Description
Technical Field
The utility model belongs to car electrical equipment field, concretely relates to car noise reduction system.
Background
Noise under public road environment reaches more than 80 minutes at present, and the people is in under this environment and can appear the symptom of dizziness tinnitus more than the hour, and even the person probably vomits, so the harm of noise to people is very big, and the noise source under public road environment is many, for example: vehicle self noise, wind dryness, tire noise, noise generated by other vehicles, urban environment noise, natural noise and the like. Therefore, noise can not be reduced one by one aiming at single noise, the existing automobile has the technical scheme aiming at the noise reduction of the engine, but the actual effect is not obvious, and only the noise reduction aiming at one early cause is realized. Various noises caused by the above-mentioned factors have a great influence on the driver and the passenger in the vehicle.
Disclosure of Invention
The utility model discloses an overcome the above-mentioned problem that prior art exists, provide an automobile noise reduction system.
The utility model discloses an adopt following technical scheme to realize:
a noise reduction system for an automobile is used for reducing noise in the automobile, four microphones and two speakers are arranged on a headrest of a driver seat in the automobile, wherein a left front microphone is arranged on the left side of the front surface of the headrest of the driver seat, a right front microphone is arranged on the right side of the front surface of the headrest of the driver seat, a left rear microphone is arranged on the left side of the rear surface of the headrest of the driver seat, a right rear microphone is arranged on the right side of the rear surface of the headrest of the driver seat, a left headrest speaker is arranged on the left side surface of the headrest of the driver seat, a right headrest speaker is arranged on the right side surface of the headrest of the driver seat, a noise reduction processor is arranged in the automobile, the left front microphone, the right front microphone, the left and right microphones, the right rear microphone, the left headrest speaker, the right headrest speaker, the left headrest speaker and the right headrest speaker are all connected with the.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides a pair of car noise reduction system arranges a plurality of microphones on driver's headrest for the noise that personnel can hear in the collection car, the treater of making an uproar that falls can carry out analysis and calculation to the noise of gathering, calculates the audio sound wave reverse with the noise sound wave, and the sound wave of making an uproar falls is broadcast out to rethread headrest speaker, falls the sound wave of making an uproar and offsets with the noise sound wave, reaches the effect of making an uproar of falling initiatively.
