The size of the bass speaker is a little larger and full of weight in the speaker family. Let you know at a glance that this is a heavyweight player. The position of bass in music is the same. When a piece of music has a strong low voice, you can feel the momentum is very grand and full of energy, with a strong sense of shock. The "appetite" of the bass speaker is amazing, and the energy consumed by the bass speaker is even several times more than that of the tweeter plus the bass speaker.
The role of the woofer in the car audio is to make the music more passionate and shocking, to truly create an infectious music atmosphere, and to "mask" various low-frequency noises during the car standby. The bass speaker has many advantages and is indispensable, but it also has a very "tough" personality. The power amplifier with mismatched temperament sounds bad. The unreasonable geometric shape and volume design of the box can not make it exert its full strength. The use of sound absorbing materials is also very knowledgeable. The main problem is that the sound pollution or noise caused by the resonance of the box and the resonance of the car body structure diagram is more difficult to avoid.
It is almost impossible to completely solve this problem, but we still have to face the reality and solve this problem rationally. The solution is to reduce the parallel planes of the subwoofer as much as possible to make it difficult to form standing waves; Reinforcing rib shall be made in the box to reduce box vibration; The volume of the box and the size of the phase guide pipe shall be made in strict accordance with the parameters given by the manufacturer. The sound absorption damping in the box cannot be omitted. The interior trim panel and the parts that are easy to cause vibration shall be damped and sound absorption treated as far as possible. All other parts in the car that can cause resonance should also be dealt with accordingly. If the above measures can be taken, the bass of your car's audio system must be improved in quality, so that the level of the whole car's audio system can be greatly improved, or even refreshed. It sounds like a "cool" feeling that has never been seen before.
The woofer is the woofer unit in the car speakers, which is used to replay the low-frequency signal (generally in the frequency range of 20Hz-150Hz) output from the frequency divider. Generally speaking, the larger the diameter of the woofer, magnet and voice coil, the better the low frequency playback performance and transient characteristics, and the higher the sensitivity.
The structure of bass speakers is mostly cone basin type, and a few are flat plate type. There are many kinds of diaphragm for bass speakers, including aluminum alloy diaphragm, aluminum magnesium alloy diaphragm, ceramic diaphragm, carbon fiber diaphragm, bulletproof cloth diaphragm, glass fiber diaphragm, acrylic diaphragm, paper diaphragm, etc. The bass unit with aluminum alloy diaphragm and glass fiber diaphragm is generally small in diameter and has a large bearing power, while the bass unit with reinforced paper basin and glass fiber diaphragm has an accurate timbre and good overall balance when replaying music.
The influence of the sense of space (AMB) on the replay effect depends largely on the performance of the subwoofer. The enemies of car audio are engine sound, driving chatter and wind noise, which are mainly concentrated in the bass part. Overcoming these noises and the weakening of bass effect caused by the internal structural conditions of cars is the primary task of car bass speakers. In addition, it is the requirement of many car audio enthusiasts to show rich and deep sound effects.
