Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, the magnetic reprimand piezoelectricity and magnetic flux of the utility model become vibration high efficiency composition power generator, including vibrating body
1 and magnet fixed frame 11, vibrating body 1 and magnet fixed frame 11 be oppositely arranged, vibration source acts on vibrating body 1, as long as have one
The vibrating object for determining frequency is all vibration source, such as: mechanical oscillation when motor field frame and pedestal, mine or road are dug, big
In wind number wood swing vibration, the hull on wave, buoy shake etc. vibration the energy, on vibrating body 1, with magnet fixed frame 11
Opposite side is fixed with one end of spring bed 2 and one end of piezoelectric board 3, spring bed 2 are integrated with piezoelectric board 3, elasticity
Supporting plate 2 and piezoelectric board 3 are vertical with the direction of vibration of vibrating body 1, and the piezoelectric board 3 is compound on single layer of piezoelectric material plate 6
Multi-layer piezoelectric plate of material 7 is constituted, and 2 top of spring bed is compounded with single layer of piezoelectric material plate 6,6 top of single layer of piezoelectric material plate
Be compounded with multi-layer piezoelectric plate of material 7, the length of multi-layer piezoelectric plate of material 7 is less than single layer of piezoelectric material plate 6, when piezoelectric board 3 by
When external force generates strain, charge is enriched with to material surface, is generated electromotive force, is externally exported electric energy, realize stress-
Strain-electric energy transformation function, spring bed 2 in vibration, closer to 3 root of piezoelectric board of vibrating body 1, are got over by torque
Greatly, the pulling force on 2 section of spring bed or pressure are bigger, because the ratio between stress and sectional area are stress, difference on uniform thickness piezoelectric board 3
Stress and strain value at distance is different, and the stress of 3 root of piezoelectric board is greater than the stress at free end position, leads to piezoelectric board
The strain of 3 different parts and surface charge enrichment are uneven, and according to Varying-thickness piezoelectric board 3, close to root stress, big, plate is got over
Thickness, the thickness close to free end plate become smaller, and realize iso-stress stress design principle, so the enrichment of 3 surface charge of piezoelectric board is more
Uniformly, between spring bed 2 and single layer of piezoelectric material plate 6, between single layer of piezoelectric material plate 6 and multi-layer piezoelectric plate of material 7 and most
The top of upper layer multi-layer piezoelectric plate of material 7 is equipped with electrode paste 10, and the length of piezoelectric board 3 is less than spring bed 2, after stress,
3 surface enrichment charge of piezoelectric board disposes electrode paste 10 charge current can be connected in outer lead circuit thereon；It is held in the palm in elasticity
The other end of plate 2 is fixed with counterweight magnet 8, is mechanical-physical connection between spring bed 2 and counterweight magnet 8, so elasticity support
Connected between plate 2 and counterweight magnet 8 using modes such as mechanical bindings, be fixed on magnet fixed frame 11 fixed magnet 9,
And be oppositely arranged with counterweight magnet 8, the same pole of counterweight magnet 8 and fixed magnet 9 is staggered relatively, and magnet counterweight can reduce pressure
The intrinsic frequency resonance point of battery plate 3 changes the parameter linear functional relation of 3 vibrational system of former piezoelectric board, introduces outside nonlinear magnetism
Power generates non-linear repulsive force, improves system electromechanics relevance, is easy to capture and rectification of the circuit system to alternating potential energy,

In the same horizontal line, vibration source drives matching for its free end by spring bed 2 for magnet 8, induction coil 5 and fixed magnet 9
Weight magnet 8 is swung, so that the magnetic flux between counterweight magnet 8 and fixed magnet 9 is presented with the mechanical periodicity of vibration frequency, according to electricity
Magnetic induction principle, it will generated in induction coil 5 using vibration frequency as the mutation induced current in period, induction coil 5 is sense
It should be galvanically connected in outer lead circuit, while the broadband coupled coefficient of nonlinear magnetism reprimand piezoelectricity improves, fixed magnet 9 is received
To the repulsive interaction of the counterweight magnet 8 of swing, there is alternately variation phenomenon in periphery magnetic field strength, before fixed magnet 9
Coil 5 is added, the electric current induced by the variation of magnetic field strength magnetic flux will be generated in coil 5, so this coil 5 is set
Setting will make counterweight magnet 8 generate two different generating mechanisms, first is that the bandwidth for widening piezoelectric system improves electromechanical coupling factor,
