Sound professional advice on the installation environment modification enthusias
Now many car owners are not satisfied with original sound effects and do modified car stereo, car sound effects actually sound itself is not bad, nor is it to install technology, but to install the environment!
Firstly, the installation of audio speaker stand, floor (door) is rigid enough, when the car's speakers sound, because sound speakers will not only forward transmission, but also backward transmission, when transmission of the sound waves back when the impact of bottom floor with the speaker will resonate or shake heavily, leading speaker sound pressure loss, caused by the speaker of the harmonic distortion, leading to quality deterioration; followed by installation of sound because the speaker stand, floor (door) of the seal is not enough, the bass speaker to before and backward sound waves in both directions of 180 degree phase difference, due to a longer wavelength low-frequency sound waves, diffraction are strong, the direction it is very poor, door speaker install the floor (the door) above is full of holes, backwards The acoustic radiation will be around to front and front acoustic offset, so that transmission of acoustic radiation energy forward greatly reduced (the sound short circuit), resulting in low frequency, less than! So do car stereo modification must be done to achieve the increased vehicle noise sound effect!
Car noise damping material is rubber material and an outer layer composed of two layers of metal sheet, when the body structure, vibration, rubber vibration damping material also will, but will be bound by the outer sheet metal, the attenuation of vibration transmission along the body structure energy, body vibration suppression, reduced production floor with the speaker resonance and shake heavily, so that speakers emit pure natural music; while noise material can penetrate into the body of detailed gap in the metal plate to the hole to seal his death, which the body into a solid seal the whole, and thus effectively improve the quality of car audio!
Select audio conversion! Select car noise! Enhance the sound quality! Reproduce music Original!
