The difference between normal loudspeaker and car's loudspeaker

Loudspeaker is very important in car sound system. To make the car speaker show excellent timbre and positioning sense, the technical requirements and difficulty are much higher than that of home audio. There are many and complex adverse factors for on-board speakers, because in the internal space of the car, there are some adverse factors that are not available in the house: narrow space, irregular objects, complex environment (noise, vibration, vehicle materials, etc.) and the installation position of speakers (limited by the internal and external shape of the car); More importantly, the listening position is poor, left and right; Moreover, because the direction of the speaker is not front average symmetry, it leads to complex frequency, phase difference and crest, trough, standing wave, reflection time difference, long reverberation time (resonance), etc., which is not conducive to listening. Nevertheless, we can get good results by understanding the properties, uses, categories, compatibility of sound system equipment and the characteristics of speakers, plus correct installation experience and skills, correctly handling the installation positions of speakers with different bandwidth, maintaining their good directivity, and making technical adjustment with compatible power amplifiers.
