What material does the speaker shell have?

Speaking of speakers, many people think of its portable and convenient features. With the continuous development of technology, speakers also have the ability of low power consumption and long-distance transmission, which is why speakers are becoming more and more popular. The sound quality experience is a very important decision-making factor for users to buy speakers. The shape design, process fit and material selection of the sound cavity also play a great role in gaining audio radiation and reducing resonance and distortion. This is related to the problem of the speaker shell material. So, what is the material of the speaker shell? Below Gang is stainless steel with you to understand.

1. Stainless steel

Stainless steel speaker shell is not only strong and durable, but also very metal texture and dirt resistance, good sealing performance. Because of its good sealing, the sound quality of the speaker will be better. At the same time. Stainless steel shell has a variety of surface technology, color can do hundreds of kinds, the surface of the paint process is most widely used. The process makes the speaker shell color good, bright color, good finish, with a strong visual impact! At the same time, the repair is strong. If the traditional paint surface is damaged, the surrounding paint surface will fall off, and there must be spots when repairing the paint, while the baking paint is not easy to fall off, can be repaired without traces. Secondly, the production of stainless steel shell construction period is short, do not need to open the mold like aluminum alloy shell need to spend a lot of time and money.

2, plastic

In fact, plastic speakers are not as bad as you think, and they are not useless. The advantages of plastic shells are low price, diverse colors, can be arbitrarily formed, and at the same time, light weight, shape plasticity, making them a fashion endorsement. In addition, the plastic speaker seems to be very popular with young people, because plastic can make the shape of the speaker become arbitrary, and the color change satisfies most young people's pursuit of uniqueness and individuality. And usually play music for many years of "enthusiasts", for plastic speakers "no cold". The reason is that plastic sound boxes generally do not reach the sound quality they want, the bass effect is weak, the sound quality is thin and the roundness is very poor, and the plastic sound box shell has poor texture, dirt resistance, thin box body and cannot overcome resonance.

3. Aluminum alloy

Aluminum alloy speaker shell than plastic shell high-end atmosphere on the grade, a metal texture, and light weight, strong plasticity. There is also a powerful advantage, is easy to heat. However, the production of aluminum alloy shells requires a high level of production technology. Compared with the development of decades of mature and stable mold castings, the quality and output of aluminum alloy shell stability is poor, the scrap rate is higher, resulting in higher prices of aluminum alloy products. There are many kinds of surface treatment of aluminum shell process, the cost of each process is different, the advantages of surface spraying is the color (commonly known as color aluminum), simple production, cheap, the disadvantage is the color adhesion is not strong, easy to fall off, time is easy to change color.
