摘要

Loudspeaker chassis diaphragm (2) has through holes (1), which are formed oblong, oval or hole-type. The diameters and quantity of the through holes do not impair the rigid structure of the diaphragm. At least three through holes are evenly distributed over the diaphragm surface and have a diameter of 1 mm with smaller chassis under 10 cm diameter and with bass chassis accounting to a diameter under 1 mm.
