Collision is hit, and it is also proposed higher requirement to the structural strength of shell itself, therefore the material of this shell becomes particularly important,
The casing of loudspeaker box occurred on existing market is generally made using metal or alloy material, also adopts injection mo(u)lding, these materials
Exist clearly disadvantageous：
By taking metal or alloy material as an example, its production processes to realize essentially by punching press, die casting or CNC, and early stage is needed
Put into substantial amounts of die cost so that end product it is relatively costly, the market competitiveness is very low；And use metal or alloy material
Casing of loudspeaker box made by matter, the internal damping very little of material, itself can not absorb sound wave, cause audio distortions, and audio effect is poor；
In addition, this material technique in outward appearance application is complex, baking finish can only be typically adopted, it is difficult to reach anti-UV and anti-corruption
Erosion, and the temperature difference it is larger when lacquer painting easily burst, this coating process cost also than larger, finally, using works such as punching press, die casting
The outer casing thickness of skill processing procedure is universal less, after receiving and colliding with or clashes into, is very easy to depression, impact appearance.
By taking the casing of loudspeaker box of injection mo(u)lding as an example, equally substantial amounts of die cost, the market competition will be put in early stage first
Power is equally less；Secondly limited by Shooting Technique, its thickness is equally relatively thin, and relatively thin injection molding product structure intensity is poor,
During actually used, easily affected to produce resonance by sound wave, audio effect is equally poor；In addition, its surface is impacted

Extruding force, carry right bad between glass mesh sheet and shell, easily produce bubble or hollow gap, affect the structure of shell strong
Degree, or even in actual use, shell easily produces pit or breakage near hollow gap after impact is received, non-
Outward appearance is affected often；
Again, using spraying or the mode fitted, the Wall thickness uniformity of whole shell is very rambunctious, causes shell
Wall unevenness, causes internal damping power inequality everywhere, and the penetration level of sound is more chaotic, audio effect when causing actually used
It is not good；
Finally, due to only have layer of glass fiber mesh sheet in this material set, application thin film as structural strength is increased
It is very limited with effect of the anti-UV layers in raising structural strength, therefore whole shell still has to be strengthened in structural strength.
