Patent

CA 2512794

A number of ear-worn hearing system devices (30, 130, 230, 440, 540) are provided that each include a pair of electrodes (32, 132, 232, 432, 532) to transmit time varying electrical signals therebetween when coupled with skin of a user's body. The devices each include a housing (41a, 41b, 141), a sound sensor (45, 145), and processing circuitry (48, 148) included within the housing (41a, 41b, 141). The electrodes are coupled to the circuitry and are spaced apart from one another a distance sufficient to provide capacitance between the electrodes (32, 132, 232, 432, 532) below a desired threshold. The electrodes (32, 132, 232, 432, 532) are disposed along the housing for placement on locations of the user's body where coupling is not likely to be disrupted by nominal body movements.

L'invention concerne un certain nombre de dispositifs d'audition (30, 130, 230, 440, 540) portés dans l'oreille, qui comprennent chacun une paire d'électrodes (32, 132, 232, 432, 532) entre lesquelles sont transmis des signaux électriques variables dans le temps lorsque les électrodes sont en contact avec la peau du corps d'un utilisateur. Ces dispositifs comprennent chacun un logement (41a, 41b, 141), un capteur sonore (45, 145), et un ensemble de circuits de traitement (48, 148) montés au sein dudit logement (41a, 41b, 141). Les électrodes sont raccordées à l'ensemble de circuits et sont séparées l'une de l'autre par une distance suffisante pour qu'une capacitance soit fournie entre lesdites électrodes (32, 132, 232, 432, 532) en-dessous d'un seuil désiré. Ces électrodes (32, 132, 232, 432, 532) sont disposées le long dudit logement en vue d'un positionnement sur des emplacements du corps de l'utilisateur où le contact n'est pas susceptible d'être interrompu par des mouvements nominaux du corps.
