图1是根据本公开的一种实施方式提供的触觉信号生成方法的流程图。如图1所示，本公开提供的方法可以包括步骤11～步骤14。
在步骤11中，确定与待处理的目标音频信号对应的目标频域信号。
其中，目标音频信号为时域音频信号。
示例地，对目标音频信号进行短时傅里叶变换(Fast Fourier Transform，FFT)处理，可以得到目标频域信号。其中，FFT点数可以根据采样率和计算复杂度选取，例如选择512点或256点，相应地，能够得到257个或129个频域信号，作为目标频域信号。
在步骤12中，将目标频域信号分为多个子带，并确定每一子带的目标能量值。
其中，对目标频域信号进行划分时，划分的子带的数量可以根据实际的需求进行选取。例如，可以根据触觉反馈、计算复杂度等的需求选取(如3-7之间的整数)。
在划分完成后，可以根据分带后的数据，确定每一子带的目标能量值。
在一种可能的实施方式中，步骤12可以包括以下步骤：
将目标频域信号分为多个子带；
确定每一子带的瞬时能量值；
对子带的瞬时能量值进行均值滤波处理，得到每一子带的滤波能量值；
对滤波能量值进行归一化处理，得到每一子带的目标能量值。
将目标频域信号分为多个子带后，可以首先计算每个子带在指定时刻的能量和，也就是子带的瞬时能量值。
通常情况下，瞬时能量值的数据跳跃性较强，可能不利于后续的数据处理，因此，为了数据的平滑性，可以使用均值滤波的方式对其进行处理。例如，可以对分带后的目标频域信号的瞬时能量做时间维度上的均值滤波，得 到由每一子带的滤波能量值构成的子带能量包络。其中，滤波器长度可以根据响应延迟和包络平滑度按需选取，滤波器长度越长，子带能量包络的就越平滑，相应地，由音频信号向触觉信号转换的响应延迟就越大。示例地，滤波器长度可以为5，相应的响应延迟将在6ms以内。
在得到每一子带的滤波能量值后，可以对滤波能量值进行归一化处理。其中，归一化处理可以参考下述方式：
根据每一子带的滤波能量值，也就是子带能量包络，计算瞬时增益值；
采用长时平滑的方法，得到每个子带的子带能量包络噪音水平，并且，当子带的瞬时增益值小于或等于该噪音水平时，不对瞬时增益值进行额外处理，当子带的瞬时增益值小于或等于该噪音水平时，将子带音频能量包络的增益值在时间维度上做平滑，其中，平滑的速度可以取决于上一帧的增益和当前的瞬时增益值的比值；
最后，将上述增益值(更新后的增益值，或者，未更新的增益值)与子带能量包络上的数据按序做乘法运算，得到归一化后的子带能量包络，也就是每个子带的目标能量值。
示例地，上一帧t-1的增益和当前帧t所求的瞬时增益值之间的比值r大于4时，第t帧的增益值可以为第t-1帧的增益值的0.75倍；当比值r大于2且小于4时，第t帧的增益值可以为第t-1帧的增益值的0.81倍；当比值r大于1且小于2时，第t帧的增益值可以为第t-1帧的增益值的0.92倍；当比值r小于0.2时，第t帧的增益值可以为第t-1帧的增益值的1.3倍；当比值r大于0.2且小于0.5时，第t帧的增益值可以为第t-1帧的增益值的1.1倍；当比值r大于0.5且小于1时，第t帧的增益值可以为第t-1帧的增益值的1.02倍。
通过上述方式，将各个子带的音频信号能量在时间维度上进行归一化，能够保证不同音频转换的触觉信号不受音频本身音量的影响，也就是说，为 音频向触觉的转换提供一个统一的接口，以整体调节触觉的效果，进而，用户可以根据自己的需求，通过这个统一接口，整体调整触觉反馈设备(例如，振动电机)输出的触觉强度，无需再针对每个音频文件手动调整，能够提升用户的使用体验。
在步骤13中，从多个备选映射频率组合中，确定出能够在触觉反馈设备上得到最佳触觉反馈效果的目标频率组合。
在本公开中，触觉信号可以为振动信号，相应地，触觉反馈设备可以为振动电机。
在一种可能的实施方式中，步骤13可以包括以下步骤：
获取样本数据；
确定触觉强度与频率之间的对应关系；
针对每一备选映射频率组合，根据频率参考值、触觉强度参考值和对应关系，确定备选映射频率组合的误差值；
将最小的误差值对应的备选映射频率组合确定为目标频率组合。
其中，样本数据包括基于多个音频信号样本所确定的频率参考值和触觉强度参考值。
在本公开中，可以收集多个期望得到理想触觉反馈效果的音频信号样本作为样本数据。同时，可以对触觉反馈设备的频率响应曲线进行非线性拟合，以得到触觉强度与频率之间的函数关系，也就是触觉强度与频率之间的对应关系。
进而，可以对音频信号样本进行如上文所述的对目标音频信号的处理，得到音频信号样本对应的子带能量值。
频率参考值可以是根据实际需求选取的，用于进行触觉强度的数据标定。例如，频率参考值可以为触觉反馈设备的共振频率。其中，可以将样本数据中的所有子带能量值都映射到频率参考值，以生成用于进行触觉强度标定的 触觉信号，并且，可以将上述触觉信号接入触觉反馈设备，再由标定人员根据实时的触觉反馈，确定各音频信号对应的标定参数，并得到每条音频的触觉强度参考值。
示例地，触觉信号和触觉强度参考值可以参考如下公式计算：

其中，St为t时刻用于进行触觉强度标定的触觉信号，St是单一频率的正弦波信号，其频率为2*π*f0/fs，f0为频率参考值，fs为采样率，α为标定参数，E为音频信号样本对应的子带能量值，t为0-T的时间帧数。示例地，若触觉信号为振动信号，则触觉强度参考值Ht可以表征振动强度。
触觉强度参考值Ht的计算思路在于，以2*π*f0/fs为频率，以标定参数α与音频信号样本对应的子带能量值的乘积为幅度，生成的正弦波在时间维上的平均幅度值。
在确定好上述参数后，就可以针对备选映射频率组合进行选择。
在一种可能的实施方式中，备选映射频率组合可以通过如下方式确定：
根据触觉强度与频率之间的对应关系，确定能够使触觉强度均匀分布的多个频率，作为备选映射频率组合。
也就是说，根据前述步骤中确定出的触觉强度与频率之前的对应关系，可以从中选择多组频率，作为备选映射频率，并且，选择时应当保证选出的一组频率使触觉强度均匀分布。
在另一种可能的实施方式中，备选映射频率组合可以通过如下方式确定：
根据触觉反馈设备的共振频率，确定包含共振频率在内的目标频率区间，并从目标频率区间中确定出一组频率作为备选映射频率组合。
也就是说，将触觉反馈设备的共振频率作为频率参考值。示例地，可以选取共振频率上、下30Hz构成目标频率区间，进而从中选择多组频率，作为备选映射频率。
由于在共振频率下，触觉反馈设备的电能消耗是最小的，因此，将触觉反馈设备的共振频率作为优化目标，能够有效降低触觉反馈设备的功耗。
在一种可能的实施方式中，根据频率参考值、触觉强度参考值和对应关系，确定备选映射频率组合的误差值，可以包括以下步骤：
根据备选映射频率组合和对应关系，确定备选映射频率组合对应的第一触觉强度；
确定第一触觉强度与触觉强度参考值之间的均方误差，作为第一均方误差；
确定备选映射频率组合与频率参考值之间的均方误差，作为第二均方误差；
根据第一均方误差和第二均方误差之和，确定备选映射频率组合的误差值。
示例地，第一触觉强度可以通过如下公式计算：

其中，Sn为t时刻备选映射频率组合对应的触觉信号，其频率为2*π*f/fs，fs为采样率，Fn为备选映射频率组合(即，当前计算所当前计算所针对的备选映射频率组合)，α为标定参数，E为音频信号样本对应的子带能量值，t为0-T的时间帧数，G(f)为触觉强度与频率之间的对应关系。第一触觉强度Hn的计算思路与触觉强度参考值Ht的计算思路一致，此处不赘述。
示例地，可以通过如下公式确定备选映射频率组合的误差值cost：
其中，Hn、Ht、f、f0、Fn的含义在前文提供的公式中已给出，此处不再重复叙述。在上述计算式中，等式右侧的左半部分用于计算第一均方误差，等式右侧右半部分用于计算第二均方误差。
从而，基于上述公式，针对每一备选映射频率组合进行计算，可以得到每一备选映射频率组合对应的误差值。
这样，将触觉强度参考值和频率参考值引入误差值，并将误差值作为触觉反馈效果的评判标准，通过使二者的差距整体最小这一目的选择目标频率组合，既能使触觉反馈效果符合预期值，又能降低触觉反馈设备的功耗，有利于达到最优的触觉反馈效果。
在步骤14中，根据目标频率组合，得到用于进行触觉反馈的目标触觉信号。
在一种可能的实施方式中，步骤14可以包括以下步骤：
根据目标频率组合，分别将每一子带的目标能量值映射为触觉信号分量。
对触觉信号分量进行叠加，得到用于进行触觉反馈的目标触觉信号。
其中，将各子带的目标能量值映射为触觉信号分量，可以通过如下方式实现：
针对每一子带的目标能量值，根据目标能量值和目标能量值在目标频率组合中对应的目标频率，生成频率为目标频率、且能量为目标能量值的正弦波信号，作为该目标能量值对应的触觉信号分量。
此后，将得到的触觉信号分量进行叠加，既可以得到用于进行触觉反馈的目标触觉信号，进而，将该目标触觉信号发送给触觉反馈设备，由触觉反馈设备提供触觉反馈。
示例地，可以按照下述公式计算用于进行触觉反馈的目标触觉信号：
其中，H(t)为t时刻用于进行触觉反馈的目标触觉信号，Fn为目标频率组合，E(f,t)为目标频率组合中的频率f对应子带在t时刻的目标能量值。
通过上述技术方案，确定与待处理的目标音频信号对应的目标频域信号，将目标频域信号分为多个子带，并确定每一子带的目标能量值，从多个备选映射频率组合中，确定出能够在触觉反馈设备上得到最佳触觉反馈效果的目标频率组合，根据目标频率组合，得到用于进行触觉反馈的目标触觉信号。由此，能够自动地选取效果最佳的映射频率组合，而无需人为手动调节，反馈准确度及效率更高，且极大地减少了人力成本。
