Abstract
(EN)
The present invention relates to an electronic device, comprising: a speaker including a transducer provided in an enclosure of a housing and outputting sound on the basis of a sound signal and capable of amplitude movement on the basis of a first drive signal, and an active radiator capable of amplitude motion on the basis of a rear wave by the amplitude movement of the transducer and a second drive signal; and an amplifier for outputting the first drive signal corresponding to the sound signal and the second drive signal which assists the amplitude movement of the active radiator by the rear wave of the transducer so as to cause an output sound pressure of the active radiator to reach a target value.

La présente invention concerne un dispositif électronique, comprenant : un haut-parleur comprenant un transducteur disposé dans une enceinte d'un boîtier et délivrant un son sur la base d'un signal sonore et capable d'un mouvement d'amplitude sur la base d'un premier signal d'entraînement, et un radiateur actif capable d'un mouvement d'amplitude sur la base d'une onde arrière par le mouvement d'amplitude du transducteur et d'un second signal d'entraînement; et un amplificateur pour délivrer en sortie le premier signal de commande correspondant au signal sonore et le second signal d'entraînement qui assiste le mouvement d'amplitude du radiateur actif par l'onde arrière du transducteur de façon à amener une pression sonore de sortie du radiateur actif à atteindre une valeur cible.
