Title
(EN) TRANSPARENT SOUND DEVICE
(FR) DISPOSITIF SONORE TRANSPARENT
Abstract
(EN)
An in-ear device includes a housing shaped to hold the in-ear device in an ear of a user, and an audio package, disposed in the housing, to emit augmented sound. A first set of one or more microphones is positioned to receive external sound, and a controller is coupled to the audio package and the first set of one or more microphones. The controller includes a low-latency audio processing path, digital control parameters, and logic that when executed by the controller causes the in-ear device to perform operations. The operations may include receiving the external sound with the first set of one or more microphones to generate a low-latency sound signal; augmenting the low-latency sound signal by passing the low-latency sound signal through the low-latency audio processing path to produce an augmented sound signal; and outputting, with the audio package, the augmented sound based on the augmented sound signal.

L'invention concerne un dispositif intra-auriculaire comprenant un boîtier formé de sorte à maintenir le dispositif intra-auriculaire dans une oreille d'un utilisateur, et un progiciel audio, placé dans le boîtier, pour émettre un son augmenté. Un premier ensemble d'un ou plusieurs microphones est placé de sorte à recevoir un son externe, et un contrôleur est couplé au progiciel audio et au premier ensemble d'un ou plusieurs microphones. Le contrôleur comprend un trajet de traitement audio à faible latence, des paramètres de commande numérique, et une logique qui, lorsqu'elle est exécutée par le contrôleur, amène le dispositif intra-auriculaire à effectuer des opérations. Les opérations peuvent comprendre la réception du son externe avec le premier ensemble d'un ou plusieurs microphones pour générer un signal sonore à faible latence ; l'augmentation du signal sonore à faible latence en faisant passer le signal sonore à faible latence par le trajet de traitement audio à faible latence pour produire un signal sonore augmenté ; et l'émission, avec le progiciel audio, du son augmenté sur la base du signal sonore augmenté.
