Изобретение относитс к области приборостроени , в частности к электроакустическим преобразовател м.The invention relates to the field of instrumentation, in particular to electroacoustic transducers.
Известны кансюли конденсаторных микрофонов , сигнал с которых снимаетс с помощью привинчиваемого в рабочей зоне мембраны токоотвода.Signs of condenser microphones are known, the signal from which is picked up with the help of a screw-down screw in the working area of the membrane.
Дл увеличени чувствительности и расширени динамического диапазона в предлагаемом устройстве токоотвод электрода номеш ,ен вне зоны рабочей площади мембраны в изол ционном крепежном кольце.To increase the sensitivity and expand the dynamic range in the proposed device, the electrode current lead is nomesh, outside the working area of the membrane in the insulating mounting ring.
На чертеже представлен описываемый капсюль конденсаторного микрофона.The drawing shows the described cap condenser microphone.
Мембрана, вынолненна из изол ционной пленки 1 с нанесенным на нее слоем металла 2, закреплена на неподвижном электроде 3 с помощью крепежного кольца 4 из изол ционного материала. Сквозь кольцо выведен контакт 5 дл сн ти сигнала с преобразовател . При этом слой металла нанесен в центральной рабочей зоне мембраны с небольшим отводом в нерабочую зону.The membrane, made of an insulating film 1 with a layer of metal 2 deposited on it, is fixed on the stationary electrode 3 by means of a fastening ring 4 made of an insulating material. Pin 5 is pulled out through the ring to remove the signal from the converter. In this case, the metal layer is deposited in the central working zone of the membrane with a small outlet to the non-operating zone.
Предмет изобретени Subject invention
Капсюль конденсаторного микрофона, состо щий из электрода, изол ционного крепежного кольца и мембраны, выполненной из изол ционной пленки с нанесенным на нее слоем металла, отличающийс тем, что, с цельюA condenser microphone cap consisting of an electrode, an insulating mounting ring and a membrane made of an insulating film coated with a metal layer, characterized in that, in order to
увеличени чувствительности и расширени динамического диапазона, токоотвод электрода номещен вне зоны рабочей площади мембраны в изол ционном крепежном кольце.increasing the sensitivity and widening of the dynamic range; the electrode lead current is located outside the working area of the membrane in the insulating mounting ring.
