1. A force feedback device, wherein the force feedback device comprises a fixed portion, a button hinged to the fixed portion, an driving arm connected to a bottom of the button, and a driving assembly connected to one end of the driving arm away from the button;
the fixed portion comprises a fixed portion body and a bearing mounted at one end of the fixed portion body; the button comprises a button body and a rotating shaft formed by protruding from one end of the button body; the bearing is matched with the rotating shaft, and sleeves the rotating shaft to form a hinge structure, so that a hinge point is formed on the rotating shaft; the driving arm is connected to a bottom of the button body;
the driving assembly comprises a linear vibration motor and an output shaft extending from the linear vibration motor; the output shaft is connected to one end of the driving arm away from the button; and the linear vibration motor drives the output shaft to do linear back-and-forth motion along a vibration direction of the linear vibration motor, so that the output shaft drives the driving arm to drive the button to rotate clockwise and anticlockwise along the hinge point.
