Dynamic amplitude is different, and the 5th interconnecting piece 445 can be jacked up by the bigger adjusting unit 433 of Oscillation Amplitude, that is to say, that the 5th connects at this time
Socket part 445 is only vibrated the biggish effect for adjusting unit 433 of amplitude, and the 5th interconnecting piece 445 is conditioned the jack-up of unit 433
When, at the same by upwardly and laterally and be directed toward amplitude it is maximum adjust 433 direction of unit power, therefore, the 5th interconnecting piece 445 to
While upper movement, gradually moved to maximum 433 side of adjusting unit of amplitude, i.e., the 5th interconnecting piece 445 always progressively disengages
The lesser adjusting unit 433 of Oscillation Amplitude, and then the biggish influence for adjusting unit 433 of vibrated amplitude, are gradually moved to vibration
The dynamic highest top for adjusting unit 433 of amplitude；After being moved to maximum 433 top of adjusting unit of Oscillation Amplitude, the 5th connection
Portion 445 no longer moves, and interactive module 44 and the contact position of cantilever beam 421 change at this time, the intrinsic vibration of cantilever beam 421
Frequency also changes correspondingly.
Several adjusting units 433 will be set in adjustment module 43, so that the adjacent natural resonance frequency for adjusting unit 433 is equal
Difference must have 433 Oscillation Amplitude of adjusting unit maximum under some vibration frequency, in vibration processes, adjust unit
Under the action of 433, interactive module 44 is gradually moved, until being moved at the maximum adjusting unit 433 of Oscillation Amplitude, so that
The contact position of interactive module 44 and energy conversion module 42 changes, to change the intrinsic frequency of energy conversion module 42, makes
Energy conversion module 42 eigentone close to compressor bottom board vibration frequency so that energy conversion module 4 can be with
In a broader frequency ranges of operation, electric energy is converted by more mechanical energy convenient for energy conversion module 4.
