CONSTITUTION: An electric module for skin irritation comprises a base unit(110) in which a power terminal interconnects the skin of a human body to a conductor, a vibrator(120) installed on one side of the base unit, a drive unit(130) which is installed in base unit and comprises a rotary shaft and a coil, a drive switch for switching on and off the power source of the drive unit, a control unit(150) for controlling the vibration state of the vibrator, and an induced electromotive force processing unit.
Abstract:
PURPOSE: A power supplying apparatus and a self generating type remote controller including the same are provided to backwardly forwardly move a weight part based on a driving shaft by applying elastic restoring force to the weight part. CONSTITUTION: A power supplying apparatus(2000) corresponds to the power supplying part of a self generating type remote controller. The power supplying apparatus includes a base(100), a generating part, a speed increasing gear part, a power storing element, a weight part(150), and an elastic member(160). The generating part converts mechanical energy into electric energy. The generating part receives the backward-forward movement of the weight part through a driving shaft. The base is combined with the upper side of the generating part. A supporting part(110) is combined with one side of the flange part of the base. The weight part is combined with the outer circumference of an inscribed gear(320). The elastic member is a compressive coil spring interposed between the weight part and the supporting part.
