Thesensing unit 530 is disposed on thecircuit board 520 by thehook 531 which is fastened to thecircuit board 520. In this embodiment, thesensing unit 530 comprises a plurality of coils. Because the information display and detectingmodule 500 is fixedly disposed at thehousing 100, when therotating body 200 is spun with respect to thehousing 100, themagnetic component 400, which is disposed at therotating body 200, is accordingly spun in relative to the information display and detectingmodule 500 disposed at thehousing 100. Therefore, themagnetic component 400 generates a relative movement in relative to thesensing unit 530 of the information display and detectingmodule 500, a changing of the magnetic force (i.e., magnetic force changing) is generated in relative to the sensing unit 530 (that is, the changing of the magnetic flux passing through the sensing unit 530). Consequently, thesensing unit 530 generates an induced current according to the Faraday's Law of Induction. - The rectifying
unit 540, thepower storage unit 550, thesignal transforming unit 560, theprocessing unit 570 and theinput unit 590 are all disposed on thecircuit board 520. The rectifyingunit 540 is electrically connected to thesensing unit 530. Thesignal transforming unit 560 is electrically connected to thesensing unit 530. The rectifyingunit 540 and thesignal transforming unit 560 are respectively coupled to thesensing unit 530. The rectifyingunit 540 is configured to rectify the induced current generated by thesensing unit 530 into an operating power. Thesignal transforming unit 560 is configured to transform the induced current generated by thesensing unit 530 into a motion datum. Thepower storage unit 550 is electrically connected to the rectifyingunit 540 and theprocessing unit 570, so theprocessing unit 570 is electrically connected to the rectifyingunit 540 via thepower storage unit 550. Thepower storage unit 550 is configured to store the operating power which is rectified by the rectifyingunit 540 and also configured to supply the operating power for theprocessing unit 570. As shown inFIG. 3B , in this embodiment, thepower storage unit 550 comprises a capacitor, and the power stored by thepower storage unit 550 may provide a supply voltage Vcc for theprocessing unit 570. Theprocessing unit 570 is electrically connected to thesignal transforming unit 560. Theprocessing unit 570 is configured to receive the operating power for operation and is also configured to process the motion datum to determine a result of a relative motion relationship between therotating body 200 and thehousing 100. For example, the relative motion relationships are the rotating speed, rotation revolutions, acceleration and angular acceleration of therotating body 200 in relative to thehousing 100. Thedisplay unit 580 is electrically connected to theprocessing unit 570. Theprocessing unit 570 is also configured to control thedisplay unit 580 to display the result of the relative motion relationship between therotating body 200 and thehousing 100 with respect to the changing of the magnetic force. In this embodiment, thedisplay unit 580 comprises a display portion and a backlight portion disposed on the display portion (not shown). The backlight portion helps the user to read messages shown on the display portion. Furthermore, theprocessing unit 570 is also configured to calculate the time of rotations of therotating body 200, that is, the time of operation of thewrist training ball 10. Theinput unit 590 is disposed on thecircuit board 520 and is electrically connected to theprocessing unit 570. As shown inFIG. 3B , in this embodiment, theinput unit 590 is electrically connected to thesignal transforming unit 560. In other embodiments, theinput unit 590 and thesignal transforming unit 560 are independently disposed to be separated by a distance. Abutton 591 is disposed on themain body 510 and corresponds to theinput unit 590. When thebutton 591 is pressed, theinput unit 590 is triggered, and theinput unit 590 transmits an input signal to theprocessing unit 570. Theprocessing unit 570 switches the content of thedisplay unit 580 according to the input signal. For example, when thebutton 591 is pressed, theprocessing unit 570 controls thedisplay unit 580 to switch and display the result of the relative motion relationship and the time of operation. Furthermore, theprocessing unit 570 may reset the time of operation according to the input signal. - In other embodiments, the information display and detecting
module 500 does not comprise thepower storage unit 550, and the rectifyingunit 540 is directly and electrically connected to theprocessing unit 570. The operating power which is rectified by the rectifyingunit 540 directly supplies power for theprocessing unit 570. - As shown in
FIG. 2 , when thewrist training ball 10 is operated, the user may control a starting device (not shown) to provide an initial kinetic energy for therotating body 200. For example, the starting device is a pulling cord, a rack or a generator. The starting device is in contact with therotating body 200 via theopening 101 so as to make therotating body 200 spin (namely, rotate), thereby providing the initial kinetic energy for therotating body 200. During the operation of thewrist training ball 10, therotating body 200 is spun to make themagnetic component 400 spin accordingly such that thesensing unit 530 generates the induced current. As shown inFIG. 3 , some of the induced current is rectified into the operating power by the rectifyingunit 540, and the operating power is supplied for theprocessing unit 570 to operate. Thesignal transforming unit 560 may output the motion datum according to the induced current and the amplitude thereof. Therefore, theprocessing unit 570 is configured to determine the relative motion relationship between the rotating body and the housing with respect to the changing of the magnetic force. The larger the frequency of the induced current is, the faster the rotating body spins. - According to the wrist training ball disclosed in this embodiment, because of the induction effect between the magnetic component disposed at the rotating body and the information display and detecting module disposed at the housing, the sensing unit generates the induced current according to the changing of the magnetic force. The processing unit is configured to rectify the induced current that is received form the rectifying unit into the operating power as well as configured to receive the motion datum that is transformed from the induced current by the signal transforming unit. When the user operates the wrist training ball, the processing unit may receive the operating power from the induced current and the motion datum from the induced current at the same time. As long as the user operates the wrist training ball, the information display and detecting module is operated and performs detecting without other sources of power (does not need other power supply). Because the sensing unit is electrically connected to the processing unit via the signal transforming unit as well as via the rectifying unit, the processing unit not only obtains the motion datum of the rotating body according to the induced current but also receives the operating power from the induced current. Therefore, the wrist training ball according to the disclosure saves energy and avoids the inconvenience of the user and environmental pollution resulted from the replacing of battery.
