In a kind of possible embodiment, the revolving speed of system fan can be adjusted by stepping revolving speed.Optionally, right
For system fan, stepping revolving speed when adjustment can be more than or equal to the 1% of system fan maximum speed, such as system fan
Maximum speed be 3000 revs/min, then stepping revolving speed can be set to 30 revs/min, or may be set to be 120 revs/min,
Etc..Stepping revolving speed can be preset, or can also when the revolving speed of system fan need to be adjusted according to system fan most
The sensitive frequency of hard disk in high revolving speed and/or electronic equipment is arranged, and illustrates separately below.
The case where presetting stepping revolving speed.For example, electronic equipment includes three hard disks, the model of these three hard disks is distinguished
It is 1,2 and 3, electronic equipment further includes a system fan, can be these three Hard disk heat radiations.Such as the hard disk of model 1
The frequency point that sensitive frequency includes is 10Hz, and including frequency band be [20-30] Hz, the sensitive frequency of the hard disk of model 2 includes
Frequency point be 12Hz, the frequency band that the sensitive frequency of the hard disk of model 3 includes be [40-50] Hz, the maximum speed of system fan
For example, 3000 revs/min.If the current revolving speed of the system fan obtained is 600 revs/min, the current vibration of system fan
Frequency is 10Hz, consistent with the sensitive frequency 10Hz of the hard disk of model 1, for example, stepping revolving speed be it is preset, for example,
30 revs/min, the current revolving speed of system fan is adjusted according to stepping revolving speed, for example the revolving speed of system fan can be adjusted to system
The sum of the current revolving speed of fan and stepping revolving speed, then the revolving speed of system fan is 630 revs/min after adjustment, corresponding frequency is
10.5Hz, it is all inconsistent with the sensitive frequency of the hard disk of the sensitive frequency and model 2 of the hard disk of model 1, then can be true
This fixed adjustment is completed, and system fan can be according to rotary speed working adjusted.And for example preset stepping revolving speed be 120 turns/
Point, then the revolving speed of system fan is adjusted to the sum of the current revolving speed of system fan and stepping revolving speed, system fan after adjustment
Revolving speed be 720 revs/min, corresponding frequency is 12Hz, consistent with the sensitive frequency of the hard disk of model 2, then needing to continue
The current revolving speed of adjustment system fan can continue for the revolving speed of system fan to be adjusted to the current revolving speed of system fan and stepping
The sum of revolving speed is adjusted to 840 revs/min, judge again later system fan vibration frequency whether the sensitivity with these hard disks
Frequency is consistent, to avoid the sensitive frequency of all hard disks as far as possible.Optionally, as long as the sensitive frequency and electronic equipment of system fan
In need protection any one hard disk any one sensitive frequency it is consistent, be considered as the vibration frequency and hard disk of system fan
Sensitive frequency it is consistent, it is necessary to adjust the revolving speed of system fan.
When presetting stepping revolving speed, the size and hard disk itself of stepping revolving speed setting have relationship.If hard disk is quick
It is more close to feel frequency, then the stepping revolving speed being arranged can be larger, to avoid under the premise of reducing and adjusting number as far as possible
All sensitive frequencies.For example, the hard disk of model 1 sensitive frequency include frequency point be 10Hz, and including frequency band be
[10.5-11] Hz, the frequency point that the sensitive frequency of the hard disk of model 2 includes are 11.5Hz, the sensitive frequency of the hard disk of model 2
Including frequency band be [12-13] Hz in the case where, it is right when system fan and hard disk fan maximum speed are 3000 revs/min
The setting of stepping revolving speed can be different.
When the revolving speed of system fan need to be adjusted according to the hard disk in the maximum speed and/or electronic equipment of system fan
Sensitive frequency is come the case where being arranged stepping revolving speed.For example, electronic equipment includes three hard disks, the model of these three hard disks is respectively
1,2 and 3, electronic equipment further includes a system fan, can be these three Hard disk heat radiations.Such as the hard disk of model 1 is quick
The frequency point that sense frequency includes is 10Hz, and including frequency band be [20-30] Hz, the sensitive frequency of the hard disk of model 2 includes
Frequency point is 12Hz, and the frequency band that the sensitive frequency of the hard disk of model 3 includes is [40-50] Hz, the maximum speed example of system fan
For example 3000 revs/min.For example, the current revolving speed of system fan obtained is 600 revs/min, then the vibration that system fan is current
Frequency is 10Hz, consistent with the sensitive frequency 10Hz of the hard disk of model 1, in order to reduce the current revolving speed of adjustment system fan
Stepping revolving speed can be arranged in number according to the sensitive frequency of the hard disk in the maximum speed of system fan and/or electronic equipment,
The revolving speed of system fan adjusted is allowed to avoid 12Hz, [20-30] Hz and [40-50] Hz these sensitive frequencies simultaneously,
For example stepping revolving speed can be set to 300 revs/min, then the revolving speed of system fan is 900 revs/min after adjustment, corresponding frequency
Rate is 15Hz, all inconsistent with the sensitive frequency of 3 hard disks, then can determine that this adjustment is completed, system fan can be by
According to rotary speed working adjusted, in this way, required adjustment number is less, and the sensitive frequency of all hard disks can be avoided.
Optionally, the current revolving speed of adjustment hard disk fan, can there is different adjustment modes, for example, can be by default
Stepping revolving speed adjustment, can also be when the revolving speed of fan need to be adjusted according in the maximum speed of fan and/or electronic equipment
The case where sensitive frequency of hard disk is adjusted stepping revolving speed is arranged, and adjustment mode can refer to system fan, repeats no more.
Certainly, the above only example, for the quantity and sensitive frequency of the hard disk for including in electronic equipment, and including
The quantity etc. of system fan, the embodiment of the present invention is with no restriction.
Optionally, either system fan or hard disk fan, if the current vibration frequency of the fan obtained and sensitive frequency
Rate is inconsistent, then fan can be enabled to keep current revolving speed.When the current vibration frequency of fan and sensitive frequency are inconsistent, firmly
Disk will not generate resonance, and vibratory output is smaller, there is no need to adjust the revolving speed of fan, fan be enabled to keep current revolving speed.
