济南汽车音响升级http://www.sdcarmusic.com/介绍低音扬声器就是车载扬声器中的低音喇叭单元，其作用是将从分频器输出的低频信号(频率范围一般在20Hz-150Hz)重放。一般来说，低音扬声器的口径、磁体和音圈直径越大，低频重放性能、瞬态特性就越好，灵敏度也就越高。
Jinan subwoofer car audio upgrade is introduced in Car Speakers Woofer, whose role is to low-frequency signal from the divider output (usually in the range of frequencies 20Hz-150Hz) replay. In general, the woofer diameter, the larger

the diameter of the magnet and voice coil, bass reproduction performance, transient behavior, the better, the higher the sensitivity.
      
济南汽车音响升级谈到低音扬声器的结构形式多为锥盆式，也有少量的为平板式。低音扬声器的振膜种类繁多，有铝合金振膜、铝镁合金振膜、陶瓷振膜、碳纤维振膜、防弹布振膜、玻璃纤维振膜、丙烯振膜、纸振膜等等。采用铝合金振膜、玻璃纤维振膜的低音单元一般口径比较小，承受功率比较大，而采用强化纸盆、玻璃纤维振膜的低音单元重播音乐时的音色较准确，整体平衡度不错。
Jinan structure subwoofer car audio upgrade talked mostly cone type, there are a small number of flatbed. Woofer diaphragm variety, aluminum diaphragm, diaphragm-magnesium alloy, ceramic diaphragm, diaphragm carbon fiber, Kevlar

diaphragm, glass fiber diaphragm, propylene diaphragm, diaphragm, and so on paper. Aluminum alloy diaphragm, general caliber glass fiber woofer cone is relatively small, relatively large power to bear, and the use of reinforced cone,sound reproduction music fiberglass cone woofer more accurately, the overall balance is good.
      
济南汽车音响升级http://www.sdcarmusic.com/讲述空间感(AMB)对于重播效果的好坏的影响，很大程度上取决于超低音的表现。汽车音响的大敌是发动机音、行驶振颤音与风声，这部分声音主要集中于低音部分，克服这些噪音以及汽车内部结构条件致使的低音效果削弱问题，是汽车低音扬声器的首要任务。
Jinan car audio upgrade about a sense of space (AMB) for the replay is good or bad influence depends largely on the performance of the subwoofer. The enemy is the engine of car audio sound, the sound vibrations travel with the wind,

this part focuses on the bass sound, the noise and the vehicle's interior to overcome these structural conditions causing weakening bass problem, is the primary task of the car subwoofer.
