Sp\u00e9cifications techniques<\/h2>\n

Notre c\u0153ur de microphone \u00e0 conduction osseuse haute fid\u00e9lit\u00e9 9745 est dot\u00e9 d'un pompage d'impulsions pr\u00e9cis et de capteurs de micro-vibrations haute sensibilit\u00e9, garantissant une transmission pr\u00e9cise du signal et une r\u00e9sistance aux interf\u00e9rences, pour des performances audio sup\u00e9rieures.<\/p>\n

Circuit d'essai standard<\/h3>\n

\"Circuit<\/p>\n

Le circuit de test utilise une r\u00e9sistance de polarisation de 2,2k\u03a9, une tension d'alimentation continue de 4,5 V et un condensateur de couplage de sortie de 1\u03bcF, optimis\u00e9s pour l'acquisition de signaux de conduction osseuse.<\/p>\n

R\u00e9ponse en fr\u00e9quence typique<\/h3>\n

\"ECM-B9745AL70<\/p>\n

R\u00e9ponse en fr\u00e9quence : 100 Hz \u2013 20 kHz, effectivement 100 Hz \u2013 7 kHz, avec une r\u00e9ponse stable jusqu'\u00e0 3 kHz et un pic autour de 5 kHz pour une d\u00e9tection am\u00e9lior\u00e9e du signal.<\/p>\n
