Why is metal mesh better for sound cover?—Anping Dongjie Wire Mesh

With the improvement of everyone's quality of life, audio appears more and more frequently in the home. I wonder if you find that most audio covers are made of metal? So why is this? Today we will answer this question for you.

1. Better sound quality: The higher the material density of the sound cover, the smaller the vibration generated by the box when the sound is emitted, and the sound can be restored more realistically. Taking 304 stainless steel as an example, the density is 7.93 g/cm³; Moreover, the metal cavity has better sealing performance than other materials, the surround sound of the sound is stronger, and the output sound quality is also better. Too light speakers are easy to vibrate and make noise when playing songs, and the metal speaker shell can add weight to the fuselage to avoid noise.

2. High-end appearance: people are visual animals, and the pursuit of beauty is inevitable; 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 ambient temperature. If it is prone to thermal expansion and cold contraction, the airtightness of the sound will be reduced, the casing will loosen, parts will fall off, and the sound quality will also be affected by the sound; Take 304 stainless steel audio shell as an example, its high-temperature resistance reaches 800 ℃, which is much higher than the heat dissipation temperature of general electronic appliances. In addition, the metal material is more resistant to the impact of external forces, and is stronger and less prone to breakage.

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