本发明的一个方面提供了一种数据传输方法，应用于音频设备与智能终端之间的数据传输。
图1为本发明实施例提供的应用于音频设备与智能终端之间的数据传输方法流程图，如图1所示，本实施例的数据传输方法包括：
S110，音频设备接收智能终端发送的第一音频信号，获取该第一音频信号的特征参数。

本实施例的音频设备在接收到智能终端发送的第一音频信号时，根据第一音频信号的特征参数获得解码规则，对智能终端发送的第二音频信号进行解码，获得智能终端发送的数据信息，通过音频信号实现音频设备与智能终端之间的数据传输。
本实施例的数据传输方法不同于现有的wifi、蓝牙等无线传输方式，音频设备和智能终端只需预先约好定通信协议，对音频信号进行处理即可实现数据传输，而无需内置wifi、蓝牙等无线传输模块，且该预先约定好的通信协议相比于wifi、蓝牙等采用固定通信协议的方式，不易被他人发现或截取，安全性较高。总之，本实施例的数据传输方式操作简便、新颖、趣味性强，安全性高，丰富了数据传输方式，提供了不同的使用体验。
在本发明的一些实施例中，第一音频信号包括多次音频信号，每次音频信号均为声波信号，声波信号包括频率、振幅等基本特征参数，其中，多次音频信号即多次声波信号，本实施例是通过下述方法确定第二音频信号的解码规则：
确定第一音频信号的第一次音频信号的特征参数为标准特征参数，该特征参数包括第一次音频信号的频率、振幅等；即以接收的第一次声波信号的频率、振幅等作为标准特征参数；
当第一音频信号的连续至少两次的音频信号的特征参数与标准特征参数一致时，可以确定第一音频信号的发送端，即智能终端为与音频设备匹配的合法设备，此时将继续接收智能终端发送的第二音频信号。第一音频信号还包括连续至少两次的音频信号，即智能终端发送的声波信号至少是三次，后续每次声波信号的特征参数(包括频率和振幅)均与第一次声波信号的标准特征参数作对比，通过两次对比，从而确认是否继续接收智能终端发送的第二音频信号。
当第二音频信号的特征参数与标准特征参数一致时，可以排除外界噪音的干扰，确 定接收到的第二音频信号为有效信号，此时可以根据标准特征参数获取第二音频信号的解码规则。
需要说明的是，本实施例通过预设通讯协议约定第一音频信号包括的多次音频信号的次数。下面以预设通讯协议约定第一音频信号包括三次音频信号为例说明确定第二音频信号的解码规则的过程。
图2为本发明实施例提供的第一音频信号转换为电信号后电信号示意图。根据本发明的实施例，第一音频信号为声波信号，声波信号包括频率、振幅等基本特征参数，声波信号可以转换为电信号，其中当有声波信号出现时，对应该电信号为高电平，当声波信号不出现，对应该电信号为低电平。假设，第一音频信号包括三次音频信号，相应的，即音频设备接收到三次声波信号，三次声波信号转换的电信号如图2所示。
以图2所示的第一音频信号为例，第一音频信号包括三次音频信号，将第一次音频信号的频率、振幅等特征参数作为标准特征参数，当第二次音频信号和第三次音频信号的特征参数均与该标准特征参数一致时，进一步检测各次音频信号转换的电信号之间的时长关系，在各次音频信号转换的电信号之间的时长满足预设时长关系时，根据本发明的实施例，在各次音频信号转换的电信号之间的时长一致时，如图2所示，第一次音频信号的电信号的高电平持续时长与第二次、第三次音频信号的电信号的高电平持续时长一致时，接收智能终端发送的第二音频信号，并根据标准特征参数获取第二音频信号的解码规则。当第二次音频信号和第三次音频信号的特征参数与该标准特征参数不一致时，或者，各次音频信号转换的电信号之间的时长不满足预设时长关系时，不接收或删除接收到的第二音频信号。
需要说明的是，为避免外界噪音对第二音频信号的干扰，在接收到的第二音频信号的特征参数(包括频率和振幅)与标准特征参数一致时，确定接收到的第二音频信号为有效信号，此时再根据标准特征参数获取第二音频信号的解码规则。
本实施例中的解码规则包括按照预设的解码常量与二进制编码之间的对应关系对第二音频信号中编码的数据信息进行解码的规则。由于电平高低与二进制编码1或0相对应，例如，高电平对应二进制编码1，低电平对应二进制编码0。相应的，本实施例在确定解码规则时，是根据第一音频信号的特征参数和预设通讯协议确定第二音频信号的解码常量；其中，预设通讯协议包括预设音频信号的特征参数与解码常量之间的协议 关系。根据本发明的实施例，预设通讯协议用于根据预设特征参数与解码常量之间的协议关系，以及所获取的第一音频信号的标准特征参数，来得到解码常量。
本实施例通过下述方法对第二音频信号进行解码：
根据本发明的实施例，将接收到的第二音频信号转换为高低电平信号，该高低电平信号对应为二进制编码；由于第二音频信号为声音信号，其中当有声波信号出现时，对应该电信号为高电平，当声波信号不出现，对应该电信号为低电平。可选地，亦可以根据分贝高低将第二音频信号转换为高低电平信号，如设置以分贝阈值，将第二音频信号中高于该分贝阈值的部分转换为高电平信号，将第二音频信号中低于该分贝阈值的部分转换为低电平信号。
根据预设音频信号的特征参数与解码常量之间的协议关系，获取第一音频信号的特征参数对应的解码常量；根据解码常量与二进制编码之间的对应关系，对第二音频信号中编码的数据信息进行解码，得到第二音频信号中编码的数据信息。其中，根据本发明的实施例，解码常量可以理解为：一位二进制编码1或0占用的声波时长；例如，假设第二音频信号转换的电平信号为101，其中第一个高电平信号的时长为30毫秒，低电平信号的时长为20毫秒，第二个高电平信号的时长为10毫秒，若解码常量为10毫秒，可知该第一个高电平信号包括3个解码高电平，低电平信号包括2个解码低电平，第二个高电平信号包括1个解码高电平，则该待传输数据信息对应的二进制编码为111001。
在本发明的一些实施例中，为保证数据传输的安全性和可靠性，在进行数据传输时，音频设备获取智能终端相对音频设备的第一距离，获取距离的手段本发明不做限定。可以采用音频测距离的现有手段，例如：智能终端在音频信号中加入发送时刻的时间戳，音频设备接收到智能终端发送的该音频信号后，解析出该发送时刻的时间戳，然后根据接收时刻的时间戳和声音信号的传输速率，获知智能终端相对音频设备的距离。
接着，音频设备根据第一距离以及预设距离的关系，确定是否获取智能终端发送的第一音频信号，如当第一距离小于预设距离时，获取智能终端发送的第一音频信号，当第一距离大于预设距离时，不获取智能终端发送的第一音频信号。
本实施例所传输的数据信息可以包括数据文件信息、文本信息、指令信息等。在实际应用中，可以根据应用场景设置所传输的数据信息。例如，在智能终端控制音频设备联网时，数据信息包括智能终端发出的音频设备开启无线网络功能的控制指令，以及对 应无线网络的账户名称和账户密码，其中账户名称和账户密码可以是文本信息。音频设备在对第二音频信号进行解码后，可以获取控制指令、无线网络的账户名称与账户密码。此时，音频设备根据接收的音频设备开启无线网络功能的控制指令，控制开启无线网络功能，将无线网络的账户名称和账户密码与预设账户名称和预设账户密码进行匹配，以使得音频设备连接无线网络。
本发明的另一个方面提供了一种数据传输方法，应用于音频设备与智能终端之间的数据传输。
图3为本发明实施例提供的应用智能终端与音频设备之间的数据传输方法流程图，如图3所示，本实施例的数据传输方法包括：
S310，智能终端生成第一音频信号，向音频设备发送该第一音频信号。
本实施例的智能终端需处于音频设备的有效接收范围内，以使音频设备可以接收到智能终端发送的音频信号。本实施例的智能终端包括但不限于智能手机、PAD。
本实施例的智能终端所发送的第一音频信号具有特定的频率、振幅等特征参数，以使音频设备根据第一音频信号获取对智能终端发送的第二音频信号进行解密的解码规则。
S320，根据第一音频信号的特征参数获取第二音频信号的编码规则。
本实施例特征参数包括但不限于第一音频信号的频率、振幅等参数。
S330，根据编码规则将待传输的数据信息编码到第二音频信号中，以生成第二音频信号，并将编码后的第二音频信号发送给音频设备。
本实施例的智能终端向音频设备发送具有特定特征参数的第一音频信号，并利用特征参数对第二音频信号进行编码，将编码后的第二音频信号发送给音频设备，以使音频设备根据第一音频信号的特征参数获得解码规则，对智能终端发送的第二音频信号进行解码，获得智能终端发送的数据信息。
本实施例通过音频信号实现音频设备与智能终端之间的数据传输，数据传输方法不同于现有的wifi、蓝牙等无线传输方式，音频设备和智能终端只需预先约定好通信协议对音频信号进行处理，即可实现数据传输，而无需内置wifi、蓝牙等无线传输模块，且该预先约定好的通信协议相比于wifi、蓝牙等采用固定通信协议的方式，不易被他人发现或截取，安全性较高。总之，本实施例的数据传输方式操作简便、新颖、趣味性强， 安全性高，丰富了数据传输方式，提供了不同的使用体验。
在本发明的一些实施例中，第一音频信号包括多次音频信号，其中，第一次音频信号的特征参数为标准特征参数，第一音频信号还包括音频信号的特征参数与标准特征参数一致的至少两次的连续音频信号。
需要说明的是，本实施例通过预设通讯协议约定第一音频信号包括的多次音频信号的次数。下面以预设通讯协议约定第一音频信号包括三次音频信号为例说明智能终端向音频设备发送第一音频信号的过程。
智能终端生成第一音频信号的第一次音频信号，按照第一次音频信号的振幅、频率等参数生成第二次音频信号和第三次音频信号；将生成的第一音频信号发送给音频设备。如图2所示，智能终端将生成的第一音频信号转换为电信号后，该电信号包括三组高低电平信号，每组高低电平信号中的高电平持续时长表示每次声音信号的声波时长。
本实施例中的编码规则包括按照预设的音频信号的编码常量与二进制编码之间的对应关系对待传输数据信息进行编码的规则。相应的，本实施例在确定编码规则时，是根据特征参数和预设通讯协议获取编码常量；其中，预设通讯协议包括预设音频信号的特征参数与编码常量之间的协议关系。
本实施例通过下述方法将待传输数据信息编码到第二音频信号中：
将待传输数据信息转换为高低电平信号，该高低电平信号对应为二进制编码；
根据预设音频信号的特征参数与编码常量之间的协议关系，获取第一音频信号的特征参数对应的编码常量；
根据编码常量与二进制编码之间的对应关系，将待传输数据信息编码到第二音频信号中。其中，本实施例的编码常量可以理解为：一位二进制编码1或0对应的声波时长；假设待传输数据信息转换的高低电平信号为111001，编码常量为10毫秒，则该待传输数据信息编码到第二音频信号中，对应为连续30毫秒的高分贝音频信号、连续20毫秒的低分贝音频信号和10毫秒的高分贝音频信号。
需要说明的是，由于在将待传输数据信息编码到第二音频信号中时，需要将待传输数据信息转换为二进制编码，为了使音频终端能够准确识别传输信息，可以在预设的通讯协议中约定数据传输协议，如设置数据标识位，利用数据标识位标识传输的数据信息，如设置数据长度标识和数据体，利用数据长度标识指示传输数据的长度信息，利用数据 体携带数据信息。实际应用中可以设置数据标识位携带设定长度的高电平，如设置数据标识位携带3比特位的高电平，当音频设备解码第二音频信号后，利用数据标识位获取传输数据。
在本发明的一些实施例中，为保证数据传输的安全性和可靠性，在进行数据传输时，检测向音频设备发送的第一音频信号的环境噪声，根据环境噪声向音频设备发送第一音频信号，并获取第一音频信号的特征参数，此时获取的第一音频信号的特征参数可以理解为振幅、频率等基本特征参数，根据获取的第一音频信号的特征参数获取第二音频信号的特征参数。
在本发明的一些实施例中，智能终端利用麦克风等设备检测环境噪声，智能终端生成区别于环境噪声的第一音频信号，如智能终端利用频率、振幅等基本特征参数使第一音频信号区别于环境噪声，使得音频设备可以在该环境噪声中接收并识别第一音频信号；智能终端将生成的第一音频信号发送给音频设备，并根据第一音频信号的频率、振幅等基本特征参数生成第二音频信号，使音频设备可以在该环境噪声中接收并识别第二音频信号。
本实施例所传输的数据信息可以包括数据文件信息、文本信息、指令信息等。在实际应用中，可以根据应用场景设置所传输的数据信息。例如，在智能终端控制音频设备联网时，向音频设备发送开启无线网络功能的控制指令，以及对应无线网络的账户名称和账户密码作为待传输数据信息，利用上述编码规则将待传输数据信号编码到第二音频信号中。
为详细说明本实施例中的音频设备与智能终端之间的数据传输过程，本发明通过下述实施例具体说明。
为便于描述，本实施例以音频设备为音响，智能终端为手机为例。其中音响设置有多个麦克风，用于拾取音响周围设定范围内的声音信号；在音响顶部的四周均匀布置至少三个麦克风，图4示例性示出在音响顶部的四周均匀布置四个麦克风的示意图；手机设置有麦克风和扬声器，利用手机的麦克风检测环境噪声，利用手机的扬声器发送音频信号。

本实施例利用手机的麦克风检测环境噪声，生成区别于环境噪声的第一音频信号并利用手机扬声器发送给音响。其中，手机发送的第一音频信号包括多次音频信号，例如包括三次音频信号。
S520，音响接收第一音频信号。
音响在接收到第一音频信号时，对第一音频信号进行处理，得到第一音频信号的特征参数，特征参数包括第一音频信号的频率、振幅。
由于本实施例的第一音频信号为多次音频信号，每次音频信号表现为一段声音信号，当接收到的第一音频信号后，判断第一音频信号中的各次音频信号的频率和振幅是否相同，根据判断结果决定是否接收手机发送的第二音频信号。
根据本发明的实施例，音响在接收第一音频信号时，根据第一音频信号的声波(或波形)可以得到第一音频信号的频率和振幅，在将第一音频信号转换为电信号时，可以得到该电信号中高电平的持续时长。
其中，将第一音频信号转换为电信号的方法可以为：由于第一音频信号为声音信号，当有声波信号出现时，对应该电信号为高电平，当声波信号不出现，对应该电信号为低电平。例如音响将第一音频信号转换的电信号如图2所示，第一音频信号的电信号包括三组高低电平信号。在第一音频信号的各次音频信号的频率和振幅都一致的情况下，为提高音响对音频信号的处理效率，音响在获取到第一个高低电平时，开始启动判断机制，获取接收到的第二个高电平与第二个低电平的持续时长，以及第三个高电平和第三个低电平的持续时长。判断第二个高电平、第三个高电平和第二个低电平、第三个低电平对应的持续时长是否与第一个高电平、第一个低电平相同，如果都相同，准备接收手机发送的第二音频信号，否则，不接收手机发送的第二音频信号。
S530，手机发送第二音频信号。
手机将待传输数据信息转换为高低电平信号，该高低电平信号对应为二进制编码，根据第一音频信号的特征参数与编码常量之间的协议关系，获取第一音频信号的特征参数对应的编码常量，根据编码常量与二进制编码之间的对应关系，将待传输的数据信息编码到第二音频信号中并利用手机扬声器发送给音响。
S540，音响接收第二音频信号。
音响在接收第二音频信号时，对第二音频信号进行处理，得到第二音频信号的特征参数，第二音频信号的特征参数也包括频率和振幅。
当第二音频信号的特征参数与第一音频信号的特征参数一致时，即第二音频信号的频率和振幅分别与第一音频信号的频率和振幅一致时，根据预设音频信号的特征参数与解码常量之间的协议关系，获取第一音频信号的特征参数对应的解码常量，根据解码常量与二进制编码之间的对应关系，对第二音频信号中编码的数据信息进行解码，得到第二音频信号中编码的数据信息，音响根据接收到的数据信息进行相应的处理。
