<p>An electrodynamic transducer includes a magnet structure (14, 28, 30) having inner (31) and outer (14) poles defining between them an air gap (17), a diaphragm (12), and a voice coil (44). Openings (18) are provided in the outer pole (14), the openings (18) extending generally parallel with the air gap (17) and the direction of motion of the voice coil (44) in the air gap (17). The voice coil (44) is coupled to the diaphragm (12) by ribs (40) extending transversely across the air gap (17) and through the openings (18) for securing the voice coil (44) to the diaphragm (12).</p> |
