濟南汽車音響改裝http://www.szanyuda.com/專家強調音箱是整個音響系統的終端，其作用是把音頻電能轉換成相應的聲能，并把它輻射到空間去。音箱的性能高低對一個音響系統的放音質量是起著關鍵作用。

音箱之所以存在箱體主要是為了防止揚聲器振膜正面和反面的聲波信號直接形成回路，造成僅有波長很小的高中頻聲音可以傳播出來，而其他的聲音信號被疊加抵消掉了。音箱的物理模型是在一塊無限大的剛性障板上開一個孔，安裝揚聲器，這樣就能保證揚聲器正面和反面的聲音信號不會形成回路，造成音波回路。但實際使用中，音箱是不可能做成無限大的，因此，人們在揚聲器后面用障板形成一個密閉的空間，保證音波的正面傳輸。
Mainly exists speaker diaphragm of the speaker cabinet in order to prevent the front and back loops are formed acoustic signal directly, resulting in only a very small wavelength of high-frequency sound can be spread out, while the other sound signal is superimposed on the offset. Physical model of a speaker is in an infinite rigid baffle open a hole, install the speakers, so you can ensure that the front and back speakers sound signal does not form a loop, causing sonic loop. However, the actual use, the speaker is not possible to make infinite, so people in the back of the speaker to form a closed space with a baffle to ensure the transmission of sound waves in the front.

After the speakers closed due to atmospheric problems, speaker box is bigger and more beneficial to low-frequency sound reduction, therefore, generally the speaker volume is calculated according to the size of a woofer speaker compromise data. Many environment may still not allowed to have much of a box, people in order to further reduce the volume, but also according to the characteristics of sound waves and enhance low-frequency sound reproduction requirements of the design of the tank baffle, inverting the tube, resonator, etc., mainly to certain wavelengths in the low frequency band of the sound signal be enhanced and the atmospheric pressure to further reduce the effects of sound reduction.
