济南汽车音响改装谈到在开孔箱中，振动膜的反向运动将声波从小孔推出，增强了整个声级。低音反射音响的主要优势在于效率高。移动驱动器的功率发出的声波不是一种，而是两种。其劣势在于，没有气压差将驱动器复原，因此，其发声不是很精确。低音反射式扬声器移动驱动器，可以产生两种声波。 当驱动器向前压缩空气，同时向后变薄，反之亦然。 箱体内壁铺薄薄一层就够了，不宜太多，只是起一个减少箱壁谐振和减少箱内反射声波的作用，因为还要利用喇叭后面的空气流跟前面的声波融合。
Jinan car audio conversion box it comes in a hole, the reverse movement of the diaphragm sound waves launched from the hole, and enhance the overall sound level. The main advantage is that the bass reflex sound and high efficiency.

Acoustic power emitted by mobile drive is not one, but two. Its disadvantage is that there is no pressure difference will drive recovery, therefore, its sound is not very accurate. Bass reflex speaker removable drive, you can produce two kinds of sound waves. When the compressed air drive forward, rearward while thinning, and vice versa. Spread a thin layer of the inner wall of the box is enough, not too much, just from a reduction in the resonant tank wall and reduce the role of the reflection of sound waves inside, because even the use of air flow behind the speaker with the front of the acoustic fusion.
　　
济南汽车音响改装建议密闭箱填满宽松为主，这些音箱完全密封，因此，没有空气泄漏。这意味着前向波能进出室外，而返波只能停留在音箱里。当然，因为无空气泄漏，箱内气压不断地发生变化，驱动器往里收缩，压力增大;扩音器往外扩张，压力降低。两种运动都会在箱内和箱外之间产生压力差。由于空气始终起着平衡压力差的作用，因此，驱动器总是不断地接近“静止”状态，在此状态，箱内外气压平衡。
Jinan car audio conversion proposal airtight box filled with loose-based, these speakers is completely sealed, so that no air leaks. This means that out of the forward wave energy outdoors, and backward wave can only stay in the speakers. Of course, because there is no air leakage, the inside air pressure is constantly changing, the drive inside the contraction, the pressure increases; outward expansion microphones, pressure is reduced. Two movements are in the box and outside the box to generate a pressure difference between. Because the air plays an equilibrium pressure difference, therefore, always try to drive close to the "stationary" state, in this state, pressure balance inside and outside the box.
　　
济南汽车音响改装http://www.sdcarmusic.com/介绍在密封式扬声器装置中，驱动器隔膜往里收缩时，压缩箱内空气；驱动器隔膜往外扩张时，释放空气。 如果是密闭箱，那最好填满，但不能压紧，一定要宽松，吸音棉起增大箱体容积的作用。如果吸音棉太少，喇叭控制不住，会出现低频模糊的现象，但太多了，低频的下潜又不够，而且声音又干又死，必须一边听一边调的。
Jinan introduce modified car stereo speakers in a sealed device, the drive inside the diaphragm contraction, compressed air inside; when you drive out of the expansion of the diaphragm, the release of air. If it is a closed box, it is best to fill, but not pressing, we must loose, absorbent cotton from the cabinet volume increased role. If too few sound-absorbing cotton, speakers uncontrollably, there will be low-blurred, but too much and not enough bass dive, and the sound is dry and dead, we must listen and tune.
