Title (EN) OSCILLATOR IN LIQUID
(FR) OSCILLATEUR IMMERGÉ DANS UN LIQUIDE
Abstract:
(EN) The invention relates to an oscillator in a liquid. The oscillator in the liquid includes an actuator element (1) oscillating in a reciprocating manner, and a sound-producing element (2) attached to the actuator element (1), whereby the actuator element (1) generates a motion in the sound-producing element (2) for producing a sound. The oscillator is made open, whereby the pressure of liquid acts both on a first surface (4) and on a second surface (5) of the wall of the sound-producing element while the sound source is in the liquid. The material and/or structure of the wall (3) of the sound-producing element is provided to be such that the distance between the first surface (4) and the second surface (5) of the wall varies as sound is produced.
(FR) L'invention concerne un oscillateur immergé dans un liquide. L'oscillateur immergé dans le liquide comprend un élément actionneur (1) effectuant un mouvement d'oscillation alternatif, et un élément générateur sonore (2) fixé à l'élément actionneur (1), l'élément actionneur (1) produisant un mouvement dans l'élément générateur sonore (2) pour produire un son. L'oscillateur est ouvert, de sorte que la pression de liquide s'exerce simultanément sur une première surface (4) et une seconde surface (5) de la paroi de l'élément générateur sonore lorsque la source sonore est immergée dans le liquide. Le matériau et/ou la structure de la paroi (3) de l'élément générateur sonore sont choisis de manière à ce que le son généré produise une variation de la distance entre la première surface (4) et la deuxième surface (5) de la paroi.
