Title (EN) DISPLACEMENT LIMITER FOR LOUDSPEAKER MECHANICAL PROTECTION
(FR) LIMITEUR DE DÉPLACEMENT POUR PROTECTION MÉCANIQUE DE HAUT-PARLEUR
Abstract:
(EN) One embodiment provides a device comprising a speaker driver including a diaphragm. The device further comprises a controller configured to receive a source signal for reproduction via the speaker driver, determine an estimated displacement of the diaphragm resulting from the reproduction of the source signal, and generate a control voltage based on the estimated displacement and threshold information relating to safe displacement of the diaphragm. An actual displacement of the diaphragm during the reproduction of the source signal is controlled based on the control voltage.
(FR) Un mode de réalisation de l'invention concerne un dispositif comprenant un circuit d'attaque de haut-parleur comprenant une membrane. Le dispositif comprend en outre un contrôleur configuré pour recevoir un signal source pour la reproduction par le biais du circuit d'attaque de haut-parleur, déterminer un déplacement estimé de la membrane résultant de la reproduction du signal source, et générer une tension de commande sur la base des informations de déplacement et de seuil estimées concernant un déplacement en toute sécurité de la membrane. Un déplacement réel de la membrane pendant la reproduction du signal source est commandé en se basant sur la tension de commande.
