Abstract

La présente invention concerne un ensemble de transducteurs acoustiques. Cet ensemble comporte une couche de matériau support (2). Un circuit électrique (3) est intégré à ladite couche de matériau support. Une pluralité de transducteurs (4) est montée sur la couche de matériau support pour former au moins une partie d'un réseau de transducteurs. Un évidement ou une ouverture (12) sont pratiqués entre une paire de transducteurs (10, 11) du réseau de transducteurs. Cet évidement ou cette ouverture (12) peuvent représenter un évidement ou une ouverture (12) du matériau support (2) entre une paire de transducteurs (10, 11) de la pluralité de transducteurs montée sur la couche de matériau support. La couche de matériau support (2) peut être rigide ou souple. Un support rigide (501) peut servir à soutenir au moins un transducteur (502) de la pluralité de transducteurs.
