Description

Automotive seat independence sound system

Technical field

The utility model relates to vehicle sound equipment equipment technical field, especially a kind of automotive seat independence sound system.

Background technique

Existing family-sized car generally is equipped with sound power amplification system, and interior other function module is cooperated to listen to electricity to realize Platform program plays music, even answers the function of mobile phone.It is more if driver wears earphone in driving procedure Dangerous, it will affect its judgement to peripheral vehicle environment, so the sound system of most of automobile mainly includes original-pack automobile Vehicle audio.

Earphone is a kind of near field listening equipment facility, i.e. earphone diaphragm is to be close to nearly ear to listen to music, this makes sound wave The decaying of transmission in air medium is almost nil, therefore its decaying and distortion in air medium is little, so this listening Sound equipment mode is optimal.It is well known that it is to have certain damping vibration attenuation that sound wave is propagated in air, sound wave transmitting range Bigger decaying is bigger, is distorted also bigger, and high frequency sound wave is decayed faster than low-frequency sound wave, thus frequency of sound wave it is higher The loss transmitted in air is bigger.Therefore in nature, the sound wave of identical energy, always low frequency can pass a little further, and High frequency can attenuate soon.Relative to the distance (general speaker is in 5 meters from human ear) of daily listening sound equipment, although this effect It should be not it is obvious that but can be gone to measure data with sound pressure meter and can find out its difference easily.Sound is in air borne In the process, the distance of earphone diaphragm close to human ear ear-drum is close, and high frequency detail is almost without decaying, and the speaker of long distance audition is high Frequency details is then easy to attenuate during air borne, or even distorts and generate distortion.Only from fidelity for, ear Machine is to be easier to obtain the small and weak details of music replay gamut and transient state etc., and remote speaker can accomplish that this point is to be difficult , because it, which needs that higher equipment cost is spent just to obtain, restores that part being lost.

Therefore, it is desirable to automobile audio is enable to reach the replay effect for being similar to earphone, then it must be to its installation site knot Structure and arranging significantly is adjusted.

Utility model content

The purpose of this utility model is to provide a kind of automotive seat independence sound systems, pass through the head of each automotive seat Pillow is transformed, and is made the sound system that independent near field plays, can be effectively reduced what audio frequency sound was propagated in air Loss and distortion, and have apparent stereophonic effect, to greatly improve the acoustics for listening to music in automobile.

The technical solution that the utility model is proposed is such that

A kind of automotive seat independence sound system, including headrest, speaker, power amplifier and source of sound, the headrest are mounted in The upper top of motor vehicle seat back, can make upper and lower position adjusting, and the power amplifier makees signal company with speaker and source of sound respectively It connects, the headrest includes intermediate occipitalia, and the left wing and right wing part that extend at left and right sides of occipitalia and forwards, institute It states occipitalia left and right sides and further respectively has the 1st shaft and the 2nd shaft being vertically arranged, the left wing passes through the 1st shaft and occipitalia Left side is hinged, and the right wing part is hinged by the 2nd shaft and occipitalia right side, at left and right sides of the occipitalia from the 1st shaft with 2nd shaft starts to be respectively equipped with the 1st inclined-plane and the 2nd inclined-plane forward, be respectively equipped in the left and right alar part in speaker be embedded in Cavity, the angle of cut between the central axes of the loudspeaker of the speaker and the central axes of headrest are 80 °~100 ° angles.

The automobile independence sound system further includes wireless transport module, the power amplifier and wireless transport module setting In in occipitalia, signal connection is realized by wireless transport module between the source of sound and power amplifier.

The angle of cut α of 1st inclined-plane and adjacent right wing part right side is 0 °~30 ° angles, the 2nd inclined-plane and an adjacent left side The angle of cut β of alar part left side is 0 °~30 ° angles

The distance between loudspeaker in the loudspeaker and right wing part set in left wing is 400mm~500mm.

Compared with prior art, the utility model has the following beneficial effects:

Automotive seat independence sound system disclosed by the utility model passes through in the headrest left wing close to driver/head of passenger In portion and it is respectively arranged with speaker in right wing part, the angle of cut between the loudspeaker central axes in two speakers and headrest central axes is 80 °~100 ° angles, the distance between two loudspeaker fronts control between 400mm~500mm, are the equal of that will be located at The loudspeaker front of left and right side is opposite in a small range and close to the left and right ear of people, forms near field and listens to sound field effect, constitutes Approximate " open earpiece " acoustics, in this way, being not only avoided that the independent speaker of same other seats of vehicle interacted, but also can exempt Wear constriction brought by earphone, not will form more earphone " effect in head " (i.e. hearer feel music source be in people Face in front).Left and right alar part can also be passed through the 1st be vertically arranged, the 2nd shaft and occipitalia left and right side and hingedly pasted by the utility model Close, and be respectively equipped with the 1st inclined-plane and the 2nd inclined-plane forward since the 1st, the 2nd shaft in occipitalia left and right sides, these inclined-planes with The angle of cut of adjacent alar part side is 0 °~30 ° angles, thus, so that the loudspeaker of left and right alar part is made around the 1st, the 2nd shaft Small-scale horizontal direction is swung, and hoodle groove positioning mechanism can be arranged in each shaft hinge point, left and right alar part is made to exist More gear positioning in 0 °~30 ° angular ranges.In addition it is equipped with upper and lower regulating mechanism between headrest and backrest, different height can be made Short people obtains optimal listening sound field effect.

In order to obtain stereosonic spatial impression when resetting sound equipment, it is known that the sense of hearing of people is that have to distinguish sound source side The ability of position, this is the reason that people has two ears rather than an ear.Ear is grown in the two sides of head, they are not only Spatially there is distance, and obstructed by head, therefore the sound that receives of two ears might have kind of a species diversity, such as the time Lag etc. enables people to distinguish sound source in the position in space exactly according to these differences.Based on this feature, people are listening Stereo concept is proposed in terms of sound equipment.A kind of so-called stereo and solid geometry concept, is by the two of left and right side sound channel A loudspeaker and listener head constitute 3 points of distances and form an isosceles triangle, form three-dimensional sense under this specified conditions Effect is most it will be evident that being to listen to acoustic optimum position.And this stereo geometric space distance is shorter, to sound Transmission loss is smaller.The utility model be exactly according to this mechanismic design go out left and right alar part can around be vertically arranged the 1st, 2 shafts it is left, Right swing makes to obtain comfortable and shortest distance between adjacent loudspeaker and human ear.So this automotive seat independence sound equipment system It unites existing the advantages of closely being listened to close to earphone, and has apparent stereophonic effect.In this three-dimensional space listening environments Sound equipment is listened to, neither influence traffic safety can be listened to again to the optimal playback effect of three-dimensional sense, to make people in automobile audio Aspect, the capital investment without cost great number can easily obtain fine stereophonic effect and Hi-Fi stereo set.
