具体实施方式
下面将结合附图对本申请实施例中的技术方案进行清楚、详尽地描述。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；文本中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/ 或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为暗示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征，在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在本申请中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本申请所描述的实施例可以与其它实施例相结合。
本申请以下实施例中的术语“用户界面(user interface，UI)”，是应用程序或操作系统与用户之间进行交互和信息交换的介质接口，它实现信息的内部形式与用户可以接受形式之间的转换。用户界面是通过java、可扩展标记语言(extensible markup language，XML)等特定计算机语言编写的源代码，界面源代码在电子设备上经过解析，渲染，最终呈现为用户可以识别的内容。用户界面常用的表现形式是图形用户界面(graphic user interface，GUI)，是指采用图形方式显示的与计算机操作相关的用户界面。它可以是在电子设备的显示屏中显示的文本、图标、按钮、菜单、选项卡、文本框、对话框、状态栏、导航栏、Widget等可视的界面元素。
首先，介绍本申请涉及到的音乐相关概念，包括旋律、节奏和节拍等。这些概念在乐谱理论中有着的严格定义，具体如下：
旋律是音乐的首要要素，具体是指不同音高(音的高低)、不同时值(音的长短)的音符在一定的节拍中通过一定的节奏进行周旋与律动所形成的曲调就是旋律。
节奏是指，由音的长短与强弱拍位所构成的组织形态。具体的，在乐谱中，音的长短可由不同时值的音符来标识，例如全音符、二分音符、四分音符和八分音符等；音乐中有强拍和弱拍之分，强弱拍位一般由拍子的拍号来规定，例如四二拍、四三拍、八三拍、四四拍以及八六拍等等。
节拍是指，强拍和弱拍周期性地有规律地重复进行而形成了节拍。节拍具体是指在乐谱中每一小节的音符总长度，如一首音乐是四四拍，就是以4分音符为一拍，每小节4拍子，节拍的强弱交替规律是每小节第一拍强、第二拍弱、第三拍次强、第四拍弱，即强-弱-次强-弱。把音的长短与强弱拍位这两方面根据需要有机地组织起来，就形成了一首音乐的节奏。
可见，旋律包含了音的高低、音的长短和节拍三个因素。节奏只包含了音的长短和音的强弱(即节拍)两个方面的因素。虽然，旋律、节奏和节拍这三者不是同一层次上的概念，但这三者都能在移动程度上反应出一首音乐的特征。
根据上文所述，可知旋律、节奏以及节拍在乐谱理论中有着严格的定义。但是，从用户的听觉体验的角度出发，用户难以将一首音乐中的旋律、节奏以及节拍等严格区分。因此，本申请后续实施例中所述的音乐的特征既可以是上文严格定义的旋律、节奏或者节拍中的任意一种；或者音乐的特征还可以是在用户听觉体验基础上，从旋律、节奏或者节拍这三者中任意两种或多种结合得到的音乐特征。本申请实施例对音乐的特征的具体定义不 作限制，只要该音乐的特征在一定程度上能够反映出某段音乐的特征即可。
针对一首音乐，当电子设备采用算法实现从一首音乐中获取相对严格区分的旋律、节奏以及节拍等信息时，可以准确获取到任意一首音乐的特征。当采用非算法实现从一首音乐中获取旋律、节奏以及节拍等信息时，例如通过人耳感受音乐的旋律、节奏以及节拍等信息以获取音乐的特征时，这样的非算法实现获取音乐特征的方式，可以充分满足用户的听觉体验。因此考虑到既满足用户听觉体验并且降低对音乐文件的处理分析难度，本申请主要将音乐的特征定义为后者，即在用户听觉体验基础上，从旋律、节奏或者节拍这三者中任意一种或多种结合得到的音乐的特征。
在另一些实施例中，还可以将音乐的特征称为音乐的“拍子”，这里的“拍子”只是日常生活中，对音乐的特征进行描述的常用词汇。
考虑到音乐具有上述旋律、节奏以及节拍等特征，本申请提供了一种增强振动提示方法，主要结合音乐的特征并使用马达提供触觉体验，从而为用户带来了更加综合、全面的体验感。具体如下：
在本申请提供的增强振动提示方法中，电子设备可以先获取一首音乐的特征，并根据该首音乐的特征获取标准随振信息，该标准随振信息包括：驱动马达进行一次振动中，每个子段振动的起止时间，每个子段起止时间内的振动强度和频率等。之后，基于标准随振信息并通过以下任意一项或多项方法获取增强随振信息：将标准随振信息中每个子段起止时间内的振动强度增强至大于等于标准随振信息中振动强度的最大值；将标准随振信息中振动持续时间小于第一值的子段的持续时间延长；或者，将标准随振信息中相邻两个子段之间的间隔时间大于第二值的间隔缩短。最后，电子设备根据上述增强随振信息，驱动马达振动。
其中，标准随振信息主要作用为：基于该标准随振信息，获取到既与音乐的特征匹配，又能满足用户振动提示效果要求的增强随振信息，进而为用户提供既具有趣味性又具有强烈触感的振动体验。具体如下：
首先，标准随振信息是根据音乐的特点获取到与该音乐的旋律、节奏或节拍最匹配的振动信息。
其次，考虑到一首音乐存在节奏感较弱的部分、节奏段的部分或者节奏间隔长的部分，从而导致标准随振信息中所存在的弱振、短振以及相邻子段间隔过大而导致带给用户较弱的触觉体验的问题。因此，进一步根据该标准随振信息，通过增强弱振、延长短振以及缩短子段间隔来获取增强标准随振信息，从而为用户带来更强触觉体验的振动提示效果。
可见，获取标准随振信息是获取增强随振信息的一个过渡步骤。在基于标准随振信息得到的增强随振信息，不仅能在一定程度上保留音乐原本的特征，同时还在一定程度上提高振动提示效果，这样从两个维度考虑，可以充分满足用户对振动提示效果的要求。
总之，标准随振信息是用来为获取增强随振信息而到的一个中间结果，在本申请另一些实施例中，也可以通过其他方法实现从音乐的特帧中直接提取到最终的增强随振信息，无需获取标准随振信息这一中间结果。
可见，采用本申请提供的增强振动提示方法后面具有以下优点：
第一，在电子设备开启音乐(又称响铃)提示和增强振动(又称振动)提示时，电子设备播放音乐类的提示信息时，可以同时根据音乐的特征驱动马达振动，使得马达输出和响铃对应的音乐有着同样的或者相似的节奏动感的增强振动效果，使得提示信息更加具有趣味性。
第二，在电子设备关闭音乐(又称响铃)提示且仅开启增强振动(又称振动)提示时，马达会根据增强随振信息来振动，可以增强振动强度，或者延长原始的短振时间或者缩短振动间隔。
这样可以进一步保证用户可以从触觉获知较为强烈的振动提示信息，不会错过来电、闹钟、短信以及备忘事件等等。解决了，由于音乐旋律、节拍或节奏的不稳定，导致振动时强时弱，时而一段时间内不振动，使得用户感受不到振动提示信息，进而错过重要电话、信息、通知、闹钟或者备忘事件等等。
接下来，先介绍申请提供的增强振动提示所应用的电子设备，包括电子设备的形态、软硬件架构等等。
电子设备可以是手机、相机、智能手表、运动手环、平板电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本，以及蜂窝电话、个人数字助理(personal digital assistant，PDA)、增强现实(augmented reality，AR)设备、虚拟现实(virtual reality，VR)设备、人工智能(artificial intelligence,AI)设备、可穿戴式设备、车载设备、智能家居设备和/或智慧城市设备等等。本申请实施例对此不作限制。

其中，控制器可以是电子设备100的神经中枢和指挥中心。控制器可以根据指令操作码和时序信号，产生操作控制信号，完成取指令和执行指令的控制。
处理器110中还可以设置存储器，用于存储指令和数据。在一些实施例中，处理器110中的存储器为高速缓冲存储器。该存储器可以保存处理器110刚用过或循环使用的指令或数据。如果处理器110需要再次使用该指令或数据，可从所述存储器中直接调用。避免了重复存取，减少了处理器110的等待时间，因而提高了系统的效率。
在本申请实施例中，处理器110检测到有提示信息输出时，例如来电、闹钟、短信、备忘事件提醒时，可以从存储器中获取对应的音乐文件，从该音乐文件中提取对应的增强随振信息，然后根据该增强随振信息控制马达振动。
其中，本申请对处理器110从音乐文件中提取对应的增强随振信息的方法不作限制。例如：
在本申请一些实施例中，处理器110可以直接从该音乐文件中获取音乐的特征，然后根据该音乐的特征计算得到标准随振信息，最后基于该标准随振信息再计算得到增强随振信息。这种情况下，直接获取的音乐的特征可以是预先经过人工从该首音乐中提取的综合特征信息。关于音乐的特征可以参考前文定义，在此暂不赘述。
在本申请另一些实施例中，处理器110可以采用算法从该音乐文件中计算得到音乐的特征，然后根据该音乐的特征计算得到标准随振信息，最后基于该标准随振信息再计算得到增强随振信息。这种情况下，经过计算获取的音乐的特征可以是音乐中的旋律、节奏或节拍中的任意一种。关于音乐的特征可以参考前文的定义，在此暂不赘述。
可理解的是，处理器110可以根据音乐的特征直接获取到增强随振信息，无需先计算标准随振信息，本申请对根据音乐的特征计算增强随振信息的具体实现过程不作限制。

在本申请实施例中，上述存储器中可以预先存储有各种提示信息对应的音乐文件、音乐的特征、标准随振信息以及增强随振信息等。
在处理器110直接从音乐文件中获取音乐的特征的情况下，存储器中存储的该音乐文件中包含，预先通过人工的方式获取的音乐的特征的相关信息。
马达191可以产生增强振动提示。马达191可以用于在电子设备检测到来电、信息、通知、闹钟、备忘事件、开启游戏或者播放视频等事件时进行增强振动提示，也可以用于触摸振动反馈。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反馈效果。作用于显示屏194不同区域的触摸操作，马达191也可对应不同的振动反馈效果。不同的应用场景(例如：时间提醒，接收信息，闹钟，游戏等)也可以对应不同的 振动反馈效果。触摸振动反馈效果还可以支持自定义。
在本申请实施例中，马达191的具体类型为线性马达。线性马达相比传统的转子马达来说，缩短了振动延迟时间以及避免了振动拖尾现象。可以为用户带来更好的振动体验。具体的，线性马达主要由定子和动子组成，动子主要是由特制质量块、弹簧、磁铁构成，定子则是由软性线路板(Flexible Printed Circuit board)FPC和环绕线圈构成。当线性马达接收到驱动信号后，线性马达中的定子线圈通电，由于磁场的存在，根据物理学家奥斯特发现的电流的磁效应，定子将受到磁场力的作用，会沿着特定的方向例如横向即左右方向带动动子运动，从而可以产生震感。可见，线性马达的工作原理则是类似于打桩机，线性马达主要是将电能转化为机械能，将电能直接转换为直线运动机械能，驱动弹簧质量块进行线性运动，从而产生振动，这种振动带给用户的震感类似于“哒哒哒”的效果。

其中，声音模式设置模块321显示有三个模式选项，包括：响铃选项321A、增强振动选项321B和静音选项321C。
上述三个选项对应的名称仅为示例，不应构成对本申请的限制，例如选项321B的名称即“增强振动”仅为示例，在本申请另一些实施例中，“增强振动”还可以被称为“振动”，本申请实施例对321B选项对应的名称不作显示，其对应的具体功能如下记载：
当用户选中响铃选项321A时，则电子设备100检测到有来电、信息、通知、闹钟、备忘事件、开启游戏或者播放视频等事件时，可以响铃来提示用户。具体的，电子设备100的音频模块170通过播放来电、信息、通知、闹钟、备忘事件、开启游戏或者播放视频等事件分别对应的音乐，以提示用户。
当用户选中增强振动选项321B时，则电子设备100可以通过输出增强振动效果来提示用户，具体的，电子设备100的马达可以根据上述来电、信息、通知、闹钟、备忘事件、开启游戏或者播放视频等事件时分别对应的音乐的特征进行振动，以提示用户。
当用户选中静音选项321C时，则电子设备100检测到有来电、信息、通知、闹钟、备忘事件、开启游戏或者播放视频等事件时，不输出音乐以及振动的提示信息。
其中，音量调节模块322分别显示有用于调节响铃时的音量控制条，即322A；和，用于调节那种对应的响铃时的音乐控制条，即322B。用户可以通过分别在上述两个控制条中左右滑动，以控制音量的高低。
其中，铃声设置模块323中，显示有来电铃声选项323A、信息铃声选项323B、通知铃声选项323C以及闹钟铃声选项323D。用户可以通过选择对应的选项，以选择来电、信息、通知、闹钟以及备忘事件对应的响铃音乐。这里的响铃音乐，可以是电子设备100出厂前预先存储在电子设备100中的音乐文件，也可以是用户自行下载的音乐文件，本申请实施例对此不作限制。
可以理解的是，图3B所示的内容仅为示例，在本申请另一些实施例中，图3B还可以报用于设置增强等级选项。该增强等级与马达振动强度、振动时间有关，具体的，当增强等级越高时，马达的振动强度可以越大，或者马达振动过程中每个子段之间的时间间隔越短，从而使得电子设备输出的振动效果越强烈。
可以理解的是，图3A-图3B仅仅示例性示出电子设备100开启增强振动功能的一种实施方式。在本申请另一些实施例中，用户还可以通过下拉通知栏，通过选择通知栏中提供的增强振动选项，使得电子设备100开启增强振动功能；或者，用户还可以通过输入语音 指令使得电子设备开启增强振动功能。本申请实施例对开启增强振动功能的方法不作限制。
假设用户，用户选择了图3B所示的增强振动321B对应的选项，并将来电铃声设置为音乐“Light”，将信息铃声设置为音乐“Shine”,将通知铃声设置为音乐“Light”，并且将闹钟铃声设置为音乐“Classic”时，则电子设备在检测到有来电、信息、通知、闹钟以及备忘事件等事件时，则会输出对应音乐的特征所对应的增强振动的效果。具体如下：
参考图3C，图3C示例性示出电子设备检测到来电时的场景示意图。
如图3C所示，电子设备100检测到来电时，电子设备100不仅会控制的显示屏194显示来电提示界面330，电子设备100还会控制马达输出来电音乐“Light”对应的增强振动效果。
可见，在电子设备100检测到来电时，即是电子设备100的响铃被关闭，或者用户的电子设备100被置于口袋亦或是被置于桌子上，或者用户处于嘈杂的环境中，使得用户听不到音乐“Light”。但是，用户仍然可以感受到，电子设备100控制马达输出来电音乐“Light”对应的增强振动效果，从而避免了漏接电话等类似事件的发生，提高用户体验感。
可以理解的是，图3C仅仅示例性示出，电子设备在检测到一个事件例如来电时，输出来电音乐对应的增强振动提示信息。在本申请另一些实施例中，当电子设备检测到两个冲突事件时，例如，电子设备在播放视频/打游戏的过程中输出视频中/游戏中音乐对应的增强振动提示信息时，又检测到来电、信息、通知、闹钟或者备忘事件时，则电子设备可以切换至输出来电、信息、通知、闹钟或者备忘事件的音乐多对应的增强振动信息，直至用户通过接听/挂断电话，查看信息、通知或备忘事件，或者关闭闹钟，以触发电子设备停止输出来电、信息、通知、闹钟或者备忘事件的音乐多对应的增强振动信息，或者直至电子设备自动停止输出来电、信息、通知、闹钟或者备忘事件的音乐多对应的增强振动信息后，电子设备才会继续输出视频中/游戏中音乐对应的增强振动提示信息。
可以理解的是，当用户选中响铃选项321A和增强振动选项321B时，则电子设备100检测到有来电、信息、通知、闹钟、备忘事件、开启游戏或者播放视频等事件时，电子设备不仅会输出对应的音乐以提示用户，还会根据音乐的特征输出对应的增强振动效果以提示用户。关于电子设备100根据音乐的特地点输出对应的增强振动效果的详细实现方法具体可以参考后文的方法流程的详细介绍，在此暂不赘述。
接下来结合图4来详细介绍本申请提供的增强振动提示方法。
图4示例性示出本申请提供的增强振动提示方法流程。该方法流程具体包括：
S401，电子设备基于特定事件对应的音乐获取该音乐的特征。
在一些实施例中，当电子设备100检测到有来电、信息、通知、闹钟以及备忘等事件时，电子设备100会获取来电、信息、通知、闹钟以及备忘等事件分别响铃时对应的音乐文件，然后从该音乐文件中获取音乐的特征。
在另一些实施例中，当电子设备100检测到用户设置来电、信息、通知、闹钟以及备忘等事件在响铃时的音乐后，电子设备可以根据设置好的音乐，获取上述事件分别对应的 音乐文件，并从该音乐文件中获取音乐的特征。
其中，来电、信息、通知、闹钟以及备忘等事件分别响铃时对应的音乐文件，可以是电子设备100默认设置的。也可以是用户重新选择的。关于用户设置上述事件在响铃时分别对应的音乐的方法，具体可以参考前文UI实施例中对图3B的介绍，在此暂不赘述。
一首音乐的特征包括：该首音乐中多个子段对应的音乐的起止时间，以及各个子段内音乐的音强和频率等信息。其中，一首音乐中的多个子段具体可以根据音乐的旋律、节奏和节拍中的一个或多个特征划分，具体如下：
其中，电子设备100根据音乐文件获取音乐的特征的具体实现方法如下：
方式1：音乐文件中预先存储有音乐的特征，电子设备100的处理器110从存储器获取音乐文件后可以直接提取该音乐的特征。其中，音乐文件中预先存储有音乐的特征，可以是通过人工方式获取音乐的特征。
通过人工的方式获取音乐的特征的具体实现如下：
参考图5，图5示例性示出一首音乐波形示意图。
如图5所示，该首音乐的波形示意图例如可以是上文所述的来电响铃对应的“Light”音乐。该音乐波形的横轴为播放音乐时的时间，纵轴为播放音乐时声音的强度即升压级。
开发人员可以在听该首音乐“Light”的同时提取“Light”音乐的特征，该“Light”音乐的特征包括：每个子段的起止时间，以及每个子段内音乐的音强和频率等信息。
例如，从该首音乐响起时，记录到子段1为从第2秒开始到第3秒结束，子段2为从第5秒开始到6第秒结束，子段3为从第8秒开始到第9秒结束，子段4为从第12秒开始到第14秒结束，子段5为从第16秒开始到第19秒结束，子段6为从第23秒开始到第25秒结束。
此外，开发人员还会记录，该音乐在每个子段中的音强和频率。例如子段1中的音乐的频率为50-200赫兹(Hz)，音强为40db，子段1中的音乐的频率为250-500Hz，音强为50db，子段3中的音乐的频率为大于500Hz，音强为60db等等这里不在一一赘述。
此外，上述用于提取音乐特征的开发人员可以是具备较强的乐感和乐理知识的专业音乐人士。
方式2：音乐文件中没有预先存储有音乐的特征，电子设备100的处理器110从存储器获取音乐文件后，处理器110可以调用视频编解码器将该音乐文件进行解压，然后数字信号处理器通过算法对解压后的音乐文件进行计算，可以提取该音乐的特征。其中提取音乐特征的算法具体包括：通过音乐节拍点来提取，通过频率来提取，通过不同响度来提取，通过频率与响度两者结合提取，以及通过AI/神经网络来提取处理等等。
本申请实施例仅以通过频率来提取音乐特征的算法进行介绍。具体实现如下：
参考图6，图6示例性示出提取音乐特征的算法框架示意图。
如图6所示，该算法框架包括高通、带通以及低通滤波器、频响门限，和标记特征起始点等模块。
首先，电子设备100中的视频编解码器将音乐文件解压后，获取到音乐流，通常一首音乐流中包含人声以及各种乐器声，所以解压后的音乐流是一个多音道的复杂音乐流。因 此，先通过高通、带通以及低通滤波器分别提取音乐流中的高频分量、中频分量和低频分量。然后将获取到的高频分量、中频分量和低频分量整合为一个简单音乐流。
之后，将简单音乐流分别输入频响门限1、频响门限2和频响门限3。其中，频响门限1用于将高频分量中的音乐信号频率大于第一预设频率的地方进行特征点的标记，从大于第一预设频率到小于第一预设频率的转折处再进行一次特征点标记，同时提取每一对从大于第一预设频率到小于第一预设频率的特征点之间的音乐流的频率和音强。同理，频响门限2用于将中频分量中的音乐信号频率大于第二预设频率的地方进行特征点的标记，从大于第二预设频率到小于第二预设频率的转折处再进行一次特征点标记，同时提取每一对从大于第二预设频率到小于第二预设频率的特征点之间的音乐流的频率和音强。同理，频响门限3用于将中频分量中的音乐信号频率大于第三预设频率的地方进行特征点的标记，从大于第三预设频率到小于第三预设频率的转折处再进行一次特征点标记，同时提取每一对从大于第三预设频率到小于第三预设频率的特征点之间的音乐流的频率和音强。
最后，将频响门限1、频响门限2和频响门限3分别输出的标记有特征起止点的音乐流合成为一个音乐流，该音乐流中携带有音乐特征，包括特征起止点(相当于子段起止点)，和每个子段的频率、音强等信息。
S402，电子设备基于音乐的特征获取增强随振信息。
具体的，在一种可实施的方式中，电子设备100根据音乐的特征获取对应的标准随振信息，然后基于标准随振信息获取增强随振信息。在另一种可实施的方式中，电子设备100可以直接根据音乐的特征获取对应的增强随振信息。
本申请实施例具体以通过人工的方式获取音乐特征的基础为例，接下来介绍上述第一种可实施方式，具体如下：
首先，电子设备100根据音乐的特征获取对应的标准随振信息，该标准随振信息包括每个子段中，马达振动起止时间、振动强度和振动频率。
参考图7，图7示例性示出根据标准随振信息生成的标准随振波形示意图。
如图7所示，该标准随振波形，包括多段振动，每段振动的起止时间对应上文图5所示的音乐波形中的特征点的起止时间。每段振动中，振动持续时间、振动强度以及振动频率可能相同可能不同。
其中，马达振动的持续时间即某段音乐播放中特征的持续时间。例如，第一段(子段1a)振动的持续时间和人工从音乐波形中提取的子段1的持续时间相同，第二段(子段2a)振动的持续时间和人工从音乐波形中提取的子段2的持续时间相同等等。
其中，振动的强度则与音乐强度一一对应。具体的，音强大于第一等级的音乐其对应的振动强度为第一振动强度，音强小于等于第一等级大于第二等级的音乐其对应的振动强度为第二振动强度，音强小于等于第二等级大于第三等级的音乐其对应的振动强度为第三振动强度，音强小于等于第三等级的音乐其对应的振动强度为第四振动强度。其中，第一等级的音强大于第二等级的音强，第二等级的音强大于第三等级的音强；第一振动强度大于第二振动强度，第二振动强度大于第三振动强度，第三振动强度大于第四振动强度。例如，音乐波形中子段1中的音强小于第三等级，则标准随振波形中子段1中的振动强度为 第四振动强度。又例如，音乐波形中子段3中的前一小节音强小于等于第二等级大于第三等级，则标准随振波形中子段3中的振动强度为第三振动强度。又例如，音乐波形中子段3中的后一小节音强小于等于第一等级大于第二等级，则标准随振波形中子段3中的振动强度为第二振动强度。可以理解的是，这里的音强等级划分和振动强度划分仅为示例，在其他一些实施例中，上述划分结果可以包括更多或者更少的等级，本申请实施例对此不作限制。
其中，振动频率与音乐的频率一一对应。具体的，当音乐的频率大于第一预设频率，则采用第一预设频率振动，当音乐的频率小于第一预设频率，则采用第二预设频率振动。可以理解的是，这里的音乐频率等级划分和振动频率划分仅为示例，在其他一些实施例中，上述划分结果可以包括更多或者更少的等级，本申请实施例对此不作限制。
之后，电子设备100基于标准随振信息获取增强随振信息。该增强随振信息包括每个子段中，马达振动起止时间、振动强度和振动频率。
在本申请实施例中，基于标准随振信息获取增强随振信息的方式可以是以下任意一种，或者结合以下任意多种，具体如下：
方式1：将标准随振信息中每个子段内的振动强度都增强以得到增强随振信息。参考图8，图8示例性示出采用方式1获取的增强随振信息所输出的增强随振波形1。
如图8所示，该增强振动波形1的强度大于等于标准随振波形中振动强度的最大值(即上文所述的第一振动强度)。并且，该增强振动波形1的每段振动的起止时间与标准随振波形一致、每段振动频率也与标准随振波形一致。也就是说，增强随振波形1中的子段1a与标准随振波形中的子段1的振动频率、振动起止时间一样，增强随振波形1中的子段2a与标准随振波形中的子段2的振动频率、振动起止时间一样等等。
方式2：将标准随振信息中每个子段内振动时间段小于第二值的振动时间延长，以得到增强随振信息。
参考图9，图9示例性示出延长子段振动时间的方法流程图。
如图9所示，电子设备可以根据图7所示的标准随振波形，判断标准随振波形中各个子段的振动时间是否小于或等于第一值，该第一值例如为1秒钟。当确定子段的振动时间小于(包含等于)1秒钟，则将该子段的振动时间延长一定值(例如0.5秒)；当确定子段的振动时间大于1秒钟时，则保持该子段的振动时间不变。此外，保持每个子段内段振动的强度与标准随振波形的振动强度保持一致、振动频率也保持一致。最后，整合各个子段以得到增强随振波形。
其中，延长子段的振动时间的方法包括：通过延长子段的振动终止时间，和/或，通过提前子段的振动起始时间，以延长振动持续时间。
方式3：将标准随振信息中相邻两个子段振动时间间隔大于第二值的间隔缩短，以得到增强随振信息。
参考图10，图10示例性示出缩短子段间隔的方法流程图。
如图10所示，电子设备可以根据图7所示的标准随振波形，判断标准随振波形中相邻两个子段之间的时间间隔是否大于或等于第二值，该第二值例如为3秒钟。当确定子段的振动时间大于(包含等于)3秒钟，则将该时间间隔缩短一定值(例如1秒)；当确定子段 的时间间隔小于3秒钟时，则保持该相邻子段的时间间隔不变。此外，保持每个子段内段振动的强度与标准随振波形的振动强度保持一致、振动频率也保持一致。最后，整合各个子段以得到增强随振波形。
其中，缩短相邻子段的时间间隔的方法包括：通过将前一个子段的终止时间延长或者后一个子段的起始时间提前，以缩短相邻子段的时间间隔。
参考图11，图11示例性示出同时采用方式2和方式3获取的增强随振信息所输出的增强随振波形2。
如图11所示，该增强振动波形2中的每个子段内段振动的强度与随振波形的振动强度保持一致、振动频率也保持一致。
并且，将随振波形中振动持续时间少于等于预设时间(例如1秒)的短振，统一增加振动时间。例如，图7所示的标准随振波形中子段1和子段2对应的两段振动分别持续时间都为1秒，为短振，因此，将子段1和子段2的时间分别延长一定值例如0.5秒也得到对应的子段1b和子段2b。
此外，还将随振波形中每个子段之间的时间间隔大于等于第二值(例如3秒)的前一个子段的终止时间延长或者后一个子段的起始时间提前。例如，图7所示的标准随振波形中子段3和子段4之间的时间间隔为3秒钟，因此，将子段3的终止时间延长，得到子段3b。例如，图7所示的标准随振波形中子段5和子段6之间的时间间隔为3秒钟，因此，将子段5的终止时间延长，得到子段5b。
上述方式1-3中任意多项可以结合使用。例如，既增强振动强度同时增加短振时间；或者既增强振动强度同时缩短振动间隔；或者既增加短振时间同时缩短振动间隔；或者既增强振动强度、也增加短振时间同时还缩短振动间隔。
S403，电子设备检测到特定事件。
该特定时间包括来电、信息、通知、闹钟或者备忘录等。
具体的，电子设备可以通过移动通信模块或者无线通信模块检测到蜂窝来电或者网络来电等事件。或者，电子设备可以通过移动通信模块检测到信息。或者，电子设备可以通过无线通信模块检测到通知。或者电子设备可以检测到闹钟或者备忘录等事件。
S404，电子设备响应于检测到的特定事件，基于对应的增强随振信息驱动马达振动。
具体的，电子设备100在获取当上述步骤S402所述的增强随振信息后，可以根据该增强随振信息中的每个子段的振动起止时间、振动强度和振动频率控制马达振动。从而使得马达振动带来的效果与响铃时播放音乐的效果有着共同节奏动感。
值得注意的是，在电子设备100基于增强随振信息驱动马达振动之前，电子设备需要预先开启增强振动功能。例如，可以在上述步骤S401-S403中任意步骤之前开启。
上述增强振动功能可以是电子设备100默认开启的，也可以是用户通过上文UI实施例中图3A-图3B所示的选择设置应用提供的增强振动选项321B，或者是用户通过，选择下拉通知栏中提供的增强振动选项，或者是通过语音指令等方式，以触发电子设备100开启 增强振动功能。
在采用本申请提供的增强振动提示方法后，可以实现以下效果：
效果1：在电子设备100检测到来电、信息、通知、闹钟以及备忘事件等时，若电子设备100预先开启音乐提示和振动提示，即开启响铃功能和增强振动功能的情况下，电子设备100会伴随着音乐的特点进行振动，同时带给用户听觉上的和触觉上的提示，增加了提示的趣味性。
效果2：如果电子设备配置的马达的体积/规格/性能一般，在没有响铃音乐播放的情况下，即用户仅开启增强振动提示时，若电子设备100被置于口袋、桌上、背包中时，尽管响铃音乐中有的时间段内乐感较弱，但或通过将振动强度提高，或者将短振的时间延长，或者将振动间隔压缩，从而实现增强了乐感较弱的部分所对应的振动效果。从而避免用户漏接电话，或者漏看信息、通知、闹钟或者备忘事件等，从而提高用户体验感。
