  • this force sense There are currently two ways to achieve this force sense: one is to input an asymmetric signal into the linear resonator and use the human senses to create an illusion. In principle, this method can only produce a continuous directional force sense and cannot achieve discrete vibration output. At the same time, the equivalent force felt in this way is small, and the asymmetric signal will also produce redundant vibrations, making it difficult to obtain a clear sense of direction.

Description

激励器和电子设备 技术领域
本发明涉及振动装置技术领域，特别涉及一种激励器和应用该激励器的电子设备。
背景技术
传统的振动装置通过不断制造非对称振动，产生“仿佛朝向某一个方向”的作用力的错觉，此类振动又被称为异向性振动。
目前有两种实现该力感的手段：一种是向线性谐振器输入不对称信号，并利用人类感官产生错觉的方法。此种方式原则上只能产生持续的定向力感，不能实现离散的振动输出。同时，通过此种方式感受到的等效力较小，非对称信号也会产生多余的振动，因而难以获得清晰的方向感。另一种是通过快速制动线性谐振器来产生强力的力感。此种方法能生成非对称性大的振动，并且有多余振动比例小，力感单独且清晰的特点。但是，此方法需要由振动部和制动部分别独立构成，并不断的移动振动部或制动部位来切换蓄能和制动状态，导致其无法高速连续动作，且装置结构复杂。

传统的振动装置通过不断制造非对称振动，产生“仿佛朝向某一个方向”的作用力的错觉，此类振动又被称为异向性振动。
目前有两种实现该力感的手段：一种是向线性谐振器输入不对称信号，并利用人类感官产生错觉的方法。此种方式原则上只能产生持续的定向力感，不能实现离散的振动输出。同时，通过此种方式感受到的等效力较小，非对称信号也会产生多余的振动，因而难以获得清晰的方向感。另一种是通过快速制动线性谐振器来产生强力的力感。此种方法能生成非对称性大的振动，并且有多余振动比例小，力感单独且清晰的特点。但是，此方法需要由振动部和制动部分别独立构成，并不断的移动振动部或制动部位来切换蓄能和制动状态，导致其无法高速连续动作，且装置结构复杂。
然而，该类装置只实现了直线方向的振动，无法产生旋转方向的力感。

需要说明的是，当第一旋转部22/第二旋转部32运动至极限位置时，第一旋转部22/第二旋转部32对壳体1的冲击力相互平行且力臂相等，从而实现单纯的顺时针旋转触感的效果。当第三旋转部42/第四旋转部52运动至极限位置时，第三旋转部42/第四旋转部52对壳体1的冲击力相互平行且力臂相等，从而实现单纯的逆时针旋转触感的效果。

当然，第三旋转部42和第四旋转部52顺时针旋转与第一隔板14撞击时，第三旋转部42和第四旋转部52对壳体1所产生的两个冲击力，与第三旋转部42和第四旋转部52的质心连线相重合，从而使得壳体1受到两个大小相同、方向相反的作用力，从而实现运动冲击抵消的效果。另一个状态下，也即第三旋转部42和第四旋转部52逆时针旋转与第一侧壁12和第二隔板15撞击时，第三旋转部42和第四旋转部52对壳体1的冲击力相互平行力臂相等，从而实现单纯的逆时针回转触感的效果。
在实际使用过程中，可综合利用同一回转的两个极限，也可根据结构的拆分使得其中一组力臂更长，从而获得更优质的触觉反馈，在此不做限定。
