Abstract

The invention relates to an electroacoustic transducer, the diaphragm of which is of the hemispherical cap type and which comprises an annular portion (4) resiliently supported at its external periphery and enclosed at the internal periphery (6) between two adjacent damping discs (7), coupled to an equalizing element (9), for example, through a pressure washer (14) and clamping device (12, 13). The diaphragm thus formed has its active or radiating part between the attachment of the external periphery to the supporting resilient structure (5) and the internal periphery (6) confined between the two damping discs (7).
