Wrist training ball and information display and detecting module thereof

Abstract

A wrist training ball includes a housing, a rotating body rotatably disposed in the housing, a magnetic component and an information display and detecting module. The magnetic component, disposed at the rotating body, spins with the rotating body. The information display and detecting module, disposed at the housing, includes a sensing unit, a rectifying unit, a signal transforming unit and a processing unit. The sensing unit generates an induced current when the rotating body is spun. The rectifying unit, electrically connected to the sensing unit, rectifies the induced current into an operating power. The signal transforming unit, electrically connected to the sensing unit, transforms the induced current into a motion datum. The processing unit, electrically connected to the rectifying unit and the signal transforming unit, receives the operating power for operation and processes the motion datum to determine a relative motion relationship between the rotating body and the housing.
