Description
Technical field
The utility model relates to a kind of smart home components, and in particular to a kind of smart home denoising device belongs to intelligence
Household technical field.
Background technique
In daily life, we can be influenced all the time by noise；Such as automobile engine and row in civil field
The noise of feed channel, the brings noise such as ventilation shaft, transformer, compressor in industrial circle；Especially room internal fan, sky
Adjust etc. electrical equipments generate noise on human work, sleep have serious influence, high-intensitive noise hazard people
Body, make one to feel fatigue, generate negative feeling, or even cause disease.Requirement due to people to quality of life is increasingly
Height is especially required to reduce the noise under certain particular surroundings, therefore is particularly important to the control of noise；Fan noise exists
It is all a kind of more universal noise source in daily life and industrial production, the effect of fan is that generating enough pressure makes to need
The gas wanted can pass through, so generally fan noise is made of rotational noise and wadding flow noise two parts；Due to this portion
Point noise is at low-frequency range, therefore traditional passive noise control is wanted to reach good noise reduction effect and is difficult；Thus
Chinese Patent Application No.: 201620789851.3, a kind of smart home denoising device is disclosed, includes to be acquired with primary noise
The connected DSP processing unit of unit, DSP processing unit are connected with secondary noise output unit, residual noise acquisition unit respectively；
The noise that primary noise source generates is propagated in space forms sound field；Reference sensor acquisition in primary noise acquisition unit is just
Pre-amplification circuit is sent into after grade noise signal and carries out signal amplification, and amplified signal passes sequentially through frequency overlapped-resistable filter and AD
Analog signal is converted digital signal by conversion module, send to DSP processing unit and carries out adaptive noise cancellation processing；After processing
Signal pass sequentially through D/A conversion module, smoothing filter and power amplifier amplification after drive the speaker issue and primary noise
Amplitude is identical, opposite in phase noise；Residual noise signal after the acquisition counteracting of residual noise acquisition unit, by residue signal
Amplify, be converted into digital signal after send to DSP processing unit processes；Have the characteristics that denoising effect is good, structure is simple；But its nothing
Method is removed dryness to the noise that outside enters and noise reduction, and it is inflexible to remove dryness mounting location.
