Title (EN) HANDHELD DEVICE HAVING ULTRASONIC TRANSDUCER FOR AXIAL TRANSMISSION OF ACOUSTIC SIGNALS
(FR) DISPOSITIF PORTATIF A TRANSDUCTEUR ULTRASONORE POUR LA TRANSMISSION AXIALE DE SIGNAUX ACOUSTIQUES
Abstract: front page image
(EN)A handheld stylus (200) having an elongated housing (210), a writing and drawing implement (230) disposed within the housing and including a tip (242) extending through an opening at an end of the housing where ultrasonic waves radiate therefrom and are used for determining a position of the stylus; and at least one ultrasonic transducer (110) disposed within the housing. The transducer (110) may be a cylindrical piezoelectric transducer having a holder and a cylindrical piezoelectric film spanning between at least two spaced apart cylindrical surfaces of the holder, or a flat transducer having a diaphragm, and a piezoelectric material disposed on a surface of the diaphragm.
(FR)L'invention concerne un stylet portatif à enceinte allongée dans laquelle se trouve un stylet d'écriture et de dessin, avec extrémité s'étendant par une ouverture en bout d'enceinte, aux fins de rayonnement d'ondes ultrasonores en vue de la détermination de la position du stylet; et au moins un transducteur ultrasonore placé dans l'enceinte. Le transducteur peut être un transducteur piézo-électrique cylindrique à étui et film piézo-électrique cylindrique entre au moins deux surfaces cylindriques espacées de l'étui, ou un transducteur plat à diaphragme, et matériau piézo-électrique sur la surface du diaphragme.
