Description
Technical field
The present invention relates to vehicle sound equipment equipment technical field, especially a kind of automotive seat independence sound system.
Background technology
Existing family-sized car generally is equipped with sound power amplification system, other interior function modules is coordinated 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, its judgement to peripheral vehicle environment can be influenced, so the sound system of most of automobile includes mainly 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, and distortion is 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.For only from fidelity, 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 needs to spend higher equipment cost just to obtain that part for being lost of reduction.
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.
Invention content
The purpose of the present invention is to provide a kind of automotive seat independence sound system, by the headrest of each automotive seat into
Row transformation makes the sound system that independent near field plays, can be effectively reduced the loss that audio frequency sound is propagated in air
And distortion, and have apparent stereophonic effect, to greatly improve the acoustics for listening to music in automobile.
Technical solution proposed by the invention is such：
A kind of automotive seat independence sound system, including headrest, speaker, power amplifier and source of sound, the headrest are mounted in automobile
The upper top of backrest can make upper and lower position adjusting, and the power amplifier is connect with speaker and source of sound as signal respectively, institute
The occipitalia that headrest includes intermediate is stated, and positioned at the left wing and right wing part occipitalia the left and right sides and extended forwards, the pillow
Portion's left and right sides further respectively have the 1st shaft and the 2nd shaft being vertically arranged, and the left wing passes through the 1st shaft and occipitalia left side
Face is hinged, and the right wing part is hinged by the 2nd shaft and occipitalia right side, from the 1st shaft and the 2nd turn at left and right sides of the occipitalia
Axis starts to be respectively equipped with the 1st inclined-plane and the 2nd inclined-plane forward, and the cavity for being embedded in speaker is respectively equipped in the left and right alar part,
The angle of cut between the central axes of the loud speaker of the speaker and the central axes of headrest is 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 loud speaker in the loud speaker and right wing part set in left wing is 400mm~500mm.
Compared with prior art, the present invention has following remarkable result：
Automotive seat independence sound system disclosed by the invention passes through in the headrest left wing close to driver/head of passenger and right
Speaker is respectively arranged in alar part, the angle of cut between loud speaker central axes in two speakers and headrest central axes is 80 °~
100 ° of angles, the distance between two loud speaker fronts control between 400mm~500mm, are the equal of that will be located at left and right side
Loud speaker front a small range against and close to the left and right ear of people, form near field and listen to sound field effect, constitute approximation and " opens
Put formula earphone " acoustics, in this way, being not only avoided that the independent speaker of same other seats of vehicle interacted, but also it can exempt and wear earphone
Caused constriction will not more be formed " effect in head " of earphone（I.e. hearer feel music source be people in front
Face）.The present invention can also by left and right alar part by be vertically arranged the 1st, the 2nd shaft is hingedly bonded with occipitalia left and right side, and resting the head on
Portion's left and right sides are respectively equipped with forward the 1st inclined-plane and the 2nd inclined-plane since the 1st, the 2nd shaft, these inclined-planes and the adjacent wing
The angle of cut of portion side is 0 °~30 ° angles, to enable the loud speaker of left and right alar part to make around the 1st, the 2nd shaft small-scale
Horizontal direction is swung, and hoodle groove detent mechanism can be arranged in each shaft hinge point, be made left and right alar part at 0 °~30 °
More gear positioning in angular range.In addition it is equipped with upper and lower regulating mechanism between headrest and backrest, the people of different height can be made to obtain
Obtain listening sound field effect most preferably.
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 both 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's differentiation 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 loud speaker constitutes 3 points of distances with listener head and forms an isosceles triangle, and three-dimensional sense is formed 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 present invention be exactly according to this mechanismic design go out left and right alar part can around be vertically arranged the 1st, the left and right pendulum of 2 shafts
It is dynamic to make to obtain comfortable and shortest distance between adjacent loud speaker and human ear.So this automotive seat independence sound system was both
There is the advantages of closely being listened to close to earphone, and has apparent stereophonic effect.It is listened in this three dimensions listening environments
Sound equipment, neither influencing traffic safety can listen to again to the best playback effect of three-dimensional sense, to make people in terms of automobile audio,
It need not spend the fund input of great number that can easily obtain fine stereophonic effect and Hi-Fi stereo set.
