处理器151可以是任何常规的处理器，诸如商业可获得的CPU。替选地，处理器151还可以包括诸如图像处理器(graphic process unit，GPU)，现场可编程门阵列(field programmable gate array，FPGA)、片上***(system on chip，SOC)、专用集成芯片(application specific integrated circuit，ASIC)或它们的组合。尽管图1功能性地图示了处理器、存储器、和在相同块中的计算机110的其它元件，但是本领域的普通技术人员应该理解该处理器、计算机、或存储器实际上可以包括可以或者可以不存储在相同的物理外壳内的多个处理器、计算机、或存储器。例如，存储器可以是硬盘驱动器或位于不同于计算机110的外壳内的其它存储介质。因此，对处理器或计算机的引用将被理解为包括对可以或者可以不并行操作的处理器或计算机或存储器的集合的引用。不同于使用单一的处理器来执行此处所描述的步骤，诸如转向组件和减速组件的一些组件每个都可以具有其自己的处理器，所述处理器只执行与特定于组件的功能相关的计算。
在此处所描述的各个方面中，处理器可以位于远离该车辆并且与该车辆进行无线通信。在其它方面中，此处所描述的过程中的一些在布置于车辆内的处理器上执行而其它则由远程处理器执行，包括采取执行单一操纵的必要步骤。
在一些实施例中，存储器152可包含指令153(例如，程序逻辑)，指令153可被处理器151执行来执行车辆100的各种功能。存储器152也可包含额外的指令，包括向信息娱乐***110、感知***120、决策控制***130驱动***140中的一个或多个发送数据、从其接收数据、与其交互和/或对其进行控制的指令。

在道路行进的自动驾驶汽车，如上面的车辆100，可以识别其周围环境内的物体以确 定对当前速度的调整。所述物体可以是其它车辆、交通控制设备、或者其它类型的物体。在一些示例中，可以独立地考虑每个识别的物体，并且基于物体的各自的特性，诸如它的当前速度、加速度、与车辆的间距等，可以用来确定自动驾驶汽车所要调整的速度。
可选地，车辆100或者与车辆100相关联的感知和计算设备(例如计算***131、计算平台150)可以基于所识别的物体的特性和周围环境的状态(例如，交通、雨、道路上的冰、等等)来预测所述识别的物体的行为。可选地，每一个所识别的物体都依赖于彼此的行为，因此还可以将所识别的所有物体全部一起考虑来预测单个识别的物体的行为。车辆100能够基于预测的所述识别的物体的行为来调整它的速度。换句话说，自动驾驶汽车能够基于所预测的物体的行为来确定车辆将需要调整到(例如，加速、减速、或者停止)什么稳定状态。在这个过程中，也可以考虑其它因素来确定车辆100的速度，诸如，车辆100在行驶的道路中的横向位置、道路的曲率、静态和动态物体的接近度等等。
除了提供调整自动驾驶汽车的速度的指令之外，计算设备还可以提供修改车辆100的转向角的指令，以使得自动驾驶汽车遵循给定的轨迹和/或维持与自动驾驶汽车附近的物体(例如，道路上的相邻车道中的轿车)的安全横向和纵向距离。
上述车辆100可以为轿车、卡车、摩托车、公共汽车、船、飞机、直升飞机、割草机、娱乐车、游乐场车辆、施工设备、电车、高尔夫球车、火车等，本申请实施例不做特别的限定。
随着人民生活水平的提高，车辆已经成为人们出行的重要交通工具。在车辆行驶或者等待的时候，人们喜欢听听音乐和广播，有时候还会看看电影，刷刷短视频。因此，车内的声场效果已经成为大家关注的重要因素，好的声音效果总能给人带来舒适的体验。
当前用户需要通过手动调节来控制各个扬声器的播放强度，从而达到目标点位置的声场最优。如果需要驾驶员手动去调节，就需要驾驶员的视线转移到屏幕上。这对于驾驶来说，存在一定安全隐患。与此同时，当车内乘客换位置或者数量增加的时候，需要不断的去手动调节各个扬声器的播放强度，这样会导致用户的体验不好。
本申请实施例提供了一种发声装置的控制方法、发声***以及车辆，通过识别用户所在的区域的位置信息，自动调节声场优化中心，从而使得每一个用户都能达到一个好的听音效果。
下面通过图2和图3介绍本申请实施例提供车载发声***。图2示出了本申请实施例提供的一种发声***的结构示意图。该发声***可以为控制器局域网络(controller area network，CAN)控制***，该CAN控制***可以包括多个传感器(例如，传感器1、传感器2等)，多个电子控制单元(electronic control unit，ECU)、车载娱乐主机、扬声器控制器以及扬声器。其中，传感器包括但不限于摄像头、麦克风、超声波雷达、毫米波雷达、激光雷达、车速传感器、电机功率传感器以及发动机转速传感器等；ECU用于接收传感器采集的数据并执行相应命令，在执行相应命令后得到周期信号或者事件信号，进而ECU可以将这些信号发到公CAN网络上，其中ECU包括但不限于整车控制器、混合动力控制器、自动变速箱控制器以及自动驾驶控制器等；车载娱乐主机用于抓取公CAN网络上的各个ECU发出的周期信号或者事件信号，在识别到对应的信号状态下执行相应的操作或者转发信号给扬声器控制器；扬声器控制器用于收取私CAN网络上来自车载娱乐主机的命令信号，对扬声器进行调节。示例性的，本申请实施例中，车载娱乐主机可以从 CAN总线上抓取摄像头采集的图像信息。车载娱乐主机可以通过图像信息判断车内多个区域中是否存在用户，并将用户的位置信息发送给扬声器控制器。扬声器控制器可以根据用户的位置信息，控制各个扬声器的播放强度。
图3示出了本申请实施例提供的一种车内发声***的另一结构示意图。该发声***可以为环网通信架构，所有传感器与执行器(例如，扬声器、氛围灯、空调、电机等得到命令并执行命令的部件)可以就近接入车辆集成单元(vehicle integration unit，VIU)。其中，VIU作为通信接口单元，可以部署于车辆传感器与执行器密集位置，使得车辆的传感器与执行器可以进行就近接入；同时，VIU可以具备一定计算与驱动能力(例如，VIU可以吸纳部分执行器的驱动计算功能)；传感器包括但不限于摄像头、麦克风、超声波雷达、毫米波雷达、激光雷达、车速传感器、电机功率传感器以及发动机转速传感器等。
VIU之间相互向组网通信，智能驾驶计算平台/移动数据中心(mobile data center，MDC)、整车域控制器(vehicle domain controller，VDC)以及智能座舱域控制器(cockpit domain controller，CDC)分别冗余接入由VIU组成的环网通信网络。当传感器(例如，摄像头)采集到数据后，传感器可以将采集的数据发送给VIU。VIU可以将数据发布到环网上，由MDC、VDC以及CDC在环网上收集相关数据，加以计算后转化为包括用户位置信息的信号并发布到环网上。通过VIU中相应的计算能力以及驱动能力，控制扬声器的播放强度。
应理解，如图3所示，不同的VIU可以与不同位置的扬声器具有对应关系。例如，VIU1用于驱动扬声器1，VIU2用于驱动扬声器2，VIU3用于驱动扬声器3，VIU4用于驱动扬声器4。VIU的布置形式可以是与扬声器无关，例如，VIU1可以布置于车辆的左后方，而扬声器1可以布置于主驾侧的车门附近。传感器或者执行器可以选择就近的VIU接入，从而节省线束。由于MDC、VDC以及CDC的接口数量的限制，可以由VIU来承担多个传感器以及多个执行器的接入，从而起到接口和通信的功能。
还应理解，本申请实施例中，传感器或者控制器在哪一个VIU接入、由哪一个控制器控制可以是发声***出厂时设定好的，或者，也可以是由用户定义的，其硬件可更换可升级。
还应理解，VIU可以吸纳部分传感器与执行器的驱动计算功能，这样当某些执行器(例如，CDC、VDC)发生故障时，VIU可以直接对传感器采集的数据进行处理，进而对执行器进行控制。
一个实施例中，图3所示的通信架构可以是智能数字汽车平台(intelligent digital vehicle platform，IDVP)环网通信架构。
图4示出了一种车辆的俯视图。如图4所示，位置1为主驾位，位置2为副驾位，位置3-5为后排区域，位置6a-6d为车内的4个扬声器所在的位置，位置7为车内摄像头所在的位置，位置8为CDC以及车载中控屏所在的位置。其中，扬声器可以用于播放车内的媒体声音；车内摄像头可以用于检测车内乘客的位置；车载中控屏可以用于显示图像信息以及应用程序的界面；CDC用于连接各个外设，同时提供数据的分析和处理能力。
应理解，图4中仅仅是以位置6a-6d所示的扬声器分别位于主驾位车门附近、副驾位车门附近、二排左侧车门附近以及二排右侧车门附近为例进行说明的。本申请实施例中，对于扬声器的位置并不作具体限定。扬声器也可以位于车辆的车门附近、中控大屏附近、 顶棚、地板以及座椅(例如，座椅的枕头上)。
图5示出了本申请实施例提供的发声装置的控制方法500的示意性流程图。该方法500可以应用于车辆中，该车辆中包括多个发声装置(例如，扬声器)，该方法500包括：
S501，车辆获取用户的位置信息。
一个实施例中，车辆可以通过启动车内摄像头来获取车内各个区域(例如主驾位、副驾位以及后排区域)的图像信息，并通过各个区域中的图像信息来确定各个区域中是否有用户。例如，车辆可以通过摄像头采集的图像信息分析其中包含人脸的轮廓，从而车辆可以确定该区域中是否存在用户。又例如，车辆可以通过摄像头采集的图像信息分析其中包含人眼的虹膜信息，从而车辆可以确定该区域中存在用户。
一个实施例中，当车辆检测到用户打开声场自适应开关的操作时，车辆可以启动摄像头来获取车内各个区域的图像信息。
示例性的，用户可以通过中控大屏选择设置选项并进入音效功能界面，在音效功能界面可以选择打开声场自适应开关。
一个实施例中，车辆还可以通过座椅下的压力传感器来检测当前区域中是否存在用户。示例性的，当某个区域的座椅上的压力传感器检测到的压力值大于或者等于预设值时，可以确定该区域中存在用户。
一个实施例中，车辆还可以通过麦克风阵列获取的音频信息来确定声源位置信息，从而可以确定哪些区域中存在用户。
一个实施例中，车辆获取车内用户的位置信息还可以通过上述车内摄像头、压力传感器以及麦克分阵列中的一种或者多种的组合来实现。
应理解，本申请实施例中传感器(例如，车内摄像头、压力传感器或者麦克风阵列)采集的数据可以传输至CDC，CDC可以通过对数据进行处理来确定哪些区域中存在用户。
示例性的，CDC在对数据进行处理后可以将其转化为标示位，例如，当仅有主驾位有人时CDC可以输出1000；当仅有副驾位有人时CDC可以输出0100；当仅有二排左侧区域有人时CDC可以输出0010；当主驾位和副驾位都人时CDC可以输出1100；当主驾位、副驾位和二排左侧有人时可以输出1110。
应理解，上述CDC输出的位置信息的方式仅仅是以标示位为例进行说明的，本申请实施例并不限于此。
还应理解，上述对车内用户乘坐的区域划分为主驾位、副驾位、二排左和二排右为例进行说明的。本申请实施例并不限于此。例如，也可以将车内区域划分为主驾位、副驾位、二排左、二排中和二排右；又例如，对于7座SUV，还可以将车内区域划分为主驾位、副驾位、二排左、二排右、三排左和三排右。又例如，对于客车而言，可以将车内区域划分为前排区域和后排区域。或者，对于多人客车而言，可以将车内的区域划分为驾驶区域，乘客区域等。
S502，车辆根据用户的位置信息，对发声装置进行调节。
示例性的，以发声装置为扬声器为例，结合图2中的扬声器6a-6d进行说明。图6示出了4个扬声器的位置。以4个扬声器所在的点的连线形成的图形是矩形ABCD为例，该矩形ABCD上的A点设置有扬声器1，B点设置有扬声器2，C点设置有扬声器3以及D点设置有扬声器4。O点为矩形ABCD的中心点(O点到A、B、C、D四个点的距 离相等)。应理解的是，不同汽车的扬声器位置和数量不同，在具体实施过程中，可以根据汽车的型号或汽车中扬声器的设置，来设计具体的调节方式，本申请不作限定。
图7示出了本申请实施例提供的当主驾位、副驾位、二排左侧和二排右侧区域均有用户时车内扬声器的声场优化中心的示意图。每个区域的中心点可以组成一个矩形EFGH，矩形EFGH的中心点可以为Q点。Q点可以为当前车内的声场优化中心点。
示例性的，Q点可以是和O点重合。由于矩形EFGH的中心点Q距离四个扬声器的距离是相等的，那么此时车辆可以控制四个扬声器的播放强度相同(例如，4个扬声器的播放强度均为p)。
示例性的，若Q点和O点不重合，则车辆可以根据Q点距离4个扬声器的距离来控制4个扬声器的播放强度。
例如，对于扬声器1(位于A点)，车辆可以控制扬声器1的播放强度为

又例如，对于扬声器2(位于B点)，车辆可以控制扬声器2的播放强度为

图8示出了本申请实施例提供的车辆的中控大屏显示声场优化中心的示意图。车辆在检测到车内的主驾位、副驾位、二排左侧和二排右侧区域有用户时，可以通过中控大屏提示用户“检测到主驾位、副驾位、二排左和二排右有人”，同时提示用户当前的声场优化中心点可以是距离主驾位所在区域的中心点、副驾位所在区域的中心点、二排左所在区域的中心点和二排右所在区域的中心点距离相等的点。
图9示出了本申请实施例提供的当主驾位、副驾位和二排左侧区域有用户时车内扬声器的声场优化中心的示意图。主驾位、副驾位和二排左侧所在区域的中心点可以组成一个三角形EFG，其中三角形EFG的外心可以为Q点。Q点可以为当前车内的声场优化中心点。
示例性的，Q点可以是和O点重合。由于矩形EFGH的中心点Q距离四个扬声器的距离是相等的，那么此时车辆可以控制四个扬声器的播放强度相同(例如，4个扬声器的播放强度均为p)。
示例性的，Q点和O点也可以是不重合的。此时车辆控制4个扬声器的播放强度的方式可以参考上述实施例中的描述，此处不再赘述。
图10示出了本申请实施例提供的车辆的中控大屏显示声场优化中心的示意图。车辆在检测到车内的主驾位、副驾位和二排左侧区域有用户时，可以通过中控大屏提示用户“检测到主驾位、副驾位和二排左有人”，同时提示用户当前的声场优化中心点可以是距离主驾位所在区域的中心点、副驾位所在区域的中心点和二排左所在区域的中心点距离相等的点。

应理解，以上以S501中用户的位置信息为用户所在区域的中心点为例进行说明的，本申请实施例中并不限于此。例如，用户的位置信息还可以是用户所在区域的其他预设点，或者，用户的位置信息还可以是根据预设规则(例如，预设算法)计算得到的区域中的某个点。
一个实施例中，用户的位置信息也可以是根据用户人耳的位置信息确定的。通过摄像装置采集的图像信息可以确定用户人耳的位置信息。例如，用户的人耳位置信息为第一点和第二点连线的中点，其中第一点为用户左耳上的某个点，第二点为用户右耳上的某个点。再例如，用户的人耳的耳廓位置信息等。可以根据用户的人耳的位置信息或者人耳的耳廓的位置信息，确定区域的位置信息。下面结合图27和28介绍当车辆通过用户的位置信息调节了多个发声装置的播放强度后，用户手动调整某个扬声器的播放强度的过程。
图27示出了本申请实施例提供的一组图像用户界面(graphical user interface，GUI)。
如图27中的(a)所示，当主驾位、副驾位、二排左侧区域以及二排右侧区域均有用户时，车辆可以通过HMI提示用户“检测到主驾位、副驾位、二排左和二排右有人”以及提示用户当前声场优化中心。如图27中的(a)所示，主驾位、副驾位、二排左以及二排右上的笑脸表示该区域中有用户。当车辆检测到用户长按二排左侧区域中的笑脸的操作时，可以通过HMI显示图标2701(例如，垃圾箱图标)。当车辆检测到用户将二排左侧区域中的笑脸拖动至图标2701处时，车辆可以通过HMI显示如图27中的(b)所示的GUI。
如图27中的(b)所示，相应于检测到用户将二排左侧区域中的笑脸拖动至图标2701处的操作，车辆可以通过HMI提示用户“已经为您将二排左侧区域的扬声器音量降为0”。
一个实施例中，若主驾位、副驾位、二排左以及二排右上有用户，那么当前4个扬声器的播放强度可以为p。当车辆检测到用户将二排左侧区域中的笑脸拖动至图标2701处的操作时，车辆可以将二排左侧区域的扬声器播放强度降为0，或者，从p降低为0.1p，本申请实施例对此不作限定。
图28示出了本申请实施例提供的一组GUI。
如图28中的(a)所示，当主驾位、副驾位、二排左侧区域以及二排右侧区域均有用户时，车辆可以通过HMI提示用户“检测到主驾位、副驾位、二排左和二排右有人”以及提示用户当前声场优化中心。当车辆在HMI检测到用户的手指在二排左侧区域中向上滑动的操作时，可以显示播放强度的滚动条2801。该播放强度的滚动条2801中可以包括滚动块2802。
如图28中的(b)所示，响应于检测到用户的手指在二排左侧区域中向上滑动的操作， 车辆可以调高二排左侧区域附近的扬声器的播放强度且在HMI上显示滚动块2802向上移动。示例性的，二排左侧区域附近的扬声器的播放强度可以从p提升至1.5p。同时，车辆可以通过HMI提示用户“已经为您将二排左侧区域的扬声器音量提高”。
本申请实施例中，车辆在将第一发声装置的播放强度调节为第一播放强度之后，若检测到用户将某个扬声器的播放强度从第一播放强度调节为第二播放强度的操作，可以将该扬声器的播放强度调节为该第二播放强度。这样可以使得用户快速完成对该区域的扬声器的播放强度进行调节，使得该区域的扬声器更好的满足用户的听音效果。
一个实施例中，车辆还可以通过摄像头采集的图像信息来确定某个区域中用户的状态，从而结合该区域的位置信息以及用户的状态来调节该区域附近的扬声器的播放强度。示例性的，当车辆检测到二排左侧区域有用户且该用户正在休息时，车辆可以控制二排左侧区域附近的扬声器的播放强度为0或者其他数值。
一个实施例中，该第二播放强度也可以为默认播放强度(例如，第二播放强度为0)。当车辆检测到用户在中控大屏上的某个区域(例如二排左侧区域)的预设操作时，车辆可以将该区域的扬声器的播放强度从第一播放强度调节为该默认播放强度。
一个实施例中，该预设操作包括但不限于在该区域中检测到用户的长按操作(例如，长按二排左侧区域中的座位)、在该区域中的滑动或者点击操作等。
应理解，以上结合图6至图28介绍了本申请实施例提供的发声装置的控制方法应用于车内场景时的情况，该控制方法还可以用于其他场景。例如，家庭影院以及KTV的场景中。图29示出了本申请实施例的发声装置的控制方法应用于家庭影院时的示意图。如图29所示，家庭影院中可以包括音箱1、音箱2以及音箱3。家庭影院中的发声***可以通过检测用户与3个音箱之间的位置关系，对3个音箱进行调节。
图30示出了本申请实施例提供的家庭影院下的声场优化中心的示意图。示例性的，以3个音箱所在的点的连线形成的图形是三角形ABC为例，该三角形ABC上的A点设置有音箱1，B点设置有音箱2以及C点设置有音箱3，其中，O点为三角形ABC的外心。
当用户所在区域的中心点和O点重合时，或者，O点位于用户所在区域中时，发声***可以控制音箱1、音箱2和音箱3的播放强度相同(例如，3个音箱的播放强度均为p)。
当用户所在区域的中心点和O点不重合时，或者，O点不位于用户所在区域中时，发声***可以根据用户所在区域与3个音箱之间的位置关系来调节3个音响的播放强度。
例如，以用户所在区域的中心点为Q点为例，对于音箱1(位于A点)，发声***可以控制音箱1的播放强度为

例如，以第一设备为车辆为例。当车辆需要确定主驾区域是否存在用户时，可以获取主驾摄像头采集的图像信息以及主驾位座椅中的压力传感器采集的压力信息。若通过主驾摄像头采集的图像信息确定该图像信息中包括人脸信息且主驾位座椅中的压力传感器采集的压力值大于或者等于第一阈值，那么车辆可以确定主驾区域中存在用户。
又例如，当第一设备需要确定某个区域是否存在用户时，可以获取摄像头采集该区域中的图像信息以及通过麦克风阵列对环境中的声音信息进行拾取。若通过摄像头采集到的该区域的图像信息确定该图像信息中包括人脸信息且通过麦克风阵列采集的声音信息确定声音是来自于该区域，那么车辆可以确定该区域中存在用户。

本申请实施例中，第一设备通过获取多个用户所在的多个区域的位置信息，并根据多个区域的位置信息以及多个发声装置的位置信息，控制多个发声装置工作，无需用户手动调节发声装置，有助于降低用户的学习成本以及减少用户繁琐的操作；同时，也有助于多个用户均可以享受到好的听音效果，有助于提升用户的使用体验。
