Description
Technical field
The present invention relates to a kind of sound equipment, specifically a kind of integrated digital car audio system.
Background technology
Being a special sound field environment inside car, not only interior spatial volume finite sum audition area is relatively
Little, and in the same space, there are two kinds of different acoustic characteristics: top, compartment is by roof, front-and-back stop glass and both sides car door
Glass constitutes a strong reflection sound field space, and the flexible materials such as the seat of bottom, compartment, carpet, patch make a large amount of sound wave quilt
Absorb, not only can stop the propagation of sound wave due to seat, and its irregular geometric jacquard patterning unit surface also can change the direction shape of sound wave
Become diffusion, thus constitute a complex sound field space not only having absorbed but also having reflected diffusion.
At present, the speaker of most of vehicle audios surveys bottom in being arranged on car door, is limited with cost by body construction, many
Loudspeaker are simply arranged on car door or body inner side, utilize it to press from both sides by the independent case body not matched inside number auto loud hailer
Layer cavity is as casing.Owing to car door material is plastics and iron sheet, its rigidity is low, damping error, internal volume are either large or small, geometric form
The factors such as shape does not mates, sound-absorption coefficient is inadequate, directly affects the normal performance of speaker electroacoustic performance.
Traditional speaker Installation Modes, can replay to music in car and listen to effect 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 characteristic, the most also can
Cause and the resonance of panel is installed and produces noise, so that original music tonequality is contaminated by sound, cause the distortion factor to strengthen.
The radiation characteristic of speaker is: frequency response the most smooth equilibrium when axial 0 °, and along with listening to the increasing of angle, frequency response is also
Deteriorate therewith.Traditional speaker mounting means, makes the speaker being positioned at bottom of door form 30 ° ~ 80 ° angles with head part,
Human ear cannot listen to the direct sound wave that speaker is the most smooth.Internal loudspeaker mostly is paralleloscope shadow and is symmetrical arranged, sound wave during work
Can mutual impulsive disturbance, although high pitch position is improved by some vehicle, but angle of radiation changes the most therewith, it is difficult to obtain smooth all
The frequency response of weighing apparatus.When speakers all in car work simultaneously, different owing to arriving the position far and near distance of listener, radiation
Direction is different, and the radiation path of every speaker is different, and in car, the constantly reflection of many geometric surfaces, refraction, define mistake
Combining complicated chaotic sound field, in the process, a part of medium-high frequency can be absorbed by bottom soft seat in car, and the strong low frequency of energy and
Standing wave sound then can more highlight, thus causes former music high pitch dry and astringent, the most penetrating；Middle pitch is thin, lacks unity and coherence；Bass is muddy,
The amount of having is without matter.It addition, work as automobile in the process of moving, the grating from tire Yu road surface reaches human ear below car body, with
The lifting of speed, noise also can strengthen therewith.After the musical sound of speaker superposes with road noise, will make to have been contaminated by sound
Music deteriorates further, allows driver and occupant all be difficult to not hear music content.
Summary of the invention
