Abstract
A wireless mouse apparatus includes a mouse wheel module and an encoder signal processing and induced electromotive force processing circuit. The mouse wheel module includes a mouse wheel, two stator plates, a plurality of coils and a rotation shaft. The mouse wheel includes a multipolar magnetic body. The coils are arranged on the stator plates. The rotation shaft is connected to the mouse wheel and the stator plates. The encoder signal processing and induced electromotive force processing circuit is used for decoding two signals of phase lead or lag produced representative of rotating of the mouse wheel in the two directions of scroll down or scroll up. The encoder signal processing and induced electromotive force processing circuit converts the alternating current induced electromotive forces into direct current induced electromotive forces and then stores in an energy storing apparatus.
