SPEAKER, commonly known as speaker, is an indispensable important equipment in a sound system. All music is sounded through speakers for people to listen and enjoy. As the only device that transforms electrical energy into "sound energy", the quality and characteristics of the speakers play a decisive role in the sound quality of the entire sound system. Due to the particularity of the car, it is not possible to install universal speakers like a home theater in the car, but to directly install each car speaker on the car, a high-end car can even install more than ten speakers. The speakers mainly include double cone, two-way, three-way, independent component type, subwoofer and so on. The independent component type includes an independent tweeter unit, an independent midrange unit and a crossover network, and is generally installed at the front door of the car. In general, the larger the caliber of the speaker, the better the low frequency, so if you like to listen to bass, it is best to match a larger caliber speaker. The importance of speakers in car audio systems is more prominent. To make car speakers show excellent sound and positioning, compared with home audio, the technical requirements and difficulties are much higher. The unfavorable factors of car speakers are numerous and complicated, because there are some unfavorable factors in the interior of the car that are not available in the house: narrow spaces, irregular objects, complex environments (noise, vibration, vehicle materials, etc.) and The installation position of the speaker (limited by the shape of the car's inside and outside); more importantly, the listening position is not good, left and right; and because the speaker's pointing is not positively symmetrical on the front, resulting in complex frequencies, phase differences and peak , Troughs, standing waves, reflective jet lag, reverberation time is too long (resonance), etc., is not conducive to listening problems. Nonetheless, we can correctly handle the installation position of speakers of different bandwidths and maintain their good orientation by understanding the properties, uses, categories, compatibility and speaker characteristics of sound system equipment, plus the correct installation experience and skills It is technically calibrated with compatible power amplifiers to achieve good results.
