CA 2684662

A sound transducer (1), comprising at least one acoustically neutral body (2) with which it is possible to associate two sound conveyance elements (9a, 9b) which are shaped approximately like a stylized funnel so as to each form an auricle (10a, 10b), which protrudes outside the acoustically neutral body (2) and is blended with a duct (19a, 19b) with which a three-pole microphone cartridge (25a, 25b) is associated, the cartridge being arranged so that its front end, adapted to acquire the sound, is proximate to the inlet of the duct. The two cold poles (29a, 29b) of the microphone cartridges are mutually inverted, so that the cold pole of one of the microphone cartridges and the hot pole (28a, 28b) and the ground (30a, 30b) of the other of the microphone cartridges are or can be connected to a same connector or socket (31a, 31b) which is or can be associated with a suitable amplifying and/or recording and/or processing device.

La présente invention concerne un transducteur sonore (1) qui comprend au moins un corps acoustique neutre (2) auquel il est possible d'associer deux éléments d'apport sonore (9a, 9b) qui sont approximativement de la forme d'un entonnoir stylisé afin que chacun forme une auricule (10a, 10b) qui sort du corps acoustiquement neutre (2) et qui est mélangé à un conduit (19a, 19b) avec lequel une cartouche de microphone tripolaire (25a, 25b) est associée, cette cartouche étant arrangée de manière à ce que sa partie avant, conçue pour acquérir le son, soit proche de l'entrée du conduit. Les deux pôles froids (29a, 29b) des cartouches du microphone sont mutuellement inverties de sorte que le pôle froid d'une des cartouches de microphone et que le pôle chaud (28a, 28b) et la mise à la terre (30a, 30b) de l'autre cartouche de microphone sont ou peuvent être connectées au même connecteur ou à la même prise (31a, 31b) qui est ou qui peut être associée à un dispositif d'amplification et/ou d'enregistrement et/ou de traitement adéquat.
