Vehicular speaker use

The speaker is more prominent in the car audio system. To let the car speakers show a good tone and positioning, compared with the home audio, technical requirements and difficulties are higher than many. In vehicle speaker unfavorable factors and different and complex, because in the vehicle interior space, some of the houses are not represented the unfavorable factors: narrow space, irregular objects, complex environment (noise, vibration, vehicle materials etc.) and speaker of the installation position from inside and outside of the car styling (limited); more important is to listen to poor location, left side, partial right, two parties; and as the speaker is not a positive mean symmetric point to, resulting in the complex frequency, phase difference and wave crest and trough, standing wave, reflection moveout and reverberation time is too long (resonance) and so on, is not conducive to hear. Nevertheless, we can still through the understanding of sound system equipment attribute, use, categories, compatible and speaker characteristics, and correct installation experience and skills, correctly handle the installation position of the different bandwidth speaker, keep the good directivity, technical adjustment of power amplifier and phase content, achieve good results.
