Smart speaker shell generally use stainless steel, aluminum alloy and plastic more. Stainless steel shell has the advantages of stainless steel, metal texture, good sealing, better sound quality, plasticity, antioxidant, low processing difficulty, short construction period, cost savings; while the aluminum alloy mold opening time is long, slow processing speed leads to increased production costs; plastic is not stain-resistant, low texture, low strength, by the influence of temperature leads to thermal expansion and contraction, sealing is poor. Therefore, the comparison is still stainless steel smart speaker shell will be better.
