With reference to the accompanying drawings said process is elaborated.
At first, the present invention such as Figure 16, shown in Figure 17, the electromagnetic field of the magnetic field of magnetic circuit 2 and above-mentioned coil 3 interacts; Under the support of elastic support 4, carry out along the AC signal direction of coil 3 producing vibration force in the process of straight line back and forth movement, owing to be provided with graviational interaction device 11 on the cabinet 1; At magnetic circuit 2 on the direction of motion that graviational interaction device 11 directions move; There is the attractive interaction effect between magnetic circuit 2 and the graviational interaction device 11, that is, and under the magneticaction of magnetic circuit 2; The graviational interaction device of being processed by magnetic material 11 is magnetized, thereby attracts each other.
Like this, the pressure that under the state along with the signal natural vibration of coil 3, receives magnetic force attracts, and therefore, compares common vibrational state, and its acceleration of gravity strengthens.So, reach the best part at acceleration of gravity and form near resonance point (acceleration of gravity reaches maximum point, forming the principle of resonance point).
At this moment; Under the graviational interaction between graviational interaction device 11 and the magnet 2b, when opposite direction is vibrated, perhaps can think by error because graviational interaction can make vibration force reduce; But with draw back bowstring after principle when discharging identical; Elastic support 4 overcomes the gravitation At time of eject, and acceleration of gravity still increases, thereby improves vibration force.
The resonance point that above-mentioned acceleration of gravity and acceleration of gravity produce can be adjusted through the diameter or the thickness of graviational interaction device 11.That is,, can revise resonance point through the diameter or the thickness of the above-mentioned graviational interaction device 11 of artificial adjusting.
This point can obtain checking from experimental result table (vary in diameter) shown in Figure 180, below explanation is when the fiducial value of required resonance point (resonance frequency) is 175Hz, and acceleration of gravity is to carry out under the above hypothesis of 1.3g.
With the first time experimental result be example, the finished product initial stage Characteristics Detection result of certain induced signal output equipment 10 shows that resonance point (resonance frequency) is 180.5Hz, the acceleration of gravity that 175Hz is corresponding is 0.74g.Because resonance point is compared fiducial value and is wanted high, when the required 175Hz of product, have less acceleration of gravity, do not reach the requirement that when 175Hz acceleration of gravity reaches 1.3g at least, belong to defective item.
But, when graviational interaction device 11 of the present invention being attached to side of cabinet 1 of above-mentioned induced signal output equipment 10, for example shown in the category-A; Having attached diameter is 3 θ; After thickness was the graviational interaction device 11 of 0.025t, resonance point (resonance frequency) was 178Hz, and acceleration of gravity is 1.14g.This is equivalent to resonance point has been reduced 2.5Hz, be adapted in the resonance point error range, and the acceleration of gravity that 175Hz is corresponding has improved 0.4g.
In addition, shown in category-B, having attached diameter is 4.7 θ, and after thickness was the graviational interaction device 11 of 0.025t, resonance point (resonance frequency) was 175.5Hz, and acceleration of gravity is 1.37g.This is equivalent to resonance point has been reduced 5Hz (being adapted in the error range), almost satisfies the requirement of benchmark resonance point, simultaneously acceleration of gravity has been improved 0.63g.
On the other hand, the present invention is shown in figure 19 to the experimental result table of varied in thickness, and is identical when below explanation is tested with vary in diameter, supposes that required resonance point (resonance frequency) is 175Hz, and acceleration of gravity is more than the 1.3g.
With the first time experimental result be example, the finished product initial stage Characteristics Detection result of certain induced signal output equipment 10 shows that resonance point (resonance frequency) is 178.5Hz, the acceleration of gravity that 175Hz is corresponding is 0.97g.Because this resonance point is compared fiducial value and is wanted high, at the required 175Hz of product, has less acceleration of gravity, do not reach the requirement that when 175Hz acceleration of gravity reaches 1.3g at least, belong to defective item.
But; When graviational interaction device 11 of the present invention being attached to side of cabinet 1 of above-mentioned induced signal output equipment 10; For example shown in the category-A, having attached diameter is 3 θ, after thickness is the graviational interaction device 11 of 0.025t; Resonance point (resonance frequency) is 176.9Hz, and acceleration of gravity is 1.46g.This is equivalent to resonance point has been reduced 1.6Hz, be adapted in the resonance point error range, and the acceleration of gravity that 175Hz is corresponding has improved 0.49g.
In addition, shown in category-B, having attached diameter is 3 θ, and after thickness was the graviational interaction device 11 of 0.04t, resonance point (resonance frequency) was 174.4Hz, and acceleration of gravity is 1.47g.This is equivalent to resonance point has been reduced 4.1Hz, has been adapted in the resonance point error range, and simultaneously that 175Hz is corresponding acceleration of gravity has improved 0.5g.
The resonance point correction state that carries out through above-mentioned graviational interaction device 11 can compare through curve shown in figure 20.From curve, can find out; The initial stage characteristic of certain induced signal output equipment is shown as, and resonance point is 178.5Hz, and the acceleration of gravity that 175Hz is corresponding is 0.92g; But having attached diameter is 3 θ; After thickness was the graviational interaction device 11 of 0.02t, resonance point had moved down into 177Hz, and the acceleration of gravity that 175Hz is corresponding has been adapted to 1.38g; Having attached diameter is 4.2 θ; After thickness is the graviational interaction device 11 of 0.02t; Resonance point has moved down into 175Hz, and acceleration of gravity has been adapted to 1.68g, and (that use on the curve as a reference, is not g (9.8m/s^2); But m/s^2, therefore what just can obtain above-mentioned explanation is the numerical value of unit with g divided by 9.8).
As stated; The present invention can only through dismounting (comprising replacing) graviational interaction device 11, get final product people's acceleration of gravity for a change under the finished product or greenware condition of induced signal output equipment 10; Resonance point is regulated, thereby can be revised the error of output characteristic at an easy rate.In addition, the present invention can revise the error of output characteristic under finished product state, can significantly reduce disqualification rate.
More than combined the preferred embodiments of the present invention that the present invention is specified and illustrates, but the present invention is not limited thereto, its hardware scope that is suitable for also is not limited to this.Under the prerequisite that does not break away from described invention thought of claims and category, can carry out numerous variations and correction to the present invention.Therefore, the equivalent that obtains through above-mentioned change and correction also should belong to the scope of claim of the present invention.
