目前，手机、平板等终端设备普遍使用线性马达，特别是一些应用通过扩展的振动接口来实现线性马达的宽频振动，以便给用户提供丰富的振动触感，实现触觉交互。例如用户使用终端设备玩游戏时，终端设备可在用户释放技能时振动，给用户以触觉反馈。
为保证线性马达的稳定性及可靠性，厂商需要对线性马达进行老化测试。老化测试是指模拟产品在现实使用条件中涉及到的各种因素对产品产生老化的情况进行相应条件加强试验的过程。但传统的老化测试通常是控制线性马达连续振动或者间歇振动，无法完全覆盖线性马达的使用场景，导致测试并不全面，进而使得测试结果不够准确。

具体实施方式
以下结合附图对本申请的示范性实施例做出说明，其中包括本申请实施例的各种细节以助于理解，应当将它们认为仅仅是示范性的。因此，本领域普通技术人员应当认识到，可以对这里描述的实施例做出各种改变和修改，而不会背离本申请的范围和精神。同样，为了清楚和简明，以下的描述中省略了对公知功能和结构的描述。
为了下述各实施例的描述清楚简洁，首先给出相关技术的简要介绍。
非线性马达，又称为转子马达。转子马达可包括铁芯马达和扁平马达，它们是通过加电后轴的旋转带动轴上的偏心质量块(也可称为转子)旋转而产生振动。
线性马达，是通过脉冲电压信号产生变化的电磁场，由变化的电磁场来驱动磁钢带动质量块进行周期运动的机构。其中，脉冲电压信号的频率、幅度不同，则线性马达的振动强度不同。
在通过线性马达模仿真实世界的触感时，主要影响其用户体验的有四个方面的参数，分别为包括：谐振频率(F0)、振动频宽、振动量以及响应时间。
谐振频率(F0)，也可称为固有频率，指能够使线性马达发生共振的频点。如图1所示，设备可以较低的驱动电压使线性马达在谐振频率(F0)附近进行受迫振动，并达到很大的振动幅度。
振动频宽，可指马达的振动频率的范围。振动频宽直接决定了触觉反馈输出给用户的体验的丰富度和层次感，也决定了内容和系统设备商提升用户体验的空间大小。其中，振动频宽越大，则线性马达支持的振动方式越丰富，对交互场景的覆盖越广。
振动量，也可以称为振幅，或者振动强度。在其他参数等价的前提下，振动量越大，振感越强，其与谐振频率共同决定着用户对触感强弱的主观感知。
响应时间，指终端设备接收到振动事件，到马达开始振动所需的时间。响应时间 直接决定了用户在触觉交互体验之时的延迟和拖尾，例如游戏玩家通常所说的枪械振感是否灵敏、清脆，就是受响应快慢的影响。
现有技术中，厂商对线性马达采用传统的老化测试方法。传统的老化测试方法其主要是控制马达进行连续振动或间歇振动，以测试马达的寿命。但这种老化测试方法更适配于非线性马达的使用场景，无法完全覆盖线性马达的使用场景，特别是线性马达需要宽频振动的场景，导致对线性马达的测试并不全面，进而使得测试结果不够准确。
本申请提供一种线性马达的老化测试方法，应用于包括线性马达的终端设备。该方法可以基于多种驱动方式对应的振动参数生成测试参数，并按照该测试参数对应的驱动方式控制振动芯片向线性马达输出电压，以使线性马达按照该测试参数指示的方式振动。由于多种驱动方式可驱动线性马达进行连续振动、间歇振动或者宽频振动，可测试线性马达在不同场景下的振动情况，也就是说本申请覆盖的测试场景更广，从而得到的测试结果更符合实际，也更加精准。
需要说明的是，本实施例所述的终端设备，可以为手机、平板电脑、个人通信业务(personal communication service，PCS)电话、可穿戴设备、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等，在此不作具体限制。

下面结合附图说明本申请提供的线性马达的老化测试方法。
终端设备可接收用于触发测试事件的第一操作，响应于该第一操作，终端设备对线性马达进行老化测试。在本实施例中，终端设备可安装有用于对线性马达进行老化测试的第一应用。可选的，该第一应用可以是对用户可见的应用。示例性的，如图5中的(a)图所示，终端设备(例如手机)可显示界面501。该界面501也可以称为主界面或者home界面等。界面501可包括测试应用(即第一应用)的图标501a。终端设备可以接收用户对图标501a的操作，响应于该操作，如图5中的(b)所示，终端设备显示测试应用的界面502。该界面502包括一个或多个测试项目，一个或多个测试项目可包括线性马达老化测试502a、线性马达振动量测试、线性马达瞬态响应测试等。需要说明的是，该一个或多个测试项目还可以包括恢复测试、安全测试、压力测试等测试项目，或者仅包括线性马达老化测试这一个测试项目。换句话说，该第一应用可以为仅用于进行线性马达老化测试的应用，也可以为可进行多项测试的应用，在此不做具体限制。若用户终端设备希望进行线性马达的老化测试，可点击该线性马达老化测试502a。终端设备可接收到用户对线性马达老化测试502a的操作，作为响应，如图5中的(c)所示，终端设备可显示界面503。该界面503可包括开始测试的控件503a。终端设备可以接收用户对该开始测试的控件503a的操作，响应于该操作，终端设备对线性马达进行老化测试，在测试过程中终端设备可以不同的方式振动。可以理解地，在上述场景中，用户对该开始测试的控件503a的操作即为一种用于触发测试事件的第一操作。
需要说明的是，图5所示的场景仅为示意。在其他实施方式中，该第一应用可以是对用户不可见的应用，即界面501中可以不包括测试应用的图标501a。在这种情况下，用户可以通过拨号界面输入预设字符(例如*#12345#)。终端设备可以接收到用户输入预设字符的操作，响应于该操作，终端设备可显示界面502，以使用户按照图5中的(b)和图5中的(c)所示的流程发起第一操作，以使终端设备进行线性马达的老化测试。
在另一种可选的实施方式中，响应于接收到用户输入预设字符的操作，终端设备可直接运行第一应用以对线性马达进行老化测试，无需用户再在界面上进行相关操作。在这种场景下，用户输入预设字符的操作即为一种用于触发测试事件的第一操作。
在一种可选的实施方式中，响应于接收到第一操作，终端设备生成测试参数，以及基于该测试参数控制振动芯片向线性马达输出驱动电压，以使线性马达按照该测试参数指示的方式进行振动。
测试参数为在测试过程中终端设备所使用的振动参数。该振动参数可用于指示线性马达的振动方式。在本实施例中，针对不同的驱动方式，终端设备可采用不同的振动参数。在本实施例中，基于控制线性马达振动过程中所使用的振动接口不同，驱动方式可包括三种，分别为：使用通用振动接口实现振动的驱动方式、使用自研振动接口实现振动的驱动方式，以及使用4D振动接口实现振动的驱动方式。不同驱动方式的实现逻辑并不相同，后文将详细描述如何使用不同的驱动方式实现振动，详情参见图6-图12及相关描述，在此暂不描述。
在本实施例中，通用振动接口也可以称为谷歌振动接口或者标准接口，可用于实现连续振动或者间歇性振动。对于使用通用振动接口实现振动的驱动方式，其所采用的振动参数可包括线性马达进行连续振动或者间歇性振动所需的振动时长、休眠时长和等待时长等。该振动时长指在一次振动过程中线性马达处于振动状态的时长，休眠时长指在一次振动过程中线性马达处于静态状态的时长，等待时长指两次振动过程之间所间隔的时长。
自研振动接口也可以称为原生振动接口，通常是设备厂商自己研发的振动接口，可用于实现设备厂商自定义的振动方式。对于使用自研振动接口实现振动的驱动方式，其所采用的振动参数可包括波形名称和等待时长。在本实施例中，终端设备中存储有波形描述信息，该波形描述信息包括多个振动波形的名称及对应的波形数据，其中每个波形数据用于指示对应的振动波形。如此，根据波形名称便可确定线性马达的振动方式。在一种可选的实施方式中，该波形描述信息可以可扩展标记语言(extensible markup language，XML)文件的格式进行记录。
4D振动接口可以是多个第三方应用厂商联合开发的振动接口，可用于实现第三方应用厂商自定义的振动方式。对于使用4D振动接口实现振动的驱动方式，其所采用的振动参数可包括波形文件标识和等待时长。该波形文件标识用于供终端设备快速查找到波形描述文件，以确定线性马达的振动方式。
在本实施例中，终端设备中还存储有多个波形描述文件，一个波形描述文件用于描述一个振动波形，例如该振动波形的振动强度(intensity)、振动频率(frequency)、振动类型(type)和相对时间(relative time)等。其中，振动类型可包括连续振动、瞬态振动或者宽频振动。
考虑到该多个波形描述文件是由多个第三方提供的，多个波形描述文件可能存在重名的情况，终端设备可将不同第三方提供的波形描述文件存储在不同的路径下，这样可以通过存储路径以及文件名称区分波形描述文件。在这种情况下，波形文件标识包括存储路径和文件名称。可选的，终端设备还可以给不同的波形描述文件分配不同的文件ID，以便通过文件ID来区分波形描述文件。在这种情况下，波形文件标识包括文件ID。
需要说明的是，上述波形文件标识还可以为其他，在此不做具体限制。另外，上述振动接口的名称和振动接口可实现的振动方式仅为示例，振动接口的名称也可以为 其他，所实现的振动方式也可以更丰富，在此不做具体限制。
在一种可选的实施方式中，终端设备生成测试参数进一步包括：终端设备基于配置信息生成测试参数，该测试参数与多种驱动方式中的目标驱动方式对应。
其中，目标驱动方式为使用通用振动接口实现振动的驱动方式、使用自研振动接口实现振动的驱动方式以及使用4D振动接口实现振动的驱动方式这三种驱动方式中的任意一种。
可选的，终端设备可按照预设顺序将上述三种驱动方式依次作为目标驱动方式。示例性的，终端设备可将使用通用振动接口实现振动的驱动方式、使用自研振动接口实现振动的驱动方式，以及使用4D振动接口实现振动的驱动方式依次作为目标驱动方式。
可选的，终端设备可随机将三种驱动方式中的任意一种驱动方式作为目标驱动方式。在一种可选的实施方式中，三种驱动方式具有相同的权重，这种情况下每种驱动方式被选中成为目标驱动方式的概率相同。在一种可选的实施方式中，三种驱动方式具有不同的权重，例如可以将其中一个或两种驱动方式的权重设置得较大，以使该驱动方式被选中成为目标驱动方式的概率更大。
其中，终端设备上存储有配置信息。该配置信息包括多种驱动方式对应的振动参数。具体的，配置信息可包括不同驱动方式所需的振动参数的所有可能取值(也可称为取值范围)。
示例性的，配置信息可包括使用通用振动接口实现振动的驱动方式所需的振动参数的所有可能取值(如表1所示)。
表1
其中，根据表1可知，对于使用通用振动接口实现振动的驱动方式，其所需的振动参数包括振动时长、休眠时长和等待时长。其中，振动时长可以为0～2500ms中的任意一个数值；该休眠时长可以为0～5000ms中的任意一个数值；该等待时长可以为10～2000ms中的任意一个数值。需要说明的是，该表1仅为示例，各个参数的取值可以根据需要进行设置。
另外需要说明的是，该振动时长、休眠时长以及等待时长的各个取值之间不存在关联关系，即振动时长为0时，休眠时长可以为0～5000ms中的任意值，等待时长也可以为10～2000ms中的任意值。
可选的，表1所示的配置信息可以XML文件的格式进行记录。示例性的，该XML文件可包括：

其中，“NAME”用于标识振动的类型，例如“XXXX_Native”用于指示使用通用振动接口实现振动的驱动方式；“<UNIT>ms</UNIT>”用于指示取值单位为ms(毫秒)，“ON”用于列举振动时长的所有可能取值，例如“<value>1</value>”表明振动时长可以为1ms；“SLEEP”用于列举休眠时长的所有可能取值，例如“<value>20000</value>”表明休眠时长可以为20000ms；“WAIT”用于列举等待时长的所有可能取值，例如“<value>20</value>”表明等待时长可以为20ms。需要说明的是，上述XML文件仅为示例，XML文件还可包括比上述列举的更多的内容，且“ON”、“SLEEP”以及“WAIT”的取值也可以更多。
在本实施例中，配置信息还可包括使用自研振动接口实现振动的驱动方式所需的振动参数的所有可能取值(如表2所示)。

需要说明的是，若一个振动波形包括多个基础振动波形，则多个基础振动波形之间的时间间隔可以为预设的第一数值，或者为测试参数中携带的等待时长，在此不做具体限制。
S610，自研振动接口向振动驱动发送第一波形数据和等待时长。
S611，振动驱动基于第一波形数据得到配置参数。
其中，该配置参数包括第一波形数据对应的振动波形在多个时刻的振动量，用于描述线性马达在振动期间振动量随时间的变化情况。在本实施例中，配置参数以脉冲编码调制(pulse code modulation，PCM)的编码格式存在。
可选的，终端设备预存储有各个基础振动波形的序号和基础振动波形的PCM编码的对应关系，振动驱动可基于第一波形数据所携带的基础振动波形的序号查找对应的PCM编码，再结合第一波形数据携带的振动时长进行调整，即可得到配置参数。
S612，振动驱动将配置参数写入振动芯片。
S613，振动芯片向线性马达输出驱动电压，以使线性马达按照测试参数指示的方式振动。
示例性的，自研振动接口接收到的振动参数包括波形名称(例如为notice1)以及 等待时长(例如为135ms)。如此，自研振动接口可根据notice1在表4中查询得到波形数据<10,02,200,04>。结合图9所示的对应关系可知，该波形数据对应的振动波形可如图10所示。其中线性马达以02号基础振动波形振动10ms，等待135ms以后，再以04号基础振动波形振动200ms。另外，在线下马达以04号基础振动波形振动200ms结束时开始，经过135ms后线性马达可进行下一次振动，下一次振动的振动方式可与此次振动的振动方式不同。
下面以测试参数对应使用4D振动接口实现振动的驱动方式为例进行说明，图11为本申请提供的一种线性马达的老化测试方法的流程示意图三。如图11所示，在S603之后，还包括：S614～S619。

S617，振动驱动基于第一波形数据得到配置参数。
其中，振动驱动可根据第一波形数据确定振动波形。示例性的，该振动强度可以为75，振动频率为50Hz，振动类型为瞬态振动，相对时间为0，则得到的振动波形可以如图12所示。振动驱动确定振动波形后，可将该振动波形转换为PCM编码的格式，以得到配置参数。
S618，振动驱动将配置参数写入振动芯片。
S619，振动芯片向线性马达输出驱动电压，以使线性马达按照测试参数指示的方式进行振动。
如此，线性马达可按照图12所示的波形进行振动。
需要说明的是，图6、图8及图11仅示出了终端设备控制线性马达进行一次振动的流程。在实际测试过程中，终端设备控制线性马达振动一次后，可重新生成测试参数，再基于重新生成的测试参数控制线性马达振动，以测试线性马达的寿命。
在一种可选的实施方式中，若时间间隔大于等于第一等待时长，终端设备可基于多种驱动方式对应的振动参数重新生成测试参数。其中，时间间隔为当前时刻与线性马达最近一次振动的终止时刻之间的差值，第一等待时长为驱动线性马达进行最近一次振动的测试参数中携带的参数。例如，线性马达在12:00结束了第一次振动，其中用于驱动线性马达进行第一次振动的测试参数中携带的等待时长为200ms，则终端设备可在12:00后的第200ms时重新生成测试参数，以基于重新生成的测试参数控制线性马达再次振动，多次重复此流程后，可以测试线性马达在各个应用场景下的振动情况，并确定线性马达的老化情况。
在另一种可选的实施方式中，终端设备可以一次性生成多组测试参数，或者在任意时刻生成新的测试参数，在时间间隔大于第一等待时长时，再基于新的测试参数对应的驱动方式控制振动芯片向线性马达输出电压。也即，可以不限制生成测试参数的时间，只要使得两次振动的时间间隔不小于测试参数中携带的等待时长即可。
综上所述，本申请提供的线性马达的老化测试方法，可测试线性马达在不同场景下的振动情况，覆盖的测试场景更广，从而得到的测试结果更符合实际，也更加精准。
