 本发明的实施方式
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作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。
如图1所示，图1为一个实施例中触觉振动自调节方法的流程示意图，本发明提供的触觉振动自调节方法的步骤包括：
步骤102，获取当前应用场景，根据当前应用场景从存储介质中调取对应的待调节振动波形，对待调节振动波形进行分帧处理，获取包括多个振动信号帧的振动帧信号。
其中，待调节振动波形是指当前需要调节振动幅度的振动波形。振动帧信号是指待调节振动波形经过分帧处理后，由至少一个信号帧组成的振动信号。
如图2所示，图2为一个实施例中触觉振动自调节装置的结构框图，该触觉振动自调节装置包括储存器21、信号处理器22、振动器23，其中信号处理器分别与储存器以及振动器相连。在本实施例中，为适应不同的使用场景，提前在设备储存器中录入了对应的待调节振动波形。具体的，可以以使用者的年龄为储存标准储存相应的待调节振动波形，或者以使用场地为储存标准储存相应的待调节振动波形。
在本实施例中，分帧是通过用可移动的有限长度窗口进行加权的方法来实现。因此需确定窗口长度以及窗口每次往右移动的长度，窗口长度以及窗口每次往右移动的长度可以根据待调节波形的时长适应性的设置。
进一步的，为了使帧与帧之间平滑过渡，保持连续性，前一帧和后一帧之间存在交叠部分，该交叠部分称为帧移，帧移与每一帧的时长之比通常取为0-1/2。
步骤104，提取位于振动帧信号端部的至少一个振动信号帧，获取至少一个振动信号帧的原始均衡电压。
如果对整段振动帧信号进行修正，将导致信号在传输过程中与原有信号相比出现较大程度的偏差，即出现大幅度信号失真现象。因此在本实施例中，只提取振动帧信号端部的信号帧。可选的，可以提取振动帧信号端部的一帧或者预设数量的信号帧进行，例如3帧。提取帧的数量根据具体根据原始均衡电压大于设备最大输出电压的情况而定。
在一个实施例中，通过将位于端部位置的振动帧信号作为输入量，输入到均衡算法数学模型中并经过计算即可得到原始均衡电压。其中，均衡算法可以通过实际振动系统的运动微分方程推导得到，也可以通过数值建模形式得到，是一种常用的仿真手段。
步骤106，判断原始均衡电压是否大于预设阈值，若是，执行步骤108。若否，则执行步骤112。
在本实施例中，预设阈值设置为设备的最大输出电压。
受设备性能影响，不同振动播放设备的电压输出限制不同。当获取到的待调节振动波形的原始均衡电压大于电压输出限制时，在驱动器输出触觉振动时会出现振动幅度偏小的问题，因此需要对原始均衡电压大于预设阈值部分进行调节。
步骤108，根据预设算法对原始均衡电压进行修正，获取修正均衡电压。
可以理解的是，修正均衡电压应小于或等于设备最大输出电压。在一个实施例中，可以通过含有单调递减区间的函数将原始均衡电压衰减至修正均衡电压。应当说明的是，本实施例中的具有单调递减区间的函数包括但不限于以下任意一种：线性函数、多次函数、幂函数、指数函数、对数函数、三角函数、反三角函数。
步骤110，根据修正均衡电压获取已调节振动波形，驱动振动器以已调节振动波形输出触觉振动。
具体的，基于修正均衡电压生成端部位置的已调解端部振动波形，同时获取待调节振动波形中包括未调节中间部振动波形、未调节端部振动波形等振动波形。其中，未调节中间部振动波形、未调节端部振动波形和已调解端部振动波形的时长应等于未调节振动波形。对未调节中间部振动波形、未调节端部振动波形和已调解端部振动波形进行合成即可得到已调节振动波形。
步骤112，将待调节振动波形作为输出振动波形，驱动振动器以输出振动波形输出触觉振动。
上述触觉振动自调节方法，通过对待调节振动波形进行分帧处理，获得振动帧信号，并获取其中端部位置至少一个振动信号帧的原始均衡电压；再根据预设算法对该原始均衡电压进行修正，获取修正均衡电压并得到已调节振动波形，最后通过驱动振动器以已调节振动波形输出触觉振动。由于本发明能针对实际输出设备的输出能力对振动波形进行自适应调节，能够有效降低同一的振动波形在不同输出设备中输出的振动触觉的差异。
如图3所示，图3为一个实施例中提取振动帧信号前端以及后端振动信号帧的流程示意图，本发明提供的提取振动帧信号前端以及后端振动信号帧的步骤包括：
步骤302，获取待调节振动波形，对待调节振动波形进行分帧处理，获取包括多个振动信号帧的振动帧信号。
在一个具体的实施场景中，步骤302与本发明提供的触觉振动自调节方法中的步骤102、基本一致，此处不再进行赘述。
步骤304，提取至少一个位于振动帧信号前端的振动信号帧，以及至少一个位于振动帧信号末端的振动信号帧。
由于需要增加或减小触觉振动的振动幅度，会常出现在待调节振动波形的播放起始段或播放结束段的所需原始均衡电压大于设备最大输出电压的情况，因此在本实施例中，为尽可能让播放的触觉振动与设计的触觉振动一致，同时保证触觉振动的失真较小，选择振动帧信号前端的振动信号帧以及振动帧信号末端的振动信号帧。
步骤306，获取对应于至少一个位于振动帧信号前端的振动信号帧的原始初始电压和对应于至少一个位于振动帧信号末端的振动信号帧的原始终止电压。
在一个实施例中，通过将位于振动帧信号前端的振动信号以及末端的振动信号作为输入量，输入到均衡算法数学模型中并经过计算即可得到对应的原始初始电压和原始终止电压。
步骤308，判断原始初始电压是否大于第一预设电压阈值；和/或判断原始终止电压是否大于第二预设电压阈值。若是，则执行步骤310或步骤312。若否，则执行步骤316。
其中，第一预设电压阈值和第二预设电压阈值都应该设置为小于等于设备最大输出电压，例如9V。进一步的，第一预设电压阈值和第二预设电压阈值可以相同。
在本实施例中，根据判断段结果选择预设的算法模式对原始初始电压和/或原始终止电压进行修正。具体的，当只满足原始初始电压大于第一预设电压阈值时，启动快起模式，仅对原始初始电压进行修正。当只满足原始终止电压大于第二预设电压阈值时，启动快停模式，仅对原始终止电压进行修正。当原始初始电压大于第一预设电压阈值且原始终止电压大于第二预设电压阈值时，启动快起且快停模式，对原始初始电压与原始终止电压进行修正。当原始初始小电压大于第一预设电压阈值且原始终止电压小于第二预设电压阈值时，可以将待调节振动波形作为最终输出振动波形，以驱动振动器输出触觉振动。
步骤310，降低原始初始电压和/或原始终止电压的波形幅值，得到修正初始电压和/或修正终止电压。
在一个实施例中，通过含有单调递减区间的函数确定刹车电压；基于该刹车电压对原始初始电压和/或原始终止电压的波形幅值进行修正，生成波形幅值低于原始振动幅值的已调解振动波形，将该刹车电压的末端电压作为修正初始电压和/或修正终止电压。
步骤312，调整原始初始电压和/或原始终止电压的波形频率，得到修正初始电压和/或修正终止电压。
在一个实施例中，通过获取马达的共振频率，基于含有单调递减区间的函数确定波形频率与马达的共振频率相等的刹车电压，将该刹车电压的波形频率作为修正初始电压和/或修正终止电压的波形频率。
其中，步骤310与步骤312均能实现得到修正初始电压和/或修正终止电压，可选择其中任一步骤。
步骤314，用修正初始电压替换原始初始电压；和/或用修正终止电压替换原始终止电压；对替换后的待调节振动波形进行合成处理，得到已调解振动波形；驱动振动器以已调节振动波形输出触觉振动。
在本实施例中，基于修正初始电压生成前端部的已调解振动波形，和/或基于修正终止电压生成末端部的已调解振动波形。对前端部的已调解振动波形和/或末端部的已调解振动波形，以及中间部的未调节振动波形进行合成即可得到所需的已调解振动波形。
具体的，在进行合成操作时，首先对每一帧通过滤波算法进行小波域的滤波，然后把每一帧去噪处理后的信号通过线性重叠相加法进行合并，得到已调解振动波形。
步骤316，将待调节振动波形作为输出振动波形，驱动振动器以输出振动波形输出触觉振动。
上述触觉振动自调节方法，通过对位于信号帧前端以及信号帧后端的帧信号的原始均衡电压进行修正，使其小于设备的最大输出电压，具体通过降低原始初始电压和/或原始终止电压的波形幅值，或调整原始初始电压和/或原始终止电压的波形频率来实现。因此本发明能实现在尽可能让播放的触觉振动与设计的触觉振动一致的同时，避免了较大程度的失真。
在一个实施例中，如图4所示，提出了一种触觉振动自调节装置，该装置包括：
第一获取模块402，用于获取待调节振动波形，对待调节振动波形进行分帧处理，获取包括多个振动信号帧的振动帧信号；
