Title (EN) METHOD AND APPARATUS FOR IN-ROOM LOW-FREQUENCY SOUND POWER OPTIMIZATION
(FR) PROCÉDÉ ET APPAREIL D'OPTIMISATION DE PUISSANCE SONORE BASSE FRÉQUENCE DANS UNE PIÈCE
Abstract:
(EN) One embodiment provides a device comprising a speaker driver, a microphone configured to obtain a measurement of a near-field sound pressure of the speaker driver, and a controller. The controller is configured to determine a velocity of a diaphragm of the speaker driver, and automatically calibrate sound power levels of audio reproduced by the speaker driver based on the velocity and the measurement of the near-field sound pressure to automatically adjust the sound power levels to an acoustic environment of the device.
(FR) Un mode de réalisation de l'invention concerne un dispositif comprenant un circuit d'attaque de haut-parleur, un microphone configuré pour obtenir une mesure d'une pression sonore en champ proche du circuit d'attaque de haut-parleur, et un contrôleur. Le contrôleur est configuré pour déterminer une vitesse d'un diaphragme du circuit d'attaque de haut-parleur, et étalonner automatiquement des niveaux de puissance sonore de l'audio reproduit par le circuit d'attaque de haut-parleur sur la base de la vitesse et de la mesure de la pression sonore en champ proche afin d'ajuster automatiquement les niveaux de puissance sonore à un environnement acoustique du dispositif.
