CA 2694286

The disclosed methods and devices incorporate a novel expandable bubble portion which provides superior fidelity to a listener while minimizing listener fatigue. The expandable bubble portion may be expanded through the transmission of low frequency audio signals or the pumping of a gas to the expandable bubble portion. In addition, embodiments of the acoustic device may be adapted to consistently and comfortably fit to any ear, providing for a variable, impedance matching acoustic seal to both the tympanic membrane and the audio transducer, respectively, while isolating the sound-vibration chamber within the driven bubble. This reduces the effect of gross audio transducer vibration excursions on the tympanic membrane and transmits the audio content in a manner which allows the ear to utilize its full inherent capabilities.

L'invention concerne des procédés et dispositifs incorporant une portion de bulle dilatable novatrice qui assure une fidélité supérieure à un auditeur tout en minimisant sa fatigue. La portion de bulle dilatable peut être dilatée par la transmission de signaux audio basse fréquence ou le pompage d'un gaz vers la portion de bulle dilatable. De plus, des modes de réalisation du dispositif acoustique peuvent être adaptés pour s'ajuster de manière cohérente et confortable sur une oreille quelconque, formant un joint acoustique variable à harmonie d'impédance à la fois pour la membrane du tympan et le transducteur audio, respectivement, tout en isolant la chambre de vibration sonore dans la bulle entraînée. Cela réduit l'effet d'excursions brutes de vibration du transducteur audio sur la membrane du tympan et transmet le contenu audio d'une manière permettant à l'oreille d'utiliser ses pleines capacités inhérentes.
