(FR) APPAREIL DE PROTECTION DE HAUT-PARLEUR ET PROCÉDÉ ASSOCIÉ
Abstract
(EN)
An apparatus comprises at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: determine at least one parameter of a transducer on the basis of received information; and modify a received signal for actuating the transducer on the basis of the determined parameters of the transducer and a frequency spectrum of the received signal. The apparatus protects the transducer from damage due to excessive displacement caused by the received signal
(FR)
La présente invention se rapporte à un appareil comprenant au moins un processeur ; et au moins une mémoire comprenant un code de programme d'ordinateur, la ou les mémoires et le code de programme d'ordinateur étant configurés pour amener, à l'aide du ou des processeurs, l'appareil au moins à : déterminer au moins un paramètre d'un transducteur sur la base des informations reçues ; et modifier un signal reçu pour actionner le transducteur sur la base des paramètres déterminés du transducteur et d'un spectre de fréquences du signal reçu. L'appareil protège le transducteur contre des dégâts dus à un déplacement excessif provoqué par le signal reçu.
