Referring to fig. 4-5, an electronic watch is taken as an example for explanation, and other embodiments of wearable electronic devices are similar to the electronic watch. The vibration of human body during activity mainly comes from the following aspects: (1) the person can float up and down due to the change of the body gravity center when walking; (2) the natural swing of the arm of the person during walking; (3) the swinging of the arms of a person during other everyday activities (e.g., picking and placing things, natural movement of limbs, exercise, driving a car, tapping a keyboard, etc.). These vibrations have their own specific frequency range and occur with a high probability and are present in almost everyone's life.
One of the core ideas of the invention is to provide an electric energy conversion device, convert the vibration generated by the human body during walking and daily activities into electric energy, and supply the electric energy to the wearable electronic equipment for use, so as to save trivial time brought by charging the wearable electronic equipment and fully utilize energy dissipated by the human body activities.

The vibrating pieces 5 connected with the four side surfaces are arranged in a parabolic direction, and the size and the quality of each vibrating piece 5 can be different according to needs, so that the frequency range of daily activities and walking of a human body can be covered as far as possible.

Preferably, the positioning unit is connected in series with the energy storage battery and in parallel with the consumer. The invention has two working states, one is that the switch d is disconnected, the electric energy conversion device is not connected, and the control unit is in the state when judging that the electric quantity of the energy storage battery is higher than the charging trigger electric quantity; the other is a connection switch d, which is in the state when the control unit judges that the energy storage battery needs to be charged. The two working states have three working modes, and the difference is whether the electric element and the positioning unit work or not. When in the charging working state: the first mode is to turn on the switches a and d, and only the electric element is used for working at the moment; the second mode is to switch on the switches b and d, and only the positioning unit works at the moment; the third mode is to switch on the switches a, b and d, and at the moment, the electric element and the positioning unit work together; the three mode control units and the electric energy conversion device are all in working states. When in the non-charging working state: the first mode is to turn on the switches a and c, and only the electric element works at the moment; the second mode is to switch on the switches b and c, and only the positioning unit works at the moment; the third mode is to switch on the switches a, b and c, and at the moment, the electric element and the positioning unit work together; the three working mode control units are all in working states.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
