The magnitude of the centrifugal force the magnetic number 1 (121) number 2 on magnetic (122) magnitude that is greater than the magnetic attractive force between number 2 (122) includes a magnetic number 1 (121) from separating from the other. The, magnetic number 1 (121) one end of magnetic number 2 (122) with a rim (R) which is securely mounted in the magnetic number 2 (110) is number 1 magnetic (121) even when barrier from dislodging from the (110) and at their other ends are rotated circumferentially only by fixing one end of the tread portion of (T) inside of tire cavity (cavity) in contact with the inner surface of the light-shielding substrate. Operation of the device of the present invention number 1 in the embodiment according to tire resonance noise reduction are disclosed other withdrawals now. First, prior to operation of the device of the present invention number 1 in the embodiment according to the above-described tire resonance noise reduction are disclosed, resonance noise is described substrate. Tire resonant noise the running of a vehicle, road surface upon rotation of the impact happens from more accurate tire, tire and rim generated by spiral penetration cavity between and computer program product to be coated. One such tyre resonant noise high peak of ride comfort by speaker is lowered to a value. Such resonance noise tire circumferential direction length determined by sonic, to equation according to disclosed. Where f is frequency and resonant noise, C is sonic, tire radius R big. In such resonance noise wheel structural portion which, various method cannot substantially resonance electromagnet film because of the same resonance frequency noise through resonance noise reducing processing scheme to be resonance noise. Figure 4 shows a device of the present invention number 1 in the embodiment according to tire pressure of the tire is also reducing noise upon rotation of species which resonance cross-sectional drawing, Figure 5 of the present invention number 1 in the embodiment according to tire resonance noise reducing device when the pressure of the tire is of cross-section are disclosed. The reference also 4 and 5 also, magnetic tire stop number 1 (121) number 2 on magnetic (122) is in contact with one another and by having the opposite polarity is disposed on , the number 2 magnetic (122) the upper surface of the barrier (110) also rim (R) on the upper surface substrate. After tire vibration is centrifugal force that a tire, the size of the number 1 are arranged in a magnetic (121) number 2 on magnetic (122) is essentially larger than than the size of the magnetic attractive force between number 2 (122) number 1 other end of magnetic (121) disengaged from each other. Magnetic fixed number 2 (122) of end portion, fixed to the rim (R) magnetic number 2 (122) other end of separation by barrier (110) applied with a circumferential direction of the other end of the tire tread portion of upper surface (T) by other end inner surface contact each other. The inside of tire cavity (cavity) a plurality being rotatingly thereby (cavity) inside of tire cavity resonator frequency of noise generated by the noise reducing effect resonance are dispersed generated. Case of decreasing to converge to 0 in the cylinder again and centrifugal forces, thereby magnetic number 1 (121) number 2 on magnetic (122) is disposed on the barrier between (110) is again restored the upper surface of the rim (R) 2000. Figure 6 of the present invention number 1 in the embodiment according to tire resonance noise reducing device test graph are disclosed. (Cavity Noise) inside of tire cavity resonance noise impact from high to check whether a requested device with the of road noise generated from a Pig incriminated lowering 4. ride comfort. In the case of about 200 - 250 Hz band resonates noise general if vibration occurs. Tire is more important noise resonance while toughness value that side criticism door number recognition is coming in now. 6 also reference surface, the present invention according to tire resonance noise reducing device equipped with tire has a tire of the existing method frequently occurring in about 200 - 250 Hz resonance noise RMS value reference about 4. 5dB (A) is carried, peak value about 4. 7dB noise reducing effect of (A) occurs. Of the present invention number 2 in the embodiment according to tire resonance noise reduction device then is described as follows.
