<p>An electrodynamic transducer (100) includes a magnet assembly (101) providing an air gap (118), a diaphragm (114) in the shape of a body at least partly defined by rotation of a segment of a two dimensional curve about an axis (126). The diaphragm (114) has a long edge (116), a short edge (128) and an apex, said short edge (128) and said apex lying in the air gap. A voice coil (120) is applied directly to a region of the diaphragm, which region lies in the air gap (118). A spider (124) positions the region of the diaphragm (114) to which the voice coil (120) is applied in the air gap (118). The spider (124) is coupled to the diaphragm (114) and the magnet structure (101). This electrodynamic transducer structure permits the implementation of designs which avoid the need for a voice coil form and eliminates excessive moving masses or excessive flexibilities.</p> |
