This invention provides a speaker port with a flare (304) having an inner wall that minimizes or reduces boundary layer separation. Fluids, such as air and sound waves, flow through the port at a higher velocity when boundary layer separation is minimized or reduced. The inner wall of the port is contoured so that the pressure gradient or change in pressure along the longitudinal axis of the port from its inlet duct (312) to outlet duct (314) is substantially constant.

La présente invention concerne un évent de haut-parleur pourvu d'un rebords présentant une paroi interne conçue pour atténuer ou pour réduire le décollement de la couche limite. Des fluides, tels que l'air et des ondes acoustiques, s'écoulent à travers l'évent à une vitesse plus élevée lorsque le décollement de la couche limite est atténué ou réduit. La paroi interne de l'évent est profilée de telle sorte que le gradient de pression ou le changement de pression le long de l'axe longitudinal de l'évent depuis la manche d'entrée d'air vers la manche de sortie d'air soit sensiblement constant.
