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，显然，所描述的实施例仅仅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。
由于传统音响设备的音效相对单一，使得无法满足用户对不同音效的需求，容易引起用户的听觉疲劳。为此，本申请提出了一种基于多个扬声单元的空间分布状态来调整音效的技术方案，克服了音响设备的音效单一的缺陷，增加了音响设备的音效的多样性。
参见图1所示，本申请公开了一种音效调整方法，应用于包含多个扬声单元的音响设备，包括：
步骤S11：确定所述多个扬声单元的空间分布状态。
本实施例中，所述多个扬声单元的空间分布状态既可以包括扬声单元在空间分布时相应的方向信息，还可以进一步包括扬声单元在空间分布时相应的距离值。另外，本实施例具体可以利用麦克风采集到的声音强度，确定所述多个扬声单元的空间分布状态，也可以利用相机采集到的图像信息，确定所述多个扬声单元的空间分布状态，当然还可以利用基于室内定位技术的定位装置采集到的定位信息，确定所述多个扬声单元的空间分布状态。
需要指出的是，所述多个扬声单元既可以是音响设备中的全部扬声单元，也可以是音响设备中全部扬声单元中的若干个扬声单元。可以理解的是，当所述多个扬声单元为所述全部扬声单元中的若干个扬声单元，则在所述步骤S11之前，还需要从所述全部扬声单元中确定出所述多个扬声单元。
在一种具体实施方式中，可以先确定每个扬声单元相对于参照目标的距离值，然后从全部扬声单元中将上述距离值大于预设距离阈值的扬声单元剔除掉，并将剩下的扬声单元确定为所述多个扬声单元。需要说明的是，上述参照目标既可以是小孩、青年人、中年人和老人等聆听对象，也可以是预设装置，其中，上述预设装置既可以是属于音响设备中的一个装置，如音响设备中的控制单元，也可以是由用户通过预设客户端指定的独立于音响设备的一个装置。另外，上述预设距离阈值既可以由用户通过预设客户端进行人工设定，也可以预先由音响设备进行自动设定。具体的，音响设备可以先确定当前自身所处空间环境的空间大小，然后自动确定数值大小与该空间大小呈正相关的所述预设距离阈值。其中，音响设备可以基于光波测距、声波测距、图像深度信息检测等方式来估算出自身所处空间环境的空间大小，也可以通过人工输入信息的方式来获取上述空间大小。
在另一种具体实施方式中，也可以通过人工选取的方式从全部扬声单元中选取出若干个扬声单元，得到所述多个扬声单元。具体的，可以由用户通过上述预设客户端从全部扬声单元中选取出若干个扬声单元来作为所述多个扬声单元。
可以理解的是，本实施例中的所述预设客户端既可以是音响设备中自带的客户端，也可以是手机、平板电脑等手持智能终端上的客户端。
另外，需要指出的是，步骤S11中，所述多个扬声单元的空间分布状态具体可以是各个扬声单元相对于所述参照目标的空间分布状态，也可以是每个扬声单元相对于其他扬声单元的空间分布状态。其中，所述参照目标包括所述聆听对象或所述预设装置。
步骤S12：确定与所述空间分布状态对应的音效模式。
本实施例中，音响设备的音效模式与所述多个扬声单元的空间分布状态之间呈对应关系，可以理解的是，所述多个扬声单元的不同的空间分布状态通常对应于不同的空间分散程度，本实施例，最终确定出来的音效模式的空间感与所述空间分布状态所对应的空间分散程度之间优先呈现正相关关系，也即，空间分散程度越大，音效模式的空间感越强，这样可以使得可以根据用户自身对音效空间感的偏好来调整所述多个扬声单元的空间分布状态，以达到将音响设备的音效模式调整至用户偏好模式的目的。
在一种具体实施方式中，可以通过人工调整方式来调整所述多个扬声单元的空间分布状态，具体的，用户可以通过移动所述扬声单元或所述预设装置的方式来改变所述空间分布状态。
在另一种具体实施方式中，也可以通过控制所述扬声单元或所述预设装置在预设滑轨上滑动的方式来改变所述空间分布状态。具体的，本实施例可以预先设置一个滑动控制规则，其中，所述滑动控制规则包括滑动触发时间以及相应的期望形成的空间分布状态，在当前时间与所述滑动控制规则中预设的滑动触发时间相符时，则自动控制所述扬声单元或所述预设装置在预设滑轨上滑动，以使所述多个扬声单元形成相应的空间分布状态。例如，可以在上述滑动控制规则中记录早上、中午和晚上各自对应的空间分布状态，如果当前时间是早上，则可以从上述滑动控制规则中查找出与早上对应的空间分布状态，然后控制所述扬声单元或所述预设装置做出相应的滑动操作；同理，如果当前时间是晚上，则从上述滑动控制规则中查找出与晚上对应的空间分布状态，然后控制所述扬声单元或所述预设装置做出相应的滑动操作。由此，可以满足用户在不同时间下对音效的不同需求，提升了用户体验。本实施例中，上述滑动控制规则可以由用户进行自主设置。
步骤S13：根据所述音效模式对所述音响设备的音效进行调整。
具体的，本实施例通过上述步骤S12确定出相应的音效模式之后，可以根据该音效模式确定出所述多个扬声单元中每个扬声单元的相应的工作参数，然后根据上述工作参数控制扬声单元进入相应的工作状态，以形成所述音效模式。
在一种具体实施方式中，所述根据所述音效模式对所述音响设备的音效进行调整，具体可以包括：直接根据所述音效模式对所述音响设备的音效进行自动调整。也即，本实施例通过上述步骤S12确定出音效模式之后，可以直接地自动根据该音效模式对音响设备的音效进行调整，这个过程是一种全程自动化处理的过程，无需用户介入，提高了音效调整方案的智能化和自动化程度
在另一种具体实施方式中，所述根据所述音效模式对所述音响设备的音效进行调整，具体可以包括：监测是否获取到预设客户端发送的调整指令，如果是，则根据所述音效模式对所述音响设备的音效进行调整。也即，本实施例通过上述步骤S12确定出音效模式之后，还需要进一步监测是否获取到预设客户端发送的调整指令，如果监测到该指令，则可以根据所述音效模式对音效进行调整，如果没有监测到该指令，则不对音效进行调整。也即，本实施例在确定出音效模式之后，并不会直接展开音效调整处理，而是需要用户通过预设客户端触发调整指令并发送至音响设备，当音响设备获取到该调整指令之后，才会根据所述音效模式进行音效调整处理，这个过程需要用户的介入，提高了用户参与程度，有利于改善用户体验。
可见，本申请实施例的音效调整方案应用于包含多个扬声单元的音响设备中，先确定出上述多个扬声单元的空间分布状态，接着确定与上述空间分布状态对应的音效模式，然后根据该音效模式对音响设备进行相应地调整。也即，本申请实施例可以根据音响设备内多个扬声单元的空间分布状态对音效模式进行相应的调整，这样，当上述空间分布状态发生变化之后，音响设备的音效模式也可以随之发生改变，由此克服了音响设备的音效单一的缺陷。综上，本申请实施例能够有效增加音响设备的音效的多样性。
参见图2所示，本申请实施例公开了一种具体的音效调整方法，应用于包含多个扬声单元的音响设备，包括：
步骤S21：确定每个扬声单元相对于预设装置的方向。
在第一种具体实施方式中，可以利用安装于所述预设装置的多个麦克风，确定出每个扬声单元对应的多个声音强度，然后根据每个扬声单元对应的多个声音强度，相应地确定出每个扬声单元相对于所述预设装置的方向。也即， 本实施例可以预先在所述预设装置上安装多个麦克风。在确定每个扬声单元相对于所述预设装置的方向时，控制不同的扬声单元在不同的时刻下播放预设音频，并在扬声单元播放预设音频时通过上述多个麦克风采集每个扬声单元对应的多个声音强度，可以理解的是，本实施例中不同麦克风具有不同的安装位置，也即，不同麦克风相对于同一个扬声单元的方位是不尽相同的，存在着差异，从而使得通过所述多个麦克风采集到的与每个扬声单元对应的多个声音强度也存在着差异，通过分析每个扬声单元对应的多个声音强度之间的差异，可以确定出每个扬声单元相对于所述多个麦克风所在位置的方向，也即确定出每个扬声单元相对于所述预设装置的方向。可以理解的是，所述多个麦克风中的麦克风数量越多，在空间分布越均匀，其最终确定出来的方向越精确。
参见图3所示，图3示出了一种具体的音响设备应用场景，其中，音响设备包括放置在电视柜上的扬声单元A1、扬声单元A2、扬声单元A3和放置在茶几上的控制单元A0，控制单元A0中预先安装了麦克风环形阵列，如图4所示，该麦克风环形阵列中包括均匀排布的8个麦克风。在确定每个扬声单元相对于控制单元A0的方向时，控制单元A0可以依次控制扬声单元A1、A2和A3分别播放同一个预设音频，例如均按照相同的发声频率和音量参数发出“嘀”声，然后利用上述8个麦克风分别采集与每个扬声单元对应的8个声音强度，接着基于每个扬声单元对应的8个声音强度之间的差异来确定出每个扬声单元相对于控制单元A0的方向。
在第二种具体实施方式中，可以利用安装于所述预设装置的第一相机，对所述多个扬声单元所处的空间环境进行图像采集，得到第一全景图像，并识别所述第一全景图像中每个扬声单元对应的图像区域，得到多个图像区域，接着根据所述多个图像区域，确定出每个扬声单元相对于所述预设装置的方向。
在第三种具体实施方式中，可以利用每个扬声单元内置的基于室内定位技术的定位装置，对每个扬声单元进行空间定位，得到每个扬声单元的定位信息，并利用预设装置中内置的基于室内定位技术的定位装置，对所述预设装置进行空间定位，得到所述预设装置的定位信息，然后利用所述预设装置的定位信息和每个扬声单元的定位信息，确定出每个扬声单元相对于所述预设装置的方向。本实施例中，所述室内定位技术包括但不限于WiFi室内定位技术、蓝牙室内定位技术、超宽带室内定位技术和ZigBee室内定位技术。
可以理解的是，上述公开的仅仅是本实施例中的三个具体实施方案，并非是对本实施例的限制，除了上述三个具体实施方案之外，也可以采用其他 可行方案来实现确定每个扬声单元相对于预设装置的方向的目的，在此不便一一列举。
步骤S22：确定与所述空间分布状态对应的音效模式。
从图3中可以看出，扬声单元A1、扬声单元A2和扬声单元A3处于组合状态，紧靠在一起，这种情况下扬声单元A1、扬声单元A2和扬声单元A3所形成的空间分散程度相对较低，相应地，与上述空间分散程度对应的音效模式的空间感也相对较弱，只需保证具有一定的立体声效果即可。另外，除了采用如图3所示的扬声单元摆放方式来形成所述多个扬声单元的空间分布状态，本实施例也可以采用如图5、图6或图7所示的方式。其中，图5中的扬声单元A1、扬声单元A2和扬声单元A3依然被放置在电视柜上，但已处于分离状态，而非组合状态，这种情况相对于图3中的情况具有更高的空间分散程度，与此对应的音效模式的空间感也更强些；图6中的扬声单元A2依然被放置在电视柜上，但扬声单元A2和扬声单元A3则分别被放置在沙发两侧的小柜子上，这种情况相对于图5中的情况具有更高的空间分散程度，与此对应的音效模式的空间感也更强，例如，与当前情况对应的音效模式可以设为杜比音效，以形成空间感更强的环绕立体声，满足大客厅的空间需求；图7中的扬声单元A1与控制单元A0处于组合状态，此时可以直接将上述三个扬声单元的空间分布状态确定为预设特殊分布状态，与该预设特征分布状态对应的音效模式的空间感具体可以为极小值，理论上该极小值为零，后续基于该音效模式对音响设备进行音效调整时，只需控制扬声单元A1播放音频即可，而禁止扬声单元A2和A3播放音频，这样可以使得最终输出的音效的空间感为所述极小值。也即，本实施例中，一旦监测到控制单元与任一扬声单元处于组合状态，则可以将所述多个扬声单元的空间分布状态确定为所述预设特殊分布状态，并根据所述预设特殊分布状态确定出空间感为所述极小值的音效模式，通过该音效模式可以只允许与所述控制单元组合在一起的扬声单元播放音频，而禁止其他扬声单元发声。其中，本实施例可以通过磁吸或卡接等固定方式，将任一扬声单元与控制单元组合到一起，以形成一个带有控制单元的独立智能音箱，这样用户可以在外出的时候随身带上所述独立智能音箱，或者可以将所述独立智能音箱从客厅移到卧室使用。
