The invention relates to an electromagnetic converter for reproducing sound as well as to a method for assembling an electromagnetic converter. The converter comprises a so called inverted loudspeaker consisting of voice coil means (1), a magnetic circuit (5-6, 8-11) and a diaphragm (2) which are to be assembled in a basket (4). The magnetic circuit comprises a pre-magnetisable magnet (10). There can also be two pre-magnetisable magnet disks (5, 10) of opposite polarisation on either side of a magnet core in two parts (6, 11). In order to join the core parts (6, 11) with great precision, male and female guiding means (6:1, 11:1) are arranged on the core parts (6, 11). |
