Patent

CA 2413410

In a transducer for emission and pick-up of mechanical vibrations, a center body (4) is suspended in a piezoelectric and elastic suspension structure (3) in a surrounding framework (2). The suspension structure (3) is sector divided, and has separate signal conductors for each respective sector (5), so that vibrations can be transmitted and received simultaneously with different sectors (5). Besides, the center body (4) may be equipped with piezo-elements of its own.

L'invention concerne un transducteur d'émission et de captage de vibrations mécaniques dans lequel un corps central (4) est suspendu dans une structure de suspension piézoélectrique et élastique (3) placée dans un cadre périphérique (2). La structure de suspension (3) est divisée en secteurs et présente des conducteurs du signal séparés pour chaque secteur respectif (5), de sorte que les vibrations puissent être transmises et reçues simultanément avec différents secteurs (5). De plus, le corps central (4) peut être équipé d'éléments piézoélectriques propres.
