具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，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。
图1为本申请一个实施例提供的游戏手柄示意图。
参照图1，游戏手柄100为常见电子游戏机的部件，通过操纵其按键等，实现对游戏虚拟角色的控制。常见的游戏手柄100可以包括：十字键101(方向)、ABXY键102(动作-亦有硬件生产商使用不同方法标记，但排列方式大体相同)、摇杆103(方向及视角)、扳机键104以及HOME菜单键105等按键，本实施例提供的力反馈装置的降噪方法，对游戏手柄的按键的类型、个数、排列方式等均不做限定。
玩家在玩游戏时，将游戏手柄连100接至终端(如计算机、电视机或智能终端等)，终端屏幕上呈现游戏的当前场景信息，玩家操控游戏手柄上的按键，控制游戏画面的显示及游戏中的虚拟角色。
在游戏中的相应场景含有振动事件时，需要游戏手柄100进行相应振动以为玩家提供振感。其中，游戏手柄100可以包括具有振动功能的相应器件。在一种实施方式中，该游戏手柄100还可以内置力反馈装置，用于在游戏中的出现振动事件时进行振动以为玩家提供相应振感。
在一种实施方式中，一个游戏手柄中可以包括一个或多个力反馈装置。当游戏中出现振动事件时，游戏手柄可以通过该一个或多个力反馈装置进行振动，玩家可以通过振感获知游戏反馈信息。
在游戏手柄中设置一个力反馈装置的场景中，在游戏中出现振动事件时，游戏手柄控制该一个力反馈装置进行振动，玩家可以通过振感获知游戏反馈信息。
在游戏手柄中设置至少两个力反馈装置的场景中，游戏手柄通过该至少两个力反馈装置中相对应的力反馈装置进行振动，从而玩家可以通过振感获知游戏反馈信息。
以设置两个力反馈装置为例，该两个力反馈装置可以分别设置在游戏手柄的两侧。游戏手柄可以在获取到显示游戏画面的屏幕的坐标系信息后，在游戏过程中获取游戏中振动事件相对于屏幕的坐标信息，进而确定需要触发力反馈装置振动的位置。具体地，可以将屏幕垂直中线作为为基准线，并将屏幕划分为左半屏和有半屏。若根据获取到的游戏中振动事件相对于屏幕的坐标信息，确定振动事件对应坐标分布在屏幕的左半屏，则触发游戏手柄左侧的力反馈装置振动；若根据获取到的游戏中振动事件相对于屏幕的坐标信息，确定振动事件对应坐标分布在屏幕的右半屏，则触发游戏手柄右侧的力反馈装置振动。
以设置四个力反馈装置(力反馈装置A、力反馈装置B、力反馈装置C、以及力反馈装置D)为例，该四个力反馈装置可以分别设置在游戏手柄的四个角。游戏手柄可以在获取到显示游戏画面的屏幕的坐标系信息后，在游戏过程中获取游戏中振动事件相对于屏幕的坐标信息，进而确定需要触发力反馈装置振动的位置。具体地，可以将屏幕的垂直中线和水平中线为基准线，将屏幕划分为第一区域、第二区域、第三区域以及第四区域这四个区域，其中，力反馈装置A与屏幕的第一区域对应、力反馈装置B与屏幕的第二区域对应、力反馈装置C与屏幕的第三区域对应、力反馈装置D与屏幕的第四区域对应。根据游戏中振动事件相对于屏幕的坐标信息，确定振动事件对应坐标分布在屏幕哪个区域。举例来说， 若游戏中振动事件相对于屏幕的坐标信息分布在屏幕第一区域，则触发游戏手柄的力反馈装置A振动。若游戏中振动事件相对于屏幕的坐标信息在第一区域、第二区域、第三区域以及第四区域均有分布，则触发游戏手柄的力反馈装置A、力反馈装置B、力反馈装置C、以及力反馈装置D均振动。
图2为本申请另一个实施例提供的力反馈装置的结构示意图。
参照图2所示，该力反馈装置可以包括驱动机构201、振动杆202、保护帽203。其中，该驱动机构201可以驱动振动杆201以设定频率做往复运动，其中一次往复运动可以为驱动振动杆201由第一位置(保护帽203的位置)处向第二位置(返回位置)做第一运动，在振动杆202到达该第二位置后，驱动机构201驱动该振动杆202做第二运动以使振动杆202复位至第一位置，振动杆201的第一运动朝向所述第一结构，振动杆201的第二运动朝向所述第二结构，在一种实施方式中，该第一结构为图2所示的相邻结构，第二结构为图2所述的保护帽203。
在实际应用过程中，该振动杆202在往复运动过程中，具体在振动杆202做第一运动时，会出现振动杆202撞击到如图2所示的相邻结构上，即，在撞击位置204发生撞击事件，该撞击事件产生的撞击声会导致在游戏手柄100频繁出现振动事件时噪声不断，影响用户的游戏体验。
为克服上述问题，本申请实施例提供一种力反馈装置的降噪方法，通过该方法可以通过控制驱动机构201的推力和拉力的释放时机，降低振动杆202出现撞击事件的概率，从而可以降低游戏手柄使用过程中给玩家带来振感时降低其出现的噪声。
图3为本申请一个实施例提供的一种力反馈装置的降噪方法的流程示意图。
参照图3所示，该方法可以包括以下步骤：
步骤301：在振动杆做第一运动前，计算振动杆完成本次第一运动的第一时间。
其中，为实现振动杆202的第一运动，力反馈装置的驱动机构201向振动杆202提供推力，并通过该推力驱动振动杆202由第一位置运动到第二位置。在一种实施方式中，振动杆202的形状可以如图2所示，在驱动机构201向振动杆202提供推力时，振动杆202以其转动轴心转动，并转动至第二位置，在振动杆转动至第二位置后，驱动机构201向振动杆202提供拉力，并通过该拉力驱动振动杆202有第二位置返回至第一位置，从而实现控制振动杆202完成一次往复运动，其中，驱动机构201可以以设定频率驱动振动杆202完成多次往复运动从而实现振动杆以该设定频率进行振动，从而为使用该手柄的玩家提供振感，提高游戏的触觉体验。
在一种实施方式中，如图2所示，该驱动机构可以为一种电机，该电机的通过驱动杆与振动杆配合使用，该驱动杆外表面可以为螺纹结构，且该螺纹结构与控制振动杆202转动的齿轮结构配合，即驱动杆与该齿轮形成主从动关系(驱动杆主动控制齿轮从动)。进而在该电机的驱动杆向一个方向转动(例如顺时针转动)时，齿轮从动控制振动杆202由第一位置向第二位置转动以完成第一运动，在振动杆202到达第二位置后，该电机的驱动杆向反方向转动(如逆时针转动)，齿轮从动控制振动杆202由第二位置复位至第一位置以完成第二运动，进而振动杆202完成一次往复运动。
为了能够提高驱动振动杆202运动位置的精准度，具体地可以为降低振动杆202在做第一运动时撞击到下方相邻结构的可能性，可以在振动杆202进行第一运动前计算出，本次振动杆202完成第一运动所需的第一时间，从而驱动机构可以根据该预计时间控制驱动机构201的推力和拉力的释放时机，从而提高驱动振动杆202运动位置的精准度，降低振动杆202在做第一运动时撞击到下方相邻结构的可能性。
在一种实施方式中，可以基于振动杆202的第一位置信息、第二位置信息、驱动机构201的驱动强度以及修正系数计算振动杆202本次完成第一运动所需的第一时间。
其中，该具有振动功能的手柄在被用户使用前可以预先设置力反馈装置中驱动机构201的驱动强度(amplitude)以及驱动频率。在一种实施方式中，该驱动机构可以为一种用于提供力反馈的电机；因此，该驱动强度表示该驱动机构所提供力反馈的强度，即驱动力的大小。
在该手柄在被用户使用前还可以预先确定振动杆202进行第一运动和第二运动时的第一位置信息和第二位置信息。在一种实施方式中，该第一位置信息可以为如图2所示的保护帽203的位置信息，第二位置信息可以为预先设置的振动杆202进行往复运动时的返回位置的位置信息。
其中需要说明的是，该第二位置可以为振动杆202运动路线上的一个固定位置，也可以为振动杆202运动路线上不固定的位置。
在一种实施方式中，若设置第二位置为振动杆202运动路线上的一个固定位置，则在游戏中出现振动事件时，所有的振动事件触发力反馈装置振动均为振动杆202在保护帽203的位与该固定的第二位置之间进行往复运动，从而为用户提供固定的振感。
在另一种实施方式中，若设置第二位置为振动杆202运动路线上非固定位置，在实际应用过程中，在游戏中出现振动事件时，可以确定当前振动事件的振动级别，并根据当前振动事件的振动级别确定力反馈装置本次振动对应的第二位置的实际位置。
其中，可以预先对游戏中出现的振动事件进行分级，在一种实施方式中，可以基于游戏场景类型进行分级，举例来说，该振动事件的分类表如表一所示：
表一
游戏场景 振动事件等级
运动击球场景 一级振动
格斗击打场景 二级振动
驾驶撞击场景 三级振动
爆炸场景 四级振动
如表一所示，在该实施方式中可以将触发振动事件的游戏场景划分三种，分别为运动击球场景、格斗击打场景、驾驶撞击场景以及爆炸场景。举例来说，玩家通过手柄控制游戏人物击打网球时触发的振动事件的等级为一级振动；玩家在玩格斗类游戏时，玩家通过手柄控制的游戏人物被击打时触发的振动事件的等级为二级振动；玩家在通过手柄控制游戏内车辆发生撞击时触发的振动事件的等级为三级振动；玩家在玩战争类游戏时，玩家 通过手柄控制的游戏人物或载具一定范围内发生爆炸时触发的振动事件的等级为四级振动。其中，一级振动至四级振动给玩家提供的振感逐级增强。
本申请实施例并不对如何划分振动事件等级进行限制，在其他实施方式中，还可以基于其他方式划分振动等级，且振动等级数量同样不做限制。
在一种实施方式中，每个振动事件的等级所对应的第二位置不同，具体匹配方式如表二所示：
表二
振动事件等级 第二位置
一级振动 第二位置A
二级振动 第二位置B
三级振动 第二位置C
四级振动 第二位置D
如表二所示，当前振动事件对应的第二位置的实际位置根据振动事件等级来匹配。其中，一级振动对应第二位置A、二级振动对应第二位置B、三级振动对应第二位置C以及四级振动对应第二位置D。由于预设一级振动至四级振动给玩家提供的振感逐级增强，为实现振感逐级增强，可以设置不同的振动等级所对应的第二位置的实际位置不同。举例来说，可以设置力反馈装置的驱动机构201的驱动频率固定，基于不同振动事件的等级输出不同驱动强度，从而在不同的振动等级所对应的第二位置的实际位置不同的情况下，驱动振动杆202在相同或相似的时间内从第一位置运动到第二位置(第二位置A、第二位置B、第二位置C或者第二位置D)，从而为玩家不同振感。其中，振动杆202从第一位置运动到第二位置A的运动路程为L (A)、从第一位置运动到第二位置B的运动路程为L (B)、从第一位置运动到第二位置C的运动路程为L (C)、从第一位置运动到第二位置D的运动路程为L (D)。并且运动路程L (A)至运动路程L (D)逐级增长，即，L (A)＜L (B)＜L (C)＜L (D)。
在一种实施方式中，基于振动杆202的第一位置信息、第二位置信息、驱动机构201的驱动强度以及修正系数计算振动杆202本次完成第一运动所需的第一时间可以包括通过以下公式一计算：
t1＝K/A*(P2+1–P1)          公式一
其中，t1表示振动杆202本次完成第一运动所需的第一时间，P1表示第一位置信息，P2表示第二位置信息，A表示驱动机构201的驱动强度，K表示适用于当前的修正系数。
通过上述方式可以在驱动机构201驱动振动杆202进行第一运动之前计算得到振动杆202本次完成第一运动所需的第一时间t1。
步骤302：驱动机构在驱动振动杆开始第一运动起，经过第一时间后控制振动杆停止第一运动。
其中，通过步骤301计算得到振动杆202本次完成第一运动所需的第一时间t1之后，驱动机构201可以在释放推力驱动振动杆202开始进行第一运动时开始计时，并在经过t1时长后，停止释放该推力，进而可以在经过t1时长后控制振动杆202停止运动，进而可以提高控制振动杆运动的精准性，降低振动杆撞击下方相邻结构导致出现噪声的可能性。
在一些实施方式中，在振动杆202进行第二运动时，还可以计算出振动杆本次完成第二运动所需的第二时间，并基于计算得到的第二时间控制振动杆202停止第二运动，从而降低振动杆202撞击保护帽203导致出现噪声的可能性，从而提高用户体验，具体可以通过以下步骤实现：
步骤303：根据驱动机构的驱动频率计算振动杆进行第二运动所需的第二时间。
其中，该驱动机构201的驱动频率可以为用户预先设置的频率，举例来说，设置的驱动频率为2Hz，进而可以根据驱动机构201的驱动频率(如2Hz)计算振动杆202进行第二运动所需的第二时间。
在一种实施方式中，可以通过以下公式二计算振动杆202进行第二运动所需的第二时间：
t2＝1/(2*F)       公式二
其中，t2表示振动杆202进行第二运动所需的第二时间，F表示驱动机构201的驱动频率。举例来说，若驱动机构201的驱动频率是2Hz，则可以基于上述公式二计算得到振动杆202进行第二运动所需的第二时间是250ms。
通过上述方式可以在驱动机构201驱动振动杆202进行第二运动之前计算得到振动杆202本次完成第二运动所需的第二时间t2。
步骤304：驱动机构在驱动振动杆开始第二运动起，经过第二时间后控制振动杆停止第二运动。
其中，通过步骤303计算得到振动杆202本次完成第二运动所需的第二时间t2之后，驱动机构201可以在释放拉力驱动振动杆202开始进行第二运动时开始计时，并在经过t2时长后，停止释放该拉力，进而可以在经过t2时长后控制振动杆202停止运动，进而可以提高控制振动杆运动的精准性，降低振动杆撞击保护帽203导致出现噪声的可能性。
在力反馈装置需要进行往复运动实现振动的每个往复运动阶段均可以通过上述步骤301至步骤304，提高驱动振动杆202的精准性，降低振动杆202发生撞击其他结构导致出现噪声的可能性，提高用户体验。
