Description
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
It is difficult to the inexpensive listening music effect gone to reach as earphone for existing automobile audio, while wearing ear
Machine is not suitable for driver's use again, and the utility model provides a kind of automotive seat independence sound system, is directed to each vapour
The headrest of vehicle seats is transformed, and is made the sound system that independent near field plays, can be effectively reduced audio frequency sound in sky
The loss and distortion propagated in gas, and have apparent stereophonic effect, music is listened in automobile to greatly improve
Acoustics.
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
State the cavity being respectively equipped in left and right alar part for being embedded in speaker, the central axes of the loudspeaker of the speaker and the axis of headrest
The angle of cut between line is 60 °~hexagonal angle degree.
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 occipitalia upper back is equipped with and is parallel to occipital view and horizontally disposed shaft, the left wing and right flank part
It is not hinged with the left and right both ends of the shaft.
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
60 °~hexagonal angle degree, 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 be also hingedly bonded by horizontal rotating shaft with occipitalia left and right side by the utility model, be made left and right
The loudspeaker of alar part can turn around axis and make small-scale upper and lower swing, since leather coefficient of friction is big, therefore can arbitrarily position.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 and preferably listen to 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.So this automotive seat independence sound system existing the advantages of closely being listened to close to earphone, and have obvious
Stereophonic effect.Sound equipment is listened in this three-dimensional space listening environments, neither influence traffic safety can be listened to again to solid
Feel optimal playback effect, to make people in terms of automobile audio, can easily be obtained without the capital investment for spending great number
Obtain fine stereophonic effect and Hi-Fi stereo set.
