Patent

CA 2203583

A sound or ultrasound sensor is provided for transmitting and/or receiving sound or ultrasound, which is mechanically robust and chemically resistant and which has an adjustable emission characteristic, for example having a preferably small beam angle, having an emitting element (3) which has a flat front surface (34), and having a transducer element (1), the transducer element (1) causing the front surface (34) to oscillate on the basis of an excitation frequency, such that the entire front surface (34) carries out virtually in-phase deflections with virtually equal amplitude parallel to the normal to the front surface (34), and in which sensor concentric webs (32) are arranged on the front surface, there being a concentric gap (33) in each case between two adjacent webs (32), and a disk (5) sealing the sound or ultrasound sensor flush at the front, which disk is firmly connected to the webs (32) and has segments which are not connected to the webs (32) and are used as membranes (51).

L'invention est un capteur de sons ou d'ultrasons mécaniquement robuste et résistant aux substances chimiques qui est utilisé pour émettre et/ou recevoir des sons ou des ultrasons. Ce capteur a une caractéristique d'émission ajustable, par exemple une ouverture de faisceau étroite. Il comporte un élément émetteur (3) à surface avant plane (34) et un élément transducteur qui fait osciller cette face avant (34). Des tissus concentriques de capture (32) sont placés sur la face (34) avant avec un écart concentrique (33) entre chaque paire de tissus adjacents (32), ainsi qu'un disque (5) servant de joint d'étanchéité aux capteurs de sons ou d'ultrasons à l'avant, ce disque étant solidement fixé aux tissus (32) et comportant des segments non connectés à ces tissus (32) et utilisés comme membranes (51).
