With the popularity of audio, more and more families will also install audio, may many people will question, why metal material audio net cover will be more popular?

1. Better sound quality: The higher the density of the material of the audio casing, the smaller the vibration generated by the box when the sound is emitted, and the sound can be reproduced more realistically. Taking 304 stainless steel as an example, the density is 7.93 g/cm³ ; Moreover, the metal cavity is better sealed than other materials, the surround sound of the speaker is stronger, and the output sound quality is also better. An over-light speaker is easy to vibrate and make noise when playing songs, and the metal speaker shell can increase the weight of the body to avoid noise.

 
2. High-end appearance: People nowadays are more pursuing beauty in products; the texture of the metal shell is stronger, and the appearance is more high-end and fashionable; moreover, the metal surface is more resistant to dirt and easier to clean and maintain.

 
3. Temperature resistance and sturdiness: Metal is not easily affected by the ambient temperature. If it is prone to thermal expansion and contraction, the airtightness of the audio will be reduced, the shell will become loose, parts will fall off, etc., and the sound quality will also be affected by the audio; Taking the 304 stainless steel audio case as an example, its high temperature resistance can reach 800°C, which is much higher than the heat dissipation temperature of general electronic appliances. In addition, the metal material is more resistant to external impact, stronger and less prone to breakage.

 
4. Thermal conductivity: Every electrical appliance needs to dissipate heat, and smart audio is no exception; the thermal conductivity of metal will be better, and the thermal conductivity of 304 stainless steel is (100°C) 16.3W·m-1·K- 1. It can ensure that the sound quality of the speaker is not affected by heat; it can also prevent the parts inside from being worn out due to long-term high temperature, and prolong the service life of the product.
