Description
Technical field
The present invention relates to a kind of sound equipment, specifically a kind of integrated digital car audio system.
Background technology
It is a special sound field environment inside car, not only interior spatial volume finite sum audition area is relatively
Little, and there are two kinds of different acoustic characteristics in the same space：Compartment top is by roof, front-and-back stop glass and both sides car door
Glass constitutes a strong reflection sound field space, and the flexible material such as the seat of compartment bottom, carpet, patch makes a large amount of sound wave quilts
Absorb, because seat not only can stop the propagation of sound wave, and its irregular geometric jacquard patterning unit surface also can change the direction shape of sound wave
Become diffusion, thus constituting a complex sound field space not only having absorbed but also having reflected diffusion.
At present, the speaker of most of vehicle audios is arranged in car door and surveys bottom, is limited with cost by body construction, many
Loudspeaker are simply arranged on car door or body inner side by the independent case body not matched inside number auto loud hailer, using its folder
Layer cavity is as casing.Because car door material is plastics and iron sheet, rigidity is low, damping error, internal volume are either large or small, geometric form for it
Shape mismatches, the sound-absorption coefficient factor such as not, directly affects the normal performance of speaker electroacoustic performance.
Traditional speaker Installation Modes, can replay and listen to effect to in-car music and bring multiple negative effect.When raising
During sound device playback, the cavity as casing can produce case sound and standing wave sound because of its structure and above-mentioned physical characteristics, also can simultaneously
Cause the resonance installing panel to produce noise, so that original music tonequality is contaminated by sound, cause the distortion factor to increase.
The radiation characteristic of speaker is：Frequency response the most flat equilibrium when axial 0 °, with the increasing listening to angle, frequency response
Deteriorate therewith.Traditional speaker mounting means, makes the speaker positioned at bottom of door form 30 ° ~ 80 ° angles with head part,
Human ear cannot listen to speaker direct sound wave the most flat.Internal loudspeaker mostly is paralleloscope shadow and is symmetrical arranged, sound wave during work
The mutual impulsive disturbance of meeting, although high pitch position is improved by some vehicles, angle of radiation also changes therewith it is difficult to obtain flat equal
The frequency response of weighing apparatus.When in-car all speakers work simultaneously, the position far and near distance due to reaching listener is different, radiation
Direction is different, and the radiation path of every speaker is different, through continuous reflection, the refraction of in-car many geometric surfaces, defines mistake
Comprehensive complicated chaotic sound field, in the process, a part of medium-high frequency can be absorbed by in-car bottom soft seat, and the strong low frequency of energy with
Standing wave sound then can more highlight, thus leading to former music high pitch dry and astringent, not penetrating；Middle pitch is thin, lacks unity and coherence；Bass is muddy,
The amount of having no matter.In addition, working as automobile in the process of moving, the grating from tire and road surface reaches human ear below car body, with
The lifting of speed, noise also can increase therewith.After the musical sound of speaker is superimposed with road noise, will make to have been contaminated by sound
Music deteriorates further, allows driver and occupant to be all difficult to not hear music content.
Content of the invention
For solve above-mentioned technical problem, the present invention provide a kind of small volume, little, the lossless installation that takes up room, convenient disassembly,
Integrated digital car audio system simple to operate, that application is flexible, tonequality reaches high-fidelity level.
For realizing above-mentioned technical purpose, be employed technical scheme comprise that：A kind of integrated digital car audio system, vehicle-mounted
