1声道的算法处理，传递给7个扬声器7个声道的音源，7个扬声器播放各自声道的声音。图5是根据本公开实施例的实现多声道音效的VR眼镜的示意图。如图5所示，VR眼镜上设置有7颗扬声器，并且该七颗扬声器按照左前、右前、前方、左侧、右侧、左后、右后的布局位置设置，最终达到超高清晰度的立体声回放效果。这里，可以理解的是，在VR眼镜设置有7个扬声器的情况下，也可以播放5.1声道音源、4.1声道音源、2.1声道音源、单声道音源等。
本公开的实施例还提供了一种通过VR眼镜实现4.1声道音效的方法，可以应用于图3所示的VR眼镜。图6是根据本公开实施例的通过VR眼镜实现4.1声道音效的方法的流程示意图。在本实施例中，假设VR眼镜包括两个扬声器并且与VR眼镜连接的手机也包括两个扬声器(如图3所示)，并且VR眼镜通过手机的耳机接口连通到手机电路上。如图6所示，所述方法可以包括以下步骤S601至S604。
在步骤S601，通过手机播放视频。
在步骤S602，通过手机扬声器单元播放音频信号。
在步骤S603，通过手机耳机通路播放音频信号。
在步骤S604，通过手机左扬声器、右扬声器以及VR眼镜左后扬声器、右后扬声器分别播放左前、右前、左后、右后四个声道的音源。
这里，扬声器单元指的是扬声器相关联的电路，例如，功放模块，转换电路等。
在本实施例中，可以在手机中集成杜比音效软件。在步骤S601中，在杜比音效软件中实现杜比4.1声道的音效处理。在步骤S602、S603中，将4声道的音源分别分配给手机扬声器单元和耳机接口(进而分配给VR眼镜的扬声器单元)。在步骤S604，手机扬声器单元完成左前、右前双声道播放；同时，VR眼镜的扬声器单元完成左后、右后双声道播放，最终完成4声道播放。
本实施例中提到的杜比音效软件，在视频播放时，利用杜比音效处理技术把视频中的音源解码成4声道的音源；同时控制手机耳机接口和扬声器通路同时打开，完成4声道的播放。
本实施例中的硬件实现框图请参考图7。图7是根据本公开实施例的实现4.1声道音效的硬件结构图。如图7所示，手机的顶部扬声器单元连接第一扬声器、手机的底部扬声单元连接第二扬声器，从而通过手机扬声器完成左前、右前双声道播放。另一方面，用于VR扬声器的音源信号通过模拟耳机通路(耳机接口)传输至第一VR扬声器单元和第二VR扬声器单元，其分别连接至第三扬声器和第四扬声器，从而通过VR扬声器实现左后、右后双声道播放。此外，如果VR眼镜上的扬声器单元附带功放模块，则需要同时使用USB线(或其他连接方式)连接手机与VR眼镜，从而使用手机的5V电压供电(例如，通过Vbus供电)给功放模块供电。
本公开的实施例提供了一种通过VR眼镜实现5.1声道音效的方法，可以应用于图4所示的VR眼镜。图8是根据本公开实施例的通过VR眼镜实现5.1声道音效的方法的流程示意图。在本实施例中，假设VR眼镜包括5个扬声器(如图4所示)。如图8所示，所述方法可以包括以下步骤S801至S803。
在步骤S801，通过手机播放视频。
在步骤S802，通过VR眼镜的播放芯片完成5.1声道音效处理，生成5声道音源；
在步骤S803，通过VR眼镜的5个扬声器完成5.1声道的5声道音源播放。
在本实施例，可以在手机中集成杜比音效软件，或者在VR眼镜的播放芯片中固化杜比音效算法。在视频播放时，可以通过手机中集成的杜比音效软件，利用杜比的音效处理技术对视频中的音源完成5.1声道的解码；同时通过VR眼镜的播放芯片把5声道音源分配给5个扬声器。
具体地，当在手机中集成杜比音效软件时，在步骤S801中，可以在杜比音效软件中完成杜比5.1声道音效处理，并通过例如Type C接口将处理后的音源数据传给VR眼镜。随后，在步骤S802，通过VR眼镜的播放芯片接收从手机传输的音源数据，并解析出5声道的音源码流。最后，在步骤S803，VR眼镜的播放芯片将5声道音源分别分 配给扬声器单元，完成左前、右前、前方、左后、右后5个声道的播放。
当在VR眼镜的播放芯片中集成杜比音效算法时，在步骤S801，手机通过例如Type C接口将音源数据传输给VR眼镜的播放芯片。随后，在步骤S802，在VR眼镜的播放芯片中实现杜比5.1声道的音效处理，生成5声道音源。最后，在步骤S803，VR眼镜的播放芯片将5声道音源分别分配给扬声器单元，完成左前、右前、前方、左后、右后5个声道的播放。
本实施例中多声道硬件实现框图请参考图9。图9是根据本公开实施例的实现多声道音效的硬件结构图。如图9所示，手机通过USB接口(例如，Type C接口)将音源数据传输至VR眼镜。此外，VR眼镜上的扬声器单元(分别与第一至第七扬声器以及更多的扬声器连接的第一至第七扬声器单元以及更多的扬声器单元)附带的功放模块(如有)以及播放芯片均可以通过USB接口(例如，通过Vbus)的5V电压供电。
需要提到的是，由于多声道需要用到多个扬声器单元且每个扬声器单元也需要相应的功放驱动，如果选用模拟功放，则需要增加一个多路模拟输出的DAC芯片，而选用数字功放，则只需要AP处理器(应用处理器)和多个数字功放即可实现相应功能。
本公开实施例还提供了一种通过VR眼镜实现7.1声道音效的方法，可以应用于图5所示的VR眼镜。图10是根据本公开实施例的通过VR眼镜实现7.1声道音效的方法的流程示意图。在本实施例中，假设VR眼镜包括7个扬声器(如图5所示)。如图10所示，所述方法可以包括以下步骤S1001至S1003。
在步骤S1001，通过手机播放视频。
在步骤S1002，通过VR眼镜的播放芯片完成7.1声道音效处理，生成7声道音源；
在步骤S1003，通过VR眼镜的7个扬声器完成7.1声道的7声道音源播放。
在本实施例，可以在手机中集成杜比音效软件，或者在VR眼镜 的播放芯片中固化杜比音效算法。在视频播放时，可以通过手机中集成的杜比音效软件，利用杜比的音效处理技术对视频中的音源完成7.1声道的解码；同时通过VR眼镜的播放芯片把7声道音源分配给7个扬声器。
具体地，当在手机中集成杜比音效软件时，在步骤S1001中，可以在杜比音效软件中完成杜比7.1声道的音效处理，并通过例如Type C接口将处理后的音源数据传给VR眼镜。随后，在步骤S1002，通过VR眼镜的播放芯片接收从手机传输的音源数据，并解析出7声道的音源码流。最后，在步骤S1003，VR眼镜的播放芯片将7声道音源分别分配给扬声器单元，完成左前、右前、前方、左侧、右侧、左后、右后7个声道的播放。
当在VR眼镜的播放芯片中集成杜比音效算法时，在步骤S1001，手机通过例如Type C接口将音源数据传输给VR眼镜的播放芯片。随后，在步骤S1002，在VR眼镜的播放芯片中实现杜比7.1声道的音效处理，生成7声道音源。最后，在步骤S1003，VR眼镜的播放芯片将7声道音源分别分配给扬声器单元，完成左前、右前、前方、左侧、右侧、左后、右后7个声道的播放。
本实施例中的多声道硬件实现框图也可以参考图9。手机通过USB接口(例如，Type C接口)将音源数据传输至VR眼镜。此外，VR眼镜上的扬声器单元附带的功放模块(如有)以及播放芯片均可以通过USB接口(例如，通过Vbus)的5V电压供电。
