1, metal Bluetooth speaker shell: the metal shell has stronger texture and more upscale and fashionable appearance; Moreover, the metal surface is more resistant to dirt and easier to clean and maintain. Not easily affected by ambient temperature. If it is easy to expand with heat and contract with cold, the sealing performance of the sound will be reduced, the shell will be loose, the parts will fall off, and the sound quality will be affected by the sound. Take Foshan Zheng Gang 304 stainless steel Bluetooth speaker case as an example, its high temperature resistance reaches 800℃, which is much higher than the heat dissipation temperature of general electronic appliances. In addition, metal materials are more resistant to the impact of external forces, stronger and less prone to fracture.
2.abs:abs material is environmentally friendly. Because it uses environmentally friendly chemicals, it is non-toxic and tasteless, and can be electrically insulated from it. This is a safe material. Abs material is easy to deform in high temperature environment, the deformation temperature is 93- 1 18℃, but it has good performance in low temperature environment of -40℃, so it is also a material afraid of high temperature, with low dielectric strength and poor dissolution resistance.
Comparatively speaking, the metal Bluetooth speaker shell is better than abs; Foshan Zheng Gang Stainless Steel will answer your questions and hope to pass them.
