发明名称 ELECTRICAL ACOUSTIC ASSEMBLY INCLUDING A DEVICE FOR THE RETENTION, ACOUSTIC SEALING AND VIBRATION ISOLATION OF AN ELECTROACOUSTIC CONVERTER
摘要 A device for the retention, acoustic sealing and vibration isolation of an electroacoustic converter (1) in an apparatus casing (8). The device includes an elastic, annular gasket (3), interiorly provided with a trough-like recess intended to close round a flange (2) on the converter, the outside of the gasket having a projecting shoulder face. The converter (1) with its gasket (3) is fitted into a collar (9) on the inside of the apparatus casing and is retained by a plurality of projections (10) on the inside of the collar, these pressing against said shoulder face and against the outside of the gasket, whereby there are also obtained acoustic sealing and vibration isolation.
