Which kind of material is used to make sound box, in fact, this will have a great impact on the sound quality effect of computer audio 2.0 itself. Sound box is qualitative character, can divide commonly for plastic, glass, woodiness and metal 4 chunk. Plastic and wood are the mainstream speakers on the market. Glass and metal are rare materials. Generally speaking, plastic materials are mostly used in the low and middle end of the market, such as subwoofers and sound, while wood is mostly used in the high end of the market, such as bookshelves and floorboards.
Plastic Speakers 
The price of sound box that plastic material pledges pledges is relatively cheaper, the price is commonly 10 to 3 400 interval to differ; And most of the portable Bluetooth speakers also use plastic material manufacturing, because of its unique plasticity is very strong, plus rich color, compact and light, convenient to carry at any time and anywhere. But plastic is light and not as dense as MDF, which makes it easier to resonate and thus not as good as wood speakers in terms of sound quality.
Metal speaker
Usually we see this kind of sound box on market is rareer, have not known however the price of this kind of sound box already exceeded commonly get computer acoustics 2.0 get a price, the sound quality of its oneself wants to be better than common woodiness of course get sound quality much; As we all know, the iron density is much higher than MDF version, and the hardness is also strong, can to a large extent, the generation of less resonance, will be low, medium and high frequency more accurate reduction; And this series of speakers have a more complex internal circuit design, will eventually present a better sound.
Glass speakers
At present part big brand is abroad, seek the sound box with beautiful sex and artistic quality tall, and choose glass to do sound box case. But the focus of this material is that it's a stylish plexiglass, not a traditional silica glass. Different from the traditional definition of glass, it is not as easy to break as the ideal material, and has good chemical stability, transparency, weather resistance and mechanical properties.
Wooden Speakers 
To create wooden structure speakers, can effectively reduce echo, resonance, so that the sound quality is more full and more pure, wooden audio is widely used in bookshelves, floor and other high-end market, is also the majority of pink enthusiasts to enjoy the best music of the necessary goods. Its colors are mostly black, brown and deep red, extending a simple and calm, atmospheric temperament.
90% of the material used in wood audio is MDF MEDIUM density fiberboard, which is made of wood fiber or other plant fiber as his pure raw material through processing technology. (Such as broken, fiber separation, drying fully after adding adhesive, and then by hot pressing made into an artificial board.) Uniform density, smooth surface, thickness is 5-30mm. This kind of plate has excellent physical properties, easy processing, decoration, so it is widely used in the manufacture and production of sound.
