Then the characteristic informations such as wavelength, frequency, the amplitude of sound control oscillation drive according to the characteristic information of noise and are vibrated,
Panel issues the drop with noise same frequency, co-wavelength, same to amplitude, opposite in phase from front with the logical vibration of oscillation drive one
Noise sound, with come to noise occur destructive interference, realize reduce even be eliminated environmental noise.
The noise reduction module example scheme that above-mentioned panel and oscillation drive are formed, with the noise reduction individually formed by loudspeaker
Module scheme is compared, and in a particular application, its zone of action range size of the noise reduction sound of loudspeaker sending can not determine, is arranged more
When a loudspeaker carry out noise reduction process, loudspeaker setting position is difficult to determine.Meanwhile in practical applications, it is filled using loudspeaker as noise reduction
It sets, is also difficult to be applied in some scenes, for example, the curtain wall of building, the loudspeaker of punching installation everywhere be will form on curtain wall
It destroys, while more loudspeaker being installed in building, the style of building can be destroyed.
The noise reduction module formed by panel and oscillation drive, the mutual splicing between panel, can form a face wall,
In practical applications, denoising device can be applied to the curtain wall of building, it is ensured that while architectural style, fill by noise reduction
It sets realization reduction and even is eliminated environmental noise, facilitate the quality of working life for promoting the user in building.
Although it should be pointed out that loudspeaker formed noise reduction module there is above-mentioned the problem of pointing out, in this application,
A feasible program for being eliminated as the application noise reduction module is not represented.
To sum up, the application determines the need for noise reduction process according to the detection to environmental noise, and is determining to need to drop
It makes an uproar when handling, controls the noise reduction module and carry out noise reduction process, it can be achieved that reducing environmental noise, and then realize the work for promoting people
Make quality of life, and ensures the physical and mental health of people.
