Abstract:
A bass reflex port including: a tubular body portion; and a surface forming portion which is board-like, and continuous to an inner wall of the tubular body portion and which has a surface extending radially outwardly from an opening end of the tubular body portion disposed in a housing of a speaker, wherein the surface forming portion extends linearly in a direction away from a tube axis of the tubular body portion in a cross section parallel to the tube axis.

Claim (Index 9):
The bass reflex type speaker according to  claim 6 ,\n wherein the tubular body portion has a straight portion whose perpendicular cross-sectional area is constant in a direction of the tube axis and a flare portion whose perpendicular cross-sectional area increases from a boundary at the straight portion toward the opening end, the perpendicular cross-sectional area being an area of a cross section of an air-flow passage in a direction perpendicular to the tube axis, and wherein a cross-sectional area of the air-flow passage between the inside housing first surface and the inside housing second surface at the opening end of the flare portion is greater than or equal to about one time the perpendicular cross-sectional area of the straight portion and smaller than or equal to about 2.5 times the perpendicular cross-sectional area of the opening end of the flare portion.
