Abstract
An electrodynamic acoustic transducer () is disclosed, which comprises a frame and/or a housing (), a membrane (), a magnet system () with a plurality of center magnets (′) having different magnetic orientations (M. . . M) and a coil arrangement () with a plurality of voice coils (), which are movably arranged relative to the magnet system () in an excursion direction (z). The ratio is below 1, wherein wdenotes the mean width of all airgaps (E) within the magnet system (), Adenotes the sum of all airgap areas within the magnet system (), hdenotes the mean height of the center magnets (′) and Adenotes the total area of the center magnets (′). Moreover, the invention relates to an electroacoustic system (), which comprises an electrodynamic acoustic transducer () of the above kind and a control circuit (CC) connected to the coil arrangement ().
