An acoustic transducer (10) includes a perforated member (12); a movable diaphragm (16) spaced from the perforated member (12); spring means (54, 56, 58, 60) interconnecting the diaphragm (16) and the perforated member (12) for movably supporting the diaphragm (16) relative to the perforated member (12); a pressure equalization slot (26) for controlling the flow of fluid through the diaphragm (16), the slot (26) equalizing the pressure on opposite sides of the diaphragm (16) for defining the low frequency response; and means (32) for applying an electric field across the perforated member (12) and the diaphragm (16) for producing an output signal representative of the variation of the space between the perforated member (12) and the diaphragm (16) in response to an incident acoustic signal.
Un transducteur acoustique (10) comprend un élément perforé (12); une membrane mobile (16) espacée de l'élément perforé (12); un dispositif à ressort (54, 56, 58, 60) interconnectant la membrane (16) et l'élément perforé (12), qui permet de supporter de manière amovible la membrane (16) par rapport à l'élément perforé (12); une fente d'égalisation de pression (26) régulant l'écoulement de fluide dans la membrane (16), la fente (26) égalisant la pression sur les côtés opposés de la membrane (16) pour définir la réponse basse fréquence; et un élément (32) servant à appliquer un champ électrique dans l'élément perforé (12) et la membrane (16) pour générer un signal de sortie représentatif de la variation de l'espace entre l'élément perforé (12) et la membrane (16) en réponse à un signal acoustique incident.
