The Importance of Sound Absorbent Cotton:
A ring of sound absorbent cotton is added to the rear of the horn,mainly for absorbing excess signals at a specific frequency band.In fact,the speaker is forward,backward will vibrate air transmission sound energy, in the speaker,the sound energy propagated backward will be a large proportion of the lock in the box, easy to cause standing wave and other bad sound image,resulting in hearing turbidity,so the absorbent cotton absorption of some frequency signals, and it can effectively reduce these problems.
