How to Ensure Sound Effect with High Power Professional Speaker
The difference between the professional speaker and the civilian speaker is in the bass. The sound emitted is very different. The bass of the civilian box is heard, and the bass of the professional box is felt. What is feeling, he is by the vibration of the air, convey to us, we feel the air waves, this feeling is very special. It's like being underwater, and we hear a lot of sounds, but it's also feeling. To feel this bass, the requirements for the box body are particularly high.
In high power, to achieve the perfect sound effect, we must focus on solving:
The first is box vibration. Because the vibration of the box body will offset the sound pressure of a specific frequency, causing distortion; The other box is structurally unstable. It can make a specific geometric noise. This noise is like the sound of two wooden boards hitting each other. Of course, this noise is caused by the wood and production processes. For example, the wood is easily deformed / the production process is backward / the wood is not straight when it is sawn into small pieces, and it is jagged, so that it can not be completely uniform during the bonding process., And there was later noise.
The second is horn unit resonance. Why use an aluminum basin frame because of the different unit structure? There is nothing special in low power. In high power, due to the effect of sound waves, the surface of the speaker will vibrate somewhat,(of course, the ideal speaker design, No vibration should be felt at any part of the speaker under high power.) This vibration is transmitted back to the unit fixed on top. If the unit speaker's frame is not strong enough, the bass basin will vibrate with the panel. At this time, the center position of the sound circle in the magnetic fluid will be damaged, causing serious distortion, and even causing rubbing, and finally the sound circle will burn.
Take C-MARK's FT04 professional full-frequency speakers. The bassoon of its bass unit is made of aluminum and is installed on the box body very firmly, with a thickness of more than 2.0 mm. The geometric deformation of the aluminum basin is much smaller than that of the stamping iron basin. Therefore, the professional speaker can not reduce the cost. The real material must be on the box and the horn unit. The quality of the speaker is good.
