Specifically, taking one direction as an example, when the rocker 100 moves in the X direction, the rocker 100 can move in both the X positive direction and the X negative direction, and the piezoelectric module 200 can be placed in the X positive direction. When the rocker 100 moves in the X-direction, the piezoelectric module 200 is squeezed, the piezoelectric module 200 outputs a compression electrical signal, and the larger the compression electrical signal is, the larger the squeezing force of the rocker 100 on the piezoelectric module 200 is, and the larger the rocker 100 deflects in the X-direction; when the rocker 100 moves in the X negative direction, the piezoelectric module 200 is stretched, the piezoelectric module 200 outputs a stretching electrical signal, the larger the stretching electrical signal is, the larger the tension of the rocker 100 on the piezoelectric module 200 is, the larger the rocker 100 deflects in the X negative direction, and thus the movement direction of the rocker 100 can be determined. Meanwhile, the rocker structure is structurally characterized in that 1 piezoelectric module is only designed in the motion direction, the rocker structure is simplified, and the main board collects the compression electric signals and the stretching electric signals of each piezoelectric module to judge the moving position of the rocker.

When the rocker 100 moves in the positive X direction, the piezoelectric module 200 in the positive X direction is squeezed, the piezoelectric module 200 in the positive X direction outputs a compression electrical signal, and the larger the compression electrical signal is, the larger the squeezing force of the rocker 100 on the piezoelectric module 200 in the positive X direction is, and the larger the rocker 100 is shifted in the positive X direction; when the rocker 100 moves in the X negative direction, the piezoelectric module 200 in the X negative direction is squeezed, the piezoelectric module 200 in the X negative direction outputs a compression electric signal, the larger the compression electric signal is, the larger the pressure of the rocker 100 on the piezoelectric module 200 in the X negative direction is, the larger the deflection of the rocker 100 in the X negative direction is, and thus the movement direction of the rocker 100 can be determined.
