蓝牙自适应音量调节方法及装置 技术领域
本发明涉及电视技术领域，尤其涉及一种蓝牙自适应音量调节方法及装置。
背景技术
目前，蓝牙功能已成为人们日常生活中经常使用的功能，广泛应用于智能手机、智能电视等终端设备。其中蓝牙音箱、耳机更是人们常用的蓝牙音频设备，人们对其音频设备要求最多的就是音质和音量。当智能电视带有蓝牙功能，其音量调整方法就变得更加复杂，因为电视端自身具有音量调节功能(只针对蓝牙通道)，而蓝牙音频设备也有自身音量调节开关。
目前带蓝牙功能的智能电视，当成功连接上蓝牙音频设备后，调整蓝牙音量的做法为：用户调整电视端蓝牙通道音量(通过遥控或按键板音量加/减)，此时所调整的是：电视IC控制音量的增益值大小，此大小会对电视送出声音大小做调节。如果此时蓝牙音频设备端音量很小，调试电视端音量大小变化会有一定限制，变化范围很小，这时用户又需要手动调整蓝牙音频设备音量,这样造成用户体验很差。
另外，上述音量调试方法还有一种缺陷是：当蓝牙音频设备音量调到最大值(max)时，电视连接此蓝牙音频设备后，通过音量键调节电视端音量增益时，容易失真。

为了使本发明的技术方案更加清楚、明了，下面将结合附图作进一步详述。
具体实施方式
如图1所示，本发明第一实施例提出一种蓝牙自适应音量调节方法，包括：
步骤S101，智能终端与蓝牙音频设备连接后，获取所述蓝牙音频设备的可调最大音量值和用户可调最大音量值；
本实施例方案适用于使用标准蓝牙协议的音频播放设备之间，其中，智能终端可以为智能电视(TV)、mp3、手机等具有音视频播放功能的终端，本实施例以智能电视进行举例。
标准的蓝牙A2dp协议，蓝牙音频设备端就是SNK(音频信宿设备)，TV端就是source(音频信源设备)。
由于现有的带蓝牙功能的智能电视，当成功连接上蓝牙音频设备后，调整蓝牙音量的方案中，若蓝牙音频设备端音量很小，调试电视端音量大小变化会有一定限制，变化范围很小，用户需要手动调整蓝牙音频设备音量，这样造成用户体验很差。另外，当蓝牙音频设备音量调到最大值(max)时，电视连接此蓝牙音频设备后，通过音量键调节电视端音量增益时，容易失真。
本实施例提出一种解决方案，能够同时均匀调节智能终端(比如电视端)以及蓝牙端音量，以达到平滑匀速调节音量的效果，解决现有技术调节蓝牙音量中的失真、音量调整变化小等问题。
具体地，在智能终端与蓝牙音频设备连接后，记录此蓝牙音频设备的ID，通过蓝牙协议，获取所述蓝牙音频设备的可调最大音量值BVolmax,同时获取智能终端屏幕显示的设置菜单上用户可调最大音量值，即用户按键设置的可调最大音量值，并将上述两个音量值记录下来。
步骤S102，在接收到音量调节指令后，获取所述音量调节指令指示的音量值；
用户可以通过遥控器或者智能终端本地的按键面板进行音量调节，触发音量调节指令，智能终端在接收到音量调节指令后，获取所述音量调节指令指示的音量值，即智能终端显示的音量值Volc。
步骤S103，根据所述音量调节指令指示的音量值，计算得到所述智能终端的音量值，根据所述音量调节指令指示的音量值、所述蓝牙音频设备的可调最大音量值及用户可调最大音量值，计算得到所述蓝牙音频设备的音量值；
之后，可以根据设定的映射公式，根据所述音量调节指令指示的音量值，计算得到所述智能终端的音量值，根据所述音量调节指令指示的音量值、所述蓝牙音频设备的可调最大音量值及用户可调最大音量值，计算得到所述蓝牙音频设备的音量值。
其中，设定的映射公式可以如下：
当调整音量时，菜单音量值按如下公式1计算出映射电视底层蓝牙音量增益值VolGc，即智能终端的音量值。
公式1：
VolGc＝k*Volc；
其中，Volc：菜单上显示当前设置音量值，即音量调节指令指示的音量值；
Volmax：可以取值100(菜单上用户可调最大音量值)；
VolGc：映射底层需设置电视音量当前增益值，即智能终端的音量值；
k:系数(斜率)，其大小取决于电视DSP支持设置的最大音量增益值，若默认100，则k＝1。
根据上述公式1可得到映射关系如图2所示。
在图2中，VolGain是指智能终端的音量增益值，VolGmax是指电视DSP支持设置的最大音量增益值；Vol(OSD)是指电视屏幕菜单上显示的设置音量值。
根据图2体现的电视音量当前增益值与菜单上显示当前设置音量值之间的映射关系，当调整音量时，计算出映射电视底层蓝牙音量增益值VolGc，即智能终端的音量值。
另外，当调整音量时，读取到蓝牙音频设备可设置的最大音量值BVolmax。并按如下公式2计算出发送给蓝牙音频设备需设置的蓝牙音频设备的音量值B`Volc。
公式2：
Figure PCTCN2016084836-appb-000004
其中，Volc：菜单上显示当前设置音量值，即音量调节指令指示的音量值；
Volmax：可以取值100(菜单上用户可调最大音量值)；
BVolmax:蓝牙音频设备可调最大音量。
根据公式2得如图3所示的映射关系。
根据图3体现的映射关系进行音量调节，可以较快速增大电视音量，并且是平滑调节。
步骤S104，根据得到的所述蓝牙音频设备的音量值设置所述蓝牙音频设备的音量，根据得到的所述智能终端的音量值设置所述智能终端的音量。
之后，根据接收到的音量按键触发信息，分别设置上述计算出的对应的菜单电视增益值VolGc，及蓝牙音频设备端音量B`Volc。
在具体设置时，可以采用如下方案：
按音量增时，调用TV_Set_Volume_Gain(VolGc)和Send_BT_Volume(ID,B`Volc,VolumeUp)，(其中，ID：连接上蓝牙音频设备ID，代码中实现接口，就是通过蓝牙协议将第三参数(前述括号中第三个参数VolumeUp)发送到SNK端，此参数是预留调整绝对音量用的，即第二参数(前述括号中第二个参数B`Volc)如果为空，就可以根据第三参数来增大或减少音量)；
按音量减时，调用TV_Set_Volume_Gain(VolGc)和Send_BT_Volume(ID,B`Volc,VolumeDown)，分别设置电视端增益值，以及蓝牙音频设备音量值。
后续，当再次接收到用户的音量调节指令时，返回执行步骤：获取所述音量调节指令指示的音量值，并按照上述计算方法调节电视端和蓝牙音频设备端音量。
本实施例通过上述方案，智能终端在与蓝牙音频设备连接后，获取蓝牙音频设备的可调最大音量值和用户可调最大音量值；在接收到音量调节指令后，获取所述音量调节指令指示的音量值；根据音量调节指令指示的音量值，计算得到所述智能终端的音量值，根据音量调节指令指示的音量值、蓝牙音频设备的可调最大音量值及用户可调最大音量值，计算得到蓝牙音频设备的音量值；根据得到的蓝牙音频设备的音量值设置蓝牙音频设备的音量，根据得到的智能终端的音量值设置智能终端的音量，由此，通过上述方案，自适应两端蓝牙音量调节，用户可以通过遥控音量键或电视端调节音量按键同时均匀调整电视端音量增益值以及蓝牙音频设备端音量，以达到平滑匀速调整音量效果，解决现有调整蓝牙音量中的失真、音量调整变化小等问题，提高用户体验，从而提高用户产品竞争性。
此外，为避免设置蓝牙音频声音过大时，再调整电视端音量增益而导致音量失真，如图4所示，本发明第二实施例提出一种蓝牙自适应音量调节方法，基于上述图1所述的实施例，在上述步骤S104：根据得到的所述蓝牙音频设备的音量值设置所述蓝牙音频设备的音量，根据得到的所述智能终端的音量值设置所述智能终端的音量之前还包括：
步骤S105，判断所述音量调节指令指示的音量值是否大于用户可调最大音量值的预定比例阈值；若是，则进入步骤S106，否则，执行步骤S104。
步骤S106，将所述智能终端的音量值设置为一与所述用户可调最大音量值相关的定值，并可以根据得到的所述蓝牙音频设备的音量值设置所述蓝牙音频设备的音量。
相比上述实施例，本实施例在设置智能终端的音量值时，会考虑用户按键设置的音量值是否过大，可以设定一预定比例阈值，判断用户按键设置的音量值是否大于用户可调最大音量值的预定比例阈值，比如音量值是否大于用户可调最大音量值的一半，若是，则将所述智能终端的音量值设置为一与所述用户可调最大音量值相关的定值，即：判断菜单上Volc是否大于
Figure PCTCN2016084836-appb-000005
如果大于，则将电视端增益值设置为定值，即
Figure PCTCN2016084836-appb-000006
这样为避免设置蓝牙音频声音过大时，再调整电视端音量增益而导致音量失真。
其中，k:系数(斜率)其大小取决于电视DSP支持设置的最大音量增益值，若默认100，则k＝1。
此外，同样可以根据得到的所述蓝牙音频设备的音量值设置所述蓝牙音频设备的音量。
以下结合图5对本发明实施例方案进行详细阐述：
步骤1：打开电视蓝牙功能，加载蓝牙驱动，扫描蓝牙音频设备，从扫描到蓝牙音频设备中选择蓝牙音频设备，建立连接，连接成功后，记录此设备 ID以及连接状态connect_status(1：成功连接；0：未连接)。
步骤2：电视成功连接上蓝牙音频设备后，通过蓝牙协议，读取到当前所连接的蓝牙音频设备可设置的最大音量BVolmax,并记录下来。读取菜单上显示音量值Volc。
步骤3：当用户操作音量按键时，根据上述公式1、2将菜单上音量值大小映射电视音量增益值VolGc及蓝牙音频设备音量值B`Volc。分别同时调整电视DSP蓝牙音量通道的音量增益值(Gain)，及蓝牙音频设备端音量值。
步骤4：判断菜单上Volc是否大于
Figure PCTCN2016084836-appb-000007
如果大于，电视端增益值就设置为定值，即
Figure PCTCN2016084836-appb-000008
这样为避免设置蓝牙音频声音过大时，再调整电视端音量增益而导致音量失真。
步骤5：根据收到音量按键触发信息分别设置上述步骤中计算出的对应的菜单电视增益值VolGc，及蓝牙音频设备端音量B`Volc。即按音量增时调用TV_Set_Volume_Gain(VolGc)和Send_BT_Volume(ID,B`Volc,VolumeUp)；按音量减时调用TV_Set_Volume_Gain(VolGc)和Send_BT_Volume(ID,B`Volc,VolumeDown)，分别设置电视端增益值，以及蓝牙音频设备音量值。
本实施例通过上述方案，智能终端在与蓝牙音频设备连接后，获取蓝牙音频设备的可调最大音量值和用户可调最大音量值；在接收到音量调节指令后，获取所述音量调节指令指示的音量值；根据音量调节指令指示的音量值，计算得到所述智能终端的音量值，根据音量调节指令指示的音量值、蓝牙音频设备的可调最大音量值及用户可调最大音量值，计算得到蓝牙音频设备的音量值；根据得到的蓝牙音频设备的音量值设置蓝牙音频设备的音量，根据得到的智能终端的音量值设置智能终端的音量，由此，通过上述方案，自适应两端蓝牙音量调节，用户可以通过遥控音量键或电视端调节音量按键同时均匀调整电视端音量增益值以及蓝牙音频设备端音量，以达到平滑匀速调整音量效果，解决现有调整蓝牙音量中的失真、音量调整变化小等问题，提高用户体验，从而提高用户产品竞争性。而且本发明可以减少电视生产过程中的设备人员的投入，实现自动化生产。
对应地，提出本发明蓝牙自适应音量调节装置实施例。
如图6所示，本发明第一实施例提出一种蓝牙自适应音量调节装置，包括：第一获取模块201、第二获取模块202、计算模块203及设置模块204，其中：
第一获取模块201，用于在智能终端与蓝牙音频设备连接后，获取所述蓝牙音频设备的可调最大音量值和用户可调最大音量值；

本实施例方案适用于是使用标准蓝牙协议的音频播放设备之间，其中，智能终端可以为智能电视(TV)、mp3、手机等具有音视频播放功能的终端，本实施例以智能电视进行举例。
标准的蓝牙A2dp协议，蓝牙音频设备端就是SNK(音频信宿设备)，TV端就是source(音频信源设备)。
由于现有的带蓝牙功能的智能电视，当成功连接上蓝牙音频设备后，调整蓝牙音量的方案中，若蓝牙音频设备端音量很小，调试电视端音量大小变化会有一定限制，变化范围很小，用户需要手动调整蓝牙音频设备音量，这样造成用户体验很差。另外，当蓝牙音频设备音量调到最大值(max)时，电视连接此蓝牙音频设备后，通过音量键调节电视端音量增益时，容易失真。
本实施例提出一种解决方案，能够同时均匀调节智能终端(比如电视端)以及蓝牙端音量，以达到平滑匀速调节音量的效果，解决现有技术调节蓝牙音量中的失真、音量调整变化小等问题。
具体地，在智能终端与蓝牙音频设备连接后，记录此蓝牙音频设备的ID， 通过蓝牙协议，获取所述蓝牙音频设备的可调最大音量值BVolmax,同时获取智能终端屏幕显示的设置菜单上用户可调最大音量值，即用户按键设置的可调最大音量值，并将上述两个音量值记录下来。
用户可以通过遥控器或者智能终端本地的按键面板进行音量调节，触发音量调节指令，智能终端在接收到音量调节指令后，获取所述音量调节指令指示的音量值，即智能终端显示的音量值Volc。
之后，可以根据设定的映射公式，根据所述音量调节指令指示的音量值，计算得到所述智能终端的音量值，根据所述音量调节指令指示的音量值、所述蓝牙音频设备的可调最大音量值及用户可调最大音量值，计算得到所述蓝牙音频设备的音量值。
其中，设定的映射公式可以如下：
当调整音量时，菜单音量值按如下公式1计算出映射电视底层蓝牙音量增益值VolGc，即智能终端的音量值。
公式1：
VolGc＝k*Volc；
其中，Volc：菜单上显示当前设置音量值，即音量调节指令指示的音量值；
Volmax：可以取值100(菜单上用户可调最大音量值)；
VolGc：映射底层需设置电视音量当前增益值，即智能终端的音量值；

根据上述公式1可得到映射关系如图2所示。
在图2中，VolGain是指智能终端的音量增益值，VolGmax是指电视DSP支持设置的最大音量增益值；Vol(OSD)是指电视屏幕菜单上显示的设置音量值。
根据图2体现的电视音量当前增益值与菜单上显示当前设置音量值之间的映射关系，当调整音量时，计算出映射电视底层蓝牙音量增益值VolGc，即智能终端的音量值。
另外，当调整音量时，读取到蓝牙音频设备可设置的最大音量值BVolmax。并按如下公式2计算出发送给蓝牙音频设备需设置的蓝牙音频设备的音量值B`Volc。
公式2：

之后，根据接收到的音量按键触发信息，分别设置上述计算出的对应的菜单电视增益值VolGc，及蓝牙音频设备端音量B`Volc。
在具体设置时，可以采用如下方案：
按音量增时，调用TV_Set_Volume_Gain(VolGc)和Send_BT_Volume(ID,B`Volc,VolumeUp)，(其中，ID：连接上蓝牙音频设备ID，代码中实现接口，就是通过蓝牙协议将第三参数(前述括号中第三个参数VolumeUp)发送到SNK端，此参数是预留调整绝对音量用的，即第二参数(前述括号中第二个参数B`Volc)如果为空，就可以根据第三参数来增大或减少音量)；
按音量减时，调用TV_Set_Volume_Gain(VolGc)和Send_BT_Volume(ID,B`Volc,VolumeDown)，分别设置电视端增益值，以及蓝牙音频设备音量值。
后续，当再次接收到用户的音量调节指令时，返回执行步骤：获取所述音量调节指令指示的音量值，并按照上述计算方法调节电视端和蓝牙音频设备端音量。
本实施例通过上述方案，智能终端在与蓝牙音频设备连接后，获取蓝牙音频设备的可调最大音量值和用户可调最大音量值；在接收到音量调节指令后，获取所述音量调节指令指示的音量值；根据音量调节指令指示的音量值，计算得到所述智能终端的音量值，根据音量调节指令指示的音量值、蓝牙音频设备的可调最大音量值及用户可调最大音量值，计算得到蓝牙音频设备的音量值；根据得到的蓝牙音频设备的音量值设置蓝牙音频设备的音量，根据得到的智能终端的音量值设置智能终端的音量，由此，通过上述方案，自适 应两端蓝牙音量调节，用户可以通过遥控音量键或电视端调节音量按键同时均匀调整电视端音量增益值以及蓝牙音频设备端音量，以达到平滑匀速调整音量效果，解决现有调整蓝牙音量中的失真、音量调整变化小等问题，提高用户体验，从而提高用户产品竞争性。
如图7所示，本发明第二实施例提出一种蓝牙自适应音量调节装置，基于上述图6所示的实施例，该装置还包括：
判断模块205，用于判断所述音量调节指令指示的音量值是否大于用户可调最大音量值的预定比例阈值；若是，则由所述设置模块204将所述智能终端的音量值设置为一与所述用户可调最大音量值相关的定值；否则由所述设置模块204根据得到的所述蓝牙音频设备的音量值设置所述蓝牙音频设备的音量，根据得到的所述智能终端的音量值设置所述智能终端的音量。
相比上述实施例，本实施例在设置智能终端的音量值时，会考虑用户按键设置的音量值是否过大，可以设定一预定比例阈值，判断用户按键设置的音量值是否大于用户可调最大音量值的预定比例阈值，比如音量值是否大于用户可调最大音量值的一半，若是，则将所述智能终端的音量值设置为一与所述用户可调最大音量值相关的定值，即：判断菜单上Volc是否大于
Figure PCTCN2016084836-appb-000010
如果大于，则将电视端增益值设置为定值，即
Figure PCTCN2016084836-appb-000011
这样为避免设置蓝牙音频声音过大时，再调整电视端音量增益而导致音量失真。
其中，k:系数(斜率)其大小取决于电视DSP支持设置的最大音量增益值，若默认100，则k＝1。
此外，同样可以根据得到的所述蓝牙音频设备的音量值设置所述蓝牙音频设备的音量。
本实施例通过上述方案，智能终端在与蓝牙音频设备连接后，获取蓝牙 音频设备的可调最大音量值和用户可调最大音量值；在接收到音量调节指令后，获取所述音量调节指令指示的音量值；根据音量调节指令指示的音量值，计算得到所述智能终端的音量值，根据音量调节指令指示的音量值、蓝牙音频设备的可调最大音量值及用户可调最大音量值，计算得到蓝牙音频设备的音量值；根据得到的蓝牙音频设备的音量值设置蓝牙音频设备的音量，根据得到的智能终端的音量值设置智能终端的音量，由此，通过上述方案，自适应两端蓝牙音量调节，用户可以通过遥控音量键或电视端调节音量按键同时均匀调整电视端音量增益值以及蓝牙音频设备端音量，以达到平滑匀速调整音量效果，解决现有调整蓝牙音量中的失真、音量调整变化小等问题，提高用户体验，从而提高用户产品竞争性。而且本发明可以减少电视生产过程中的设备人员的投入，实现自动化生产。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本发明的专利保护范围内。
