Sp\u00e9cifications techniques<\/h2>\n

L'ECM-B9750UL38-SD1033 est une capsule de microphone unidirectionnel haute performance con\u00e7ue pour la capture de sons directionnels pr\u00e9cis. Mesurant 9,7 \u00d7 5 mm, elle est dot\u00e9e de deux condensateurs et d'un c\u0153ur de micro RF cor\u00e9en, ce qui lui conf\u00e8re une forte r\u00e9sistance aux interf\u00e9rences RF et un fonctionnement stable.<\/p>\n

Avec une r\u00e9ponse en fr\u00e9quence de 50Hz~16KHz, cette capsule offre une reproduction audio claire et naturelle, ce qui la rend adapt\u00e9e aux microphones directionnels, aux syst\u00e8mes de conf\u00e9rence et aux appareils audio haute-fid\u00e9lit\u00e9. Sa conception compacte permet de l'int\u00e9grer facilement dans diverses applications.<\/p>\n

Pour les dispositifs n\u00e9cessitant des sondes pr\u00e9-attach\u00e9es, il convient de prendre en compte les \u00e9l\u00e9ments suivants Version avec plomb de 60 mm<\/a>.<\/p>\n

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

\"Circuit<\/p>\n

Conditions d'essai : R\u00e9sistance de charge (RL) = 680\u03a9, Tension d'alimentation (VS) = 1,5V, Condensateur de couplage (C) = 1\u03bcF.<\/p>\n

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

\"R\u00e9ponse<\/p>\n

La r\u00e9ponse en fr\u00e9quence s'\u00e9tend de 100 Hz \u00e0 16 kHz. La courbe augmente rapidement dans la plage des basses fr\u00e9quences, passe \u00e0 une mont\u00e9e plus graduelle autour de 2 kHz et commence \u00e0 s'att\u00e9nuer apr\u00e8s environ 12 kHz.<\/p>\n

\"Dimension<\/p>\n

Diam\u00e8tre : 9,7 mm ; hauteur : 5,0 mm. La face avant est recouverte d'un filet anti-poussi\u00e8re et la face arri\u00e8re comporte un orifice d'entr\u00e9e du son.<\/p>","protected":false},"excerpt":{"rendered":"
