Abstract

The body of the dynamic loudspeaker is fabricated in synthetic material and the front part of the surround (6) is injection- moulded integrally with the body (5). This body may be then screwed into the surround (7). The magnetic system of the loudspeaker consists of an annular permanent magnet (4) which has pole-pieces (1, 2 and 3), which are fixed to the body (5). There are annular rings on the body (10 and 11) which permit the attachment of the centering element (9) and the cone, (8) which is protected by a metal cover sheet (12).
