Speaking of Bluetooth speakers, many people think of its portable and convenient features. With the continuous development of Bluetooth technology, Bluetooth speakers also have the ability to low power consumption and long-distance transmission, which is also more and more popular with Bluetooth speakers. reason. The sound quality experience is a very important decision factor for users to purchase Bluetooth 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 material of the Bluetooth speaker shell. So, what are the materials for the CNC machining of the Bluetooth speaker shell? The following CNCMF CNC machining parts manufacturer will take you to find out.
1. Stainless steel
The stainless steel CNC machined bluetooth speaker shell is not only durable, but also has a metallic texture, is dirt-resistant, and has good sealing performance. Because of its good sealing, the sound quality of Bluetooth speakers will be better. at the same time. The stainless steel shell has a variety of surface processes, and hundreds of colors can be made. The surface paint process is the most widely used. The process makes the bluetooth speaker shell of CNC machining have good color rendering, bright color, good finish, and strong visual impact!
At the same time, the repairability is strong. If the traditional lacquer is damaged, the surrounding lacquer will fall off. There must be traces of spots when the paint is touched up. The baking paint is not easy to fall off and can be repaired without traces. Secondly, the stainless steel CNC machining of the Bluetooth speaker shell has a short construction period, and it does not require a lot of time and money to open the mold like the aluminum alloy CNC machining of the Bluetooth speaker shell.
2. Plastic
In fact, the plastic CNC machining of Bluetooth speakers is not as bad as you think, and it is not useless. The advantages of plastic CNC machining of bluetooth speaker shells are low price, diverse colors, and arbitrarily shaped shapes. At the same time, they are light weight and strong in plasticity, making them fashionable endorsements. In addition, plastic speakers seem to be very popular with young people, because plastic can make the shape of the speakers freely, and the color change satisfies the mentality of most young people in pursuit of uniqueness and individuality.
And the “enthusiasts” who usually play music for many years are “not cold at all” for the plastic CNC-machined bluetooth speakers. The reason is that plastic Bluetooth speakers generally do not achieve the sound quality they want. The bass effect is weak, the sound quality is thin and the roundness is very poor, and the plastic CNC processed Bluetooth speakers have poor texture and are not resistant to dirt. The box is thin and cannot overcome resonance.
3. Aluminum alloy
The aluminum alloy CNC machining bluetooth speaker shell is higher-end and elegant than the plastic shell, with a metallic texture, light weight and strong plasticity. Another powerful advantage is that it is easy to dissipate heat. However, the production of aluminum alloy CNC machining Bluetooth speaker shells requires a higher level of production technology.
Compared with the mold castings that have been developed for decades with mature and stable technology, the quality and output stability of the aluminum alloy CNC machining of Bluetooth speaker shells is poor, and the rejection rate is higher, resulting in higher prices for aluminum alloy CNC machining parts. There are many processes for the surface treatment of aluminum CNC machining Bluetooth speaker shells, and the cost of each process is different. The advantage of surface spraying is that there are many colors (commonly known as color aluminum), simple production and low price, but the disadvantage is color. The adhesion is not strong, it is easy to fall off, and it is easy to change color after a long time.
The above are the commonly used materials for CNC machining of bluetooth speaker shells. So, which material is suitable for Bluetooth speakers? There is no answer in the world. It can only be said that shells of different materials bear different missions, and there is no absolute difference between good and bad. I believe everyone knows what materials are used for CNC machining of bluetooth speaker shells?
