Portable Loudspeaker Cabinet With Aluminium Speaker Cabinet and Full-Face Perforated Metal Grille

Consumer electronics portable speakers, home audio systems, and automotive dashboard speaker assemblies use an aluminium speaker cabinet where grille hole pitch uniformity and cabinet face squareness together determine acoustic transparency and driver mounting planarity; grille pitch variation above ±0.5 mm creates non-uniform open area distribution that shifts the free-air resonance frequency and reduces high-frequency transmission above 4 kHz, while cabinet face squareness above 0.5 mm per 100 mm prevents the driver flange from seating flush and introduces air leak paths around the gasket.
