Bluetooth speaker factory teaches you how to improve the sound effect in the car

Bluetooth speaker manufacturers often hear that many car owners say that the sound effect in the cab is not good. In fact, it is not difficult to improve the sound quality of their car. The editor of Fandou Technology will introduce you the following solutions:

First of all, we must start with the audio source. The tape drive has a narrow frequency response and high noise, so there is no need to consider its use. At present, CD players or MD players should be the objects of choice. CD should use a model without any modification to the signal, that is, the so-called "authentic", because the modified signal is not the original signal and has been distorted, so the signal played may not be ideal. It is best to choose a CD player with a high front output power level, generally 2V-4V, which can improve the signal-to-noise ratio. CD records should be used with genuine products with the words "DDD" printed on the surface. The sound quality of such records should be very good. When choosing a speaker, you should first consider what kind of system to use. If you choose a music quality system (playing classical music, symphony, light music, etc.), you should choose speakers with clear and soft sound quality. If you choose a volume-based system (playing disco, rock music, etc.), you should choose a speaker with a firmer and larger dynamic range. When choosing a power amplifier, the main consideration is the power, sensitivity and impedance matching of the power amplifier and the speaker. If you want to make the car audio reach the fever level, you can choose an electronic crossover. After the main equipment is selected, the power cord, fuse holder, signal line, speaker line, etc. used by the system must be selected. When installing, the speaker should be positioned reasonably, and all equipment should be installed firmly, not to produce noise, but also to prevent interference. The power line and signal line must be separated, and the ground line must be installed at the main grounding point. When debugging, the main sound field should be the driver and the front seat. The high, mid and mid bass are generally in the front, and the bass should be in the rear of the car. When adjusting the high, medium, and bass, which part should be tuned first or second can be determined according to everyone's habits. There is no fixed mode, but the music should be played perfectly in the end.
