Abstract

La présente invention concerne un embout buccal d'instrument ayant une paroi intérieure qui comprend une pluralité de modifications curvilignes qui perturbe l'écoulement d'air à travers l'embout buccal afin de produire un son agréable lorsqu'un joueur joue d'un instrument. Les modifications peuvent comprendre des crêtes curvilignes surélevées disposées sur le déflecteur ou des vallées curvilignes incurvées dans le déflecteur. De plus, les modifications peuvent comprendre des motifs spécifiques conçus pour déclencher des sons différents mais toujours agréables à partir de l'instrument. Ces motifs peuvent comprendre un premier motif ayant une première modification linéaire centrale encadrée par un ensemble de modifications ayant des modifications allongées paraboliques, chaque modification ayant un foyer parabolique de plus en plus éloigné de chaque modification respective dans une direction opposée à la modification centrale et également encadré par un ensemble de modifications ayant des modifications allongées paraboliques façonnées dans la direction opposée. Un autre motif peut comprendre des modifications qui sont linéaires mais espacées les unes des autres dans un motif de plus en plus éloigné.
