Title (EN) ELECTRO-ACOUSTIC TRANSDUCER
(FR) TRANSDUCTEUR ELECTRO-ACOUSTIQUE
Abstract: front page image
(EN)The present invention refers to an electro-acoustic transducer (10) that includes an arrangement of at least two small thickness, low power and high impedance sound sources (20 - 29), available in a panel (30), where such arrangement must correspond to the relation Pt = ΣPi and lt = li/ΣN, where Pt is the total power of the electro-acoustic transducer in accordance with the present invention, and ΣPi is the sum of the individual power of each sound source (20 - 29) applied in the arrangement; and It is the total impedance of the electro-acoustic transducer in accordance with the present invention, li is the individual impedance of every sound source (20 - 29), and ΣN is the sum of the number of sound sources applied in the arrangement.
(FR)La présente invention concerne un transducteur électro-acoustique (10) comportant un montage constitué d’au moins deux sources sonores de faible épaisseur, de faible puissance et à haute impédance (20 - 29), disponibles dans un panneau (30), ledit montage devant obéir à la relation Pt = ΣPi et lt = li/ΣN, où Pt est la puissance totale du transducteur électro-acoustique selon la présente invention et ΣPi est la somme de la puissance individuelle de chaque source sonore (20 - 29) appliquée au montage ; et It est l’impédance totale du transducteur électro-acoustique selon la présente invention, li est l’impédance individuelle de chaque source sonore (20 - 29) et ΣN est la somme du nombre de sources sonores appliquées dans le montage.
