Common Manufacturing Problems in Voice Device Housings
Many voice interaction device projects encounter acoustic and production issues when moving from prototype validation to mass manufacturing.
- Inconsistent speaker grille openings
- Microphone holes blocked by flash or deformation
- Poor fit between acoustic chambers and electronic modules
- Warpage on curved or glossy cosmetic surfaces
- Sink marks around screw bosses and internal mounts
- Vibration noise caused by weak housing structures
- Heat buildup around AI processing modules
- Assembly interference between PCB, speaker, wiring, and plastic parts
DTG TECH helps customers identify and solve these issues through DFM analysis, moldflow simulation, acoustic structure review, and production-oriented enclosure optimization.
