Abstract
The utility model relates to a left and right loudspeaker decoration assembly for a vehicle, which is arranged on the front-lower portion of the windshields of the left and the right vehicle front doors. An outer cover is shaped in triangle with a circular arc sideline and a circular arc surface. A pressing frame is arranged on the surface of three edges of the triangle cover. A sound box cloth is arranged on the surface of the triangle outer cover and a loudspeaker is arranged inside the outer cover. The utility model has the advantages of saving room inside the vehicle, good sound box effect, beautiful appearance and practical usage, which has the same sound effect level with a driver, maximally solves the problem of high-frequency indication and provides the driver with the best sound effect. The loudspeaker is assembled firmly.
Description
Technical field
The utility model belongs to, and particularly a kind of car left and right sides loud speaker is decorated assembly.
Background technology
China's car industry has at present welcome a golden period, and the product of various class in bazaar sale on the market, and the middle and high class product of main flow for a long time by internationally renowned brand in occupation of.Under this background, belong to Chinese's oneself medium-to-high grade car fully as the elder brother the First Automobile Group a intellectual property of resolution research and development of Domestic Automotive Industry.The position that the car of China's production is in the past installed high pitch loudspeaker generally all is chosen on the front panel, design can make that thereby front panel is roomy to occupy more interior space volume like this, this design concept has not met modern's aesthetic conceptions, and saying from driving audiovisual aspect neither optimal selection.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of car left and right sides loud speaker to decorate assembly.
The technical solution of the utility model is:
A kind of car left and right sides loud speaker is decorated assembly, it is characterized in that: it is that the left and right sides loud speaker that is contained in Qianmen, car left and right sides windshield forward lower comer is decorated assembly, its outer cover is circular arc sideline and cambered surface triangle outer cover, there is press box on surface, triangle outer cover three limit, triangle outer cover surface is a Music centre loudspeaker cloth, is loud speaker in the outer cover.
On the windshield doorframe of Qianmen, the car left and right sides, reference column and jump ring are being arranged.
The utility model effect is:
Save interior space, acoustics is good, and is both artistic and practical.
The design feature of outer Decorative Cover installation site:
From acoustic angle, the high frequency sound wave wavelength is shorter, diffraction is poor, directive property is very strong, that is to say between high frequency sound wave and the people's ear and preferably be on the same horizontal line, and do not have barrier between the two, audio visual effect the best under such condition is if the unreasonable auditory effect in high-frequency sound source position can non-constant.By my designer of company repetition test finally to the designer of the First Automobile Group motion: loud speaker is installed on the position of automobile front door outside rear-view mirror interior trim cover, because herein with driver's audiovisual point substantially on a horizontal line, overcome high frequency directive property problem to greatest extent, made the driver and passenger obtain best auditory effect.(seeing accompanying drawing 1)
2) design feature of outer Decorative Cover:
How loud speaker is installed in the outer Decorative Cover, will guarantees that also the reliability of installing is the big difficult point in my company's design.Proof increases a loud speaker back cover design by experiment, and after loud speaker was encased with the loud speaker back cover, the method that is connected with outer Decorative Cover with tapping screw had well solved the problem of loud speaker installation reliability.(seeing accompanying drawing 2)
Loud speaker is installed in the outer Decorative Cover, outwards sounds by the aperture on the outer Decorative Cover, the design of angle of apertures is related to the directive property problem of high pitch loudspeaker again.Fit actual experiment by three-dimensional car internal mold, finally determined the angle of apertures problem.

Embodiment
A kind of as shown in the figure car left and right sides loud speaker is decorated assembly, it is characterized in that: it is that the left and right sides loud speaker that is contained in Qianmen, car left and right sides windshield forward lower comer is decorated assembly, its outer cover is circular arc sideline and cambered surface triangle outer cover, there is press box on surface, triangle outer cover three limit, triangle outer cover surface is a Music centre loudspeaker cloth, is loud speaker in the outer cover.
On the windshield doorframe of Qianmen, the car left and right sides, reference column and jump ring are being arranged.This product is the product that aims at the supporting research and development of Changchun First Auto Work Car Co., Ltd Pentium series car.
Concrete improvement explanation:
How outer Decorative Cover installed with car door relate to the designed parts of my company and other parts carry out rational connectivity problem.Through my designer of company to the designer of the First Automobile Group suggestion, determine to adopt jump ring add the location by the dress mode.On Decorative Cover, design 2 by the square column of the spring that is installed and the cylinder of 1 location usefulness, simultaneously in car door 3 holes of position upper punch by the dress Decorative Cover, as long as the reference column on the Decorative Cover and jump ring are found accurately the position in hole on the car door, firmly press-fiting the decorations cover outer surface just can be by installing to the position during installation.This kind mounting means has passed through the experimental verification of a vapour car company.(seeing accompanying drawing 2)
Outer Decorative Cover is installed on the car door, mean that outer Decorative Cover becomes inside gadget, this just relates to the coordinating and unifying of outer Decorative Cover and car load interior trim and attractive in appearance, and the several schemes by I designer of company offers a vapour aspect finally are fixed to present supply of material state to product shape.Be to satisfy indoor environment and the requirement of strength of material performance requirement, car that a vapour aspect proposes this part, we repeatedly prove and the heat-proof ABS material is adopted in analog computation decision such as intensity, and this material is the experimental verification by a vapour car company.(seeing accompanying drawing 3)
The design feature of tweeter: the performance requirement of tweeter and the installation requirement of loud speaker are had following characteristics according to a vapour:
One vapour has the medium-to-high grade car of independent intellectual property right and own brand, and the loudspeaker sound effect will be equal to daily output Mazda product.Because loud speaker will be installed in the outer Decorative Cover, determines the external form of loud speaker according to the shape that designs outer Decorative Cover.Final design have external form small and exquisite, attractive in appearance, work good with outer Decorative Cover and require sound pressure level higher, but because the restricted quarters such as external form are smaller, its sound pressure level requirement is than higher, the amplitude of its loud speaker is relatively large.
According to the performance requirement of a vapour aspect acoustic performance is designed tweeter, the user has relatively high expectations to the sensitivity of product, general polyester fiber diaphragm is difficult to meet the demands, and makes diaphragm through the PEN material of the final selection of trial-production du pont company production repeatedly and guarantees that its high pitch range is bright, clear.On the structure of loud speaker, we take into full account, and the space is little, power is big and problem such as sound film amplitude limit solves from the cooperation location of sound film and front shroud, and adopts good engineering plastics to solve heat-resisting problem.We adopt special (4229 model magnet steel) magnetic circuit system as its loud speaker in order to guarantee its actuating force, have so not only improved the magnetic energy level but also have reduced volume and weight.
