Q: Which design changes to a trolley speaker can potentially affect mass production?

A: Design changes impacting trolley speaker mass production mainly cover cabinet housing structure, internal component layout, battery/power system, acoustic structure, panel cutout & button layout, material/surface finish and matching accessories. These may trigger mold rework, new jigs, re‑testing, extra cost and extended lead‑time. Simple color or print adjustments normally do not disrupt mass‑production. All structural design revisions need pre‑engineering evaluation for RFQ & order confirmation.
