濟南汽車音響改裝http://www.szanyuda.com/低音炮的時候都習慣性的要求在低音炮里面裝上海綿，其實吸音棉用來吸收音箱內部的聲波，但是加海綿的話最好加玻璃棉，能夠消除部分的駐波。

濟南汽車音響改裝談到在開孔箱中，振動膜的反向運動將聲波從小孔推出，增強了整個聲級。低音反射音響的主要優勢在于效率高。移動驅動器的功率發出的聲波不是一種，而是兩種。其劣勢在于，沒有氣壓差將驅動器復原，因此，其發聲不是很精確。低音反射式揚聲器移動驅動器，可以產生兩種聲波。 當驅動器向前壓縮空氣，同時向后變薄，反之亦然。 箱體內壁鋪薄薄一層就夠了，不宜太多，只是起一個減少箱壁諧振和減少箱內反射聲波的作用，因為還要利用喇叭后面的空氣流跟前面的聲波融合。
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.
　　
濟南汽車音響改裝建議密閉箱填滿寬松為主，這些音箱完全密封，因此，沒有空氣泄漏。這意味著前向波能進出室外，而返波只能停留在音箱里。當然，因為無空氣泄漏，箱內氣壓不斷地發生變化，驅動器往里收縮，壓力增大;擴音器往外擴張，壓力降低。兩種運動都會在箱內和箱外之間產生壓力差。由于空氣始終起著平衡壓力差的作用，因此，驅動器總是不斷地接近“靜止”狀態，在此狀態，箱內外氣壓平衡。
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.
　　
濟南汽車音響改裝http://www.szanyuda.com/介紹在密封式揚聲器裝置中，驅動器隔膜往里收縮時，壓縮箱內空氣；驅動器隔膜往外擴張時，釋放空氣。 如果是密閉箱，那最好填滿，但不能壓緊，一定要寬松，吸音棉起增大箱體容積的作用。如果吸音棉太少，喇叭控制不住，會出現低頻模糊的現象，但太多了，低頻的下潛又不夠，而且聲音又干又死，必須一邊聽一邊調的。
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.
