Noise wave W1 is a sound wave, is physically belonging to dilatational wave, i.e. medium motion direction is parallel with wave direction of travel
Longitudinal wave, the action of weakening in dilatational wave may bad understanding, therefore audio treatment unit 13 can be parsed noise wave W1's
Behavior is considered as the density degree according to medium and noise wave W1 is converted into a corresponding noise waveform data (can be considered will make an uproar
The longitudinal wave of sound wave W1 is converted into a corresponding shear wave according to Media density), that is, there is noise waveform and frequency noise.And foundation
Above-mentioned noise waveform data generate a corresponding noise reduction Wave data, wherein the noise reduction frequency of noise reduction Wave data and noise frequency
Rate is identical, and noise reduction waveform is opposite up and down with noise waveform.
Noise reduction wave generates after unit 14 receives noise reduction Wave data and modulates a noise reduction wave W2, and is passed by speaker unit 15
Send out noise reduction wave W2.According to the superposition principle of wave, the noise waveform of the noise reduction waveform and noise wave W1 of the noise reduction wave W2 sent out
Because opposite up and down so that noise reduction wave W2 and the waveform of the noise waveform data after noise wave W1 superpositions tend towards stability, substantive upper table
Showing that medium density degree is close, noise reduction wave W2 weakens noise wave W1, and the effect of reach noise reduction.
Preferably, one straight line of waveform formation of noise reduction wave W2 and the noise waveform data after noise wave W1 superpositions, i.e. waveform
Without concussion up and down, substantially indicate that medium density degree is identical, noise reduction wave W2 can weaken noise wave W1 completely, reach complete
The effect of eliminating noise.
Please refer to Fig. 4 and Fig. 5, the master with decrease of noise functions that Fig. 4 is provided for display the utility model second embodiment
The sectional perspective schematic diagram of machine plate；The host with decrease of noise functions that Fig. 5 is provided for display the utility model second embodiment
The functional block diagram of plate.As shown, to provide a kind of motherboard with decrease of noise functions (following for the utility model second embodiment
Referred to as " motherboard ") 1a includes that a motherboard ontology 11a, a radio reception are raised one's voice module 12a, an audio treatment unit 13 and a noise reduction
Wave generates unit 14, wherein a radio reception raises one's voice module 12a also comprising an a radio unit 121a and speaker unit 122a.In addition,
Audio treatment unit 13 generates unit 14 with noise reduction wave and is identical with the first embodiment, therefore does not repeat herein.
One fan 3 generates a noise wave W1a in the running, and the raise one's voice radio unit 121a of module 12a of radio reception is received and made an uproar
Sound wave W1a, and noise wave W1a is sent to audio treatment unit 13.Audio treatment unit 13 receives and parses through noise wave W1a,
To obtain the noise waveform data for corresponding to noise wave W1a, and a noise reduction Wave data is generated according to noise waveform data.Disappear
Sound wave generates unit 14 and is electrically connected audio treatment unit 13, after receiving noise reduction Wave data, modulates one and makes an uproar to weaken
The noise reduction wave W2a of sound wave W1a.Wherein, noise waveform data and noise reduction Wave data and the noise mentioned in first embodiment
Wave data is identical as noise reduction Wave data, and the mode that noise reduction wave W2a weakens noise wave W1a also disappears with mentioned by first embodiment
The mode that sound wave W2 weakens noise wave W1 is identical, therefore does not repeat herein.
First embodiment is different with second embodiment to be in in the first embodiment, radio unit 12 and speaker unit
Be arranged to 15 pairs of property and be arranged in pairs region S one, be arranged in pairs in the S of region, radio unit 12 and speaker unit 15 away from
It significantly fails from noise wave W1 can't be caused so that noise wave W1 is transmitted to the waveform of radio unit 12 and speaker unit 15
It is almost identical.However, in practice, radio unit 12 is at a distance from speaker unit 15, the frequency and sound of noise wave W1 and W1a
The computer processing time of frequency processing unit 13 can all cause phase difference, the especially distance of radio unit 12 and speaker unit 15
Even more directly phase difference is impacted, and can phase difference be an important factor for weakening noise wave W1 and W1a.It is real second
It applies in example, radio unit 121a and speaker unit 122a modularizations form the radio reception module 12a that raises one's voice and therefore receive noise wave
W1a and generate noise reduction wave W2a are all that radio reception is raised one's voice module 12a, and then is solved in first embodiment because receiving noise wave W1
Radio unit 12 and the distance for the speaker unit 15 for sending noise reduction wave W2 lead to the problem of phase difference, but also second
In embodiment radio reception raise one's voice the noise reduction wave W2a that module 12a sends out weaken the effect of noise wave W1a can be preferable.
In first embodiment and second embodiment, noise wave W1 and W1a is that fan 3 is produced when operating, but is not limited to
Produced by fan 3, it is also possible to for other electronic components (such as：Electronic component 4 and 4a) caused by electromagnetic interference sound.This
Outside, it is audible to be also not necessarily limited to the mankind for noise wave, it is also possible to which the mankind can't hear but can be transported to computer internal electron spare part
Make the noise impacted.In addition, in second embodiment, radio unit 121a forms a radio reception with speaker unit 122a modularizations
Module of raising one's voice 12a achievees the effect that weakening noise wave W1a can preferably, but be not excluded in the first embodiment, according to noise wave
The frequency of W1 and W1a and the computer processing time of audio treatment unit 13 go setting radio unit 12 and speaker unit 15 away from
From can also achieve the effect that weakening noise wave W1 identical with second embodiment.
In practice, produced by noise wave is generally inside electronic device, but it is not excluded for as caused by external environment
Noise wave.
In conclusion due to a kind of electronic device and its motherboard packet with decrease of noise functions provided by the utility model
Containing a motherboard and a device body.Motherboard includes a motherboard ontology, at least a radio unit, an audio frequency process list
Member, a noise reduction wave generate unit and an at least speaker unit.Radio unit receives a noise wave, and audio treatment unit receives simultaneously
Parsing noise wave generates a noise reduction waveform number to generate the noise waveform data of corresponding noise wave according to noise waveform data
According to.Noise reduction wave generates unit reception noise reduction Wave data and modulates a noise reduction wave, and passes through an above-mentioned at least speaker unit and transmit
Go out noise reduction wave, to weaken noise wave.
Compared to the prior art, by covering very thin flannelette to shade in flabellum and outline border or absorb noise wave, or
It is by turning down operating efficiency with rotation speed of the fan to reduce the generation of noise.It is provided by the utility model a kind of with noise reduction work(
Can electronic device and its motherboard, because an at least radio unit, an audio treatment unit, a noise reduction wave generate unit and at least
