Abstract

A haptic feedback system is configured to be disposed on a device, and includes: a fixed portion, a movable portion, a driving assembly, and a first connecting assembly. The fixed portion is fixedly connected to the device. The movable portion is movable relative to the fixed portion. The driving assembly is configured to drive the movable portion to move relative to the fixed portion for generating feedback to the device. The movable portion is movably connected to the fixed portion via the first connecting assembly, so that the movable portion has a first vibration mode relative to the fixed portion. The driving assembly receives a first signal having a first frequency, and the first frequency is the same as the frequency of the first vibration mode.
