Whether you are an audiophile or an ordinary music lover, there are at least one or two speakers in your home. You use them every day, but not everyone knows their treasures. This article for you to do a simple science, the raw materials of the box on the market, they each have what kind of characteristics.

Portable Bluetooth speaker, wooden raw materials we are the most common and the most popular is the wooden speaker, but it is worth noting that the wooden box is not equal to pure log. Wood board according to the classification of raw materials can be divided into solid wood, wood-based board two categories.

The first kind of natural solid wood, its cost is relatively high, in quality is also much heavier than the same volume of sound box, usually used in high-grade sound box. Solid wood speakers usually choose mahogany, rosewood, peach, sandalwood and other rare hardwood, it is best to have no seam of the whole board, the top material for the sound box production. But such materials are hard to find, expensive and difficult to process. Followed by flower willow, jujube wood, catalpa wood, etc., to be more serious, wood uniformity is better. The new material is wet and easy to deform, and can be applied after drying treatment. Therefore, sometimes in high-end goods, different wood will be regarded as a mark of commodity grade.

But for the vast majority of household users, the most common wood raw material is still wood-based panels. The density board, also known as fiberboard, is made of wood, tree technology and other objects soaked in water after hot grinding, paving and hot pressing. It is an artificial board made of wood fiber or other plant fiber as raw material and applied with urea-formaldehyde resin or other applicable adhesives. According to different densities, density boards can be divided into high-density boards (density ≥880 kg/cubic meter), medium density boards (density 550 kg-880 kg/cubic meter), and low density boards (density less than 550 kg/cubic meter). Because of its soft impact resistance, high strength, pressed good density uniform, but also easy to reprocess, but the disadvantage is poor water resistance. Therefore, to be used to do sound box box, the common practice is to stick skin.

Particle board, also known as particle board, bagasse board, made of wood or other lignocellulosic materials made of fragments, the application of adhesive under the action of heat and pressure of the wood-based board, also known as the fragment board. Mainly used in furniture and construction industry and train, car carriage manufacturing. Product particle board does not need to be dried again, can be used directly, sound absorption and sound insulation performance is also good. But it also has its inherent shortcomings, because the margin is rough, easy to absorb moisture, so the furniture edge sealing process made with particleboard is particularly important. In addition, due to the larger volume of particleboard, furniture made with it is relatively heavy compared with other boards.

Plastic raw material:

Plastic raw materials they have light, appearance plasticity and other characteristics. The advantage of plastic is that it is easy to process, the appearance can be done more beautiful, and the cost can be very low in mass production. But it does not mean that plastic is synonymous with low-grade, like some well-known brands at home and abroad, in high-end goods also use plastic raw materials, also can produce a good sound. We can't simply think that the sound quality of plastic material speakers is not as good as that of wood speakers. The material requirement of the sound box is not easy to produce resonance, which affects the sound quality. As long as the plastic sound box after some special design or use of special plastic materials, and have good process guarantee, also can achieve better acoustic effect.
