What's using a box ??'s case
Once the loudspeaker revive the sound, its own cone pouch will vibrate before and after. In the event the cone compels against the air flow from the cone to the other hand, instead of radiating the sound wave this really is the acoustic circuit. The phenomenon of short circuit may cause loudspeaker's sound pressure frequency feature to deteriorate, resulting in frequency distortion. The scene of madness, the greater the pressure, the larger the distortion, alto source components in bass loudspeaker vibration slightly larger.

Four, extend the frequency of single speaker apparatus and decrease distortion. We request the loudspeaker to actually restore the first voice. The selection of the human ear is about 20-20KHZ, however, the frequency array of the general loudspeakers is restricted, and it is difficult to consider the frequency of low and high frequencies to reach such a frequency array. So we want at least two speakers units on the box, which are liable for every frequency group. However, the pitch monomer is set by some speakers and style it to a unit, that has broadened the frequency band. However, for the first two things, we still have to put it.

4 wavelength loading, labyrinth and so forth. The bass loudspeaker shut type, followed by inverted stage and is composed of general and double cavity double launching.
Eliminate short circuit.
The use of the sound box can't be said half a half, the easiest way, the exact same piece of audio, you utilize the sound box after listening, then the unit down, and listen again, the difference is like the difference between salt and sugar as big!
Today, most of them are inverted phase layout, followed by shut 1 and workers.
Three. The horn unit's resonance is curbed.
In order not just to simulate the infinite baffle, but also increase the practicality of the speaker and make it more beautiful, the outer aspect of the baffle is folded back and folded into a box. In general, the vast majority of wood stuff.
So as to solve the noise wave short circuit, then we must extend the transmission distance of the acoustic cone basin before and after. The best way is to set up the loudspeaker onto a wooden plank. This way is known as baffle speakers.
In the acoustic point of view, the box accounts for the design of a frequency group on the 1 hand and calms the Dot of a frequency band through the inclined plane. There's a function to raise the negative pressure on the rear of the horn unit to ensure it is not "reach the floor" (breaking sound) in the high power output, and increase the flow of the unit and higher power. It plays the most incisively after the energy amplifier is combined.
On the other hand, people are sensitive to the soprano, and also the bass are comparatively slow, therefore it is more necessary to use the resonance of this box to grasp the bass, so that it's elastic and not overly exaggerated.
The shell of the sound box occupies more than 50% of the value! The loudspeakers in the world, in front of the spectrum analyzer, the operation of each frequency band is different, it is impossible to have a direct line functionality. We will need to enhance and compensate for the shock and resonance elimination of this box.
2, so as to extend the transmission distance, the bigger the greater baffle requirements. This restricts the use of open baffle speakers.
Once the very low frequency loudspeaker is resonant, the amplitude of this cone is the biggest, so the stimulation of this loudspeaker increases clearly. A box's low frequency play limitation begins from the resonant frequency of the low frequency horn component. Therefore, in order to lower the distortion in the low frequency loudspeaker's frequency, the impedance peak of the horn component at the frequency should be suppressed along with the amplitude of this cone is reduced. The impedance of this box may suppress the summit of the frequency loudspeaker at the adrenal gland, so as to reduce the distortion.
Box type sound box includes: closed type, bass type (domestic used inverted stage kind), vacant paper bowl kind, belt overall kind, labyrinth type, horn kind, barbell kind, air flow kind, and so forth.
