进一步的，所述触控面板上设有若干用于输入触控动作的触控部。

附图说明

图2为本发明触控面板分区分级控制示意图。
具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征更易被本领域技术人员理解，从而对本发明的保护范围作出更为清楚的界定。
实施例1：
本实施例提供一种触控面板振动反馈装置，包括触控面板4、检测模块5、若干振动模块1、若干控制模块2及供电模块3；检测模块5设置在触控面板4下方，检测模块5用于接收触控信号并将其传输至控制模块2。各控制模块2分别藕接于检测模块5与各振动模块1之间，根据触控信号调整对应振动模块1的振动特性，振动模块1可以为振动电机或压电致动器，本实施例所用振动模块1为振动电机。供电模块3用于对控制模块2及振动模块1提供工作电能。其中，各振动模块1可设有若干振动等级，所述触控面板4设有若干触控区域，各触控区域与至少一个振动模块1的特定振动等级相匹配。本实施例中设有两个振动模块1，各振动模块1分别设有4个振动等级，上述两个振动模块1设于触控面板4的对角位置，触控面板4以振动模块1为中心点，以距离振动模块1的直线距离为半径，围绕两个振 动模块1分别划分有四个区域，划分的区域覆盖了整个触控面板4。上述振动等级与距离振动模块1的直线长度成正比，距离振动模块1的直线长度越小，振动模块1的振动等级越低，振动强度越小，而距离振动模块1的直线长度越大，振动模块1的振动等级越大，振动强度也越高，但由于振动强度在传播过程中随直线长度的增加而逐渐减弱，这就使得距离振动模块1较远区域与距离振动模块1较近区域具有相同的振动效果。其中，各振动模块1在同一位置产生的振动强度可相互叠加，且叠加后的振动强度使各触控区域产生的振动效果相同。各触控区域产生的振动效果可以通过改变对应各振动模块1的振动强度、振动速度及振动时间进行调节，使产品振动反馈手感值可以满足不同客户的需求。
实施例2：
本实施例与实施例1类似，进一步的，触控面板4上还可设有若干触控部，各触控部用于客户输入触控动作。在本实施例中，触控面板4上设有18个触控部，且18个触控部依据其与各振动模块1的直线长度分布在相应的区域内，与至少一个振动模块1的特定振动等级相匹配，各振动模块1在同一位置产生的振动强度相互叠加，叠加后的振动强度使各触控部产生的振动效果相同，手感均匀一致。
实施例3：
一种触控面板振动反馈的控制方法，基于上述一种触控面板振动反馈装置，包括如下步骤：
S1、将各所述振动模块1预设为若干振动等级，所述振动等级与距离振动模块1的直线长度成正比；
S2、将所述触控面板4划分为若干触控区域；
S3、根据不同触控区域与各所述振动模块1的直线长度，将触控区域分别与各振动模块1的振动等级相匹配，各所述振动模块1在同一触控区域的振动效果相互叠加；
S4、检测模块5接收输入的触控信号，并根据触控信号与振动等级信号的匹配结果，将触控信号传输至相应控制模块2；
S5、所述控制模块2调整对应振动模块1的振动特性，使其输出特定等级的振动强度。
其中，各振动模块1在同一触控区域产生的振动效果可叠加，叠加后各触控区域的最终振动效果完全相同。各触控区域的振动效果均可通过改变相应振动模块1的振动强度、振动速度及振动时间进行调节，可以满足不同客户的要求。
实施例4：
本实施例与实施例3类似，进一步的，上述检测模块5在接收输入的触控信号之前还 对触控信号进行了相关滤波处理，滤除杂波，得到有用信息，提高触控信号输入的有效性。
上面结合附图对本发明的实施方式作了详细说明，但是本发明并不限于上述实施方式，在本领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下作出各种变化。
