The relevant problems of the car loudspeaker

Car loudspeaker is very important in car sound system. In order to show excellent timbre and positioning, the number of  car speakers and their layout are very important conditions. Speaker and effect: in the field of car audio, people have been pursuing such an effect: sitting in the car is like sitting in front of the stage. All the sounds are made from the front windshield. Closing your eyes is like feeling at the concert scene. The sound of each instrument can achieve the best replay effect. This is what we usually call professional hi fi (high fidelity) effect. To achieve the ideal hi fi effect, the key is to achieve sound source synchronization and the same amplification ratio of signals in each frequency band. (Car loudspeaker)This is not difficult for home stereo. Because the high, medium and low frequency units of household audio are placed in the same fixed box, and all music signals are amplified by the same power amplifier, the same amplification ratio makes it easier to achieve a good timbre balance. However, the car audio is different. Due to the limitation of installation position, the subwoofer unit can only be installed in the rear luggage compartment, the bass unit can only be installed in the lower front of the door, and the tweeter unit is generally installed near the A-pillar. The effect of this is likely to only hear the high voice in front and the low voice from behind, while the middle voice is weak. In addition, due to the different amplification and power requirements of different units, car audio can only adopt the way of driving speakers with multiple power amplifiers (many low-frequency parts need to be amplified by multiple power amplifiers), so it is difficult to achieve an ideal level in terms of timbre balance.
