Specific implementation mode
Preferred embodiment for the present invention, please display electronics assemblies 1 referring to Fig.1 built-in function block diagram, be
Including magnetometric sensor (Magneto Resistance Sensor, MR Sensor) 11, analog-digital converter (A/D
Converter) 12, processor 13, storage element 14 and hard disk 15.
Above-mentioned magnetometric sensor 11 is electrically connected with analog-digital converter 12.Analog-digital converter 12 and and processor
13 are electrically connected, and wherein analog-digital converter 12 is to be electrically connected with processor 13 through a serial transmission interface, the string
Row coffret can be an IC buses.Processor 13 is simultaneously electrically connected with storage element 14 and hard disk 15 respectively.
In this present embodiment, electronic device 1 is preferably a portable electronic devices, such as：Notebook computer contains firmly
The portable music player of disk includes personal digital assistant (PDA) of hard disk etc..In this present embodiment, magnetic force passes
Sensor 11 be preferably three axis magnetometric sensors, in other embodiments magnetometric sensor 11 also can be three axis magnetometric sensors or its
The magnetometric sensor of its pattern.In this present embodiment, storage element 14 is preferably a buffer, in other embodiments, storage
Unit 14 can be a buffer, non-voltile memory or volatile memory etc..In this present embodiment, it is micro- to be preferably one for hard disk 15
Type hard disk (Micro Disk Drive).
In Fig. 1, magnetometric sensor 11 is to provide its magnetic field intensity sensed, due in the present embodiment, magnetic force
Sensor 11 is three axis magnetometric sensors, therefore it can provide the magnetic field intensity of three axis (X, Y, Z) components to Analog-digital Converter
Device 12.For analog-digital converter 12 after receiving the magnetic field intensity that magnetometric sensor 11 is provided, analog-digital converter 12 will
Magnetic field intensity is converted to digital sense value and exports to processor 13.
Above-mentioned storage element 14 store plural default value (such as：First default value (P1), the second default value (P2),
Three default values (P3)).Processor 13 then judges the space displacement of electronic device 1 according to such default value with digital sense value,
If electronic device in a preset time (such as：1 second) one space displacement of interior generation (translate or fall) (0.75 meter), processor
Control signal can be sent out to control 15 starting protection mechanism of hard disk.In relation to the relevant treatment how processor 13 is judged, respect
Please refer to following the description.
Above-mentioned processor 13 can be handled the digital sense value of one of them or two axis components, or sequentially/
It is handled with to the digital sense value to three axis components.Following situations that a wherein axis component will be handled with processor 13
To illustrate.After processor 13 receives digital sense value (S1), processor 13 is to digital sensing value (S1) and the first default value
(P1) it is handled, to find out a difference (B1).Then processor 13 is again by digital sense value (S1) and the first default value (P1)
Difference (B1) compared with the second default value (P2) and third default value (P3).
If difference (B1) is less than the second default value (P2), represents electronic device 1 and be likely to be at normal space movement (example
Such as：Portable apparatus is carried by a user walking), electronic device 1 also may be stationary state, that is, electronic device 1 may
It is placed in without being moved on a desk, as shown in Figure 2 a.At this point, processor 13 still maintains its normal operating, and it is hard
It, will not be impacted if disk 15 is being operated at this time.Such as：In Fig. 3 a, hard disk 15 is a hard disk, and it includes disk to be
Piece 151, magnetic head 152 and moving arm 153, wherein magnetic head 152 are mounted on one end of moving arm 153.Due to hard disk at this time
Carry out data access, thus moving arm 153 can by hard disk controlling chip controls, be moved to the appropriate location on disc 151 into
Row data access.For processor 13, since digital sense value (S1) and the difference (B1) of the first default value (P1) are less than
Second default value (P2), so processor 13 still maintains its normal operating, and hard disk will continue its data access.
If difference (B1) is more than the second default value (P2), and difference (B1) is less than third default value (P3), then represents electronics
There may be violent space displacements for device 1, such as：Electronic device 1 may be fallen from a desktop toward floor, as shown in Figure 2 b.
At this point, processor 13 generates a control signal, and the control signal is transmitted to hard disk 15 by processor 13, with starting protection machine
System.Such as：In Fig. 3 b, hard disk may carry out data access at this time, so moving arm 156 is moved on disc 154
Appropriate location, to carry out data access.For processor 13, since difference (B1) is more than the second default value (P2), and it is poor
It is worth (B1) and is less than third default value (P3), so processor 13 generates control signal, and is passed to hard disk so that the control of hard disk
Chip controls moving arm 156 processed leaves the region of disc 154, for carrying out 155 return of magnetic head, to avoid electronic device 1 because violent
Space displacement and the impact force that generates causes magnetic head 155 mutually to be collided with disc 154, in turn result in data and move and lose or hard disk generates
Failure.
If difference (B1) is more than third default value (P3), represents electronic device 1 and may be close to magnetisable material, so that
The magnetic field intensity that magnetometric sensor 11 is sensed is excessive.For such situation, processor 13 will maintain its normal operating without
Start anti-vibration protected mechanism.
It is certainly, above-mentioned that about processor 13, how the magnetic field intensity sensed through magnetometric sensor 11 judges that electronics fills
It sets whether 1 have strenuous exercise, is merely a preferred embodiment.In other embodiments, storage element 14 can also store a pair
According to table, which has a plurality of typical values, each typical value represent electronic device 1 various motion states (such as：It is quiet
Only, normal space displacement or violent space displacement etc.) under desired quantity.Therefore, processor 13 is receiving digital sense
After value, it is that the numerical digit sensing value can be compared the table of comparisons, to find out the immediate typical value of digital sense value, then handles
The typical value that device 13 is found out according to it again starts anti-vibration protected mechanism to maintain its normal operating or control hard disk 15.
It can be seen from the above explanation whether the present invention is in violent space using magnetometric sensor come detection electronic installation
Displacement, if so, control signal first is provided through processor, so that hard disk first can actively carry out anti-vibration protected mechanism,
The chance of hard disk failure due to impact force is reduced whereby, and can be increased hard disk stability, be prevented Missing data and without expending
A large amount of inner spaces are mechanical shockproof to provide.
It is only for the sake of illustration for above-described embodiment, and the interest field that the present invention is advocated certainly should be with right
It is required that protection domain described in subject to, not just the above examples.
