为了更清楚地说明本申请实施例的技术方法，下面将对实施例中所需使用的附图作以简单地介绍。
图1a为X轴线性马达的结构以及应用示例图；
图1b为Z轴线性马达的结构以及应用示例图；
图2为本申请实施例公开的一种电子设备的结构示意图；
图3a为本申请实施例提供的线性马达的振动波形调整方法应用的软件架构示例图；

具体实施方式
本申请说明书和权利要求书及附图说明中的术语“第一”、“第二”和“第三”等是用于区别不同对象，而不是用于限定特定顺序。
在本申请中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
线性马达设置在电子设备中，用于通过振动使得电子设备输出振感。在电子设备的不同场景下，线性马达被控制发生振动产生不同的振动效果，使得用户感知到振感，以提示用户或对用户操作进行反馈，具体如下：
1、对应于不同的业务场景(例如：时间提醒，接收信息，来电，闹钟，游戏等)，可以对应不同的振动效果。
2、作为对触摸的反馈。例如，作用于不同应用(例如拍照，音频播放等)的触摸操作，可以对应不同的振动效果。作用于显示屏不同区域的触摸操作，也可对应不同的振动效果。
电子设备中常用的线性马达包括X轴线性马达(又称方形或横向线性马达)以及Z轴线性马达(又称圆形或纵向线性马达)两种。图1a为X轴线性马达的结构以及应用示例，图1b为Z轴线性马达的结构以及应用示例。
如图1a所示，X轴线性马达的外观呈长条或方块形，假设X轴为水平轴，Y轴为竖直轴，Z轴为垂直于X轴和Y轴的垂直轴，则依据摆放方向，X轴线性马达的动子可以在X 轴或Y轴方向运动，可以做到更长的行程。X轴线性马达在电子设备中沿X轴方向安装，则能够提供X轴方向的振感，若沿Y轴方向安装，则能提供Y轴方向的振感。
如图1b所示，Z轴线性马达的外观呈圆柱形，动子可以在Z轴方向运动。Z轴线性马达设置在电子设备中，能够带来沿电子设备的厚度方向的振感。
线性马达的谐振频率是线性马达运行的关键参数，谐振频率也称共振频率，是指一物理***(指线性马达)在特定频率下，比其他频率以更大的振幅做振动的情形，此特定频率被称之为共振频率。在共振频率下，很小的驱动力便可使线性马达产生很大的振动，因此，一般驱动线性马达以谐振频率运行。
振动描述文件是控制线性马达发生振动的关键要素之一：振动描述文件用于描述线性马达的振动波形，振动波形指示马达振动过程中的各项振动参数，例如振幅和频率等。
可见，振动描述文件的作用是指示马达如何进行振动，因此用户可以通过振动描述文件配置预期的振动效果。而实际中，线性马达是振动的实施主体，因此，振动效果与线性马达的属性相关，所以，虽然基于预期的振动效果配置振动描述文件，但振动描述文件控制的线性马达产生的振动，不一定能够实现预期的振动效果。
基于上述不同种类的线性马达的特点，申请人在研究的过程中发现：线性马达不能提供预期的振动效果主要体现在：
不同种的线性马达或者同种线性马达，其谐振频率是有差异的。不同谐振频率的线性马达均会应用到电子设备中，因此，同一种振动描述文件描述的瞬态驱动波形的频率，并不能与实施振动的每一种线性马达的谐振频率相适配。例如：振动描述文件定义频率为230hz的振动波形，实施振动的线性马达的谐振频率为150hz和230hz。如前所述，线性马达的谐振频率为150hz，线性马达输出频率为150hz的驱动波形，才能保证在很小的驱动力促使线性马达产生很大的振动。振动描述文件定义的振动波形的频率为230hz，谐振频率为150hz的线性马达输出频率为230hz振动波形，会使得线性马达输出的振感达不到要求。因此，有必要对振动描述文件描述的振动波形进行调整，使振动波形与实施振动的线性马达的每一种谐振频率适配，以保证获得预期的振动效果，并获得预期的振感。
本申请实施例公开的线性马达的振动波形调整方法，基于实施振动的线性马达的特点，对振动描述文件描述的振动波形进行调整，使振动波形与实施振动的线性马达的谐振频率适配，以保证获得预期的振动效果以及振感。

本申请实施例所述的线性马达的驱动波形的调整方法，可以应用在图3a中的波形处理模块。以下将对线性马达的驱动波形的调整方法进行详细说明。
图4示出了一种驱动波形的调整方法，应用于电子设备，电子设备包括线性马达。该驱动波形的调整方法包括：
S401、获取振动描述文件。
振动描述文件包括多种振动参数，通过解析振动描述文件，可得到振动描述文件包括的每一种振动参数，且利用振动参数可生成线性马达的振动波形。线性马达的振动波形可以理解为一种位移码流，体现出线性马达在不同时间点下的位移。
如前所述，X轴线性马达的动子可以在X轴或Y轴方向运动，Z轴线性马达的动子可以在Z轴方向运动。因此，无论是哪一种线性马达，线性马达受波形驱动的运行，都是指线性马达的动子在对应轴(X轴、Y轴或Z轴)上的运行，动子在对应轴上运动的表现形式就是动子在不同时刻沿对应轴发生位移变化，通过动子沿在不同时刻的位移变化，带来被用户感受到的振感。
振动描述文件中的振动参数可以包括但不限于：强度、锐度(也称为频率)、波形类型、启动时间以及停止时间。
S402、识别振动描述文件描述的波形类型。
若振动描述文件描述的波形类型为瞬态波形，则执行步骤S203。
振动描述文件的振动参数包括波形类型，通过分析波形类型，可以确定出振动描述文件描述的是稳态波形还是瞬态波形。
可以理解的是：稳态波形为驱动线性马达经历上升阶段、稳定振动阶段和停止阶段的振动波形。上升阶段、稳定振动阶段和停止阶段为线性马达从开始振动到结束振动经历的三个阶段。在上升阶段，线性马达的振动形式表现为自由衰减振动伴随强迫振动，在稳定振动阶段线性马达的振动形式表现为等幅的稳态强迫振动，在停止阶段线性马达的振动形式表现为自由衰减振动。
瞬态波形为驱动线性马达仅经历上升阶段的振动波形。
S403、按照与线性马达的谐振频率相适配的波形数组的参数，生成多个半周期波形，并组合生成的多个半周期波形，得到振动描述文件描述的瞬态波形。
振动描述文件包括的振动参数，定义出要需要生成的振动波形。因此，基于振动描述文件描述的瞬态波形的振动参数，可以生成满足振动参数需求的振动波形。例如：振动描述文件定义的振动参数包括：频率为230hz，基于该振动参数，可以生成频率为230hz的振动波形。
但是，如前所述，由于不同的线性马达，其适配的频率(也称谐振频率)是有差异性的。振动描述文件描述的瞬态波形的频率，在与线性马达的谐振频率不匹配时，会带来线 性马达振感达不到振动描述文件描述的瞬态波形振感要求。因此，需要处理振动描述文件描述的瞬态波形的振动参数，生成与线性马达的适配的每一种谐振频率相匹配的驱动波形。也可以理解成：需要屏蔽掉线性马达的谐振频率的差异，控制多个不同谐振频率的线性马达，均能输出同种振动描述文件描述的瞬态波形。例如：针对振动描述文件定义频率为230hz的振动波形，需要由谐振频率为230hz的线性马达以及150hz的线性马达来输出。
为了保证振动描述文件描述的瞬态波形，可以由不同谐振频率的线性马达来输出，预先定义出线性马达的每一种谐振频率对应的波形数组，并存储在电子设备的内部存储器。波形数组包括：多个半周期波形，每个半周期波形是以瞬态波形的半个周期为拆分单位，对线性马达谐振频率适配的瞬态波形进行拆分得到。当然，在电子设备的内部存储器存***形数组，是存储用于生成每半个周期的波形的频率和振幅。
另外，振动描述文件描述的瞬态波形周期是固定的，例如，一个瞬态波形包括3个周期的波形，每种谐振频率的线性马达的波形数组则会包括：6个半周期波形对应的频率和振幅。
在振动描述文件描述的波形类型为瞬态波形的情况下，从预先存储的每一种谐振频率对应的波形数组中，筛选出电子设备中线性马达的谐振频率对应的波形数组，按照波形数组中指示的多个半周期波形的频率和振幅，生成每一个半周期波形，再组合生成的每一个半周期波形，得到瞬态波形。
图5示出了另一种驱动波形的调整方法，也应用于电子设备，电子设备包括线性马达。该驱动波形的调整方法包括：
S501、获取振动描述文件。
S502、识别振动描述文件描述的波形类型。
若振动描述文件描述的波形类型为瞬态波形，则执行步骤S503。
步骤S501和步骤S502的具体内容，可参见图4对应实施例中步骤S501和步骤S502的内容。
S503、按照振动描述文件描述的瞬态波形的振动参数，从预先存储的多个驱动波形中，选择与线性马达的谐振频率相匹配的驱动波形。
可以理解的是：从预先存储的多个驱动波形中，选择与线性马达的谐振频率相匹配的驱动波形，也需要符合振动描述文件描述的瞬态波形的振动参数要求。这种预先存储多个驱动波形，按照振动描述文件描述的瞬态波形的振动参数和线性马达的谐振频率的要求，选择出一个驱动波形来驱动线性马达的方式，也可以实现屏蔽掉线性马达的谐振频率的差异性，当然，由于是直接选择，能够做到得到驱动波形的效率更高。
由于线性马达的谐振频率需求是有限的，不同的线性马达需要不同谐振频率的驱动波形。因此，可以预先生成适应不同谐振频率的线性马达的驱动波形，存储至电子设备的内部存储器，这些预先生成的驱动波形，就称之为原子驱动波形。
原子驱动波形的生成方式，由下述三种：
第一种，将线性马达所涉的每一种谐振频率的驱动波形，均作为原子驱动波形。如此，可以保证线性马达的每一种谐振频率，均能从存储的原子驱动波形中，找到相适配的原子驱动波动。但是本生成方式需要占用较大的存储空间。
第二种，将线性马达所涉的频率范围内中的一段频率范围中的每一个频率的驱动波形，作为原子驱动波形，例如：线性马达所涉的所有频率的频率范围为70hz到185hz，将本频率范围内的每一个频率的驱动波形，作为原子驱动波形；或者将70hz到185hz中的165hz到175hz中的每一个频率的驱动波形，作为原子驱动波形。当然，线性马达所涉的频率范围内中的一段频率范围的选定标准也可以是：命中率较高的频率范围，命中率较高同样指代被多数线性马达所采用的频率组成的范围。本生成方式生成的原子驱动波形数量相对第一种较少，不需要占用较大的存储空间，随之带来的是有可能存在无法找到线性马达的一种谐振频率对应的原子驱动波形。
第三种，将命中率较高的线性马达的谐振频率的驱动波形，作为原子驱动波形。命中率较高的谐振频率是指：在一系列的线性马达的谐振频率中，属于被多数线性马达所采用的谐振频率。例如：频率范围由70hz到185hz中，70、80、90、100、120、130、150和170这几个频率属于被多数线性马达所设定的谐振频率，会被设定为命中率较高的谐振频率。本生成方式在第二种的基础上，又进一步降低了存储空间的要求，同样无法找到线性马达的一种谐振频率对应的原子驱动波形的概率也增加了。
振动描述文件描述的瞬态波形频率是多样化的，即可以要求线性马达按照不同频率的波形来运行。基于此，在每一种原子驱动波形要包含的驱动波形的数量为多个，每一个驱动波形适配振动描述文件描述的瞬态波形的一种频率需求。例如：谐振频率为165hz的线性马达的原子驱动波形包括：频率为80hz的瞬态波形对应的驱动波形，频率为81hz的瞬态波形对应的驱动波形，频率为82hz的瞬态波形对应的驱动波形……
由上述内容可以看出：预先存储了适配线性马达不同谐振频率的原子驱动波形，因此，针对线性马达的每一种谐振频率，均能从存储的原子驱动波形中筛选出适配的原子驱动波形，并且，由于每一种原子驱动波形包括适配振动描述文件描述的瞬态波形的多种频率需求的驱动波形，因此，从筛选出适配的原子驱动波形中还可以进一步筛选出符合振动描述文件描述的瞬态波形的频率的驱动波形，如此，可以保证多种谐振频率的线性马达，可以输出同一个振动描述文件描述的瞬态波形，实现了对线性马达的谐振频率差异性的屏蔽。
基于上述内容可知：预先存储的多个驱动波形是以成组的方式进行保存的，一组驱动波形(也就是上述内容的一种原子驱动波形)对应线性马达的一种谐振频率；每一组驱动波形中包含至少一个驱动波形，每一个驱动波形适应于振动描述文件描述的瞬态波形的一种频率需求。
因此，步骤S503的一种实施方式为：
从多组驱动波形中，选择出频率与线性马达的谐振频率相匹配的一组驱动波形。
在一个示例中：振动描述文件的振动参数包括：振动频率为82hz；线性马达的谐振频率为165hz，按照本步骤的方式从多组驱动波形中，筛选出频率为165hz的一组驱动波形。
从选择出的一组驱动波形中，按照振动描述文件描述的瞬态波形的振动参数选择驱动波形。
续接上述示例：165hz的一组驱动波形包括多个驱动波形，每一个驱动波形是对应振动波形的一个频率，基于此，从165hz的一组驱动波形，筛选出频率为82hz的驱动波形。
在一个可能的实施方式中，采用上述提出的第二种和第三种原子驱动波形的生成方式生成原子驱动波形并存储，若在预先存储的多种原子驱动波形中，无法筛选出与线性马达的谐振频率相匹配的原子驱动波形，先从存储的多种原子驱动波形中，选择出与线性马达的谐振频率最接近的原子驱动波形，再从选择出的原子驱动波形中，按照振动描述文件描述的瞬态波形的振动参数选择驱动波形之后，按照线性马达的谐振频率，对选择出的驱动波形进行插值运算，得到与线性马达的谐振频率相匹配的驱动波形。与线性马达的谐振频率最接近，可以理解成频率与线性马达的谐振频率相同或者差值最小。
可选地，按照线性马达的谐振频率，对选择出的驱动波形进行插值运算，可以是采用重采样算法，对驱动波形进行采样，得到多个采样点的数值，再将多个采样点的数值***到驱动波形，完成对驱动波形的调整，得到与线性马达的谐振频率相匹配的驱动波形。
图6示出了另一种驱动波形的调整方法，也应用于电子设备，电子设备包括线性马达。该驱动波形的调整方法包括：
S601、获取振动描述文件。
S602、识别振动描述文件描述的波形类型。
若振动描述文件描述的波形类型为瞬态波形，则执行步骤S603。
步骤S601和步骤S602的具体内容，可参见图4对应实施例中步骤S401和步骤S402的内容。
S603、从预先存储的多个振动波形中，选择出符合振动描述文件描述的瞬态波形的振动参数要求的振动波形。
针对驱动线性马达按照不同频率下的振动波形进行输出的需求，预先存储多个频率的振动波形(为瞬态振动波形)，若振动描述文件描述的波形类型是瞬态波形，则按照振动描述文件描述的瞬态波形的振动参数，从预先存储的多个振动波形进行筛选，选择出与振动描述文件描述的瞬态波形的振动参数相匹配的振动波形。
S604、处理选择出的振动波形，得到与线性马达的谐振频率相匹配的驱动波形。
在选择出符合振动描述文件描述的瞬态波形的振动参数要求的振动波形后，利用反解马达电压驱动算法对振动波形进行反解运算，得到与线性马达的谐振频率相匹配的驱动波形。
在利用反解马达电压驱动算法对振动波形进行反解运算过程中，会按照线性马达的谐振频率对振动波形进行调整，以得到与线性马达的谐振频率相匹配的驱动波形。
反解马达电压驱动算法本身具有将振动波形反解成适配线性马达的谐振频率的功能，本实施例中，利用该算法的此种功能，实现了屏蔽掉线性马达的谐振频率差异性的目的。
还需要说明的是，若预先存储的多个频率的振动波形，不足以覆盖驱动线性马达按照所有频率的波形进行输出的需求，那在预先存储的多个振动波形中，无法选择出符合振动描述文件描述的瞬态波形的振动参数的振动波形，例如：预先存储了100hz到130hz的振 动波形，振动描述文件描述的瞬态波形的频率为135hz，针对振动描述文件描述的瞬态波形的135hz频率需求，在100hz到130hz的振动波形中不能找对等同频率的振动波形。
在此种情况下，需要从预先存储的多个振动波形中，选择出与振动描述文件描述的瞬态波形的振动参数最接近的振动波形，当然，这种最接近就是指代频率与振动描述文件描述的瞬态波形的振动参数差值最小。按照振动描述文件描述的瞬态波形的振动参数，对选择出的振动波形进行插值运算，以得到与振动描述文件描述的瞬态波形的振动参数相匹配的振动波形。
在一个可能的实施方式中，按照振动描述文件描述的瞬态波形的振动参数，对选择出的振动波形进行插值运算，可以是采用重采样算法，对振动波形进行采样，得到多个采样点的数值，再将多个采样点的数值***到振动波形，完成对振动波形的调整，得到与振动描述文件描述的瞬态波形的振动参数相匹配的振动波形。
还需要说明的是，振动波形处理模块和驱动波形处理模块采用图2、图3或者图4对应的三个实施例内容，生成驱动波形，其实现原理可以理解成：依据振动描述文件描述的振动参数以及线性马达的谐振频率，生成线性马达的驱动波形。如此可以看出：在振动描述文件描述的波形类型为瞬态波形的情况下，依据振动描述文件描述的振动参数以及线性马达的谐振频率，生成线性马达的驱动波形，保证了生成的线性马达的驱动波形能够适配该线性马达的谐振频率，实现了生成屏蔽马达差异性的瞬态波形来驱动线性马达。
