The car audio endless elm 327 reasons

Overall, some owners think the car audio  elm 327  performance difficult satisfactory, in addition to the defects of the product itself, may be three causes.Install speaker bracket resonance lead to the degradation of sound quality. The utterance of the speaker in the car, since the speaker installed floor is relatively fragile, the bottom plate with the speaker will produce resonance or dither, resulting in speaker sound pressure loss, and cause harmonic distortion of the speaker (s), resulting in degradation of sound quality.Second, the "sound short-circuit" the impact of low-frequency radiation. The woofer diaphragm in the front-to-rear movement, in addition to sound waves radiated forward, there are sound waves radiated rearward, a difference of 180 degrees in the two directions of the phase of the acoustic radiation. Due to the very long wavelength of the low-frequency acoustic waves, the diffraction capability is quite strong. Therefore, the directivity of the low frequency sound waves is weak, due to the door speaker mounting panel above full of holes, the backward radiation of the acoustic wave will wraps around the front and the front of the radiation isobutyl phase elimination forward on the overall acoustic radiation energy greatly weakened, and this phenomenon is called "sound shorted". Sound short "does not seek to eliminate low-frequency radiation will not be able to effectively., Speaker installation space  launch x431 gx3    is irregular, causing sonic deformation. The sound field Irregular various sound quality is the main reason for the decline: car audio speaker sound, the sound waves not only fed forward but also backward transmission, strong reflection and special reflective sound confusion the sound conduction effect is not clear.Car stereo easily distortedJBL car audio engineering Guo SIR from the home audio, car audio, car audio special working environment. Home audio are installed in a relatively stable, relatively quiet space, little influence by outside noise, car audio.First of all, it is installed in a very small and limited space inside, but also by a great influence on the noise of the external environment and the car itself. Caring people may find that, when it ran in the road listening to music, and then suddenly stopped the car, you will find the music will be loud many, this is because the noise generated by the car running when swallowed part of a musical sound.Furthermore, the owners need to look at the speaker's work environment, home stereo speakers are mounted above the heavy wooden box, basically horn resonance is reduced to zero, so the sound quality is very mellow out. Car audio due to the limitations of space and the structure of the car itself, can only be installed in the doors, the boot or back porch board, the backplane are very thin tin, will lead to the entire bottom plate tin vibration speaker sound out This caused the distortion of the opel tech2    speaker, the speaker of the front and back of the volume is the same, is facing the car, good cushioning around it on the line, front and back out of the sound in front iron, when the volume reaches a certain extent, the impact of the sound waves of the iron will cause the shock of the iron, this will produce a certain amount of noise, do damping soundproof iron part
