The neighboring of coil 30 and above-mentioned yoke 30 is separated by and set, and the flowing in the magnetic field of magnet 70 is concentrated, to pass through above-mentioned spring 50
Elastic reaction when vibrating along the vertical direction, in middle thereof in above-mentioned vertical projections 11, above-mentioned coil 30 and yoke 30
Vibrated along the vertical direction under state；
Magnet 70, as vibrating body, be incorporated into the upper plane of above-mentioned plate 60, inner rim from above-mentioned vertical projections 11,
The neighboring of above-mentioned coil 30 and above-mentioned yoke 30 is separated by and set, and magnetic field is produced by the effect with coil 40, to produce up and down
Vibration, with when the elastic reaction by above-mentioned spring 50 vibrates along the vertical direction, in middle thereof in above-mentioned vertical projections
11st, vibrated along the vertical direction in the state of above-mentioned coil 30 and above-mentioned yoke 40；
Pouring weight 80, as vibrating body, tied with the top of above-mentioned spring 50 and above-mentioned magnet 70 in the neighboring of above-mentioned plate 60
Close, in above-mentioned 50 up-down vibration of spring, above-mentioned magnet 70 and plate 60 is more firmly fixed on above-mentioned spring 50, pass through itself
Weight amplification vibration；
Top casing 90, it is incorporated into the top edge of above-mentioned yoke 10 and is formed in the form of downwardly open lid,
To form outer cover when being combined with above-mentioned yoke 10.
Above-mentioned yoke 10 is combinative to possess F-PCB20, coil 30 and spring 50, including plane central portion is to top
Prominent vertical projections 11, and combined with top casing 90.

Fraction defective is combined less.
Now, as shown in figure 4, above-mentioned yoke 10 can make the periphery a2 thickness of above-mentioned vertical projections 11 more than outer
More than the 50% of sidepiece a1 thickness.
Now, as shown in Figure 5 to Figure 6, Fig. 5 is when the week for the vertical projections 11 for being arranged to make Fig. 4 by yoke 10
When edge a2 thickness is identical with outside portion a1 thickness, electromagnetic force measurement image document schematic diagram, Fig. 6 is to work as yoke branch
During the half of thickness that the thickness that frame 10 is arranged to the periphery a2 for the vertical projections 11 for making Fig. 4 is outside portion a1, electromagnetic field
Power measures image document schematic diagram, if comparing Fig. 5 and Fig. 6 electromagnetic force survey data, it is known that than Fig. 5 Fig. 6 electromagnetic field
Power measured value is higher because above-mentioned vertical projections 11 periphery a2 thickness be more than outside portion a1 thickness 50% with
When upper, with the increase of the power of electromagnetic field, the power for forming magnetic field about improves 20% than the up-down vibration motor of prior art.
I.e. because caused by the saturated phenomenon of magnetic field, periphery a2 thickness it is thinner (the 50% of outside portion a1 thickness with
Under), electromagnetic field mobility degenerates caused by the saturation of magnetic field, and its thickness is thicker (more than the 50% of outside portion a1 thickness), magnetic field
Saturated phenomenon disappears, and electromagnetic field mobility improves, and utilizes above-mentioned phenomenon to can control about the 20% of electromagnetic force.
An above-mentioned F-PCB20 sidepiece runs through above-mentioned vertical projections 11 and is incorporated into the flat of above-mentioned yoke 10
Face, external power source is supplied to coil 30.
The above-mentioned middle thereof of coil 30 is in above-mentioned vertical projections 11 and is vertically integrated in above-mentioned F-PCB20 plane, leads to
Cross the vertical vibration that the effect with magnet 70 produces vibrating body.
Therefore, coupling coil 30 can be penetrated around above-mentioned vertical projections 11, so as to easily combine above-mentioned yoke
Support 10 and coil 30, process management become simple, and reduction combines fraction defective.
The above-mentioned middle thereof of yoke 40 is in the above-mentioned plane for projecting upwards portion 11 and being incorporated into above-mentioned coil 30, with concentration line
The flowing of the internal magnetic field of circle 30.
Now, above-mentioned yoke 40 can annular form so that middle thereof projects upwards portion 11 and be incorporated into above-mentioned in above-mentioned
The plane of coil 30.
Therefore, Yoke-integrated 40 can be penetrated around above-mentioned vertical projections 11, so as to easily combine above-mentioned yoke
Support 10 and yoke 40, process management become simple, and reduction combines fraction defective.
