Abstract
The present case is an active noise reduction headrest, includes: the headrest casing, fixed arranging in the inside first speaker of headrest casing, second speakers, the first sensor, the second sensor, the controller integrated circuit board, and fill in the inside headrest core except that above -mentioned component position of headrest casing, wherein, first speaker, second speakers are located respectively the left and right sides of headrest casing is close to two ear departments, first sensor, second sensor are located respectively both ends about the headrest casing, wherein the controller integrated circuit board is used for the signal acquisition of first speaker, second speakers, first sensor, second sensor to be used for falling and make an uproar in order to control mode that first speaker, second speakers sent the opposition noise.
Description
Technical field
This utility model relates to headrest, particularly relates to a kind of active noise reduction headrest.
Background technology
Automotive headrest is a kind of driver comfort configuration articles for use and security protection articles for use.Automotive headrest belongs in country's vehicle complete vehicle forcible authentication detection project, has strict regulation from material, intensity, energy absorption capacity, position and size etc..In current national standard, simply car front seat configuration automotive headrest is specified, and whether rear row seat is configured automotive headrest and do not have mandatory provision.The material of automotive headrest must be comfortable.Pliability and permeability are good, and it is tired effectively to alleviate the cervical vertebra in driving procedure.Ergonomic designs to be met, the most docile with human body on radian.Headrest on the market does not has a kind of its anti-noise product being specifically designed for high noise environments and design.Earphone typically covers in ears, is especially suitable for the king-sized working environment of noise, and such as Generators, drilling, but be not used to automobile in road surface, one is to affect audition, and two is that itself is containing a certain amount of low frequency noise, such as " sound of the wind " in earmuff.Therefore, its noise of automotive headrest general tree the most on the market is acted upon.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of active noise reduction headrest efficiently going noise, simple in construction.
For achieving the above object, this utility model is achieved through the following technical solutions:
A kind of active noise reduction headrest, including: headrest housing 1, fixing the first speaker 2 being placed in described headrest enclosure interior, second speaker 3, first sensor 4, second sensor 5, controller board 6, and it is filled in described headrest enclosure interior headrest core 7 in addition to above-mentioned component locations, wherein, described first speaker, second speaker lays respectively at the left and right sides of described headrest housing at two ears, described first sensor, second sensor lays respectively at the left and right of described headrest housing, described controller board is positioned in described headrest core inner centre position, wherein said controller board is used for described first speaker, second speaker, first sensor, the signals collecting of the second sensor, and to control the first speaker, second speaker sends the mode of anti-phase noise for noise reduction.
Preferably, described active noise reduction headrest, described controller board comprises can drive described first speaker, the power amplifier module of the second speaker.
Preferably, described active noise reduction headrest, wherein, between described first speaker, the second speaker, it is additionally provided with guide duct.
Preferably, described active noise reduction headrest, wherein, described headrest core includes bamboo charcoal.
The beneficial effects of the utility model: before and after the first speaker, the second speaker are respectively arranged on headrest housing by this case, first sensor, the second sensor are respectively arranged on the left and right of headrest housing, controller board is arranged in described headrest core inner centre position, while the noise that making rests the head on not only considerably reduces air purifier, volume, weight the most significantly increase, the design of this structure makes headrest not have foreign body sensation, there is not potential safety hazard.
Accompanying drawing explanation
Fig. 1 is the structural representation of the active noise reduction headrest described in this utility model one embodiment.
Wherein, 1-rests the head on housing, 2-the first speaker, 3-the second speaker, 4-first sensor, 5-the second sensor, 6-controller board, and 7-rests the head on core.
