Title (EN) SENSITIVITY ADAPTING TRANSDUCER
(FR) TRANSDUCTEUR À SENSIBILITÉ ADAPTATIVE
Abstract:
(EN) According to an embodiment, a sensor assembly (102) for converting ambient sound (104) into output signal (106) is adjusted in its sensitivity by a controller (128) which provides a sensitivity control signal (112), e.g. in the form of a variable bias voltage, to the sensor assembly (102) during operation of the sensor assembly (102). Hence, a bias voltage control may be used as sensitivity control for a microphone during operation. According to a further embodiment, the sensitivity control signal (112) to the sensor assembly (102) is varied so as to provide a dynamic range compression of the output signal (106) of the sensor assembly (102).
(FR) Selon un mode de réalisation, l'invention porte sur un ensemble capteur (102) destiné à convertir un son ambiant (104) en un signal de sortie (106) dont la sensibilité est ajustée par un organe de commande (128) qui fournit un signal de commande de sensibilité (112), par exemple sous la forme d'une tension de polarisation variable, à l'ensemble capteur (102) durant un fonctionnement de l'ensemble capteur (102). En conséquence, une commande de tension de polarisation peut être utilisée en tant que commande de sensibilité pour un microphone durant un fonctionnement. Selon un autre mode de réalisation, le signal de commande de sensibilité (112) appliqué à l'ensemble capteur (102) est fait varier de façon à produire une compression de gamme dynamique du signal de sortie (106) de l'ensemble capteur (102).
