具体实施方式
为了能够更加详尽地了解本发明实施例的特点和技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
在以下的描述中，涉及到“一些实施例”，其描述了所有可能实施例的子集，但是可以理解,“一些实施例”可以是所有可能实施例的相同子集或不同子集，并且可以在不冲突的情况下相互结合。
在以下的描述中，所涉及的术语“第一\第二\第三”仅仅是是区别类似的对象，不代表针对对象的特定排序，可以理解地，“第一\第二\第三”在允许的情况下可以互换特定的顺序或先后次序，以使这里描述的本发明实施例能够以除了在这里图示或描述的以 外的顺序实施。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中所使用的术语只是为了描述本发明实施例的目的，不是旨在限制本发明。
相关技术中，随着终端设备的长时间使用，终端设备所处的温度原因，马达等谐振装置的固有频率有可能发生偏移，出厂前校准过的实际采样频率也有可能会偏移，导致谐振装置成品实际的谐振频率与谐振频率设计值存在一定的偏差，使得谐振装置的振动量发生变。而谐振装置的采样频率的校准需要依靠精密设备，以重新配置谐振装置的波形数据，以使校准后的采样频率适配偏移后的固有频率，因此，相关技术中谐振装置的采样频率不适合消费电子设备出厂后的自校准。
基于上述问题，本发明实施例提供一种振动控制方法，应用于具有谐振装置的终端设备。终端设备可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
谐振装置指马达等能够基于固有频率和采样频率的适配产生振动的组件。其中，马达可为线性谐振马达(Linear Resonance Actuator，LRA)。谐振装置的振动能够被人们感知从而产生触觉反馈效果。
线性谐振马达包括：弹簧、带有磁性的质量块和线圈。弹簧将线圈悬浮在线性谐振马达内部，当线圈中有电流流过时，线圈会产生磁场。线圈和带有磁性的质量块相连，当流过线圈的电流改变时，磁场的方向和强弱也会改变，质量块就会在变化的磁场中上下移动。线性谐振马达基于质量块的移动而运动，这种运动被人们感知从而产生触觉反馈效果。
本发明实施例中，终端设备利用存储多种驱动波形数据的驱动芯片来根据不同的场景去实现不同的振动波形，实现不一样的振动效果，从而提升不同场景下的振动体验。
本发明实施例提供的振动控制方法，如图1所示，包括：
S101，采集终端设备的温度。
本发明实施例提供的终端设备中可设置有温度传感器，温度传感器能够感应终端设备的温度。可选地，温度传感器为终端中系统的温度传感器。可选地，温度传感器为基于振动控制在终端设备中增设的温度传感器。
以温度传感器为基于振动控制在终端设备中增设的温度传感器为例，温度传感器在终端设备中设置的位置为靠近终端设备中主板的位置，以精确地确定终端设备的温度。
在一示例中，温度传感器设置在主板上靠近谐振装置的周围，以采集终端设备中主板上靠近谐振装置的区域的温度。
在一示例中，温度传感器为设置在主板上温度敏感的区域，以能够快速地感应终端设备的主板的温度的变化。其中，主板上温度敏感的区域相对于主板上的其它区域，能够快速地对温度做出反应。比如：当终端设备运行的应用程序的所消耗的内存大于指定内存时，终端设备的处理器高功率运行，使得主板发热，温度敏感的区域相对其他的区域的温度明显升高，且当运行的应用程序的所消耗的内存减小或终端处于休眠状态，温度敏感的区域相对其他的区域的温度明显下降。又比如：当终端设备处于快速充电状态使得主板发热，温度敏感的区域相对其他的区域的温度明显升高，当终端设备结束充电，温度敏感的区域相对其他的区域的温度明显下降。
本发明实施例中，对温度传感器的数量和温度传感器的设置位置不进行任何限定。
在一示例中，当终端设备中设置多个温度传感器，可将多个温度传感器所采集的温度中的最高温度作为终端设备的温度。
在一示例中，当终端设备中设置多个温度传感器，可将多个温度传感器所采集的温度的平均温度作为终端设备的温度。
终端设备通过温度传感器采集的温度为终端设备的实时温度，比如：0摄氏度(℃)、5℃、10℃。
可选地，终端设备基于接收到的指示所述谐振装置进行振动的驱动指令的触发，生成温度检测指令；基于所述温度检测指令开始采集所述终端设备的温度。
终端设备可基于用户操作、来电、系统提醒等事件接收到驱动指令，以指示谐振装置进行振动，终端设备基于接收到的驱动指令的触发生成指示温度传感器采集温度的温度检测指令，并基于温度检测指令控制温度传感器开始采集设备的温度，以通过温度传感器采集终端设备的温度。
S102，确定所述温度对应的目标频率偏移量。
终端设备基于S101确定的温度确定对终端设备的采样频率进行校正的目标频率偏移量。
本发明实施例中，确定温度对应的目标频率偏移量的方式包括以下之一：
方式一、获取设定的温度范围与频率偏移量的对应关系所包括的的温度范围；确定所获取的温度范围中，所述温度所属的目标温度范围；根据所述对应关系，确定所述目标温度范围对应的目标频率偏移量；
方式二、将所述温度输入偏移量网络模型，得到所述偏移量网络模型输出的目标频率偏移量。
在方式一中，终端设备设置有频率偏移量列表。频率偏移量列表中包括有设定的温度范围和频率偏移量的对应关系，其中，不同的对应关系中，温度范围不同，且不同的温度范围对应的频率偏移量不同。终端设备获取对应关系所包括的温度范围，并确定采集的温度所属的温度范围即目标温度范围，将频率偏移量列表中该目标温度范围对应的频率偏移量作为所采集的温度对应的目标温度偏移量。
在一示例中，频率偏移量列表如表1所示，设定的对应关系中包括的温度范围包括：-20至25℃、25至30℃以及30至80℃，当采集的终端设备的温度为-10℃，-20至25℃、25至30℃以及30至80℃中，-10℃所属的目标温度范围为-20至25℃，则对应的目标频率偏移量为-2赫兹(HZ)；当采集的终端设备的温度为20℃，所属的目标温度范围为25至30℃，则对应的目标频率偏移量为0HZ。
表1 频率偏移量列表示例
温度范围，单位：摄氏度 频率偏移量，单位：HZ
-20-25 -2
25-30 0
30-80 +5
其中，在表1中，频率偏移量为-2，表征将谐振装置的采样频率减小2HZ，+5表征将谐振装置的采样频率增大5HZ。
本发明实施例中，频率偏移量存在正数、零、负数三类。当频率偏移量为正数时，表征增大谐振装置的采样频率；当频率偏移量为零时，表征谐振装置的采样频率不变；当频率偏移量为负数时，表征减小谐振装置的采样频率。
本发明实施例提供的振动校正方法可应用于不同的场景，比如：游戏场景、来电场 景、闹钟提醒场景等。针对不同的场景，驱动谐振装置振动的驱动信号的波形不同。可选地，终端设备针对不同场景采用同一频率偏移量列表。
本发明实施例中，终端设备中的偏移量列表中的温度范围与频率偏移量的关系可根据实际需求进行设置。
在方式二中，终端设备中设置有基于温度样本和对应的频率偏移量样本训练的偏移量网络模型。终端设备将采集到的温度输入至偏移量网络模型，偏移量网络模型的输出为输入的温度对应的目标频率偏移量。
本发明实施例中，温度样本和对应的频率偏移量样本可为终端设备从网络获取的样本数据，也可为终端设备接收的用户输入的样本数据。可选地，，温度样本和对应的频率偏移量样本还可包括终端设备中控制谐振装置的振动的历史温度以及对应的历史频率偏移量。本发明实施例对训练偏移量网络模型的样本数据的获取途径不进行任何的限定。
本发明实施例中，终端设备的偏移量网络模型所采用的算法为神经网络算法，对偏移量网络模型的结构不进行任何的限定。
可选地，终端设备确定温度对应的目标频率偏移量的方式包括：将采集的温度发送至网络侧，并接收网络侧返回的发送的温度对应的目标频率偏移量。对于网络侧根据接收的温度确定需返回的目标频率偏移量的确定方式不进行任何的限定。
S103，根据所述目标频率偏移量控制所述终端设备中的谐振装置的振动。
终端设备确定目标频率偏移量后，通过目标频率偏移量对驱动谐振装置振动的驱动信号的采样频率进行调整，以对谐振装置的采样频率进行调整，与谐振装置的固有频率趋于一致，控制所述终端设备中的谐振装置的振动得到校正。
可选地，如图2所示，S103包括：
S1031，获取驱动所述谐振装置进行振动的驱动信号的参考频率。
这里，参考频率为终端设备设置的驱动谐振装置振动的驱动信号的采样频率。可选地，不同的场景下驱动信号的参考频率相同。
S1032，根据所述目标频率偏移量对所述参考频率进行校正，得到目标频率。
终端设备获取参考频率后，将目标频率偏移量与参考频率相加，得到根据目标频率偏移量对参考频率进行校正之后的目标频率。
在一示例中，参考频率为F ref，目标频率偏移量为ΔF，目标频率为F通过公式(1)计算得到：
F＝F ref+ΔF       公式(1)。
在一示例中，谐振装置的振动时间为t1至t2，其中，驱动信号在基于目标频率进行校正之前的波形如图3所示，在t1至t2这段时间内的采样频率为参考频率，参考频率的大小为f1，当电子设备的温度为40℃时，驱动信号在基于目标频率进行校正之后的波形如图4所示，在t1至t2这段时间内的采样频率为目标频率，目标频率的大小为f2，其中，且f1<f2。
S1033，以所述目标频率驱动所述谐振装置进行振动。
终端设备以采样频率为目标频率的驱动信号驱动谐振装置进行振动，使得采样频率适配谐振装置的固有频率，从而对终端设备的振动进行校正。
本发明实施例中，对驱动信号的采样频率进行调整时，对驱动信号的波形不进行调整，因此，基于目标频率偏移量控制所述终端设备中的谐振装置的振动后，谐振装置在不同的场景下能够继续进行不同的振动，从而满足多场景的需求，使得用户针对当前的振动情况区分不同的场景。
本发明实施例中，在S103之后，如图5所示，还包括：
S104，检测所述谐振装置振动的频率。
这里，检测谐振装置基于目标频率偏移量对驱动信号的采样频率校正的得到采样频率驱动时振动的频率，从而监测当前目标频率偏移量的校正效果。
可选地，当终端设备的温度属于当前目标频率偏移量对应的温度范围时，检测谐振装置振动的频率。
S105，根据所检测的频率，对所述目标频率偏移量进行校正，得到校正后的目标频率偏移量。
终端设备根据检测的当前目标频率偏移量的校正效果对目标频率偏移量进行校正。可选地，当校正效果达到预期的校正效果，则对当前目标频率偏移量不进行校正。可选地，当校正效果未达到预期的校正效果，则对当前目标频率偏移量进行校正。
当终端设备对目标频率偏移量进行校正，得到校正后的目标频率偏移量，则使用校正后的目标频率偏移量控制谐振装置的振动。
可选地，以驱动所述谐振装置振动的驱动信号的参考频率作为校正效果的衡量参数。此时，S105包括：将所检测的频率和驱动所述谐振装置振动的驱动信号的参考频率进行比较；当所检测的频率和所述参考频率的频率差值大于指定的频率差阈值，通过所述频率差值对所述目标频率偏移量进行校正，得到校正后的目标频率偏移量。
当所检测的频率和所述参考频率的频率差值大于指定的频率差阈值，表征校正效果未达到预期的校正效果，需要对目标频率偏移量进行校正。当所检测的频率和所述参考频率的频率差值不大于指定的频率差阈值，表征校正效果达到预期的校正效果，不需要对目标频率偏移量进行校正。
对目标频率偏移量进行校正的方式包括：通过检测的频率和参考频率的频率差值对所述目标频率偏移量进行校正，得到校正后的目标频率偏移量。这里，校正后的目标频率偏移量ΔF 校可通过公式(2)计算得到：
ΔF 校＝F 差+ΔF         公式(2)；
其中，F 差为检测的频率和参考频率的频率差值。
本发明实施例中，在得到校正后的目标频率偏移量，对目标频率偏移量或偏移量网络模型进行更新。
可选地，在终端设备确定温度对应的目标频率偏移量的方式为方式一的情况下，基于所述校正后的目标频率偏移量，对温度范围与频率偏移量的对应关系中的所述目标频率偏移量进行更新。
这里，对频率偏移量列表中的目标频率偏移量进行更新，更新为校正后的目标频率偏移量。
在一示例中，频率偏移量列表的对应关系如表1所示，当温度为40℃时，目标频率偏移量为5HZ，对目标频率偏移量校正后得到的校正后的目标频率偏移量为6HZ，则更新后的频率偏移列表如表2所示。
表2 更新后的频率偏移量列表示例
温度范围，单位：摄氏度 频率偏移量，单位：HZ
-20-25 -2
25-30 0
30-80 +6
可选地，在终端设备确定温度对应的目标频率偏移量的方式为方式二的情况下，基于所述校正后的目标频率偏移量，对偏移量网络模型的参数进行更新。
终端设备基于当前温度和校正后的目标频率偏移量对偏移量网络模型的参数进行更新，使得偏移量网络模型的输出，使得偏移量网络模型针对输入的温度所输出的频率 偏移量适应终端设备的使用情况，保持驱动信号的采样频率适配谐振装置的固有频率。
本发明实施例中，通过校正后的目标频率偏移量对对应关系中的目标频率偏移量或偏移量网络模型的参数进行更新，从而通过校正效果对确定目标频率偏移量的温度范围和频率偏移量的对应关系，或偏移量网络模型进行反馈调节，以精确地确定消除谐振装置因为温度所带来的振动偏差的频率偏移量，使得终端设备中存储的频率偏移量列表、以及偏移量网络模型能够随着终端设备中谐振装置的固有频率的偏差的调整而动态调整。
下面，以确定温度对应的目标频率偏移量为方式一，且马达为为例，对本发明实施例提供的振动控制方法进行举例说明，如图6所示，包括：

终端设备定时获取系统温度。当前终端设备的温度可以由终端设备内增加的温度传感器去获取，也可以通过系统自带的温度传感器去获取。
S603，判断关系表中是否有对应当前系统的温度的频率偏移量。
终端设备的上层软件服务查询预设的关系表，以判断在预设的关系中是否存在当前系统的温度是所对应的频率偏移量。若没有，则执行S604，若有，则执行S605。
S604，通过驱动芯片使用默认的频率输出驱动信号。

本发明实施例中，终端设备的系统包括：上层服务和底层系统两个层级；上层服务则负责逻辑的判断，而底层系统则负责设置驱动芯片。
本发明实施例中，终端设备的硬件组成包括：终端系统、驱动芯片和谐振装置(比如：马达)。其中，终端系统和驱动芯片可通过中断引脚、串行外设接口(Serial Peripheral Interface,SPI)或者两线式串行总线(Inter－Integrated Circuit，I2C)接口进行数据交互通信。
