Title (EN) CALIBRATING A VIBRATIONAL OUTPUT DEVICE
(FR) ÉTALONNAGE D'UN DISPOSITIF DE SORTIE VIBRATOIRE
Abstract:
(EN) Examples are disclosed herein that relate to avoiding mechanical noise from operation of a vibrational output device. One example provides a computing device including a processor and a storage device storing instructions executable by the processor to vary a drive voltage applied to a vibrational output device, receive acoustic data, and from the acoustic data detect a noise signal from the vibrational output device as the drive voltage is varied. The instructions are further executable to, based upon the detected noise signal, select an operational drive voltage for the vibrational output device, and operate the vibrational output device using the operational drive voltage.
(FR) L'invention concerne des exemples pour éviter un bruit mécanique provenant du fonctionnement d'un dispositif de sortie vibratoire. Un exemple concerne un dispositif informatique comprenant un processeur et un dispositif de stockage stockant des instructions exécutables par le processeur afin de faire varier une tension de commande appliquée à un dispositif de sortie vibratoire, de recevoir des données acoustiques, et à partir des données acoustiques, de détecter un signal de bruit provenant du dispositif de sortie vibratoire lorsque la tension de commande varie. Les instructions sont en outre exécutables pour, sur la base du signal de bruit détecté, sélectionner une tension de commande de fonctionnement pour le dispositif de sortie vibratoire, et faire fonctionner le dispositif de sortie vibratoire à l'aide de la tension de commande de fonctionnement.
