Title (EN) IMPROVED SOUND PLAYBACK FROM A DEVICE WITH A VIBRATING MECHANICAL ACTUATOR
(FR) RESTITUTION SONORE PERFECTIONNÉE À PARTIR D'UN DISPOSITIF À ACTIONNEUR MÉCANIQUE VIBRANT
Abstract:
(EN) The invention concerns the playing back of a piece of multimedia sound content by means of the vibration of any radiating structure, produced by contact with a playback device (DIS) comprising: - a mechanical actuator (AC1, AC2) applying vibratory excitation to the structure, from a source signal, corresponding to a multimedia sound signal, - a sensor (C1) sensing a signal from the vibration of the radiating structure, in order to thus: supply the actuator with a source signal, of known frequency components, receive, from the sensor, a vibration signal from the radiating structure operated by the actuator, in order to obtain a frequency response from the radiating structure, correct the source signal supplied to the actuator, by applying a filter correcting the spectral response of the radiating structure such that this response, once corrected, has a flat spectral profile, with amplitude deviations at most of 5dB, and supply the actuator with the source signal corrected in this way.
(FR) L'invention concerne la restitution d'un contenu sonore multimédia par vibration d'une structure rayonnante quelconque, produite par contact avec un dispositif de restitution (DIS) comportant : - un actionneur mécanique (AC1, AC2) opérant une excitation vibratoire à la structure, à partir d'un signal source, correspondant à un signal sonore multimédia, - un capteur (C1) d'un signal issu de la vibration de la structure rayonnante, pour ainsi : alimenter l'actionneur avec un signal source, de composantes en fréquences connues, recevoir du capteur un signal de vibration de la structure rayonnante opérée par l'actionneur, pour obtenir une réponse en fréquences de la structure rayonnante, corriger le signal source alimentant l'actionneur, en appliquant un filtre correcteur de la réponse spectrale de la structure rayonnante pour que cette réponse, une fois corrigée, présente un profil spectral plat, avec des écarts d'amplitude au maximum de 5dB, et alimenter l'actionneur avec le signal source ainsi corrigé.
