Title (EN) MICROPHONE WITH AUTOMATIC BIAS CONTROL
(FR) MICROPHONE AVEC COMMANDE DE POLARISATION AUTOMATIQUE
Abstract: front page image
(EN)A microphone comprising an automatic bias control providing a better signal quality is proposed. The microphone comprises a bias control circuit that can provide two or more voltages to the microphone's capacitor. The bias control circuit increases the voltage if the collapse frequency is low and decreases the voltage if the collapse frequency is high.
(FR)L'invention concerne un microphone comprenant une commande de polarisation automatique offrant une meilleure qualité de signal. Le microphone comprend un circuit de commande de polarisation qui peut fournir deux ou plusieurs tensions au condensateur du microphone. Le circuit de commande de polarisation augmente la tension si l'affaissement de fréquence est faible et diminue la tension si l'affaissement de fréquence est élevé.
