Description

音频数据的处理方法、装置及音箱系统
本申请要求于2020年08月27日提交国家知识产权局、申请号为202010880205.9、申请名称为“音频数据的处理方法、装置及音箱系统”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
本申请实施例涉及音频技术领域，尤其涉及一种音频数据的处理方法、装置及音箱系统。
背景技术
随着音频软硬件技术的发展，音频播放设备(例如全频音箱)层出不穷，音频播放设备的一个重要的性能指标是音频播放设备的音质。
目前，对于现有的各类全频音箱产品，无法较好的兼顾全频音箱的便携性和全频音箱的音质。例如，对于小体积、小质量、便携性较好的全频音箱，由于全频音箱的音腔体积较小，低音音质受到影响，因此音质较差。又例如，对于音质较好的全频音箱，由于全频音箱内集成的音频单元(包括中高频/全频扬声器以低频扬声器)较多，因此全频音箱的体积、重量和功耗等较大，且便携性较差。
基于此，对便携且音质优越的全频音箱产品研发是需要攻克的难题。
发明内容
本申请实施例提供一种音频数据的处理方法、装置及音箱系统，能够提升音频播放设备的音质。
为达到上述目的，本申请实施例采用如下技术方案：
第一方面，本申请实施例提供一种全频音箱，包括全频音箱主体和第一固定部件；该全频音箱主体包括M个扬声器，该M个扬声器在全频音箱主体中成平面分布，M个扬声器构成K对声偶极子，M为大于2的正整数，K为大于或等于2的正整数。第一固定部件设置于全频音箱主体的预设固定区域，该第一固定部件用于与低频音箱进行物理连接或拆卸，第一固定部件中包括第一通信部件，第一通信部件用于使得全频音箱与低频音箱通信，第一通信部件支持传输多声道音频数据。其中，低频音箱的低频播放效果优于全频音箱的低频播放效果。
本申请实施例提供的全频音箱，由于该全频音箱中包含的M个扬声器构成多对声偶极子，通过该全频音箱播放经声场扩展处理的音频数据(即目标音频数据)能够获取较好的声场扩展效果，提升音质。进一步的，通过该全频音箱上的第一固定部件与低频音箱连接后，全频音箱与低频音箱组合使用以播放音频数据，能够显著提升音频数据的播放效果，并且用户可灵活选择使用全频音箱播放音频数据，或者使用全频音箱和低频音箱播放音频数据，能够满足用户的不同需求。
一种可能的实现方式中，M个扬声器构成的K对声偶极子的排布方向至少包括水平、竖直或斜上中的至少两种方向。
即K对声偶极子至少包括水平方向的声偶极子、竖直方向的声偶极子或斜上方向 的声偶极子中的至少两种声偶极子。上述水平方向指的是与全频音箱主体的垂直投影所平行的方向，上述竖直方向是与与全频音箱主体的垂直投影所垂直的方向。上述斜上方向可以包括多种不同的预设方向，不同的预设方向与水平方向的夹角不同，此处的预设方向可以理解为以不同的角度指向天空的方向(简称为天空方向)。
一种可能的实现方式中，每一对声偶极子对应一对扬声器，上述K对声偶极子中的至少两对声偶极子满足下述条件：d i≠d j；其中，d i是构成第i对声偶极子的两个扬声器之间的距离，d j是构成第j对声偶极子的两个扬声器对之间的距离，i和j分别为1，2，……，K中的一个值，且i≠j，K为大于或等于2的正整数。其中，构成第i对声偶极子的两个扬声器用于播放目标音频数据的第一频段，构成第j对声偶极子的两个扬声器用于播放目标音频数据的第二频段，第一频段与第二频段是不同的频段。
一种可能的实现方式中，若d i＞d j，则构成第i对声偶极子的两个扬声器所能播放的音频数据的中心频率小于构成第j对声偶极子的两个扬声器所能播放的音频数据的中心频率。
本申请实施例中，构成一对声偶极子的扬声器对所播放的音频数据的频段与扬声器对包含的两个扬声器之间的距离有关。具体的，构成一对声偶极子的两个扬声器播放的音频数据的中心频率随着扬声器之间的距离的增大而减小。对于距离较小的扬声器对，该扬声器对播放高频带的音频数据的效果较好。
通过调整全频音箱的扬声器的布局，使得构成多对声偶极子的扬声器对的两个扬声器之间的间距相同或者不同。通过不同间距的扬声器对播放不同频带的音频数据，能够营造不同频段的声场效果。

本申请实施例提供的音频数据的处理方法，上述全频音箱完成对音频数据的声场扩展处理之后，一方面，该全频音箱播放经声场扩展处理后的音频数据的高频分量和/或中频分量，由于全频音箱对中频和高频具有较好的播放效果，因此能够提升中频分量和/或高频分量的音质。另一方面，全频音箱向低频音箱发送经声场扩展处理后的音频数据的低频分量，由低频音箱播放该低频分量，由于低频音箱的低频播放效果优于全频音箱的低频播放效果，因此能够提升音频数据的低音音质。

一种可能的实现方式中，上述声场扩展处理包括：全频音箱对滤波后的音频数据的高频分量进行高频带偶极子处理，和/或对滤波后的音频数据的中频分量进行中频带偶极子处理。
可以理解的是，全频音箱的扬声器的声场存在甜点(sweet point)区域，该甜点区域指的是能够达到较好的音效的区域，通常该甜点区域是与全频音箱中心偏离预设角度的区域。当用户(或听音者)位于甜点区域内时，用户具有较好的听音感受；当用户远离甜点区域(例如用户与全频音箱中心的之间的夹角的角度大于上述预设角度)时，将出现双耳串扰的现象，如此，用户的听音感受将变差。
本申请实施例中，一对声偶极子对应一对扬声器，通过一对扬声器播放幅度相同， 相位不同的信号。以水平方向为例，右声道对应一个声偶极子，左声道对应一个声偶极子，例如，当右声道信号到达用户的左耳的能量较大时，左右耳将出现串扰，即右声道信号对左耳形成干扰，如此，声场变窄。当右声道信号达到用户的左耳的能量较小时，左右耳串扰较小。
本申请实施例中，采用高频带偶极子算法对音频数据的高频分量进行声场扩展处理，采用中频带偶极子算法对音频数据的中频分量进行声场扩展处理，对于右声道信号，能够在保证右声道信号到达右耳的能量不降低的情况下，减小右声道信号到达左耳的能量；对于左声道信号，能够在保证左声道信号到达左耳的能量不降低的情况下，减小左声道信号到达右耳的能量，从而实现双耳串扰消除。本申请实施例中，右声道信号到达用户的左耳的能量越小，该右声道信号到达用户的右耳的能量越大，则双耳串扰消除效果越好；同理，左声道信号到达右耳的能量越小，该左声道信号到达左耳的能量越大，则双耳串扰消除效果越好。
一种可能的实现方式中，上述声场扩展处理包括：采用低音增强算法对滤波后的音频数据的低频分量进行处理，在不损伤扬声器的情况下(不超过振膜最大位移)，动态提升低频信号(即低频分量)的能量，显著提升音频数据的低音音质。应理解，低音增强算法通过预先获得扬声器的参数(TS参数)，并根据扬声器的参数建模，得到的处理模型。
一种可能的实现方式中，一种频带对应一对或多对声偶极子。例如，高频带对应多对声偶极子，如此，通过高频滤波后的高频分量经高频带偶极子算法处理后，将通过多对偶极子对应的扬声器播放。

本申请实施例中，上述低频音箱完成对音频数据的声场扩展处理之后，一方面，通过该低频音箱上的低音扬声器播放低音增强处理后的低频分量，由于低频音箱的低频播放效果优于全频音箱的低频播放效果，因此能够提升音频数据的低音音质。另一方面，该低频音箱向全频音箱发送经声场扩展处理后的音频数据的高频分量和/或中频分量，进而由全频音箱播放该高频分量和/或中频分量，由于全频音箱对中频和高频具有较好的播放效果，因此能够提升中频分量和/或高频分量的音质。
一种可能的实现方式中，本申请实施例提供的音频数据的处理方法还包括：通过低频音箱上的摄像头采集听音者的图像信息，或者通过麦克风采集听音者的声音信号， 该听音者的图像信息或听音者的声音信号用于对滤波后的待播放的音频数据进行声场扩展处理。具体的，低频音箱对听音者的图像信息或声音信号进行分析，确定听音者的位置信息，用户的位置信息包括用户与音箱系统的中心轴的夹角的角度。并且根据听音者的位置信息，调整组成一对声偶极子的两个扬声器播放信号的相位差，该相位差是高频带偶极子处理和/或中频带偶极子处理的配置参数。
本申请实施例中，为提升用户的听音感受，在对音频数据进行声场扩展的过程中，可以调整高频带偶极子算法或中频带偶极子算法中的配置参数(即配置参数即为组成一对声偶极子的两个扬声器播放信号的相位差)，从而提升双耳串扰消除的效果，使得用户在当前位置处达到较好的听音感受。具体的，由于该相位差与用户当前的位置有关，因此通过上述步骤A至步骤C调整上述相位差，如此采用该调整后的相位差对音频数据进行声场扩展处理，消除双耳串扰，达到在用户当前位置处进行声场扩展的效果，实时提升用户的听音感受。

图2示例了几种形状的全频音箱主体的正视图，其中，图2中的(a)为环形全频 音箱(即Sound Ring)，上述M个扬声器部署在圆环内；图2中的(b)为圆形全频音箱，上述M个扬声器部署在圆面上；图2中的(c)为树形全频音箱，图2中的(d)为W型全频音箱。本申请实施例中，M个扬声器排布在全频音箱主体的一个平面上，即M个扬声器是共平面的，且朝向该全频扬声器的同一表面。
本申请实施例中，上述第一固定部件还用于支撑全频音箱主体。例如，如图3所示，当全频音箱主体为环形时，该第一固定部件可以作为底座以支撑该环形音箱主体，使其稳定地置于桌面上。
本申请实施例中，上述全频音箱的M个扬声器构成K对声偶极子，其中，一对声偶极子对应一对声扬声器。例如，对于图2中的(a)所示的环形全频音箱，该环形全频音箱包含8个扬声器，其中，扬声器1和扬声器5构成一对声偶极子，扬声器2和扬声器4构成一对声偶极子，扬声器6和扬声器8构成一对声偶极子，扬声器3和扬声器7构成一对声偶极子。
应理解，上述全频音箱中的扬声器构成的K对声偶极子的排布方向至少包括水平、竖直或斜上中的至少两种方向，即K对声偶极子至少包括水平方向的声偶极子、竖直方向的声偶极子或斜上方向的声偶极子中的至少两种声偶极子。结合图3，上述水平方向指的是与全频音箱主体的垂直投影所平行的方向，上述竖直方向是与与全频音箱主体的垂直投影所垂直的方向。仍以全频音箱为图2中的(a)所示的环形全频音箱为例，在该环形全频音箱中，扬声器1和扬声器5构成一对水平方向的声偶极子，扬声器3和扬声器7构成一对竖直方向的声偶极子。
本申请实施例中，上述预设方向与的夹角，此处的预设方向可以理解为以不同的角度指向天空的方向(简称为天空方向)，例如，图4中的(a)示意的与第一方向的夹角小于180度的方向是天空方向。示例性的，如图4中的(b)所示的环形全频音箱中，虚线框内的两个扬声器构成天空方向的声偶极子。为了便于描述，本申请实施例中，将其他预设方向的声偶极子统一称为天空方向的声偶极子。
本申请实施例中，全频音箱播放的目标音频数据是对原始音频数据进行声场扩展处理后的音频数据，应注意，声场扩展处理后的音频数据与全频音箱的不同方向的偶极子是相对应的。例如，构成水平方向的声偶极子的扬声器对用于播放经水平方向进行声场扩展处理后的音频数据，构成竖直方向的声偶极子的扬声器对用于播放经竖直方向进行声场扩展处理后的音频数据，构成天空方向的声偶极子的扬声器对用于播放经天空方向进行声场扩展后的音频数据。对音频数据做竖直方向的声场扩展以及其他预设方向的声场扩展，能够提升音频数据回放的3D效果。在本申请实施例中，声场扩展包括对音频数据的高频分量进行高频带偶极子处理、对音频数据的中频分量进行中频带偶极子处理以及对音频数据的低频分量的低音增强处理，具体将在下述方法实施例中详述。
可选地，本申请实施例对全频音箱包含的扬声器的数量M也不作限定，具体根据实际需求设定。例如，在一种实现方式中，本申请实施例提供的全频音箱包括6个扬声器或8个扬声器。
本申请实施例提供的全频音箱对播放音频数据的中频分量和高频分量具有较好的播放效果，上述M个扬声器中的一个或多个扬声器为全频扬声器，或者，该M个扬 声器中的一个或多个扬声器为中高频扬声器，本申请实施例不作限定。例如，该全频音箱包含8个扬声器，其中，该8个扬声器可以全部为全频扬声器，或者，该8个扬声器中的4个扬声器为全频扬声器，4个扬声器为中高频扬声器。
在一种实现方式中，本申请实施例提供的全频音箱中的M个扬声器构成K对声偶极子，一对声偶极子对应一对扬声器，该K对声偶极子中的至少两对声偶极子满足下述条件：d i≠d j。其中，d i是构成第i对声偶极子的两个扬声器之间的距离，d j是构成第j对声偶极子的两个扬声器对之间的距离，i和j分别为1，2，……，K中的一个值，且i≠j，K为大于或等于2的正整数。并且构成第i对声偶极子的两个扬声器播放目标音频数据的第一频段，构成第j对声偶极子的两个扬声器播放目标音频数据的第二频段，第一频段与第二频段是不同的频段。
应理解，构成一对声偶极子的扬声器对所播放的音频数据的频段与扬声器对包含的两个扬声器之间的距离有关。具体的，构成一对声偶极子的两个扬声器播放的音频数据的中心频率随着扬声器之间的距离的增大而减小。若上述d i＞d j，则构成第i对声偶极子的两个扬声器所能播放的音频数据的中心频率小于构成第j对声偶极子的两个扬声器所能播放的音频数据的中心频率。
例如，构成第i对声偶极子的扬声器对播放的音频数据的频段可以为600Hz-2600Hz，构成第j对声偶极子的扬声器对播放的音频数据的频段可以为2600Hz-12KHz。对于距离较小的一个扬声器对，该扬声器对播放高频带的音频数据的效果较好。
本申请实施例中，通过调整全频音箱的扬声器的布局，使得构成多对声偶极子的扬声器对的两个扬声器之间的间距相同或者不同。通过不同间距的扬声器对播放不同频带的音频数据，能够营造不同频段的声场效果。
示例性的，图5示意了环形全频音箱的扬声器的两种不同的布局，如图5中的(a)所示，该环形全频音箱包含4对不同间距的水平方向的声偶极子，其中，扬声器1和扬声器4构成第一对水平方向的声偶极子，扬声器8和扬声器5构成第二对水平方向的声偶极子，扬声器2和扬声器3构成第三对水平方向的声偶极子，扬声器7和扬声器6构成第四对水平方向的声偶极子。图5中的(b)所示的环形全频音箱包含2对水平方向的声偶极子和2对竖直方向的声偶极子，其中，扬声器1和扬声器3构成一对远距离的水平方向的声偶极子，扬声器5和扬声器4构成一对近距离的水平方向的声偶极子；扬声器5和扬声器2构成一对远距离的竖直方向的声偶极子，扬声器5和扬声器6构成一对近距离的竖直方向的声偶极子。
基于上述实施例的描述，由于扬声器对播放的音频数据的中心频率随着扬声器对包含的两个扬声器之间的距离的增大而减小，因此，结合图5中的(a)，上述构成4对水平方向的声偶极子的4个扬声器对播放的音频数据的中心频率依次升高，即第一对水平方向的声偶极子对应的音频数据的中心频率最小，依次类推，第四对水平方向的声偶极子对应的音频数据的中心频率最高。
可选地，本申请实施例中，一个扬声器可以被复用于一对或多对声偶极子中。例如，结合图4中的(b)，扬声器5和扬声器4构成一对水平方向的声偶极子，扬声器5和扬声器2构成一对竖直方向的声偶极子，且扬声器5和扬声器6构成另一对竖直方向的声偶极子，可见，扬声器5被复用于多对声偶极子中。

如图17所示，本申请实施例提供一种音频数据的处理方法，应用于上述全频音箱，该方法包括步骤1701至步骤1704。
步骤1701、全频音箱获取待播放的音频数据。
应理解，上述待播放的音频数据是原始音频数据。可选地，该待播放的音频数据可以是全频音箱从终端接收的音频数据，或者是该全频音箱从其他设备获取的音频数据，本申请实施例不作限定。
步骤1702、全频音箱对获取的待播放的音频数据进行多频带滤波，得到待播放的音频数据的中频分量和/或高频分量，以及低频分量。
可选地，本申请实施例中，上述多频带滤波可以包括高频滤波、带通滤波以及低频滤波。和/或，多频带滤波包括高频滤波和低频滤波。应理解，对音频数据进行高频滤波，得到音频数据的高频分量；对音频数据进行带通滤波，得到音频数据的中频分量；对音频数据进行低频滤波，得到音频数据的低频分量。
需要说明的是，本申请实施例中，对音频数据进行多频带滤波时，滤波频带的设置与全频音箱中组成偶极子的扬声器对中的两个扬声器之间的距离有关。滤波频带决定滤波后的高频分量、中频分量以及低频分量各自对应的频段。
步骤1703、全频音箱对待播放的音频数据的中频分量和/或高频分量，以及低频分量进行声场扩展处理，得到目标音频数据。
上述步骤1703包括步骤1703a至步骤1703b。
步骤1703a、全频音箱对滤波后的音频数据的高频分量进行高频带偶极子处理，和/或对滤波后的音频数据的中频分量进行中频带偶极子处理。
可以理解的是，全频音箱的扬声器的声场存在甜点(sweet point)区域，该甜点区域指的是能够达到较好的音效的区域，通常该甜点区域是与全频音箱中心偏离预设角度的区域。当用户(或听音者)位于甜点区域内时，用户具有较好的听音感受；当用户远离甜点区域(例如用户与全频音箱中心的之间的夹角的角度大于上述预设角度)时，将出现双耳串扰的现象，如此，用户的听音感受将变差。
本申请实施例中，一对声偶极子对应一对扬声器，通过一对扬声器播放幅度相同，相位不同的信号。以水平方向为例，右声道对应一个声偶极子，左声道对应一个声偶极子，例如，当右声道信号到达用户的左耳的能量较大时，左右耳将出现串扰，即右 声道信号对左耳形成干扰，如此，声场变窄。当右声道信号达到用户的左耳的能量较小时，左右耳串扰较小。
本申请实施例中，采用高频带偶极子算法对音频数据的高频分量进行声场扩展处理，采用中频带偶极子算法对音频数据的中频分量进行声场扩展处理，对于右声道信号，能够在保证右声道信号到达右耳的能量不降低的情况下，减小右声道信号到达左耳的能量；对于左声道信号，能够在保证左声道信号到达左耳的能量不降低的情况下，减小左声道信号到达右耳的能量，从而实现双耳串扰消除。本申请实施例中，右声道信号到达用户的左耳的能量越小，该右声道信号到达用户的右耳的能量越大，则双耳串扰消除效果越好；同理，左声道信号到达右耳的能量越小，该左声道信号到达左耳的能量越大，则双耳串扰消除效果越好。
通过偶极子算法处理之后，偶极子的指向性发生改变，图18为右声道对应的偶极子的指向性图，通过该偶极子的指向性图可以进一步展示串扰消除的效果。该右声道对应的声偶极子的指向性图可以通过下述公式表示：
Figure PCTCN2021103324-appb-000001
其中，w＝2πf，f为右声道信号的频率，t delay是偶极子对应的扬声器播放的信号达到左耳与右耳的时间差，d spk是构成一对声偶极子的两个扬声器之间的距离，
Figure PCTCN2021103324-appb-000002
为指向性图的遍历角度，θ为偶极子处理算法中的配置参数，该配置参数为组成一对声偶极子的两个扬声器播放信号的相位差，c为声速。该相位差θ与用户的位置相关，具体的，可根据用户位置调整θ以达到最优的串扰消除，即声场扩展效果。
以图18中的(a)为例，需要说明的是，圆周上的角度是
Figure PCTCN2021103324-appb-000003
(0度至360度)，不同的圆周对应不同的能量(例如0.5，1，1.5，2)。其中，图18中的(a)示意的是θ为0度时该偶极子的指向性图，结合该指向性图可知，此时右声道信号达到左耳的能量较小，该右声道信号到达右耳的能量较大。具体的，图18中的(a)中，用户位于全频音箱的正前方(270度方向)，假设用户的左耳与全频音箱中心的夹角为30度，则图中240度方向是用户左耳所在的方向，并且此时对应的θ为0度，可见在240度附近，右声道信号达到左耳的能量较小。且在240度附近，右声道信号到达右耳的能量较大。
图18中的(b)示意的是θ为30度时该偶极子的指向性图，图18中的(c)示意的是θ为-30度时该偶极子的指向性图。同理，此时右声道信号达到左耳的能量较小，该右声道信号到达右耳的能量较大。
可选地，本申请实施例中，一种频带对应一对或多对声偶极子。例如，高频带对应多对声偶极子，如此，通过高频滤波后的高频分量经高频带偶极子算法处理后，将通过多对偶极子对应的扬声器播放。
步骤1703b、对滤波后的音频数据的低频分量进行低音增强处理。
本申请实施例中，采用低音增强算法对滤波后的音频数据的低频分量进行处理，在不损伤扬声器的情况下(不超过振膜最大位移)，动态提升低频信号(即低频分量)的能量，显著提升音频数据的低音音质。
应理解，低音增强算法通过预先获得扬声器的参数(TS参数)，并根据扬声器的 参数建模，得到的处理模型，具体可以参考现有方法，本申请实施例不再赘述。
可选地，全频音箱对原始音频数据处理之后，得到目标音频数据(具体包括目标音频数据的中频分量和/或高频分量，以及低频分量)该目标音频数据的中频分量和/或高频分量由全频音箱播放。
步骤1704、全频音箱向低频音箱发送目标音频数据的低频分量。
如此，目标音频数据的低频分量由低频音箱播放，该低频音箱的低频播放效果优于全频音箱的低频播放效果。
在一种实现方式中，全频音箱也可以不向低频音箱发送目标音频数据的低频分量，而是由该全频音箱播放该目标音频数据(包括中频分量和/或高频分量，以及低频分量)。
本申请实施例提供的音频数据的处理方法，上述全频音箱完成对音频数据的声场扩展处理之后，一方面，该全频音箱播放经声场扩展处理后的音频数据的高频分量和/或中频分量，由于全频音箱对中频和高频具有较好的播放效果，因此能够提升中频分量和/或高频分量的音质。另一方面，全频音箱向低频音箱发送经声场扩展处理后的音频数据的低频分量，由低频音箱播放该低频分量，由于低频音箱的低频播放效果优于全频音箱的低频播放效果，因此能够提升音频数据的低音音质。
如图19所示，本申请实施例提供一种音频数据的处理方法，应用于低频音箱，该方法包括步骤1901至步骤1904。
步骤1901、低频音箱获取待播放的音频数据。
应理解，上述待播放的音频数据是原始音频数据。可选地，该待播放的音频数据可以是低频音箱从终端接收的音频数据，或者是该低频音箱从其他设备获取的音频数据，本申请实施例不作限定。

步骤1903、低频音箱对待播放的音频数据的中频分量和/或高频分量，以及低频分量进行声场扩展处理，得到目标音频数据。
需要说明的是，该低频音箱对待播放的音频数据进行多频带滤波、声场扩展处理的方法与上述全频音箱对待播放的音频数据进行多频带滤波以及声场扩展处理的方法相同，具体可参考上述实施例的描述，此处不再赘述。
步骤1904、低频音箱向全频音箱发送目标音频数据的中频分量和/或高频分量。
本申请实施例中，上述低频音箱完成对音频数据的声场扩展处理之后，一方面，通过该低频音箱上的低音扬声器播放低音增强处理后的低频分量，由于音频数据的低频分量是由低频音箱中专用的低频扬声器播放，因此能够提升音频数据的低音音质。另一方面，该低频音箱向全频音箱发送经声场扩展处理后的音频数据的高频分量和/或中频分量，进而由全频音箱播放该高频分量和/或中频分量，由于全频音箱对中频和高频具有较好的播放效果，因此能够提升中频分量和/或高频分量的音质。
