Detailed description of the invention

In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, rightThe present invention is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the present invention, andBe not used in restriction the present invention.

Specific embodiment one

Please refer to Fig. 1, Fig. 2, Fig. 3, a kind of vibrating electricity generator, has stepped hole 32, magnet structure in shell 3 hollow cavities 33Part 2 is placed in stepped hole; There is a sleeve 1 upper end of magnet structure 2, and this sleeve 1 is placed in the upper end platform of shell 3 hollow cavities 33In hole, rank 31; Movable part is made up of motion bar 4, spring 5, and one end of spring 5 is placed on the shaft shoulder 42 of motion bar, and one end is placed inThe bottom of shell 3 hollow cavities 33, these spring 5 external diameters are slightly less than shell hollow cavity 33 internal diameters; Coil 6 is fixed on motion bar 4On groove 44 in, motion bar 4 inside are provided with fairlead 43, the contact conductor of coil 6 61 is not through fairlead 43 and battery (in figureIllustrate) electrical connection.

Magnet structure 2 is formed by some magnetic Component compositions. Each magnetic member by base 22 and at least one pair of magnet to 21 groupsBecome, magnet is fixed on base 22 21. Magnet is made up of two magnet 21, and each magnet N, S are corresponding.
