Abstract

L'invention a pour objet un transducteur électroacoustique à fréquence de résonance principale, comportant un corps de transducteur ayant une première et une seconde surface opposées, une première série de rainures taillées dans cette première surface et une seconde série de rainures taillées dans la seconde surface, les premières rainures étant disposées sous un certain angle par rapport aux secondes rainures. Dans ce transducteur, au moins quelques-uns des côtés des premières rainures forment contact avec les côtés des secondes rainures de telle sorte que les résonances autres que la première fréquence de résonance soient supprimées. Application à l'élimination des résonances de mode non souhaité.
