Description

(54) ЭЛЕКТРОАКУСТИЧЕСКИЙ ПРЕОБРАЗОВАТЕЛЬ(54) ELECTROACOUSTIC CONVERTER

крывающего перфорационные отверсти  9 металлической диафрагмы 7.covering the perforations 9 metal diaphragm 7.

В предлагаемом электроакустическом преобразователе при по влении избыточного давлени  под защитной решеткой 2 эластична  мембрана 8 прижимаетс  к металлической диафрагме 7, котора  в свою очередь прижимаетс  к диску 5. В результате этого происходит герметизаци  той части кожуха 1, в которой укреплена головка 4 электроакустического преобразовател .In the proposed electroacoustic converter, when an overpressure occurs under the protective grid 2, the elastic membrane 8 is pressed against the metal diaphragm 7, which in turn is pressed against the disk 5. As a result, the part of the housing 1 is sealed in which the head 4 of the electroacoustic converter is fixed.

Использование изобретени  позвол ет обеспечить защиту электроакустического преобразовател  от избыточного давлени , кроме того , обеспечивает защиту электроакустического преобразовател  от попадани  влаги. Электроакустический преобразователь может найти применение дл  работы в услови х периодического воздействи  избыточного гидростатического или атмосферного давлени .The use of the invention permits protection of the electroacoustic converter against overpressure, furthermore, it provides protection of the electroacoustic converter against the ingress of moisture. The electroacoustic transducer can be used to operate under the conditions of periodic exposure to excessive hydrostatic or atmospheric pressure.
