Description

В известных комбинированных микрофонах одностороннего приема, состо щих из приемника давлени  и приемника градиента давлени , согласование характеристик приемников, с целью получени  результирующей характеристики направленности, близкой к кардиоиде, существенно осложн етс  тем, что капсюли комбинированных конденсаторных микрофонов имеют единую сложную колебательную систему, в которой параметры и характеристики составл ющих приемников оказываютс  взаимосв занными .In the known unidirectional combination microphones consisting of a pressure receiver and a pressure gradient receiver, matching of receiver characteristics in order to obtain the resulting directional characteristic close to the cardioid is significantly complicated by the fact that the caps of the combined condenser microphones have a single complex oscillatory system the parameters and characteristics of the component receivers are interconnected.

Описываемый способ акустической коррекции результирующей характеристики направленности в одноэлементных микрофонах с одним подвижным электродом позвол ет обойти технологические трудности, св занные с получением у различных экземпл ров приемников характеристики направленности, близкой к кардиоиде, с достаточно резким минимумом приема под углом 180° к акустической оси. Сущность изобретени  заключаетс  в возможности независимого изменени  чувствительности приемника градиента давлени  посредством изменени  высоты узкой щели между тыльной стороной нерфорированного неподвижного электрода и дополнительным гладким диском.The described method of acoustic correction of the resulting directivity in single-element microphones with one movable electrode allows one to circumvent the technological difficulties associated with obtaining the characteristic of receivers of directional characteristics close to the cardioid with a rather sharp minimum of reception at an angle of 180 ° to the acoustic axis. The essence of the invention is the ability to independently change the sensitivity of the pressure gradient receiver by varying the height of the narrow gap between the back of the non-perforated fixed electrode and the additional smooth disk.

Конструктивна  схема, иллюстрирующа  применение описываемого способа акустической коррекции направленности, изображена на чертеже и состоит из мембраны /, прикрепленной через изолирующую прокладку 2 к неподвижному перфорированному электроду 3. Между электродом 3 и дополнительным диском 4, снабл енным выступающим щтифтом с резьбой, ввинчивающейс  в непОлТ,вижный электрод, имеетс  кольцеобразна  щель 5, высота которой регулируетс  вращением диска 4.A structural diagram illustrating the application of the described method of acoustic correction of the directivity is shown in the drawing and consists of a membrane / attached through an insulating gasket 2 to a fixed perforated electrode 3. Between the electrode 3 and the additional disk 4 provided with a protruding screw with a threaded screw screwed into the non-polarized The mobile electrode has an annular slot 5, the height of which is adjusted by rotating the disk 4.
